1. Form til en sprøjte omfattende en kernecylinder (2) til at forme den indvendige omkreds af en sprøjte med en forbindelsesnot (G) til at blande to medicinske midler, kendetegnet ved, at kernecylinderen (2) omfatter et skabelonbeholderrum (2F), der strækker sig aksialt, en udgående kølemiddelcirkulation (2G) og en tilbagegående kølemiddelcirkulation (2H), som adskilles af den udvendige omkreds af skabelon-beholderrummet (2F) og er i forbindelse med hinanden ved kernecylinderens (2) spidsdel, og en eller flere slidser (2J, 2J, 2J), som er forbundet med ska-belonbeholderrummet (2F) og har åbninger på kernecylinderens (2) omkreds, hvor den ene eller de flere glidekerner (5, 5, 5; 7, 7) respektivt er indsat i den ene eller de flere slidser (2J, 2J, 2J), hvilket gør glidningen i kernecylinderens (2) radiale retning mulig for at danne forbindelsesnoten (G), hvor skabelonbeholderrummet (2F) indeholder en glidekerneaktiveringsska-belon (4), som befinder sig i indgreb med glidekernerne (5, 5, 5; 7, 7), og glidekernerne (5, 5, 5; 7, 7) er sat i den position, hvor glidekernerne (5, 5, 5; 7, 7) rager frem fra kernecylinderens (2) omkreds og den position, hvor glidekernerne (5, 5, 5; 7, 7) rager ind i kernecylinderens (2) omkreds ved at bevæge glidekerneaktiveringsskabelonen (4) frem og tilbage i kernecylinderens (2) aksiale retning.
2. Form til en sprøjte ifølge krav 1, hvor kernecylinderen (2) har flere slidser (2J, 2J, 2J), som er udformet på kernecylinderens (2) omkreds i regelmæssige vinkelintervaller, hvor hver af glidekernerne (5, 5, 5; 7, 7) er respektivt indsat i hver af slidserne (2J, 2J, 2J), og glidekernerne (5, 5, 5; 7, 7) befinder sig i indgreb med glidekerneaktiveringsskabelonen (4).
3. Form til en sprøjte ifølge krav 1 eller 2, hvor glidekerneaktiveringsskabelo-nen (4) er udformet i en stavform med en eller flere skrå linjer, som befinder sig i indgreb med en eller flere glidekerner (5, 5, 5; 7, 7) ved hjælp af en sva-lehalenotmekanisme.
4. Form til en sprøjte ifølge krav 1 eller 2, hvor glidekerneaktiveringsskabelo-nen (4) er dannet af en formbibeholdende trådstav (6) med en skrå linje, som befinder sig i indgreb med glidekernen (7, 7), hvilket muliggør glidningen.
