Description
Den foreliggende oppfinnelse vedrører en anordnincr ved sylindrisk prøvetagningsbeholder hvorved dennes årme ende kan lukkes av en sylindrisk propp av elastomert materiale. The present invention relates to a device for a cylindrical sampling container whereby its lower end can be closed by a cylindrical plug of elastomeric material.
For medisinsk, biologisk eller laboratorie-bruk har forskjellige slags propper vært anvendt for tetting av beholdere, slik som blodproveror eller lignende. Slike propper må være slik at de hindres fra utilsiktet å losne fra beholderen på grunn av virkningen av det trykk som frembringes når proppen innfores For medical, biological or laboratory use, various types of stoppers have been used to seal containers, such as blood samples or the like. Such stoppers must be such that they are prevented from being inadvertently detached from the container due to the action of the pressure produced when the stopper is inserted
i proverorets munning, eller på grunn av okende indre trykk på grunn av stigende temperatur. Proppen skal samtidig være slik anordnet at den gir en tett lukking av beholderen. For dette formål "har slike propper hittil vært foreslått i en rekke forskjellige utfdreiser. in the mouth of the prover, or due to increasing internal pressure due to rising temperature. The stopper must also be arranged in such a way that it closes the container tightly. To this end, "such plugs have so far been proposed in a number of different ways.
I US patent nr. 3,057,502 vises en propp med en rekke ringformete ribber i den ytre omkrets av det hule sylindriske legeme som utgjor proppen, hvilken er fremstilt av elastisk .plastmateriale. Den ytre omkrets av disse ringformete. ribber utgjor'kontaktflater mot innsiden av glassroret. Nevnte patent beskriver videre ribbeflater som er ru for å oke frik-sjonen mellom innsiden av glasset og proppen. US Patent No. 3,057,502 shows a stopper having a series of annular ribs on the outer circumference of the hollow cylindrical body which constitutes the stopper, which is made of elastic plastic material. The outer circumference of these ring-shaped. ribs form contact surfaces against the inside of the glass tube. Said patent further describes ribbed surfaces which are rough to increase the friction between the inside of the glass and the stopper.
US patent nr. 3,136,440 vedrorer en propp av elastomert materiale som er selvforseglende for anvendelse for en beholder. Denne.propp består av et sylindrisk legeme med et storre flens-lignende hode utformet i ett med den ovre ende av legemet. I nevnte propp og hode er henholdsvis utformet uttagninger, og disse to uttagninger er adskilt fra hverandre ved et diafragma med konkavt tverrsnitt ved den ovre del og et konvekst tverrsnitt på undersiden. Den ytre diameter for proppen er litt storre enn beholderens indre diameter, hvorved fås godt tettende anlegg. Rundt proppen umiddelbart inne ved hodet er der videre anordnet et rundtgående spor som tjener til å redusere til et minimum eller avlaste spenninger nær dette parti av proppen resulterende fra motstanden for hodet mot sammenpressing av proppen når denne innfores i beholderens åpning. US Patent No. 3,136,440 relates to a plug of elastomeric material which is self-sealing for use in a container. This plug consists of a cylindrical body with a larger flange-like head formed integrally with the upper end of the body. In the said plug and head, recesses are respectively designed, and these two recesses are separated from each other by a diaphragm with a concave cross-section at the upper part and a convex cross-section on the underside. The outer diameter of the stopper is slightly larger than the inner diameter of the container, which results in a tight fitting. Around the stopper immediately inside the head, there is further arranged a circumferential groove which serves to reduce to a minimum or relieve stresses near this part of the stopper resulting from the resistance of the head against compression of the stopper when it is inserted into the opening of the container.
De tidligere propper, heri inkludert de to som ovenfor er nevnt i forbindelse med de amerikanske patenter, er anordnet således at de ligger i tett anlegg mot beholderen i en stilling i hvilken proppen er innpresset i beholderen. The previous plugs, herein including the two mentioned above in connection with the American patents, are arranged so that they lie in tight contact with the container in a position in which the plug is pressed into the container.
