Description

Technical Field

[0001] The present invention relates to the technical field of field combat rescue, and particularly relates to a multifunctional field combat rescue device. Background Art

[0002] Field combat rescue refers to the emergency medical treatment and evacuation operations for injured military personnel in a battlefield environment. Such rescue activities usually occur during or just after a battle. Rescue personnel (such as military doctors, combat lifeguards, etc.) need to quickly assess the condition of the wounded under gunfire, an uncertain safety environment, and limited resources, provide on-site first aid, such as hemostasis, bandaging, cardiopulmonary resuscitation, etc., and at the same time ensure that the wounded are quickly evacuated from the battlefield to a safe area or medical facility for further treatment. Field combat rescue requires rescue personnel to have excellent first aid skills, quick judgment, and strong psychological qualities to save the lives of comrades under extreme pressure.

[0003] Among the existing rescue equipment, the backpack stretcher is widely used due to its portability and practicality. However, the existing backpack stretcher has certain design defects: there is no effective limiting mechanism at both the head and foot ends of the stretcher, which makes it easy for the wounded to slide up or down during transportation. This kind of sliding not only causes discomfort to the wounded, but may also cause the wounded to fall off the stretcher in severe cases, resulting in secondary injuries. In addition, when there is only one medical staff on the scene, due to the lack of a convenient pulling mechanism, the medical staff will face great operational difficulties when moving the wounded, affecting the rescue efficiency and safety. Therefore, in view of these problems, it is necessary to improve the existing backpack stretcher to enhance its stability and operational convenience. Summary of the Invention

[0004] An object of the present invention is to provide a multifunctional field combat rescue device to solve the problems in the above background that there is no effective limiting mechanism at both the head and foot ends of the stretcher, which makes it easy for the wounded to slide up or down during transportation. This kind of sliding not only causes discomfort to the wounded, but may also cause the wounded to fall off the stretcher in severe cases, resulting in secondary injuries. In addition, when there is only one medical staff on the scene, due to the lack of a convenient pulling mechanism, the medical staff will face great operational difficulties when moving the wounded, affecting the rescue efficiency and safety.

[0005] A multifunctional field combat rescue device according to an embodiment of the present invention includes:

[0006] A backpack mechanism, installed on one side of the stretcher mechanism, for enabling medical staff to conveniently carry the entire rescue device on their backs and move in the wild; the backpack mechanism includes an outer package and an inner package, and one side of the inner package is fixedly connected to one side inside the outer package;

[0007] A stretcher mechanism is installed on one side of the backpack mechanism to achieve the telescopic function of the stretcher, making the stretcher more portable. The stretcher mechanism includes a fixed stretcher and a sliding stretcher, and the sliding stretcher is movably connected to the inside of the fixed stretcher.

[0008] A first limiting mechanism is installed on the surface of the backpack mechanism and is used to limit the position of the wounded person's head.

[0009] The first limiting mechanism includes a first magic tape and a second magic tape. The first magic tape is fixedly connected to the surface of the inner bag body, and the second magic tape is fixedly connected to the surface of the fixed stretcher.

[0010] A second limiting mechanism is installed at the lower part of the sliding stretcher and is used to limit the position below the feet of the wounded person.

[0011] The second limiting mechanism includes a limiting plate and a rack. The rack is fixedly connected to the inner surface of the fixed stretcher. A first gear is rotatably connected to the inner surface of the sliding stretcher. A second gear and a third gear are rotatably connected to one side of the first gear through a rotating shaft. On the other side inside the sliding stretcher, a fourth gear is rotatably connected through a rotating rod. The limiting plate is fixedly connected to the side surface of the rotating rod. The fourth gear and the third gear are mutually driven by a transmission belt.

[0012] One end of the sliding stretcher is rotatably connected with a moving wheel through a connecting block.

[0013] Preferably, a storage space is provided inside the outer bag body. The inner surface of the storage space is fixedly connected with a small medicine bag, a large medicine bag, a handle storage bag, and a syringe storage bag respectively, which are used to store small medicines, large medicines, the handle body, and disposable syringes respectively.

[0014] Preferably, the sides between the outer bag body and the inner bag body are connected to each other by a zipper. Straps are fixedly connected to both side surfaces of the outer bag body, and buckles are fixedly connected to the surfaces of the straps through connecting bands.

[0015] Preferably, handle bodies are threadedly connected to one side surface of both the fixed stretcher and the sliding stretcher, which are convenient for manually lifting the stretcher mechanism.

[0016] Preferably, sliding grooves are provided inside the fixed stretcher. Sliding blocks are fixedly connected to both side surfaces of the sliding stretcher, and the sliding stretcher is slidably connected to the inside of the fixed stretcher through the sliding blocks.

[0017] Preferably, card slots are provided at both ends of the side surface of the fixed stretcher. A groove is provided on one side surface of the sliding block, and a clamping block is movably connected to the inside of the groove through a first spring.

