For example, the first equipment section 31, the second equipment section 32, the third equipment section 33, etc. are attached to any of the footboard 78B, the right first side rail 61, the left first side rail 61L, and the like. can be For example, a footboard 78B is provided with a holder 78Bh. A holder 61h is provided on the first side rail 61 on the right side. A holder 61Lh is provided on the left first side rail 61L. These holders include, for example, holes or recesses. For example, equipment parts are attached to these holders. The instrument part can be removed from the holder.

In the embodiment, the number of device units provided may be one, two, or three or more.

As shown in FIG. 1(a), a bed 70 is provided with a mattress 78M. A user of the bed 70 can lie on the mattress 78M. In the bed 70, a base frame 75B is provided, a bottom described later is provided thereon, and a mattress 78M is provided thereon.

An example of the bed 70 will be described below.
2(a) and 2(b) are schematic side views illustrating the bed apparatus according to the first embodiment. FIG.
As shown in FIG. 2(a), a back bottom 70a (back section), a knee bottom 70b (upper leg section), a leg bottom 70c (lower leg section), a height changing portion 70h, etc. are mounted on a base frame 75B. be provided. The back bottom 70a, the knee bottom 70b, the leg bottom 70c, and the height changing portion 70h are included in the movable portion 70M of the bed 70. As shown in FIG.

For example, the user's back angle can be changed by the movement of the back bottom 70a. The angle of the knee can be changed by the actions of the knee bottom 70b and the leg bottom 70c. These angles may be interlocked and changed.

As shown in FIG. 2B, the height changer 70h can change, for example, the distance H1 (height) between the floor surface and the bed surface. The height changer 70h may be able to change the height of the head side of the bed 70 and the height of the foot side of the bed 70 independently. Thereby, the inclination of the entire bed surface can be changed.

The angles of these bottoms may be changed by operating the buttons (the first operation receiving portion 30a, the second operation receiving portion 30b, etc.). The height of the bed 70 may be changed using the above buttons. For example, at least one of the first to third equipment units 31 to 33 can accept an operation to change the bottom angle and height of the bed 70 . Information about operations received by these equipment units may be supplied to the control unit 40 , and the angle and height of the bottom of the bed 70 may be changed by the control unit 40 .

The bottom and height changer 70h are operated by control of an actuator or the like, for example.

In one example, as shown in FIG. 2(a), a measuring device 20 (eg, load cell, etc.) is provided below the bottom. The user's weight exerts stress on the meter 20 . The measuring device 20 outputs, for example, a signal (for example, an electrical signal) according to body weight.

The control unit 40 is provided, for example, under the bottom. For example, a signal output from the measuring device 20 is supplied to the control section 40 .

FIG. 3 is a block diagram illustrating the bed apparatus according to the first embodiment;
As shown in FIG. 3, measuring device 20 is connected to control section 40 . A signal output from the measuring device 20 is supplied to the control section 40 .

As shown in FIG. 3, the control section 40 can be connected to, for example, the first to third equipment sections 31 to 33 . For example, the control unit 40 or the bed 70 is provided with first to third connectors 41 to 43 and the like. The first to third equipment units 31-33 can be connected to any one of the first to third connectors 41-43. Each of the first to third equipment sections 31 to 33 is connected to any one of these connectors. The control unit 40 controls the output (for example, display) of these equipment units.

On the other hand, the control section 40 controls the movable section 70M (for example, the back bottom 70a, the knee bottom 70b, the leg bottom 70c, the height changing section 70h, etc.).

For example, when weight is measured on the bed 70, the measurement is verified for the combination of the bed 70 and the equipment section. If this combination differs from the combination at the time of testing, the measured body weight will not be the value measured under the conditions tested.

In embodiments, the instrument portion is removable from the bed 70, as described above. For this reason, there is a possibility that the bed 70 is combined with equipment units that are not the specified combination. In this case, the measured result is not the desired result.

Identification information is given to clarify that it is a defined combination. For example, bed information that identifies the bed 70 is given to the bed 70 . First information identifying the first equipment section 31 is provided to the first equipment section 31 . Second information identifying the second instrument section 32 is provided to the second instrument section 32 . Third information that identifies the third equipment section 33 is provided to the third equipment section 33 . These pieces of information are unique numbers. These pieces of information may be settable (writable). For example, the first information may be configurable. These information may be overwritten. Examples of such identification information will be described later.

As shown in FIG. 3, for example, the control unit 40 (or bed 70) includes a bed storage unit 40M. The bed storage unit 40M stores bed information that identifies the bed 70 . For example, the bed storage unit 40M may be included in the measuring device 20. FIG.

For example, the first to third equipment units 31 to 33 respectively include first to third storage units 31M to 33M. The first storage section 31M stores first information for identifying the first equipment section 31 . The second storage section 32</b>M stores second information for identifying the second device section 32 . The third storage section 33M stores third information that identifies the third device section 33 .

For example, information about a prescribed combination (for example, a combination for testing) is stored in at least one of these storage units.

Based on these pieces of information, for example, it is determined whether or not there is a prescribed combination. The defined combination is, for example, the combination at the time of testing. This determination is made by the control unit 40, for example. The control section 40 controls the output of the equipment section based on this determination.

