Abstract
Description
Technical Field
[0001] This application relates to a wounded rescue device, and more particularly to a wounded transport device. Background Technology
[0002] Transporting the wounded in a firefight presents significant challenges. Rescuers are exposed to enemy fire for extended periods, increasing the risk of injury or even death.
[0003] Current methods of transport generally involve either support or stretcher transport. Support transport usually does not require the use of equipment or tools, but it demands excellent physical strength from the rescuer. While stretcher transport provides relatively better protection for the injured, it typically requires two rescuers working together, necessitating a significant amount of manpower. Moreover, regardless of the method, the rescuer remains close to the injured, making it difficult to operate discreetly. Rescuers are exposed to fire for extended periods and are relatively high-profile targets. Summary of the Invention
[0004] In view of the above problems, this application aims to provide a wounded person transport device that enables rescuers to be exposed to fire for the shortest possible time and to use surrounding cover to conceal themselves during the transport process, thereby ensuring the safety of the rescuers as much as possible.
[0005] This application proposes a casualty transport device for assisting rescuers in transporting casualties in a fire-prone environment, comprising: a casualty carrying unit, a winch unit, and a winch.
[0006] The casualty support unit includes: a spinal support plate and a support arm;

[0018] When the casualty-bearing unit is in the deployed state, the support arms on the underside of the first, second, third, and fourth wing plates are perpendicular to the spinal support plate, forming an "I" shape.
[0019] When the casualty-bearing unit is in a folded state, the support arms on the underside of the first, second, third, and fourth wing plates rotate and approach the spinal support plate, forming a straight line.
[0020] A pair of spring pins are formed on the underside of the first wing plate, the second wing plate, the third wing plate, and the fourth wing plate, respectively. When the casualty carrier unit is in the deployed state, the pair of spring pins are located on both sides of the corresponding support arm, which restricts the corresponding support arm and ensures that the casualty carrier unit remains in the deployed state during its movement.
[0021] Preferably, the lower part of the rotating shaft has a plurality of lugs, which are located below the stop portion; the plurality of lugs are evenly distributed in the circumferential direction of the rotating shaft; each lug corresponds to a fixing strip; the first end of the fixing strip has a mounting hole, and the fixing strip is mounted to the corresponding lug through the mounting hole;
[0022] Each fixing strip has multiple fixing pin holes; by inserting fixing pins into the fixing pin holes, the fixing pins are inserted into the appropriate positions, thereby fixing the rotating shaft in the appropriate positions by means of the fixing strips.

[0030] Preferably, it further includes a corner support unit; the corner support unit is used to fix the cable at the position where it needs to be turned;
[0031] The corner support unit includes a C-shaped elastic plate; a curved cylinder; the curved cylinder is fixed to the upper side of the C-shaped elastic plate, and sharp teeth are formed at both ends of the lower side of the C-shaped elastic plate; handles are formed at both ends of the C-shaped elastic plate.
[0032] The cable passes through the curved cylinder, thus providing a smooth transition at the corner.

[0056] The following is a detailed description of the casualty transport device of this application, with reference to the accompanying drawings.
[0057] This application discloses a casualty transport device for assisting rescuers in transporting casualties in a fire-prone environment. It includes: a casualty carrying unit 10, a winch unit 20, a corner support unit 30, and a winch 40. Figure 1 As shown.
[0058] like Figure 1-8 As shown, the casualty support unit 10 includes: a spinal support plate 11 and a support arm.
[0059] The spinal support plate 11 forms a laterally extending first wing plate 12a on its upper first side and a laterally extending second wing plate 12b on its upper second side. The first wing plate 12a and the second wing plate 12b are used to support the scapular position of the injured person.
[0060] The spinal support plate 11 forms a laterally extending third wing plate 13a on its lower first side and a laterally extending fourth wing plate 13b on its lower second side. The third wing plate 13a and the fourth wing plate 13b are used to support the hip position of the injured person.
