Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically a folding stretcher. Background Technology

[0002] Stretchers are simple in structure and low in cost, making them an indispensable tool for emergency calls and patient transport. However, medical personnel have found that existing stretchers are not very effective at securing the patient during transport. They typically use two safety belts to secure the patient, but the contact area between the belts and the patient is small. This only prevents the patient from falling off the stretcher, and the patient's legs and arms can easily swing off the stretcher, causing secondary injuries. The lack of stable and comprehensive fixation also creates problems for emergency personnel. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 This utility model provides a technical solution: a folding stretcher, including a stretcher cloth 1 and U-shaped frames 2 fixed to the front and rear sides of the outer surface of the stretcher cloth 1. Side wings 3 are fixedly connected to the left and right sides of the outer surface of the stretcher cloth 1. The two sets of U-shaped frames 2 are hinged by two sets of connecting mechanisms 4. Three sets of safety belts 5 are fixedly connected to the lower surface of the stretcher cloth 1 and the side wings 3. A hollow hole 501 is opened in the middle of the outer surface of the safety belt 5 located in the middle. The hollow hole 501 is designed to prevent the safety belt 5 from being excessively squeezed and folded after the U-shaped frame 2 is folded. Both sides of the outer surface of the stretcher fabric 5 are equipped with buckles 6. The buckles are metal quick-opening snap fasteners for easy use. A headrest 7 is provided on the front side of the upper surface of the stretcher fabric 1. The headrest 7 includes a headrest fabric 701. The right side of the lower surface of the headrest fabric 701 is sewn to the stretcher fabric 1. Seven sets of snap fasteners 702 are provided between the headrest fabric 701 and the stretcher fabric 1. A rainproof cloth 703 is provided on the inner side of the headrest fabric 701. The headrest fabric 701 is fixed on one side and can be opened on three sides, which is convenient for emergency personnel to take out and put in the rainproof cloth 703. The headrest fabric 701 is secured on one side and can be opened on the other three sides. The rainproof cloth 703 is connected by side wings 3, safety belt 5, and buckles. When used in conjunction with the hand straps 11, after the person being transported is laid on the stretcher sheet 1, the emergency personnel can wrap the side wings 3 around the sides of the person's body and secure the safety belts 5 together using the buckles 6. The length of the safety belts 5 can be adjusted, allowing the device to provide comprehensive wrapping and securing to the sides of the person's body, preventing their legs and arms from being thrown off the stretcher. Furthermore, if the person being transported is conscious, they can hold onto the hand straps 11 themselves. This design enhances the stability of the stretcher during transport. The headrest cloth 701, snap fasteners 702, and rainproof cloth 703 work together to allow the person being transported to rest their head on the headrest 701, improving their comfort. In case of rain, emergency personnel can open the snap fasteners 702, unfold the headrest cloth 701, and take out the rainproof cloth 703 to place on the person being transported. The rainproof cloth 703 is then secured by the side wings 3, making the device portable and rainproof, thus enriching its functionality.

[0023] In this invention, in order to achieve unidirectional folding of the U-shaped frame 2, a semi-circular locking block 401 is provided. Two sets of pins 402 are rotatably connected to the outer surface of the semi-circular locking block 401. The inner end of the U-shaped frame 2 is provided with a locking groove 201 that matches the semi-circular locking block 401, so that the U-shaped frame 2 can only be folded in the reverse direction. When the U-shaped frame 2 is unfolded 180 degrees, the semi-circular locking block 401 will contact and lock with the locking groove 201, thereby realizing unidirectional folding of the U-shaped frame 2.

[0024] In this invention, to facilitate the storage and placement of the device, a rectangular hook 8 is rotatably connected to the front side of the outer surface of the U-shaped frame 2 located on the front side, and a locking block 9 is fixedly connected to the rear side of the outer surface of the U-shaped frame 2 located on the rear side. The outer surface of the locking block 9 has a locking groove that matches the rectangular hook 8, so that the U-shaped frame 2 can be fixed to the locking block 9 by the rectangular hook 8 after folding, preventing the U-shaped frame 2 from being accidentally unfolded, thereby facilitating the storage and placement of the device.

[0025] In this utility model, in order to further improve the comfort of emergency personnel carrying the stretcher, a canvas handle 10 is fixedly connected to the outer side of the outer surface of the U-shaped frame 2, and a hand grip strap 11 is fixedly connected to the middle of the lower surface of the side wing 3, so that emergency personnel can lift the device through the canvas handle 10, thereby further improving the comfort of emergency personnel carrying the stretcher.

[0026] In this invention, in order to further reduce the overall weight of the stretcher, the U-shaped frame 2 is made of aviation aluminum alloy and the outer surface of the U-shaped frame 2 is anodized. By setting the material of the U-shaped frame 2, the overall weight of the stretcher is further reduced, the structural strength of the overall frame is guaranteed, and the rust resistance is improved.

[0027] In this invention, in order to further improve the wear resistance and waterproof performance of the stretcher, both the stretcher cloth 1 and the side wings 3 are made of Oxford cloth, and both the stretcher cloth 1 and the side wings 3 are one millimeter thick. By setting the materials of the stretcher cloth 1 and the side wings 3, the wear resistance and waterproof performance of the stretcher are further improved.

[0028] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that can control it.

[0029] When in use, unfold the two sets of U-shaped frames 2, place the person to be transferred on the stretcher cloth 1. In case of rain or snow, open the snap fasteners 702, unfold the headrest cloth 701, take out the rainproof cloth 703 and lay it on the person to be transferred, wrap the side wings 3 around the left and right sides of the person to be transferred, insert the buckles 6 on the left and right sides, tighten the far end of the right side safety belt 5, so that the safety belt 5 and the side wings 3 fix the person to be transferred, thus completing the fixation of the person to be transferred. If the person to be transferred is conscious, they can hold the handle straps 11 with their hands and lift the stretcher to move it through the canvas handles 10. After use, fold the rainproof cloth 703 and stuff it into the headrest cloth 701, press the snap fasteners 702 to fix the headrest cloth 701, fold the two sets of U-shaped frames 2 in the opposite direction, and lock the rectangular hooks 8 into the slots on the clips 9, thus completing the folding and storage of the stretcher.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