An example of the operation of the control unit 40 will be described below.

FIG. 4 is a flow chart diagram illustrating the operation of the bed apparatus according to the first embodiment.
The control unit 40 performs at least the following first operation. As shown in FIG. 4, the control unit 40 acquires bed information identifying the bed 70 and first information identifying the first device unit 31 (step S110). These pieces of information are acquired, for example, from the bed storage unit 40M and the first storage unit 31M.

The control unit 40 determines whether the bed information corresponds to the first information (step S120). For example, it is determined that "the bed information corresponds to the first information" when there is a predetermined combination.

In a first state where the bed information corresponds to the first information. The control unit 40 causes the first equipment unit 31 to output the measurement result (step S130).

In the second state in which the bed information does not correspond to the first information, the control section 40 does not cause the first device section 31 to output the measurement result (step S140).

By such an operation, for example, the measurement result (for example, the measured weight) is displayed on the display section 30d of the first device section 31 in the first state, which is the predetermined combination. On the other hand, in the second state, which is not the predetermined combination, the first device section 31 does not output (display) the measurement result.

This eliminates outputting an erroneous measurement result when the combinations are not determined. As a result, even if the equipment section can be removed from the bed 70, the measurement results can be output when the combination is determined, and the measurement results can be prevented from being output when the combination is incorrect.

In embodiments, the equipment section can be removed from the bed 70 for convenience. In such a case, a state (second state) that is not a defined combination may occur. At this time, in the embodiment, the output of the measurement result is controlled based on whether or not the combination is determined. According to the embodiment, it is possible to provide a bed apparatus that can conveniently output measurement results.

In the embodiment, the control unit 40 may cause the first equipment unit 31 to output information including that the bed information does not correspond to the first information in the second state (when not corresponding). Outputting information including that the bed information does not correspond to the first information may be included in the first action, for example. An example of output in such a case will be described later.

Such control in the first operation is effective when the device section (eg, the first device section 31 and the like) is removable from the bed 70 . For example, as previously described, bed 70 includes multiple holders. The plurality of holders includes, for example, holder 78Bh, holder 61h and holder 61Lh (see 1st (a)). These multiple holders can hold the first device section 31 . For example, the first device section 31 switches between a state of being held by one of the plurality of holders and a state of being held by another of the plurality of holders. It is convenient because it can be removed.

The control related to the first equipment section 31 as described above may be performed by the second equipment section 31 and/or the third equipment section 33 .

For example, the bed apparatus 110 further includes a second device section 31 capable of outputting the measurement result of the measuring device 20. FIG. Of the plurality of holders (holder 78Bh, holder 61h, holder 61Lh, etc.), holders that do not hold the first device section 31 can hold the second device section 32 . At this time, the control unit 40 can further perform the following second operation. In the second operation, the control unit 40 causes the second equipment unit 32 to output the measurement result in the third state in which the bed information identifying the bed 70 corresponds to the second information identifying the second equipment unit 32 . In the second operation, the control section 40 does not cause the second device section to output the measurement result in the fourth state in which the bed information does not correspond to the second information.

Similarly, the control unit 40 may be capable of further executing the following third operation. In the third operation, the control section 40 causes the third device section 33 to output the measurement result in the fifth state in which the bed information identifying the bed 70 corresponds to the third information identifying the third device section 33 . In the third operation, the control section 40 does not cause the third device section to output the measurement result in the sixth state in which the bed information does not correspond to the third information.

On the other hand, in the embodiment, the control section 40 or the bed 70 includes a plurality of connectors (eg, first to third connectors 41 to 43, etc.) to which the first equipment section 31 can be connected (see FIG. 3). The first device section 31 switches between a connected state in which it is held by one of the plurality of holders and a state in which it is connected to another of the plurality of holders.

Of the plurality of connectors (eg, first to third connectors 41 to 43 ), connectors that are not connected to the first equipment section 31 can be connected to the second equipment section 32 . At this time, the control unit 40 can further perform the second operation described above.

Of the plurality of connectors (eg, first to third connectors 41 to 43 ), connectors that are not connected to the first equipment section 31 can be connected to the third equipment section 33 . At this time, the control unit 40 can further perform the third operation described above.

As already explained, in one example, the control unit 40 includes a bed storage unit 40M that stores bed information that identifies the bed 70 . The first device section 31 includes a first storage section 31M that stores first information for identifying the first device section 31 . The control unit 40 reads out the bed information stored in the bed storage unit 40M and the first information stored in the first storage unit 31M, and performs the above first operation.

As already described, the second device section 32 may include a second storage section 32M that stores second information that identifies the second device section 32 . The control unit 40, for example, reads the bed information stored in the bed storage unit 40M and the second information stored in the second storage unit 32M, and performs the second operation.

As already explained, the third device section 33 may include a third storage section 33M storing third information for identifying the third device section 33 . The control unit 40, for example, reads the bed information stored in the bed storage unit 40M and the third storage information stored in the third storage unit 33M, and performs the third operation.

An example of assigning identification information will be described below.

