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.

Dependent claims

An apparatus for transdermal fluid delivery, comprising a multi-functional tip having a skin-applying surface, a support member within a handle structure, comprising a fluid delivery structure, and a tip driver,

wherein said support member comprises a driving unit and a driving shaft operatively extended from said driving unit to said multi-functional tip, wherein said driving shaft has at least a hollow portion extended to said multi-functional tip, wherein said driving unit is operated to generate a movement by a motor at said skin applying surface of said multi-functional tip;
wherein said support member comprises a fluid delivery channel defined at said hollow portion of said driving shaft and at least an aperture formed at said skin applying surface of said multi-functional tip to communicate with said fluid channel, so that said driving shaft drives said skin applying surface of said multi-functional tip to move and also guides a flow of fluid through said fluid channel to said skin applying surface of said multi-functional tip at said aperture at the same time,
Wherein said support member provides a driving unit within a driving shaft to perform a dual function to allow a fluid to flow through said driving unit while said driving unit is simultaneously moved by a motor.

An apparatus for transdermal fluid delivery, comprising a handle, a multi-functional tip, a support member and a fluid delivery structure,

wherein said handle has a working end;
wherein said multi-functional tip, having a skin applying surface located at said working end of said handle, comprises a plurality of abrading elements attached to a support member within said handle provided at said skin applying surface with an electrode module which comprises a plurality of electrodes encircled around said abrading elements of said skin applying surface;
wherein said fluid delivery structure has at least an aperture located within a plurality of abrading elements at said skin applying surface and a vacuum inlet formed at a perimeter of said electrode module, wherein a fluid traveling path is defined between said aperture and said, vacuum inlet for ensuring a flow of fluid to deliver contact onto said skin applying surface through said aperture and to interact with said abrading elements and said electrodes all before said fluid is pulled back through said vacuum inlet, so that three different functions of skin treatments such as abrasive peeling, electrical stimulation, and liquid infusion are achieved in one single structure to increase transdermal fluid delivery for improving the results of a treatment area.

A method for transdermal fluid delivery, comprising the steps of:

(a) holding a handle stationary to locate a working end of said handle on a skin surface;
(b) delivering a flow of fluid onto a skin applying surface through an inner structure of a multi-functional tip through a support member at an aperture which is formed on said skin applying surface, wherein said skin applying surface is located at said working end of said handle;
(c) evenly distributing said fluid through a plurality of rotatable and or vibration abrading elements of an inner structure of the multi functional tip attached to the driving shaft of a support member which is moved by a motor are provided onto said skin applying surface;
(d) driving said multi-functional tip to rotate and or vibrate an abrasive element to abrade the contact surface while said handle is stationary;
and
(e) simultaneously guiding said fluid through a support member to interact with a plurality of electrodes of an electrode module of an intermediate structure of the multi functional tip encircled around an inner structure of the multi functional tip of said skin applying surface.
