Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention.

[0025] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0026] Example

[0027] like Figure 1 As shown, the disposable load-bearing multifunctional hemostat proposed by the present invention comprises a syringe 1, and the two ends of the syringe 1 are respectively threadedly sealed with a protective upper cover 5 and a protective lower cover 4, and the protective lower cover 4 is located at one end of the syringe 1 for installing the needle. The threaded sealing connection provides a reliable seal to prevent dust, bacteria, etc. from entering the interior of the syringe, ensuring the hygiene and safety of the disposable load-bearing multifunctional hemostat during transportation and storage. When in use, unscrew the protective lower cover 4 to install the injection needle.

[0028] Furthermore, an injection rod 2 is slidably installed in the syringe 1. The syringe 1 is set with different volumes of 5-10 (mL) according to the hemostasis demand. The injection rod 2 is hollow inside and has different volumes of 5-10 (mL) according to the different specifications of the syringe 1. The same design has different volumes of 5-10 (mL). The injection rod 2 is hollow inside and is equipped with an injection inner rod 3. The syringe 1 is used to pre-load different amounts of hemostatic materials 13. The injection rod 2 is pre-loaded with different amounts of liquid that can dissolve and transport the hemostatic material 13. One end of the injection inner rod 3 extends to the outside of the injection rod 2 and is fixedly installed with a release knob 6. The release knob 6 has anti-slip grooves on its arc surface, which increases the friction on the surface of the release knob 6, making it easier for the user to turn the release knob 6 when operating it, and it is not easy to slip. One end of the injection rod 2 is fixedly connected with a rubber plug 9, and an annular groove is provided on the arc surface of the rubber plug 9, so that the rubber plug 9 can better fit with the inner wall of the injection barrel 1, effectively preventing the leakage of the liquid medicine. The annular groove and the inner wall of the injection barrel 1 form a certain interlocking structure, which increases the friction force and prevents the rubber plug 9 from shaking or being accidentally pushed out in the injection barrel 1. A rubber plug through hole 10 is provided on the rubber plug 9, and an injection rod cover 7 is threadedly installed on one end of the injection rod 2 near the release knob 6.

[0029] like Figures 2 to 3 As shown, in addition, an opening is provided at one end of the injection inner rod 3, and a limiting protrusion 14 for blocking the opening is provided at one end of the injection inner rod 2 close to the rubber plug 9, and a limiting protrusion 11 is provided at the other end of the injection inner rod 3 to limit the axial movement range of the injection inner rod 3 in the injection rod 2, and to play a precise stopping effect when the release knob 6 is operated, to ensure the normal operation process of the device and the smooth flow of liquid, to protect other components inside the injection barrel 1, and to avoid the injection inner rod 3 from being damaged by impact due to excessive movement. The cross-sectional area of ​​the limiting protrusion 14 is larger than the cross-sectional area of ​​the opening on the injection rod 2. It is convenient to better seal the rubber plug through hole 10, and the rubber plug through hole 10 can be opened or closed when needed. A leakage groove 8 is provided at one end of the injection inner rod 3 close to the rubber plug through hole 10, which facilitates the smooth flow of liquid in the injection rod 2 to the injection barrel 1, and ensures that the hemostatic material and the liquid are fused in time.

[0030] The inner wall of the end of the injection rod 2 away from the rubber plug 9 is threadedly connected with the injection inner rod 3, and the second limiting protrusion 11 is provided with an external thread, and the end of the injection rod 2 away from the rubber plug 9 is provided with a thread groove 12 adapted to the external thread on the second limiting protrusion 11. When the release knob 6 is rotated counterclockwise until it cannot be moved, the injection inner rod 3 and the leakage groove 8 are away from the rubber plug through hole 10, and the liquid that can dissolve and transport hemostatic materials in the injection rod 2 will flow along the rubber plug through hole 10 to the injection barrel 1, and the hemostatic material and the liquid that can dissolve and transport hemostatic materials in the injection rod 2 are integrated into one. When the release knob 6 is rotated clockwise until it cannot be moved, the injection needle is inserted into the position where hemostasis is required, and the release knob 6 is pressed to drive the injection rod 2 to slide in the injection barrel 1 through the injection inner rod 3 to push out the dissolved hemostatic material, and injection hemostasis can be completed. The injection rod 2 is filled with a liquid that can dissolve and transport hemostatic materials 13, and the liquid is sterile water for injection or saline injection.

[0031] Working principle: when in use, unscrew the protective lower cover 4 and install the injection needle, unscrew the protective upper cover 5, and rotate the release knob 6 counterclockwise until it cannot be moved. At this time, the injection inner rod 3 and the leakage groove 8 are away from the rubber plug through hole 10, and the liquid that can dissolve and transport hemostatic materials inside the injection rod 2 will flow through the leakage groove 8 along the rubber plug through hole 10 to the injection barrel 1. The hemostatic material and the liquid that can dissolve and transport hemostatic materials inside the injection rod 2 are integrated into one. When the release knob 6 is rotated clockwise until it cannot be moved, the injection needle is inserted into the position where hemostasis is required, and the release knob 6 is pressed to drive the injection rod 2 to slide in the injection barrel 1 through the injection inner rod 3 to push out the dissolved hemostatic material, and injection hemostasis can be completed. The device integrates hemostatic material, physiological saline and hemostatic needle body into one design, does not require time-consuming assembly, and greatly improves the efficiency of use. Especially in scenarios with high time requirements such as emergency hemostasis, it can be put into use quickly to gain precious treatment time;

[0032] According to the different requirements of carrying hemostatic materials, hemostatic needle bodies with different amounts can be designed. Hemostatic materials and physiological saline can be pre-assembled in different amounts in the hemostatic needle bodies. Such a design can accurately meet the specific needs of various actual use scenarios, ensuring that the amount of each component is suitable each time it is used, which is conducive to achieving the best hemostatic effect.

[0033] Since the hemostatic material and the injection needle are designed and assembled together according to different demand quantities, they can be completely used up each time, fundamentally avoiding the cost waste caused by surplus materials. This is more reasonable at the economic level and also helps to rationally utilize resources.

[0034] The above specific embodiments are only several optional embodiments of the present invention. Based on the technical solutions of the present invention and the relevant inspirations of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