In the embodiment, for example, the measuring device 20 (eg, load cell, etc.) provided on the bed 70 has a "serial number". If the bed 70 is provided with a plurality of load cells, for example, each of the plurality of load cells has a "serial number". The number of load cells provided on the bed 70 is four, for example. In one example, one “serial number” of a plurality of load cells is used as identification information (bed information) of the bed 70 . Multiple load cell "serial numbers" may be retrieved and associated with bed information.

For example, in initial setting of the first to third equipment units 31 to 33, information (first to third information) corresponding to bed information is given to the first to third equipment units 31 to 33. FIG. The given information (first to third information) is stored in the storage units (first to third storage units 31M to 33M) of the first to third device units 31 to 33, respectively.

The character string (or number) of the first to third information may be the same as the character string (or number) of the bed 70 identification information. For example, when the "serial number" of the measuring device 20 (for example, load cell) is "18507454", the bed information is "18507454". The first to third information of the first to third equipment units 31 to 33 are also set to "18507454". The first to third information may further include specific information regarding the first to third equipment units 31 to 33 in addition to the bed information "18507454". For example, the first information may be "1850745401".

The character string (or number) of the first to third information may be different from the character string (or number) of the bed information. In this case, the first to third information includes information relating to association between the first to third information and bed information.

In an embodiment, for example, the first information identifying the first equipment section 31 is written during testing so as to correspond to the identification information of the bed 70 with which the first equipment section 31 is combined. That is, the first information may be settable (writable or overwritable).

In this way, in the initial state, identification information (first to third information) of the first to third device units 31 to 33 may be determined in association with bed information. At least one of the identification information (first to third information) and the bed information regarding the equipment units may be displayed on the display units 30d of the first to third equipment units 31 to 33, respectively.

For example, in addition to body weight, tests may also be performed on various values measured by meter 20 (eg, body temperature, sound, etc.). In such a case, the measurement result can be output conveniently by performing the above operation.

(Second embodiment)
FIG. 5 is a block diagram illustrating the bed apparatus according to the second embodiment.

Bed 70 includes measuring device 20 . In this example, the bed 70 includes a movable portion 70M and a control circuit 40A that controls the movable portion 70M. In the bed apparatus 112, the control unit 40B is provided separately from the bed 70 and the first to third equipment units 31-33. In this example, a bed storage unit 40M that stores bed information for identifying the bed 70 is provided in the control circuit 40A or the control unit 40B.

In the bed apparatus 112, the control section 40B performs the operation (including determination) of the control section 40 described with regard to the first embodiment. Also in the third embodiment, it is possible to provide a bed apparatus that can conveniently output measurement results.

As described above, the bed apparatus according to the embodiment includes the bed 70 and the first equipment section 31 . Bed 70 includes measuring device 20 . Measuring device 20 measures the state of the user of bed 70 . The user's condition is, for example, the weight of the user. The first instrument section 31 is capable of outputting measurement results from the measuring device 20 . The first equipment section 31 can perform at least the first operation. In the first operation, the first device unit 31 outputs the measurement result in the first state in which the bed information identifying the bed 70 corresponds to the first information identifying the first device unit 31, and 31 does not output the measurement result in the second state where the bed information does not correspond to the first information.

Steps 110 to S140 illustrated in FIG. 4 may be performed, for example, in each of the first to third equipment units 31 to 33. FIG. For example, a controller may be provided for each of the first to third equipment units 31 to 33, and steps 110 to S140 may be performed by this controller.

FIGS. 7A and 7B are schematic diagrams illustrating the operation of the bed apparatus according to the embodiment.
FIG. 7(a) corresponds to the first state. In the first state, the bed information identifying the bed 70 corresponds to the first information identifying the first equipment section 31 . In such a first state, the display unit 30d displays "60.0 kg" as the measurement result MV. In this example, the measurement result MV is body weight. Thus, the measurement result MV is output in the first state. At this time, the previous measurement result MV2 may be displayed. In this example, "61.0 kg" is displayed as the previous measurement result MV2.

FIG. 7B corresponds to the second state. In the second state, the bed information identifying the bed 70 does not correspond to the first information identifying the first equipment section 31 . In this case, the measurement result MV is not displayed and an error message EM is displayed. In this example, the error message EM is a display of the contents of "the weight value cannot be displayed because the bed and the ID do not match". Thus, in the second state, the control unit 40 causes the first equipment unit 31 to output information (error message EM) including that the bed information does not correspond to the first information.

An example of the bed apparatus according to the embodiment will be described below.
FIG. 8 is a schematic perspective view illustrating the bed apparatus according to the embodiment;

Various switches and the like are also provided on these inner surfaces. The switches on the inside surface are designed, for example, to be conveniently operated by the user of bed 310B. Examples of these switches are described below.

Handrails 325g, 335g, 345g and 355g are provided on the upper portions of the right head siderail 320, the right foot siderail 330, the left head siderail 340 and the left foot siderail 350, respectively. The vertical width of these handrails is narrower on the inside than on the outside. This makes it easier for users to grasp these handrails, for example.

The upper surfaces of the handrails 335g and 355g of the right foot siderail 330 and the left foot siderail 350, respectively, are designed to be wide. The user can sit on these upper surfaces (edge sitting position). As a result, for example, when the user is sitting on the edge, the back of the thigh does not hurt.

