Abstract

En spylesprøytesammenstilling (20) innbefatter et hus (21) som inkluderer en sylindrisk sidevegg (22) med en innvendig overflate (23) som definerer et kammer (25) for bibeholdelse av fluid, en åpen proksimal ende (27) og en fjern ende (28) med en passasje derigjennom i fluidkommunikasjon med kammeret (25). Et stempel (37) inkludert en langstrakt hoveddel (38) med en stopper (41) i sin fjerne ende (40) er tilveiebragt. Stopperen (41) er glidbart anordnet i fluidtett kontakt med den innvendige overflaten (23) av huset (21) for å drive fluid ut av kammeret (25) gjennom passasjen. Stopperen (41) inkluderer en fjern del (62) og en proksimal del (61) adskilt ved hjelp av et fjærelement (63) og konfigurert for å komprimeres når fluid blir drevet gjennom passasjen ved hjelp av bevegelsen a til stempelet (37) og å fortsette å drive fluidet gjennom passasjen etter at bevegelsen av stempelet (37) har stoppet.
