Description

Technical Field

[0001] The present application relates to the field of medical devices, and in particular to a quick-connect single-person rescue stretcher device. Background Art

[0002] With the global economic integration, maritime trade between countries has increased, leading to an increasing number of offshore operations. Furthermore, operations in confined spaces, such as underground, are often difficult, labor-intensive, and time-consuming. We must recognize that while economic and social development continues, humanity also faces a range of dangers and challenges that threaten human safety and health. However, economic development must always prioritize people. When emergencies occur, timely care and transportation of injured individuals becomes increasingly critical. Confined spaces present a significant challenge for medical treatment systems, demanding greater speed, precision, and efficiency. After primary care, injured individuals are transported to rear-line medical facilities by vehicles and other transportation equipment for further treatment. During this process, patient transport primarily relies on stretchers, making their suitability for these confined environments crucial for timely treatment. However, the transport of injured individuals is subject to numerous limitations due to factors such as narrow spaces, steep passages, small turning radiuses, and obstacles in the passages. Existing stretchers are not well adapted to narrow environments due to their length, the large number of people required, the difficulty of ascending and descending slopes, and the large turning radius required. Consequently, existing stretchers cannot effectively meet the needs of rapid rescue and transport of injured individuals in confined spaces. Furthermore, existing stretchers are not suitable for single-person operation and are difficult to connect to rescuers wearing exoskeletons. Therefore, existing rescue devices are not suitable for single-person rescue operations.

[0003] Although researchers have made many beneficial improvements, due to the different heights of different rescuers, coupled with the influence of the narrow space and the uneven and harsh environment of the ground, the existing structure still finds it difficult to quickly adapt to the different back height requirements of the stretcher under the above-mentioned environmental conditions and the need for rapid separation and connection between the stretcher and the rescuer by a single person.

[0147] In order to make the invention purpose, technical solution and beneficial effects of this application clearer, this application is further described below with reference to the accompanying drawings and specific embodiments. It should be understood that the embodiments are only used to explain this application and are not used to limit the scope of the application.

[0148] After extensive exploration and research, the inventor of this application discovered a quick-connect single-person backpack rescue stretcher device, and completed this application on this basis.

[0149] This application provides a quick-connect single-person rescue stretcher device, such as Figure 1 As shown, the device comprises an exoskeleton assembly 3 and a variable angle stretcher 4 connected in sequence, wherein the exoskeleton assembly 3 and the variable angle stretcher 4 are detachably connected via an impact-type connector 2. The device also comprises a harness 1 for assisting in fixing the exoskeleton assembly 3 and the variable angle stretcher 4.

[0150] like Figure 2 As shown, the exoskeleton assembly 3 includes a waist mechanism 31, and the two sides of the waist mechanism 31 are respectively connected to the active driving hip 33, the adjustable thigh 34, the elastic extension calf 35 and the foot plate 36. Figure 3 As shown, the waist mechanism 31 includes a waist support plate 311 and waist sliders 316 disposed on either side of the waist support plate 311, with the waist sliders 316 and the waist support plate 311 being slidably connected. The waist mechanism 31 also includes a first fastener 315 for securing the waist sliders 316 and the waist support plate 311. The waist mechanism 31 is adjustable in width and is secured by the first fastener 315 to accommodate exoskeleton wearers (i.e., rescuers) of varying body widths. The waist mechanism 31 is symmetrical about the waist support plate 311. In a specific embodiment of the present application, the waist mechanism 31 is a C-shaped bilaterally symmetrical structure. The actively driven hip section 33 is provided with a first slide rail 317, along which the waist mechanism 31 can slide. The waist mechanism 31 also includes a second fastener 37 for securing the actively driven hip section 33 and the waist mechanism 31. The waist slider 316 can slide along the first slide rail 317 and further includes a waist slot 314. The second fastener 37 locks the waist mechanism 31 to the active-driven hip 33 through the waist-long hole 314. In a specific embodiment of the present application, the second fastener 37 can be, for example, a screw that passes through the waist-long hole 314 to lock the waist mechanism 31 at a certain distance from the active-driven hip 33 to accommodate exoskeleton wearers (i.e., rescuers) of different body thicknesses. The waist slider 316 is provided with a waist belt hole 313 at one end away from the waist support plate 311, and a waist strap is connected to the waist belt hole 313. The exoskeleton assembly 3 is worn by the rescuer to reduce the rescuer's load and provide auxiliary power.

