Description

Auxiliary device for transferring patients

Technical Field

The invention relates to the field of medical instruments, in particular to medical auxiliary equipment.

Background

Currently, patients often need to undergo examination, surgery or hospitalization during their medical procedures. In the above procedure, the patient needs an up-and-down examination apparatus (e.g., CT apparatus), or is transferred from a temporary bed to a fixed bed (e.g., from an emergency cart bed or an emergency room bed to an in-patient bed), or from a fixed bed to a temporary bed (e.g., from an in-patient bed to an operation bed). Therefore, if the patient is inconvenient to move during treatment, the patient needs to be carried by a companion (usually, 2 to 4 persons are needed).

Most examination departments are however equipped with only the medical staff responsible for operating the examination apparatus, without redundant auxiliary medical staff. If every patient needs to be carried by medical staff during examination, the workload of a hospital examination department is increased, and the examination efficiency is reduced. The cost of the hospital is increased by providing more auxiliary medical staff, and the manpower resource waste is caused. In view of the current manual conditions of hospitals, the following relatives are required to carry patients by themselves most of the time.

However, for some sudden accidents (such as traffic accidents), patients are usually sent to hospitals directly by emergency personnel, and no relatives can immediately arrive at the scene to assist medical personnel in carrying the patients (such as upper and lower examination equipment), and only the auxiliary medical personnel can be temporarily mobilized to assist in carrying. However, in these accidents, the patient is also severely damaged (such as viscera injury and rib fracture), secondary injury may be caused to the patient during the handling process, and the auxiliary medical staff is contraindicated for the factors that may take on medical responsibility, cause disputes between doctors and patients, etc., and is usually under great stress.

Moreover, with the increase in the pace of life and the increase in the aging of the population, the dominant labor in the home is always out. Therefore, when the old in the home needs hospitalization due to illness and accidental injury, the old is not accompanied with the doctor and careless, and is not helped to be carried (up and down inspection equipment or rotating bed), and the problem of daily cure is also raised.

In addition, the mode of relying on manual hand to carry realizes the transport, changes the bed, moves still mainly has following shortcoming:

1. In the aspect of coping with infectious diseases, the manual lifting and carrying can increase the infection risk of contact personnel.

2. The manual lifting and carrying can not achieve the balance of force and speed in the carrying process, and the pain of patients is easy to increase.

Based on this, it is an urgent problem to provide an auxiliary device for transferring patients.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings and specific embodiments. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present invention may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the invention to those skilled in the art.

Example 1

As shown in fig. 1, the auxiliary device for transferring patients provided in this embodiment mainly includes a sheet 1 for carrying patients, a support frame 2, a first support arm 3, a second support arm 4, and a tensioning arm 5.

Referring to fig. 2, the sheet 1 can be laid on a conventional examination apparatus carrying table, temporary bed or fixed bed for carrying a patient. In this embodiment, the sheet 1 has four hanging rings 11 symmetrically arranged, for example, the hanging rings 11 may be arranged adjacent to four corner top corners of the sheet 1. In this embodiment, in order to increase the load-bearing weight of the sheet 1, ribs are provided along the edges and the middle of the sheet 1. In general, the sheet 1 does not contain a metal substance so that it can be applied to an examination apparatus such as CT.

The support 2 can be directly fixed to the ground, or the support 2 can be movable, for example, rollers or pulleys may be provided at the bottom of the support 2.

Referring to fig. 3 and 4, the first support arm 3 has a first fixed arm 31 and a first moving arm 32, the first fixed arm 31 being fixedly provided vertically on the support frame 2, the first moving arm 32 being vertically movable along the first fixed arm 31 (in a vertical direction as shown in fig. 1 and 3).

