Description

Technical Field

[0001] The present invention belongs to the technical field of rescue equipment, and particularly relates to a portable rescue stretcher. Background Art

[0002] As a tool for transferring injured persons, stretchers are widely used, mainly for the movement of injured persons with limited mobility. For example, during mountain climbing or outdoor adventure activities, since most scenarios are in the wild, the roads are winding and densely covered with thorns, it is easy to fall and get injured, resulting in the inability to walk. At this time, generally, one can only wait for rescue in place, and the rescue personnel need to carry a stretcher to search and rescue. After preliminary treatment, the injured person is carried back to the ambulance using the stretcher. Since the injured person may be far away from the location that the ambulance can reach, the common stretchers in the prior art are relatively large in size, which is not conducive to the rapid movement of the rescue personnel and limits the rescue speed. Although some simple stretchers use the method of setting a stretcher cloth between two stretcher poles and the stretcher cloth can be wound around the stretcher poles, such stretchers have a too simple structure. During the rescue process, the injured person is likely to slip off the stretcher cloth, and directly placing the stretcher carrying the injured person on the ground densely covered with thorns will cause discomfort to the injured person and even secondary injuries. Therefore, it is necessary to improve the existing stretcher. Summary of the Invention

[0003] In view of this, the present invention aims to overcome the defects in the prior art and proposes a portable rescue stretcher.

[0004] To achieve the above object, the technical solution of the present invention is realized as follows:

[0005] A portable rescue stretcher includes two stretcher poles arranged in parallel. The front ends of the two stretcher poles are fixed by a front end head, and the rear ends are fixed by a rear end head. A bearing cloth is provided between the two stretcher poles, and a plurality of sleeve rings are respectively provided on both sides of the bearing cloth, and the sleeve rings are sleeved on the corresponding stretcher poles. The front end head is in a square shape with a hole in the middle, including a front top plate, a front bottom plate, and a front end head arc portion between the two. The rear end head is in a square shape with a hole in the middle, including a rear top plate, a rear bottom plate, and a rear end head arc portion between the two. A front hanging hole is provided on the front top plate, and a rear hanging hole is provided on the rear top plate. The front and rear sides of the bearing cloth are respectively fixed to the front bottom plate and the rear bottom plate, and a functional cloth is provided between the front top plate and the rear top plate. The stretcher pole includes a base pole and an extension pole. The end of the extension pole facing the base pole is inserted into the base pole, and the part of the extension pole inserted into the base pole is slidably配合 with the base pole. The end of the extension pole different from the base pole extends out of the front end head, and the end of the base pole different from the extension pole extends out of the rear end head. The extension pole is pressed and fixed to the front end head arc portion, and the base pole is pressed and fixed to the rear end head arc portion. Bottom feet are provided at the bottoms of both the front bottom plate and the rear bottom plate.

[0006] Further, anti-slip patterns are provided on the parts of the extension pole extending out of the front end head and the parts of the base pole extending out of the rear end head. It should be noted that in the translation, "配合" is translated as "配合" because there is no exact English equivalent in this context, and it is more appropriate to keep it in Chinese for the sake of accuracy in the technical field. If there is a more accurate English expression in the actual context, it can be adjusted accordingly. Also, the description of the shape of the front and rear end heads as "回字形" is a literal translation for the purpose of accurately presenting the original text. If there is a more common or accurate English term for this shape in the relevant technical field, it can be further optimized.

[0007] Furthermore, one end of the functional cloth is detachably connected to the front top plate, and the other end is detachably connected to the rear top plate.

[0008] Furthermore, the expansion rod, base rod, front end head and rear end head are all made of carbon fiber material.

[0009] Furthermore, the functional cloth is made of cotton.

[0010] Furthermore, the rear top plate, the rear bottom plate and the rear end arc portion therebetween are an integrally formed structure.

[0011] Furthermore, the front top plate, the front bottom plate and the front end arc portion therebetween are an integrally formed structure.

[0012] Furthermore, the base includes a fixed support portion, and the fixed support portion includes a support column.

[0013] Compared with the prior art, the present invention has the following advantages:

[0014] The invention has a simple structure and reasonable design. When the stretcher poles are retracted, the entire stretcher is in a stowed state, taking up little space and facilitating portability. When needed, the stretcher poles can be extended to form a complete stretcher, making rescue operations more convenient and smooth. The stretcher is equipped with relatively independent functional and load-bearing fabrics, and the bottom foot is designed with a foldable support portion, which ensures the stretcher's load capacity while improving user comfort.