[0018] Preferably, a third limiting mechanism for locking the position of the clamping block is installed on the outer surface of the fixed stretcher. The third limiting mechanism includes a limiting rod and a handle, and the handle is fixedly connected to the surface of the limiting rod.

[0019] Preferably, a limiting groove is formed on the outer surface of the fixed stretcher, the limiting rod is slidably connected inside the limiting groove, and a second spring is arranged between the two side surfaces of the handle and the inner wall of the limiting groove.

[0020] Preferably, both side surfaces of the clamping block are inclined surfaces, and through holes are formed through the side surfaces of the clamping block.

[0021] Preferably, a flexible plate is movably connected to the upper surface of the sliding stretcher through a third spring. When the sliding stretcher is in the retracted state, the flexible plate is compressed. When the sliding stretcher is pulled out, the flexible plate is ejected by the third spring so that the sliding stretcher and the fixed stretcher are on the same horizontal plane, so that the wounded will not feel discomfort when lying on the stretcher.

[0022] The beneficial effects of the present invention are as follows:

[0023] Through the first limiting mechanism and the second limiting mechanism provided in the present invention, when it is necessary to transfer the wounded through the stretcher mechanism, during the process of pulling out the sliding stretcher from the inside of the fixed stretcher to the limit and locking the position, the first gear slides in the direction of the rack along with the sliding stretcher. When the first gear slides to the position of the rack, the first gear rotates through the meshing effect of the rack, the first gear drives the second gear to rotate in the reverse direction, so that the third gear rotates in the reverse direction, and the third gear drives the fourth gear to rotate through the transmission belt, so that the rotating rod and the limiting plate rotate out towards the upper surface of the sliding stretcher. Until the position of the sliding stretcher slides to the limit and is locked, the limiting plate is perpendicular to the sliding stretcher to limit the position below the feet of the wounded. Then, the zipper is opened, and the inner package is turned up from the inside of the outer package and attached to the surface of the fixed stretcher. The position of the outer package is fixed by the mutual adhesion between the first magic tape and the second magic tape. When the wounded lies flat on the stretcher mechanism, the head can be rested on the outer package to limit the position of the wounded's head, effectively preventing the wounded from sliding on the stretcher, ensuring the safety and stability of the wounded during the transfer process, and at the same time providing comfortable support for the head, greatly improving the convenience of rescue operations and the safety guarantee of the wounded;

[0024] Through the third limiting mechanism provided in the present invention, when the sliding stretcher is pulled out to the extreme position, the clamping block is ejected from the groove by the elastic force of the first spring and is clamped into the internal card slot. At the same time, the limiting rod is slid in the opposite direction of the clamping block through the handle of the third limiting mechanism, so that the clamping block is completely clamped into the internal card slot. Then, the handle is released, and the limiting rod is inserted into the through hole of the clamping block by the reset elastic force of the second spring to realize the locking of the clamping block, and finally the locking of the position between the sliding stretcher and the fixed stretcher is realized, making the overall structure of the stretcher mechanism more stable when transferring the wounded by the stretcher. When the sliding stretcher is retracted, after the sliding stretcher is slid to the innermost end inside the fixed stretcher, the limiting rod is pulled in the opposite direction of the clamping block through the handle. After the clamping block is completely clamped into the card slot at the other end, the handle is released, and the limiting rod is inserted into the through hole of the clamping block by the reset elastic force of the second spring to realize the locking of the positions of the clamping block and the sliding block at this time, making the structure of the sliding stretcher and the fixed stretcher stable when retracted, ensuring the stability of the stretcher when unfolded and retracted, effectively preventing the accidental movement of the stretcher components, and improving the reliability of the stretcher operation and the safety of the wounded transportation;

[0025] Through the backpack mechanism provided in the present invention, the medical staff can conveniently carry the rescue device on their backs through the backpack straps of the backpack mechanism. Through the storage space inside the outer package body, it is convenient to store small medicines, large medicines, disposable syringes and the handle body, increasing the overall functionality of the field combat rescue device. Through the provided buckles, the medical staff can connect the backpack straps on both sides through the buckles when carrying the device, making the device more stable when carried on the back.

