Description

Foreliggende oppfinnelse angår et lukke for beholdere for eventuelt infisert væske, særlig for beholdere til bruk ved blodprøvetaking og -undersøkelser. The present invention relates to a closure for containers for potentially infected liquid, in particular for containers for use in blood sampling and examinations.

Innen helsetjenesten er det i den senere tid stillet stadig sterkere krav til de hygieniske forhold i forbindelse med blodprøvetaking og blodundersøkelser, både rutinemessige undersøkelser som et ledd i den daglige helsetjeneste, slik som blodtyping, blodsenkningsbestemmelser og lignende, men kanskje i ennå større grad i forbindelse med blodprøvetaking i tilfeller der det foreligger mistanke om AIDS-infeksjon eller infeksjon av den dødelige virus "S-agent". Within the health service, there have recently been increasingly strong demands on the hygienic conditions in connection with blood sampling and blood tests, both routine tests as part of the daily health service, such as blood typing, blood lowering regulations and the like, but perhaps to an even greater extent in connection with blood sampling in cases where there is suspicion of AIDS infection or infection with the deadly virus "S-agent".

I en meget stor del av arbeidet i forbindelse med slik blodprøvetaking og slike blodundersøkelser benyttes det såkalte "vacuutainer", dvs. plast- eller glassrør som på forhånd er satt under vakuum for å lette innsugning av blod og i hvilke det f.eks. på forhånd kan være anbragt antikoa-guleringsmidler, men i hvilke fremfor alt blodet f.eks. underkastes sentrifugering for å skille den i serum og røde blodlegemer eller eventuelt blodkoagel. In a very large part of the work in connection with such blood sampling and such blood examinations, the so-called "vacuutainer" is used, i.e. plastic or glass tubes which have been placed under vacuum in advance to facilitate the suction of blood and in which e.g. anticoagulants may be placed in advance, but in which above all the blood e.g. subjected to centrifugation to separate it into serum and red blood cells or possibly blood clot.

Slike rør er lukket i en eller i begge ender med en elastisk propp som ved innføring av blod gjennomtrenges av en kanyle. Such tubes are closed at one or both ends with an elastic stopper which, when blood is introduced, is penetrated by a needle.

Det har til nå ikke vært til å unngå at det ved uttrekking av kanylen fra denne lukkepropp er blitt tilbake en dråpe blod på proppen, en bloddråpe som etter dagens oppfatning klart representerer en helsemessig risiko for behandlingspersonale hvis blodet skulle stamme fra en pasient med hepatitt B, en AIDS- eller S-agent-infisert pasient. Until now, it has not been possible to avoid that when the cannula is withdrawn from this stopper, a drop of blood has remained on the stopper, a drop of blood which, according to today's opinion, clearly represents a health risk for treatment staff if the blood were to come from a patient with hepatitis B , an AIDS or S agent-infected patient.

Det skal her innskytes at selv om foreliggende oppfinnelse beskrives i forbindelse med blodprøvetaking og blodunder-søkelser, vil den finne like stor anvendelse på områder der det er snakk om transport, overføring og undersøkelser av smittefarlige og/eller infiserende væsker. It should be noted here that although the present invention is described in connection with blood sampling and blood tests, it will find equal application in areas where there is a question of transport, transfer and examinations of infectious and/or infectious liquids.

Som nevnt ovenfor vil det ved uttrekking av en kanyle fra en propp som nevnt innledningsvis alltid bli tilbake en dråpe på den ytre overflate av proppen, en dråpe som kan representere en sikkerhetsrisiko. As mentioned above, when withdrawing a needle from a stopper as mentioned at the outset, a drop will always remain on the outer surface of the stopper, a drop which can represent a safety risk.

Foreliggende oppfinnelse tar sikte på å eliminere dette problem for derved å forbedre den kjente teknikk og oppfinnelsen angår i henhold til dette et lukke for beholdere til bruk i forbindelse med blodprøvetaking og -undersøkelser, omfattende to deler, i prinsipp delt loddrett på lengdeaksen til beholderen, der den ene del er utstyrt med en gjennomgående kanal og oppfinnelsen kjennetegnes ved at den er tildannet ved hjelp av en hanndel og en hunndel slik at delenes gjennomløpende kanal før kassering av delen er tettet av en i kanalen innført projeksjon. The present invention aims to eliminate this problem in order to thereby improve the known technique and the invention accordingly relates to a closure for containers for use in connection with blood sampling and examinations, comprising two parts, in principle divided vertically on the longitudinal axis of the container, where one part is equipped with a continuous channel and the invention is characterized by the fact that it is formed with the help of a male part and a female part so that the continuous channel of the parts before discarding the part is sealed by a projection introduced into the channel.

