Abstract
Description
Technical Field
[0001] This invention relates to the field of auxiliary hemostasis devices, specifically an emergency auxiliary hemostasis device for patients with coagulation disorders. Background Technology
[0002] Coagulation dysfunction refers to a group of diseases caused by congenital or acquired factors that lead to a deficiency or abnormal function of coagulation factors or insufficient platelet count or dysfunction, resulting in a decline in hemostasis and coagulation function.
[0003] When these patients experience trauma, surgery, or spontaneous bleeding, their blood has difficulty clotting normally, resulting in rapid and prolonged bleeding that can easily lead to hemorrhagic shock, multiple organ failure, or even death. Therefore, an emergency auxiliary hemostasis device for patients with coagulation disorders is proposed. Summary of the Invention
[0004] The purpose of this invention is to provide an emergency auxiliary hemostasis device for patients with coagulation dysfunction, so as to solve the problems mentioned in the background art.
[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: This invention relates to an emergency auxiliary hemostasis device for patients with coagulation dysfunction, comprising a fixing plate, a drug delivery mechanism disposed inside the fixing plate, a compression mechanism disposed at the bottom of the fixing plate, a fixing mechanism disposed at the bottom of the fixing plate, the drug delivery mechanism including a hemostasis component disposed at the bottom of the fixing plate, and a locking component disposed at the top of the fixing plate. Furthermore, the hemostatic assembly includes a fixed frame, which is fixedly connected to the inner side of a fixed plate. A fixed sleeve is fixedly connected to the top of the fixed frame, and a rotating sleeve is rotatably connected to the inner wall of the fixed sleeve. Two sliding rails are fixedly connected to the inner wall of the fixed frame, and a sliding plate is slidably connected between the two sliding rails. Each of the two sliding plates has a sliding groove. A second fixed plate is fixedly connected to the bottom of each of the two sliding plates. Two telescopic rods are fixedly connected to the opposite sides of each of the two second fixed plates. The opposite sides of several telescopic rods are fixedly connected to the inner wall of the fixed frame. A spring is installed on the outer surface of each of the several telescopic rods. A hemostatic sponge is fixedly connected to the bottom of the fixed frame. A driving component is provided at the bottom of the rotating sleeve. The two sliding plates are symmetrically arranged with the fixed sleeve as the center.
[0006] Furthermore, the locking assembly includes a support plate, which is fixedly connected to the outer surface of the fixed sleeve. A locking rod is slidably connected inside the support plate. A limiting plate is fixedly connected to the outer surface of the locking rod. The limiting plate is a circular plate and limits the locking rod. A spring is installed on the outer surface of the locking rod. A handle is fixedly connected to the side of the locking rod away from the support plate. A locking groove is opened on the back of the rotating sleeve. A sealing cover is installed on the top of the fixed sleeve. Dustproof pads are installed on the inner walls of both grooves. The locking rods are both circular rods, and the outer surface of the locking rods contacts the inner wall of the locking groove.
[0007] Furthermore, the compression mechanism includes two hollow shells, both of which are fixedly connected to the bottom of a fixed plate. A sliding rod is slidably connected to the bottom of each of the two hollow shells, and a pneumatic plate is fixedly connected to the top of each of the two sliding rods. All internal components of the two hollow shells are identical. Two springs are fixedly connected to the top of each of the two pneumatic plates, and the tops of several springs are fixedly connected to the bottom of the fixed plate. Two compression airbags are connected between the two hollow shells. Rubber compression pads are rotatably connected to the bottom of each of the two sliding rods. Both pneumatic plates are rectangular and adapted to the inner walls of the two hollow shells. Both rubber compression pads are arc-shaped.
[0008] Furthermore, the fixing mechanism includes a fixing strap, which is fixedly connected to the left side of the fixing plate. Two elastic rods are fixedly connected to the right side of the fixing strap. Each of the two elastic rods has a locking block fixedly connected to the side away from the fixing strap, and the two locking blocks are symmetrically arranged with the fixing strap as the center.
