Abstract

Oppfinnelsen vedrører en sprøyte omfattende en sylinder, et stempel og en stempel- stang. Stempelet kan deformeres av stempelstangen for å trekke stempelets radielle vegger bort fra sylinderens indre vegg og således redusere friksjonen mellom stem- pelet og sylinderen, for å gjøre injiseringen lettere. Deformasjonen kan også anvendes for å aspirere sprøyten. Oppfinnelsen tilveiebringer også en fremgangs- måte for å levere et væskemedium til en pasient ved bruk av en sprøyte.
