Definitions
- the nano-chips in the medicinal solution introduction head of the present invention are directly embedded on the working surface of the introduction head body, which avoids the combination of the introduction head body by means of glue, and overcomes the defects of the fixing method of glue. , Which facilitates the assembly and fixation of nano wafers.
Abstract
L'invention concerne une tête d'introduction de liquide médicinal, comprenant : un corps de tête d'introduction, une face d'extrémité d'une extrémité de celui-ci formant une face de travail, et le corps de tête d'introduction étant formé d'un seul tenant au moyen d'un moulage par injection ; et une tranche nanométrique qui comprend une base et des micro-aiguilles disposées sur la base, la tranche nanométrique étant directement incorporée dans une rainure de montage formée pendant le moulage par injection du corps de tête d'introduction, et les micro-aiguilles sur la tranche nanométrique faisant saillie hors de la face de travail. La tranche nanométrique dans la tête d'introduction de liquide médicinal du présent modèle d'utilité est directement incorporée dans la face de travail du corps de tête d'introduction, et évite la combinaison de celle-ci avec le corps de tête d'introduction au moyen d'un adhésif, ce qui permet de surmonter le défaut se produisant lorsque la tranche nanométrique est fixée au moyen de l'adhésif et de faciliter l'assemblage et la fixation de la tranche nanométrique.
