Claims (7)

1. Injektionsanordning (1) til fremføring af et medikament til en patient, hvilken injektionsanordning omfatter: et hus; en stempelstang til at drive en spuns i en medikamentbeholder (9); en drivmekanisme, der indbefatter en motor (13), til tilvejebringelse af et udgangsdrev til stempelstangen til fremføring af en dosis af medikamentet; og et kontrolmiddel til at kontrollere funktionen af anordningen; hvor kontrolmidlet omfatter: en drevsignalgenerator til generering af et indgangsdrevsignal for motoren; en koder til generering et koderudgangssignal, der viser udgangsdrevet for motoren; og et middel til at variere den operationelle kontrol af anordningen afhængig af en sammenligning mellem indgangsdrevsignalet og koderudgangssignalet, hvor koderudgangssignalet er et pulseret signal med et karakteristisk tidsforløb, der svarer til udgangsdrevet for motoren, hvor en sammenligning mellem tælletal for den pulserede koderudgang og tælletal for stepperimpulser indikerer motorstop eller motorslip, hvor motoren stoppes forsætligt mod et forudbestemt referencepunkt, når mængden af slip overstiger en forudbestemt grænseværdi, der er kendetegnet ved, at: kontrolmidlet beregner underskuddet i det administrerede medikament og udfører administration af denne dosis.
2. Injektionsanordning ifølge krav 1, hvor indgangsdrevsignalet omfatter stepperimpulser til at drive motoren.
3. Injektionsanordning ifølge krav 1 eller krav 2, hvor et antal referencepunkter er indbefattet i anordningen, hvor hvert referencepunkt indikerer forskellige operationelle aspekter af anordningen.
4. Injektionsanordning ifølge krav 3, hvor referencepunkterne indbefatter et eller flere af: bagstopposition; fremført dosis; dørposition; drevposition; og nulstillingstærskel.
5. Injektionsanordning ifølge kravene 2 til 4, hvor referencepunkterne vedrører indgangsdrevsignalet, således at forskellige referencepunkter svarer til respektive tælletal for stepperimpulser med henvisning til et anordningsdatum.
6. Injektionsanordning ifølge krav 1, hvor kontrolmidlet i tilfælde af påvisning af motorslip eller motorstop er i stand til at bestemme mængden af slip i forhold til et af referencepunkterne, hvorpå det varierende middel justerer den operationelle kontrol af anordningen ifølge forudbestemte kriterier.
7. Autoinjektionsanordning ifølge et hvilket som helst af ovennævnte krav.