The outer surface 320F of the right head side rail 320 and the outer surface 340F of the left head side rail 340 are provided with recesses. A bed handling device 380 can be attached to this recess. Further, a bed handling device 380 can be attached to the outer surface 370F of the footboard 370. As shown in FIG. Bed operating device 380 will be described later.

Examples of side rails are described below.

9(a) to 9(c) are schematic diagrams illustrating a part of the bed apparatus according to the embodiment.
As shown in FIG. 9A, the upper portion of the head right side rail 320 is provided with a through hole 325h. A handrail 325g is formed by the through hole 325h.

The upper portion of the head-right side rail 320 is further provided with a protrusion 325a, a recess 325b, a head-side protrusion 325c, and a head-side recess 325d. The protrusion 325a can be used, for example, as a support for supporting the user's body. When the head-right side rail 320 is raised (the back is raised), the concave portion 325b can be used, for example, as a support for supporting the user's body.

The user can easily grasp the head-side protrusion 325c. For example, when raising or lowering the back, the user's body is easily supported by the head-side protrusion 325c. A through hole is provided in the head-side protrusion 325c. Thereby, the head-side protrusion 325c can be used as a handrail.

Various medical lines can be inserted into the head-side concave portion 325d. Various lines are easy to stabilize. Medical lines include cables or tubes, such as, for example, ventilators and various ME equipment. By passing various lines through the head-side concave portion 325d, for example, it is possible to suppress entanglement of these lines.

The outer surface 320F of the head right side rail 320 is provided with a switch portion 323, a goniometer 324, a through hole 325e (eg hook portion) and a lower through hole 325f (eg Harunbag hook). A bed operating device 380 can be hung from the through hole 325e. A Harun bag can be hung from the lower through-hole 325f. A trash can or the like can be hung from the lower through hole 325f. For example, a hole 328h is provided below the through hole 325e. Cables of the bed handling device 380 can pass through the holes 328h. The cable is electrically connected to a connector provided on the bed apparatus 310 via the hole 328h. It is possible to suppress the cable from sticking to the floor. Cables can be shortened.

FIG. 9B exemplifies the switch section 323 .
The switch unit 323 is, for example, a membrane switch (for example, a membrane switch for medical personnel). The switch section 323 includes switches 323a to 323q.

When the switch 323a is pushed, "cardiac raising" is performed. When the switch 323b is pushed, "cardiac lowering" is performed. Bed 310B is brought to the cardiac position (see FIG. 16(b)) by "cardiac raising". "Cardiac Raise" The bed 310B moves toward the cardiac position while keeping the knee bottom 70b raised above the horizontal angle in a state where the angle between the back bottom 70a and the knee bottom 70b does not become extremely small. . As long as the angle between the back bottom 70a and the knee bottom 70b is not extremely small, the angle is less than 90 degrees. In a state in which the angle between the back bottom 70a and the knee bottom 70b is not extremely small, the user is prevented from being subjected to excessive abdominal pressure while maintaining a comfortable posture. For example, if the user tilts without raising the knees, the user may slip down. By raising the knee bottom 70b above the horizontal angle, the user is prevented from slipping down. By "cardiac lowering", the angle between the back bottom 70a and the knee bottom 70b does not become extremely small toward the state where the back angle is 0 degrees, the knee angle is 0 degrees, and the inclination angle is 0 degrees. In this state, the bed 310B operates while maintaining the state where the knee bottom 70b is raised above the horizontal angle.

When the switch 323c is pushed, "reverse extension" is performed. When the switch 323h is pushed, "stretching" is performed. In "stretching" the head is lowered. In "reverse extension," the foot is lowered.

When the switch 323d is pushed, "kind up" is performed. In "kind up", the angles of the back bottom 70a and the knee bottom 70b are interlocked and changed. When the switch 323i is pressed, "Kind Down" is performed. In "Kindokoro", the angles of these bottoms change in conjunction with each other. For example, when the angles of the back bottom 70a and the knee bottom 70b increase in conjunction with each other, the angle of the knee bottom 70b increases first, and then the angles of the other bottoms increase. This prevents the patient (user) from slipping. In "Kind Up", the state where the angle of the back bottom 70a is 70 degrees corresponds to the motion completion angle. The angle of the knee bottom 70b follows the angle of the back bottom 70a.

In "Kind Up", initially the back angle is 0 degrees and the knee angle is 0 degrees. Next, the back angle becomes 5 degrees and the knee angle becomes 0 degrees. Then the back angle becomes 15 degrees and the knee angle becomes 10 degrees. Furthermore, the back angle becomes 30 degrees, the knee angle becomes 25 degrees, the back angle becomes 50 degrees, and the knee angle becomes 25 degrees. After that, the back angle becomes 70 degrees and the knee angle becomes 0 degrees. In "kind up", the back angle and the knee angle increase in conjunction with each other until halfway. Above a certain back angle, the knee angle decreases toward 0 degrees.

