Claims (11)

1. Anordning til medikament fremføring (1), der omfatter: et hus (10, 30, 32); en teleskopisk stempelstangsindretning (18, 35, 40) til at drive en spuns (20) i en medikamentbeholder (9); og en drivmekanisme (15, 16) til den teleskopiske stempelstangsindretning; hvilken teleskopiske stempelstangsindretning omfatter et pressestempel (35) til at drive spunsen (20), en stopknast (40) til muliggørelse af overvejende aksial bevægelse mellem pressestemplet (35) og huset (30); og et indgangsdrev (18), der er teleskopisk koblet til pressestemplet (35) og understøttet til rotationel og aksial bevægelse i forhold til huset (30); hvilken drivmekanisme omfatter et overføringsdrev (16), der er operativt til rotation af indgangsdrevet (18), hvorved indgangsdrevet bevæges aksialt i forhold til huset (30), når indgangsdrevet bevæges teleskopisk i forhold til pressestemplet (35), og hvor pressestemplet er forsynet med et ydre gevind (37), der går i indgreb med et indre gevind (43) på indgangsdrevet (18), således at rotation af indgangsdrevet teleskopisk trækker pressestemplet tilbage eller frem i forhold til indgangsdrevet; der er kendetegnet ved, at: indgangsdrevet (18) er forsynet med et drivtandhjul i dets ende modsat det indre gevind (43) til tilkobling med et aksialt udgående tandhjul på overføringsdrevet (16), således at når indgangsdrevet roteres ved hjælp af overføringsdrevet, kan drivtandhjulet glide langs det aksialt udgående tandhjul i forhold til huset (30).
2. Anordning til medikamentfremføring (1) ifølge krav 1, hvor stofknasten (40) åbner mulighed for en forudbestemt mængde rotationsbevægelse.
3. Anordning til medikamentfremføring (1) ifølge krav 1 eller krav 2, hvor indgangsdrevet (18) er forsynet med et ydre gevind (33), der går i indgreb med og passerer gennem en åbning med et tilsvarende gevind (41) i huset (30, 32).
4. Anordning til medikamentfremføring (1) ifølge krav 3, hvor stopknasten (40) omfatter en aflang del, der ikke-rotationelt strækker sig ind i (43) en ende af pressestemplet (35) modsat den ende (36) deraf, der driver medikamentpatronstemplet.
5. Anordning til medikamentfremføring (1) ifølge krav 4, hvor stopknasten (40) strækker sig gennem indgangsdrevet (18), således at enden af stopknasten (40) væk fra pressestemplet (35) strækker sig ind i huset (30), så den ligger i det væsentlige tilgrænsende til det aksialt udgående tandhjul på overføringsdrevet (16).
6. Anordning til medikamentfremføring (1) ifølge krav 5, hvor enden af stopknasten (40) er forsynet med en tap (46) eller et fremspring, der strækker sig over drivtandhjulet på indgangsdrevet (18) og ind i en tilsvarende planforsænkning eller styredel (47) på eller i huset (30, 32).
7. Anordning til medikamentfremføring (1) ifølge krav 6, hvor den tilsvarende planforsænkning eller styredel (47) er disponeret parallelt med det aksialt udgående tandhjul på overføringsdrevet (16), således at når indgangsdrevet (18) roteres og bevæger sig gennem åbningen med gevind (41), bevæger stopknasten (40) sig aksialt parallelt i det mindste i en del af længden af det aksialt udgående tandhjul.
8. Anordning til medikamentfremføring (1) ifølge krav 6, hvor den tilsvarende planforsænkning eller styredel (47) er disponeret ikke-parallelt med det aksialt udgående tandhjul på overføringsdrevet (16), således at når indgangsdrevet (18) roteres og bevæger sig gennem åbningen med gevind (41), bevæger stopknasten sig aksialt og rotationelt efter skævheden på planforsænkningen eller styredelen.
9. Anordning til medikamentfremføring (1) ifølge et hvilket som helst af ovennævnte krav, hvor drivmekanismen omfatter en anordning (51, 52, 53) til reducering af støj og/eller reducering af tolerancer i drivmekanismen (15, 16).
10. Anordning til medikamentfremføring (1) ifølge et hvilket som helst af ovennævnte krav, hvor huset (10) inkluderer en holder (12) til en brugerudskiftelig medikamentpatron (9).
11. Autoinjektor, der inkluderer en anordning til medikamentfremføring (1) ifølge et hvilket som helst af ovennævnte krav.
