TECHNICAL FIELD

[0001] The utility model belongs to the technical field of medical devices, and particularly relates to a patient transfer device. BACKGROUND

[0002] Most patients who are inconvenient to move or lose the ability to move independently need to be transferred to other departments for examination. Usually, multiple medical staff need to cooperate to lift the patient and transfer him to a transfer bed or an examination table. However, such a transfer process is inconvenient and difficult to operate, and the patient may be injured again due to a slip. SUMMARY

[0003] In view of the technical problems of the prior art, such as inconvenient transfer operation, great difficulty, and possible secondary injury due to a slip, the utility model provides a patient transfer device.

[0004] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme:

[0005] A patient transfer device comprises two support assemblies arranged symmetrically and spaced apart and connected by a telescopic rod, a cloth body located between the two support assemblies and detachably connected to the corresponding support assembly at both ends and capable of being folded, and a controller arranged in one of the support assemblies. Each support assembly comprises two support frames arranged at intervals, two drive mechanisms corresponding to the support frames and electrically connected to the controller, two support plates connected to the drive mechanisms, and a horizontal telescopic structure connected between the two support plates. The drive mechanism can drive the support plate to reciprocate along the height direction of the support frame. The support plate and the horizontal telescopic structure are each provided with a plurality of connecting pieces that can be detachably connected to the cloth body. The horizontal telescopic structure is used to adjust the distance between the two support frames.

[0006] Further, the horizontal telescopic structure comprises a first frame arranged on the outer wall of one of the support plates, a second frame arranged on the outer wall of the other support plate, a third frame arranged in the first frame and connected to the second frame, and a limiting mechanism arranged outside the first frame. The third frame can horizontally reciprocate in the inner cavity of the first frame, and the position of the third frame is limited by the limiting mechanism.

[0007] Further, the third frame is a hollow square structure. A first limiting portion and a second limiting portion vertically penetrating the third frame are arranged on the third frame. The first limiting portion and the second limiting portion are identical in structure and connected to the limiting mechanism. The first limiting portion and the second limiting portion overlap each other in the top view.

[0008] The first limiting part comprises several wide gap cavities and narrow gap cavities arranged along the length direction of the third frame body, every two wide gap cavities are communicated by a narrow gap cavity, and the inner diameter of the wide gap cavity is larger than that of the narrow gap cavity.

[0009] Further, the limiting mechanism comprises a mounting cylinder arranged outside the first frame body and a limiting pin arranged in the mounting cylinder and capable of cooperating with the first limiting part and the second limiting part; the limiting pin comprises an end head arranged in the mounting cylinder, a first pin column, a second pin column, a third pin column, a fourth pin column, a fifth pin column and an end tail arranged in sequence from the lower end of the end head to the top, and a reset spring sleeved on the first pin column and located below the end head; the outer diameter of the second pin column and the fourth pin column is smaller than that of the third pin column and the fifth pin column, and the outer diameter of the second pin column and the fourth pin column is matched with the narrow gap cavity, the outer diameter of the third pin column and the fifth pin column is matched with the wide gap cavity, and the end tail is exposed outside the first frame body; when the end head is pressed, the second pin column and the fourth pin column move towards the bottom surface of the first frame body and can pass through the narrow gap cavity and the wide gap cavity at the corresponding position, so that the third frame body can move horizontally and reciprocally; when the pressing on the end head is released, after the second pin column and the fourth pin column are driven back by the reset spring, the third pin column and the fifth pin column cooperate with the wide gap cavity at the corresponding position to lock the position of the third frame body.

[0010] Further, the support frame comprises a support main frame and a moving wheel arranged at the lower end of the support main frame.

[0011] Further, the support main frame has an upper frame cavity and a lower frame cavity which are independent of each other, the driving mechanism comprises a driving motor arranged in the upper frame cavity, a screw rod connected with the driving motor and capable of extending into the lower frame cavity, and a moving seat screwed on the screw rod, the support main frame has a moving opening communicated with the lower frame cavity, the connecting part of the support plate is arranged in the moving opening and moves with the moving seat, and the driving motor can drive the moving seat to move reciprocally along the screw rod.