In "Kind Down", initially the back angle is 70 degrees and the knee angle is 0 degrees. Next, the back angle becomes 50 degrees and the knee angle becomes 25 degrees. Further, the back angle becomes 30 degrees and the knee angle becomes 25 degrees. Further, the back angle becomes 15 degrees and the knee angle becomes 20 degrees. Further, the back angle becomes 0 degrees and the knee angle becomes 5 degrees. After that, the back angle becomes 0 degrees and the knee angle becomes 0 degrees.

When the switch 323e is pushed, "back raising" is performed. When the switch 323j is pushed, "back lowering" is performed.

When the switch 323f is pushed, "knee raising" is performed. When the switch 323k is pushed, "knee down" is performed.

When the switch 323g is pushed, "height raising" is performed. When the switch 323l is pushed, "height lowering" is performed. When the height of the bed 310B is raised in an inclined state, the height is raised while maintaining the inclination angle. The same applies to "down". Further, the bed 310B stops once when the maximum floor height is reached while remaining in the inclined state. When the height raising button (switch 323g) is pressed again after the bed 310B stops, priority is given to raising the height of the bed 310B, and the height is raised while setting the inclination angle to 0 degrees. The same applies to "down".

Switches 323c-323g for "up" are above switches 323h-323l for "down." For example, the user of bed 310B may touch the switch of switch section 323 unintentionally. At this time, the user of bed 310B is more likely to touch the upper portion than the lower portion. Since the switches 323c to 323g for "up" are on the upper side, even if the user accidentally touches the upper portion, the risk can be further reduced compared to the case of touching the switches 323h to 323l.

When the switch 323m is pushed, "CPR down" is performed. In "CPR down", the bed state is suitable for CPR (Cardio Pulmonary Resuscitation). In the "lower CPR" state, the knee bottom 70b and the leg bottom 70c become flat. In "lower CPR", the floor height of the bed 310B is lowered. In the tilted state, the tilt angle is also 0 degree. For example, the order of operations is as follows. The back angle is set to 0 degrees (while the back bottom 70a is being moved, the knee bottoms are also brought close to 0 degrees). Next, the tilt angle is set to 0 degrees. Then lower the height. Next, set the knee angle to 0 degrees. For example, the bed 310B may be at the lowest floor height. For example, in the bed 310B, a temporary stop position (temporary stop height) may be provided by the operation of "lowering the height". If the height is higher than this pause height in the state before "CPR down", "CPR down" brings the height of bed 310B to the pause height. At rest height, the distance from the floor to the bottom top surface is about 42 cm.

For example, in one example, a "hold" on switch 323m causes a "lower CPR". The “long press” time is, for example, two seconds or longer. In another example, a "double press" of switch 323m causes a "CPR down". When the switch 323m is "double-pressed", the time between "first-press" and "second-press" is within 5 seconds.

Actions other than CPR actions start when the button is pressed. Since the CPR operation is performed quickly in an emergency, the person operating the CPR operation button (switch 323m) may hesitate to press the CPR operation button. As described above, for example, the CPR operation is performed by "long-pressing" or "twice-pressing" the switch 323m. This allows the CPR operation to be performed without hesitation.

"CPR Down" is a power CPR operation. Alternatively, a manual CPR operation may be performed.

A switch 323n is a "nurse call". When the switch 323n is pushed, a nurse call is made. Information is communicated to the nurse call system.

When the switch 323o is pushed, the operation of a switch (described later) provided on the inner surface 320G of the head-right side rail 320 is put into a "prohibited state". When the switch 323p is pressed, all operations related to movement (actuator) of the bed 310B are "prohibited". In this case, "nurse call" and footlights, etc. are operational.

When the switch 323q is pressed, the footlight provided on the bed 310B or the like lights up.

In this example, the switch section 323 includes displays 323r-323t. A display 323r displays the remaining amount of the battery. The display 323s lights up (for example, orange) when the floor height is not the lowest. The display 323s is extinguished when the floor height is the lowest.

The display 323t displays an error. In normal operation, the display 323t disappears. At the time of "U system abnormality", the lighting for 1 second and the lighting for 1 second are repeated. At the time of "H system abnormality", 0.2 seconds on and 0.2 seconds off are repeated.

Operation by the switch portion 323 (eg, membrane switch for medical personnel) on the outer surface 320F has priority over operation by the later-described switch portion (eg, membrane switch for user) provided on the inner surface 320G. For example, if the outer and inner switches are pressed at the same time, neither will do anything. For example, when the back is raised on the outside and the knee-up button is pressed on the inside, the bed 310B stops. When both buttons are released and pressed again, the bed 310B operates.

FIG. 9(c) illustrates a goniometer 324 provided on the outer surface 320F of the head right side rail 320. FIG.
A recess is provided in the head right side rail 320 , and a goniometer 324 is formed by a sphere (for example, a metal ball) provided with the recess. When the back bottom is raised, the sphere rolls in the recess. The angle displayed on the display section 324a of the goniometer 324 changes according to the position of the sphere. A goniometer 324 provides an overview of the spine angle.

FIG. 17(b) illustrates a state in which the bed 310B is high. At this time, a caregiver or the like 399 can operate the bed operation device 380 while it is attached to the hook portion. The bed operation device 380 is attached to, for example, three hook portions. The three hook portions are the through-hole 325e of the head-right side rail 320, the through-hole 345e of the head-left side rail 340, and the through-hole 375e of the footboard 370.

