The invention provides a manufacturing device and method of microarray transdermal drug delivery microneedles. The manufacturing device of the microarray transdermal drug delivery microneedles comprises a mold with preset flexibility, a pressure applying device and an input device. The bottom of the mold is placed on a workbench, a plurality of grooves are formed in the top of the mold, and the shape of each groove is matched with that of the microneedles. The pressure applying device is detachably arranged on the mold and applies pressure to the grooves, so that the grooves are in a closed state. The input device is detachably arranged at the top of the mold, liquid is injected into the grooves after the grooves are in a closed state, and the liquid in each groove forms the microneedles after being solidified. According to the manufacturing device and method of the microarray transdermal drug delivery microneedles, the shape of each groove is matched with the shape of the microneedles to be manufactured, the input device injects the liquid into each groove to manufacture the microneedles with the required shape and size, the shape of the microneedles can be accurately controlled, each groove can be closed under the action of the pressure applying device, the input device can conveniently inject the liquid into each groove, the liquid can be manufactured into the microneedles only by solidification, and the effect and the quality of the microneedles are ensured.
Description
technical field [0001] The invention relates to the technical field of medical equipment, in particular to a manufacturing device and method of a microarray transdermal drug delivery microneedle. Background technique [0002] At present, the use of biodegradable microarray drug delivery is a painless transdermal drug delivery technology, which can painlessly create micron-scale drug delivery channels on the skin, so that drugs or active ingredients can be introduced into the skin through the natural cuticle of the skin It is then absorbed, enhancing the skin's permeability to active substances or drugs, especially macromolecular drugs. Therefore, the application of dissolvable microneedles is more extensive. [0003] The existing manufacturing process of dissolvable microneedles is mainly the stretching and shaping method. The stretching and shaping method is to form a microneedle structure by contacting and stretching viscous polymer droplets. characteristics, so the shap...
