2. Drivindretning (3) ifølge krav 1, der omfatter en rotationsdel (21), der er indrettet til at blive roteret i den første retning i forhold til huset (13) under indstilling af en dosis af et medikament (5) og til at blive roteret i den anden retning i forhold til huset (13) under dispensering af dosen.
3. Drivindretning (3) ifølge krav 2, hvor rotationsdelen (21) er anbragt i en modsat side af drivdelen (20) i forhold til stopdelen (26) .
4. Drivindretning (3) ifølge krav 2 eller 3, hvor drivdelen (20) i den operationelle tilstand af drivindretningen (3) holdes i indgreb med rotationsdelen (21), og - drivdelen (20) til skift til genindstillingstilstanden af drivindretningen (3) gøres i stand til at afkoble fra rotationsdelen (21) på grund af tyngdekraften som følge af vægten af drivdelen (20).
5. Drivindretning (3) ifølge krav 2, hvor den elastiske del (31) er indrettet til at tilvejebringe en kraft til kobling af drivdelen (20) og rotationsdelen (21) i den operationelle tilstand.
6. Drivindretning (3) ifølge et hvilket som helst af kravene 2 til 5, hvor drivdelen (20) i den operationelle tilstand er indrettet til at følge rotationsbevægelsen af rotationsdelen (21) i den anden retning i forhold til huset (13) under dispensering af dosen.
7. Drivindretning (3) ifølge krav 6, hvor drivdelen (20) og rotationsdelen (21) i den operationelle tilstand er koblet til hinanden ved hjælp af en første ensrettet friktionskoblingsmekanisme, der er konfigureret til at muliggøre relativ rotationsbevægelse mellem rotationsdel (21) og drivdel (20) under rotation af rotationsdelen (21) i den første retning til indstilling af dosen og til at forhindre relativ rotationsbevægelse af rotationsdel (21) og drivdel (20) under rotation af rotationsdelen (21) i den anden retning til dispensering af dosen.
8. Drivindretning (3) ifølge et hvilket som helst af kravene 1 til 7, hvor stopdelen (26) og drivdelen (20) i den operationelle tilstand er koblet til hinanden ved hjælp af en anden ensrettet friktionskoblingsmekanisme, der er konfigureret til at forhindre relativ rotationsbevægelse mellem stopdel (26) og drivdel (20) i den første retning i forhold til huset (13) og til at muliggøre relativ rotationsbevægelse af stopdel (26) og drivdel (20) i den anden retning i forhold til huset (13).
9. Drivindretning (3) ifølge et hvilket som helst af kravene 1 til 8, hvor stopdelen (26) eller både stopdelen (26) og drivdelen (20) i genindstillingstilstanden er indrettet til at kunne bevæges i den distale retning i forhold til huset (13) på grund af tyngdekraften, idet den tværgående bane af de respektive dele (20, 26) i distal retning i forhold til huset (13) er afgrænset ved hjælp af et mekanisk stopmiddel (39).

12. Medikamentdispenseringsanordning (1), der omfatter drivindretningen (3) ifølge et hvilket som helst af ovennævnte krav og en medikamentbeholder (2), hvor medikamentbeholderen (2) er aftagelig fra et hus (13) på drivindretningen (3) og er konfigureret til at indeholde mindst én dosis af et medikament (5) .
13. Medikamentdispenseringsanordning (1) ifølge krav 12, hvor drivindretningen (3) omfatter en drivdel (20) og en stempelstang (12), idet drivdelen (20) samvirker med stempelstangen (12) til forskydning af stempelstangen (12) i en distal retning i forhold til huset (13) på drivindretningen (3) til dispensering af en dosis af et medikament (5), og hvor anordningen (1) kan skiftes fra en operationel tilstand til en genindstillingstilstand ved fjernelse af medikamentbeholderen (2) fra huset (13) på drivindretningen (3), og hvor stempelstangen (12) i genindstillingstilstanden kan bevæges i en proksimal retning ind i huset (13) på drivindretningen (3) ved at bringe anordningen (1) i en forudbestemt position.