[0151] like Figure 2As shown, the actively driven hip section 33 includes a motor that can drive the adjustable thigh section 34 to rotate, driving the adjustable thigh section 34 to swing freely in the sagittal plane of the human body, providing external force for the hip flexion and extension of the wearer of the exoskeleton assembly (i.e., the rescuer). The upper end of the adjustable thigh section 34 is provided with a sagittal axis-oriented rotation axis that is movably connected to the actively driven hip section 33, so that the adjustable thigh section 34 can swing freely and unrestricted in the frontal plane of the human body, so that this structure does not restrict the extension and contraction movement of the wearer's thigh. The actively driven hip section 33 is provided with a buckle 32. The buckle 32 is connected to the strap 1.

[0152] like Figure 2 As shown, the adjustable thigh section 34 includes a thigh length adjustment mechanism 343, which is equipped with a thigh strap 341. The thigh length adjustment mechanism 343 includes a first thigh section and a second thigh section. The second thigh section is capable of sliding and retracting relative to the first thigh section. The first thigh section is provided with a plurality of thigh through holes 3431, and the second thigh section is provided with a thigh protrusion that mates with the thigh through holes 3431. This allows the length of the adjustable thigh section 34 to be adjusted to accommodate exoskeleton wearers (i.e., rescuers) of different thigh lengths. In a specific embodiment of the present application, during thigh length adjustment, when the second thigh section is extended to a desired position relative to the first thigh section, the corresponding thigh protrusion can be extended from the thigh through hole 3431, thereby fixing the position of the first and second thigh sections. If further adjustment is required, the thigh protrusion can be pressed into the thigh through hole 3431 to facilitate the sliding of the second thigh section within the first thigh section. The thigh protrusion is elastic.

[0153] like Figure 2 As shown, the elastically extensible calf portion 35 includes a calf length adjustment mechanism 351, which is provided with a calf strap 352. The calf length adjustment mechanism 351 includes a first calf portion and a second calf portion, wherein the second calf portion is capable of sliding and retracting relative to the first calf portion. The first calf portion is provided with a plurality of calf through-holes 3511, and the second calf portion is provided with a calf protrusion that cooperates with the calf through-holes 3511, thereby making the length of the elastically extensible calf portion 35 adjustable to accommodate exoskeleton wearers (i.e., rescuers) with different calf lengths. In a specific embodiment of the present application, during the process of adjusting the calf length, when the second calf portion is extended to a suitable position relative to the first calf portion, the calf protrusion at the corresponding position can be extended from the calf through-holes 3511, thereby fixing the positions of the first and second calf portions. When further adjustment is required, the calf protrusion can be pressed into the calf through-holes 3511 to facilitate the sliding of the second calf portion within the first calf portion. The calf protrusion is also an elastic protrusion.

[0154] like Figure 2As shown, the adjustable thigh portion 34 and the elastically extendable calf portion 35 are movably connected. In a specific embodiment of the present application, the adjustable thigh portion 34 and the elastically extendable calf portion 35 can be connected, for example, via a rotating shaft. A gas spring 342 is provided between the adjustable thigh portion 34 and the elastically extendable calf portion 35 to counteract the flexion of the elastically extendable calf portion 35, thereby providing a counterforce to the flexion of the knee joint of the exoskeleton wearer (i.e., the rescuer), thereby providing an extension force to the rescuer's knee, thereby facilitating the rescuer's knee extension movement.

[0155] In a specific embodiment of the present application, the foot plate 36 and the elastic extensible calf portion 35 can be, for example, fixedly connected or movably connected, for example, connected by a rotating shaft; when the two are fixedly connected, the foot plate 36 is in the shape of a round rod, so that the sole of the foot of the wearer of the exoskeleton assembly (i.e., the rescuer) can rotate back and forth relative to the foot plate 36; when the two are connected by a rotating shaft, the foot plate 36 can have a certain width to avoid causing local pressure concentration on the sole of the foot. The foot plate 36 is provided with a foot strap 362 and a kick-assisting pin 361. The kick-assisting pin 361 provides additional assisting force for the wearer of the exoskeleton assembly (i.e., the rescuer) to push off the ground, and has the function of slowing down the rigid collision of the exoskeleton assembly 3 when it touches the ground, thereby providing a cushioning force when the rescuer's foot touches the ground.

