ABSTRACT:
Apparatus for manufacturing an injection needle having a hub and a cannula whose back end terminates within the hub. The apparatus includes a first subassembly jig for mounting the hub, inserting a cannula into a center hole of the hub, and securing the hub and cannula together with an adhesive. A silicone-containing-liquid is applied to the back end of the hub-cannula assembly. A second subassembly jig is provided for mounting the hub-cannula assembly to remove excess silicone-containing-liquid within the cannula, covering the front end with a cap, and housing the hub-cannula-cap assembly with a container. An opening of the container is sealed after the hub-cannula-cap assembly is removed from the second subassembly jig.
