Apparatus and method for producing sheet-like material pieces

Technical Field

The invention belongs to the technical field of material production, and particularly relates to equipment and a method for preparing a sheet-shaped material part.

Background

Most therapeutic agents are delivered to the body by subcutaneous injection, which is a low cost, rapid and straightforward way of administering the drug. Patients themselves, however, do not have the ability to use syringes with greater ease, and the pain and fear associated with syringes further limit patient compliance. One of the solutions to the above problems is to load drugs on microneedles (including needles with a size of micrometer scale) and administer them transdermally. The microneedle transdermal administration mode can realize drug delivery without pain, and improve the compliance and safety of patients. Meanwhile, the micro-needle can realize quantitative and positioning delivery of medicaments and the like, can realize accurate administration and has good administration effect. In addition, microneedles can also be used as skin pretreatment, with the ability to enhance skin permeability. Therefore, the micro-needle has better clinical application prospect. However, the production of single microneedle patches has the problems of incapability of continuous mass production, low production efficiency, complex structure, incapability of recycling waste materials and the like. Of course, in addition to the production of microneedle patches, the production of other sheet-like materials has basically the same problems, such as sheet-like cosmetic products such as silicone sheets, facial masks, and the like.

Therefore, there is a need to develop an apparatus and a method for preparing a sheet-like material, so as to solve the technical problems in the prior art.
