Electric energy auxiliary device of transdermal drug delivery patch

摘要

An electric energy auxiliary device of transdermal drug delivery patch is provided which includes an upper electrode, a lower electrode, and a drug storage area between two electrodes, generating a kinetic energy in the pharmaceutical compound in the drug storage area toward the skin by a electric field between two electrodes. For the pharmaceutical compound with the same polarity, the pharmaceutical compound is pushed by the electric energy interacted with polar the pharmaceutical compound so as to deliver the drug the human body. The lower electrode generates an ion channel with electroporation on the surface of skin. By using the change of electric field on the surface of skin, a temporary ion channel is generated in the cells where the pharmaceutical compound enters the systemic circulation of human body via skin. This temporary ion channel allows large compound to pass into the skin of human body.