The first support arm 3 in the present embodiment mainly includes a first fixed arm 31, a first moving arm 32, a first screw positioning bearing 33, a first ball screw 34, and a guide bearing 35. Specifically, the first fixing arm 31 is vertically provided on the support frame 2, and both end portions of the first fixing arm 31 are symmetrically provided with vertical grooves. The first moving arm 32 is disposed in the recess and is vertically movable along the first fixed arm 31. Taking the right groove as an example, the first ball screw 34 is vertically fixed on the first fixed arm 31 by a pair of first screw positioning bearings 33, and the first moving arm 32 is associated with the first ball screw 34 (for example, the first moving arm 32 itself has a threaded hole matching the first ball screw 34, or an additional fixed member having a threaded hole matching the first ball screw 34 is connected to the first moving arm 32), and the first moving arm 32 can vertically move along the first fixed arm 31 when the first ball screw 34 rotates. A guide bearing 35 for engaging the first stationary arm 31 may also be provided on the first movable arm 32, so that the guide bearing 35 is used to provide guidance and support for the vertical movement of the first movable arm 32.

Those skilled in the art will appreciate that stoppers 36 may be provided at both ends of the first ball screw 34 if necessary to limit the travel of the first moving arm 32.

Based on the above-described structure, it should also be understood by those skilled in the art that the grooves are not necessarily provided in a symmetrical fashion at both ends of the first fixing arm 31, and the grooves may have only one and be provided at the middle of the first fixing arm 31. Or the first fixing arm 31 may be cylindrical, and the grooves may be distributed along the circumference of the first fixing arm 31.

As shown in fig. 5, 6A and 6B, the second support arm 4 has a second fixed arm 41 and a second moving arm 42, the second fixed arm 41 being horizontally fixedly provided on the first moving arm 32, the second moving arm 42 being horizontally movable along the second fixed arm 41 (in the horizontal direction as shown in fig. 1). The second support arm 4 in the present embodiment mainly includes a second fixed arm 41, a second moving arm 42, a second screw positioning bearing 43, and a second ball screw 44. Specifically, the second fixed arm 41 disposed horizontally is fixedly connected to the first movable wall 32 (refer to fig. 3, that is, the second fixed arm 41 can vertically move under the driving of the first movable wall 32). The second ball screw 44 is provided inside the second fixed arm 41 through a pair of second screw positioning bearings 43. The second moving arm 42 is associated with a second ball screw 44 (e.g., the second moving arm 42 itself has a threaded bore that mates with the second ball screw 44, or an additional securing element is attached to the second moving arm 42 that has a threaded bore that mates with the second ball screw 44). When the second ball screw 44 rotates, the second moving arm 42 can move horizontally along the second fixed arm 41.

It should be noted that, as shown in the drawings, the second fixed arm 41 in this embodiment has an open inner space, and the second movable arm 42 is sleeved inside the second fixed arm 41, so as to enable the two to move horizontally (or be called as telescoping motion) with respect to each other. In order to ensure a smoother movement of the second moving arm 42, the inner side of the second fixed arm 41 and the outer side of the second moving arm 42 may be provided with guide bearings 45, respectively. It should be appreciated by those skilled in the art that the second fixing arm 41 is hollow in order to provide the second screw positioning bearing 43, the second ball screw 44, the guide bearing 45, etc. inside thereof, so as to prevent the potential safety hazard caused by the exposure. However, the second fixed arm 41 may be actually designed as a solid arm-like structure, the second ball screw 44 is provided on the outer surface of the second fixed arm 41 through a pair of second screw positioning bearings 43, and the second moving arm 42 is associated with the second ball screw 44. When the second ball screw 44 rotates, the second moving arm 42 can move horizontally along the second fixed arm 41 (i.e., the second fixed arm 41 and the second moving arm 42 are in a stacked up-down positional relationship).

Referring to fig. 7A and 7B, further, the second support arm 4 may further include a positioning plate 46, a rotation shaft 47, a suspension arm 48, and a suspension node 49. The positioning plate 46 is fixedly disposed at the end of the second moving arm 42, and the width of the positioning plate 46 is slightly greater than the width of the second moving arm 42. The rotation shaft 47 is symmetrically disposed at an end of the positioning plate 46 beyond the width of the second moving arm 42. The suspension arm 48 is fixedly provided on the rotation shaft 47 so that the suspension arm 48 can rotate relative to the second moving arm 42. The tensioning arms 5 are suspended by means of suspension nodes 49 provided on the suspension arms 48 (when two tensioning arms 5 are employed, as shown in fig. 1, they are actually in a state of overlapping one after the other).

