Abstract

A transdermal micro -patch (1) for use with living tissue (19) is provided. The micro -patch (1) includes a first membrane (9), a reservoir (3), a micro -pump (4), flextensional transducers (2), a microelectronics circuit (5), and an optional sensor (27). The first membrane (9) is permeable to allow the passage of fluid (1 8) in either a unidirectional or bidirectional fashion. The reservoir (3) is a container -like element capable of storing a fluid (19) removed from or communicated into the tissue (19). The micro -pump (4) facilitates transport of the fluid (1 8) between the reservoir (3) and first membrane (9). The flextensional transducers (2) generate ultrasonic waves (15) which are separately communicated into the tissue (19) to transport fluid (18) between the first membrane (9) and tissue (19). Ultrasonic waves (15) could interact to enhance the performance of the micro-patch (1). The microelectronics circuit (5) controls both flextensional transducers (2) and the micro -pump (4). The sensor (27) could be embedded within the micro -patch (1) to monitor temperature, pressure, or flow rate so as to avoid damage or irritation to the tissue (19).

Description

technical field [0001] The present invention is primarily concerned with a fully functional, self-contained, needle-free fluid management system through which fluids, including medication, oxygen, nutrients, can be injected into tissues or wounds, and such fluids in the skin Fluid is aspirated. In particular, the present invention relates to a micro-transdermal patch that is easy to handle, and the patch includes a first and a second membrane, and one or more independently operable membranes disposed between the first and second membranes. A flextensional transducer, a micropump connected to a reservoir, an optional encapsulation chamber, an optional feedback sensor, and a miniature electronic circuit. Micropumps and transducers are controlled by the tiny electronic circuitry to cause fluids and the like to be injected into the skin or drawn out through the first membrane. Background technique [0002] Effective treatment of trauma, disease, and other medically related con...
