Technical Field

[0001] This utility model relates to the field of stretcher technology, specifically to a stretcher that can be quickly deployed for emergency medicine. Background Technology

[0002] In the process of receiving patients, the emergency department of a hospital usually needs to ensure that in the event of sudden illness or accidental injury, professional and scientific treatment can be obtained in the shortest possible time. The stretcher is a commonly used item in the emergency treatment process. When the injured person loses consciousness or has impaired bodily functions and is unable to move on their own, the emergency personnel can use the stretcher to quickly and safely transfer the injured person to the emergency point for medical treatment and save the injured person's life.

[0003] Existing deployable stretchers are usually fixed in shape, taking up a lot of space, or have a complex foldable structure, which affects operational efficiency. They also cannot effectively reduce space occupation when storing stretchers, resulting in many inconveniences.

[0004] This invention addresses these issues by proposing a rapidly deployable stretcher for emergency medicine, aiming to solve the aforementioned problems. The stretcher can be quickly deployed during use and occupies little space when stored, making it easy to carry and use. Utility Model Content

[0005] In view of the above-mentioned shortcomings in the prior art, this utility model provides a stretcher that can be quickly deployed for emergency medicine.

[0006] To achieve the aforementioned objectives, the technical solution adopted by this utility model is as follows:

[0028] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings, so that the advantages and features of this utility model can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0029] The terms "comprising" and "having," and any variations thereof, used in the specification, claims, and accompanying drawings of this utility model are intended to cover non-exclusive inclusion. The terms "first," "second," etc., used in the specification, claims, and accompanying drawings of this utility model are used to distinguish different objects, not to describe a specific order.

[0030] Combined with appendix Figure 1-3An emergency medicine stretcher that can be quickly deployed includes a frame and a stretcher cloth 1. The frame includes a first fixed rod 2, a second fixed rod 3, a first movable rod 4, a second movable rod 5, and an end rod 6. There are two first fixed rods 2 and two second fixed rods 3, and the two first fixed rods 2 and two second fixed rods 3 are arranged in parallel and opposite to each other. The frame is enclosed to form a rectangle, and the stretcher cloth 1 is connected to the end rod 6, the first movable rod 4, the second movable rod 5, the first fixed rod 2, and the second fixed rod 3.

[0031] Any set of first fixing rods 2 and second fixing rods 3 can be detachably connected via a connecting component. The first fixing rod 2 is connected to the second fixing rod 3 via a connecting plate 7. Both ends of the connecting plate 7 are hinged to the first fixing rod 2 and the second fixing rod 3, respectively. The length of the connecting plate 7 ensures that the first fixing rod 2 and the second fixing rod 3 are not in direct contact, and a section is exposed in the middle. A connecting component is provided on the end of the second fixing rod 3 facing the first fixing rod 2. The connecting component is used for assembling and disassembling the first fixing rod 2 and the second fixing rod 3.

[0032] The connecting components include a connecting rod 14, a limiting plate 15, and a second spring 16. The limiting plate 15 is located inside the second fixed rod 3. The connecting rod 14 is slidably connected to one end of the second fixed rod 3 facing the first fixed rod 2. A second spring 16 is located between the limiting plate 15 and the connecting rod 14. One end of the second spring 16 is fixedly connected to the limiting plate 15, and the other end is fixedly connected to the connecting rod 14. Therefore, the connecting rod 14 is slidably disposed inside the first fixed rod 2, but is not directly connected to it. An L-shaped groove 17 is provided on the side of the second fixed rod 3. A lever 18 is located within the L-shaped groove 17 and is fixedly connected to the connecting rod 14. It can move within the L-shaped slide 17, which includes a vertical groove along the length of the second fixed rod 3 and a horizontal groove that communicates with the vertical groove. The horizontal groove is located on the side away from the first fixed rod 2. When the lever 18 is engaged in the vertical groove, the connecting rod 14 will penetrate into the first fixed rod 2, so that the first fixed rod 2 and the second fixed rod 3 form the shape of the stretcher in use. When the lever 18 is engaged in the horizontal groove, the connecting rod 14 will disengage from the first fixed rod 2 and slide out, so that the two sections of the stretcher form a foldable state, that is, the first fixed rod 2 and the second fixed rod 3 are separated. The stretcher cloth 1 is soft, so it can be folded quickly. Since the connecting rod 14 normally moves outward under the action of the spring 16, the lever 18 is in the vertical groove of the L-shaped slide 17 in this state, and the entire stretcher is in a usable state. When it is necessary to fold the entire stretcher, the connecting rod 14 is operated by hand to make the lever 18 move into the horizontal groove of the connecting rod 14, the position of the connecting rod 14 will be limited, and it will also disengage from the first fixing rod 2, which facilitates quick folding.

