Infusion port capable of preventing pipe from falling off and turning over

The invention relates to an anti-falling and anti-overturning infusion port and belongs to the field of medical instruments. The anti-falling and anti-overturning infusion port is composed of a puncture partition, a base, a side wall, an anti-falling connector, a liquid storage pool and a catheter. The side wall and the base are made of one of metal and polysulfone, a developing ring is arranged at the joint of the side wall and the puncture septum, the base is provided with suture holes and a microscopic porous structure, on one hand, the base can be fixed through suture lines in the earlier stage, acting force between the base and tissue is increased, and on the other hand, the microscopic porous structure can be used for cell ingrowth in the later stage; the contact area and friction force are increased to reduce the reversal risk of the port. The anti-falling interface axially and radially fixes the catheter and the connecting needle tube through the male joint, the female joint and the pressurizing butto
