Abstract
Mechanizm sterujący wstrzykiwacza do podawania dawki leku obejmujący: zespół nastawiania dawki, pokrętło (1), obrotowy i nieprzesuwny osiowo element sprzęgający (2), który na końcu proksymalnym jest sprzężony w obrocie z pokrętłem (1), zaś na końcu dystalnym współpracuje z zespołem nastawiania dawki, obrotowe tłoczysko (3) zaopatrzone w gwint zewnętrzny (3.2), umieszczone wewnątrz elementu sprzęgającego (2), element napędowy (4) i sprężynę napędową (5), w którym podczas nastawiania dawki pokrętłem (1), element sprzęgający (2) obraca się napinając sprężynę napędową (5), natomiast element napędowy (4) i tłoczysko (3) są unieruchomione, zaś podczas podawania dawki, wskutek rozprężania sprężyny napędowej (5) element napędowy (4) obraca się wraz z tłoczyskiem (3), które przesuwa się osiowo w kierunku dystalnym, przy czym tłoczysko (3) jest wydrążone i zaopatrzone w gwint wewnętrzny, natomiast wewnątrz tłoczyska (3) znajduje się wałek (21) zaopatrzony w gwint zewnętrzny współpracujący z gwintem wewnętrznym tłoczyska (3), przy czym wałek (21) jest sprzężony w obrocie z elementem sprzęgającym (2) i podczas nastawiania każdej kolejnej dawki obraca się względem tłoczyska (3) i przesuwa osiowo w kierunku proksymalnym, zaś podczas podawania dawki wałek (21) jest nieruchomy względem tłoczyska (3), natomiast sumaryczne przemieszczenie wałka (21) względem tłoczyska (3) wskutek nastawienia określonej liczby dawek ma zakres ograniczony za pomocą środków blokujących (B) znajdujących się odpowiednio na tłoczysku i na wałku. Wstrzykiwacz do podawania dawki leku zawierający ujawniony mechanizm sterujący.