[0009] Furthermore, a second fixing strap is fixedly connected to the bottom right side of the fixing plate, and an insertion frame is fixedly connected to the outer surface of the second fixing strap. The insertion frame has limit grooves on both the front and back sides, and the two locking blocks are rectangular in shape, with both locking blocks contacting the inside of the two limit grooves.
[0010] Furthermore, the driving component includes a rotating ring, which is rotatably connected to the inner wall of the fixed sleeve. The top of the rotating ring is fixedly connected to the bottom of the rotating sleeve, and two slide rods are fixedly connected to the bottom of the rotating ring. The rotating ring slides in the grooves on the two sliding plates through the two slide rods.
[0011] The present invention has the following beneficial effects: (1) The present invention sets up a hemostatic component, specifically, when the rotating sleeve rotates, it drives the rotating ring to rotate, and the sliding rod at the bottom slides in the sliding groove, pushing the sliding plate to separate to both sides along the sliding track. The fixed plate then squeezes the telescopic rod and the spring, releasing the drug in the fixed sleeve. After the release is completed, the rotating sleeve is released. Under the elastic reset action of the telescopic rod and the spring, the fixed plate and the sliding plate approach each other, sealing the bottom of the fixed sleeve, improving the utilization efficiency of the hemostatic drug, and quickly forming a hemostatic environment.
[0012] (2) The present invention sets up a compression mechanism. Specifically, when the fixing plate is fixed to the wound, it will first be in contact with the bleeding site by the rubber compression pad. Then, the slide rod 2 will slide adaptively with the contour of the bleeding site, driving the air pressure plate to move up and down in the hollow shell. The air pressure plate squeezes the spring 3 and, in conjunction with the air pressure inside the hollow shell, causes the compression airbag to expand, so that the blood vessels at the wound site generate uniform and continuous compression force, effectively slowing down the blood flow rate and reducing secondary damage such as blood vessel damage and tissue necrosis caused by local pressure concentration.
[0013] (3) The present invention sets up a fixing mechanism, specifically by attaching the rubber compression pad at the bottom of the fixing plate to the bleeding area, pulling the fixing strap one through the insertion frame on the fixing strap two, causing the elastic rod to deform elastically, driving the card block to be inserted into the limiting groove of the insertion frame, thus completing the rapid fixing of the device. The flexible design of the fixing strap one and the fixing strap two can adapt to different limb contours, reducing the impact on local blood circulation.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0018] Please see Figures 1-11As shown, this invention is an emergency auxiliary hemostasis device for patients with coagulation dysfunction, including a fixing plate 1, a drug delivery mechanism 2 disposed inside the fixing plate 1, a compression mechanism 3 disposed at the bottom of the fixing plate 1, and a fixing mechanism 4 disposed at the bottom of the fixing plate 1. The drug delivery mechanism 2 includes a hemostasis component 21 disposed at the bottom of the fixing plate 1 and a locking component 22 disposed at the top of the fixing plate 1. The hemostasis component 21 includes a fixing frame 211 fixedly connected to the inside of the fixing plate 1, and a fixing sleeve 212 fixedly connected to the top of the fixing frame 211. The inner wall of the fixing sleeve 212 is rotatably connected to... The device includes a rotating sleeve 213, and two sliding rails 214 fixedly connected to the inner wall of a fixed frame 211. A sliding plate 215 is slidably connected between the two sliding rails 214. Each sliding plate 215 has a groove 216. A second fixed plate 217 is fixedly connected to the bottom of each sliding plate 215. Two telescopic rods 218 are fixedly connected to the opposite sides of each fixed plate 217. The opposite sides of several telescopic rods 218 are fixedly connected to the inner wall of the fixed frame 211. Springs 219 are installed on the outer surfaces of several telescopic rods 218. A hemostatic sponge 2193 is fixedly connected to the bottom of the fixed frame 211. A driving component is provided at the bottom of the rotating sleeve 213. The two sliding plates 21... 