[0022] Embodiment 1
[0023] Referring to Figures 1 to 4The utility model discloses an anti -disengagement venous transfusion port, including transfusion port body 1 and telescopic component 2 and fixed component 3, it is characterized in that: telescopic component 2 includes the first connecting port 21 of fixed connection in transfusion port body 1 interface, the telescopic pipe 22 of fixed connection in the side end of first connecting port 21, the second connecting port 23 of fixed connection in the outer end of telescopic pipe 22, the spring piece 24 of fixed connection in first connecting port 21 and second connecting port 23, fixed sleeve 31, connecting piece 32 being arranged in both sides of fixed sleeve 31, fixed piece 33 being arranged on connecting piece 32 are included in fixed component 3.
[0024] The diameter of the fixed sleeve 31 is greater than the diameter of the liquid inlet channel of the transfusion port body 1.
[0025] The first connecting port 21 and the second connecting port 23 are made of hard plastic material, and the spring piece 24 is made of plastic material. The telescopic pipe 22 is made of an elastic bellows.
[0026] The side end of the second connecting port 23 is fixedly connected with the catheter 11.

[0030] Embodiment 2
[0031] Operation principle of the utility model:
[0032] After implanting the transfusion port into the patient's body, when the limb near the patient's transfusion port moves, the telescopic pipe 22 or the spring piece 24 between the transfusion port body 1 and the catheter 11 will be stretched or compressed. The purpose of this design is to provide flexibility and elasticity between the transfusion port and the catheter, to reduce stress concentration and displacement at the connection between the transfusion port and the catheter, thereby improving the stability and safety of the connection.
[0033] The telescopic pipe 22 itself has elasticity, mainly responsible for stretching and compression when the patient moves, thereby reducing the pressure and stress at the connection between the transfusion port and the catheter. The spring piece 24 plays an auxiliary role, providing additional elastic support, enhancing the restoring force and stability of the telescopic pipe, so that the overall structure can recover faster when subjected to external force. This double-elasticity structure helps to improve the durability and safety of the device, further reducing the risk of catheter breakage or falling off.
[0034] The port body 1, the telescopic assembly 2 and the catheter 11 are in the patient's body, and the port body 1 forms a protrusion on the skin surface. In order to stabilize the port body 1, the fixing sleeve 31 is sleeved on the protrusion on the skin, and the fixing member 33 is pasted on the skin, so that the fixing member 33 stabilizes the fixing assembly 3 in the appropriate position, thereby preventing the port body 1 from moving or shifting. In addition, after the fixing assembly 3 is used for a period of time, the old fixing member 33 can be removed from the connecting member 32 and replaced with a new fixing member 33, and such a design enables the fixing sleeve 31 to be used for a long time to maintain stability and comfort.