[0156] The waist mechanism 31, the adjustable thigh part 34, the elastic extensible calf part 35 and the foot plate 36 are respectively provided with a waist strap, a thigh strap 341, a calf strap 352 and a foot strap 362, which are used to fix the wearer of the exoskeleton assembly (i.e., the rescuer), so that the exoskeleton assembly 3 and the rescuer are integrated to better reduce the load on the rescuer's joints and transmit the force applied by the variable angle stretcher 4 to the ground through the exoskeleton assembly 3.

[0157] like Figure 3 、 Figure 6 、 Figure 7 and Figure 8 As shown, the exoskeleton component 3 and the impact-type connector 2 are connected via a first connecting component. The first connecting component includes a gourd hole 222 and a hook 312. The gourd hole 222 is provided on the impact-type connector 2, and the hook 312 is provided on the waist mechanism 31. In a specific embodiment of the present application, the hook 312 can be, for example, T-shaped, and can pass through the cavity of the gourd hole 222 and extend out, and be fixed at the upper end of the gourd hole 222, so that the impact-type connector 2 is connected to the waist mechanism 31.

[0158] like Figure 8The impact-type connector 2 includes a guide base 22 and guide plates 227 disposed on either side of the guide base 22. The impact-type connector 2 is symmetrically arranged about the guide base 22. The impact-type connector 2 is used to quickly connect the variable-angle stretcher 4 and the exoskeleton assembly 3, making the present invention suitable for single-person rescue operations, freeing the rescuer's hands and not restricting the rescuer's running or jumping.

[0159] like Figure 8 The guide seat 22 is provided with a plurality of pressing holes 226 in the middle. In a specific embodiment of the present application, the first fastener 315 can be pressed against the pressing hole 226, thereby connecting and fixing the waist mechanism 31 and the guide seat 22 so that they are not loose and prevent the two from being separated.

[0160] like Figure 4 、 Figure 5 and Figure 6 As shown, the variable angle stretcher 4 and the impact type connecting seat 2 are connected by a second connecting assembly. The guide plate 227 and the variable angle stretcher 4 are respectively provided with a second connecting assembly. The variable angle stretcher 4 includes a trunk section 42, a hip section 44 and a leg section 46 that are hinged in sequence. The trunk section 42 is provided with a support plate 41. The support plate 41 is connected to the impact type connecting seat 2 through a second connecting assembly. A plurality of support hole plates 412 are provided in the middle of the support plate 41, and the support hole plates 412 can, for example, be provided at different heights of the support plate 41. In a specific embodiment of the present application, the openings of the support plate holes 412 are facing the direction of the hip section 44. When the variable angle stretcher 4 is placed vertically on the ground, the openings of the support plate holes 412 face downwards. A plurality of rows of holes 411 are provided on the support plate 41. The rows of holes 411 are connected to the strap 1.

[0161] The second connecting assembly includes a floating ratchet plate 27 and a support plate hole 412 that cooperates with the floating ratchet plate 27. Figure 11As shown, the floating spine plate 27 includes a guide sleeve 271, a base plate 272, and a spine 273 connected in sequence. The spine 273 extends in a direction away from the guide sleeve 271 and forms an inclined angle with the base plate 272. The direction in which the spine 273 extends is opposite to the opening direction of the support plate hole 412, so that the spine 273 can be locked in a one-way connection with the support plate hole 412 on the support plate 41. In a specific embodiment of the present application, the support plate hole 412 can be, for example, an arc-shaped hemisphere. When the spine 273 contacts it, the spine 273 can abut against the inner surface of the arc-shaped hemisphere, thereby allowing the variable angle stretcher 4 to be stably connected to the impact-type connector 2 under gravity conditions, thereby making it convenient for the rescuer to adjust the height of the variable angle stretcher 4 on his back, thereby changing the height of the variable angle stretcher 4 relative to the ground. The second connecting assembly can be used to insert the thorns 273 into the back plate holes 412 at different heights according to the ground and other environmental conditions, so as to adjust the height of the stretcher, thereby adjusting the different back height requirements of the stretcher relative to the rescuer. Figure 7 As shown, the guide plate 227 is symmetrical on both sides and opens outward, and is used to guide the direction of the support plate 41 when it is pressed toward the floating spine plate 27 of the impact type connecting seat 2, so as to reduce the difficulty of alignment and enable the variable angle stretcher 4 to be quickly connected to the impact type connecting seat 2.

