Claims (9)
1. Drivmekanisme til en lægemiddeldispenseringsanordning, der omfatter: - en ledeskrue (5), en ledeskruemøtrik (7) og en drivdel (8), der er på linje med en akse (4), der definerer en aksial retning og en modsat aksial retning, - hvor en kobling mellem ledeskruen (5) og ledeskruemøtrikken (7) åbner mulighed for en skruebevægelse af ledeskruen (5) i forhold til ledeskruemøtrikken (7) mindst i den aksiale retning, - hvor ledeskruen (5) er koblet med drivdelen (8), hvilken kobling frembringer en skruebevægelse af ledeskruen (5) i forhold til drivdelen (8), når drivdelen (8) bevæges i den aksiale retning i forhold til ledeskruen (5) , og koblingen tilsidesættes til forhindring af en skruebevægelse af ledeskruen (5) i forhold til drivdelen (8), når drivdelen (8) bevæges i den modsatte aksiale retning i forhold til ledeskruen (5), - et dispenseringsstoptræk (19) på ledeskruemøtrikken (7) og - et dispenseringsstoptræk (20) på drivdelen (8), - hvilke dispenseringsstoptræk (19, 20) interagerer og derved forhindrer frembringelsen af skruebevægelsen af ledeskruen (5), når drivdelen (8) nærmer sig en specificeret slutposition, der er kendetegnet ved, at dispenseringsstoptrækkene (19, 20) har tilsvarende kontaktflader (22), der er skrå på aksen (4).
2. Drivmekanisme ifølge krav 1, hvor dispenseringsstoptrækkene (19, 20) har tilsvarende endeflader (23), der hæmmer en rotation af drivdelen (8) i forhold til ledeskruemøtrikken (7) i mindst én retning.
3. Drivmekanisme ifølge et af kravene 1 til 2, hvor dispenseringsstoptrækket (19) på ledeskruemøtrikken (7) har form som en prisme eller en afkortet prisme.
4. Drivmekanisme ifølge et af kravene 1 til 3, hvor dispenseringsstoptrækkene (19, 20) styrer drivdelen (8) i forhold til ledeskruemøtrikken (7) i en skruebevægelse med den samme stigning som skruebevægelsen af ledeskruen (5) i forhold til drivdelen (8) .
5. Drivmekanisme ifølge et af kravene 1 til 4, der yderligere omfatter: et fleksibelt styretræk (15) på ledeskruen (5) og et skruegevind (18) på drivdelen (8), hvor koblingen af ledeskruen (5) med drivdelen (8) tilvejebringes af, at det fleksible styretræk (15) går i indgreb med skruegevindet (18), og hvor skruegevindet (18) har den samme stigning som skruebevægelsen af ledeskruen (5) i forhold til drivdelen (8).
6. Drivmekanisme ifølge et af kravene 1 til 5, der yderligere omfatter: stoptræk (17) på ledeskruen (5), hvilke stoptræk (17) hæmmer skruebevægelsen af ledeskruen (5), når drivdelen (8) bevæges i den modsatte aksiale retning i forhold til ledeskruen (5) .
7. Drivmekanisme ifølge et af kravene 1 til 6, hvor drivdelen (8) og ledeskruemøtrikken (7) er rotationslåst.
8. Drivmekanisme ifølge et af kravene 1 til 7, hvor dispenseringsstoptrækket (19) på ledeskruemøtrikken (7) er formet som en integreret del af ledeskruemøtrikken (7), og dispenseringsstoptrækket (20) på drivdelen (8) er formet som en integreret del af drivdelen (8).
9. Lægemiddeldispenseringsanordning, der omfatter: - en drivmekanisme ifølge et af kravene 1 til 8 og - et legeme (1) med en distal ende (2) og en proksimal ende (3), der er adskilt fra hinanden i retningen af aksen (4) .
