Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art based on the embodiments of the present invention without inventive step, are within the scope of the present invention.

As shown in fig. 1 and fig. 2, a microneedle electrode plate includes a base 3, a conductive layer 4, a drug layer 5 and a microneedle structure, wherein the conductive layer 4 is disposed at the bottom of the base 3, and the drug layer 5 is disposed between the conductive layer 4 and the microneedle structure; the micro-needle structure comprises a base layer 9, a fixing piece 6 and a hollow needle body 7, wherein the top of the base layer 9 is arranged at the bottom of the medicine layer 5, the needle body 7 is arranged at the bottom of the base layer 9 through the fixing piece 6, and the base layer 9 is provided with a through hole for communicating the needle body 7, corresponding to the needle body 7.

When the micro-needle structure is used, the micro-needle structure is aligned to an action part and is tightly pasted, the whole body is fixed at the action part by the base body 3, the inserting port 2 is used for inserting the conducting wire 1 to be connected with equipment, after the conducting layer 4 is electrified, current is generated among the conducting layer 4, conducting liquid medicine and skin, and simultaneously, the liquid medicine of the medicine layer 5 flows out of the medicine layer 5 under the action of an electric field and enters the junction of the dermis layer and the subcutaneous layer through the hollow needle body 7. The micro-needle structure which is uniformly arranged enables micro-current which is contacted with the skin to be uniformly distributed, and simultaneously, the micro-needle structure is convenient for the uniform contact of the medicine and the skin.
