Description

Technical Field

[0001] This invention relates to the field of trauma hemostasis technology, specifically to a hemostasis device for emergency trauma. Background Technology

[0002] Traumatic hemostasis refers to the emergency procedures that stop blood flow and control blood loss after bleeding is caused by ruptured blood vessels due to external injury, using physical or pharmacological methods. It is the most basic means of trauma first aid and aims to prevent hemorrhagic shock and save lives.

[0003] Currently, most trauma hemostasis devices rely on ordinary straps or Velcro to secure the device to the limb, thus ensuring the stability of the hemostasis operation. However, in actual emergency use, the straps and Velcro are prone to loosening, slippage, or even falling off due to factors such as patient limb movement, wound bleeding and lubrication, and external traction. This causes the hemostasis device to shift, resulting in inaccurate compression position and insufficient pressure, thus affecting the hemostasis effect. To address these issues, the inventors have proposed an emergency trauma hemostasis device to solve these problems. Summary of the Invention

[0004] To address the problem of bandages easily becoming loose, the present invention aims to provide a hemostatic device for emergency trauma.

A winding rod is rotatably installed inside the storage box. A connecting strip is fixedly installed on the outer surface of the winding rod, and the end of the connecting strip away from the winding rod is fixedly connected to the connecting block. A limit gear is fixedly installed on one end of the winding rod. A movable rod is slidably installed inside one side of the storage box, and the movable rod is close to the winding rod.

[0006] Preferably, the pressurization mechanism includes a mounting frame, an airbag is detachably mounted inside the mounting frame, a pressure plate is slidably mounted inside the mounting frame, and the lower surface of the pressure plate is in contact with the upper surface of the airbag. Rotating bars are rotatably mounted on both sides of the upper surface of the mounting frame, and the top end of the rotating bar movably passes through the pressure plate, with the lower surface of the rotating bar in contact with the upper surface of the pressure plate.

[0007] Preferably, an injection tube is fixedly installed inside the pressure plate, and the bottom end of the injection tube movably passes through the airbag, while the top end of the airbag's injection tube movably passes through the pressure plate. Both the top ends of the airbag and the injection tube are equipped with sealing plugs.

[0008] Preferably, the clamping mechanism includes a fixed frame, and the upper surface of the fixed frame and the lower surface of the mounting frame are fixedly connected. Clamping plates are slidably installed on both sides of the fixed frame. A hemostatic sponge pad is detachably installed between the two clamping plates. Two No. 1 springs are fixedly installed on the sides of the two clamping plates that are close to each other, and the end of the No. 1 spring away from the clamping plate is fixedly connected inside the fixed frame.

[0009] Preferably, the installation mechanism includes installation plates, and four installation plates are fixedly installed on both sides of the installation frame. Limiting rods are slidably installed in each of the four installation plates, and the bottom ends of the limiting rods are movably inserted into the storage box and the connecting block.

[0010] Preferably, a limiting plate is fixedly installed on the outer surface of the bottom end of the limiting rod, and a circular groove is opened in each of the four mounting plates. The limiting plate is rotated and locked inside the circular groove. A second spring is provided in each of the four mounting plates, and the bottom end of the second spring is in contact with the upper surface of the limiting plate.

[0011] Preferably, both ends of the winding rod are fixedly installed with No. 3 springs, and the ends of the two No. 3 springs that are far apart from each other are fixedly connected inside the storage box.

[0012] Preferably, a guide plate is fixedly installed on the outer surface of the moving rod, and the guide plate is slidably disposed inside the storage box. A No. 5 spring is fixedly installed on the side of the guide plate, and the end of the No. 5 spring away from the guide plate is fixedly connected to the inside of the storage box.

[0013] Preferably, two limiting frames are fixedly installed on the side of the storage box, and a limiting strip is rotatably installed on the end of the moving rod away from the winding rod, and the limiting strip is rotatably locked inside the limiting frame.