De kjente propper svarer ikke helt til sin hensikt når de The known stoppers do not quite answer their purpose when they
skal presses inn i beholderen . Slike propper blir gjen-tagende ganger tatt ut av beholderen for å ta nye prover. Under de forhold hvor proppen holdes innpresset i beholderen, vil luften i beholderen holdes innpresset. Når derfor proppen trekkes av beholderen, vil den sprette ut av denne med en viss kraft, og hvis innholdet er væske, er denne tilboyelig til samtidig å sprute ut, idet proppen losner fra beholderen. Efter at proppen er fjernet vil det flytende innhold ofte vedhefte beholderens innside ved munningen, hvorved friksjonskraften mellom proppen og beholderveggen reduseres, hvilket bringer proppen til gradvis å sige ut, slik at den lett losner ved hjelp av trykket i den sammenpressede luft. Som et resultat av dette vil et proveror for blodprover eller lignende ha den ulempe at blod spilles eller sproytes ut over operatoren. must be pressed into the container. Such plugs are repeatedly taken out of the container to take new samples. Under the conditions where the stopper is kept pressed into the container, the air in the container will be kept pressed. Therefore, when the stopper is pulled from the container, it will bounce out of it with a certain force, and if the contents are liquid, this is liable to spurt out at the same time, as the stopper loosens from the container. After the stopper is removed, the liquid contents will often adhere to the inside of the container at the mouth, whereby the frictional force between the stopper and the container wall is reduced, causing the stopper to gradually leak out, so that it is easily loosened by the pressure of the compressed air. As a result of this, a proveror for blood samples or the like will have the disadvantage that blood is spilled or sprayed over the operator.
En vanlig gummipropp for anvendelse i forbindelse med blodproveror er formet slik at kontaktflaten mellom proppen og beholderen blir så stor som mulig. I slike gummipropper er propplegemet, bortsett fra dettes ovre endeparti, utformet slik at de har en storre ytre diameter enn den indre diameter av beholderen, og for at blodprovenålen lett skal kunne trenge igjennom proppen, er denne utformet med fordypede partier. Hvor proppen skal gjeninnsettes i beholderen efter forst å være tatt ut,er den redusert i styrke og mere tilboyelig til å bevirke av de ovennevnte problemer gjor seg gjeldende, sammenlignet med en propp for anvendelse i forbindelse med et vanlig konisk proveror. A normal rubber stopper for use in connection with blood samplers is shaped so that the contact surface between the stopper and the container is as large as possible. In such rubber stoppers, the stopper body, apart from its upper end part, is designed so that they have a larger outer diameter than the inner diameter of the container, and so that the blood sample needle can easily penetrate the stopper, this is designed with recessed parts. Where the plug is to be reinserted into the container after first being removed, it is reduced in strength and more likely to cause the above-mentioned problems to occur, compared to a plug for use in connection with an ordinary conical prover.
Det er en hensikt med oppfinnelsen å tilveiebringe en propp It is an object of the invention to provide a plug

En annen hensikt med oppfinnelsen er å tilveiebringe en.propp som Another purpose of the invention is to provide a stopper which

Anordningen ifølge oppfinnelsen kjennetegnes, av de i og for seg kjente trekk at beholderens sylindriske munnina har en. rundtgående innadrettet vulst og at et ringformet spor er utformet i . proppen, The device according to the invention is characterized, by the per se known features, that the cylindrical mouth of the container has a. circumferential inwardly directed bead and that an annular groove is formed in . the plug,
på en viss avstand fra dens øvre ende, idet proppen er således anordnet at den når den raaer inn i beholderens åpne ende tetter denne ved anlegg av vulsten, mot det parti av proppen som ligaer mellom nevnte spor og dens øvre ende, samt blir fastholdt i tettende stilling når den av beholderens indre trykk skyves ut.til inngrep med vulsten i sporet. Ifølge et ytterligere trekk ved oppfinnelsen er proppen konisk ved det nedre endeparti oa det ringformede spor begrenses av et ringformet fremspring på det mellomliagende parti av den koniske del, idet det ringformede fremsprings ytre omkretsflate stort sett ligger i plan med proppens sylindriske yttérflate. at a certain distance from its upper end, the stopper being arranged in such a way that when it enters the open end of the container, it seals the latter by contact with the bead, against the part of the stopper that connects between the aforementioned groove and its upper end, and is retained in sealing position when it is pushed out by the container's internal pressure to engage with the bead in the groove. According to a further feature of the invention, the plug is conical at the lower end part and the annular groove is limited by an annular projection on the intermediate part of the conical part, the outer circumferential surface of the annular projection being largely flush with the cylindrical outer surface of the plug.
