Description

Technical Field

[0001] This utility model relates to the field of medical devices and equipment, specifically a foldable stretcher fixing device for use in scenarios such as medical transport, emergency rescue, and disaster sites, to securely and reliably fix the stretcher. Background Technology

[0002] As is well known, stretchers are crucial tools for transporting patients or the injured in medical rescue and disaster relief operations, and their secure fixing is of paramount importance. This is especially true when multiple patients need to be transported simultaneously, where the issue of securing multiple stretchers becomes particularly prominent. Currently, in scenarios involving the simultaneous transport of multiple stretchers, they are typically simply placed on the transport equipment. This not only takes up a large area but also lacks effective connection and securing measures, resulting in unstable relative positions between the stretchers. Under conditions of vehicle bumps or helicopter swaying, stretchers are prone to colliding with each other, potentially causing secondary injuries to the patients on them. Furthermore, some existing stretcher securing devices are cumbersome to operate, requiring considerable time for installation and adjustment, causing delays; moreover, most existing stretcher securing devices lack folding capabilities, occupying significant space when not in use, which is inconvenient for storage and transportation. Summary of the Invention

[0003] To overcome the shortcomings of existing stretcher fixation devices in terms of fixation effect and space occupation, this utility model provides a foldable stretcher fixation device that is easy to operate, reliable in fixation, and occupies little space, thereby improving the safety and efficiency of the transfer process.

[0004] The technical solution adopted by this utility model to solve its technical problem is as follows: a foldable stretcher fixing device, characterized in that the supporting crossbar is welded to the lower end of an H-shaped bracket, and a rotating fixing device 1 and a rotating fixing device 2 are respectively fitted on the left and right ends of the supporting crossbar. A locking pin is installed on the rotating fixing device 2. A stretcher locking device 1 and a stretcher locking device 2 are respectively fixed on the left and right sides of the lower part of the H-shaped bracket. A stretcher locking device 1 and a stretcher locking device 2 are also respectively fixed on the left and right sides of the upper part of the H-shaped bracket. A semi-circular stretcher support base 1 of the stretcher locking device 1 is hinged to a semi-circular upper cover block 1 via a pivot. A locking device capable of locking the upper cover block 1 is installed on the stretcher support base 1, and a handle is installed on the locking device. A semi-circular stretcher support base 2 of the stretcher locking device 2 is hinged to a semi-circular upper cover block 2 via a pivot. A locking device capable of locking the upper cover block 2 is installed on the stretcher support base 2, and a handle is installed on the locking device.

[0005] A rubber plate is installed on the inner side of the upper cover block and the stretcher support base.

[0006] A rubber plate is installed on the inner side of the upper cover block 2 and the stretcher support base 2.

[0007] The advantages of this utility model are that it can be quickly folded and stored when not in use, taking up little space; the stretcher locking device adopts a handle locking mechanism, which is convenient to operate, reliable in locking, and has a short locking and unlocking time; each pair of stretcher fixing devices can simultaneously place two sets of stretchers on top of each other.

[0017] In the figure, this utility model is provided with a supporting crossbar 3, which is welded to the lower end of the H-shaped bracket 19. The left and right ends of the supporting crossbar 3 are respectively fitted with a circular rotating fixing device 1 and a rotating fixing device 2 5, which are rotatably fitted. The circular rotating fixing device 1 and rotating fixing device 2 5 are fixed to the mounting surface. A locking pin 9 is installed on the rotating fixing device 2 5. A stretcher locking device 1 2 and a stretcher locking device 2 4 are respectively fixed to the left and right sides of the lower part of the H-shaped bracket 19. A stretcher locking device 1 and a stretcher locking device 2 are also respectively fixed to the left and right sides of the upper part of the H-shaped bracket 19. The stretcher locking device 1 2 has a semi-circular stretcher support base 1. 2. A semi-circular upper cover block 11 is hinged to a pivot 10. A locking device 14 capable of locking the upper cover block 11 is installed on the stretcher support base 12. A handle 18 is installed on the locking device 14. A rubber plate 13 is installed on the inner side of the upper cover block 11 and the stretcher support base 12. A semi-circular stretcher support base 15 of the stretcher locking device 2 is hinged to a semi-circular upper cover block 17 via a pivot 10. A rubber plate 16 is installed on the inner side of the upper cover block 17 and the stretcher support base 15. A locking device 14 capable of locking the upper cover block 17 is also installed on the stretcher support base 15. A handle 18 is installed on the locking device 14.

[0018] When this utility model is used, Figure 2 As shown, the stretcher fixing device needs to be used in pairs, and each pair of stretcher fixing devices can simultaneously place two stretchers 8 one above the other. Fix the rotating fixing device 1 and the rotating fixing device 2 5 to the mounting surface. According to the length of the general stretcher GJB831 of 2200mm, the installation distance A should preferably be between 1850mm and 2000mm.

[0019] like Figure 3 As shown, after installation, the two flat stretcher fixing devices are erected one by one. Before erecting, the locking pin 9 on the stretcher fixing device is pulled up, rotated 90° clockwise and counterclockwise and then lowered to make the locking pin 9 in the unlocked state. The H-shaped bracket 19 is erected, the locking pin 9 is pulled up and rotated 90° counterclockwise and counterclockwise and then lowered to make the locking pin 9 return to the locked state and the stretcher fixing device is unfolded.

[0020] like Figure 6 , 7As shown, when placing the bottom stretcher 8, first rotate the two stretcher locking devices 1-2 and 2-4 at the top of the H-shaped support 19 to the inside of the H-shaped support 19. Then, pull out the handles 18 on the locking devices 14 of the bottom stretcher locking devices 1-2 and 2-4 in sequence, causing the upper cover blocks 1-11 and 2-17 to flip open and place the stretcher 8 inside. After the bottom stretcher 8 is placed, flip and press the upper cover blocks 1-11 and 2-17 to reset the handles 18 on the locking devices 14. The stretcher poles are locked and fixed, and the bottom stretcher is secured. Rotate the two stretcher locking devices 1-2 and 2-4 at the top of the H-shaped support 19 to the outside of the H-shaped support 19 and place the upper stretcher. The steps for securing the upper stretcher are the same as those for securing the lower stretcher. The locking and unlocking actions at either end of the stretcher pole can be completed within 5 seconds, resulting in a short deployment and retraction time.

[0021] The withdrawal action is the reverse process of the above actions.
