Abstract

The invention discloses an ultrasound drug assisted treatment device. The device comprises an ultrasound excitation pulse generation circuit, an electroporation pulse generation circuit, an electricalstimulation signal generation circuit and a single chip microcomputer; an ultrasound excitation pulse, an electroporation pulse and an electrical stimulation signal are integrated into a whole and selected through the single chip microcomputer for cooperative use as needed. The permeation effect of drug use is improved, the local part or the whole body of a human body is better treated, the circuit is ingenious, implementation is easy, and the device has a good application prospect.

Description

technical field [0001] The invention relates to the technical field of drug therapy assistance, in particular to an ultrasonic drug-assisted therapy device. Background technique [0002] Human skin is composed of epidermis, dermis and subcutaneous tissue. Subcutaneous tissue is a kind of adipose tissue, which does not affect the transdermal absorption of drugs. The epidermis is divided into base layer, spinous layer, granular layer, transparent layer and stratum corneum. The brick wall structure of the stratum corneum determines that the stratum corneum is the transdermal absorption of drugs. The main barrier and in which lipids play a major role. The hydration of human skin can increase the permeability of non-polar fat-soluble molecules, but has little effect on the permeability of polar molecules. [0003] At present, the permeability of the skin can be improved through physical methods in order to increase the absorption effect of drugs, including the following three m...
