1. Medicinsk injektor (152) der omfatter: - et legeme (154) der har en distal ende og en proximal ende; - et stempel (164) der er forskydeligt anbragt i legemet (154), kendetegnet ved, at - stemplet (164) har et antal adskilte skraldetænder (168) der er anbragt langs dets længde, hvilket stempel (164) selektivt forskyder en prop for at dispensere et medikament fra den medicinske injektor (152); - en indexer (176) der er anbragt inden i legemet (154) til at gå i indgreb med stemplet (164) for at muliggøre distal forskydning af stemplet (164) og i det væsentlige forhindre proksimal forskydning af stemplet (164); og - aktiveringsmidler (158) til aktivering af den medicinske indretning, hvilke aktiveringsmidler (158) har indgrebsmidler (178) til indgreb med stemplet (164) for at tillade proksimal forskydning af aktiveringsmidlerne (158) i forhold til stemplet (164) og i det væsentlige forhindre distal forskydning af aktiveringsmidlerne (158) i forhold til stemplet (164); hvor en eller flere af skraldetænderne (168) ved en proximal forskydning af aktiveringsmidlerne (158) i forhold til legemet (154) til en klartilstand passerer forbi indgrebsmidlerne (178) for at forskyde aktiveringsmidlerne (158) proximalt i forhold til stemplet (164); hvorved aktiveringsmidlerne (158) ved en distal forskydning af aktiveringsmidlerne (158) i forhold til legemet (154) fra klartilstanden går i indgreb med en eller flere af skraldetænderne (168) for at forskyde stemplet (164) distalt i forhold til indexeren (176) for at forskyde proppen distalt for at dispensere et medikament fra den medicinske injektor (152), og hvor stemplet (164) er drejeligt i forhold til legemet (154) for selektivt at gå i indgreb og frigøre skraldetænder (168) der er i indgreb med indexeren (176) og aktiveringsmidlerne (158); hvor stemplet (164) omfatter et antal sider hver med et antal adskilte skraldetænder (168) der er anbragt langs længden deraf; hvor mindst to af siderne har forskellig afstand mellem skraldetænderne (168); og hvor stemplet (164) er roterbart i forhold til legemet (154) for at vælge en side med en ønsket afstand mellem skraldetænderne til at gå i indgreb med indexeren (176) og aktiveringsmidlerne (158).
2. Medicinsk injektor ifølge krav 1, hvor stemplet omfatter mindst en flad side, der kan rettes på linje med indexeren og aktiveringsmidlerne, for at frigøre skraldetænderne fra indexeren og aktiveringsmidlerne.
