Claims (6)

1. Engangsinjektionsindretning til afgivelse af en dosis lægemiddel, omfattende et hovedsageligt aflangt hus (10), en beholder (14) indeholdende lægemiddel til injektion gennem en kanyle (16), trykmidler (34, 40), der virker på beholderen og efter aktivering er i stand til at bevæge beholderen og kanylen til penetrering og efterfølgende udstødning af lægemiddel gennem kanylen, aktiveringsorganer (26) indrettet til at aktivere trykmidlerne, kendetegnet ved, at aktiveringsorganerne omfatter et kanyleskjold (12), der er indrettet til at kunne glide i forhold til huset, et sammenfoldeligt holdeorgan (58), der er forbundet til den indre ende af kanyleskjoldet, hvor det sammenfoldelige holdeorgan efter flytning af kanyleskjoldet folder sammen, når et bestemt tryk påføres med kanyleskjoldet, og hvor yderligere bevægelse af kanyleskjoldet aktiverer aktiveringsorganerne, som dernæst frigiver trykmidlerne og indleder en lægemiddelinjektion, og hvor det sammenfoldelige holdeorgan omfatter et generelt rørformet organ (70) med flere længderettede udskæringer (72), som danner flere aflange strimler (74) mellem udskæringerne, og hvor de aflange strimler har en tværsnitsform, der øger stabiliteten af de aflange strimler.
2. Engangsinjektionsindretning ifølge krav 1, hvor det sammenfoldelige holdeorgan omfatter mindst én aflang del anbragt hovedsagelig i injektionsindretningens længderetning.
3. Engangsinjektionsindretning ifølge krav 2, hvor den aflange del er fremstillet af et materiale, der vender tilbage til sin oprindelige form, når trykket fjernes.
4. Engangsinjektionsindretning ifølge krav 2 eller 3, hvor den aflange del omfatter et metalbånd.
5. Engangsinjektionsindretning ifølge krav 2 eller 3, hvor den aflange del omfatter et plastbånd.
6. Engangsinjektionsindretning ifølge ethvert af de foregående krav, hvor huset er indrettet med et mellemrum (64) til optagelse af dele af det sammenfoldelige organ, når det er sammenfoldet.
