Description

Soluble microneedle patch convenient to press

Technical Field

The utility model relates to a soluble micropin paster of conveniently pressing.

Background

In recent years, microneedle patches have received unprecedented heat in the cosmetic field and have been widely used in europe, the united states of america, japan, korea, china, and the like. The product has wide application in the field of beauty treatment, and can be used for body shaping and skin beautifying. The microneedles on the microneedle patch can pierce the skin to form microchannels in the stratum corneum, so that the cosmetic active ingredients reach the deep layer of the epidermis along the microchannels and diffuse into the dermis. The soluble micro-needle prepared by taking hyaluronic acid as a substrate can not only play a role of beautifying, but also can not cause inflammatory reaction because hyaluronic acid is a human endogenous substance because hyaluronic acid is dissolved and retained in skin under the action of body fluid after the hyaluronic acid penetrates into the skin of a human body.

There are a variety of soluble microneedle patches available, such as the soluble microneedle patch disclosed in document CN209316551U, including: a dissolvable substrate and a dissolvable microneedle array, and a viscous mixture having solubility and/or biodegradability for adhering the dissolvable microneedle patch to a skin surface; also disclosed in document CN103893018B is a soluble hyaluronic acid microneedle patch consisting of a microneedle array and a substrate; for another example, the painless soluble vaccine microneedle patch disclosed in document CN209154573U includes a protective layer, a soluble microneedle body and a soluble microneedle substrate, the soluble microneedle body is composed of a needle head, a needle rod and a needle platform, and is distributed on the soluble microneedle substrate in an array, the front end of the needle head is provided with an inclined plane, the target drug is loaded on nanoparticles uniformly distributed on the needle head, the needle rod is designed in a ladder shape with a narrow top and a wide bottom, the bottom of the needle rod is connected with the needle platform, and the bottom of the needle platform is compounded on the soluble microneedle substrate. As described above, the soluble microneedle patches each include a sheet-shaped base and soluble microneedles disposed on the base, and when the patch is used, the soluble microneedles are inserted into the skin by lightly pressing the patch base with fingers. Because the substrate of the soluble microneedle patch is very thin and has toughness, and the part of the human body to be subjected to the needle is not flat, when the soluble microneedle patch is large, the non-pressed part is always easy to tilt up, so that the needle is very inconvenient to press and insert. In this regard, the current solution is mainly to make the soluble microneedle patch smaller, however, this increases the number of the soluble microneedle patch used, for example, 2-4 patches are usually needed for the cheek area of the face, and 3-4 patches are also needed for the back of the hand, which is cumbersome to use.
