A non-invasive dissolvable microneedle patch feeding device

Abstract

The invention belongs to the technical field of micro-nano patches, and provides a non-invasive dissolvable microneedle patch feeding device, which includes a frame, and the workbench of the frame is provided with an original sheet feeding mechanism, an original sheet retrieving mechanism, an original sheet The cutting mechanism, the material take-up and torque-changing mechanism and the material-piece torque-changing placement table, the original sheet retrieving mechanism is located between the original sheet feeding mechanism and the original sheet cutting mechanism, and the two ends of the original sheet taking mechanism are respectively connected to the The original sheet feeding mechanism and the original sheet cutting mechanism correspond to each other. The material taking and torque changing mechanism is located between the original sheet cutting mechanism and the material changing torque placing platform, and the two ends of the material taking and torque changing mechanism are respectively connected to the The original film cutting mechanism and the material piece torque-changing placement table correspond to each other. The present invention can realize the automatic feeding, transfer, cutting and automatic torque conversion between the cut pieces of the soluble microneedle original piece, and the hygiene of the piece will not be affected during the processing, and the cutting efficiency and cutting efficiency are improved. The quality is greatly improved, and the placement of the back fabric on the hydrogel slide is more efficient and accurate.

Description

technical field [0001] The invention relates to the technical field of micro-nano patches, in particular to a non-invasive dissolvable microneedle patch feeding device. Background technique [0002] According to experts, in fact, only a small hole is needed for the drug to penetrate the skin. However, in the medical and beauty industries, ordinary needles are often used to pierce the drug below the dermis, causing pain and infection. The emergence of soluble microneedle patch has been widely accepted and recognized by people. After the soluble microneedle patch is attached to human skin, its nano-scale microneedles can pierce the skin and form microchannels in the stratum corneum. Drugs or cosmetic active ingredients (such as hyaluronic acid or various added anti-wrinkle, whitening and other active ingredients) reach the deep layer of the skin along the microchannel, diffuse into the dermis, and give quantitative and continuous administration. Due to the elasticity of the s...

Problems solved by technology

[0006] Specifically, the technical problem to be solved by the present invention is to provide a non-invasive dissolvable microneedle patch feeding device to solve the current manual cutting of the original soluble microneedle sheet, which has low cutting efficiency and quality. It will inevitably affect its sanitation during the cutting process, and it is not convenient for the technical problem of placing the patch on the hydrogel slide after cutting
