Description

Den foreliggende oppfinnelse vedrører en rørkopling av den The present invention relates to a pipe connection of it

i den innledende del av krav 1 angitte type. in the introductory part of claim 1 specified type.

Det er kjent rørkoplinger med Luer-låsing, hvor hankoplingsdelen har en yttermuffe med innvendige gjenger for å etablere gjengeinngrep med hunkoplingsdelen som er utstyrt med utvendige gjenger eller har en radial flens. Visse rørkoplinger med Luer-låsing har vist seg å være utette, og dette kan resul-tere i luftemboli eller kan skape forurensningsproblemer. Visse kjente rørkoplinger med Luer-låsing har også vist seg å være vanskelige å anvende, idet en frikopling av hankopiingsclelen fra hunkoplingsdelen er ytterst vanskelig etter at sammen-kopling er foretatt. Tube couplings with Luer locking are known, where the male coupling part has an outer sleeve with internal threads to establish thread engagement with the female coupling part which is equipped with external threads or has a radial flange. Certain tube connections with Luer locking have proven to be leaky, and this can result in air embolism or can create contamination problems. Certain known tube connections with Luer locking have also proven to be difficult to use, since disconnecting the male coupling cell from the female connection part is extremely difficult after connection has been made.

Det er et formål med den foreliggende oppfinnelse å frembringe en rørkopling med Luer-låsing, som har en fluidumtett forbindelse. It is an object of the present invention to produce a tube connection with Luer locking, which has a fluid-tight connection.

Et annet formål med oppfinnelsen er å frembringe en rør-kopling med Luer-låsing, som muliggjør en tydelig inspeksjon av forbindelsen. Another object of the invention is to produce a tube connection with Luer locking, which enables a clear inspection of the connection.

Et ytterligere formål med oppfinnelsen er å frembringe en rørkopling med Luer-låsing hvor delene som passer til hverandre er forbelastet før låsingen. A further purpose of the invention is to produce a tube connection with Luer locking where the parts that fit together are preloaded before locking.

Det er videre et formål med oppfinnelsen å frembringe en rørkopling med Luer-låsing og som er av enkel konstruksjon og er effektiv å fremstille. It is a further object of the invention to produce a tube connection with Luer locking which is of simple construction and is efficient to manufacture.

Rørkoplingen ifølge oppfinnelsen er kjennetegnet ved det som er angitt i karakteristikken i krav 1. The pipe connection according to the invention is characterized by what is stated in the characteristic in claim 1.

Ifølge oppfinnelsen er det således frembrakt en rørkopling med Luer-låsing, som omfatter en hankoplingsdel med et rørformet legeme og som avgrenser en boring, idet dens fremre ende er innrettet til å anbringes i en hunkoplingsdel, mens dens bakre ende cr innrettet til å sammenkoples med en rørledning. Det rørformete legeme har en fremre del som støter opp til den fremre ende, og en hoveddel som er atskilt fra den fremre del av et muffeholdeorgan. En muffe har en vanligvis elastisk bakre del som kan forskyves langs hoveddelen. Muffen har også en fremre del som er utstyrt med innvendige gjenger og er innrettet til å oppta en hunkoplingsdel med utvendige gjenger eller en utvendig flens. Det rørformete legemes hoveddel har stigning utad i retning fremover. På denne måte foregår det en økende kompresjon mellom muffens bakre del og det rørformete legemes hoveddel når muffen beveges fremover. According to the invention, a pipe coupling with Luer locking has thus been produced, which comprises a male coupling part with a tubular body and which delimits a bore, its front end being adapted to be placed in a female coupling part, while its rear end cr being adapted to be connected with a pipeline. The tubular body has a front part which abuts the front end, and a main part which is separated from the front part by a sleeve holding member. A sleeve has a usually elastic rear part which can be displaced along the main part. The socket also has a front part which is provided with internal threads and is adapted to receive a female coupling part with external threads or an external flange. The main part of the tubular body slopes outwards in the forward direction. In this way, an increasing compression takes place between the rear part of the sleeve and the main part of the tubular body when the sleeve is moved forward.

I en utførelsesform av oppfinnelsen omfatter muffeholde-delen en utadragende ring som er utformet på det rørformete legeme. Den bakre del av muffen har mindre innerdiameter enn ytterdiameteren for den utadragende ring, slik at denne utadragende ring hindrer en fremadrettet bevegelse av muffens bakre del forbi et forutbestemt punkt. In one embodiment of the invention, the sleeve holding part comprises a projecting ring which is formed on the tubular body. The rear part of the sleeve has a smaller inner diameter than the outer diameter of the protruding ring, so that this protruding ring prevents a forward movement of the rear part of the sleeve past a predetermined point.

