CA 2613255

The device comprises a body (2) and placed therein a needle assembly (1) and a push button (3) located in the upper portion of the body (2), whereas the needle assembly (1) has in its lower portion a sheathed piercing needle (5), and the push button (3) has in its upper portion a press surface, and between the body (2) and the needle assembly (1) a return spring (27) is placed. The push button (3) is coupled with the needle assembly (1) by means of abutting surface elements (15, 44), whereas during the movement of the push button (3) and after resting the needle assembly (1) on the element (20) of the body (2) and after performing the full-depth piercing, one of the abutting surface elements (15, 44) bends, releasing the needle assembly (1) from the thrust of the push button (3), whereupon the needle assembly (1) retracts to the inside of the body by means of the return spring (27).

La présente invention a trait à un dispositif, qui comprend un corps (2), dans lequel sont placés un ensemble aiguille (1) et un bouton poussoir (3) se trouvant dans la partie supérieure du corps (2). L'ensemble aiguille (1) possède une aiguille perforante gainée (5) dans sa partie inférieure, le bouton poussoir (3) possède une surface de pression dans sa partie supérieure, et un ressort de rappel (27) est placé entre le corps (2) et l'ensemble aiguille (1). Le bouton poussoir (3) est couplé à l'ensemble aiguille (1) à l'aide d'éléments de surface contigus (15, 44). Lors du déplacement du bouton poussoir (3), après que l'ensemble aiguille (1) vienne reposer sur l'élément (5) du corps (2), et après la réalisation d'une perforation pleine profondeur, l'un des éléments du surface contigus (15, 44) se courbe, ce qui libère l'ensemble aiguille (1) de la poussée du bouton poussoir (3), et permet à l'ensemble aiguille (1) de rentrer à l'intérieur du corps à l'aide du ressort de rappel (27).
