Abstract
Description
Technical Field
[0001] The present invention belongs to the technical field of medical devices, and in particular relates to a hemostatic device for emergency use. Background Art
[0002] There are mainly the following types of hemostatic devices for emergency use: Tourniquet: including rubber tourniquet, cassette tourniquet, inflatable tourniquet, rotary tourniquet, etc., which stop bleeding by compressing blood vessels to block blood flow, and are suitable for bleeding caused by large blood vessel injuries in the limbs; Hemostatic dressing: such as Band-aids, sterile dressings, hemostatic dressings, etc., which can directly cover wounds, promote coagulation, and resist infection; Hemostatic clips: such as the titanium clips used in on-site first aid hemostatic devices, which achieve the purpose of stopping bleeding by clamping blood vessels.
[0003] Currently, hemostatic devices widely used in clinical and emergency scenarios (such as traditional rubber tourniquets, snap-on tourniquets, and some rotary tourniquets) have exposed significant limitations in actual applications. Existing devices mostly rely on fixed-size designs or single physical compression methods (such as tightening or inflation), making it difficult to achieve precise fit and stable compression on limbs of different thicknesses (such as children's thin limbs, adults' thick limbs, or localized swelling). This leads to displacement of the compression position or uneven pressure distribution, affecting the hemostatic effect. In addition, traditional tourniquets are prone to displacement due to limb flexion when used near joints, while dressings or gauze that rely solely on manual pressure have difficulty maintaining continuous and stable pressure. This is especially true in resource-limited environments such as pre-hospital emergency care or disaster sites, where emergency personnel need to complete hemostatic operations in a short period of time. Summary of the Invention
[0004] The purpose of the present invention is to provide an emergency hemostatic device to solve the problem in the above background technology that the existing emergency hemostatic devices cannot quickly compress and stop bleeding on wounds on the limbs, and cannot adjust the pressure force according to the thickness of the limbs.

[0019] Compared with the prior art, the present invention has the following beneficial effects:
[0020] (1) The present invention provides a rotating handle, a mounting plate, a first rotating rod and a transmission mechanism, so that when performing a rapid hemostasis operation on an injured limb, the movable mechanism is first placed on the torso part that needs to stop bleeding. Then, by rotating the rotating handle, the rotating teeth are engaged with the first meshing teeth, thereby driving the second meshing teeth to rotate synchronously. This transmission design can cause the first rotating rod to rotate, and through the linkage between the hinged rod and the second rotating rod, the clamping plate moves inward, thereby quickly clamping the patient's torso part. This structure not only facilitates the adjustment of the clamping force and improves the hemostasis efficiency, but also provides a stable and uniform pressure distribution to ensure that the clamping is firm and reliable.

