Abstract
An apparatus for transdermal fluid delivery includes a handle and a tip, having a skin applying surface, being driven to move by a driving unit. A fluid delivery structure has an aperture formed at the skin applying surface and a vacuum entry port. An abrading structure, an electrode structure, and a micro-needling structure are selectively provided at the skin applying surface with the fluid delivery structure to provide multiple functions of the tip. A flow of fluid is delivered onto the skin applying surface through the fluid delivery structure to interact with the abrading elements and the electrodes before the fluid is returned and collected, so that three different skin treatments of abrasive peeling, electrical stimulation, and liquid infusion are achieved in one single structure for improving a skin structure.
