Abrégé
(EN)
This invention is a skin piercing device which converts a longitudinal linear motion of a blade (5) within the housing (1) of said device into a vertical linear motion, which in consequence of the placement of biasing means (6), restraints and stops (10) in the device, results in the ejection of the blade (5) out of the housing (1) and into the patient's skin and back again into the housing (1) in a rapid 'in-out' fashion. The dimensions of the restraints and stops are individually controllable, and as a result, it is possible to achieve a length of cut which is independent of the depth of cut.
(FR)
Dispositif destiné à perforer la peau, et convertissant le mouvement linéaire longitudinal d'une lame (5) dans une enveloppe (1) dudit dispositif en un mouvement linéaire vertical. Dans la mesure où l'on prévoit, dans le dispositif, un dispositif de sollicitation (6), des éléments de retenue et des butées (1'), ce mouvement vertical conduit à l'expulsion de la lame (5) hors de l'enveloppe (1) et dans la peau du patient, après quoi la lame rentre à nouveau dans l'enveloppe (1) en un mouvement rapide d'entrée-sortie. Les dimensions des éléments de retenue et des butées sont individuellement réglables, de sorte qu'il soit possible d'obtenir une incision dont la longueur est indépendante de la profondeur.
