[0041] The present application proposes a portable emergency stretcher, which is specifically as follows:

[0042] For reference Figure 1 The present application mainly comprises a front pull component 1, a V-shaped bracket 2 connected to the front pull component 1 through a rotating shaft, a rear pull component 3 connected to one end of the V-shaped bracket 2 through a rotating shaft, an adjustment component 4 arranged at one end of the rear pull component 3 away from the V-shaped bracket 2, and a bracket 5 for supporting an infusion bottle of the injured person arranged on the adjustment component 4. Through the coordinated arrangement of the components, the folding effect can be achieved, so that the stretcher can be folded for easy taking during field operations.

[0043] For reference Figure 1 The front pulling assembly 1 includes two pulling rods 11. The front side of the pulling rods 11 is provided with a pulling handle 12 for supporting and pulling the front side of the stretcher.

[0044] For reference Figure 1 and Figure 2 The rear pull assembly 3 includes two rear leg rods 31, a third pad 32 and two rollers 33. One end of the rear leg rod 31 is connected to the support rod 211 through a rotating shaft. The third pad 32 is arranged at the middle of the connection between the two rear leg rods 31. The ends of the two rear leg rods 31 away from the support rod 211 are each provided with a rear pull handle 34. The two rollers 33 are arranged at the ends of the two rear pull handles 34 away from the support rod 211. The rear pull assembly 3 is used for rear support, and the rollers 33 contact the ground to achieve a push-pull effect. It can be used to help one person pull the stretcher, which helps to reduce the consumption of transportation manpower during field operations.

[0045] For reference Figure 1 and Figure 3 The V-shaped bracket 2 is arranged at the middle of the connection between the front pull component 1 and the rear pull component 3. By changing the distance between the front pull component 1 and the rear pull component 3, the opening curvature of the V-shaped bracket 2 can be changed. Since both ends of the V-shaped bracket 2 are connected to the front pull component 1 and the rear pull component 3 through a rotating shaft, if the opening curvature of the V-shaped bracket 2 is adjusted, it needs to be fixed, so an adjustment component 4 is set; and the adjustment component 4 includes two adjustment blocks 41, two fixed shafts 42 and a folding rod 43; the two adjustment blocks 41 are fixedly connected to the rear leg rod 31 and the pull rod 11 respectively; the two fixed shafts 42 are respectively arranged on the two adjustment blocks 41 and fixedly connected to the folding rod 43; the two ends of the folding rod 43 are respectively inserted into the two adjustment blocks 41 and fixed by the two fixed shafts 42. During use, first insert the two ends of the folding rod 43 into the two adjusting blocks 41. At this time, the fixed shaft 42 is connected to the adjusting block 41 along with the folding rod 43, and a screw is provided on the fixed shaft 42. The fixed shaft 42 is fastened to the adjusting block 41 by the screw, so that the opening arc of the opening bracket of the V-shaped bracket 2 is stabilized. After stabilization, the bracket 5 can be clamped on the folding rod 43 and fixed by bolts.

[0046] For reference Figure 1, and the V-shaped support 2 mainly includes a front part 21, a rear part 22 and an elastic strip 23; the two sides of the front part 21 are connected to the inner side of the two pull rods 11 at the same time, and the rear part 22 is connected to the side of the front part 21 away from the pull rod 11. There are multiple elastic strips 23, which are arranged in the middle of the connection between the front part 21 and the rear part 22. When the patient leans on the V-shaped support, the back and thighs are supported by the front part 21 and the rear part 22, and in order to increase the comfort of the injured, multiple elastic strips 23 are arranged at the connection between the front part 21 and the rear part 22. The elastic strips 23 can securely hold the patient's buttocks, increasing the comfort of the patient during transfer.

[0047] For reference Figure 1 In order to increase the comfort of the patient when lying flat, the front side member 21 is further optimized, and the front side member 21 includes two support rods 211, a first pad 212 and a pillow board 213; the pull rod 11 is connected to the center of the middle part and the upper edge of the support rod 211; the first pad 212 is fixedly connected to the middle part of the connection between the two support rods 211; the pillow board 213 is fixedly connected to the upper side of the middle part of the connection between the two support rods 211. The support rod 211 is used to support the first pad 212, so that the surface of the first pad 212 is flattened to form the back of the injured person. The connection formed by the support rod 211 and the pull rod 11 can fold the pull rod 11 and the support rod 211 in the folded state, which increases the storage and facilitates the subsequent taking; and the pillow board 213 is arranged on the upper side of the support rod 211 and corresponds to the head position of the patient when lying down. The pillow board 213 adopts a soft sponge to increase the softness, which can reduce the bump caused by the shaking of the head when transferring the injured person.

[0048] For reference Figure 1 The rear part 22 is used to support the thigh of the patient, and its structure is similar to that of the front part 21. The rear part 22 includes two connecting rods 221 and a second pad 222. The second pad 222 is arranged at the middle of the connection between the two connecting rods 221. The two connecting rods 221 are used to support the second pad 222 as a plane, which is used to support the injured. At the same time, the connecting rod 221 is connected to the support rod 211 and the rear leg rod 31, and one side of the connecting rod 221 is connected to the inner side of the support rod 211, and the other side of the connecting rod 221 is connected to the outer side of the rear leg rod 31. Therefore, when folding, the closure is completed in sequence. During the closure period, the folding rod 43 can be removed through the fixed shaft 42. After the folding rod 43 is removed and folded, the overall folded structure is tied together, so that it can be carried on the back of the first aid personnel during the field, which is convenient for technical operation.

[0049] In the utility model, the working steps of the device are as follows:

[0050] 1. First, fold and bundle the device, which is small in size and easy to carry between team members during field operations;

[0051] 2. Secondly, when an injured patient appears, the structure used to tie up the device can be removed and the folding rod 43 can be inserted into the adjustment block 41;

[0052] 3. Then, the distance between the front pull component 1 and the rear pull component 3 is adjusted according to the height, weight and size of the patient, and the fixing shaft 42 is used to fix the patient;

[0053] 4. Finally, the patient is transferred to the device. If infusion is needed in time, the support 5 is set, and then the patient can be transferred by pulling the rear pull component 3 through the front pull component 1. Two people can also lift the rescue stretcher to transfer the patient.

[0054] The above shows and describes the basic principles, main features and advantages of the utility model.