Referring to fig. 8, the tensioning arm 5 in the present embodiment includes a hook 51, a vertical connecting rod 52, a first connecting member 53, a second connecting member 54, an elastic member 55, a main arm 56, and a sub arm 57. Specifically, the upper end of the vertical connecting rod 52 is used to connect with the second moving arm 42 (specifically, the suspension arm 48 on the second moving arm 42). The first connecting piece 53 is fixedly arranged at the lower end of the vertical connecting rod 52, and the second connecting piece 54 is slidably sleeved on the vertical connecting rod 52. The elastic member 55 is sleeved on the vertical connecting rod 52 and is located between the first connecting member 53 and the second connecting member 54. The two main arms 56 are symmetrically hinged to both ends of the second connecting member 54, and the hooks 51 are fixedly disposed at the ends of the two main arms 56. The secondary arms 57 have two, and both ends of each secondary arm 57 are hinged to the main arm 56 and the first link 53, respectively.

Therefore, in a general state, the second link 54 is held at a certain position on the vertical link 52 by the elastic force of the elastic member 55, and the two main arms 56 have an expansion angle directed obliquely downward. After the hook 51 is engaged with the hanging ring 11 on the bed sheet 1, the first moving arm 32 drives the vertical connecting rod 52 to lift upwards, and the second connecting piece 54 slides downwards to press the elastic piece 55 under the action of gravity of the patient. At this time, the unfolding angle of the two main arms 56 is increased until the maximum unfolding angle is reached, so that the sheet 1 is flattened to the maximum.

Based on the above structure, it should be understood by those skilled in the art that the greater the weight of the patient is during the uniform lifting of the first moving arm 32, the greater the compression of the elastic member 55 by the second connecting member 54, the greater the deployment angle of the two main arms 56, and the closer the hook 51 and the hanging ring 11 on the sheet 1 are engaged (similar to a locking structure).

When in use, the bed sheet 1 is laid on the prior examination equipment bearing table, temporary bed or fixed bed, and the patient lies on the bed sheet 1. The first movable arm 32 is vertically lowered, the horizontal position of the tensioning arm 5 arranged above the first movable arm is adjusted by the second movable arm 42, all the hooks 51 of the tensioning arm 5 hook all the hanging rings 11, and the bed sheet 1 is in the maximum flattening state under the tensioning force of the tensioning arm 5. Next, the operator vertically lifts the first moving arm 32 and adjusts the horizontal position of the tension arm 5 provided thereon with the second moving arm 42 so that the tension arm 5 is positioned above another examination apparatus carrying table, temporary bed or fixed bed to which the patient is to be transported. Subsequently, the operator lowers the first movable arm 32 again vertically, placing the sheet 1 together with the patient on another examination apparatus carrying table, temporary bed or stationary bed. Finally, all hooks 51 of the tensioning arm 5 are disengaged from all lifting eyes 11. The operator uses the auxiliary device to carry the patient.

It should be noted that one skilled in the art will appreciate that in some cases, the hanging ring 11 may have more hanging rings and may be symmetrically distributed along the edge of the sheet. The tensioning arm 5 may be provided only one and can be suspended directly from the second moving arm 42 without the aid of the suspension arm 48 and the suspension node 49 described above. At this time, the tensioning arm 5 has more hooks 51, main arms 56 and secondary arms 57 (as long as they are comparable to the number of lifting eyes 11), which can be designed to be distributed circumferentially along the vertical connecting rod 52.

Further, since the support frame 2 is designed to be movable, the present embodiment is provided with telescopic support legs 21 at the bottom of the support frame 2. The telescopic support leg 21 can enable a moving mechanism (such as a roller or a belt wheel) on the support frame 2 to be separated from the ground in the process of lifting a patient, so that the whole auxiliary equipment cannot move in the lifting process, and accidents are avoided.

