[0002] In the medical field, high-pressure medical catheters play a crucial role in high-pressure fluid transfer scenarios such as high-pressure injections and hemodialysis. However, traditional high-pressure medical catheters have certain limitations when dealing with high-pressure environments. On the one hand, when subjected to high pressure, the outer wall of the catheter is prone to localized deformation due to pressure. Long-term use may lead to problems such as catheter rupture and leakage, which not only affects the normal conduct of medical procedures but may also pose potential risks to patients. On the other hand, during complex medical procedures, catheters may be subjected to various external forces of stretching and bending. Ordinary connection methods and structures cannot guarantee that the catheter will maintain a stable connection and good pressure resistance under these conditions. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] This utility model provides, for example Figure 1-5 The illustrated medical high-pressure connecting catheter includes a high-pressure connecting catheter body 2 and a female connector 1 inserted into the left end of the high-pressure connecting catheter body 2. A male connector 4 is inserted into the right end of the high-pressure connecting catheter body 2. The female connector 1 is composed of a connecting reinforcing ring 5, an external sleeve 6, and a connecting catheter plug A7. The connecting catheter plug A7 is inserted into the left end of the high-pressure connecting catheter body 2. The left end of the connecting catheter plug A7 is connected to the external sleeve 6, which is located on the left side of the high-pressure connecting catheter body 2. A connecting reinforcing ring 5 is provided on the circular outer wall of the left end of the external sleeve 6. The external sleeve 6 is connected via a connecting... The catheter plug A7 is internally connected to the high-pressure connecting catheter body 2. The high-pressure connecting catheter body 2 is made of medical-grade polyvinyl chloride. Both the inner and outer walls of the high-pressure connecting catheter body 2 are smooth and burr-free. The high-pressure connecting catheter body 2 can be bent at large angles in any direction. The medical-grade polyvinyl chloride material has good biocompatibility, which can ensure safe use in the medical environment. Its smooth and burr-free inner and outer walls not only reduce the resistance to the transmitted liquid and ensure smooth liquid transmission, but also allow the catheter to be bent at large angles in any direction, adapting to various complex medical operation scenarios and improving the flexibility and convenience of catheter use.

[0023] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the male connector 4 is composed of a connecting conduit plug B8, a reinforcing and encrypted rubber ring 9, a hollow pressure-relieving head 10, and a connecting outer tube plug 11. The hollow pressure-relieving head 10 has a connecting conduit plug B8 at its left end and a connecting outer tube plug 11 at its right end. The connecting conduit plug B8 is inserted into the right end of the high-pressure connecting conduit body 2. Multiple recessed rubber ring slots are equidistantly arranged on the circular outer walls of the connecting conduit plug B8, connecting conduit plug A7, and connecting outer tube plug 11. Reinforcing and encrypted rubber rings 9 are fitted into each of these slots, and the circular outer wall of the reinforcing and encrypted rubber ring 9 protrudes beyond the outer walls of the connecting conduit plug B8, connecting conduit plug A7, and connecting outer tube plug 11. After the connecting conduit plug A7 and connecting conduit plug B8 are respectively inserted into the two ends of the high-pressure connecting conduit body 2, the connecting conduit plug A7 and connecting conduit plug B8 are connected by a reinforcing and encrypted rubber ring 9. The reinforced rubber ring 9 is press-fitted with the high-pressure connecting catheter body 2. In terms of connection structure, the design of the connecting female head 1 and the connecting male head 4 ensures reliable connection of the catheter with other medical devices. The connecting catheter plug A7 of the connecting female head 1 is inserted into the left end of the high-pressure connecting catheter body 2. The external sleeve 6 and the connecting reinforcing ring 5 enhance the stability and sealing of the connection. The connecting catheter plug B8 of the connecting male head 4 is inserted into the right end of the high-pressure connecting catheter body 2. Together with the connecting female head 1, it ensures the stability of the entire connection system. The reinforced rubber ring 9 is a key component to ensure the sealing of the connection. The rubber ring groove on the circular outer wall of the connecting catheter plugs A7 and B and the connecting outer tube plug 11 is press-fitted with the reinforced rubber ring 9. This design not only ensures a tight connection and prevents liquid leakage, but also effectively resists high-pressure environments and ensures the reliability of the connection during high-pressure liquid transmission.

[0024] like Figure 1 and Figure 5 As shown, a high-pressure reinforcement device 3 is provided on the outside of the high-pressure connecting conduit body 2. The high-pressure reinforcement device 3 includes annular reinforcement rings 12, rope holes 13, connecting fixing pieces 14, and reinforcing nylon wires 15. Multiple annular reinforcement rings 12 are provided, and multiple annular reinforcement rings 12 are equidistantly sleeved and fixed on the outside of the high-pressure connecting conduit body 2, forming multiple reinforcement lines. These annular reinforcement rings 12 are connected to each other by equidistantly distributed connecting fixing pieces 14 to build a stable overall frame. This frame structure can evenly disperse the outward expansion force generated by the high pressure inside the conduit, avoiding excessive local pressure that could cause the conduit to deform. Multiple annular reinforcement rings 12 are equidistantly connected to each other by multiple connecting fixing pieces 14. Multiple rope holes 13 are equidistantly arranged inside the annulus of multiple annular reinforcement rings 12, and each rope hole 13 is provided with a reinforcing nylon wire 15.

[0025] like Figure 1 and Figure 5As shown, the reinforcing nylon thread 15 is connected end to end in the rope hole 13. The reinforcing nylon thread 15 is like a tight net, further binding the annular reinforcing ring 12 and the catheter body. When the internal pressure of the catheter increases, the reinforcing nylon thread 15 can withstand some tension, preventing the annular reinforcing ring 12 from shifting or deforming due to pressure, thereby enhancing the overall reinforcement effect of the device on the catheter. The thickness of the annular reinforcing ring 12 is less than the thickness of the high-pressure connecting catheter body 2. Both the annular reinforcing ring 12 and the connecting fixing piece 14 are made of medical-grade polyurethane. Medical-grade polyurethane material has good flexibility and strength, which can not only fit tightly against the outer wall of the catheter, but also provide sufficient pressure resistance for the catheter while ensuring that the bending performance of the catheter is not affected. The annular reinforcing ring 12 and the connecting fixing piece 14 have the same thickness. Multiple connecting fixing pieces 14 are attached and fixed to the outer wall of the high-pressure connecting catheter body 2. The equal thickness ensures that the pressure resistance of the catheter is effectively improved without increasing the volume and weight too much, ensuring the safe and stable use of the catheter in a high-pressure environment.

[0026] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
