Title (EN) METHOD FOR MANUFACTURING A CANNULA UNIT
(FR) PROCÉDÉ DE FABRICATION D'UNE UNITÉ DE CANULE
Abstract:
(EN) Disclosed is a method for manufacturing a cannula unit (1) with a cannula housing and a cannula, comprising the steps: - injection molding of a cannula (3) onto a molding core pin with outer diameter d1, wherein the cannula has a distal end (32) with an outer diameter that is larger than the outer diameter of the remaining cannula, a first distal section adjoining the distal end, a second proximal section adjoining the first distal section, and a proximal end; - injection molding of a cannula housing (2) onto the distal end and the first distal section of the cannula; - removing the molding core pin from the cannula; and - threading a piercing needle (5) with outer diameter d4 into the cannula, wherein the diameter d4 of the piercing needle is chosen such that it is smaller than the diameter d1 of the molding core pin.
(FR) L'invention concerne un procédé de fabrication d'une unité de canule (1) avec un logement de canule et une canule, comprenant les étapes consistant à : - mouler par injection une canule (3) sur une broche de noyau de moulage ayant un diamètre externe d1, la canule ayant une extrémité distale (32) ayant un diamètre externe qui est plus grand que le diamètre externe de la canule restante, une première section distale adjacente à l'extrémité distale, une seconde section proximale adjacente à la première section distale, et une extrémité proximale; - mouler par injection un logement de canule (2) sur l'extrémité distale et la première section distale de la canule; - retirer la broche de noyau de moulage de la canule; et - enfiler une aiguille de perçage (5) ayant un diamètre externe d4 dans la canule, le diamètre d4 de l'aiguille de perçage étant choisi de telle sorte qu'il est plus petit que le diamètre d1 de la broche de noyau de moulage.
