Abrégé
(EN)
A skin pricker is disclosed which comprises a casing (100) and a plunger (132) which fit together telescopically. To trigger the skin pricker, the plunger's head (134) is placed against the skin to be pricked and the casing (100) pressed towards it. A lancet blade (114) is mounted on an element (112) which is integral with a spring (118). The spring is sinusoidal and includes stops (126, 128, 130) for limiting movement of the 'waves' of the spring towards one another. Cams (116) carried by the element (112) co-operate with the end surfaces of plates (138) forming part of the plunger so that during initial movement of the casing, the plunger and element move as a unit. When the stops (126, 128, 130) prevent further movement of the element, the cams urge the plates apart and then enter slots (140) in the plates (138). The spring then forces the blade (114) in a forward skin pricking movement. The cams (116) enter in the plates (138) and can move freely along the slots. Thus the plunger (132), even if pushed back into the casing (100), cannot recompress the spring (110).
(FR)
L'invention concerne un support de lancettes intradermiques, constitué d'un corps (100) et d'un piston (132) qui s'adaptent l'un à l'autre de manière télescopique. Afin de déclencher le support de lancettes, on place la tête (134) du piston contre la peau à piquer et on pousse le corps vers le bas en direction de la tête. Une lame (114) est fixée sur un élément (112) formé en monobloc avec un ressort (118) sinusoïdal. Le ressort comporte des butées (126, 128, 130) qui limitent le rapprochement de ses spires. Des cames (116) portées par l'élément (112) coopèrent avec les surfaces terminales de plaques (138) faisant partie du piston, de façon que durant le déplacement initial du corps, le piston et l'élément se déplacent comme une seule unité. Quand les butées (126, 128, 130) empêchent l'élément de continuer à se déplacer, les cames séparent les plaques puis entrent dans des fentes (140) creusées dans les plaques (138). Le ressort impose ensuite à la lame (114) un déplacement vers l'avant, de façon à piquer la peau. Les cames (116) entrent dans les plaques (138) et peuvent se déplacer librement dans les fentes. Ainsi, même s'il est poussé de façon à revenir dans le corps (100), le piston (132) ne peut pas recomprimer le ressort (110).
