Description

Technical Field

[0001] The utility model relates to a rescue stretcher for narrow spaces, belonging to the field of medical first aid auxiliary equipment. Background Art

[0002] In the process of medical first aid services, rescue stretchers are often needed to urgently transport patients or the injured. Existing rescue stretchers generally have a fixed length of about 1.9 meters. In some special places such as roadways, ships, and corridor entrances, due to the relatively narrow space, it is difficult for the rescue stretcher to turn. On the one hand, rescue personnel need to perform operations such as single-handed and high-lifting, which will greatly increase the labor intensity of the rescue personnel; on the other hand, it will also cause the transfer speed of the stretcher to be slower, thus delaying precious rescue time. Content of the Utility Model

[0003] According to the above deficiencies in the prior art, the technical problem to be solved by the utility model is to provide a rescue stretcher for narrow spaces with adjustable length.

[0004] The rescue stretcher for narrow spaces of the utility model includes two outer rods arranged in parallel. The right ends of both outer rods are slidably connected with inner rods. A locking assembly is connected between the cooperating outer rod and inner rod. Handles are provided at the left ends of both outer rods and the right ends of both inner rods. A leg support plate is fixedly connected between the two outer rods. A leg restraint belt is connected to the leg support plate. The right ends of both outer rods are hinged with first swing arms. The right ends of both inner rods are hinged with second swing arms. The right end of the corresponding first swing arm is hinged with the left end of the second swing arm. A hip support plate is fixedly connected between the two first swing arms. A hip restraint belt is connected to the hip support plate. A back support plate is fixedly connected between the two second swing arms. A chest restraint belt is connected to the back support plate.

[0005] Further, wheel frames are provided at the bottoms of the outer rod and the inner rod, and rollers are rotatably installed in each wheel frame.

[0006] Further, the locking assembly includes a row of positioning holes provided at the top of the inner rod and a positioning pin threadedly connected to the top of the outer rod, and the positioning pin is adapted to the positioning holes.

[0007] Further, the handle is annular.

[0008] Further, an anti-slip sleeve is connected to the handle.

[0009] Further, a support rod is connected to the right end of the inner rod, and a hook is provided at the upper end of the support rod.

[0010] Further, the support rod and the inner rod are threadedly connected.

[0011] The beneficial effects of the utility model compared with the prior art are:

[0012] For the rescue stretcher used in a narrow space described in the present utility model, when in normal use, the leg support plate, the hip support plate and the back support plate are in the same plane, enabling the patient to lie flat; when used in a narrow space, the position of the inner rod inside the outer rod can be adjusted as needed, thereby shortening the overall length of the device. At this time, the leg support plate, the hip support plate and the back support plate are in a Z shape, enabling the patient to lie semi-recumbent, effectively reducing the turning difficulty, not only reducing the labor intensity of the rescue personnel, but also ensuring the transfer speed of the patient, thus winning precious rescue time for the patient.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] The following further describes the embodiments of the present utility model with reference to the drawings:

[0017] Embodiment 1:

[0018] As Figure 1 , Figure 2 shown, the rescue stretcher used in a narrow space described in the present utility model includes two parallel outer rods 3. The right ends of both outer rods 3 are slidably connected with inner rods 11. A locking assembly 7 is connected between the cooperating outer rod 3 and inner rod 11. Handles 1 are provided at the left ends of both outer rods 3 and the right ends of both inner rods 11. A leg support plate 14 is fixedly connected between the two outer rods 3. A leg restraint strap 17 is connected to the leg support plate 14. The right ends of both outer rods 3 are hinged with first swing arms 6. The right ends of both inner rods 11 are hinged with second swing arms 8. The right end of the corresponding first swing arm 6 is hinged to the left end of the second swing arm 8. A hip support plate 15 is fixedly connected between the two first swing arms 6. A hip restraint strap 18 is connected to the hip support plate 15. A back support plate 16 is fixedly connected between the two second swing arms 8. A chest restraint strap 19 is connected to the back support plate 16.

[0019] During normal use, the leg support plate 14, the hip support plate 15 and the back support plate 16 are in the same plane, allowing the patient to lie flat; when used in a narrow space, the position of the inner rod inside the outer rod can be adjusted as needed, thus shortening the overall length of the device. At this time, the leg support plate 14, the hip support plate 15 and the back support plate 16 are in a Z shape, allowing the patient to lie semi-reclined. The leg restraint strap 17, the hip restraint strap 18 and the chest restraint strap 19 can restrain the patient on the stretcher to prevent the patient from falling off the stretcher. The rescuer can lift the handle 1 to transfer the patient.

[0020] The rescue stretcher for narrow spaces of the present utility model can reduce the turning difficulty in narrow spaces, not only reducing the labor intensity of the rescuers, but also ensuring the transfer speed of the patient, thus winning precious rescue time for the patient.

[0021] Embodiment 2:

[0022] As Figure 1 、 Figure 2 shown, on the basis of Embodiment 1,

[0023] Furthermore, wheel frames 4 are provided at the bottoms of both the outer rod 3 and the inner rod 11. A roller 5 is rotatably installed in each wheel frame 4. During rescue in a narrow space such as a pipeline site, under the action of the rollers 5, the rescue stretcher for narrow spaces of the present utility model can be pulled, which is beneficial to the transfer of the patient;

[0024] Furthermore, the locking assembly 7 includes a row of positioning holes 13 provided at the top of the inner rod 11 and a positioning pin 12 threadedly connected to the top of the outer rod 3. The positioning pin 12 is adapted to the positioning holes 13. By inserting the positioning pin 12 into different positioning holes 13, the position of the inner rod 11 inside the outer rod 3 can be adjusted, with a simple structure and convenient adjustment;

[0025] Furthermore, the handle 1 is annular. During rescue in a narrow space such as a wellhead site, a lifting rope can be connected to the handle 1, so that the rescue stretcher for narrow spaces of the present utility model can be lifted, which is beneficial to the transfer of the patient;

[0026] Furthermore, an anti-slip sleeve 2 is connected to the handle 1, which can increase the friction between the handle 1 and the hand of the rescuer, making the grip on the handle 1 more firm;

[0027] Furthermore, a support rod 9 is connected to the right end of the inner rod 11. A hook 10 is provided at the upper end of the support rod 9. The hook 10 can hook the infusion bag, facilitating infusion for the patient during the transfer of the patient;

[0028] Furthermore, the support rod 9 and the inner rod 11 are threadedly connected. When the patient does not need to be infused, the support rod 9 can be removed, thus not affecting the carrying and lifting of the patient.

[0029] It should be specifically noted that: in the description of the present utility model, the orientation or positional relationship indicated by terms such as "left" and "right" is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model rather than requiring the present utility model to be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model.