Examples of electrical components in the bed apparatus 310 will be described below.

FIG. 18 is a schematic diagram illustrating the bed apparatus according to the embodiment;
As shown in FIG. 18, bed apparatus 310 is provided with control box 410 . In addition, various devices are provided in the bed device 310 . Various devices include junction box 420, membrane switch 430, footlight 440, side rail sensor 450 (SR sensor), caster lock sensor 455 (CL sensor), nurse call 457a, nurse call 457b, nurse call relay unit 458, scale It includes unit 460, load cell 465, actuator 470, battery 475, and the like. Some of the various devices may be omitted.

The control box 410 can be connected with various devices. Connections between control box 410 and various devices are made either directly or through junction box 420 . A control box 410 controls bed motion and various functions. Control box 410 serves as a master of serial communication in bed apparatus 310 .

The control box 410 is provided with a plug 410P (eg, 3-pin plug). Power is supplied to control box 410 from plug 410P. Power is supplied to various devices from the control box 410 .

Junction box 420 relays connections between control box 410 and various other devices.

Membrane switches 430 include healthcare worker membrane switches 430a and 430b. These membrane switches correspond to switch sections 323 and 343 . Membrane switches 430 include patient membrane switches 430c and 430d. These membrane switches correspond to switch sections 327 and 347 . The medical staff membrane switch 430a and the patient membrane switch 430c are connected to the junction box 420 via the relay unit 431a. The medical staff membrane switch 430b and the patient membrane switch 430d are connected to the junction box 420 via the relay unit 431b.

Medical staff membrane switches 430a and 430b are provided with bed operation buttons (switches). As already explained, the bed operation buttons include a cardiac operation button (e.g., interlocking operation button), an extension/reverse extension button, a kind motion operation button (e.g., another interlocking operation button), a CPR button, and a nurse call button. button, patient membrane switch inhibit button, and all switch inhibit button. The operations described with respect to the switch units 323 and 343 are performed by these bed operation buttons.

The patient membrane switches 430c and 430d are provided with bed operation buttons. As already explained, the bed operation buttons include the back bottom operation button, knee bottom operation button and nurse call button. Patient membrane switches 430c and 430d may include charging terminals and the like.

In the medical staff membrane switches 430a and 430b and the patient membrane switches 430c and 430d, the bed operation button is provided at an intermediate position in the vertical direction. If the bed operation button is at the bottom, it is difficult to operate. If the bed operation button is on the top, it may be operated by mistake. Since the bed operation button is located in the middle position in the vertical direction, the operation is facilitated and erroneous operation can be suppressed.

The footlight button corresponds to switches 323q and 343q. When the footlight button is pressed, the footlight 440 lights up. The footlight 440 illuminates the floor from the end of the bed 310B. For example, one leg lamp 440 is provided on each of the left and right sides of the bed 310B. The leg lamps 440 are provided, for example, at the left and right ends on the back side (lower side) of the waist bottom 70e. The leg lamps 440 may be provided in other parts such as the back bottom 70a, the knee bottom 70b, and the leg bottom 70c (see FIG. 16(b), etc.). For example, each time the footlight button (switches 323q and 343q) is pressed, the footlight 440 is repeatedly turned off, dimly lit, brightly lit, and extinguished. For example, the footlight 440 is turned on by a healthcare worker. For example, when the user frequently goes to the toilet, the medical staff turns on the footlight 440 before the user goes to bed. For example, when getting out of bed is detected, or when a nurse call occurs, the medical staff turns on the downlight 440 .

For example, when the user of the bed 310B leaves the bed at night to go to the bathroom or the like, the footlight 440 is turned on. At this time, the room is often dark. If the footlight 440 suddenly lights up brightly, it will be a nuisance to people sleeping nearby. By lighting dimly first, annoyance is suppressed.

A siderail sensor 450 detects whether each siderail is raised. Four siderail sensors 450 are provided. The four siderail sensors 450 include a right head siderail sensor, a left head siderail sensor, a right foot siderail sensor and a left foot siderail sensor. The detection result is displayed, for example, on the terminal of the nurse station. The detection result may be displayed on the bed operating device 380 . A warning sound may be generated based on the detection result. As the side rail sensor 450, for example, a magnetic sensor or an atmospheric pressure sensor is used. Other sensors may be used as the side rail sensor 450 .

The caster lock sensor 455 detects whether the casters 390C are locked. A magnetic sensor, for example, is used as the caster lock sensor 455 . For example, in caster 390C, a bar or the like is provided that interlocks with locking or unlocking of caster 390C. By detecting the state of the bar, the locked state of the casters 390C can be detected. The result of detection by the caster lock sensor 455 is displayed, for example, on the terminal of the nurse station. The detection result may be displayed on the bed operating device 380 . A warning sound may be generated based on the detection result of the caster lock sensor 455 .

Nurse call 457 a is connected to junction box 420 . Nurse call 457 b is connected to nurse call relay unit 458 . The nurse call relay unit 458 allows cooperation with nurse calls provided in hospitals and facilities (eg, nurse call 457b). Nurse calls 457a and 457b are domestic or foreign nurse calls. For example, the Nurse Call 457a is of foreign origin. For example, the Nurse Call 457b is made domestically.