[0012] Further, a sliding groove arranged along the length direction of the support plate is arranged on the side wall of each support plate, and a plurality of connecting pieces are slidably arranged in the sliding groove, and the outer wall of the first frame body and the second frame body is also fixedly connected with a plurality of connecting pieces; a screwing cavity is arranged on the outer wall of each connecting piece, and a fixing screw for fixing the cloth is screwed in the screwing cavity.

[0013] Furthermore, the fabric body has several fabric support ears arranged at intervals along the length of the fabric body on both sides. Each fabric support ear has a through hole for the fixing bolt to pass through. The outer diameter of the head of the fixing bolt is larger than the inner diameter of the through hole. When the fixing bolt is connected in the screw cavity, the fabric support ear is pressed between the head of the fixing bolt and the connector.

[0014] In summary, the beneficial effects of this utility model are as follows: 1. The telescopic rod increases the distance between the two support components, facilitating the adjustment of the support components to both sides of the bed. One end of the fabric is initially not connected to the support component, but is placed between the bed and the patient's body. The fabric is then connected to the corresponding support component. Upon activation of the drive mechanism, all support plates rise synchronously, lifting the patient lying on the fabric off the bed. The patient is then moved to another location (transfer bed, examination bed, or examination table) via wheels. The fabric end can then be separated from the support component, allowing the patient to be transferred to the desired location. Throughout the transfer process, manual handling by medical staff is no longer required, making the transfer operation more automated and easier, reducing the difficulty of transfer, and further minimizing secondary injuries caused by errors. 2. The two support frames in the support component can adjust their distance through a horizontal telescopic structure, allowing for adjustment to accommodate patients of different heights, enhancing versatility. Third, the horizontal telescopic structure can shorten the distance between the two support frames, and the telescopic rod between the two support components can also shorten the distance between them. The soft fabric will not interfere with the adjustment of each support frame. Therefore, this transfer device can also reduce the distance between each support frame, which has the effect of reducing space occupation and thus saving storage space. Attached Figure Description

Detailed Implementation

[0020] The present invention will be further illustrated below with reference to specific figures.

[0021] Please see Figure 1This utility model provides a patient transport device, including two symmetrically spaced support components 100 connected by telescopic rods 200, a foldable fabric body 300 located between the two support components 100 and detachably connected to the corresponding support components 100 at both ends, and a controller disposed within one of the support components 100. The fabric body 300 is preferably made of durable denim. Each support component 100 includes two spaced support frames 110, two drive mechanisms 120 correspondingly disposed within the support frames 110 and electrically connected to the controller, two support plates 130 correspondingly connected to the drive mechanisms 120, and a horizontal telescopic structure 140 connected between the two support plates 130. The drive mechanisms 120 can drive the support plates 130 to reciprocate along the height direction of the support frames 110. Both the support plates 130 and the horizontal telescopic structure 140 are provided with several connectors 400 detachably connected to the fabric body 300. The horizontal telescopic structure 140 is used to adjust the distance between the two support frames 110. Before transferring a patient from the hospital bed to a transport bed, the distance between two symmetrically arranged support components 100 is adjusted using the telescopic rod 200. A wider distance avoids interference with the hospital bed and allows the two support components 100 to be moved smoothly to the sides of the bed. Before transferring the patient, one end of the fabric 300 is detached from one of the support components 100. The fabric 300 is then placed under the patient's body and connected to the corresponding support component 100. The controller allows all support plates 130 to move synchronously. The support plates 130 in the drive mechanism 120 are raised, directly lifting the patient for transport. The support component 100 has two support frames 110, and the distance between the two support frames 110 on the same side is adjustable, thus allowing for adjustment of the length of the support component 100 to accommodate patients of different heights. When transferring the patient to the transport bed or examination bed, medical staff are no longer needed to assist in the transfer, saving manpower and reducing the difficulty of transport. Furthermore, the automated transport reduces the chance of errors and minimizes secondary injury to the patient.

[0022] The two support assemblies 100 each have four support frames 110, each including a main support frame 111 and casters 112 located at the lower end of the main support frame 111. The support frames 110 provide stable and secure support at their four corners, and every two support frames 110 on different sides but corresponding in position are connected by a telescopic rod 200. The casters 112 facilitate transport and movement, making it easier and more convenient to transfer immobile patients.