For at oppfinnelsen skal forstås bedre, skal den beskrives nærmere under henvisning til. den; vedlagte tegning, hvor: Fig. 1 viser en propp ifolge oppfinnelsen sett fra siden og delvis i,snitt. In order for the invention to be better understood, it shall be described in more detail with reference to it; attached drawing, where: Fig. 1 shows a plug according to the invention seen from the side and partly in section.

Den i fig. 1 viste propp er betegnet med 1 og er laget .av The one in fig. 1 stopper shown is denoted by 1 and is made .of
elastisk materiale, som f.eks. vulkanisert gummi, hovedsakelig bestående av butylgummi, og fremviser en hardhet på ca. 50° elastic material, such as vulcanized rubber, mainly consisting of butyl rubber, and exhibits a hardness of approx. 50°
når dens hodedel er presset fra siden ved enhard- when its head part is pressed from the side by a hard-
hetsprover ifolge Japanese Industrial Standard. Proppen 1 heat tests according to the Japanese Industrial Standard. Plug 1
er innpasset eller innsatt i munningen på beholderen, f.eks. et tomt blodprbverdr 2 som har en ringformet, innadragende vulst på kanten av beholdermunningen for å tette nevnte ror 2. I de tilfeller hvor roret er laget av glass, kan nevnte vulst være den som nodvendigvis dannes ved oppvarming av beholdermunningen. Dersom roret har en kapasitet på 7 ml, har beholderen en indre diameter på ca. 10,50 mm. Proppen 1 består av et sylindrisk propplegeme 3 avsmalnende fra dens nedre parti 10 til dens nederste parti og har en maksimal diameter på ca. 11,8 mm, og av et storre hode 4 utformet i ett med det ovre parti av legemet. I den nedre endeflate av propplegemet 3 og i den ovre endeflate av propphodet 4 er der utformet uttagninger 5 og 6 for at blodprovenålen lett skal kunne trenge gjennom midtpartiet av proppen 1. Når, i dette tilfelle, en blodprovenål, som har en diameter på 0,80 mm, trenger igjennom med en.hastighet på 20 mm/min., regnes gjennomtrengningsmot-standen for ca. 1.3608 kg., målt ifolge Chatillons lære. Som ovenfor nevnt er propplegemet utfort som en relativt elastisk konstruksjon. Propplegemet 3 er forsynt med et ringformet spor 9, anordnet i avstand fra den nedre ende av propphodet 4 og ved den del av den ytre omkrets 7 av legemet som er i umiddelbar nærhet av det nedre ende parti 10 av propplegemet 3. Det ringformete spor 9 har et lengdesnitt hvor en linje som for-binder sporets ovre kant El på siden av hodet 4 og sporets bunn II skrånder innover mot nevnte bunn 11, og en linje som for-binder sporets andre kant E2 og sporets bunn 11 er perpendi-kulær på midtaksen av propplegemet. Sporets profil kan imidlertid være utformet på hvilken som helst måte forutsatt at den passer sammen med beholdervulsten. is fitted or inserted into the mouth of the container, e.g. an empty blood sample tube 2 which has an annular, indenting bead on the edge of the container mouth to seal said tube 2. In cases where the tube is made of glass, said bead may be the one that is necessarily formed by heating the container mouth. If the rudder has a capacity of 7 ml, the container has an internal diameter of approx. 10.50 mm. The plug 1 consists of a cylindrical plug body 3 tapering from its lower part 10 to its bottom part and has a maximum diameter of approx. 11.8 mm, and of a larger head 4 formed in one with the upper part of the body. In the lower end surface of the stopper body 3 and in the upper end surface of the stopper head 4, recesses 5 and 6 are designed so that the blood sample needle can easily penetrate through the middle part of the stopper 1. When, in this case, a blood sample needle, which has a diameter of 0 ,80 mm, penetrates at a speed of 20 mm/min., the penetration resistance is calculated to be approx. 1.3608 kg., measured according to Chatillon's teaching. As mentioned above, the plug body is designed as a relatively elastic construction. The plug body 3 is provided with an annular groove 9, arranged at a distance from the lower end of the plug head 4 and at the part of the outer circumference 7 of the body which is in the immediate vicinity of the lower end part 10 of the plug body 3. The annular groove 9 has a longitudinal section where a line connecting the track's upper edge El on the side of the head 4 and the track's bottom II slopes inwards towards said bottom 11, and a line connecting the track's other edge E2 and the track's bottom 11 is perpendicular to central axis of the plug body. However, the profile of the groove can be designed in any way provided it is compatible with the container bead.
