AI Technical Summary

Technical Problem

The existing micro-needle patches are difficult to firmly fit with the skin due to the inclined structure of the needle tip, which makes it difficult to overcome skin tension or fix the skin around the wound, which can easily lead to secondary cracking of the wound.

Method used

A micro-needle patch using liquid metal encapsulation is provided in the micro-needle patch, and the coupling between the pressing member and the bonding member is used to push the micro-needle to slide out of the bonding member obliquely and pierce into the skin through the slide. At the same time, a barbed structure is formed using a flexible membrane and a limiting member to fix the micro-needle.

Benefits of technology

The fit strength of the microneedle patch with the skin is improved, ensuring that the microneedle is stable and fixed on the skin, avoiding the microneedle shaking slightly during the treatment process, and enhancing the repair effect of drugs and electrotherapy on the wound.

Abstract

The invention discloses a microneedle application packaged by liquid metal, and relates to the technical field of microneedle application, the microneedle application comprises gauze, the microneedle application further comprises a first application and a second application, the first application and the second application are the same in structure and are arranged on the two sides of the gauze, and the first application comprises a pressing part and an attaching part; the microneedles are arranged below the attaching piece in a linear array mode, the interiors of the microneedles are of hollow structures, and the inclination direction of the microneedles located in the first application body is opposite to the inclination direction of the second application body. The microneedles of the two microneedle application bodies are arranged to be inclined, the inclination directions of the microneedles of the two microneedle application bodies are opposite, so that a structure similar to a clamping jaw is formed, the attaching strength of the application body and the skin of a patient is improved, meanwhile, liquid metal is added into the microneedle application bodies and powered on, an electric field is formed at the wound of the patient, and the wound of the patient is wound. Therefore, continuous electrical stimulation is performed on the wound, and wound healing is actively promoted.
