Abstract

[Use of the article]; The article of this creation is a puncture pressing tool. As shown in the "Cross-sectional reference diagram of the use state", the pressing tool is used to press the microneedle array sheet so that the microneedle array on the microneedle array sheet pierces the skin and infiltrates the drug into the skin. ; [Features of the creation]; From the various figures, this article is composed of components such as a main body, a cover body, a lid body, a spring, and a piston. The main body is formed by fitting two objects together. The object below the main body is a cylindrical body with a chamfered portion, and openings are formed in the upper and lower objects. The cover body covers the top of the main body, forming a circular hole in the middle. The lid body is disc-shaped, with a protrusion extending from the bottom, forming a circular The conical recess, spring and piston are installed inside the body, and the piston head is stepped and chamfered. When using this product, as shown in the "cross-sectional reference diagram of the use state", press the cover in the direction of the arrow, and press the microneedle array sheet through the piston head, so that the microneedle array can penetrate the skin to achieve the function of drug infiltration. In addition, the detailed design of this product can be more clearly seen from each cross-sectional diagram. The design method of the overall shape is based on the overall shape of the original new model, and the difference from the original new model application is that the body, cover, and piston of this case are slightly different from those of the original new model. Therefore, the difference between this case and the original case is slight and does not affect the similarity of the two cases.
