Claims (6)

1. Kateterpunkturinstrument (2) omfattende et lukket udformet røragtigt hus (3) i én del med et aflangt husafsnit, som går over i et forlængelsesafsnit til føring af den punkturnål (9), som med sin spids stikker ud fra det lange husafsnit på forsiden, med blodopsamlingsbeholder (7), positionsstop og spærreelement, og hvorfra der i en vinkel forgrener sig et forgreningsafsnit (5), via hvilket et kateter (8) efter udført punktur og tilbageføring af punkturnålen (9) til bag forgreningsstedet på forgreningsafsnittet (5) kan skubbes ind i det aflange husafsnit, idet der langs med forgreningsafsnittet (5) og frem til spidsen af det aflange husafsnit forløber i det mindste et brudsted (15), ved hjælp af hvilket det røragtige hus (3) på kateterpunkturinstrumentet (2), efter at kateteret (8) er skubbet igennem, kan brækkes af for at fjerne huset (3) fra kateteret (8), idet spærreelementet fikserer punkturnålen (9), når denne er ført tilbage, over forgreningsstedet på forgreningsafsnittet (5), kendetegnet ved, at spærreelementet er udformet som ekspansionslegeme (17) i det forreste afsnit på punkturnålen, hvis fangarme (10) ved tilbagetrækning af punkturnålen (9) ud over forgreningsafsnittet (5) ekspanderer til et afsætningstrin (16) i det bageste område (4) på det røragtige hus (3) og således fastholder punkturnålen.
2. Kateterpunkturinstrument ifølge krav 1, kendetegnet ved, at der på huset (3) er placeret i det mindste en holder (1), som fikserer kateteret (8), frem til dette er skubbet ind i huset (3), aftageligt i forgreningsafsnittet (5).
3. Kateterpunkturinstrument ifølge krav 1 eller 2, kendetegnet ved, at spidsen af det aflange husafsnit, hvorfra punkturnålen (9) stikker ud til punkturen, er formet spidsaffaset.
4. Kateterpunkturinstrument ifølge et af de foregående krav, kendetegnet ved, at det i det mindste ene brudsted (15) er forsynet med en herpå placeret afrivningsanordning (12).
5. Kateterpunkturinstrument ifølge krav 4, kendetegnet ved, at afrivningsanordningen (12) på brudstedet (15) er udformet som i det mindste en gribeflade til bedre trækkraftindledning i det i det mindste ene brudsted (15).
6. Kateterpunkturinstrument ifølge et af de foregående krav, kendetegnet ved, at to parallelt forløbende brudsteder (15) strækker sig langs med forgreningsafsnittet (5) frem til spidsen af huset (3) , idet deres indbyrdes afstand definerer bredden af en åbningsstrimmel (13), som kan fjernes fra huset (3), idet denne bredde svarer til bredden på det kateter (8), som skal anlægges.