[0014] Preferably, each of the two limiting frames has a positioning post slidably installed inside it, and one end of the positioning post is movably locked inside the limiting strip.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This invention relies on a connecting mechanism to lock and limit the connecting strap, preventing it from loosening and slipping due to limb movement during emergency treatment, thus improving the overall binding stability of the device. Combined with a pressure mechanism, it can achieve physical pressure hemostasis by inflating the airbag and squeezing the hemostatic sponge pad, and can also inject hemostatic agents into the hemostatic sponge pad through the injection tube, achieving a dual hemostatic effect of physical compression and drug coagulation, significantly improving the efficiency of wound hemostasis.

[0016] 2. This invention employs a locking structure in which a limiting gear and a limiting toothed disc mesh with each other to lock the winding rod, preventing the connecting strap from loosening after binding. The matching limiting strip and limiting frame work together to limit the connection, preventing the limiting toothed disc from arbitrarily adhering to the limiting gear and causing the connecting strap to be unable to be pulled open. At the same time, the energy storage and rebound of the No. 3 spring drives the winding rod to rotate, completing the automatic binding of the connecting strap, simplifying the medical staff's binding operation and shortening the time for emergency fixation.

[0017] 3. This invention utilizes a limiting rod to connect a limiting storage box and a connecting block, enabling quick assembly and disassembly of the connecting mechanism. This facilitates the individual replacement of the connecting mechanism after damage or contamination. At the same time, the limiting plate, in conjunction with the circular groove, limits the circumferential movement of the limiting rod, preventing it from being loosened or accidentally dislodged by vibration or external force, thus improving the stability of the device.

[0028] 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.

[0029] Example: Figure 1-8 As shown, the present invention provides a hemostatic device for emergency trauma, including a pressure mechanism 1. The lower surface of the pressure mechanism 1 is provided with a clamping mechanism 2 for installing a hemostatic pad, which is used to install the hemostatic pad and realize the installation and removal of the hemostatic pad. The two sides of the pressure mechanism 1 are provided with a strap installation mechanism 3 for installing the strap, which is used to facilitate the removal and replacement of the strap. The installation mechanism 3 is provided with a connection mechanism 4 for connecting with the patient's limb, which is used to connect the device with the patient's limb and prevent the device from moving during use. The connecting mechanism 4 includes a storage box 401 and a connecting block 402. A winding rod 403 is rotatably installed inside the storage box 401. A connecting belt 404 is fixedly installed on the outer surface of the winding rod 403, and the end of the connecting belt 404 away from the winding rod 403 is fixedly connected to the connecting block 402. A limiting gear 406 is fixedly installed on one end of the winding rod 403. A moving rod 407 is slidably installed inside one side of the storage box 401. A limiting gear 411 is fixedly installed on the end of the moving rod 407 near the winding rod 403, and the limiting gear 406 is movably locked inside the limiting gear 411 to limit the winding rod 403. In use, the movement of the moving rod 407 drives the limiting gear 411 to move, so that the limiting gear 411 and the limiting gear 406 mesh. At this time, the limiting gear 406 is limited by the limiting gear 411, thereby limiting the winding rod 403.

[0030] The pressurization mechanism 1 includes a mounting frame 101, in which an airbag 103 is detachably mounted. A pressure plate 102 is slidably mounted in the mounting frame 101, with its lower surface in contact with the upper surface of the airbag 103. Rotating bars 105 are rotatably mounted on both sides of the upper surface of the mounting frame 101, with the top end of the rotating bars 105 movably penetrating the pressure plate 102. The lower surface of the rotating bars 105 is in contact with the upper surface of the pressure plate 102, thus limiting the position of the airbag 103. In use, the pressure plate 102 is inserted, so that its lower surface contacts the upper surface of the airbag 103, limiting the position of the airbag 103. At the same time, when the pressure plate 102 is inserted, the top end of the rotating bars 105 penetrates the pressure plate 102. At this time, rotating the rotating bars 105 causes their lower surface to contact the upper surface of the pressure plate 102, limiting the position of the pressure plate 102.