Load cells 465 are provided at four corners of bed 310B. Four load cells 465 are used. The load cell 465 and scale unit 460 allow the weight of the user to be measured.

Actuators 470 include height change actuator 470a (“HLACT”), actuator 470b for knee bottom 70b (“knee ACT”), actuator 470c for back bottom 70a (“back ACT” with CPR), and Including height change actuator 470d (“HLACT”) and the like. Actuators 470a and 470d include load sensors.

In one example, actuator 470c for back bottom 70a includes a mechanical mechanism for manual lowering (hereinafter referred to as a manual CPR mechanism). The manual CPR mechanism allows the back bottom 70a to be manually lowered in an emergency. For example, a special lever or the like is provided, and by operating this lever, the back bottom 70a can be manually lowered to obtain a posture for CPR. For example, it is possible to manually offset the brake plate of the actuator 470c for the back bottom 70a. Thereby, the brake of the actuator 470c is released, and the back bottom 70a is lowered by its own weight.

Actuator 470 serves as a drive source for adjusting the movable portion included in bed 310B. The actuator 470 operates the movable part through a link mechanism or the like by the operation of the telescopic rod. A position sensor is provided for each of the actuators. Position information is read by the control box 410 . A load sensor of the actuator 470 may be used to determine movement (including, for example, leaving the bed) of the user (patient, etc.) on the bed 310B.

Battery 475 supplies power during a power outage or while bed 310B is being transported. Desired operation is obtained even in a situation where there is no power supply. A changeover switch for charging/not charging the battery 475 may be provided. Charging may be possible as long as power (AC power supply) is supplied to the bed 310B regardless of the state of the switch.

For example, when the bed apparatus 310 is powered by AC power, the control box 410 provides power to the battery 475, air mattress control unit 482 and USB charger 488 (see FIG. 18). Battery 475 provides power to control box 410, air mattress control unit 482 and USB charger 488 when power is not provided from the AC power source.

FIG. 23 is a schematic diagram illustrating a part of the bed apparatus according to the embodiment;
FIG. 23 illustrates back bottom 70a, knee bottom 70b, leg bottom 70c and waist bottom 70e. Each angle of the back bottom 70a, the knee bottom 70b, and the leg bottom 70c can be changed. Control is performed so that the angle between the bottoms does not fall below a predetermined value (eg, 90 degrees). For example, the angle between the line connecting the lower end of the back bottom 70a and the upper end of the knee bottom 70b (broken line in FIG. 23) and the back bottom 70a is controlled to be less than or equal to a predetermined value (eg, 90 degrees). be done. For example, the angle is reduced to a predetermined value or less by controlling (interlocking) the movement of any one of the plurality of bottoms.

The operating angle of the back bottom 70a is, for example, 0 to 70 degrees. The motion angle of the knee bottom 70b is 0 degrees or more and 25 degrees or less. The "height" operating range is, for example, 43 cm. The floor height may vary depending on the bed frame. Floor height ranges are, for example, 30 cm to 73 cm , 32.5 cm to 75.5 cm, or 35 cm to 78 cm.

The operating angle of the bottom tilt is -15 degrees to 15 degrees. For example, in order to avoid interference within the bed frame, the tilting operation is performed after adjusting the height to the height of "minimum floor height + 3 cm".

Cardiac position and movement to bottom flat involve lean movement. In these operations, an operation sequence is applied in consideration of the slippage of the user.

In the electric CPR operation, operations are performed in the following order. At that time, if simultaneous operations are possible, simultaneous operations may be performed. In the electric CPR operation, first, the stroke of the actuator 470c (“back ACT”) for the back bottom 70a is operated to the lower limit. The lower limit of actuator 470c is reached within 30 seconds after the button is pressed for power CPR operation. After that, a tilting operation is performed and the tilt angle becomes 0 degrees. After that, height adjustment is performed and the height becomes the minimum floor height. The minimum floor height is, for example, the "stop height". After that, the knee bottom 70b is moved to 0 degrees.

In the bed apparatus 310, by operating the bed operating device 380, button operations related to various operations can be put into an "operation prohibited" state.

24(a) and 24(b) are schematic diagrams illustrating part of the bed apparatus according to the embodiment.
These figures illustrate the display input section 380D of the bed operation device 380. FIG. 24A illustrates a case where the display input section 380D is the bed operation screen 381. FIG. FIG. 24B illustrates a case where the display input section 380D is the individual actuator operation prohibition screen 383 (bed setting screen).

As shown in FIG. 24(a), for example, buttons 382a to 382f are provided. These buttons are, for example, input receiving areas in a touch-type input device. Bed operation is performed by touching these buttons. Cardiac operation is performed by button 382a. A tilt operation is performed by the button 382b. A linked action (“Kind action”) is performed by the button 382c. Back movement (change of back angle) is performed by the button 382d. Knee motion (change of knee angle) is performed by the button 382e. Height operation (alteration of height) is performed by the button 382f. For example, to raise the back of bed 310B, pressing button 382d followed by raising button 380a moves bed 310B. The bed 310B moves while the lift button 380a is pressed. For example, when lowering the height of the bed, pressing the button 382f and then pressing the lowering button 380b lowers the height of the bed 310B while the lowering button 380b is being pressed.

