要約
(EN)
A protective device (14) is attached to a medical instrument (12) provided with a needle (16) and a needle holding part (28), and covers a needle tip (16a) after puncturing of a puncture object by the needle (16). The protective device (14) includes an inner cylinder (36), an outer cylinder (40), and a spring (38), and the outer cylinder (40) receives a cam structure (54) of the inner cylinder (36) and has a guide passage structure (68) configured from one or more guide passages (66). The outer cylinder (40) is provided with a lateral top part (84b) and a distal-end inclined edge part (84d) as resistance force generating parts for causing the inner cylinder (36) to generate a resistance force at a puncture position (92a) or in the vicinity of the puncture position (92a).

La présente invention concerne un dispositif de protection (14) fixé à un instrument médical (12) pourvu d'une aiguille (16) et d'une partie de maintien d'aiguille (28), et recouvrant une pointe d'aiguille (16a) après la perforation d'un objet de perforation par l'aiguille (16). Le dispositif de protection (14) comprend un cylindre interne (36), un cylindre externe (40), et un ressort (38). Le cylindre externe (40) reçoit une structure de came (54) du cylindre interne (36) et présente une structure de passage de guidage (68) conçue à partir d'un ou de plusieurs passages de guidage (66). Le cylindre externe (40) comporte une partie supérieure latérale (84b) et une partie de bord inclinée d'extrémité distale (84d) en tant que parties de génération de force de résistance pour amener le cylindre interne (36) à générer une force de résistance au niveau d'une position de perforation (92a) ou au voisinage de la position de perforation (92a).