If the clamping effect needs to be enhanced for a thinner torso, the inflatable tube can be inserted into the sealed connection port to achieve a fixed connection between the inflatable tube and the inflatable airbag; then, a syringe is used to inject gas into the inflatable airbag through piston movement to expand it and apply greater pressure to the target hemostasis site. This design enables the device to adapt to torso parts of different sizes, achieve effective clamping and hemostasis, and further improve the hemostasis efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0030] Example 1:
[0031] See also Figures 1-6 As shown, a first aid hemostatic device comprises:
[0032] Housing cover 1;
[0033] A rotating handle 2 is provided at the top of the outer shell 1;
[0034] The clamping mechanism 3 is arranged inside the outer shell 1;
[0035] Movable mechanism 4, the movable mechanism 4 is fixedly connected to the outside of one side of the clamping mechanism 3, the movable mechanism 4 includes a connecting plate 401, a rotating shaft 402 and a rotating sleeve 403, the top of the connecting plate 401 is fixedly connected to the rotating shaft 402, the outer sleeve of the rotating shaft 402 is provided with a rotating sleeve 403, one side of the rotating sleeve 403 is fixedly connected to a pressure plate 404, the rotating sleeve 403 is rotatably connected to the outside of the rotating shaft 402, the pressure plate 404 is a semi-arc structure, the pressure plate 404 is rotatably connected to the outside of the rotating shaft 402 through the rotating sleeve 403, the movable mechanism 4 is symmetrically arranged in two groups, the inner side wall of the movable mechanism 4 is fixedly connected to a telescopic spring 6, the outside of the telescopic spring 6 is fixedly connected to the inflation mechanism 5, and the bottom end of the clamping mechanism 3 is provided with a transmission mechanism 7.
[0036] Specifically, through the movable rotation of the rotating sleeve 403 on the rotating shaft 402 and the elastic expansion and contraction between the inflatable airbag 501 and the telescopic spring 6, the inflatable airbag 501 can be movably fitted to the part to be hemostatic, thereby increasing the fitting area with the hemostatic part and preventing the connecting plate 401 from pinching the skin.
[0037] As can be seen from the above, after the rotating sleeve 403 rotates outside the rotating shaft 402, the pressure plate 404 can be moved, so that the pressure plate 404 can clamp the limbs and torso. If the torso is thin and the clamping force is small, the inflation tube 503 can be inserted into the sealing connection port 502 to fix the inflation tube 503 and the inflatable airbag 501. Then, through the piston movement of the syringe 504, the interior of the inflatable airbag 501 can be inflated, so that the inflatable airbag 501 provides greater pressure to the part to be hemostatic after inflation, so that the device can clamp and stop bleeding on different parts of the torso, thereby improving the hemostasis efficiency.
[0038] refer to Figure 2 and Figure 6 As shown, the clamping mechanism 3 includes a mounting plate 301, a first rotating rod 302 and a hinge rod 303. The outside of the mounting plate 301 is rotatably connected to the first rotating rod 302, the outside of the first rotating rod 302 is connected to the hinge rod 303, the outside of the hinge rod 303 is hinged to the second rotating rod 304, and one side of the hinge rod 303 is fixedly connected to the outside of the clamping plate 305. The first rotating rod 302, the hinge rod 303, the second rotating rod 304 and the clamping plate 305 are symmetrically arranged in two groups on the outside of the mounting plate 301. The first rotating rod 302 and the second rotating rod 304 are both rotatably connected on the outside of the mounting plate 301, and the second rotating rod 304 and the first rotating rod 302 are both rotatably connected on the outside of the hinge rod 303. The clamping plate 305 is fixedly connected to the outer wall of the connecting plate 401.
[0039] Specifically, when the rotating tooth 701 rotates, it drives the second meshing tooth 703 and the first meshing tooth 702 to rotate, so that the first rotating rod 302 fixedly connected to its surface rotates, thereby controlling the first rotating rod 302 and the hinge rod 303 to be hinged and rotated outside the mounting plate 301, thereby realizing the inward clamping control of the clamping plate 305.
[0040] Example 2:
[0041] refer to Figures 1-6As shown, the inflation mechanism 5 includes an inflatable airbag 501, a sealed connection port 502 and an inflation tube 503.

The inflation tube 503 is a transparent rubber hose. The inflation tube 503 is sealed and plugged into the sealed connection port 502. The transmission mechanism 7 includes a rotating tooth 701, a first meshing tooth 702 and a first meshing tooth 703. Two meshing teeth 703, the rotating tooth 701 is fixedly connected to the bottom end of the rotating handle 2, the outside of the rotating tooth 701 is meshed with the first meshing tooth 702, and the outside of the first meshing tooth 702 is meshed with the second meshing tooth 703. The rotating tooth 701, the first meshing tooth 702 and the second meshing tooth 703 are all rotatably connected at the bottom end of the mounting plate 301, and the outsides of the first meshing tooth 702 and the second meshing tooth 703 are both fixedly connected to two groups of symmetrically arranged first rotating rods 302.
[0042] Specifically, a one-way valve is provided on the outside of the inflation tube 503, so that the syringe 504 can inflate the inside of the inflation bag 501 when performing piston movement, thereby providing greater pressure on the hemostasis site.
[0043] As can be seen from the above, when quickly stopping bleeding on injured limbs, the movable mechanism 4 is first placed on the torso part to be stopped, and then the rotating handle 2 is rotated to enable the rotating teeth 701 to be meshed with the first meshing teeth 702, so that the first meshing teeth 702 and the second meshing teeth 703 can be rotated synchronously, so that after the first rotating rod 302 is rotated, it is hinged and rotated between the hinge rod 303 and the second rotating rod 304, realizing the inward movement of the clamping plate 305, which can quickly clamp the patient's torso, and the clamping force can be adjusted, thereby improving the efficiency of stopping bleeding and providing a stable clamping force.
