Implantable drug-supplying device of check valve seal-free pipe

Abstract

The invention discloses an implantable drug-supplying device of a check valve seal-free pipe. The implantable drug-supplying device comprises a drug-supplying device body, wherein the drug-supplying device body is connected with a guide pipe through a locking device and comprises a pump seat, the upper end of the pump seat is provided with a puncture diaphragm, and the upper end of the puncture diaphragm is provided with a pump cover; the pump cover, the puncture diaphragm and the pump seat are hermetically connected, the pump seat is connected with a check valve, and a pump cavity is formed among the pump cover, the puncture diaphragm, the pump seat and the check valve. The implantable drug-supplying device provided by the invention has the beneficial effects that a medicine in an artery pump can directly enter a set part to realize targeted therapy, therefore the curative effect that the killability of pathological cells can be improved by about four times when 1 point of the concentration of the medicines on a focus par is improved; furthermore, the medicine can be effectively prevented from refluxing to block the guide pipe, therefore the operation of needing a heparin sealing water pipe can be prevented after the medicine is injected by the patient by medical personnel, and the practiclaity of the device can be effectively improved.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a non-sealing tube implantable drug delivery device with a one-way valve. Background technique [0002] At present, all kinds of catheters that enter the human body on the market need to stay in the human body for more than a week. Medical personnel need to use heparin water to seal the catheter after injecting drugs with the catheter. The water outlet at the front end of these catheters is often blocked by thrombus and cannot be used any longer. This situation is easy to be mistaken for the infection of patient's wound, and above-mentioned situation has brought loaded down with trivial details work to medical staff, makes the people feel that this type of apparatus is used too troublesome. [0003] Aiming at the problems in the above-mentioned related technologies, no effective solution has been proposed yet. Contents of the invention [0004] In view of the above-mentioned pr...
