Description

Technical Field

[0001] This utility model relates to the field of stretcher technology, specifically to a multifunctional stretcher for quick fixation and transfer. Background Technology

[0002] Existing stretchers are usually carried by two people, one in front and one behind. The injured or sick person lies on the stretcher without any guardrails around them. If the person carrying the stretcher loses their balance, the stretcher can easily tilt, causing the injured or sick person to fall off. Moreover, existing stretchers require two people to lift them. When there is only one person, it is impossible to transfer the injured or sick person. Most stretchers on the market are not equipped with restraint belts. The injured or sick person lies on the stretcher without any restraint. When encountering rough or bumpy roads during the movement, the risk of the injured or sick person slipping off the stretcher is very high.

[0003] A search revealed that patent CN201520417390.2 discloses a multi-functional stretcher. While this device utilizes a boat-shaped plastic stretcher body with several perforations on its four side walls, and includes a rope that passes through these perforations and is then tied together at one end of the stretcher body, with a rough front and smooth back, and handles on both sides, along with several sets of restraint straps along its width, this multi-functional stretcher allows for patient transfer by a single person and improves patient safety. It can also be used to lift and transfer patients by helicopter. However, the device suffers from several drawbacks: the support plate cannot be used independently, and it lacks support blocks, resulting in insufficient stability during cleaning, maintenance, or temporary placement. This makes it difficult to meet diverse rescue needs. Furthermore, the lack of auxiliary movement devices, relying solely on manual handling or helicopter transport, makes it inflexible in narrow passages, stairwells, or confined indoor spaces, hindering rapid position adjustments. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a multifunctional stretcher for rapid fixation and transfer, solving the problems mentioned in the background art.

[0005] The solution to the above-mentioned technical problems provided by this utility model is as follows:

[0006] A multifunctional stretcher for quick fixation and transfer includes a bracket on which a tray is placed;

[0007] The bracket has a first support rod and a second support rod at its bottom end, and a support is provided at the bottom end of the bracket. The support has a sliding wheel at its bottom end, and a fixed shaft is provided on the support. A first connecting rod and a second connecting rod are connected to the fixed shaft, and the first connecting rod and the second connecting rod are rotatably connected to the second support rod and the first support rod, respectively.

[0008] The pallet is equipped with a limiting headrest, and the outer side of the pallet is equipped with a surrounding plate with straps. The bottom end of the pallet is equipped with a fixing clip. The pallet is interlocked with the second support rod through the fixing clip, thereby allowing the pallet to be interlocked and installed on the bracket.

[0009] Based on the above technical solution, the present invention can be further improved as follows.

[0010] Furthermore, the second link is provided with a folding joint, and the second link is folded through the folding joint, thereby folding the bracket and storing it at the bottom of the bracket.

[0011] The beneficial effects of adopting the above-mentioned further solutions are:

[0012] This significantly improves the portability and storage convenience of the stretcher. When not in use, the support frame can be compactly folded and stored at the bottom of the bracket, greatly reducing the overall space occupied by the stretcher. This allows for the placement of more essential emergency equipment in the limited storage space of ambulances; in the complex environment of a rescue scene, it facilitates quick storage and transport of the stretcher by rescue personnel, saving space and manpower, and enabling rapid response to various emergencies.

[0013] Furthermore, the bottom end of the tray is provided with a support block, and the fixing clips are distributed intersectingly with the support block. When the tray is not assembled with the bracket, the tray is supported on the ground by the support block.

[0014] The beneficial effects of adopting the above-mentioned further solutions are:

[0015] When the tray is used alone, the support blocks provide stable support. The cross-shaped structural design, based on mechanical principles, ensures more even force distribution and greater stability when the tray is placed on the ground, preventing tilting or tipping due to instability and ensuring patient safety. Furthermore, this independent support design provides great convenience when the tray needs to be operated independently, such as for cleaning, maintenance, or temporary placement of items.

[0016] Furthermore, the first connecting rod is provided with an auxiliary wheel, and the bracket is folded and stored so that the auxiliary wheel on the first connecting rod is in contact with the ground.