5. Symmetrically arranged around the fixed sleeve 212, the locking assembly 22 includes a support plate 221, which is fixedly connected to the outer surface of the fixed sleeve 212. A locking rod 222 is slidably connected inside the support plate 221. A limit plate 223 is fixedly connected to the outer surface of the locking rod 222. The limit plate 223 is a circular plate that limits the locking rod 222. A spring 224 is installed on the outer surface of the locking rod 222. A handle 225 is fixedly connected to the side of the locking rod 222 away from the support plate 221. A locking groove 226 is provided on the back of the rotating sleeve 213. A sealing cover 227 is installed on the top of the fixed sleeve 212. Dustproof pads 228 are installed on the inner walls of both grooves 216. All rods 222 are circular rods. The outer surface of the locking rod 222 contacts the inner wall of the locking groove 226. Specifically, when the rotating sleeve 213 rotates, it drives the rotating ring 2191 to rotate. The sliding rod 2192 at its bottom slides in the sliding groove 216, pushing the sliding plate 215 to separate to both sides along the sliding track 214. The fixing plate 217 then squeezes the telescopic rod 218 and the spring 219, releasing the drug in the fixing sleeve 212. After the release is completed, the rotating sleeve 213 is released. Under the elastic reset action of the telescopic rod 218 and the spring 219, the fixing plate 217 and the sliding plate 215 move closer to each other, sealing the bottom of the fixing sleeve 212, improving the utilization efficiency of the hemostatic drug, and quickly forming a hemostatic environment.
[0019] The compression mechanism 3 includes two hollow shells 311, both of which are fixedly connected to the bottom of the fixed plate 1. A slide rod 312 is slidably connected to the bottom of each hollow shell 311, and a pneumatic plate 313 is fixedly connected to the top of each slide rod 312. The internal components of the two hollow shells 311 are identical. Two springs 314 are fixedly connected to the top of each pneumatic plate 313, and the tops of several springs 314 are fixedly connected to the bottom of the fixed plate 1. Two compression airbags 315 are connected between the two hollow shells 311. Rubber compression pads 316 are rotatably connected to the bottom of each slide rod 312. Both pneumatic plates 313 are rectangular plates. The system is configured such that both air pressure plates 313 are adapted to the inner walls of the two hollow shells 311, and both rubber pressure pads 316 are arc-shaped. Specifically, when the fixing plate 1 is fixed to the wound, it will first fit against the bleeding site with the rubber pressure pads 316, and then the slide rod 2 312 will slide adaptively with the contour of the bleeding site, causing the air pressure plates 313 to move up and down inside the hollow shells 311. The air pressure plates 313 compress the spring 3 and, in conjunction with the air pressure inside the hollow shells 311, cause the pressure bladder 315 to expand, so that the blood vessels at the wound site generate uniform and continuous pressure, effectively slowing down the blood flow rate and reducing secondary damage such as vascular damage and tissue necrosis caused by local pressure concentration.
[0020] The fixing mechanism 4 includes a first fixing strap 411, which is fixedly connected to the left side of the first fixing plate 1. Two elastic rods 412 are fixedly connected to the right side of the first fixing strap 411. Each elastic rod 412 has a locking block 413 fixedly connected to the side away from the first fixing strap 411. The two locking blocks 413 are symmetrically arranged with the first fixing strap 411 as the center. A second fixing strap 414 is fixedly connected to the bottom right side of the first fixing plate 1. An insertion frame 415 is fixedly connected to the outer surface of the second fixing strap 414. Limiting grooves 416 are provided on both the front and back of the insertion frame 415. Both locking blocks 413 are rectangular in shape and both locking blocks 413 are in contact with the inside of the two limiting grooves 416. Specifically, the rubber compression pad 316 at the bottom of the fixing plate 1 is attached to the bleeding area, and the fixing strap 1 411 is pulled through the insertion frame 415 on the fixing strap 2 414. The elastic rod 412 undergoes elastic deformation, which drives the locking block 413 to be inserted into the limiting groove 416 of the insertion frame 415, thus completing the quick fixation of the device. The flexible design of the fixing strap 1 411 and the fixing strap 2 414 can adapt to different limb contours and reduce the impact on local blood circulation.
