Abstract

En injeksjonsanordning innbefattende et hus for å oppta en sprøyte har en boring som strekker seg fra en endeoverflate, en nål som kommuniserer med boringen gjennom endeoverflaten og et tømmestempel som er bevegbart i boringen mot endeoverflaten for å uttømme innholdet av sprøyten gjennom nålen, huset har en åpning i en ende gjennom hvilken nålen kan strekke seg, et fjærende element for å forspenne sprøyten og nålen innover fra huset, et første koblingselement er bevegbart mot den ene enden for å bevege nålen til sprøyten ut av åpningen og bevege tømmestempelet til sprøyten mot endeoverflaten, en mekanisme som kan drives for å frigjøre sprøyten slik at nålen beveger seg innover fra huset, en drivkopling for å strekke seg fra den første koblingselementet til tømmestempelet til sprøyten for å overføre bevegelse av det første koblingselementet til tømmestempelet hvor mekanismen blir utløst for å frigjøre sprøyten og innbefatter komponenter for å forsinke frigjøring av sprøyten inntil en forutbestemt tidsperiode etter å ha blitt utløst slik at det kan bli sikret at tømmestempelet når endeoverflaten før sprøyten blir frigjort og/eller mekanismen innbefatter en treghetsmasse som er bevegbar med det første koblingselementet og et frigjøringselement som kan aktiveres av treghetsmassen for å frigjøre sprøyten slik at når tømmestempelet frigjør endeoverflaten av sprøyten og det første koblingselementet og drivkobling stopper bevegelse, fortsetter treghetsmassen å beveges for å aktivere frigjøringselementet for å frigjøre sprøyten.