[0162] like Figure 6 、 Figure 7 and Figure 8 As shown, the guide base 22 includes a guide post 221, which is sheathed with an elastic member 21. The floating ratchet plate 27 is movably connected to the guide base 22 via the elastic member 21. In a specific embodiment of the present application, the elastic member 21 may be, for example, a spring. The elastic member 21 forces the floating ratchet plate 27 to move away from the guide base 22. The elastic member 21 presses against the base plate 272, ensuring that the floating ratchet plate 27 is always pressed against the support plate 41 of the angle-variable stretcher 4 to which it is connected.

[0163] like Figure 8 As shown, the guide plate 227 is provided with a slotted hole 223, which is externally connected to a self-locking seat 224 and a pivot seat 225. The pivot seat 225 is provided with a pivot 2251 and a lower torsion spring hole 2252. The impact-type connecting seat 2 also includes a striker-type locking tongue 26, which is movably mounted in the slotted hole 223 and movably connected to the pivot of the pivot seat 225.

[0164] like Figure 8 As shown, the outside of the slot 223 is connected to a self-locking seat 224. Figure 7 The impact type connection seat 2 further includes a pin 24, which is movably connected to the self-locking seat 224. Figure 10As shown, the strike-type lock bolt 26 has a guide piece 263 at one end near the slot 223, and a separate stopper 265 and a striker 266 at the other end away from the slot 223. The guide piece 263 is provided with an upper torsion spring hole 261, a lock hole 262, and a rotation hole 264. The rotation hole 264 is adapted to fit over the pivot 2251. The strike-type lock bolt 26 is mounted on the pivot 2251 on the pivot seat 225 via the rotation hole 264, concealed within the slot 223 of the guide seat 22, with only the striker 266 exposed.

[0165] like Figure 9 As shown, the pin 24 includes a pin head 241, a top plate 242, a bolt rod 243, and a handle plate 244, which are connected in sequence. The pin 24 is inserted into the self-locking seat 224 via the bolt rod 243. The bolt rod 243 is provided with a top spring 23, which is located between the self-locking seat 224 and the top plate 242. The top spring 23 is used to allow the pin head 241 of the pin 24 to be exposed from the self-locking seat 224. When the impact head 266 of the impact bolt 26 is rotated due to the impact of the back plate 41, the pin head 241 of the pin 24 is automatically inserted into the locking hole 262 under the guidance of the guide plate 263 to lock the impact bolt 26.

[0166] like Figure 6 As shown, a torsion spring 25 is provided on the pivot seat 225, and the two ends of the torsion spring 25 are respectively fixedly installed in the upper torsion spring hole 261 and the lower torsion spring hole 2252, so as to pop out the impact lock tongue 26 when the pin 24 is separated from the lock hole 262, thereby releasing the support plate 41, so that the variable angle stretcher 4 can be removed from the floating ratchet plate 27.

[0167] In a specific embodiment of the present application, the impact-type lock tongue 26 is movably mounted in the slot 223 via a pivot seat 225. When the impact-type lock tongue 26 rotates to a certain position, the pin 24 engages with the impact-type lock tongue 26, thereby locking the rotation of the impact-type lock tongue 26. When the support plate 41 approaches the impact-type connecting seat 2, the support plate hole 412 of the support plate 41 contacts and press-fits with the thorn 273 on the floating ratchet plate 27, which causes the thorn 273 to penetrate the support plate hole 412, thereby hanging the support plate 41 on the floating ratchet plate 27. The support plate 41 further presses the floating ratchet plate 27, which will continue to drive the impact-type lock tongue 26 and eventually be locked by the pin 24. The stop head 265 of the impact-type lock tongue 26 will prevent the support plate 41 from retreating unless the pin 24 is released.

