Target medicine ion introducing apparatus

Abstract

An ion-introduction instrument for target medicine is composed of high-voltage DC power supply, NPN-type switching transistor, trigger pulse generator, low-voltage DC power supply, two output electrodes, PNP-type short-circuit transistor, delay pulse generator and short-circuit pulse generator.

Description

technical field [0001] The invention relates to an instrument for introducing drug ions into human body for treatment, a targeted drug ion introduction instrument. Background technique [0002] Using the current generated by the iontophoresis instrument to introduce drug ions into the human body is a disease treatment method under development, and the amount of drug introduced is related to the size of the imported current. When direct current is used for drug introduction, due to the high capacitive resistance of the human skin stratum corneum, polarization will occur, and direct current is difficult to pass through, the import current is very small, and the voltage must be limited to a very low level, so as not to cause harm to the human body, and the import effect is not good. ideal. In recent years, people have proposed the method of using half-wave or unidirectional pulse current for drug iontophoresis, the purpose of which is to provide greater power for ions by gener...

Problems solved by technology

However, this structure does not provide enough time for the self-discharge of the stratum corneum of the skin at the trailing edge of each positive pulse, and the transdermal process of drug ions is not sufficient.