[0017] The beneficial effects of adopting the above-mentioned further solutions are:

[0018] With the stretcher folded and stowed, the auxiliary wheels contact the ground, giving it excellent mobility. Whether navigating narrow passages, turning corners on stairs, or in confined indoor spaces, rescuers can easily push the stretcher and flexibly change its position. Simultaneously, when the stretcher is unfolded, the auxiliary wheels also provide additional support, distributing some of the weight of the stretcher and patient based on the principles of leverage and force decomposition, improving the overall stability of the stretcher, reducing swaying caused by uneven ground or uneven pushing force, and ensuring a smooth and safe patient transport.

[0019] Furthermore, two fixing clips form a group, and multiple groups of fixing clips are evenly distributed on the bottom surface of the tray, with the positions of the fixing clips corresponding to the positions of the second support rods.

[0020] The beneficial effects of adopting the above-mentioned further solutions are:

[0021] Multiple sets of evenly distributed fixing clips can fully cooperate with the second support rod to securely fasten the pallet from multiple positions. This makes the pallet more firmly and reliably fixed on the stretcher, effectively preventing the pallet from shaking, shifting, or even falling off during transport, regardless of the bumpy road conditions encountered. This comprehensively ensures the patient's safety on the stretcher and provides a solid and stable support platform for patient transport.

[0022] This utility model provides a multifunctional stretcher for quick fixation and transfer. It has the following features:

[0023] Beneficial effects:

[0024] The stretcher can be folded and stored at the bottom of the bracket via a folding joint on the second link, facilitating storage and transportation and reducing space occupation. This is especially suitable for environments with limited space, such as emergency vehicles and rescue sites. It is equipped with sliding wheels for quick transport on flat surfaces, and auxiliary wheels are also provided on the first link. When the stretcher is folded and stored, the auxiliary wheels are in contact with the ground, further facilitating movement of the stretcher in its folded state. Furthermore, when the stretcher is unfolded, the auxiliary wheels provide additional support and balance, improving the overall stability of the stretcher.

[0025] The tray is secured to the second support rod via a fixing clip, ensuring a stable installation on the bracket and preventing it from easily shaking or falling off during transport, thus guaranteeing patient safety. The fixing clips and support blocks at the bottom of the tray are arranged in a crisscross pattern. When the tray is not assembled with the bracket, the support blocks provide stable support on the ground. This crisscross structure further enhances the overall stability of the structure after the tray is assembled with the bracket.

[0026] The stretcher is equipped with a headrest to secure and limit the patient's head, preventing secondary injury caused by head movement during transport and improving the patient's safety and comfort. Straps are located on the outer side panels of the stretcher to secure the patient to the stretcher, preventing slippage and further ensuring patient safety during transport.

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.

[0035] Please see Figures 1 to 3 As shown, the embodiments provided by this utility model are as follows:

[0036] Example 1

[0037] A multifunctional stretcher for rapid fixation and transport includes a bracket 1 with a tray 9 placed on it. The bottom end of the bracket 1 has a first support rod 10 and a second support rod 11, and a support 7 with sliding wheels 3. A fixed shaft 4 is mounted on the support 7, and a first connecting rod 6 and a second connecting rod 8 are connected to the fixed shaft 4. The first connecting rod 6 and the second connecting rod 8 are rotatably connected to the second support rod 11 and the first support rod 10, respectively. The second connecting rod 8 has a folding joint 5, which folds the second connecting rod 8, allowing the support 7 to be folded and stored at the bottom of the bracket 1, greatly improving the stretcher's portability and storage convenience. When the stretcher is not in use, the support 7 can be compactly folded and stored at the bottom of the bracket 1, significantly reducing the overall space occupied by the stretcher. This design allows for the placement of more essential emergency equipment within the limited storage space of ambulances. In complex rescue environments, it facilitates quick storage and transport of the stretcher by rescue personnel, saving space and manpower, and enabling rapid response to various emergencies. The first link 6 is equipped with auxiliary wheels 2. When the support 7 is folded down, the auxiliary wheels 2 on the first link 6 contact the ground, providing excellent mobility for the stretcher. Whether navigating narrow passages, turning corners on stairs, or in confined indoor environments, rescue personnel can easily push the stretcher and flexibly change its position. Simultaneously, when the stretcher is unfolded, the auxiliary wheels 2 also provide auxiliary support, distributing some of the weight of the stretcher and patient based on the principles of leverage and force decomposition, improving the overall stability of the stretcher, reducing swaying caused by uneven ground or uneven pushing force, and ensuring a smooth and safe patient transport process.