[0168] In a specific embodiment of the present application, when the back plate 41 of the variable-angle stretcher 4 is pressed against the floating ratchet plate 27, the back plate 41 will hit the collision head 266 and drive the impact lock tongue 26 to rotate around the pivot 2251 of the pivot seat 225. At this time, the guide plate 263 contacts and flattens the pin head 241, causing the pin head 241 to retract into the bolt hole of the self-locking seat 224. When the lock hole 262 is close to the aligned bolt hole, the pin bolt 24 pops out the pin head 241 again under the drive of the top spring 23 and inserts it into the lock hole 262, thereby locking the impact lock tongue 26. The impact lock tongue 26 rotates, causing the stop head 265 to press against the other side of the back plate 41, thereby limiting the retreat of the back plate 41. When the variable-angle stretcher 4 needs to be unlocked, the pin 24 is pulled to unlock the impact lock tongue 26, and the support plate 41 can push the stopper 265 backward to drive the impact lock tongue 26 to rotate, and then drive the floating ratchet plate 27 downward relative to the support plate 41, so that the variable-angle stretcher 4 can be separated from the waist mechanism 31.

[0169] like Figure 7 and Figure 8 As shown, the guide column 221 includes a guide column 2212 and a guide cap 2211 connected to each other. Figure 11 As shown, the guide sleeve 271 includes a large hole 2711. The guide sleeve 271 cooperates with the guide post 221 to limit the position of the floating ratchet plate 27. Specifically, a small hole 2712 is provided within the large hole 2711. The large hole 2711 and the small hole 2712 match the dimensions of the guide cap 2211 and the guide post 2212, respectively, to enable the floating ratchet plate 27 to move forward and backward relative to the guide seat 22. The guide cap 2211 is larger than the small hole 2712, preventing the floating ratchet plate 27 from separating from the guide post 221 and falling.

[0170] In the quick-connect single-person rescue stretcher device provided by this application, Figure 4 As shown, the variable-angle stretcher 4 also includes an upward angle adjustment portion 43, which includes a trunk connector 421, a first hip connector 441, and an upward angle adjustment rod 431. The trunk connector 421 and the upward angle adjustment rod 431 are lockably connected. The first hip connector 441 is rotatably connected to the upward angle adjustment rod 431. The trunk 42 and hip 44 are rotatably connected, and the angle between them can be adjusted and locked using the upward angle adjustment rod 43.

[0171] like Figure 4 As shown, the variable-angle stretcher 4 also includes a lowering angle adjustment portion 47, which includes a leg section connector 461, a second hip section connector 442, and a lowering angle adjustment rod 471. The leg section connector 461 is lockably connected to the lowering angle adjustment rod 471. The second hip section connector 442 is rotatably connected to the lowering angle adjustment rod 471. The hip section 44 and leg section 46 are rotatably connected, and the angle between them can be adjusted and locked by the lowering angle adjustment rod 47.

[0172] In the specific embodiments of this application, Figure 4As shown, the side of the upper angle rod 431 is provided with multiple upper angle rod through holes, and the side of the lower angle rod 471 is provided with multiple lower angle rod through holes. The trunk segment connector 421 is provided with a trunk segment protrusion that matches the upper angle rod through holes, and the leg segment connector 461 is provided with a leg segment protrusion that matches the lower angle rod through holes. In a specific embodiment of the present application, when the upper angle rod 431 moves to a suitable position, the trunk protrusion at the corresponding position can be extended into the through hole of the upper angle rod to lock the relative movement of the upper angle rod; when the lower angle rod 471 moves to a suitable position, the leg protrusion at the corresponding position can be extended from the through hole of the lower angle rod and locked. When further adjustment is required, the trunk protrusion or the leg protrusion can be pulled up to disengage from the through hole, thereby facilitating the sliding of the upper angle rod 431 or the lower angle rod 471, facilitating the adjustment of the angle of the variable angle stretcher 4, and correspondingly changing the angle between the torso, thigh and calf of the injured person thereon, thereby changing the posture of the injured person. The length of the adjustable variable angle stretcher 4 can be adapted to meet the needs of different narrow space environments and different patient first aid situations. The variable angle stretcher 4 is used to fix and transport the injured person, minimizing their secondary injuries, so as to facilitate timely transfer and subsequent treatment.