In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0025] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to internal connections between two components. Those skilled in the art can understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0026] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0027] A portable rescue stretcher, such as Figures 1 to 7As shown, the apparatus comprises two parallel stretcher poles 1, the front ends of which are secured by a front header 2 and the rear ends by a rear header 3. A stretcher cloth is provided between the two stretchers. Specifically, the stretcher cloth comprises a carrier cloth 4 between the two stretcher poles, with a plurality of loops 5 provided on either side of the carrier cloth, which fit over the stretcher poles on the corresponding side. The front end is in the shape of a U-shaped U-shape, comprising a front top plate 6, a front bottom plate 7, and a front end curved portion 8 therebetween. The rear end is in the shape of a U-shaped U-shape, comprising a rear top plate 9, a rear bottom plate 10, and a rear end curved portion 11 therebetween. The front and rear ends of the carrier cloth are secured to the front and rear bottom plates, respectively, and a functional cloth 12 is provided between the front and rear top plates.

[0028] The stretcher bar includes a base bar 13 and an expansion bar 14. The expansion bar is inserted into the base bar toward one end of the base bar, and the portion of the expansion bar inserted into the base bar slides with the base bar. That is, the stretcher bar is a telescopic rod structure. The existing technical solutions can be used to design the telescopic stretcher bar of the present invention. The base bar is a hollow structure, including the portion of the base bar extending outward from the rear end head. This ensures that the expansion bar can be better stored in the base bar, so that the stretcher bar has a shorter length when stored, and thus the rescue stretcher has a smaller volume. The expansion bar has a front end head extending outward from one end of the base bar, and a rear end head extending outward from one end of the base bar. The expansion bar is squeezed by the front end head arc portion and fixed to the front end head arc portion, and the base bar is squeezed by the rear end head arc portion and fixed to the rear end head arc portion. That is, the front end head arc portion is squeezed and deformed to clamp the expansion bar, and the rear end head arc portion is squeezed and deformed to clamp the base bar. The bottom of the front base plate and the bottom of the rear base plate are both provided with feet.

[0029] To ensure the stability of the stretcher poles when in use and when stored, positioning pins can be designed for positioning in the corresponding storage state when the stretcher poles are retracted and in the working state when they are extended. Of course, those skilled in the art can also use other methods for positioning or fixing, as long as the basic poles and the extension poles can be kept stable in the storage state and the working state respectively. For example, a front hanging hole 15 is provided on the front top plate, and a rear hanging hole 16 is provided on the rear top plate. In the storage state, the rescue stretcher structure is kept stable by a connecting rope 19 passing through the front and rear hanging holes, limiting the relative movement of the front and rear ends, thereby preventing the extension poles of the stretcher poles from extending. When the stretcher needs to be used, the connecting rope can be simply released.

[0030] During use, it is only necessary to release the lock on the stretcher rod or the front and rear end heads, and then stretch the stretcher rod. The load-bearing cloth and the functional cloth will unfold as the stretcher rod is stretched, forming a stretcher cloth structure with the load-bearing cloth at the bottom and the functional cloth at the top. The wounded is placed on the functional cloth, and the load-bearing cloth is used to provide effective support. The functional cloth is soft and comfortable. Preferably, one end of the functional cloth is detachably connected to the front top plate, and the other end is detachably connected to the rear top plate, so that the functional cloth can be installed, removed or replaced as needed. The part of the front end head extending out of the expansion rod and the part of the rear end head extending out of the base rod are both provided with anti-slip lines. The part of the front end head extending out of the expansion rod and the part of the rear end head extending out of the base rod can be used as handles for rescuers to hold.

[0031] For example, the expansion rod, base rod, front end, and rear end are all made of carbon fiber. The functional fabric is cotton. The rear top plate, rear bottom plate, and the curved portion of the rear end between them are an integrally molded structure. The front top plate, front bottom plate, and the curved portion of the front end between them are also an integrally molded structure. This rescue stretcher is lightweight and compact when stored, allowing a single rescuer to easily carry it, making it very convenient for quickly reaching the scene for rescue.

[0032] The base includes a fixed support portion, which includes a support column 17. In an optional embodiment, the base also includes a foldable support portion, which includes a support plate 18 hinged to the lower surface of the front / rear base plate, and a mounting groove is provided on the lower surface of the front / rear base plate. Under normal circumstances, the support plate is in a retracted state, and it fits with the bottom surface of the mounting groove of the front / rear base plate and does not protrude from the lower surface of the front / rear base plate. When needed, before lowering the stretcher, it is only necessary to manually flip the support plate downward so that the support plate rotates along the hinge axis to the working position. After opening the support plate and lowering the stretcher, the support plate can be used to form a support, preventing the carrier cloth from contacting uneven ground, especially preventing it from touching sharp objects on the ground, thereby ensuring the comfort of the person on the stretcher cloth.

[0033] The invention has a simple structure and reasonable design. When the stretcher poles are retracted, the entire stretcher is in a stowed state, taking up little space and facilitating portability. When needed, the stretcher poles can be extended to form a complete stretcher, making rescue operations more convenient and smooth. The stretcher is equipped with relatively independent functional and load-bearing fabrics, and the bottom foot is designed with a foldable support portion, which ensures the stretcher's load capacity while improving user comfort.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
