Problems solved by technology

However, due to the extremely small size of the microneedles, the protrusions may produce burrs during extrusion, and it is not easy to form a uniform hole diameter with a laser, whether it is off-axis perforation or central perforation

Abstract

The invention discloses a percutaneous microneedle array patch and a manufacturing method thereof for measuring the concentration of subcutaneous target molecules, comprising: a substrate, a microneedle unit, a signal processing unit and a power supply unit. The microneedle unit at least includes a first microneedle group arranged on the substrate as a working electrode and a second microneedle group as a reference electrode, each microneedle group includes at least one microneedle, and the first microneedle group includes at least one sheet, At least one perforation is provided on each sheet, and a thorn is provided on the edge of the perforation, wherein the perforation on one sheet allows the thorns on the opposite position of the perforation edge on the other sheets to pass through, and the thorns are separated from each other. In the percutaneous microneedle array patch of the present invention, when the microneedles of the microneedle group puncture the skin for sensing, the microneedles can remain intact.

Description

technical field [0001] The invention relates to a percutaneous microneedle array patch, in particular to a percutaneous microneedle array patch for measuring the concentration of target molecules under the skin to obtain physiological signals of a human body. Background technique [0002] The subcutaneous tissue is the main place for the flow and distribution of human interstitial fluid. Interstitial fluid is rich in amino acids, sugars, fatty acids, coenzymes, hormones, neurotransmitters, salts, and wastes produced by cells. It is the main channel for cells to communicate with blood. The concentration of each component in interstitial fluid is one of the methods used to judge the physiological condition. [0003] When taking or injecting drugs, the drugs will be released slowly and for a long time in the interstitial fluid. During the clinical trials of drug development and use, it is often necessary to continuously monitor the changes in the concentration of the drug in th...
