1. Drivindretning (180) til en lægemiddeladministreringsanordning (101), hvilken drivindretning omfatter en fjederdel (127), en stempelstang (102) og en stempelstangsmøtrik (126), der er i indgreb med stempelstangen (102), hvor stempelstangsmøtrikken (126) er konfigureret til at rotere og bevæges aksialt under en indstilling af en dosis, hvor fjederdelen (127) komprimeres, når stempelstangsmøtrikken (126) bevæges under indstillingen af en dosis, hvor stempelstangsmøtrikken (126) er rotationsfikseret under en dispensering af en dosis, og hvor drivindretningen (180) yderligere omfatter en låsedel (125) med en låst tilstand, hvor låsedelen (125) hæmmer relaksering af fjederdelen (127), når låsedelen (125) er i dens låste tilstand, der er kendetegnet ved, at låsedelen (125) er i gevindindgreb med stempelstangen (102). 2. Drivindretning ifølge krav 1, hvor stempelstangen (102) kan bevæges aksialt, men er rotationsfikseret under en dispensering af en dosis. 3. Drivindretning ifølge krav 1 eller 2, hvor fjederdelen (127) berører stempelstangsmøtrikken (126). 4. Drivindretning ifølge et hvilket som helst af ovennævnte krav, hvor stempelstangsmøtrikken (126) er konfigureret til at udføre en aksial, ikke-roterende bevægelse under dispensering af en dosis. 5. Drivindretning ifølge et hvilket som helst af ovennævnte krav, hvor fjederdelen (127) er en spiralfjeder. 6. Drivindretning ifølge et hvilket som helst af ovennævnte krav, hvor stempelstangen (102) omfatter mindst ét gevind, og hvor stempelstangsmøtrikken (126) er i gevindindgreb med stempelstangen (102).

Drivindretning ifølge et hvilket som helst af ovennævnte krav, hvor stempelstangen (102) bevæges mod en distal ende af anordningen (111) ved hjælp af fjederdelen (127), når låsedelen (125) er frigjort fra dens låste tilstand. 9. Drivindretning ifølge et hvilket som helst af ovennævnte krav, hvor låsedelen (125) er konfigureret til at overhale stempelstangen (102) under dispensering af en dosis. 10. Drivindretning ifølge et hvilket som helst af ovennævnte krav, der omfatter en aktuator (120), der er konfigureret til at blive aktiveret til administrering af en medikamentdosis fra lægemiddeladministreringsanordningen (101), hvor fjederdelen (127) er konfigureret til at relaksere, når aktuatoren (120) aktiveres. 11. Drivindretning ifølge krav 10, hvor låsedelen (125) frigøres fra dens låste tilstand, når aktuatoren (120) aktiveres. 12. Drivindretning ifølge et hvilket som helst af ovennævnte krav, der omfatter en rotationsdel (123), hvor stempelstangsmøtrikken (126) roteres ved hjælp af en rotation af rotationsdelen (123) under indstillingen af en dosis. 13. Drivindretning ifølge et hvilket som helst af ovennævnte krav, der omfatter en indikator (128), der er konfigureret til at vise mængden af en indstillet dosis. 14. Lægemiddeladministreringsanordning (101), der omfatter en drivindretning ifølge et hvilket som helst af kravene 1 til 13.