[0023] The main support frame 111 has two independent upper frame cavity 111A and lower frame cavity 111B. Please refer to [link / reference]. Figure 2The drive mechanism 120 includes a drive motor 121 installed in the upper shelf cavity 111A, a screw 122 connected to the drive motor 121 and capable of extending into the lower shelf cavity 111B, and a movable seat 123 screwed onto the screw 122. The main support frame 111 has a movable opening 1110 communicating with the lower shelf cavity 111B. The connecting part of the support plate 130 passes through the movable opening 1110 and moves with the movable seat 123. The drive motor 121 can drive the movable seat 123 to reciprocate along the screw 122. When the drive motor 121 is started, it drives the screw 122 to rotate, so that the movable seat 123 can reciprocate within the lower shelf cavity 111B. The support plate 130 connected to the movable seat 123 can reciprocate along the movable opening 1110 (i.e., move up and down along the support frame 110), thereby enabling the patient lying on the cloth body 300 to move up and down, automatically transferring the patient from one position to another, saving manpower and making operation easy.

[0024] The horizontal telescopic structure 140 includes a first frame 141 disposed on the outer wall of one of the support plates 130, a second frame 142 disposed on the outer wall of the other support plate 130, a third frame 143 passing through the first frame 141 and connected to the second frame 142, and a limiting mechanism 145 disposed outside the first frame 141. The third frame 143 can move horizontally back and forth within the cavity of the first frame 141, and its position is limited by the limiting mechanism 145. The fabric 300 can be folded or unfolded. The distance between the two support frames 110 on the same side needs to be adjusted according to the patient's height. The third frame 143 is stretched out from the cavity of the first frame 141, increasing the distance between the two support frames 110. The lengths of the two support components 100 can be adjusted to fit the patient's body shape, and the fabric 300 can be unfolded arbitrarily for adaptation, making it more versatile and practical.

[0025] Each support plate 130 has a sliding groove 131 arranged along the length of the support plate 130 on its side wall, and several connectors 400 are slidably installed in the sliding groove 131. Several connectors 400 are also fixed to the outer walls of the first frame 141 and the second frame 142. Each connector 400 has a threaded cavity on its outer wall, and a fixing bolt 500 for fixing the fabric body 300 is screwed into the threaded cavity. Several fabric lugs 310 are provided on both sides of the fabric body 300, arranged at intervals along the length of the fabric body 300. Each fabric lug 310 has a through hole for the fixing bolt 500 to pass through. The outer diameter of the head of the fixing bolt 500 is larger than the inner diameter of the through hole. When the fixing bolt 500 is connected in the threaded cavity, the fabric lug 310 is pressed between the head of the fixing bolt 500 and the connector 400. The connector 400 connected to the support plate 130 can slide and move, so as to facilitate the adjustment of the position and the connection with the cloth support ear 310. When the cloth body 300 is folded or unfolded, the corresponding connector 400 can be selected for connection according to the actual situation. After the fixing bolt 500 passes through the through hole, it is screwed to the connector 400, so as to firmly fix the cloth body 300. Moreover, the disassembly and assembly are very simple and convenient, and the operation is easy.

