The technical scheme adopted by the invention is as follows: a microneedle accessory device comprises a liquid medicine bag containing liquid medicine, wherein the liquid medicine bag is in a sheet shape, one surface of the liquid medicine bag facing a human body is taken as a front surface, a micro-pressure bag is bound on the back surface of the liquid medicine bag through a binding piece, a plurality of hollow microneedles are arranged on the front surface of the liquid medicine bag, and the hollow microneedles are communicated with the liquid medicine in the liquid medicine bag; the shape of the micro-pressure bag is matched with the liquid medicine bag, the micro-pressure bag is an expandable air bag and is connected with a pressurized air source through an air conveying pipe, and the liquid medicine bag is provided with an adhesive part which is adhered to the skin of a patient.
Furthermore, a plurality of sac cavities are separated in the air bag, and each sac cavity is connected to a pressurized air source through an air conveying pipe.
Further, the pressurized air source is a pressurized kneading ball or a micro-pressure air pump.
Further, the hollow microneedles are arranged in an array structure, and the array structure is a rectangular array structure, a circular array structure or a linear array structure.
Furthermore, the liquid medicine bag is made of medical silica gel materials, and the micro-pressure bag is made of elastic materials.
Further, the hollow microneedle has a length of 2 mm.
The invention has the beneficial effects that: the microneedle accessory device can be attached to the surface of the skin in a mode like an external accessory, and the drug is injected into the dermis through micro-pressurization, so that the treatment area is large, the efficiency is high, the cost is low, and the drug is more efficient in treatment of the skin and convenient for people.
