Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a nursing stretcher. Background Technology

[0002] Stretchers, as the most commonly used patient transfer tool in hospitals, are widely used in the transport of bedridden patients. Traditional transport methods rely on nursing staff manually lifting the patient from the bed and transferring them horizontally onto the stretcher, then multiple people working together to lift the stretcher for transport; upon arrival at the destination bed, the patient must be lifted back from the stretcher to the bed. This process has significant drawbacks:

[0003] First, the repeated manual lifting and carrying operations greatly increase the labor intensity of nursing staff. A single transfer requires multiple people, which is inefficient and has high labor costs.

[0004] Secondly, during the process of carrying the patient, the patient's body is forced to bend, which can easily cause secondary injury to patients with spinal injuries or those recovering from surgery, aggravating their physical pain and psychological panic. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a nursing stretcher to solve the problems mentioned above in the background art.

[0006] A nursing stretcher includes a frame and a bed frame mounted on the frame via a connecting structure. A buffer space is formed between the frame and the bed frame. The connecting structure includes a support portion fixed to the frame, a limiting groove formed at the top of the support portion, a limiting portion fixed to the bed frame and adapted to the limiting groove, and fixing portions movably mounted on the bed frame at both ends of the limiting portions. After the limiting portions are inserted into the limiting groove, both fixing portions can move toward the support portion and simultaneously compress both sides of the support portion.

[0007] Compared to existing technologies, the advantages of this application are as follows: The stretcher is moved as a whole to the side of the bed or testing equipment. The two fixing parts are rotated in the opposite direction to release their pressure on the support, allowing the limiting parts to disengage. The bed frame is then lifted upwards, and the patient is lifted synchronously with the bed frame. Nursing staff can directly hold the bed frame and move the patient to the target position (bed / testing table). When it is necessary to leave the target position and return to the corresponding frame, the limiting part of the bed frame is aligned with the limiting slot of the frame and inserted. The bed frame is then supported on the frame. The two fixing parts are then rotated synchronously to the locking position, causing the ends of the fixing parts to press against the sides of the support, forming a bidirectional locking force. This locks the bed frame onto the frame, and the stretcher is then moved to the corresponding position. In summary, patient transfer and fixation can be completed simply by operating the bed frame, shortening the transfer time, increasing efficiency, and reducing labor costs.

[0008] Furthermore, the frame includes a first support frame formed by multiple first support rods and a pulley connected to the bottom of the first support frame, and the support part is fixed to the first support rod.

[0009] Furthermore, the bed frame includes a second support frame formed by multiple second support rods, and the limiting part is coaxially arranged with the second support rods.

[0010] Furthermore, the bed frame extends to both ends with lifting frames, each lifting frame including two connecting rods fixed to the bed frame and a lifting rod connecting the two connecting rods. The two ends of the lifting rod are connected to the ends of the two connecting rods by a hinge structure, and the hinge structure is located at the bottom of the lifting rod, so that when the lifting rod is rotated upward around the hinge axis, the end of the lifting rod presses against the end of the connecting rod.

[0011] Furthermore, the top of the bed frame extends with multiple limiting plates, which together form a limiting space for limiting the mattress.

[0012] Furthermore, the limiting plate has limiting holes for installing constraint straps.

[0013] Furthermore, the fixing part is a rotating nut, whose rotation axis is parallel to the length direction of the limiting part. When the fixing part is rotated, the end of the rotating nut presses against the side of the support.

[0014] Furthermore, the sidewall of the fixing part extends outward with multiple operating handles. Attached Figure Description

Several embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this utility model will be more thorough and complete.

[0024] It should be noted that when a component is said to be "fixed to" another component, it can be directly on the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0026] Please see Figure 1 and Figure 6The image shows a nursing stretcher according to an embodiment of the present invention, comprising: a frame 10 and a bed frame 30 disposed on the frame 10 via a connecting structure 20. A buffer space 33 is formed between the frame 10 and the bed frame 30. The connecting structure 20 includes a support portion 21 fixed to the frame 10, a limiting groove 22 formed at the top of the support portion 21, a limiting portion 23 fixed to the bed frame 30 and adapted to the limiting groove 22, and fixing portions 24 movably disposed on the bed frame 30 and at both ends of the limiting portion 23. After the limiting portion 23 is inserted into the limiting groove 22, both fixing portions 24 can move toward the support portion 21 and simultaneously compress both sides of the support portion 21.

