[0017] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0018] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.

[0019] The rapid hemostasis injection device of the present invention is implemented as follows Figure 1 , Figure 2 As shown, the device comprises a material storage tube 1 , a push rod 2 , a tube cap 4 and a push plate 3 placed inside the material storage tube 1 .

[0020] Figure 3It is a schematic diagram of a material storage tube 1. An annular groove 13 is provided at the mouth of the material storage tube 1 to facilitate fixing the tube cap 4. A guide hole 12 is provided at the center of the bottom of the material storage tube 1. In addition, a handle 11 is preferably provided at the bottom of the material storage tube 1. The handle 11 can adopt a wing-shaped structure, which is ergonomic and easy to operate.

[0021] Figure 4 Schematic diagram of a push rod 2, which includes a handle 21 and a guide rod 22. A positioning groove 23 is provided at the front end of the guide rod 22; the handle 21 may also adopt a wing-shaped structure.

[0022] Figure 5 is a schematic diagram of the push plate 3, Figure 6 The push plate 3 is an exploded view. The push plate 3 is placed inside the material storage tube 1 and mainly includes a base 31, two sliders 32 and an O-ring 33. The base 31 is provided with a slide groove 311 and an annular groove 312, and a through hole 313 is provided at the center. The two sliders 32 are embedded in the slide groove 311 and can slide along the slide groove 311. The O-ring 33 is installed in the annular groove 312 to provide a centripetal tightening force for the slider 32. The guide rod 22 passes through the guide hole 12 of the material storage tube 1 and the through hole 313 of the push plate 3 and can slide back and forth inside the material storage tube 1. In addition, the slider 32 is provided with an arc surface 321 and a mounting hole 322. The arc surface 32 The diameter of 1 is equal to the outer diameter of the positioning groove 23, and can be inserted into the positioning groove 23, so that the push rod 2 and the push plate 3 have no axial movement relative to each other. The mounting hole 322 is mainly used for the installation of the push plate 3. When the push plate 3 is installed on the push rod 2, when the slider 32 is inserted into the positioning groove 23, a circlip pliers can be used to insert into the mounting hole 322 to open the two sliders 32 tightened by the O-ring 33, so that the arc surface 321 is separated from the positioning groove 23, so that the push plate 3 and the push rod 2 can move axially relative to each other; the base 31 has a certain thickness, and its outer diameter and the inner diameter of the storage tube 1 are installed with a small gap, which can prevent the push block 3 from turning over in the storage tube 1.

[0023] Figure 7 is a schematic diagram of the tube cap 4, which is installed at the mouth of the storage tube 1, and is provided with an annular boss 41 inside and a cutout 42 outside; the tube cap 4 is fixed by the annular boss 41 and the annular groove 13 on the storage tube 1; the cutout 42 can be a cross shape, and at the same time, the depth of the cutout 42 preferably does not penetrate the wall thickness of the tube cap 4, and a wall thickness of 0.2-0.5mm can be retained. This can not only ensure that the hemostatic material will not fall off through the tube cap 4, but also play a role in sealing and moisture-proofing. When the hemostatic material is pushed outward, the retained wall thickness can be torn open under the action of the thrust, and the hemostatic material can be pushed out of the storage tube 1.

[0024] All parts of the rapid hemostasis injection device of the present invention can be made of medical plastic materials to prevent rust, failure, pollution, etc. At the same time, the storage tube 1 is preferably made of transparent material to facilitate viewing of the drug storage volume in the device, and the tube cap 4 can be made of soft plastic material for easy installation. In addition, the injection device of the present invention is all made of plastic molds, which is easy to produce, light in weight, and convenient to transport and carry.

[0025] The quick hemostatic injection device of the present invention can be filled and used in the following manner: 1. Insert the push rod 2 into the guide hole 12 at the rear end of the storage tube 1 and push it to the end. 2. Use a circlip pliers to insert the mounting hole 322 to open the slider 32, and at the same time insert the through hole 313 on the push plate 3 into the guide rod 22. While keeping the position of the push rod 2 unchanged, push the push plate 3 to the rear of the positioning groove 23. 3. Use a tool to push the push plate 3 to the bottom end of the storage tube 1. 4. Fill the solid hemostatic material from the mouth of the storage tube 1 until the storage tube 1 is filled. 5. Put on the tube cap 4 and the filling is complete. 6. When in use, the push rod 2 can be pulled out of the storage tube 1, so that the slider 32 on the push plate 3 and the positioning groove 23 set on the guide rod 22 are engaged, so that the push plate 3 and the push rod 2 do not produce axial relative displacement. 7. Push the push rod 2 into the storage tube 1 to drive the push plate 3 to squeeze the hemostatic material toward the tube opening of the storage tube 1. Under the action of pressure, the cross cut 42 on the tube cap 4 is squeezed open and injected into the wound.

[0026] The rapid hemostasis injection device of the present invention has a simple structure and is convenient and quick to manufacture, install and use. It can safely, quickly and conveniently push various solid hemostatic materials to the hemostasis site to achieve the effect of rapid hemostasis.
