Description
Den foreliggende oppfinnelse vedrører et koplingselement
til frembringelse av tettsluttende, steril forbindelse med et annet koplingselement,- av den i den innledende del av krav 1 angitte type.
Fra US-patentskrift ..... (amerikansk patentsøknad
843.608) er det kjent et koplingselement som er innrettet til å frembringe en fortrinnsvis steril forbindelse mellom endene på rør eller ledninger, f.eks. ledninger som står i forbindelse med blodposer. Etter en forsegling er det følgelig garantert en steril forbindelse, og porsjoner av f.eks. blod, blodkom-ponenter eller andre medisinske stoffer, kan uttas fra en første beholder og anbringes i en annen beholder på steril måte, etter at forbindelsen er opprettet og en forseglet sammenkopling er frembrakt ved å utsette deler av koplingsorganet for strålingsenergi, slik som beskrevet i ovennevnte patentskrift.
Formålet med den foreliggende oppfinnelse er å oppnå forbedringer med henblikk på en økt bekvemmelighet og pålite-lighet i forbindelse med fremstilling og bruk.
Koplingsorganet ifølge oppfinnelsen er kjennetegnet ved
det som er angitt i karakteristikken i krav 1.
Den ytre ende av ledningsorganet, som vanligvis er anbrakt inne i det fleksible rør har en lukket endevegg med en del som rager utad fra den lukkete endevegg. Manuell bøyning av den utadragende del kan følgelig frembringe brudd i endeveggen og derved muliggjøre en åpning av ledningens ytre ende.
Oppfinnelsen vil bli nærmere forklart i det etterfølgende under henvisning til de medfølgende tegninger, hvori: Fig. 1 viser et sideriss av to koplingselementer før disse sammenføyes til et forseglet koplingsorgan. Fig. 2 viser et'^ertik'a'lt snitt^g.jtennom et koplingsorgan fremstilt av de separate koplingselementer i fig. 1. Fig. 3 viser et langsgående snitt gjennom et koplingselement i fig. 2. Fig. 4 viser et enderiss av et koplingselement i fig. 1. Fig. 5 viser et planriss av et koplingselement i fig. 1, sett ovenfra.
Fig. 6 viser et enderiss av koplingsorganet i fig. 2.
Fig. 7 viser et -:pjilifanrrs's av! koplrngsorganet i fig. 2.
Fig. 8 viser et sideriss, delvis i snitt, av to koplingselementer ifølge en annen utførelsesform av oppfinnelsen, før disse sammenføyes til et forseglet koplingsorgan.
Fig. 9 viser et planriss av et av koplingselementene i
fig. 8, sett ovenfra.
Fig. 10 viser et utsnitt av et vertikalt snitt gjennom
et koplingsorgan fremstilt av de sammenføyete koplingselementef i fig. 8.
Fig. 11 viser et langsgående snitt gjennom et av de i
fig. 10 viste koplingselementer.
Fig. 12 viser et sideriss, med visse deler utelatt, av
de sammenføyete koplingselementer i fig. 10.
Fig. 13 viser et planriss av de sammenføyete koplingselementer i fig. 10.
Det henvises til fig. 1-5 som viser en første utførelses-form av et koplingsorgan 10 som er fremstilt av koplingselementer 12, 14. Hvert av de to koplingselementer 12, 14 inneholder et hult transparent hus 16 hvis hule indre 20 kan forsegles fra omgivelsene.
En del av veggen i hvert hus omfatter en opak veggdel 22 som atskiller husets hule indre 20 fra omgivelsene. Hver opak veggdel er forseglet til den resterende del av det tilhørende transparente hus langs veggdelens 22 omkrets.
Hvert koplingselements 12, 14 hus 16 er innrettet til å sammenføyes med huset på det tilsvarende koplingselement med de respektive opake veggdeler 22 anbrakt i flatekontakt med hverandre slik som vist i fig. 2 og med veggdelene holdt i tettsluttende og fastholdt tilstand. Ved å utsette de således sammen-føyete hus for strålingsenergi på tilsvarende måte som beskrevet i ovennevnte US-patentskrift kan veggdelene som er i berøring med hverandre følgelig smelte sammen og danne en gjennomgående åpning.
