CA 2197671

An aspirator assembly designed to remove fluids from the human body comprises an elongated hollow interior barrel plunger reciprocally movable and slidably engageable within the barrel along the length thereof. The plunger includes an elongated stem having a grip (4) at an outer end thereof and a plunger head secured to an inner end of the stem. The improvement is found in a locking device which is selectively positionable into and out of a locked position. The locking device is formed in part on both the barrel and the stem and is adapted for removably locking the plunger head in a plurality of spaced apart locations (5) within and along the length of the barrel. Additionally, the stem may be rotated so as to disengage the locking device and provide an aspirator with unobstructed reciprocation.

Un dispositif aspirateur réalisé pour prélever des fluides du corps humain comporte un cylindre creux allongé avec un piston s'engageant dans le cylindre et mobile par rapport à celui-ci, dans les deux directions. Le piston a une tige allongée avec un moyen de préhension (4) fixé à l'extrémité externe et une tête de piston fixée à l'extrémité interne de la tige. L'amélioration concerne un dispositif de verrouillage qui peut être mis à volonté en position active ou en position inactive. Le dispositif de verrouillage est formé sur le cylindre et sur la tige et il permet de verrouiller d'une manière réversible la tête de piston dans une pluralité de positions espacées (5) suivant la longueur du cylindre. On tourne la tige pour désengager le dispositif de verrouillage et permettre un déplacement libre de la tige dans les deux sens.
