MICRONEEDLE TRANSDERMAL TRANSPORT DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a transdermal transport device for accurately inserting a microneedle without any pain and programmably controlling its transport.

SOLUTION: This transdermal transport device 10 includes a reservoir for holding a formulation of an active principle, and a needle 14 with a bore extending along the full length of the needle 14 from a first end of the needle 14 to a second end of the needle 14. The second end is substantially aligned to a plane parallel to a body surface of a biological body when the device 10 is placed on the body surface. The device 10 also has an actuator 30 which pumps the formulation through the bore of the needle 14 between a target area of the biological body and the reservoir.