[0031] By adopting the above technical solution, the pressure plate 102 can limit the airbag 103.

[0032] An injection tube 104 is fixedly installed inside the pressure plate 102, and the bottom end of the injection tube 104 movably passes through the airbag 103. The top end of the airbag 103's air injection tube movably passes through the pressure plate 102. Both the top ends of the air injection tube and the injection tube 104 are equipped with sealing plugs for inflating the airbag 103. In use, the airbag 103 is inflated by contacting the air injection tube of the airbag 103 through an auxiliary device.

[0033] By adopting the above technical solution, the air injection tube can be used to inflate the airbag 103.

[0034] The clamping mechanism 2 includes a fixed frame 201, and the upper surface of the fixed frame 201 is fixedly connected to the lower surface of the mounting frame 101. Clamping plates 203 are slidably installed on both sides of the fixed frame 201. A hemostatic sponge pad 202 is detachably installed between the two clamping plates 203. Two No. 1 springs 204 are fixedly installed on the sides of the two clamping plates 203 that are close to each other. The end of the No. 1 spring 204 away from the clamping plate 203 is fixedly connected to the inside of the fixed frame 201 for installing the hemostatic sponge pad 202. In use, the clamping plates 203 are pushed away from each other. At this time, the top of the hemostatic sponge pad 202 is placed between the two clamping plates 203. At this time, the deformation force is released by the No. 1 spring 204, pushing the two clamping plates 203 closer together to clamp the hemostatic sponge pad 202 and complete the installation of the hemostatic sponge pad 202.

[0035] By adopting the above technical solution, the clamp 203 can be used to install the hemostatic sponge pad 202.

[0036] The mounting mechanism 3 includes mounting plates 301, and four mounting plates 301 are fixedly mounted on both sides of the mounting frame 101. Limiting rods 302 are slidably installed in each of the four mounting plates 301, and the bottom end of the limiting rod 302 is movably inserted into the storage box 401 and the connecting block 402 to limit the storage box 401 and the connecting block 402. In use, when the bottom end of the limiting rod 302 is inserted into the storage box 401 or the connecting block 402, the storage box 401 and the connecting block 402 are limited by the limiting rod 302.

[0037] By adopting the above technical solution, the limiting rod 302 can limit the storage box 401 and the connecting block 402.

[0038] A limiting plate 303 is fixedly installed on the outer surface of the bottom end of the limiting rod 302. Each of the four mounting plates 301 has a circular groove, and the limiting plate 303 is rotatably locked inside the circular groove. Each of the four mounting plates 301 has a second spring 304, and the bottom end of the second spring 304 is in contact with the upper surface of the limiting plate 303 to limit the limiting rod 302. In use, when the limiting plate 303 is rotatably locked inside the circular groove, the limiting rod 302 is limited by the limiting plate 303.

[0039] By adopting the above technical solution, the limiting plate 303 can limit the limiting rod 302.

[0040] Both ends of the winding rod 403 are fixedly installed with No. 3 springs 405, and the ends of the two No. 3 springs 405 that are far apart from each other are fixedly connected inside the storage box 401 to drive the winding rod 403 to rotate. When in use, when the No. 3 springs 405 release the deformation force, the winding rod 403 is driven to rotate through the No. 3 springs 405.

[0041] By adopting the above technical solution, the No. 3 spring 405 can drive the winding rod 403 to rotate.

[0042] A guide plate 413 is fixedly installed on the outer surface of the moving rod 407, and the guide plate 413 is slidably disposed inside the storage box 401. A No. 5 spring 412 is fixedly installed on the side of the guide plate 413, and the end of the No. 5 spring 412 away from the guide plate 413 is fixedly connected to the inside of the storage box 401 to drive the moving rod 407 to move. In use, when the No. 5 spring 412 releases the deformation force, the No. 5 spring 412 pushes the guide plate 413 to move, and the movement of the guide plate 413 drives the moving rod 407 to move.

[0043] By adopting the above technical solution, the No. 5 spring 412 can drive the moving rod 407 to move.