Oppfinnelsen skal beskrives nærmere under henvisning til de ledsagende tegninger som beskrives i forbindelse med prøvetaking og separering av blod og der The invention shall be described in more detail with reference to the accompanying drawings which are described in connection with sampling and separation of blood and where

fig. 1 viser situasjonen etter at en blodoverføringskanyle er trukket ut av et lukke ifølge oppfinnelsen og etter at blodet er separert i serum og røde blodlegemer eller blodkoagel, fig. 1 shows the situation after a blood transfusion cannula has been pulled out of a closure according to the invention and after the blood has been separated into serum and red blood cells or blood clot,

fig. 2 etter at en del av lukke ifølge oppfinnelsen er fig. 2 after a part of the closure according to the invention is

fjernet, removed,

fig. 3-5 viser innføring av og overføring til et fig. 3-5 show introduction of and transfer to a

transportrør av f.eks. blodserum, transport pipes of e.g. blood serum,

fig. 6 viser hvordan dette kan transporteres og avgis for fig. 6 shows how this can be transported and delivered for

ytterligere utprøving, og further testing, and

fig. 7 viser en alternativ utførelsesform av lukket ifølge fig. 7 shows an alternative embodiment of closed according to

oppfinnelsen. the invention.

Ved hjelp av en ikke-vist kanyle blir på konvensjonell måte blod innført i et rør, for eksempel en "vacuutainer" 4, idet en ikke-vist kanyle er stukket gjennom lukke 1,2 og blod Innført 1 beholderen 4. By means of a needle not shown, blood is conventionally introduced into a tube, for example a "vacuutainer" 4, a needle not shown being inserted through the closure 1,2 and blood Introduced 1 the container 4.

Kanylen er deretter trukket ut og har som antydet etterlatt seg en bloddråpe, antydet ved B. The needle is then withdrawn and, as indicated, has left behind a drop of blood, indicated at B.

Før eller etter sentr 1 fuger ing, blir den ytre del 1 med "rlslkobloddråpen" B kassert. Etter separering er blodet skilt i serum 5 og røde blodlegemer eller blodkoagel 7 med mellomliggende fibrin 6. Before or after center 1 jointing, the outer part 1 with the "rlslkoblood drop" B is discarded. After separation, the blood is separated into serum 5 and red blood cells or blood clot 7 with intermediate fibrin 6.

Som antydet på figurene er den andre del 2 av oppfinnelsens lukke i det viste tilfellet utstyrt med en gjennomløpende kanal 3 hvori det er i det viste tilfellet anordnet et filter 3'. Man kan tenke seg at det i den gjennomløpende kanal 3 også f.eks. er anordnet en tynn membran ved beholderenden av kanalen 3, dette særlig for å holde på plass filteret 3' ved sentrifugering, men også av regulære hygienesikkerhetsmessige grunner. As indicated in the figures, the second part 2 of the closure of the invention in the case shown is equipped with a continuous channel 3 in which a filter 3' is arranged in the case shown. One can imagine that in the continuous channel 3 also e.g. a thin membrane is arranged at the container end of the channel 3, this in particular to keep the filter 3' in place during centrifugation, but also for regular hygienic safety reasons.

I fig. 3 vises videre et oppsamlings- eller transportrør 8 for serum 5 eller blodlegemer 7. Røret i det viste tilfellet er i den ene ende utstyrt med en spiss 10 beregnet til innføring i den gjennomgående kanal 3 i lukket indre del 2. Man kan imidlertid tenke seg røret 8 f.eks. med en åpen ende og med en utoverragende krave, i dette tilfelle måtte man da holde det hele slik at serum 5 kan presses/renne inn i røret 8. In fig. 3 also shows a collection or transport tube 8 for serum 5 or blood cells 7. The tube in the case shown is equipped at one end with a tip 10 intended for insertion into the continuous channel 3 in the closed inner part 2. However, one can imagine the tube 8 e.g. with an open end and with a protruding collar, in this case the whole thing had to be held so that the serum 5 can be pressed/flowed into the tube 8.

