Abstract

Selvaspirerende hypodermisk patron (1) som Inneholder et injlserbart fluid omfatter et hovedsakelig sylind- risk løp (3) med en vegg, og en plunger (10,50,44) frem og tilbake bevegelig i løpet (3) for å aspirere patronen (1) og for å drive ut det injiserbare fluid fra denne. Plungeren (10,50,44) omfatter en hund- ringkomponent (10) med et vertikalt orientert sylind- risk hull (36), med et sylindrisk flatt bunnparti (20), et sylindrisk flatt toppart! (30) beliggende i avstand fra det sylindriske flate bunnparti (20), og et sldepartl (40) som forbinder det sylindriske flate bunnparti (20), og et sideparti (40) som forbinder det sylindriske bunn- og toppart! (20,30) og integrert med disse, hvilket sideparti (40) har en helningsgrad l forhold til et horisontalplan fra omlag 1° til omlag 89°; en soppformet han-komponent (50) med et sylindrisk plungerskaft (52) glidbart plassert i hun-ringkompo- nenten (10), og et konisk formet hode (56) i en ende av skaftet (52) og integrert med dette og har en helnings- grad i forhold til horisontalplanet fra omlag l* til omlag 89°; og en elastomer diafragma-kappe (44) med et sylindrisk bunnparti (42) og et hovedsakelig konisk formet sideparti (48) integrert med dette som dekker han- og hunkomponentene (50,10), hvilket sylindriske bunnparti (42) er tilpasset til å danne en glldbar tetning mellom hun-ringkomponenten (10) og veggen av det sylindriske løp (3), og det konisk formede sideparti (48) er tilpasset til å tjene som en diafragma hvorved det ved alternerende utøvelse av trykk på plungerskaftet (52) og frigjøring av dette reduserer deformasjonen av diafragmaen det øvre rom i det sylindriske løp (3) som dermed driver ut gass i dette rom og ved frigjøring av trykket returnerer diafragmaen til sin opprinnelige form som medfører aspirasjon.
