Title (EN) DUAL-CHAMBER SYRINGE
(FR) SERINGUE À DOUBLE CHAMBRE
Abstract: front page image
(EN)Syringe (10) for discharging two components comprises a housing (12)d, a piston (20) at least partly inside said housing and axially moveable relative thereto between a first and a second position, a hollow cylindrical container (22) at least partly inside said housing, surrounding said piston and axially moveable relative to said piston between a first and a second position, a first compartment (24) defined within said housing between the distal end of said piston assuming its first position and the distal end of said housing for receiving a first component (28), a second compartment (30) defined within said container assuming its first position between the proximal end of said container and the proximal end of said piston for receiving a second component (36), an axially extending passage (38) in the interior of said piston and in communication with said first compartment and a radial opening (40) of said piston in the region of the proximal end of said piston, sealing means (52) for preventing communication between said second compartment and said radial opening of said piston when the container assumes its first position, and releasable retaining means (44) for retaining said piston in its first position until said container has reached its second position. The syringe is further adapted so that communication between said second compartment and said radial opening of said piston is established after initiation of the movement of said container out of its first position towards its second position relative to said piston, thereby transferring said second component from said second compartment into the radial opening and through the axial passage of the piston into said first compartment, said retaining means are released by said container reaching its second position, and with the further movement of said container into said housing and the simultaneous movement of the released piston out of its first position towards its second position, the two mixed components are pressed out of said first compartment.
(FR)L'invention concerne une seringue (10) qui permet d'évacuer deux constituants et qui comprend un logement (12)d, un piston (20) au moins partiellement à l'intérieur dudit logement et mobile de façon axiale par rapport à celui-ci entre des première et seconde positions, un récipient cylindrique creux (22) au moins partiellement à l'intérieur dudit logement, entourant ledit piston et mobile de façon axiale par rapport audit piston entre des première et seconde positions, un premier compartiment (24) délimité à l'intérieur dudit logement entre l'extrémité distale dudit piston adoptant sa première position et l'extrémité distale dudit logement pour recevoir un premier constituant (28), un second compartiment (30) délimité à l'intérieur dudit récipient adoptant sa première position entre l'extrémité proximale dudit récipient et l'extrémité proximale dudit piston pour recevoir un second constituant (36), un passage s'étendant de façon axiale (38) à l'intérieur dudit piston et en communication avec ledit premier compartiment et une ouverture radiale (40) dudit piston dans la région de l'extrémité proximale dudit piston, un moyen d'étanchéité (52) pour empêcher une communication entre ledit second compartiment et ladite ouverture radiale dudit piston lorsque le récipient adopte sa première position, et un moyen de retenue libérable (44) pour retenir ledit piston dans sa première position jusqu'à ce que ledit récipient ait atteint sa seconde position. La seringue est en outre conçue de telle sorte qu'une communication entre ledit second compartiment et ladite ouverture radiale dudit piston est établie après le début du mouvement dudit récipient hors de sa première position vers sa seconde position par rapport audit piston, en transférant ainsi ledit second constituant dudit second compartiment dans l'ouverture radiale et à travers le passage axial du piston dans ledit premier compartiment, ledit moyen de retenue étant libéré par ledit récipient atteignant sa seconde position et, avec un autre mouvement dudit récipient dans ledit logement et le mouvement simultané du piston libéré de sa première position vers sa seconde position, les deux constituants mélangés sont pressées hors dudit premier compartiment.