[0021] The driving component includes a rotating ring 2191, which is rotatably connected to the inner wall of the fixed sleeve 212. The top of the rotating ring 2191 is fixedly connected to the bottom of the rotating sleeve 213. Two slide rods 2192 are fixedly connected to the bottom of the rotating ring 2191. The rotating ring 2191 slides in the grooves 216 on the two sliding plates 215 through the two slide rods 2192.
[0022] In use, the device is first fixed to the patient's bleeding site using the fixing mechanism 4: the rubber compression pad 316 at the bottom of the fixing plate 1 is placed against the bleeding area, and the fixing strap 1 411 is pulled through the insertion frame 415 on the fixing strap 2 414. The elastic rod 412 undergoes elastic deformation, causing the locking block 413 to engage in the limiting groove 416 of the insertion frame 415, thus completing the quick fixing of the device. The flexible design of the fixing strap 1 411 and the fixing strap 2 414 can adapt to different limb contours, avoiding affecting local blood circulation. Furthermore, during disassembly, simply press the locking block 413 inside the two limiting grooves 416 to bring them closer together and release them from the limiting grooves 416 to unlock the fixing strap 1 411 and the fixing strap 2 414. During fixing, the device... The frame 211 will first come into contact with the outside of the wound. The hemostatic sponge 2193 at its bottom can prevent wound infection and prevent blood leakage. Then, the person can hold the handle 225 and pull the locking rod 222, which will cause the limiting plate 223 to compress the second spring 224, so that the locking rod 222 disengages from the locking groove 226 on the rotating sleeve 213, releasing the fixation of the rotating sleeve 213. At this time, the rotating sleeve 213 can be rotated, causing the rotating ring 2191 at the bottom to rotate. Since the two sliding rods 2192 are fixed to the bottom of the rotating ring 2191 and slide in the two sliding grooves 216, when the rotating ring 2191 rotates, it will cause the two sliding rods 2192 at its bottom to slide in the sliding grooves 216 of the sliding plate 215, thus... The two sliding plates 215 are pushed away from each other along the sliding track 214. At the same time, the sliding plates 215 cause the fixed plate 217 to press against the telescopic rod 218 and the spring 219. As the two sliding plates 215 move away from each other, the drug inside the rotating sleeve 213 is released. After the release is complete, the user can release the rotating sleeve 213. At this time, under the elastic action of the telescopic rod 218 and the spring 219, the two fixed plates 217 are moved closer together, which in turn causes the two sliding plates 215 to move closer together, sealing the bottom of the fixed sleeve 212. At this time, the user releases the handle 225, and under the elastic force of the spring 224, pushes the locking rod 222 to reset and lock into the locking groove 226. At this time, the position of the fixed rotating sleeve 213 is fixed. The device is positioned to ensure stable drug release and prevent the sliding plate 215 from loosening and causing drug leakage. The sealing cover 227 prevents the drug inside the fixing sleeve 212 from being infected. The dustproof pad 228 prevents impurities from entering the slide groove 216 and affecting the movement of the sliding plate 215. At the same time, when the fixing plate 1 is fixed to the wound, it will first fit against the bleeding site with the rubber compression pad 316. Then, the sliding rod 212 will slide adaptively with the contour of the bleeding site, driving the air pressure plate 313 to move up and down in the hollow shell 311. The air pressure plate 313 compresses the spring 3 and, in conjunction with the air pressure inside the hollow shell 311, causes the compression airbag 315 to expand, generating uniform and continuous pressure on the blood vessels at the wound site, reducing blood flow and avoiding secondary damage caused by excessive local pressure.