The outer surface of the fixed stretcher 201 is provided with a third limiting mechanism 5 for locking the position of the block 207. The third limiting mechanism 5 includes a limiting rod 502 and a handle 503. The handle 503 is fixedly connected to the surface of the limiting rod 502. A limiting groove 501 is provided on the outer surface of the fixed stretcher 201. The limiting rod 502 is slidably connected to the inside of the limiting groove 501. A second spring 504 is provided between the two side surfaces of the handle 503 and the inner wall of the limiting groove 501. Both side surfaces of the block 207 are inclined surfaces. A through hole 208 is provided through the side surface of the block 207. Through the first limiting mechanism 3 and the second limiting mechanism 4, when the wounded needs to be transferred by the stretcher mechanism 2, the sliding stretcher 202 is pulled downward from the inside of the fixed stretcher 201 to the limit and locked in the position, the first gear 402 moves with the sliding stretcher 202 toward the rack 40 1, when the first gear 402 slides to the position of the rack 401, the first gear 402 rotates due to the meshing effect of the rack 401, and the first gear 402 drives the second gear 403 to rotate in the opposite direction, thereby causing the third gear 405 to rotate in the opposite direction, and the third gear 405 drives the fourth gear 407 to rotate through the transmission belt 408, so that the rotating rod 406 and the limiting plate 409 are rotated toward the upper surface of the sliding stretcher 202.

Then, the zipper 111 is opened, and the inner bag 107 is turned upward from the inside of the outer bag 101 and attached to the surface of the fixed stretcher 201. The position of the outer bag 101 is fixed by the mutual adhesion between the first Velcro 301 and the second Velcro 302.When the wounded lies flat on the stretcher mechanism 2, the head can be rested on the outer package body 101, which limits the position of the wounded's head, effectively prevents the wounded from sliding on the stretcher, ensures the safety and stability of the wounded during the transfer process, and at the same time provides comfortable support for the head, greatly improving the convenience of rescue operations and the safety guarantee of the wounded. Through the set third limiting mechanism 5, when the sliding stretcher 202 is pulled out to the extreme position, the clamping block 207 is ejected from the groove 206 by the elastic force of the first spring 209 and is clamped into the internal card slot 205. At the same time, the limiting rod 502 is slid in the opposite direction of the clamping block 207 through the handle 503 of the third limiting mechanism 5, so that the clamping block 207 is completely clamped into the internal card slot 205. Then the handle 503 is released, and the limiting rod 502 is inserted into the through hole 208 of the clamping block 207 by the reset elastic force of the second spring 504, realizing the locking of the clamping block 207, and finally realizing the locking of the position between the sliding stretcher 202 and the fixed stretcher 201, making the overall structure of the stretcher mechanism 2 more stable when transferring the wounded by the stretcher. When the sliding stretcher 202 is retracted, after the sliding stretcher 202 is slid to the innermost end inside the fixed stretcher 201, the limiting rod 502 is pulled in the opposite direction of the clamping block 207 through the handle 503. After the clamping block 207 is completely clamped into the card slot 205 at the other end, the handle 503 is released, and the limiting rod 502 is inserted into the through hole 208 of the clamping block 207 by the reset elastic force of the second spring 504, realizing the locking of the positions of the clamping block 207 and the sliding block 204 at this time, making the structure of the sliding stretcher 202 and the fixed stretcher 201 stable when retracted, ensuring the stability of the stretcher when unfolded and retracted, effectively preventing accidental movement of the stretcher components, and improving the reliability of stretcher operation and the safety of wounded transportation.

[0045] During use, check the backpack mechanism 1 and the stretcher mechanism 2 to ensure that all components are in good condition and firmly connected. Then, open the zipper 111 between the outer bag body 101 and the inner bag body 107, place the small medicine, large medicine, the handle body 6, and the disposable syringe into the corresponding storage bags respectively, and fix the inner bag body 107 inside the outer bag body 101. Adjust the shoulder strap 108 and pass through it, fix it with the buckle 110 to stably carry the backpack mechanism 1 on the body. Next, take out the stretcher mechanism 2, unfold and fix the stretcher 201, pull out the sliding stretcher 202 to the required length, and use the handle 503 of the third limiting mechanism 5 to slide the limiting rod 502 in the opposite direction of the clamping block 207, so that the clamping block 207 is completely inserted into the inside of the clamping groove 205. Then release the handle 503, and insert the limiting rod 502 into the through hole 208 of the clamping block 207 through the reset elastic force of the second spring 504 to lock the clamping block 207 and ensure the stability of the stretcher when unfolded. Place the wounded on the stretcher smoothly, fix the head, carry the backpack mechanism 1 on the back and push the stretcher to transfer the wounded to a safe area. Finally, retract the sliding stretcher 202, slide it to the innermost end inside the fixed stretcher 201, pull the limiting rod 502 to the opposite direction of the clamping block 207 through the handle 503. After the clamping block 207 is completely inserted into the clamping groove 205 at the other end, release the handle 503, and insert the limiting rod 502 into the through hole 208 of the clamping block 207 through the reset elastic force of the second spring 504 to lock the positions of the clamping block 207 and the sliding block 204 at this time, so as to ensure the stability of the structure of the sliding stretcher 202 and the fixed stretcher 201 when retracted. Place the stretcher mechanism 2 back on one side of the backpack mechanism 1 and close the zipper 111 to ensure that all items are fixed securely. This process ensures the convenience, safety, and stability of the rescue device during use.