[0026] The third frame 143 is a hollow square structure. A first limiting part 1430 and a second limiting part are vertically penetrating the third frame 143. The first limiting part 1430 and the second limiting part have identical structures and are both connected to the limiting mechanism 145. In a top-view orthographic projection, the first limiting part 1430 and the second limiting part overlap, making them easier to manufacture. (See also...) Figure 3 The first limiting part 1430 includes a plurality of wide-gap cavities 1430A and narrow-gap cavities 1430B spaced apart along the length of the third frame 143. Each pair of wide-gap cavities 1430A is connected by a narrow-gap cavity 1430B, and the inner diameter of the wide-gap cavity 1430A is larger than the inner diameter of the narrow-gap cavity 1430B. (See also...) Figure 4The limiting mechanism 145 includes a mounting cylinder 1450 located outside the first frame 141 and a limiting pin installed inside the mounting cylinder 1450 and capable of cooperating with the first limiting part 1430 and the second limiting part. The limiting pin includes an end head 1451 disposed inside the mounting cylinder 1450, a first pin 1452, a second pin 1453, a third pin 1454, a fourth pin 1455, a fifth pin 1456 and an end tail 1457 fixed to the lower end of the end head 1451 and arranged sequentially from top to bottom, and a return spring 1458 sleeved inside the first pin 1452 and located below the end head 1451. The outer diameters of the second pin 1453 and the fourth pin 1455 are smaller than the outer diameters of the third pin 1454 and the fifth pin 1456. The outer diameters of the second pin 1453 and the fourth pin 1455 are adapted to the narrow gap cavity 1430B, and the outer diameters of the third pin 1454 and the fifth pin 1456 are adapted to the wide gap cavity 1430A. The end tail 1457 is exposed outside the first frame 141. When the second pin 1453 and the fourth pin 1455 of the pressing end head 1451 move toward the bottom surface of the first frame 141 and can pass through the narrow gap cavity 1430B and the wide gap cavity 1430A at the corresponding positions, the third frame 143 can move horizontally back and forth. When the pressing of the pressing end head 1451 is released, the return spring 1458 drives the second pin 1453 and the fourth pin 1455 to return to their original positions, and the third pin 1454 and the fifth pin 1456 cooperate with the wide gap cavity 1430A at the corresponding position to lock the position of the third frame 143.

[0027] When adjusting the distance between the two support frames 110 using the above-mentioned horizontal telescopic structure 140, press the limiting pin and press the end head 1451 towards the depth of the mounting cylinder 1450. The return spring 1458 is in a compressed state, and the end tail 1457 moves away from the first frame 141. At this time, the second pin 1453 and the fourth pin 1455, which have smaller outer diameters and can pass through both the narrow gap cavity 1430B and the wide gap cavity 1430A, both descend to the corresponding position of the wide gap cavity 1430A. Since the second pin 1453 and the fourth pin 1455 can pass through both the wide gap cavity 1430A and the narrow gap cavity 1430B, the third frame 143 can be smoothly moved back and forth in the inner cavity of the first frame 141 in this state. After completing the telescopic adjustment, release the pressure on the end head 1451, and the return spring 1458 returns to its original position. At this time, the second pin 1453 and the fourth pin 1455 move back to their original positions along the height direction of the third frame 143. The third pin 1454 and the fifth pin 1456, with larger outer diameters, return to their corresponding positions in the wide-gap cavity 1430A. While the outer diameters of the third pin 1454 and the fifth pin 1456 are insufficient to pass through the narrow-gap cavity 1430B, they can fit into the wide-gap cavity 1430A. Therefore, the movement of the third frame 143 can be prevented, thus limiting the position of the third frame 143. Adjusting the third frame 143 and limiting its position is simple to operate, allowing the support frame 110 to be quickly adjusted to the appropriate position.

[0028] This transfer device: 1. A telescopic rod 200 increases the distance between the two support components 100, facilitating the adjustment of the support components 100 to the sides of the bed. One end of the fabric 300 is initially not connected to the support component 100, but is placed between the bed and the patient's body. The fabric 300 is then connected to the corresponding support component 100. After activating the drive mechanism 120, all support plates 130 rise synchronously, lifting the patient lying on the fabric 300 off the bed. The patient is then moved to another location (transfer bed, examination bed, or examination table) via the moving wheels 112. The fabric 300 is then detached from the support component 100, allowing the patient to be transferred to the desired location. Throughout the transfer process, manual handling by medical staff is no longer required, making the transfer operation more automated and easier, reducing the difficulty of transfer, and further minimizing secondary injuries caused by errors. 2. The two support frames 110 in the support component 100 can be adjusted in distance via a horizontal telescopic structure 140, allowing for adjustment to accommodate patients of different heights, enhancing versatility. Third, the horizontal telescopic structure 140 can shorten the distance between the two support frames 110, and the distance between the two support components 100 can also be shortened by the telescopic rod 200. The soft cloth 300 will not interfere with the adjustment of each support frame 110. Therefore, this transfer device can also reduce the distance between each support frame, which has the effect of reducing space occupation and thus saving storage space.

[0029] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structure made using the contents of this utility model specification and drawings, whether directly or indirectly applied to other related technical fields, shall also be within the patent protection scope of this utility model.