Ifølge oppfinnelsen kan muffens bakre del dessuten danne to motstående spalter for å gjøre muffens bakre del elastisk ettergivende i betydelig grad. Det rørformete legeme kan ha to utad-rettede flenser bak ved hoveddelen, slik at flensene og spaltene samvirker til å hindre innbyrdes dreining av muffen og det rør-formete legeme når flensene befinner seg i spaltene. According to the invention, the rear part of the sleeve can also form two opposite slits to make the rear part of the sleeve elastically yielding to a considerable extent. The tubular body can have two outward-facing flanges at the back of the main part, so that the flanges and the slits work together to prevent mutual rotation of the sleeve and the tubular body when the flanges are in the slits.

Oppfinnelsen vil bli nærmere beskrevet i det etterfølgende under henvisning til den medfølgende tegning, hvori:' The invention will be described in more detail below with reference to the accompanying drawing, in which:

Fig. 1 viser et perspektivriss av en rørkopling med Luer-låsing ifølge oppfinnelsen. Fig. 2 viser et snitt gjennom hankoplingsdelen i koplingen i fig. 1. Fig. 3 viser et forstørret snitt av en muffe som er anbrakt på hankoplingsdelen i fig. 1 og 2, og hvor muffens forbindelse med hunkoplingsdelen er vist. Fig. 1 shows a perspective view of a pipe connection with Luer locking according to the invention. Fig. 2 shows a section through the male coupling part in the coupling in fig. 1. Fig. 3 shows an enlarged section of a sleeve which is placed on the male connection part in fig. 1 and 2, and where the socket's connection with the female connection part is shown.

Det henvises til tegningen som viser en rørkopling med Luer-lås og omfatter en hankoplingsdel 10 og en hunkoplingsdel 12. Hunkoplingsdelen 12 er av den type hvor et hovedlegeme 14 danner en boring 16, og en flens 18 omgir boringen 16 og løper radialt utad fra hovedlegemet 14. Flensens 18 lengde er avpasset slik at flensen kan samvirke med en innvendig gjenge i en muffe 20 som er anbrakt på hankoplingsdelen 10. Et plastrør 22 er fes-tet til'hovedlegemet 14 ved anvendelse av trykk og tetning med Reference is made to the drawing which shows a pipe connection with a Luer lock and comprises a male connection part 10 and a female connection part 12. The female connection part 12 is of the type where a main body 14 forms a bore 16, and a flange 18 surrounds the bore 16 and runs radially outwards from the main body 14. The length of the flange 18 is adapted so that the flange can cooperate with an internal thread in a sleeve 20 which is placed on the male connection part 10. A plastic pipe 22 is attached to the main body 14 by applying pressure and sealing with

løsningsmiddel, slik det er velkjent på området. solvent, as is well known in the art.

Hankoplingsdelen 10 har et rørformet legeme 24 som avgrenser en boring 26 med en fremre ende 30 som er innrettet til å anbringes i boringen 16 i hunkoplingsdelen 12. Yttersiden av den fremre del 28 er dimensjonert slik at det fremkommer en stram presspasning i boringen 16. The male coupling part 10 has a tubular body 24 which delimits a bore 26 with a front end 30 which is arranged to be placed in the bore 16 in the female coupling part 12. The outer side of the front part 28 is dimensioned so that a tight press fit in the bore 16 occurs.

Det rørformete legeme 24 omfatter også en hoveddel 32 som er atskilt fra den fremre del ved hjelp av et muffeholdeorgan 34. I den viste utførelsesform omfatter dette muffeholdeorgan en utadragende ring som er utformet på det rørformete legeme 24. The tubular body 24 also comprises a main part 32 which is separated from the front part by means of a sleeve holding member 34. In the embodiment shown, this sleeve holding member comprises a projecting ring which is formed on the tubular body 24.

Det rørformete legemes 24 bakre ende 36 er koplet til et plastrør ved anvendelse av presspasning og med en løsningsmiddels-binding. To motstående flenser 38, 39 løper utad fra det rør-formete legeme 24 i nærheten av den bakre ende 36 med henblikk på å samvirke med spalter 40, som er utformet i muffen 20, noe som vil bli beskrevet nedenfor. The rear end 36 of the tubular body 24 is connected to a plastic pipe using a press fit and with a solvent bond. Two opposed flanges 38, 39 extend outwardly from the tubular body 24 near the rear end 36 for the purpose of cooperating with slots 40 formed in the sleeve 20, which will be described below.

