Abstract

A safety module (600) for a needle (622) in a disposable cannula device, the safety module comprising two arms (602a, 602b), inclide to each other and defining a cavity between one end of each of the two arms, the cavity slidably resting against an outer surface of the needle disposed between the two arms thereby defining a first contact surface (616) between the two arms and the needle: a connecting member (604) joining the other two ends of the arms, the connecting member having a circular through hole (606) such that the center of the through hole and the first contact surface (616) define an axis (620) along which the needle moves while passing through the hole; two flange components (608a, 608b) extending from the two ends of the arms from the first contact surface (616); two module locking components (610a, 610b) extending from the two flange components.
