Problems solved by technology
In clinical practice, implantable drug delivery pumps are often used as drug delivery devices for continuous drug delivery, but implantable drug delivery pumps are expensive and risky, and patients will be more cautious in choosing them, which affects timely treatment of patients
In actual treatment, the infusion port can also be connected to an external analgesic pump as a drug delivery device. The cost and risk of the infusion port are lower than that of implanted drug delivery pumps, but it will restrict the patient's movement and affect the quality of life

The invention relates to the technical field of infusion ports, in particular to an infusion port drug delivery device and a method for treating chronic pain through the infusion port drug delivery device. The metal connecting pipe is fixed on the injection seat, and the conduit is arranged outside the metal connecting pipe; the outer portion of the guide pipe is pressed and sealed through a pressing cap. The pressing cap comprises a fixed seat, a through hole and a shell; a through hole is formed in the shell, and a fixed seat is arranged at the front end of the shell; a guide pipe is fixed in the through hole; and the shell and the fixed seat are integrally formed. The connecting structure has the beneficial effects that the metal connecting pipe is sleeved with the guide pipe, then the pressing cap is sleeved to ensure the sealing of the connecting part, and the pressing cap and the connecting pipe are clamped to form firm connection; the structure and operation are simple; meanwhile, the infusion port and the implantable dosing pump are connected with the catheter in the same connection mode, so that the dosing mode can be conveniently replaced according to the will of the patient, secondary puncture is avoided, and the pain of the patient is reduced.
Description
technical field [0001] The invention relates to the technical field of infusion port drug delivery devices, in particular to an infusion port drug delivery device and a method for treating chronic pain. Background technique [0002] The infusion port is a fully implanted closed infusion system embedded in the human body. The system consists of a catheter that is connected to a device called an injector at the end of the catheter. The administration end of the catheter is placed in the target area by subcutaneous puncture, and the other end of the catheter is connected to the injection seat. The injection seat is placed in the subcutaneous tissue near the cavity and fixed by suturing. After the operation, only a small suture wound can be seen on the skin. After the stitches are removed, a protruding ball can be felt on the patient's body surface. During the treatment, the needle is positioned from this position, and the needle is punctured vertically into the liquid storage...
