Generally speaking, the ergonomic functional bed for the old and the weak comprises a bed body, a remote communication alarm system, a matrix type gas compression propulsion system, a bed board turning mechanism, a leg bending mechanism and the like. The details of the structure and operation of the various parts will be further described with reference to the accompanying drawings.
The bed body of the ergonomic functional bed for the old and the weak comprises an upper bed plate, a lower bed plate, a bed head backup plate, a bed tail backup plate, a left side plate, a right side plate, a head lifting mechanism, a foot lifting mechanism and the like. The upper bed board is composed of four turnover side turning boards along the length direction, and the side turning boards are connected by hinges. The lower bed plate is internally provided with a curved leg rod. The bottom layer of the whole bed board is a supporting structure formed by an iron frame and an iron plate, a wood board is laid on the supporting structure, an elastic insulating material is used for laying on the wood board, and the bed surface is formed by covering flax materials. The air bag inflation subsystem is positioned above the wood board, in the elastic insulating material and below the flax bed surface. The side wall of the air bag is wrapped with green environment-friendly fiber materials which do not irritate human bodies, and the top of the air bag is wrapped with flax materials. The air bag is in a semi-inflated state at ordinary times, so that the whole bed surface is horizontal, and the bedridden people can not feel sunken. The pressure sensors are distributed below the bed surface, elastic insulating materials are distributed around the pressure sensors, the inflation control circuit has the functions of short-circuit protection and electric leakage protection, and the damage of the components due to overheating and electric leakage to the bedridden person is avoided.
FIG. 1 is a side view of the overall structure of the bed. The upper bed plate 4, the thigh bed plate 10 and the shank bed plate 12 can be turned upwards, and the shank bed plate is always parallel to the horizontal plane, so that the bedridden can have a rest on the legs conveniently, and the comfort is enhanced. The bed board is internally provided with an air bag 13 which has the functions of side turning and massage.
Fig. 2 is a schematic diagram of a driving and transmission part for realizing the turning-up of the upper bed plate 4, the thigh bed plate 10 and the shank bed plate 12, which is controlled by a motor through an electromagnetic clutch, and the clutch of the electromagnetic clutch can be controlled according to requirements so as to select the turning-up of the upper body or the turning-up of the legs or the linkage of the upper body and the lower body. The drive shafts 40 and 41 are connected to the motor shaft by a gear mechanism.
The matrix type gas compression propulsion system is composed of a pressure sensing subsystem and an air bag inflation subsystem. The pressure sensing subsystem is used for sensing the pressure distribution of the human body and indirectly measuring the relative position of the human body. The air bag inflating subsystem mainly comprises a plurality of small air bags, is controlled by a program and is inflated by an air compressor according to rules to achieve the effects of turning over and massaging the human body.
Fig. 3 is a bed board structure diagram provided with a matrix type gas compression propulsion system, and comprises an air bag 13, pressure sensors 121 and a bed board, wherein the pressure sensors are regularly distributed between the bed board and the air bag in a matrix manner, so that the human body prone position can be identified, a detection signal is returned, and the air bag is inflated as required.
FIG. 4 is a schematic view of an airbag inflation subsystem. The air bag inflation subsystem further comprises an air conveying pipe and an air electromagnetic valve, and the chip controls the electromagnetic valve to selectively inflate the air bag. Fig. 5 is a schematic diagram of turning over of the inflated airbag. The pressure sensor can return signals according to the position of the human body, and can inflate according to the current posture of the human body to help the human body to turn over.
In the ergonomic functional bed for the old and the weak, the air bags are inflated regularly and selectively, so that the effect of massaging the human body can be achieved. The pressure sensor can sense the position of a human body relative to the bed, can carry out inflation pressurization on the human body or a certain part of the human body, and achieves technical effects of lifting legs, massaging the back and the like.
The bed board turning mechanism comprises a turning mechanism and a lifting mechanism, wherein the turning mechanism is used for turning the human body on one side, and the lifting mechanism is used for enabling the human body to sit up and bend legs. The turning-over mechanism and the rising and lying mechanism both comprise a driving part and a transmission part, wherein the driving part comprises a motor and a corresponding worm gear mechanism, and the transmission part is connected with a relevant bed plate in the bed body for enabling a human body to act. The following description will be made separately.
Fig. 6 is a schematic diagram of the transmission part of the four side-turning plates with reference numbers 5, 6, 7 and 8 for realizing the side turning of the human body, which is suitable for the situation that the human body is in the middle position. The plates 7, 8 are identical to the drive parts under the plates 5, 6 and can only be turned inside the bed. Take one side as an example. An electromagnetic lock and a limit switch are arranged below each bed board, when the bed board is completely put down, the limit switch is touched, the electromagnetic lock is closed, and the bed board is fixed. When the body is turned over, the electromagnetic locks 65, 66 are closed and the transmission part is driven.
