Abstract

The invention provides a subcutaneous implantation type drug release system which comprises an external incentive and control circuit and a subcutaneous implantation chip. The external incentive and control circuit comprises a first transmission electrode and a second transmission electrode, the subcutaneous implantation chip comprises a first transmission terminal and a second transmission terminal. The first transmission terminal is in coupling connection with the first transmission electrode of the external incentive and control circuit and the second transmission terminal is in coupling connection with the second transmission electrode of the external incentive and control circuit to enable the external incentive and control circuit and the subcutaneous implantation chip to form a closed current loop. The subcutaneous implantation type drug release system has the advantages of achieving real-time targeted drug release due to the fact that human skin tissues are utilized as a signal transmission medium, playing an important role in an emergency and being capable of helping to treat chronic diseases needing for long-term repeated drug treatment at the same time.

Description

technical field [0001] The invention belongs to the field of electronic technology, in particular to a subcutaneous implanted drug release system. Background technique [0002] People are often threatened by sudden diseases and unexpected emergencies in their lives. If these sudden diseases cannot be treated quickly and immediately, it is likely to cause the deterioration of the condition and even endanger the life of the patient. The traditional injection administration method has high immediacy, but relevant medical personnel are required on site, and the requirements for disinfection and injection techniques are high. In most emergencies or accidents, injection therapy often cannot be implemented smoothly, which delays the treatment of some sudden diseases. For special groups such as soldiers and special police, the requirements for treatment timeliness in emergency situations are higher. In addition, with the advent of an aging society, chronic diseases that require lo...
