Problems solved by technology
[0003] Most of the existing polymer material microneedles are produced by injection molding or wire drawing. Because the product uniformity of the wire drawing process cannot be guaranteed, the injection molding process is selected as the production route.
The existing injection molding process for microneedle modules is to set a mold to inject a single microneedle module, take off the male mold after it is dried and formed, and then remove the microneedle module from the female mold. Due to the small diameter, the force applied to the ejection of the microneedles can sometimes cause damage to the microneedles
The existing microneedle injection molding process has the following defects: 1. Slow production speed and low degree of mechanization; 2. Low yield; 3. Difficult demoulding, which affects production speed; 4. The demoulding process is too complicated to be mechanized quickly

The invention belongs to the field of biomedical engineering technology and equipment manufacturing, and particularly relates to manufacturing equipment and method of a microneedle module. According to the manufacturing equipment and method of the microneedle module, injection molding is carried out on a microneedle through an integrated mold, and an adhesive is arranged between a base cavity and a microneedle cavity, so that the microneedle module is prevented from being scrapped due to the influence of demolding force, the demolding speed can be increased, the microneedle injection molding process is more suitable for mechanical and industrial production of the microneedle, and the yield can be improved.
Description
technical field [0001] The invention belongs to the field of biomedical engineering technology and equipment manufacturing, and in particular relates to a manufacturing equipment and a manufacturing method of a microneedle module. Background technique [0002] Microneedle technology is a drug delivery method that has received extensive attention in recent years. It solves the pain of injection and the problem that biological macromolecules cannot be administered orally, and also surpasses the current situation that traditional transdermal drug delivery is only suitable for small molecules and lipophilic agents and has low utilization rate. [0003] Most of the existing polymer material microneedles are produced by injection molding or wire drawing. Because the product uniformity of the wire drawing process cannot be guaranteed, the injection molding process is selected as the production route. The existing injection molding process for microneedle modules is to set a mold t...