Når propplegemet 3 gradvis loftes fra helt innpresset stilling i blodproveroret 2 opp mot den ovre ende på grunn av f.eks. det indre trykk i blodproveroret, vil det ringformete spor 9 falle-sammen med rorvulsten 2 og hindrer videre utglidning av propplegemet. Sporet er utformet i propplegemet i avstand fra den ovre ende av dette, fortrinnsvis i nærheten av den nedre ende. Sporets beliggenhet bestemmes av proppens hardhet. beholdervulstens.hoyde, eller spordybden. Beholdervulstens hoyde må imidlertid være begrenset til det området i hvilket proppen er innsettbar i beholderen. When the plug body 3 is gradually raised from a fully pressed position in the blood sampler 2 up towards the upper end due to e.g. the internal pressure in the blood sampler, the annular groove 9 will coincide with the tube bead 2 and prevents further slipping of the plug body. The groove is formed in the plug body at a distance from the upper end thereof, preferably near the lower end. The location of the groove is determined by the hardness of the plug. container bead.height, or groove depth. However, the height of the container bead must be limited to the area in which the plug can be inserted into the container.
Under henvisning til figurene 2 til 4 vil proppens virkemåte ifolge oppfinnelsen nå bli beskrevet. Det tomme blodproveror 2 forut for blodproving er hermetisk tettet av proppen 1, og roret er i en tom tilstand. Propplegemet 3 er fort inn i blod-proverorets 2 munning helt til underkanten av hodet 4. Når nålen for et blodproveinstrument derpå trenger gjennom"proppen 1 for å utfore en blodprove, minskes trykket inne i roret, With reference to Figures 2 to 4, the operation of the plug according to the invention will now be described. The empty blood sample tube 2 prior to blood sampling is hermetically sealed by the plug 1, and the tube is in an empty state. The stopper body 3 is quickly inserted into the mouth of the blood sampler 2 all the way to the lower edge of the head 4. When the needle of a blood sampling instrument then penetrates the stopper 1 to perform a blood sample, the pressure inside the tube is reduced,
og proppen blir manuelt demonterbar. and the plug becomes manually removable.
Hvor den vanligé blodprove (erythcrocyte-nummer, leukocyte-nummer eller hematocrit verdi) blir utfort, blirVen betydelig blodmengde provet i det evakuerte blodproveror 2 som på for-hånd er fyllt med blod-antikoaguleringsmiddel. Proppen 1 Where the usual blood sample (erythrocyte number, leukocyte number or hematocrit value) is carried out, a considerable amount of blood is usually sampled in the evacuated blood sampler 2 which is filled in advance with blood anticoagulant. Plug 1
blir derefter demontert (se fig. 2) fra roret og blodet blir uttatt derfra noyaktig i den utstrekning som er nodvendig for proven på et objekt. Proppen 1 blir så igjen innfort (se fig. is then dismantled (see fig. 2) from the rudder and the blood is taken from there precisely to the extent necessary for the test on an object. Plug 1 is then inserted again (see fig.