[0044] Two limiting frames 414 are fixedly installed on the side of the storage box 401. A limiting strip 408 is rotatably installed on the end of the moving rod 407 away from the winding rod 403, and the limiting strip 408 is rotatably locked inside the limiting frame 414 to limit the moving rod 407. When in use, when the limiting strip 408 is rotatably locked inside the limiting frame 414, the moving rod 407 is limited by the limiting strip 408.

[0045] By adopting the above technical solution, the limiting strip 408 can limit the movement rod 407.

[0046] Positioning posts 409 are slidably installed inside both limiting frames 414, and one end of the positioning post 409 is movably locked inside the limiting strip 408. A No. 4 spring 410 is fixedly installed on the side of the two positioning posts 409 away from the limiting strip 408, and the end of the No. 4 spring 410 away from the positioning post 409 is fixedly connected to the inside of the limiting frame 414 to limit the limiting strip 408. In use, when one end of the positioning post 409 is locked inside the limiting strip 408, the limiting strip 408 is limited by the positioning post 409.

[0047] By adopting the above technical solution, the positioning post 409 can limit the limiting strip 408.

[0048] Working principle: First, the connecting strap 404 is pulled outward. During the pulling process, the No. 3 spring 405 undergoes elastic deformation under force, and the unfolded connecting strap 404 is wrapped around the outside of the patient's wounded limb. The hemostatic sponge pad 202 at the bottom of the pressure plate 102 is precisely aligned with the wound position. Then, the connecting strap 404 is released. The deformed No. 3 spring 405 releases its elastic restoring force, which drives the winding rod 403 to rotate and automatically wind up and tighten the connecting strap 404, so that the connecting strap 404 fits tightly against the patient's limb skin, completing the initial positioning and binding of the device. Next, rotate the limiting strip 408 to make it rotate out and disengage from the limiting slot of the limiting frame 414, thereby releasing the locking limit on the moving rod 407. After the limit is released, the No. 5 spring 412, which is in a compressed deformation state, releases its elastic force and pushes the guide plate 413 to move forward. The guide plate 413 simultaneously drives the moving rod 407 to move axially. The moving rod 407 further drives the limiting gear plate 411 to move, so that the limiting gear plate 411 meshes with the limiting gear 406. By engaging the limiting gear 406 with the limiting gear plate 411, the rotational freedom of the limiting gear 406 is restricted, thereby locking the rotation of the winding rod 403. This achieves locking and positioning of the wound connecting strip 404, preventing the connecting strip 404 from loosening and slipping, and ensuring the binding stability. Then, gas is injected into the airbag 103 through the external air inlet tube, causing the airbag 103 to gradually expand. The pressure generated by the expansion of the airbag 103 evenly squeezes the hemostatic sponge pad 202 below, making the hemostatic sponge pad 202 tightly adhere to and compress the wound surface, achieving physical pressure hemostasis. At the same time, hemostatic agents are delivered into the device through the drug injection tube 104. The hemostatic agents evenly soak the hemostatic sponge pad 202 along the tube, allowing the hemostatic agents to fully contact the wound surface. Through the dual effects of drug coagulation and physical compression, the efficiency of wound hemostasis is improved, and the time for emergency hemostasis is shortened. Finally, when it is necessary to replace, clean, or maintain the connecting mechanism 4, the limiting rod 302 can be rotated to drive the limiting plate 303 to rotate synchronously, causing the limiting plate 303 to rotate out of the circular limiting groove of the equipment and release the structural lock. At this time, the second spring 304, which is in a deformed state, releases its elastic thrust, pushing the limiting plate 303 and the limiting rod 302 to move as a whole, so that the bottom end of the limiting rod 302 quickly disengages from the limiting hole of the storage box 401 and the connecting block 402, releasing the assembly limit of the storage box 401 and the connecting block 402, and the connecting mechanism 4 can be directly disassembled as a whole, realizing the quick disassembly and replacement of the connecting mechanism 4.

[0049] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
