Abstract

Przedmiotem zgłoszenia jest przesuwny mechanizm wyzwalający automatycznej strzykawki z kształtowym elementem blokującym zawierający tłoczysko (4) oparte częścią dystalną o wierzch tłoka ampułki, na którym to tłoczysku (4) znajduje się sprężyna (6) mechanizmu uderzeniowego oparta częścią proksymalną o wewnętrzną cześć obudowy (1) strzykawki w jej proksymalnej części, nad którą względem części dystalnej zamocowany jest mechanizm wyzwalający, gdzie proksymalna cześć tłoczyska (4) zawiera rozszerzające się w kierunku części proksymalnej strzykawki wytoczenie, w którym osadzony jest pierścień spustowy (5) składający się z co najmniej dwóch elementów, nad którym względem części dystalnej znajduje się grzybek, będący częścią wierzchnią tłoczyska (4), gdzie przycisk (7) zwalniający jest osadzony na proksymalnej części obudowy (1) i utrzymywany poprzez znajdujący się w jego dystalnej części wyprofilowany do wewnątrz pierścień blokujący (7a) będący spodnią częścią przycisku (7), osadzony na kołnierzu (1a) obudowy oraz sprężynę (8) mechanizmu zwalniającego znajdującą się pomiędzy obudową przycisku (7) a obudową (1), która to sprężyna (8) oplata proksymalną cześć obudowy (1) i opiera się ze swoją częścią proksymalną o spodni - dystalny element przycisku (7) oplatający pierścień spustowy (5) oraz częścią dystalną o cześć obudowy (1) tworzącą kołnierz (1a), gdzie w spoczynkowej pozycji grzybek opiera się o krawędzie pierścienia spustowego (5), a w pozycji roboczej grzybek przesuwa się wewnątrz obudowy (1) przechodząc przez rozdzielone elementy pierścienia spustowego (5), poprzez wciśniecie przycisku (7) zwalniającego co powoduje zwolnienie sprężyny (6) i wyzwolenie mechanizmu uderzeniowego strzykawki z igłą.The subject of the application is a sliding trigger mechanism of an automatic syringe with a shaped locking element comprising a piston rod (4) supported by its distal part on the top of the ampoule piston, on which piston rod (4) there is a spring (6) of the impact mechanism supported by its proximal part on the inner part of the housing (1) of the syringe in its proximal part, over which, in relation to the distal part, a trigger mechanism is mounted, wherein the proximal part of the piston rod (4) comprises a recess widening towards the proximal part of the syringe, in which a trigger ring (5) consisting of at least two elements is mounted, over which, in relation to the distal part, a mushroom is located, being the top part of the piston rod (4), wherein the release button (7) is mounted on the proximal part of the housing (1) and held by a locking ring (7a) profiled towards the inside located in its distal part, being the bottom part of the button (7), mounted on the collar (1a) of the housing, and a spring (8) of the release mechanism located between the button housing (7) and the housing (1), wherein the spring (8) wraps around the proximal part of the housing (1) and rests with its proximal part on the lower - distal element of the button (7) surrounding the trigger ring (5) and the distal part on the part of the housing (1) forming the collar (1a), where in the rest position the head rests on the edges of the trigger ring (5), and in the working position the head moves inside the housing (1) passing through the separated elements of the trigger ring (5), by pressing the release button (7), which causes the release of the spring (6) and the triggering of the syringe with the needle impact mechanism.
