Abstract:
1. 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, a fluid returning structure and a tip driver; wherein said skin applying surface of said multifunctional tip comprises a plurality of abrading elements and a plurality of electrodes encircling said abrading elements; wherein said support member comprising said fluid delivery structure, said fluid returning structure and said tip driver is secured inside a casing within said handle structure; wherein said tip driver comprises, a driving unit and a driving shaft; wherein said driving shaft is operatively extended from said driving unit to said multi-functional tip through a center slot of said support member, wherein said driving shaft is movable and said support member is stationary; wherein said multifunctional tip comprising said plurality of abrading elements and said plurality of electrodes is detachably coupled at a free end of said driving shaft; wherein said driving shaft has at least a hollow portion extended to said multi-functional tip, wherein a fluid delivery channel of said fluid delivery structure is defined at said hollow portion of said driving shaft; wherein said fluid delivery structure further has a fluid inlet transversely formed at said driving shaft to guide a fluid from an interior fluid cavity of said support member into said fluid delivery channel defined at said hollow portion of said driving shaft, wherein said fluid delivery structure has at least an aperture located at an axial center of said skin applying surface of said multi-functional tip to communicate with said fluid delivery channel defined at said hollow portion of said driving shaft and deliver fluid to the skin surface; wherein said driving shaft has a dual function of driving said skin applying surface of said multi-functional tip to rotate while concomitantly guiding a flow of a fluid through said fluid delivery channel to said skin applying surface of said multi-functional tip at said aperture; wherein said driving unit is operated to generate a movement by a motor at said skin applying surface of said multi-functional tip through said driving shaft; and wherein said fluid returning structure comprises a vacuum inlet, a vacuum port and a vacuum passage, wherein said vacuum passage is extended through said support member to transport a used fluid collected by said vacuum inlet from said multifunctional tip by said vacuum port to a reservoir at a rear end of said support member.