[0173] like Figure 4 As shown, the trunk section 42, hip section 44, and leg section 46 are each provided with a cloth plate 48 for the injured person to sit or lie down and to support the injured person's body. The cloth plate 48 is also provided with a binding strap (not shown) for securing the head, neck, torso, and legs of the injured person to prevent them from rolling or moving and causing secondary injury.

[0174] The hip section 44 also includes a cross brace 45. The cross brace 45 is located near the leg section 46. In the embodiment of the present application, the cross brace 45 is located at the lower end of the hip section 44 and is connected to the hip sections 44 on both sides to strengthen the hip sections 44 and prevent them from being deformed due to excessive force.

[0175] In a specific embodiment of the present application, the exoskeleton assembly 3 can be quickly connected to the variable-angle stretcher 4 through the impact-type connecting seat 2. Specifically, the impact-type connecting seat 2 is pre-connected with the waist mechanism 31 installed on the exoskeleton assembly 3 through the T-shaped nail 312, and collides with the back plate 41 of the variable-angle stretcher 4, colliding with the impact-type lock tongue 26 and the floating ratchet plate 27 of the impact-type connecting seat 2, so that the back plate 41 is pressed against the floating ratchet plate 27 and connected thereto, thereby completing the purpose of hanging the variable-angle stretcher 4 on the waist mechanism 31 of the exoskeleton assembly 3, and finally making the variable-angle stretcher 4 and the exoskeleton assembly 3 form a quick-connect mechanism.

[0176] In addition, the quick-connect single-person rescue stretcher device provided by the present application may also include a pair of small wheels. The small wheels are provided at one end of the lowering angle rod 471 away from the second hip section connector 442, and are used to reduce the resistance of the variable angle stretcher 4 against the ground when it is dragged, so that the variable angle stretcher 4 can change its angle (for example, Figure 12 The angle shown is not 90°, and the dragging rescue is performed when the casualty is lying on one side with one end touching the ground.

[0177] In the quick-connect single-person rescue stretcher device provided by this application, Figure 1 As shown, the strap 1 is used to tighten the variable-angle stretcher 4 to the rescuer's back to further stabilize the movement of the variable-angle stretcher 4 and make the load more stable. The strap 1 is equipped with an adjustment buckle for length adjustment and fixation. The strap 1 is equipped with strap hooks at both ends, which are removably hooked to the buckle 32 and the row of holes 411, respectively. The strap hook can be, for example, a rotating hook; more specifically, the rotating hook can be, for example, a horn hook. The horn hook is equipped with a safety buckle to prevent it from falling off. In a specific embodiment of the present application, the strap 1 can have multiple straps, for example, two straps. The two straps 1 cross in front of the rescuer's chest to fix the variable-angle stretcher 4 to the wearer (i.e., the rescuer), playing a stabilizing role, allowing the variable-angle stretcher 4 to move with the rescuer, making the rescuer feel integrated, and preventing the variable-angle stretcher 4 from shaking too far away from the rescuer's body when the road conditions are complex, causing the rescuer to lose their center of gravity or increase the rescuer's energy consumption.

[0178] In the quick-connect single-person rescue stretcher device provided by this application, Figure 16 As shown, a third connecting assembly 6 is further provided between the guide seat 22 and the waist mechanism 31. The third connecting assembly 6 includes a first connecting head 61, a second connecting head 62 and an intermediate connecting portion 63. The first connecting head 61 and the second connecting head 62 are rotatably connected to the intermediate connecting portion 63 respectively. The first connecting head 61 is fixed on the guide seat 22. The second connecting head 62 is fixed on the waist mechanism 31. In a specific embodiment of the present application, the intermediate connecting portion 63 can be, for example, a double torsion spring, a rubber pad, etc., which can enable a pair of connecting heads 61 and 62 to maintain a certain original angle, and can provide resistance to the inclination angle of the guide seat 22, thereby preventing hard collision between the guide seat 22 and the waist mechanism 31.

