A device of the manual syringe type (10) for proportioning and dispensing fluid or pasty products comprises a main body (12) provided with seizing means (20) and with guide means (19) between which a cartridge member (23), having a substantially uniform, preferably cylindrical section is inserted and guided along a straight path. The device also comprises an at least partially elastic piston (24), adapted to exert a sealing action against the inner walls of the cartridge (23). The main body (12) also comprises a plunger member (21) whereon a needle (11) is fitted. After a displacement of the main body (12) relative to the cartridge (23) the plunger member (21) causes the piston (24) to slide inside the cartridge (23) for drawing a fluid or pasty product therefrom and dispensing it through the needle (11).
L'invention porte sur un dispositif du genre seringue (10) pour doser et administrer des produits liquides ou pâteux comportant un corps principal (12) muni de moyens de prise (20) et d'un élément de guidage (19) dans lequel une cartouche (23) de section sensiblement constante, de préférence cylindrique, est guidée sur une trajectoire rectiligne. Le dispositif comporte également un piston (24) au moins partiellement élastique exerçant sur la paroi intérieure de la cartouche une action assurant l'étanchéité. Le corps principal (12) comprend en outre un poussoir (21) portant une aiguille (11). Suite à un déplacement du corps principal (12) par rapport à la cartouche (23) le poussoir (21) fait coulisser le piston (24) dans la cartouche (23) pour en extraire un produit fluide ou pâteux et l'administrer via l'aiguille (11).
