Patent

CA 2520609

The invention relates to pressure generating units, in particular to pressure generating unit arranged in the hand piece of a vacuum biopsy device in the form of a sirynge (2). In said units, air intake is open by a piston when said piston (5) is in the rear position thereof in the space of a vacuumed cylinder (11) which is switched for generating a superpressure, thereby initiating the outflow of a tissue liquid by the air introduced into the space of the vacuumed cylinder. For this purpose, the space of the vacuumed cylinder is connected to the space of an atmosphere pressure cylinder (12) arranged behind the piston, by means of a connection line (15), and an absorbing element (14) is placed on the piston axis.

L'invention concerne des unités de génération de pression, en particulier des unités de génération de pression montées dans la pièce à main d'un dispositif à biopsie à vide et se présentant sous la forme d'une seringue (2). Dans ces unités, lorsque le piston (5) est ramené en arrière dans l'espace de cylindre sous vide (11), lors du passage à la génération d'une surpression, l'amenée d'air est libérée par la position du piston, cela provoquant un écoulement vers l'extérieur du liquide tissulaire au moment de l'introduction d'air dans l'espace de cylindre sous vide. Il est donc proposé de mettre l'espace de cylindre sous vide en communication, par l'intermédiaire d'une conduite de communication (15), avec l'espace de cylindre sous pression atmosphérique (12), se trouvant derrière le piston, et de placer un élément absorbant (14) sur l'axe de piston.