[0038] Example 2

[0039] To facilitate the installation of the tray 9 on the bracket 1, for example, such as Figures 1 to 3As shown, this utility model also includes: a limiting headrest 902 on the tray 9, and a surrounding plate on the outer side of the tray 9, with a strap 901 on the surrounding plate, and a fixing clip 903 at the bottom end of the tray 9. Two fixing clips 903 form a group, and multiple groups of fixing clips 903 are evenly distributed on the bottom surface of the tray 9. The position of the fixing clips 903 corresponds to the position of the second support rod 11. The multiple groups of fixing clips 903 are evenly distributed and can fully cooperate with the second support rod 11 to securely engage the tray 9 from multiple positions. This makes the tray 9 more securely and reliably fixed to the frame 1. During transport, regardless of the bumpy road conditions, it effectively prevents the tray 9 from shaking, shifting, or even falling off, ensuring the patient's safety on the stretcher in all aspects and providing a solid and stable support platform for patient transport. The tray 9 is interlocked with the second support rod 11 via the fixing clip 903, thus securing the tray 9 to the frame 1. The bottom of the tray 9 has a support block 904, and the fixing clip 903 and the support block 904 are distributed crosswise. When the tray 9 is not assembled with the frame 1, it is supported on the ground by the support block 904. When the tray 9 is used alone, the support block 904 provides stable support. The crosswise structural design, based on mechanical principles, makes the force on the tray 9 more even and stable when placed on the ground, preventing the tray 9 from tilting or tipping over due to unstable placement, thus ensuring the patient's safety on the tray 9. Furthermore, this independent support design provides great convenience when the pallet 9 needs to be operated separately, such as for cleaning, maintenance, or temporary placement of items.

[0040] Working principle:

[0041] Unfold the support 7, which is folded and stored at the bottom of the bracket 1. The principle is to operate the folding joint 5 on the second link 8, overcoming the resistance at the folding joint 5, so that the support 7 changes from a folded state to an unfolded state. At this time, the support 7 and the bracket 1 form a stable support structure, preparing for the subsequent placement of the tray 9 and carrying the patient. Check whether the sliding wheels 3 and auxiliary wheels 2 can rotate normally, and whether components such as the limiting headrest 902, straps 901, fixing clips 903, and support blocks 904 are intact. Ensure that all parts of the stretcher function normally to avoid malfunctions during use that may affect patient transport.

[0042] Place the tray 9 on the support frame 1, and engage the fixing clip 903 at the bottom of the tray 9 with the second support rod 11. This utilizes the special structural design of the fixing clip 903 and the second support rod 11 to achieve a stable connection between the tray 9 and the support frame 1 through the interlocking method, ensuring that the tray 9 will not move freely on the support frame 1 and providing a stable platform for carrying the patient. Place the patient steadily on the tray 9, with the head positioned at the limiting headrest 902. The shape and position of the limiting headrest 902 are used to fix and limit the patient's head, preventing the patient's head from moving freely during transport and causing secondary injury. Then, use the straps 901 on the side panel to secure the patient's body to the stretcher. The binding principle of the straps 901 is to use friction and restraint force to tightly connect the patient's body to the stretcher, preventing the patient from slipping off the stretcher.

[0043] When transferring the patient on a level surface, push the stretcher; the rolling principle of the sliding wheels 3 allows the stretcher to move quickly and smoothly. Simultaneously, the auxiliary wheels 2 on the first link 6 also contact the ground, providing support and balance. Based on the lever principle and the principle of force decomposition, the auxiliary wheels 2 share part of the weight of the stretcher and the patient, making the stretcher more stable during movement and reducing swaying caused by uneven ground or uneven pushing force. If it is necessary to fold the stretcher for passage through narrow spaces or for special storage, operate the folding joint 5 on the second link 8 to fold the support 7 into the bottom of the bracket 1. At this time, the auxiliary wheels 2 on the first link 6 contact the ground, facilitating movement of the stretcher in the folded state. The rolling of the auxiliary wheels 2 enables convenient movement of the stretcher in the folded state.

[0044] Upon arrival at the destination, untie strap 901 and carefully transfer the patient off the stretcher. Remove the support plate 9 from the support frame 1. If the stretcher needs to be stored, operate the folding joint 5 again to fold the support frame 7, and then properly store the stretcher in preparation for the next use.

[0045] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.