Ved å presse røret 8 med lukkedelen 2 inn^i beholderen 4 blir f.eks. serum 5 presset inn i røret 8 i ønsket mengde. Røret 8 i det viste tilfellet er videre i den andre ende utstyrt med en spiss 9, fortrinnsvis anordnet med et ikke-vist filter. Videre er røret 8 fortrinnsvis av et elastisk materiale slik at den fra røret 4 overførte væske ved sammenpressing av røret 8 slik dette er antydet ved 12 i fig. 6, kan presses ut av munningen 9 som dråper 11. By pressing the tube 8 with the closing part 2 into the container 4, e.g. serum 5 pressed into the tube 8 in the desired amount. The pipe 8 in the case shown is further equipped at the other end with a tip 9, preferably arranged with a filter not shown. Furthermore, the pipe 8 is preferably made of an elastic material so that the liquid transferred from the pipe 4 when compressed by the pipe 8 as indicated by 12 in fig. 6, can be squeezed out of the mouth 9 as drops 11.

Under henvisning til fig. 3, 4 og 5 kan man tenke seg den indre del 2 av lukket ifølge oppfinnelsen utstyrt med en membran som delvis lukker den gjennomgående kanal 3, en slik anordning vil spesielt kunne finne anvendelse der det er ønskelig å trekke ut f.eks. serum ved hjelp av ytterligere en sprøyte 14 med kanyle 15 slik dette er antydet i fig. 7. With reference to fig. 3, 4 and 5, one can imagine the inner part 2 of closed according to the invention equipped with a membrane which partially closes the continuous channel 3, such a device would particularly be able to find application where it is desirable to extract e.g. serum using a further syringe 14 with needle 15 as indicated in fig. 7.

Som antydet ovenfor unngår man ved et lukke ifølge oppfinnelsen, et lukke som er delt i en ytre del 1 for kassering, og en indre del 2 som blir tilbake i beholderen og som i fig. 1 til 5 videre er brukt som et stempel, så og si en hver mulighet for at betjeningspersonalet skal komme i kontakt med eventuelt infisert blod. As indicated above, a closure according to the invention avoids a closure which is divided into an outer part 1 for disposal, and an inner part 2 which remains in the container and as in fig. 1 to 5 onwards are used as a stamp, so to speak, every opportunity for the operating staff to come into contact with potentially infected blood.

Det skal her nok en gang påpekes at oppfinnelsen ikke er begrenset til bruk i forbindelse med blodprøvetaking og blodundersøkelser, den vil kunne finne anvendelse ved en hver form for behandling av væsker der det foreligger en mulighet for infeksjonsfare. It should be pointed out here once again that the invention is not limited to use in connection with blood sampling and blood tests, it will be able to find application in any form of treatment of liquids where there is a possibility of infection.

Oppfinnelsen kan videre benyttes i forbindelse med innret-ninger for gjennomføring av senkningsbestemmelser i veneblod slik disse f.eks. er beskrevet i norsk søknad nr. 862150. I den der beskrevne innretning kan man som beskrevet i forbindelse med foreliggende oppfinnelse, også tenke seg et todelt lukke i senkningsrøret 1. The invention can also be used in connection with devices for carrying out lowering determinations in venous blood such as these, e.g. is described in Norwegian application no. 862150. In the device described there, as described in connection with the present invention, one can also imagine a two-part closure in the lowering pipe 1.

Som antydet ovenfor eliminerer man ved bruk av et lukke ifølge oppfinnelsen, særlig I forbindelse med behandling av blod, så og si en hver mulighet for at behandlingspersonalet skal komme i konakt med blodet, og dette representerer et vesentlig fremskritt i forholdt til den teknikk som til idag har vært benyttet der denne risiko slett ikke har kunnet utelukkes. As indicated above, by using a closure according to the invention, particularly in connection with the treatment of blood, virtually every possibility of the treatment staff coming into contact with the blood is eliminated, and this represents a significant advance in relation to the technique which today has been used where this risk could not be ruled out at all.
