Claims (15)
1. Drivmekanisme til en medicinleveringsanordning til at indstille og afgive en dosis af medikament, idet mekanismen omfatter: - en indeslutning (20), - en stempelstang (120) til operativt at gribe ind med et stempel (14) fra en patron (12) for at forskyde stemplet (14) i en retning (1) mod det fjerne, - et dosisindikerende element (40) med en information (48) om dosisstørrelse derpå, der er drejelig i en retning (5) af forøget dosis til at indstille en dosis, et drivhjul (130), der er operabelt i indgreb med stempelstangen (120) til at forskyde stempelstangen (120) i retning (1) mod det fjerne for afgivelse af dosis, kendetegnet ved, at det dosisindikerende element (40) er forbundet med et fjederelement (100) og er drejeligt i retningen (5) af forøget dosis imod virkningen af fjederelementet (100), og hvori det dosisindikerende element (40) kan bringes i indgreb med drivhjulet (130) under afgivelse af dosis for at overføre en drivende kraft til drivhjulet (130), når det bliver drevet af det afslappende fjederelement (100) i en retning (6) af formindsket dosis.
2. Drivmekanisme ifølge krav 1, hvori det dosisindikerende element (40) omfatter en flad facongivet, dosisindikerende skive.
3. Drivmekanisme ifølge et hvilket som helst af de foregående krav, hvori fjederelementet (100) omfatter en spiralfjeder, der har et første endeafsnit (101) forbundet med indeslutningen (20, 90) og har et andet endeafsnit (102) forbundet med det dosisindikerende element (40).
4. Drivmekanisme ifølge et hvilket som helst af de foregående krav, der yderligere omfatter et ringformet dosisindstillende element (30), som er drejeligt understøttet af indeslutningen (20) og kan selektivt bringes i indgreb med det dosisindikerende element (40) for at indstille en dosis.
5. Drivmekanisme ifølge et hvilket som helst af de foregående krav, der yderligere omfatter et dosisafgivende element (70), som er drejeligt fastgjort til indeslutningen (20) og kan trykkes ned i en aksial retning (4) imod virkningen af et afgivende fjederelement (84).
6. Drivmekanisme ifølge krav 5, hvori det dosisindikerende element (40) ligger aksialt an med det dosisafgivende element (70) .
7.
