A single use lancet device (10) having a housing (20), a lancet (24) with a piercing tip (25) movably disposed in the housing (20) and structured to move between a cocked orientation and a piercing orientation, and a driving assembly structured to move the lancet (24) into the piercing orientation. A retention member and an engagement hub are further provided and structured to be cooperatively engaged with one another upon the lancet being disposed in the cocked orientation so as to maintain the lancet in the cocked orientation until released by an actuation assembly (40). Specifically, the actuation assembly (40) is structured to move between an actuated and an unactuated orientation, movement into the actuated orientation releasing the retention member and the engagement hub from their cooperative engagement with one another and thereby result in movement of the lancet into the piercing orientation. The device also includes a restrictor assembly structured to substantially prevent the actuation, assembly from moving out of the actuated orientation, thereby preventing re-firing of the lancet utilizing the actuation assembly.
L'invention concerne un dispositif à lancette à usage unique (10) qui comprend un boîtier (20), une lancette (24) dotée d'une pointe de percement (25) montée mobile dans le boîtier (20) et conçue pour se déplacer entre une position armée et une position de percement, ainsi qu'un ensemble d'entraînement conçu pour amener la lancette (24) dans la position de percement. De plus, un élément de retenue et un moyeu d'accouplement coopèrent par contact réciproque lorsque la lancette est placée dans la position armée et la maintiennent dans cette position jusqu'à sa libération par l'ensemble de commande (40). Plus particulièrement, l'ensemble de commande (40) se déplace entre une position finale et une position non finale. Le déplacement dans la position finale permet de séparer l'élément de retenue et le moyeu d'accouplement l'un de l'autre, ce qui amène la lancette dans sa position de percement. Ce dispositif comprend par ailleurs un ensemble de restriction qui empêche sensiblement l'ensemble de commande de s'écarter de la position finale, ce qui rend inutile le réarmement de la lancette via ce même ensemble.