As shown in FIG. 24(b), the display input unit 380D can shift to an actuator individual operation prohibition screen 383 (bed setting screen). By operating the display input area 383a, each of the back motion, knee motion, height motion, and tilt motion can be disabled individually. By operating the display input area 383b, all operations can be prohibited, or the operation prohibition can be released. By operating the display input area 383c, the operation of the hand switch 483 can be prohibited, or the operation prohibition can be canceled.

For example, when back movement is prohibited, cardiac movement, interlocking movement, and back movement are prohibited. For example, when knee motion is prohibited, cardiac motion, interlocking motion, and knee motion are prohibited. For example, when height motion is prohibited, cardiac motion, tilt motion, and height motion are prohibited. For example, when tilting motion is prohibited, cardiac motion and tilting motion are prohibited.

In one example, "lock all" is possible. In another example, actuators 470 (such as 470a-470d (see FIG. 18)) may be selectively (individually) "disabled." The release of the actuator 470 “operation prohibited” is released by the bed operating device 380 .

When the bed operating device 380 is removed from the bed 310B, or when the cable connecting the bed operating device 380 is broken, the selective “operation prohibition” of the actuator 470 cannot be released. At this time, the “operation prohibition” of the actuator 470 can be released by releasing the “all operation prohibition”.

Prohibition of operation of the actuator 470 and prohibition of operation of the hand switch 483 or "prohibition of all operations" are managed independently. For example, when the individual operation of the actuator 470 is prohibited, the individual operation of the actuator 470 remains prohibited even if "all operations are prohibited" and then "all operations are prohibited" is released.

When a disabled button is pressed, a buzzer sounds and the disabled LEDs of the membrane switch (eg, indications 323t and 343t, etc.) flash. If you don't hear the buzzer, you don't know if the button is prohibited or broken. A buzzer sounds to indicate that the button is prohibited.

When the prohibited button of the hand switch 483 is pressed, the hand switch 483 sounds. For example, the junction box 420 sounds when a prohibited button in the membrane switch is pressed.

By operating the medical staff membrane switch or bed operating device 380, the patient membrane switch and hand switch 483 can be disabled. Prohibition of operation can be canceled if the medical staff membrane switch or the bed operation device 380 is connected.

All operations can be prohibited by operating the medical staff membrane switch or the bed operating device 380 ("all operations prohibited"). This operation prohibition can be canceled if either the membrane switch for medical staff or the bed navigation system is connected.

For example, when the bed operating device 380 is not connected to the bed 310B, or when there is a partial failure (communication failure), the "prohibition of all operations" is cancelled. In this case, for example, the hand switch 483 can be operated. The hand switch 483 may be removed when the user does not operate it. When a disabled button is pressed, a buzzer sounds and the disabled LED on the membrane switch flashes.

When the "all operations are prohibited" button is pressed while the hand switch 483 is in the operation prohibited state, the "all operations are prohibited" state. After that, when "all operation prohibition" is pressed, the operation prohibition of the hand switch 483 and all operation prohibition are released. CPR operation is performed even when "all operations are prohibited". CPR is performed in any of the cases of "operation prohibited", "hand switch operation prohibited", and "all operations prohibited".

For example, when the hand switch 483 is neither operation prohibited nor “all operation prohibited” in the “current setting”, when the operation prohibit button of the hand switch 483 is pressed, the hand switch 483 becomes operation prohibited and “ All operations” is not prohibited (released state).

For example, when the hand switch 483 is neither operation prohibited nor all operation prohibited in the 'current setting', pressing the button for 'all operation prohibited' disables the hand switch 483 and all operations.

For example, if the operation prohibition button of the hand switch 483 is pressed when the operation prohibition button of the hand switch 483 is pressed in the "current setting", the hand switch 483 is not operated (cancel). state), and "all operations" are not prohibited (released state).

For example, in the "current setting", if the hand switch 483 is prohibited from operation and not "all operation prohibited", pressing the "all operation prohibited" button disables the hand switch 483 and all operations.

For example, when the hand switch 483 is prohibited from being operated and all operations are prohibited in the "current settings", pressing the operation prohibiting button of the hand switch 483 disables the hand switch 483 and all operations. .

For example, when the hand switch 483 is prohibited from being operated and is set to be "all operation prohibited" in the "current settings", when the "all operation prohibited" button is pressed, the operation of the hand switch 483 is no longer prohibited (released). state), and all operations are no longer prohibited (released state).

The operation speed can be changed by operating the display input area 383d illustrated in FIG. 24(b). For example, the speed of various operations can be changed in multiple steps (eg, two steps, etc.).

A history of various operations of the bed apparatus 310 may be stored. For example, the history is saved in a memory such as control box 410 . A memory in which the history is saved may be provided in the junction box 420, the hand switch 483, or the like. A memory in which the history is stored may be provided in the bed operating device 380 . Information about history is not reset by power on/off. The history information includes, for example, the operation history of the control box 410, the operation history of the actuator 470, the operation history of the hand switch 483, the operation content history, the failure history, and the bed leaving history.