[0027] It is worth noting that the stretcher is moved to the side of the bed or testing equipment. The two fixing parts 24 are rotated in the opposite direction to release their pressure on the support part 21, allowing the limiting part 23 to disengage. The bed frame 30 is then lifted upwards, and the patient is lifted synchronously with the bed frame 30. The nursing staff directly holds the bed frame 30 and moves the patient to the target position (bed / testing table). When it is necessary to leave the target position and return to the corresponding frame 10, the limiting part 23 of the bed frame 30 is aligned with the limiting groove 22 of the frame 10 and inserted. The bed frame 30 is then supported on the frame 10. The two fixing parts 24 are then rotated synchronously to the locking position, causing the ends of the fixing parts 24 to press against both sides of the support part 21, forming a bidirectional locking force. This limits the bed frame 30 to the frame 10, and the stretcher is then moved to the corresponding position. In summary, only the bed frame 30 needs to be operated to transfer and fix the patient in place, shortening the transfer time, increasing efficiency, and reducing labor costs.

[0028] The buffer space 33 formed between the frame 10 and the bed frame 30, combined with the synchronous compression of the support part 21 by the bidirectional movable fixing part 24, effectively absorbs the impact force during the overall transport of the stretcher, significantly reducing the discomfort caused by the patient's jolting. After the limiting part 23 is inserted into the limiting groove 22, the two fixing parts 24 move and compress towards both sides of the support part 21 simultaneously, forming a symmetrical locking force, completely avoiding the eccentric swaying caused by unilateral fixation, and improving the overall structural rigidity of the stretcher.

[0029] Please see Figure 7 Specifically, the frame 10 includes a first support frame 12 formed by multiple first support rods 11 and pulleys 13 connected to the bottom of the first support frame 12. The support part 21 is fixed to the first support rods 11. The first support frame 12 provides a stable bearing surface, and the pulleys 13 enable flexible movement.

[0030] Specifically, the bed frame 30 includes a second support frame 32 formed by multiple second support rods 31, and the limiting part 23 is coaxially arranged with the second support rods 31.

[0031] Furthermore, the bed frame 30 has lifting frames 40 extending from both ends. Each lifting frame 40 includes two connecting rods 41 fixed to the bed frame 30 and a lifting rod 42 connecting the two connecting rods 41. The two ends of the lifting rod 42 are connected to the ends of the two connecting rods 41 via a hinge structure 43, which is located at the bottom of the lifting rod 42. When the lifting rod 42 is flipped upwards around the hinge axis, the end of the lifting rod 42 presses against the end of the connecting rod 41. The lifting rod 42 can be folded downwards for storage, preventing tripping during transport; after being returned to its original position, it can be used directly as a lifting arm without disassembly. In this embodiment, the hinge structure 43 includes rotating seats connected to the lifting rod 42 and the connecting rod 41 respectively, and rotating pins connected to the two rotating seats. The rotating seats can rotate around the rotating pins.

[0032] Furthermore, the top of the bed frame 30 extends with multiple limiting plates 34, which together form a limiting space for limiting the mattress 36. This prevents the mattress 36 from shifting or curling during bumps, ensuring the stability of the patient while lying down.

[0033] Furthermore, the limiting plate 34 has limiting holes 35 for installing restraint straps. Fixing the restraint straps through the limiting holes 35 facilitates the restraint of the patient on the stretcher.

[0034] Specifically, the fixing part 24 is a rotating nut, whose rotation axis is parallel to the length direction of the limiting part 23. When the fixing part 24 is rotated, the end of the rotating nut presses against the side of the support.

[0035] Multiple operating handles 241 extend outward from the side wall of the fixing part 24. The fixing part 24 can be rotated by turning the operating handles 241.

[0036] In summary, the working principle of the nursing stretcher in the above embodiments of this utility model;

[0037] Release the brake on pulley 13 and push the stretcher to the side of the bed or testing equipment. Rotate the two fixing parts 24 in the opposite direction to release their pressure on the support part 21, allowing the limiting part 23 to disengage from its limiting constraint. Flip the lifting rod 42 upwards; the end of the lifting rod 42 presses against the end of the connecting rod 41 through the top hinge structure 43, thus lifting the bed frame 30 as a whole. At this time, the patient is lifted synchronously with the bed frame 30, and the nursing staff directly holds the lifting rod 42 to move the patient to the target position. When it is necessary to return to the corresponding frame 10, align the limiting part 23 of the bed frame 30 with the limiting groove 22 of the frame 10 and insert it. Then, rotate the two fixing parts 24 synchronously to the locking position, so that the ends of the fixing parts 24 press against both sides of the support part 21, forming a two-way locking force. Place the mattress 36 in the limiting space at the top of the bed frame 30. The patient transfer and fixation can be completed by simply operating the bed frame 30, shortening the transfer time.