Fig. 7 is a schematic view of the transmission part when the side turning plate 8 turns over. The side turning plate 8 is the same as the transmission part of the side turning plate 5 and can only turn towards the inner side of the bed. When the human body is in the peripheral position, the transmission part is driven. When the electromagnetic lock 65 and the electromagnetic lock 66 are driven, the electromagnetic lock 76 is closed, and the transmission part is driven to realize the rollover. The electromagnetic locks 65, 66 are switched to open and close with the electromagnetic lock 76 to effect that either one of the transmission parts is driven.
Fig. 8 is a schematic view of the driving parts corresponding to the four side flaps 5, 6, 7, 8. 79, 80, 81 and 82 are worm and gear mechanisms, and each worm and gear mechanism outputs power to a transmission part connected with the four side turning plates through a transmission shaft, an electromagnetic clutch and a screw and nut mechanism so as to realize the turning of the four side turning plates (the worm and gear, the transmission shaft connected with the worm and gear, the electromagnetic clutch and the screw and nut mechanism are collectively called a worm and gear system). Taking the flipping of the side flippers 7, 8 in fig. 6 and the flipping of the side flipper 8 in fig. 7 as an example, the lever 69 in fig. 6 and the lever 77 in fig. 7 are driven by a worm gear system 82 and a worm gear system 81 in fig. 8, respectively. For example, the electromagnetic locks 65, 66 in fig. 6 are closed, the electromagnetic lock 76 in fig. 7 is opened, the electromagnetic clutch 90 in fig. 8 is engaged, the electromagnetic clutch to which the worm gears 79, 80, 81 are connected is opened, the lever 69 is pushed when the motor is started, and the side flaps 7, 8 are flipped (see fig. 6). Similarly, the electromagnetic locks 65, 66 in fig. 6 are opened, the electromagnetic lock 76 in fig. 7 is closed, the electromagnetic clutch 84 in fig. 8 is engaged, the electromagnetic clutch to which the worm gears 79, 80, 82 are connected is opened, the lever 77 is pushed by the motor being activated, and the side flap 8 is flipped (see fig. 7). Similarly, the worm and gear system 79, 80 can realize the turning of the side turning plates 5, 6, and will not be described herein.
It is well known that maintaining a bed-ridden position for an extended period of time increases the risk of bedsores developing in the body. At present, most nursing beds have a side turning function, but the bed plates are simply turned, if the lying posture of a human body is irregular, namely the human body lies along the diagonal line of the bed, the turning of the bed plates is simply turned, the turning cannot be realized, or danger is generated in the turning process. In the ergonomic functional bed for the old and the weak, not only the bed board is turned, but also the air bag is used for bumping during turning, so that the body movement during irregular bed lying of the human body is realized, and diseases such as bedsore and the like caused by the unchanged posture of the body lying in bed for a long time are effectively avoided.
According to the principle of human engineering, when a human body lies flat, the weight distribution of all parts of the body is that the hip is 40%, the back is 15%, the head is 10%, the feet are 10% and the waist is 25%, the current position of the human body on the bed can be sensed through a pressure sensor on the surface of the mattress, and therefore calculation can be carried out according to an algorithm in a chip, and whether a bed board is turned over or not and which bed board is turned over can be determined. When the pressure sensors distributed in the matrix calculate that the position of the human body is approximately in the middle of the bed plate, the left or right bed plate can be turned over towards the middle, and the turning angle is adjustable between 0 and 80 degrees; when the pressure sensor calculates that the prone position of the human body is irregular, the human body cannot be turned over in a mode of turning over the bed plate, the lying position of the human body can be detected according to the pressure sensor, when the human body is turned over to one side, the air bag on the other side is inflated, when the air bag is fully inflated, the human body is inclined, and the inclination angle is adjustable from 0 degree to 45 degrees.
In addition, when a human body turns over, the arm is easy to press down, the Chinese patent with the patent number ZL 01125633.8 is to pull the arm by a rope to avoid pressing down, but if the hemiplegic bedridden person or the bedridden person with weak hands is pulled by the rope for a long time, the hemiplegic bedridden person or the bedridden person with weak hands are easy to cause trauma or dislocation, and have potential danger; and the other technical proposal does not consider the situation that the turnover arm is pressed. The inventor considers that: the reason that the arms are pressed when the patient turns over is that the arms are close to the body when the patient lies on the back, and the patient does not move away when the patient turns over. Thus, with the pressure sensor provided on the bed, the position of the arm relative to the torso can be detected. Before turning over, the air bag between the arm and the trunk is fully inflated to force the arm and the trunk to leave a certain distance, and the air bag between the arm and the trunk is deflated along with the turning over plate on the other side or the inflation of the air bag, so that the arm is not pressed when the turning over is carried out.