Muffen 2 0 omfatter en fremre del 4 2 som er utformet med innvendige gjenger som er innrettet til å samvirke med flensen 18, samt en bakre del 44 som har mindre innerdiaroeter enn ringens 34 ytterdiameter. Ringen 34 tjener således til å hindre muffen 20 i å bevege seg fremad forbi den i fig. 2 viste stil-ling . The sleeve 20 comprises a front part 4 2 which is designed with internal threads which are arranged to cooperate with the flange 18, as well as a rear part 44 which has smaller inner diameters than the outer diameter of the ring 34. The ring 34 thus serves to prevent the sleeve 20 from moving forward past the one in fig. 2 showed style.

Den bakre del 44 har en bakre ende 4 6 med en innvendig flate 48 som danner en knasttetning mot hoveddelens 32 overflate. Hoveddelen 32 er konisk utad i retning fremover, slik at når muffen 20 beveger seg fremover vil det opptre en økende kompresjon mellom innersiden 48 og hoveddelens 32 overflate. Dette arrangement bevirker en særlig god fluidumtetning. The rear part 44 has a rear end 46 with an internal surface 48 which forms a cam seal against the surface of the main part 32. The main part 32 is conical outwards in the forward direction, so that when the sleeve 20 moves forward, an increasing compression will occur between the inner side 48 and the surface of the main part 32. This arrangement results in a particularly good fluid seal.

Som nevnt ovenfor danner muffens 20 bakre del 44 spalter 40, hvilke som det tydelig fremgår av fig. 1 og 3 har deres bredeste del ved den bakre ende 4 6 av den bakre del 4 4 og for øvrig er innsnevret i retning fremover. Disse stort sett V-for-mete spalter bidrar til å gi muffen 20 den riktige elastisitet for bevegelse langs hoveddelen 32. Når muffen 20 er skrudd fri As mentioned above, the rear part 44 of the sleeve 20 forms slits 40, which, as is clear from fig. 1 and 3 have their widest part at the rear end 4 6 of the rear part 4 4 and are otherwise narrowed in the forward direction. These generally V-shaped slots help to give the sleeve 20 the proper elasticity for movement along the main part 32. When the sleeve 20 is unscrewed

av flensen 18, vil flensene 38, 39 dessuten være fanget i spaltene 40, og innbyrdes dreining mellom muffen 2 0 og det rør-formete legeme 24 vil derved være hindret. Å hindre slik innbyrdes dreining er viktig, idet det ellers ville være meget vanskelig å frigjøre hankoplingsdelen 10 fra hunkoplingsdelen 12 etter at disse har vært sammenkoplet. of the flange 18, the flanges 38, 39 will also be trapped in the slots 40, and mutual rotation between the sleeve 20 and the tube-shaped body 24 will thereby be prevented. Preventing such mutual rotation is important, as it would otherwise be very difficult to release the male connection part 10 from the female connection part 12 after they have been connected.

Det er hensiktsmessig at rørkoplingen er fremstilt som en plastkonstruksjon. Muffen 2 0 kan være utformet med to vinger som kan gripes av operatøren med henblikk på en lettvint innsettelse og uttaking av hankoplingsdelen i hunkoplingsdelen 12. It is appropriate that the pipe connection is produced as a plastic construction. The sleeve 20 can be designed with two wings that can be grasped by the operator with a view to easy insertion and removal of the male connection part in the female connection part 12.

Som det vil fremgå danner innersiden 48 en knasttetning As will be seen, the inner side 48 forms a cam seal

eller en ringtetning, som komprimeres av den fremadrettede bevegelse av muffen 20 langs hoveddelen 32. Den av innersiden 48 dannete tetning er avpasset til muffen 20, slik at denne er sélvsentrerende. Ved anvendelse av dette arrangement er det frembrakt en særlig god fluidumtett tetning, og bøssingen 20 or an annular seal, which is compressed by the forward movement of the sleeve 20 along the main part 32. The seal formed by the inner side 48 is adapted to the sleeve 20, so that it is self-centering. By using this arrangement, a particularly good fluid-tight seal has been produced, and the bushing 20

samt det rørformete legeme 24 har organer som samvirker for å and the tubular body 24 has organs that work together to

hindre innbyrdes dreininger når det er ønskelig å åpne koplingen. prevent mutual rotations when it is desired to open the coupling.
