Description

Technical Field

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

[0002] As one of the most distinctive innovations in 20th-century aviation technology, the helicopter has greatly expanded the application range of aircraft. A typical dual-use product, helicopters can be widely used in transportation, patrol, tourism, rescue, and many other fields. Helicopter rescue is not only adaptable to various terrain conditions but also offers relatively fast rescue speeds.

[0003] For example, Chinese utility model patent (CN214632630U) discloses a helicopter emergency rescue strap stretcher, which describes: "By protruding blocks at the four corners of the surface where the fixing and snap-fit ​​parts are located in the stretcher board, a steel ring passes through the middle of the protrusion, a buckle is fastened inside the steel ring, a connecting block is fixedly connected to the top of the buckle, a steel cable is fixedly connected to the top of the connecting block, and a limit block and a collapsing cylindrical tube pass through the end of the steel cable away from the stretcher board in sequence, so that the helicopter can receive and drop the patient in the air without landing, thus gaining more rescue time for the patient." It also describes the technical problem that "the landing of helicopters is limited by the terrain. If there is no suitable terrain for landing near the patient's location, the patient needs to be transferred to the ground, which delays the patient's rescue time."

[0004] In summary, the existing technology has the following technical problems: the overall structure is fixed and cannot be folded, it takes up a lot of space when not in use, and its function is limited. Regardless of whether the person is seriously injured or slightly injured, they can only be transported lying flat, which limits the number of rescuers when transporting slightly injured persons. Therefore, this application proposes a new type of rescue stretcher to provide a new technical solution to solve the above-mentioned technical problems. Utility Model Content

[0005] Based on this, it is necessary to provide a new type of rescue stretcher to address the aforementioned technical problems. Through the structural design of the stretcher body and the mesh frame body, the device can be used to transport patients with minor and serious injuries in different ways. When transporting seriously injured patients, the unfolding of the stretcher body allows for relatively stable transport. When transporting patients with minor injuries, the mesh frame body can be unfolded by folding the stretcher body, and multiple patients with minor injuries can be transported through the mesh frame attached to the mesh frame body, thereby improving transport efficiency.

[0026] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention 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 invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0027] Please refer to Figures 1-5 A new type of rescue stretcher, comprising:

[0028] The stretcher body 1 includes two symmetrically arranged frame components 3, with a connecting component 4 between the two frame components 3. Both frame components 3 are rotatably connected to the connecting component 4, and a stop component 5 is provided on the side of the two frame components 3 that is close to one end. In order to improve the sturdiness of the frame components 3, a reinforcing rod 6 is fixedly connected laterally to the inner side of the frame components 3.

[0029] In other embodiments, the stop component 5 includes two support rods. The ends of the two support rods that are far apart from each other are fixedly connected to the frame component 3 at the same end. The ends of the two support rods that are close to each other are rotatably connected. An anti-rotation plate is provided at the upper end of one of the support rods, so that the two support rods can be stopped from rotating after being unfolded to a certain extent, thereby achieving the effect of limiting the unfolding of the two frame components 3.

[0030] Furthermore, the frame component 3 is fixedly connected to both sides with a first hanging ear 7, the end of the connecting component 4 is fixedly connected to a second hanging ear 8, and the middle of the connecting component 4 is fixedly connected to a third hanging ear 9.

[0031] The main body 2 of the mesh frame is located at both ends of the main body 1 of the stretcher. The main body 2 includes a connecting frame 11, with fixed rods 12 fixedly connected to both ends of the connecting frame 11. A movable rod 14 is rotatably connected to the middle of the connecting frame 11. Both the fixed rods 12 and 14 are equipped with hanging rings for attaching the mesh surface. The fixed rods 12 and 14 are set at a 90-degree angle. Connecting seats 10 are fixedly connected to the ends of the two frame components 3 that are furthest from each other. The connecting frame 11 is detachably connected to the frame components 3 through the connecting seats 10. A first extension rod 13 is provided at the end of the fixed rod 12 furthest from the connecting frame 11, and the first extension rod 13 can extend outward along the axis of the fixed rod 12. A second extension rod 15 is provided at the end of the movable rod 14 furthest from the connecting frame 11, and the second extension rod 15 can extend outward along the axis of the movable rod 14. Both the first extension rod 13 and the second extension rod 15 are equipped with hanging rings for attaching the mesh surface.

[0032] This application ensures the safety of the injured during the rescue process and provides reliable protection for the rescue work. This application sets out two states.

[0033] 1. Stretcher unfolded as follows Figure 1 As shown;

[0034] This is the fully deployed state. The main stretcher body 1 has a sturdy structure with nylon fabric installed in the middle, and is securely fixed with ropes. It is equipped with dedicated net frame bodies 2 on both sides, which ensure that seriously injured persons can be transferred smoothly and safely during rescue operations. This design provides a stable and comfortable rescue environment for seriously injured persons, effectively preventing secondary injuries during transfer.

[0035] In the rescue stretcher, the main body 1 plays a crucial dual role. First, it is key in rescue operations, especially when handling casualties with special needs, ensuring the safety and stability of the casualty during transport. Second, the main body 1 serves as the connecting link between the main body 2 and the overall rescue stretcher, and also acts as the framework for connecting to the helicopter's securing ropes.

[0036] In the mechanical structure of the rescue stretcher, the stopping component 5 plays a crucial role, its main function being to provide necessary support and stability. The original intention of designing the stopping component 5 is to ensure that the stretcher does not fold due to changes in the center of gravity when the injured person is using it, thereby preventing the injured person from suffering unnecessary secondary injuries.

[0037] To ensure effective connection between the rescue platform and the rescue helicopter, it is crucial to install dedicated grappling hooks for connecting rescue ropes. Multiple grappling hook installation points are designed on the rescue platform, namely, the first lug 7, the second lug 8, and the third lug 9.

[0038] II. Stretcher folding position as follows Figure 5 As shown;

[0039] In its folded state, the stretcher body 1 presents a compact structure. By adding a net surface to the bottom net frame body 2 and securing it firmly with ropes, a suitable seating surface for rescuers with minor injuries is formed. This design allows casually injured individuals to sit on the net surface, enabling rapid and convenient transfer and rescue.

[0040] The main body 2 of the rescue stretcher's net frame is primarily responsible for carrying uninjured or slightly injured trapped individuals. While ensuring passenger safety, each net frame body 2 can be equipped with two nets for seating, enabling the platform to quickly and safely transfer up to four people in an emergency. Furthermore, through the carefully designed first extension rod 13 and second extension rod 15, the rescue stretcher achieves partial folding and telescopic functions, thus achieving portability. The telescopic movement of the first extension rod 13 and second extension rod 15 is hydraulically controlled. Hanging rings are also provided on the outer sides of the first extension rod 13 and second extension rod 15, allowing ropes to be pulled out and fixed to these rings, thus securing and stabilizing the net frame and effectively enhancing its load-bearing capacity and stability. This prevents the risk of patients slipping due to stretcher swaying or tilting.

[0041] The multi-functional design described above enables this device to flexibly select rescue methods based on the severity of the injuries.

[0042] We hope this product can be applied in a wide range of scenarios, including natural disaster relief (during natural disasters such as earthquakes and floods, helicopter rescue stretchers can quickly reach disaster areas to safely transfer seriously injured people, while also efficiently rescuing lightly injured people, improving rescue efficiency) and medical emergency care (for emergency medical situations in remote areas or places with inconvenient transportation, this stretcher can be quickly transported to the scene by helicopter to promptly send the injured to the hospital for treatment). It provides an efficient and practical solution for aerial rescue operations.