3). Det med proppen igjentettede ror blir plassert på et blodblandeinstrument til neste prove blir utfort, eller blir manuelt ristet ved utfdreisen av neste prove og på den måten blande blodet med antikoaguleringsmiddelet. De foregående prosesser blir gjentatte ganger utfort til provene er fullfort. Ved nevnte prosesser kleber ofte proveblodet til proppen 1 3). The tube sealed with the stopper is placed on a blood mixing instrument until the next sample is withdrawn, or is manually shaken when the next sample is withdrawn and thus mixes the blood with the anticoagulant. The preceding processes are repeated until the sample is complete. In the aforementioned processes, the sample blood often sticks to the plug 1
og minsker friksjbnskoeffisienten mellom denne og innsiden av blodproveroret 2, slik at proppen blir tilboyelig til å gli ut. Av denne grunn vil, selv når proppen 1 igjen blir presset helt inn i roret 2 til underkanten av propphodet 4, innforingen bevirke okt trykk i det indre hulrom 8 i roret, og dette okede trykk bevirker en viss hevning av proppen. Som vist i fig. 4, vil da det ringformete spor 9 i propplegemet 3 komme til inngrep med den ringformete vulst P på blodproveroret 2 tilstrekkelig til å stoppe utadbevegelsen av proppen 1. Derved hindres at proppen kan falle ut av roret. Også når blodproveroret legges eller snus opp-ned for å blande innholdet, vil det være sikret tett lukking. Det indre trykk i roret, som var oket ved proppens innpressing i roret, vil and reduces the coefficient of friction between this and the inside of the blood sampler 2, so that the plug becomes prone to slide out. For this reason, even when the plug 1 is again pressed completely into the rudder 2 to the lower edge of the plug head 4, the insertion causes increased pressure in the inner cavity 8 in the rudder, and this increased pressure causes a certain lifting of the plug. As shown in fig. 4, the annular groove 9 in the stopper body 3 will then come into engagement with the annular bead P on the blood sampler 2 sufficiently to stop the outward movement of the stopper 1. This prevents the stopper from falling out of the tube. Even when the blood sampler is placed or turned upside down to mix the contents, a tight seal will be ensured. The internal pressure in the rudder, which was increased when the plug was pressed into the rudder, will
reduseres når proppen beveger seg ut til inngrep mellom sporet ' og vulsten . Ved derpå folgende uttagning av proppen vil .derfor innholdet hindres fra kraftig utspruting av roret. is reduced when the plug moves out to engage between the groove and the bead. When the plug is subsequently removed, the contents will therefore be prevented from being forcefully ejected from the rudder.
Anordningen av det ringformete spor i umiddelbar nærhet til det nedre endeparti 10 av propplegemet 3, vil når proppen 1 innfores, forårsake at det ringformete nedre endeparti 10 lett kan boyes innover og vil således lette innforingen av proppen. The arrangement of the annular groove in the immediate vicinity of the lower end portion 10 of the stopper body 3, when the stopper 1 is inserted, will cause the annular lower end portion 10 to be easily bent inward and will thus facilitate the insertion of the stopper.
Fig. 5-7 illustrerer andre utfbrelsesformer av proppen ifolge oppfinnelsen. Fig. 5 viser en propp hvor det nedre endeparti 12 av propplegemet 3 er avsmalnende og har et ringformet fremspring 13 hvis ytre omkrets hovedsakelig er i plan med den ytre omkrets av propplegemet 3. Fig. 6 viser en annen propp som har en lignende konstruksjon til den i.fig. 1 viste, hvor det nedre endeparti 15 av propplegemet 3 viser en konisk avrundet flate. Fig. 7 viser en propp som har et ringformet spor 16 dannet i midtpartiet av den ytre omkrets på propplegemet. Fig. 5-7 illustrate other embodiments of the plug according to the invention. Fig. 5 shows a stopper where the lower end part 12 of the stopper body 3 is tapered and has an annular projection 13 whose outer circumference is mainly in plane with the outer circumference of the stopper body 3. Fig. 6 shows another stopper which has a similar construction to the one in fig. 1 showed, where the lower end part 15 of the plug body 3 shows a conical rounded surface. Fig. 7 shows a stopper which has an annular groove 16 formed in the middle part of the outer circumference of the stopper body.
Proppen ifolge oppfinnelsen er ovenfor beskrevet i forbindelse med blodproveror, men kan også brukes ved andre proveror forsynt med kantvulst i munningen. The stopper according to the invention is described above in connection with blood provers, but can also be used with other provers provided with an edge bead in the mouth.
Proppen ifolge oppfinnelsen muliggjor pålitelig hindring av infeksjon på grunn av at proppen spretter ut eller på grunn The plug according to the invention makes it possible to reliably prevent infection due to the plug popping out or due to grounding
av at innholdet blir spredt ved frigjoring av proppen. Intrahospital infeksjon, slik som infeksjon av serum cholangeitis eller syphilis med en blodprover via en pasients blod, som f.eks. i et eksamineringsrom eller laboratorierom blir spredt, er nylig blitt et alvorlig problem. Bruken av propper ifolge oppfinnelsen gjor det mulig fullstendig å hindre slik intrahospital infeksjon. Folgelig avhjelper proppen ifolge oppfinnelsen et forekommende uheldig forhold. of the contents being dispersed when the stopper is released. Intrahospital infection, such as infection of serum cholangitis or syphilis with a blood sample via a patient's blood, such as in an examination room or laboratory is spread, has recently become a serious problem. The use of plugs according to the invention makes it possible to completely prevent such intrahospital infection. Consequently, the plug according to the invention remedies an unfortunate situation that occurs.