[0033] In use, the first fixing rod 2 and the second fixing rod 3 are flipped relative to each other so that one end of the first fixing rod 2 and the second fixing rod 3 are facing each other. The position of the lever 18 in the L-shaped slide groove 17 is adjusted so that the lever 18 is located in the vertical groove of the L-shaped slide groove 17. The L-shaped slide groove 17 no longer restricts the position of the lever 18, and therefore no longer restricts the position of the connecting rod 14. Under the action of the second spring 16, the connecting rod 14 moves out of the second fixing rod 3 and slides into the first fixing rod 2, thereby realizing the connection between the first fixing rod 2 and the second fixing rod 3 to facilitate the normal use of the stretcher.

[0034] Combined with appendix Figure 1 , 3 4. A first movable rod 4 and a second movable rod 5 are slidably connected inside the first fixed rod 2 and the second fixed rod 3, respectively. The first movable rod 4 and the second movable rod 5 protrude from the ends of the first fixed rod 2 and the second fixed rod 3 that are separated from each other. A limiting component is provided at the connection between the first fixed rod 2, the second fixed rod 3 and the first movable rod 4, the second movable rod 5. The limiting component limits the extreme positions of the first movable rod 4 and the second movable rod 5 protruding from the first fixed rod 2 and the second fixed rod 3.

[0035] See Figure 4 The limiting component includes an exposed hole 8, a limiting rod 9, a through hole 10, and a cavity 11. The side of the first fixed rod 2 and the second fixed rod 3 at opposite ends is provided with an exposed hole 8. The side of the first movable rod 4 and the second movable rod 5 at opposite ends is provided with a through hole 10 and a cavity 11. The through hole 10 and the cavity 11 are connected. The limiting rod 9 is slidably connected in the through hole 10. An end plate 12 is slidably connected in the cavity 11. The end plate 12 is connected to one end of the limiting rod 9. A spring 13 is provided between the end plate 12 and the cavity 11.

[0036] Pulling the first movable rod 4 and the second movable rod 5 outwards, after the position of the limiting rod 9 corresponds to the position of the exposed hole 8, the limiting rod 9 moves outwards from the through hole 10 under the action of the end plate 12 and the spring 13. One end of the limiting rod 9 is exposed from the exposed hole 8, thereby limiting the relative position between the first movable rod 4 and the first fixed rod 2, as well as the relative position between the second movable rod 5 and the second fixed rod 3, so as to realize the rapid deployment of the stretcher.

[0037] Combined with appendix Figure 3 and Figure 4 The diameter of the cavity 11 is larger than the diameter of the through hole 10, and it is stepped, so that the diameter of the end plate 12 is larger than the diameter of the limiting rod 9 and also larger than the diameter of the through hole 10. Therefore, the end plate 12 will not come out of the through hole 10. When the limiting rod 9 moves, the end plate 12 will move inside the cavity 11, but will not move out of the cavity 11, thereby limiting the extreme position of the limiting rod 9.

[0038] See Figure 1The stretcher cloth 1 has a notch 19, which corresponds to the connection between the first fixed rod 2 and the second fixed rod 3, the connection between the first fixed rod 2 and the first movable rod 4, and the connection between the second fixed rod 3 and the second movable rod 5.

[0039] The notch 19 in the stretcher fabric 1 does not affect the relative folding between the first fixing rod 2 and the second fixing rod 3, nor does it affect the position adjustment of the first movable rod 4 and the second movable rod 5. When operating, medical staff can easily grip the stretcher by inserting their fingers into the notch 19.

[0040] The above description is only used to illustrate the technical solution of this utility model, and is not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. Any equivalent structural or procedural transformations made using the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