[0061] The first wing plate 12a, the second wing plate 12b, the third wing plate 13a, and the fourth wing plate 13b can be flush with the upper side of the spinal support plate 11.
[0062] The spinal support plate 11 forms a circular head support plate 17 at its upper end. A recess 17a is formed on the upper side of the head support plate 17 to stably support the back of the patient's head.
[0063] Support arms are respectively installed on the underside of the first wing plate 12a, the second wing plate 12b, the third wing plate 13a, and the fourth wing plate 13b; the support arms include a first support arm 14a, a second support arm 14b, a third support arm 15a, and a fourth support arm 15b. Specifically,
[0064] Each support arm has a wheel 16 rotatably mounted on its second end; the outer circumference of the wheel 16 is toothed to increase grip.
[0065] Support arm pivots 19 are formed on the lower sides of the first wing plate 12a, the second wing plate 12b, the third wing plate 13a, and the fourth wing plate 13b, respectively. The first support arm 14a, the second support arm 14b, the third support arm 15a, and the fourth support arm 15b are rotatably mounted on the support arm pivots 19 on the lower sides of the corresponding first wing plate 12a, the second wing plate 12b, the third wing plate 13a, and the fourth wing plate 13b through mounting holes at their first ends.
[0066] Taking the first support arm 14a as an example, a mounting hole 16a is formed at its first end. The first support arm 14a is mounted on the rotating shaft 19 on the lower side of the first wing plate 12a through the mounting hole 16a.
[0067] The rotatable connection between the pivot and the support arm allows the casualty carrier unit to be in both unfolded and folded states.
[0068] When the casualty carrier unit is in the deployed state, such as Figure 1 , 2 As shown, the support arms on the lower side of the first wing plate 12a, the second wing plate 12b, the third wing plate 13a, and the fourth wing plate 13b are perpendicular to the spinal support plate 11, and the casualty bearing unit is in the shape of an "I".
[0069] When the casualty carrier unit is in the folded state, the support arms on the underside of the first wing plate 12a, the second wing plate 12b, the third wing plate 13a, and the fourth wing plate 13b rotate and approach the spinal support plate, and the casualty carrier unit is in the shape of "I".
[0070] A pair of spring pins 18 are formed on the first wing plate 12a, the second wing plate 12b, the third wing plate 13a, and the fourth wing plate 13b respectively. When the casualty carrying unit 10 is in the deployed state, the pair of spring pins 18 are located on both sides of the corresponding support arm, which restricts the corresponding support arm so that the casualty carrying unit 10 remains in the deployed state during its movement.
[0071] The cable unit 20 includes: a pivot member 21, a cable frame member 22, and a cable rod 23; as shown in the figure. Figure 9-19 As shown.
[0072] The pivot component 21 includes a pivot 21a; the lower part of the pivot 21a has an outwardly extending stop 21b; the lower part of the pivot 21a is connected to a fixing strip 21d, which fixes the pivot 21a to a suitable position away from the wounded and suitable for concealing the rescuer, such as behind an artificial shelter or a natural shelter.
[0073] The lower part of the rotating shaft 21a has a plurality of lugs 21c, which are located below the stop portion 21b. The lugs 21c are evenly distributed in the circumferential direction of the rotating shaft 21a. Each lug 21c corresponds to a fixing strip 21d. The first end of the fixing strip 21d has a mounting hole 21d1, through which the fixing strip 21d is mounted to the corresponding lug 21c.
[0074] Each fixing strip 21d has multiple fixing nail holes 21d2. Fixing nails 21e are inserted into the fixing nail holes 21d2, and then inserted into appropriate locations, such as the ground or wall, thereby fixing the rotating shaft 21a via the fixing strip 21d. The fixing nail 21e can be like a regular nail, or it can have a triangular cross-section, resulting in stronger adhesion after the fixing nail is inserted into the ground. The shape of the fixing nail holes 21d2 corresponds to the cross-sectional shape of the fixing nail. There are at least three fixing strips, ensuring relative stability of the rotating shaft 21d after multi-point fixing. In the standby state, the fixing strips fold along their corresponding lugs, making the fixing strips parallel to the rotating shaft.
