Embodiment 1
[0039] Figure 1-Figure 9 The metal microneedle array flexible patch provided by the present invention is shown, the patch includes a flexible substrate 1, and at least two are arranged at a certain distance and fixed on the surface of the flexible substrate 1 or partially embedded in the flexible substrate 1. The metal microneedle module in the flexible substrate 1, the metal microneedle module is a metal sheet 3 with protruding microneedles 2 at the edge, or a metal sheet fixed on the needle seat 4 with protruding microneedles 2 at the edge The sheet 3, or the discrete metal microneedle 2 fixed on the needle base 4, the microneedle 2 is perpendicular to the surface of the flexible substrate 1, and the tip of the microneedle 2 protrudes outward. Through the metal microneedle array flexible patch, the patch can conform to the surface of the drug application site, ensuring that the microneedles 2 can penetrate the drug application skin at the same time, and improve the effect o...
Embodiment 2
[0054] Figure 10 and Figure 9 A cross-sectional view of the structure of the transdermal drug delivery device using the metal microneedle array flexible patch provided by the present invention, the transdermal drug delivery device includes a metal microneedle array flexible patch and a base 9, and one end of the base 9 is The patch fixing surface, the other end is the handle 10 for operation, the patch fixing surface is a flat or arc-shaped curved surface, and the metal microneedle array flexible patch is permanently or detachably fixed on the patch fixing surface , or the metal microneedle array flexible patch is partially embedded in the patch fixing surface.
[0055] exist Figure 10 Among them, the metal microneedle array flexible patch is fixed on the planar patch fixing surface at one end of the base 9, and the tip structure of the microneedle 2 is different from the previous figures, specifically the tip structure with a slope.

Embodiment 3
[0060] An embodiment of the present invention provides a transdermal drug delivery patch based on the metal microneedle array flexible patch, which consists of a metal microneedle array flexible patch and a transdermal patch covering it, wherein the transdermal The patches contain one or more medicinal ingredients or beauty and skin care products with therapeutic, health care or beauty care effects. Preferably, the transdermal patch is only covered on the protruding microneedles or needle tips of the metal microneedle array flexible patch, which can not only save precious medicine, but also easily control the amount of medicine entering the skin. The grooves and holes on the microneedle can not only be used to store more drugs, but also can effectively avoid the problem of drug falling out of the body during the process of piercing the skin. A variety of common physical or chemical methods such as dipping, coating, fumigation and deposition can be used to cover the transdermal...