De opake veggdeler 22 kan fortrinnsvis være fremstilt av
et organisk, termoplastisk materiale, fortrinnsvis et materiale med en høy smelte- eller mykningstemperatur, slik at enhver form for bakterier som oppholder seg på de opake veggdelers utvendig.e flater, blir drept når de utsettes for. den opake veggdels smelte- eller mykningstemperatur, og dessuten blir
slike bakterier innfanget i den smeltede masse. Spesielt kan
den opake veggdel 22 være fremstilt av et polykarbonatmateriale, såsom "Lexan", eller av andre termoplastiske materialer, fortrinnsvis med høyt smeltepunkt.
Den termoplastiske, opake veggdel 22 inneholder vanligvis
et fyllstoff,, såsom pulverisert trekull, aktiv kull eller kar-bonblack, for å gjøre veggdelen opak, men andreønskelige fyll-stoffer som kan absorbere den type strålingsenergi som skal benyttes, kan anvendes som erstatning for karbon.
De viste hus 16 er fremstilt av et transparent, høyt-
smeltende plastmateriale, såsom Lexan.
Strålingsenergien kan tilføres til systemet i form av synlig eller klart strålende, infrarød, ultrafiolett eller radiofrekvent energi etter ønske. Uttrykket "opak" innebærer at de opake veggdeler er innrettet til å absorbere en forholds-vis høy prosentandel av den aktuelle strålingsenergi som veggdelene utsettes for. Uttrykket "transparent" innebærer at en mindre prosentandel av den tilførte strålingsenergi absorberes. Fokusert infrarød strålingsenergi er særlig hensiktsmessig å anvende. Dersom det erønskelig kan laserstråler også anvendes for frembringelse av strålingsenergien.
De opake veggdeler 22 kan være forspent ved uniaksial
eller biaksial orientering, eller med radiale spenningsmønstre for å fremme dannelsen av en midtre åpning når de opake veggdeler smeltes sammen. Spenningsfrie veggdeler kan også anvendes, idet dannelsen av den midtre åpning foregår ved kohesjon under den varmemyknende bestrålingsoperasjon.
Hvert av koplingselementene 14, 16 er utstyrt med inn-retninger til fastholdelse av det annet kpplingselement. Disse fastholdelsesinnretninger omfatter to motstående gripearmer 24, som er anbrakt ved en første ende 26 av huset 16 og som avgrenser et spor 28 til fastholdelse av en flens, som er anbrakt i dette spor.
To motstående flenser 30 er tilsvarende anbrakt ved husets 16 annen ende 32. Hver av flensene 30 og de av gripearmene 24 dannete spor 28 er parallelle med den opake veggdel 22. Sporenes 28 bredde er dimensjonert slik at den er minst like stor som flensenes 30 bredde, slik at flensene 30 på det motstående koplingselement 12 -eller 14 kan passe inn i sporene i gripearmene 24, mens flensene 30 på det første koplingselement kan passe inn i sporene i gripearmene 24 på det motstående koplingselement. Koplingselementene kan således holdes tettsluttende sammen til et koplingsorgan som vist i fig. 2 og med de opake veggdeler 22 i anlegg mot hverandre.
De respektive koplingselementer sammenføyes ved at de skyves sammen i en retning som er parallell med planet for de opake vegger 22. Følgelig vil tilfeldige krefter, som forsøker å trekke koplingselementene fra hverandre, ikke kunne frembringe noen som helst atskillelse, ..idet den eneste mulighet for en innbyrdes bevegelse av elementene ligger i planet for sporene 28 og flensene 30.
Egnete fortanninger kan være anordnet for å bringe koplingselementene 12, 14 til å lukke sammen ved sneppertvirkning for å hindre at koplingselementene atskilles til separate komponenter etter at de er blitt sammenføyet.
Etter sammenføyningen kan koplingselementene bestråles med fokusert infrarød stråling eller liknende i et ønsket tids-rom. Når det f.eks. anvendes to motstående 150 watt Sylvania-lamper med elliptisk reflektor (modell DJL), kan det fokuserte infrarøde lys tilføres i ca. 5 sekunder for effektivt å danne en åpning gjennom de to opaké vegger 22 og samtidig bringe disse til å smelte sammen rundt åpningen for å frembringe en forseglet strømningsbane mellom det hule indre 20 i de respektive koplingselementer 12, 14. Dersom det er ønskelig kan lampen drives med mindre enn 150 watt ved bruk av en lavere spenning for å redusere strålingsintensiteten.
Hvert koplingselement er også utstyrt med en ledning 34 som kan være utformet i ett med huset 16. I den viste utførel-sesform har ledningen 34 en akse som løper langs planet for den fastgjorte, opake veggdel 22.
