Description

PATENTKRAV 1. Sikkerhedsinjektionssprøjte (1) bestående af: en sprøjtecylinder (2) udformet som et hult cylinderlegeme med begge ender åbne, hvor den ene ende er udformet som en dyse (21), og en anden ende som en fingerflange (22); et sprøjtestempel (3), som er teleskopisk anbragt inde i sprøjtecylinderen (2), og hvis ene ende er udstyret med et gummistempel (31) til dannelse af en tæt kontakt med og glidning indvendigt i sprøjtecylinderen (3), og hvis anden ende er udformet som en tommelfinger-hvileflade (32); et nålesæt (4), som omfatter en nålkanyle (41), et nålefæste (42) til forankring af nålkanylen (41), og en adapter (43) til fastholdelse af nålefæstet (42), hvor nålesættet (4) er teleskopisk anbragt inde i dysen (21) på sprøjtecylinderen (3) med nålkanylen blottet mod det ydre af sprøjtecylinderen (3); og et nålehylster (5) anbragt uden for dysen på sprøjtecylinderen (3) til afskærmning af nålkanylen (41) i nålesættet (4); hvor nålefæstet (42) har et udvendigt gevind til indgreb i et indvendigt gevind i adapteren (43); adapteren har en basis (46) med en langs omkredsen rundtgående rille (47) til en gummitætning (48), hvor gummitætningen (48) danner en tæt kontakt mellem basis (46) og dysen (21); basis (46) på adapteren (43) er udformet med et konisk hul (49) med e n mindskende diameter ved bunden heraf, hvor det koniske hul (49) er omsluttet af et antal klipsmidler (50), som er symmetrisk anbragt med lige radiale intervaller, hvor klipsmidlerne (50) er dannet med vinkeldele, som hælder indad med henblik på at definere profilen af det koniske hul (49), og et fremspring (40) er tildannet et passende sted på basis (46) tæt ved det koniske hul (49); og gummistemplet (31) på sprøjtestemplet (3) er udstyret med en konisk stav (33), som kan optages i det koniske hul (49) i adapteren (43) med henblik på indbyrdes indgreb. 2. Sikkerhedsinjektionssprøjte ifølge krav 1, hvor det koniske hul (49) e r anbragt i centrum af basis (46) på adapteren (43) med henblik på at ligge på linie med nålkanylen (41) og nålefæstet (42). 3. Sikkerhedsinjektionssprøjte ifølge krav 1, hvor det koniske hul (49) e r anbragt i centrum af basis (46) på adapteren (43), og nålkanylen (41) samt nå lefæstet (42) ligger på linie med et gennemgående hul (51) i adapteren (43) med henblik på dannelse af en sidefluidumrute i forhold til det koniske hul (49). 4. Sikkerhedsinjektionssprøjte ifølge krav 1, hvor det koniske hul (49) er omgivet af tre symmetrisk anbragte klipsmidler (50). 5. Sikkerhedsinjektionssprøjte ifølge krav 1, hvor det koniske hul (49) er omgivet af fire symmetrisk anbragte klipsmidler (50). 6. Sikkerhedsinjektionssprøjte ifølge krav 1, hvor det koniske hul (49) er omgivet af seks symmetrisk anbragte klipsmidler (50).
