Claims (11)

1. Autoinjektor (1), der omfatter: en sprøjtebærer (7), der er indrettet til at fastholde en sprøjte (3); et stempel (9), der er indrettet til at forskyde en prop (6) i sprøjten (3); en feedback-komponent (28), der kan fastholdes i en første position og er påvirket mod en anden position, hvor en tap (28.4) er disponeret på feedback-komponenten (28); og en udvendig komponent (12, 13) med et hul (13.7), hvor feedback-komponenten (28) bevæges fra den første position til den anden position, når stemplet (9) under forskydning af proppen (6) når en forudbestemt position, og hvor tappen (28.4) trænger ind i hullet (13.7), når feedbackkomponenten (28) er i den anden position, hvor en drivfjeder (8) er anbragt i bæreren (7), som er distalt fastgjort i bæreren (7) og proksimalt hviler mod en trykside (11) på stemplet (9), hvor en feedback-fjeder (29) er indrettet til at påvirke feedback-komponenten (28) i en distal retning (D) i forhold til stemplet (9) ved proksimalt at hvile mod stemplet (9) og distalt mod feedback-komponenten (28), der er kendetegnet ved, at feedback-fjederen (29) er forskellig fra drivfjederen (8).
2. Autoinjektor (1) ifølge krav 1, der yderligere omfatter: en frigørelsesmekanisme (31), der er indrettet til at frigøre feedback-komponenten (28), når stemplet når den forudbestemte position.
3. Autoinjektor (1) ifølge et af kravene 1 eller 2, hvor den udvendige komponent (12, 13) omfatter mindst en del af et hylster (12), en udløserknap (13) og/eller en muffeudløser (12) .
4. Autoinjektor (1) ifølge et af ovennævnte krav, hvor tappen (28.4) flugter med en ydre overflade af den udvendige komponent (12, 13) eller stikker frem fra den ydre overflade af den udvendige komponent (12, 13), når feedback-komponenten (28) er i den anden position.
5. Autoinjektor (1) ifølge et af ovennævnte krav, hvor et dæksel (34) er anbragt på den udvendige komponent (12, 13) over hullet (13.7), hvor dækslet (34) er indrettet til mindst delvist at blive skilt fra den udvendige komponent (12, 13), når det påvirkes af tappen (28.4) .
6. Autoinjektor (1) ifølge krav 5, hvor dækslet (34) er hængselforbundet til den udvendige komponent (12, 13).
7. Autoinjektor (1) ifølge krav 5, hvor dækslet (34) er en film.
8. Autoinjektor (1) ifølge et af ovennævnte krav, hvor mindst én elastisk rampeholdig klinke (17.1) er anbragt på stemplet (9) eller på en distal stempelmuffe (17) deraf, der kan gå i indgreb med en rampeholdig overflade (28.5) på feedback-komponenten (28) på en måde til fastholdelse af feedback-komponenten (28) i den første position, hvor et vægstykke (7.22) af sprøjtebæreren (7) eller hylsteret (12) er indrettet til understøtning udad af den elastiske rampeholdige klinke (17.1) til forhindring af, at den afbøjer udad, hvor den elastiske rampeholdige klinke (17.1) er indrettet til at blive translateret ud af vægstykket (7.22), når stemplet (9) når den forudbestemte position, til derved muliggørelse af afbøjning udad af den elastiske rampeholdige klinke (17.1) som følge af dens rampeindgreb med feedback-komponenten (28) og som følge af, at feedback-komponenten (28) påvirkes mod den anden position, til derved frigørelse af feedback-komponenten (28) .
9. Autoinjektor (1) ifølge et af ovennævnte krav, hvor feedback-komponenten (28) er indrettet til at påvirke den udvendige komponent (12, 13), når den når den anden position, og påvirkningen frembringer et hørligt feedback.
10. Autoinjektor (1) ifølge et af ovennævnte krav, hvor den forudbestemte position af stemplet (9) er en position, hvor proppen (6) har mindst næsten nået bunden af sprøjten (3).