Ledningen 34 anbringes fortrinnsvis tettsluttende i et fleksibelt rør 36, som på sin side kan stå i forbindelse med
en forseglet beholder 38, såsom en blodpose, en beholder for parenteral oppløsning eller liknende. Når koplingselementene
12, 14 er sammenføyet og bestrålt, kan det følgelig åpnes en steril forbindelse mellom to beholdere 38 med henblikk på over-føring av fluider mellom beholderne.
Det henvises nå til fig. 8-13 som viser en annen utførel-sesform av oppfinnelsen.
Fig. 8-13 viser to koplingselementer 60, 62 hvilke, på tilsvarende måte som ovenfor, omfatter et transparent hus 64 samt en opak vegg 66, som ved sin omkrets er forseglet til det transparente hus 64 på en måte som svarer til den ovenfor beskrevne utførelsesform.
Hvert koplingselement bærer holdeinnretninger for å holde husene 64 sammen. Holdeinnretningene omfatter to motstående gripearmer 68 ved en første ende 70 av huset, og disse armer avgrenser et spor 72 til opptakelse av en flens 74, som svarer til flensene 30 i den ovenfor beskrevne utførelsesform, på
det koplingselement som det skal dannes forbindelse med.
I denne utførelsesform er flensene 74 anbrakt ved hvert hus' 64 annen ende 76, og flensene 74 er innrettet til å kunne skyves inn i og holdes fast i et spor 72 som er avgrenset av gripearmene på et annet koplingselement, med henblikk på å låse de to koplingselementer sammen med de respektive opake vegger 66 liggende mot hverandre som vist i fig. 10.
Fortanninger 78, 80 er anordnet slik at de respektive koplingselementer 60, 62 etter sammenskyvingen bare med vanske-lighet kan trekkes fra hverandre igjen ved alminnelig bruk, hvor koplingselementene for å sikre sterilitet er beregnet til å skulle holdes permanent sammen gjennom deres bruks-periode etter sammenføyningen.
I ett med hvert koplingselement 60, 62 er det utformet en ledning 84 hvis akse i den aktuelle utførelsesform danner en spiss vinkel med planet for den tilhørende opake veggdel 66. Som vist har ledningens 84 ytre ende en lukket endevegg 86 med et tynnere, skjørt område 88, som kan være ringformet. En fremspringende del 90 løper, utad fra den lukkete endevegg, slik at en manuell bøyning av den utadragende del 90 kan frembringe brudd i endeveggen 86 og derved muliggjøre åpning av ledningens 84 ytre ende.
Som i den første utførelsesform kan hver ledning 84
være innsatt tettsluttende i et fleksibelt rør 36a, som står i forbindelse med en forseglet beholder 38, såsom en blodpose.
Følgelig muliggjør en manuell manipulering av det fleksible rør.36a og av den fremspringende del 90 at det fremkalles brudd i enden 86 av hver ledning 84 for derved å åpne koplingselementene 60, 62, etter at disse er sammenføyet med hverandre til et koplingsorgan som vist i fig. 10.
Når begge koplingselementer har skjøre, forseglete ender 86 på deres respektive ledninger 84, er det ofte hensiktsmessig å åpne den ene av disse før bestrålingsoperasjonen.
I så fall vil luft som befinner seg i det forseglete kammer 94 inne i huset 64 og i ledningen 84 utvide seg under opp-varmingen og derved bevirke en trykkforskjell tvers over de opake vegger 66 under bestrålingstrinnet. Dette vil på
sin side medvirke til revning av de opake vegger 66 når disse blir svakere og smelter, til dannelse av en fortrinnsvis steril og forseglet forbindelse mellom de to koplingselementer 60, 62.
Dersom det er ønskelig er det bare nødvendig at det ene koplingselement har forseglete endevegger 86 med en utadragende del 90.F.eks. kan en tom blodpose være uten forseglet endevegg 86 og utadragende del 90, mens en blodpose som er bestemt til å oppta blod fra en giver, kan ha en slik forseglet endevegg for å hindre at blod passerer frem til den opake vegg 66 under lagring.
Den utadragende del 90 kan være avsluttet av et diametralt spor 92. Etter avbryting kan den med spor utformete ende av den utadragende, langstrakte del 90 trykkes innad i en inn-snevret del 94 på røret 36a for å holde delen 90 borte fra den åpnete ende 86. Dette hindrer tilstopping av strømnings-passasjen. I dette tilfelle tillater sporet 92 strømning gjennom den innsnevrete del 94, mens delen 90 blir holdt fast i denne.