[0075] The cable frame component 22 includes a longitudinal sleeve 22a; the longitudinal sleeve 22a is rotatably fitted onto the upper end of the rotating shaft 21a and supported on the upper side of the stop portion 21b; a transverse sleeve 22b is integrally formed at the upper end of the longitudinal sleeve 22a; a cable support frame is formed on the side of the longitudinal sleeve 22a, and the cable support frame is used to wind the cable 40 thereon.
[0076] The cable support frame includes a first cable support rod 22c and a second cable support rod 22d; the first cable support rod 22c and the second cable support rod 22d are evenly distributed in the circumferential direction of the longitudinal sleeve 22a.
[0077] The first cable support rod 22c includes a first segment 22c1 and a second segment 22c2; the second cable support rod 22d includes a third segment 22d1 and a fourth segment 22d2.
[0078] The first sub-segment 22c1, the second sub-segment 22c2, the third sub-segment 22d1, and the fourth sub-segment 22d2 are parallel to the longitudinal sleeve 22a. The distances between the first sub-segment 22c1 and the third sub-segment 22d1 and the longitudinal sleeve are defined as a first distance; the distances between the second sub-segment 22c2 and the fourth sub-segment 22d2 and the longitudinal sleeve are defined as a second distance. The first distance is greater than the second distance, resulting in different cable winding radii for the cable support frame. Therefore, when labor-saving is required, the cable is wound on the second sub-segment 22c2 and the fourth sub-segment 22d2; when rapid cable winding is required, the cable is wound on the first sub-segment 22c1 and the third sub-segment 22d1.
[0079] The lever 23 can be detachably inserted into the transverse sleeve 22b; the lever 23 is inserted into the transverse sleeve 22b with both ends protruding from the transverse sleeve 22b for easy operation with both hands. In addition, the lever 23 can be a telescopic lever with adjustable length, so that the length of the lever 23 can be changed as needed to provide a larger lever arm.
[0080] The first end of the winch 40 is connected to the upper end of the spinal support plate 11 of the casualty support unit 10; the second end of the winch 40 is connected to the winch support frame.
[0081] The corner support unit 30 is used to fix the winch 40 at the position where it needs to be turned, such as the corner of the edge of the bunker.
[0082] The corner support unit 30 includes a C-shaped elastic plate 31 and a curved cylinder 32. The curved cylinder 32 is fixed to the upper side of the C-shaped elastic plate 31, and sharp teeth 34 are formed at both ends of the lower side of the C-shaped elastic plate 31. Handles 33a and 33b are formed at both ends of the C-shaped elastic plate. The handles 33a and 33b are used to help open the C-shaped elastic plate 31, and the corner support unit 30 is engaged and fixed to the corner of the edge of the shelter by the sharp teeth 34. The winch 40 passes through the curved cylinder 32, reducing the friction of the winch at the corner position, thereby providing a smooth transition at the corner position.
[0083] In use, a shelter (e.g., a wall) is pre-selected. Then, a fixing strip is inserted behind the shelter using fixing pins to secure the winch unit. The second end of the winch is then fixed to the winch support frame. The rescuer, holding the first end of the winch, along with the folded casualty carrier unit and the winch, reaches the casualty's location. After unfolding the casualty carrier unit, the casualty is placed onto it and secured using securing straps (which can be integrally attached to the casualty carrier unit). After loading the casualty, the first end of the winch is fixed to the top of the casualty carrier unit. The rescuer then quickly moves behind the shelter and rotates the winch unit using a winch lever, continuously winding the winch onto the winch support frame. During winding, if significant resistance is encountered, the winch can be wound onto the second or fourth sub-segments. If the edge of the shelter's supporting winch exerts significant friction on the winch, corner support units can be pre-engaged and fixed at that point to reduce winch friction. As the winch became increasingly entangled, the casualty carrier unit, carrying the wounded, was eventually pulled behind the bunker, at which point the wounded could be treated.
