Abstract

The invention relates to a hot-compress-type micro-nano wafer mechanical integrated transdermal medicine delivery device. The device comprises a medicine tank for storing a liquid medicine, a nano wafer, a heating assembly, a driving assembly, a power supply and a controller; the nano wafer, the heating assembly and the driving assembly are all connected with the medicine tank; the heating assembly and the driving assembly are both connected with the power supply and the controller; one side, far away from the medicine tank, of the nano wafer is provided with a plurality of micro needles whichare arranged at intervals and used for piercing a skin; each micro needles is provided with a through hole communicating with the medicine tank; the heating assembly is used for heating the liquid medicine in the medicine tank; the driving assembly comprises a pulse electromagnetic coil and a permanent magnet; the permanent magnet is arranged on the medicine tank; the pulse electromagnetic coil is arranged opposite to the permanent magnet; and the pulse electromagnetic coil is connected with the power supply and the controller, wherein the power supply is used for supplying power to the heating assembly and the driving assembly, and the controller is used for controlling the heating temperature of the heating assembly and controlling the driving assembly to drive the nano wafer to reciprocate mechanically before each time of medicine delivery.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a heat-compressed micro-nano chip medicine-machine integrated transdermal drug delivery device. Background technique [0002] Nano-microneedle wafers are being widely used in the technical field of transdermal devices. Nano-microneedles are formed by processing many micro-nano pyramid structures on a single crystal silicon substrate using semiconductor technology. Usually the size of the needle tip is at the nanometer scale, so it is also called nano-micro-needles. The arrangement of these micro-needles is mainly In a rectangular array, the pitch of the microneedles is usually between 300-1000 micrometers, and the height of the microneedles is in the range of 70-300 micrometers. Take a small semiconductor square such as 4mm×4mm covered with microneedles, press this small square on the skin, the stratum corneum on the skin surface will be pierced, and then apply ointment on the ski...
