Abstract

The invention discloses an implantable electrode having a drug release function. The implantable electrode automatically releases a drug during body monitoring. The implantable electrode having the drug release function includes a sensing body and a drug release chamber. After the electrode is implanted into the human body, a substance to be monitored reacts in a sensing chamber of the sensing body to generate a monitoring signal; and the drug is automatically released into the body through the drug release chamber. On the one hand, the implantable electrode can automatically release the drugwithout affecting the accuracy of the continuous monitoring; and on the other hand, the drug can be subjected to personalized supplementation, and the implantable electrode has the advantages of beingconvenient to operate, suiting the remedy to the case and having a long monitoring life.

Description

[0001] 【Technical field】 [0002] The patent of the present invention relates to the technical field of medical monitoring equipment, in particular to a subcutaneous implantable electrode. [0003] 【Background technique】 [0004] Existing implantable electrodes are mostly used for continuous monitoring of human physiological information, taking continuous blood glucose monitoring sensors as an example. The biggest limiting factor in sensor lifetime is the working electrode. At present, most of the existing continuous blood glucose monitoring products are imported. One sensor electrode can only monitor for about 7 days, and long-term monitoring cannot be realized. Repeated replacement of electrodes will bring the risk of infection and heavy economic burden to patients. Moreover, the existing electrode with drug release function is to cover the surface of the electrode with drugs, and after being implanted into the human body, it diffuses into the human body to play an anti-infl...