Example 2

Referring to fig. 9 and 10, this embodiment is different from embodiment 1 in that the auxiliary device for transferring a patient further includes a third support arm 6, a bed fixing column 22, and a bed 7.

Specifically, the bed 7 is fixedly arranged on the support frame 2 through a bed fixing upright 22, and the bed 7 is used for laying the bed sheet 1. The third support arm 6 has a third fixed arm 61 and a third moving arm 62. The third fixing arm 61 is pivotally connected to the bed fixing column 22.

As shown in fig. 11, the third support arm 6 in the present embodiment includes a third fixed arm 61, a third moving arm 62, a slewing bearing 63, a third screw positioning bearing 64, and a third ball screw 65. The third fixing arm 61 is horizontally disposed on the bed fixing column 22 through a pivoting support 63, so that the third fixing arm 61 can horizontally rotate relative to the bed fixing column 22. The third ball screw 65 is provided inside the third fixed arm 61 through a pair of third screw positioning bearings 64. The third moving arm 62 is associated with a third ball screw 65 (e.g., the third moving arm 62 itself has a threaded bore that mates with the third ball screw 65, or an additional securing element is attached to the third moving arm 62 that has a threaded bore that mates with the third ball screw 65). When the third ball screw 65 rotates, the third moving arm 62 can horizontally move along the third fixed arm 61.

Similarly, as shown in the drawings, the third fixed arm 61 in this embodiment has an open inner space, and the third moving arm 62 is sleeved inside the third fixed arm 61, so as to enable the two to move horizontally (or be called as telescoping motion) with respect to each other. In order to ensure a smoother movement of the third moving arm 62, the inner side of the third fixed arm 61 and the outer side of the third moving arm 62 may be provided with guide bearings 66, respectively. It should be appreciated by those skilled in the art that the hollow design of the third fixing arm 61 is to provide the third screw positioning bearing 64, the third ball screw 65, the guide bearing 66, etc. inside thereof to prevent the potential safety hazard caused by the exposure. However, the third fixed arm 61 may be actually designed as a solid arm-like structure, the third ball screw 65 is provided on the outer surface of the third fixed arm 61 through a pair of third screw positioning bearings 64, and the third moving arm 62 is associated with the third ball screw 65. When the third ball screw 65 rotates, the third moving arm 62 can move horizontally along the third fixed arm 61 (i.e., the third fixed arm 61 and the third moving arm 62 are in a vertically stacked positional relationship).

Example 3

Referring to fig. 12 and 13, this embodiment is different from embodiment 2 in that the first fixed arm 31 is pivotally connected to the third movable arm 62, and the first movable arm 32 is pivotally connected to the second fixed arm 41, so that the first support arm 3, the second support arm 4, and the third support arm 6 can be in a horizontally stacked storage state by being mutually pivoted, and the height of the three horizontally stacked bed fixing posts 22 is less than or equal to the height of the bed fixing posts.

Further, referring to fig. 14, an end portion of the first moving arm 32 is bent to form a first bent end 321 (bent 45 degrees), and a disc-shaped (in this embodiment, a disc-shaped) first pivoting support lower link 322 is fixedly disposed on the first bent end 321. The first upper rotating support connecting piece 323 is buckled on the first lower rotating support connecting piece 322, and a first chamber 324 is formed between the first lower rotating support connecting piece 322 and the first upper rotating support connecting piece 323. The second fixing arm 41 is fixedly provided on the first slewing bearing upper link 323 (the second fixing arm 41 is kept in a horizontal state). The first driven gear 325 is fixedly disposed on the first slewing bearing upper link 323 and is located in the first chamber 324. The first motor 326 is fixedly disposed on the first bending end 321, and an output shaft of the first motor 326 passes through the first rotary support lower connecting member 322 and enters the first chamber 324. The first drive gear 327 is fixedly disposed on the output shaft of the first motor 326. A first conversion gear 328 is positioned within the first chamber 324 and engages the first driven gear 325 and the first drive gear 327, respectively, thereby transmitting power from the first drive gear 327 to the first driven gear 325.