The leg bending mechanism is composed of a leg bending rod and a corresponding drive transmission part. The mechanism is responsible for lifting the legs and toppling towards one side when a person lying in bed turns over so that the legs and the upper body form a certain angle and the comfort and the stability of lying on one side are improved. The leg-bending rod 11, see fig. 3, is located between the thigh bed plate 10 and the shank bed plate 12, is wrapped by leather, and is in a position horizontal to the entire bed surface when not in motion, i.e., the home position.
Fig. 9 is a schematic view of the driving and transmission part of the leg-bending lever 11. The whole mechanism is controlled by two motors for transmission, the motors are respectively connected with a screw nut system, and the push rod 103 and the rod 112 can slide upwards in the same horizontal rotating shaft by virtue of screw nut transmission boosting, so that the crank leg rod 11 is pushed to move upwards. The ends of the rod 103 and the rod 112 are connected with a sliding block and an electromagnetic lock, can slide in the inner slide way of the leg bending rod according to requirements, and can be locked with the leg bending rod 11 at any time. The sequence of motion of the leg-bending rod is shown in fig. 10 to 12.
After the human body turns over, the legs need to be bent so as to enable the human body to lie stably, and the posture of the legs after the human body turns over is not considered in most of the prior art. According to the principle of human engineering, when a person turns over, the person needs to find a fulcrum at the leg or the foot, and then the person turns over. By utilizing the principle, in the ergonomic functional bed for the old and the weak, the leg bending rod in the lower bed plate plays the role of turning over and bending legs, can realize the bending and lifting of the legs and the left and right falling with the feet as fulcrums, so that the legs keep a certain angle when turning over on one side and can stably lie on one side; the mechanism may also assist in performing flexion and extension exercises of the leg.
When the legs are bent, the mechanism moves upwards to prop against the lower sides of the knees to lift the two legs, the leg bending rod inclines leftwards or rightwards along with a control signal for turning over the legs leftwards or rightwards, and the legs fall leftwards or rightwards along with the cross rod by taking feet as fulcrums. When the mechanism is straightened, the cross rod of the mechanism is lifted to be horizontal and is equal to the height of the front part of the leg, the leg is lifted, the mechanism moves towards the bed plate to be completely returned, and the leg is put down conveniently.
In order to keep people stable after turning over and enhance the comfort, the legs need to be bent and turned over while turning over, and a certain angle is formed between the legs and the upper body, so as to achieve the purpose of stability and comfort. The leg-bending rods act on the lower side of the knees (see fig. 13), and the leg-bending action is performed in coordination with the turning-over action at the same time.
In fig. 10, the motor is operated to push the feed screw and nut mechanism, the nut moves towards the opposite side, and the leg bending rod is jacked up (the dotted line is the original position of the leg bending rod and is kept horizontal with the bed plate). At this time, the thigh and the calf are bent up, and the foot is supported on the bed, see the leg state side view of fig. 13.
In fig. 11, the electromagnetic lock in the slider mechanism 118 is locked, the nut on the lead screw moves from the dotted line to the solid line in the arrow direction, the slider mechanism 119 slides in the arrow direction, the rod 11 inclines to one side, and the leg is pushed by the rod 11 with the foot as the fulcrum and tilts to the same side along the same direction. In fig. 12, after the leg is tipped, the lever 11 is returned to the home position and the leg is placed in the bed with the leg bent.
When changing from lying on one's side to lying on the back, it is necessary to restore the legs from a bent state to an extended state, i.e. "straight legs". The leg-straightening action is completed by using the gravity of the leg part and taking the foot part and the hip part as fulcrums, and the leg-straightening action and the falling of the side turning plate of the upper body are coordinated and carried out simultaneously. The leg straightening action specifically comprises the following steps: the operation of fig. 10 is repeated, the lever 11 is lifted up horizontally, and the legs are raised up by the lever 11 with the feet and hips as fulcrums, and the state of fig. 13 is restored. Then, the rod 11 is horizontally lowered to the horizontal position with the bed board, and the thighs and the calves fall to the straight leg position along with the rod 11 by gravity, and the supine operation is completed.