[0179] like Figure 13 As shown, the quick-connect single-person back-carrying rescue stretcher device provided by the present application further includes wheel legs 5, for example, four wheel legs. The wheel legs 5 are respectively installed on both sides of the two ends of the variable angle stretcher 4, that is, installed on the upper section of the torso section 42 and the lower section of the leg section 46. Figure 14 and Figure 15As shown, the wheel leg 5 includes a stopper 51, a sleeve 52, a support leg 53 and a wheel 54 connected in sequence. The stopper 51 is fixed on the variable angle stretcher 4. The sleeve 52 is sleeved on the variable angle stretcher 4, and the end of the sleeve 52 away from the stopper 51 is provided with a plurality of bayonet holes 521, for example, there can be two bayonet holes. The wheel leg also includes a stopper pin mechanism 55 that cooperates with the bayonet hole 521. The stopper pin mechanism 55 is provided with a stopper pin 551 and a spring 552. In a specific embodiment of the present application, when the wheel leg 5 is installed on the lower section of the leg section 46, the leg section 46 is provided with a long hole slot 462, and the stopper pin 551 and the spring 552 are both installed in the middle of the leg section 46 and the stopper pin 551 extends from the long slot hole 462. One end of the spring 552 is fixed in the long slot 462, and the other end pushes the stop pin 551 to slide and translate in the long slot 462, pressing against the bayonet 521 on the sleeve 52 to lock the wheel leg 5. In a specific embodiment of the present application, under normal conditions, the stop pin of the stop pin mechanism 55 presses against the sleeve 52 and is stuck in the bayonet 521. The sleeve 52 can be rotated by pulling the stop pin. After reaching another position, the stop pin is released, and the sleeve 52 is rotated to align with the other bayonet 521. Under the action of the spring, the sleeve 52 is re-locked to prevent it from rotating, thereby achieving at least two positions of the wheel leg 5, so that the wheel leg 5 can be folded or lowered to allow the wheel 54 to contact the ground, and ultimately achieving the function of fast flat ground movement of the variable angle stretcher 4 in a flat state.

[0180] The use of the quick-connect single-person rescue stretcher device provided in this application is as follows:

[0181] 1) If Figure 1 If the variable angle stretcher 4 is set at 90 degrees, the injured person sits on the variable angle stretcher 4, and the rescuer completely carries the patient on his back for rescue, which is suitable for rescue in an environment with stairs or extremely poor road conditions.

[0182] 2) If Figure 12 If the included angle between the three sections of the variable angle stretcher 4 is set to about 135 degrees, the injured person is half lying on the variable angle stretcher 4, and one end of the variable angle stretcher 4 is on the ground. At this time, the rescuer carries the other end of the variable angle stretcher 4 and drags the patient for rescue. It is suitable for single-person fast walking rescue on flat ground such as in good road conditions, narrow aisles with a slight slope, wide spaces, and flat ground.

[0183] 3) If Figure 13 When the variable angle stretcher 4 is separated from the exoskeleton assembly 3, the variable angle stretcher 4 can be pushed by one person; when the variable angle stretcher 4 is laid flat, it can also be carried by two or more people for rescue; when the wheel legs 5 are lowered to the ground, it can be suitable for fast running rescue on flat ground.

[0184] In a specific embodiment of the present application, the exoskeleton assembly 3 is combined with the variable angle stretcher 4 to rescue the patient in the following manner:

[0185] First, place the patient on the variable angle stretcher 4 and secure it, then stand the variable angle stretcher 4 upright, or place it against a wall, or hold the variable angle stretcher 4 with your hands, or connect one end of the two straps 1 to the variable angle stretcher 4 and cross them over the rescuer's shoulders in front of the chest and then connect them to the buckle 32.

[0186] Afterwards, the rescuer wearing the exoskeleton assembly 3 and the variable-angle stretcher 4 face each other back to back. When the rescuer's back is as centered as possible against the center of the variable-angle stretcher 4, the rescuer leans back and then upwards to press against the back plate 41 behind the variable-angle stretcher 4 to connect the variable-angle stretcher 4. At this time, a metallic collision sound can be heard as the top plate 242 of the pin 24 hits the self-locking seat 224.

[0187] Then, the rescuer squats or slowly lifts up the angle-variable stretcher 4 to adjust the height of the angle-variable stretcher 4 on the rescuer's back.

[0188] Finally, adjust the length of the two straps 1.

[0189] In summary, the quick-connect single-person backpack rescue stretcher device described in the present invention can quickly assemble and adjust the height of the stretcher relative to the rescuer's back and lock it in one direction, so as to adapt to the fast-response and fast-paced modern medical treatment and transfer in confined spaces and complex environments.
