Abstract

Przedmiotem zgłoszenia jest przesuwny mechanizm wyzwalający automatycznej strzykawki, zawierający tłok (4a) mechanizmu uderzeniowego, oparty częścią dystalną o wierzch tłoka ampułki (3), na którego tłoczysku (4) znajduje się sprężyna (5) mechanizmu uderzeniowego, oparta częścią proksymalną o wewnętrzną cześć obudowy (1) strzykawki w jej proksymalnej części, nad którą zamocowany jest mechanizm wyzwalający charakteryzujący się tym, że proksymalna cześć tłoczyska (4) zawiera wytoczenie (4b), w którym osadzony jest mechanizm spustowy (7), nad którym znajduje się grzybek (4d) będący częścią wierzchnią tłoczyska (4), o regularnym kształcie, gdzie mechanizm spustowy (7) zawiera otwór o nieregularnym kształcie utworzonym z dwóch nałożonych na siebie częściowo okręgów, których oś symetrii pokrywa się z osią symetrii mechanizmu spustowego (7), gdzie średnica mniejszego okręgu (7a) jest mniejsza od średnicy grzybka (4c), a średnica większego okręgu (7b) - sąsiadującego z przyciskiem zwalniającym (7c) - jest równa, bądź większa od średnicy grzybka (4c) w ten sposób, że wciśniecie przycisku zwalniającego (7c) powoduje przesunięcie mechanizmu spustowego (7) co doprowadza do zwolnienia sprężyny (5) i wyzwolenia mechanizmu uderzeniowego strzykawki z igłą (2).The subject of the application is a sliding trigger mechanism of an automatic syringe, comprising a piston (4a) of the impact mechanism, supported by its distal part on the top of the ampoule piston (3), on the piston rod (4) of which there is a spring (5) of the impact mechanism, supported by its proximal part on the inner part of the housing (1) of the syringe in its proximal part, above which a trigger mechanism is mounted, characterized in that the proximal part of the piston rod (4) comprises a recess (4b), in which a trigger mechanism (7) is mounted, above which there is a head (4d) being the top part of the piston rod (4), of regular shape, wherein the trigger mechanism (7) comprises an opening of irregular shape formed of two partially superimposed circles, the axis of symmetry of which coincides with the axis of symmetry of the trigger mechanism (7), where the diameter of the smaller circle (7a) is smaller than the diameter of the head (4c), and the diameter of the larger circle (7b) - adjacent to the release button (7c). - is equal to or greater than the diameter of the head (4c) so that pressing the release button (7c) causes the trigger mechanism (7) to move, which leads to the release of the spring (5) and the triggering of the syringe-needle impact mechanism (2).
