CLASS INTERNATIONAL SWEDISH A 61 m30 k: 1102 PATENT AND REGISTRATION AGENCY Arts. 9918/1955 of 3/11 195Hdrtill a drawing J A. S WISMAR, DANDERYD Device for introducing liquid, especially Mod, in a container with perforable stopper The present invention relates to such devices, so-called tapping needles, which are used for introducing liquid, separate blood, in connection with blood donation, a by means of a perforable rubber stopper or similar closed container while simultaneously expelling the air displaced by the introduced liquid from the container, which device comprises at least one needle pointed for perforating the container stopper, through which the liquid is inserted into the container, saint a number of channels for the outflow of air through the plug, which channels are preferably arranged in connection with said cannula, so that all the container plug only needs to be perforated in a single place.

Vid hittills kanda utforanden av sadana s. k. tappningskanyler fi3religger en icke obetydlig risk for, att den, som skall ombesorja anordningens anbringande vid behallaren och behallareproppens samtidiga perforering, kommer at antingen den fOr inforande i behallaren avsedda delen av kanylen eller sj.alva behallareproppens Oversida och darned aventyrar den onskvarda steriliteten hos dessa delar. Fareliggande uppfinning syftar till att undanroja derma risk och till att astadkonuna en forbattrad tappningskanyl, som i sitt i behallareproppen .fastsatta funktionslage Oven skyddar behallareproppens .Oversida mot luftburna fOroreningar. In the case of known designs of such so-called cannulas, there is a not insignificant risk that the person who is to arrange for the device to be attached to the container and the simultaneous perforation of the container stopper will either the part of the cannula intended for insertion into the container or endangers the undesirable sterility of these parts. The present invention aims to eliminate this risk and to provide an improved tapping cannula which, in its functional state fixed in the container stopper, also protects the upper surface of the container stopper from airborne contaminants.

Det for uppfinningsforemalet kannetecknande bestar i, att med kanylen Or forbunden en flansliknande skyddsplatta, som Or utf or-mad far att tficka den av kan.ylen genomborrade behallareproppen, och att luflutstr5mningskanalerna liverga i utatriktade kanaler i namnda skyddsplatta, som foretradesvis utmynna invid skyddsplattans ytterkant. The object of the invention may be that a flange-like protective plate connected to the cannula is formed, which is formed to have the container plug pierced by the cannula, and that the air outflow channels live in outwardly directed channels in said protective plate, which are preferably externally protected. .

Tappningskanylen 1 i 'fig. 1-3 Or utford ett styeke av plast ochlorsedd med en forhallandevis smal ovre ande 2, pa vilken normalt en icke visad -vatsketillforselslang Or patradd. Kanylens nedre andparti 3 Or 'Angst ned utformat med en spets 4 .och darovanfor med sidoriktade utloppsoppningar 5 fi5r den genom heIa kanylens langd sig strackande vatskepassagen 6. Pa sin utsida ,ar kanylens nedre andparti 3 fiirsett med langslopande spar eller rafflor 7, vilka vid kanylens inpressning genom en vid 8 i fig. 1 antydd perforerbar propp i en behallaremynning 9 forbliva Oppna ocb. armed Mika den av den tillforda vatskan undantrangda lulten i behallaren att fritt avg. Alt anvanda en separat luftningskanyl blir darigenom onodigt. The tapping cannula 1 in FIG. 1-3 Or challenge a styeke of plastic ochlorsedd with a relatively narrow upper spirit 2, on which normally a not shown -water supply hose Or patradd. The lower end portion 3 of the cannula is angularly formed with a tip 4 and above it with lateral outlet openings 5 for the water passage 6 extending through the entire length of the cannula. the pressure of the cannula through a perforable plug indicated at 8 in Fig. 1 in a container mouth 9 remains open. armed Mika the lute displaced by the supplied liquid in the container to freely avg. Anything using a separate aeration cannula thus becomes unnecessary.

Enligt foreliggande uppfinning Or kanylen 1 mellan slanganslutningsanden 2 och proppperforeringsdelen 3 forsedd med en. flansliknan.deskyddsplatta 10. Denna skyddsplatta 10 Or utformad med sá stor diameter, att den fullstandigt kommer att tacka behallareproppen 8, Oven om perforeringen av proppen skulle ske nagot excentriskt, vilket Or vanligt. For att den genom sparen 71 kanylens nedre andparti 3 ur behallareri utstrommande luften .skall fritt kunna avga, Oven oni skyddsplattan vid kanylens inpressning genom behallareproppen 8 skulle komma att ligga tatt an mot proppens oversida, Or skyddsplattan 10 pa sin undersida forsedd med radiella luftavledningsspar 11. According to the present invention, the cannula 1 between the hose connecting end 2 and the plug perforating part 3 is provided with a. flange-like.protection plate 10. This protection plate 10 Or designed with such a large diameter that it will completely thank the container plug 8, Although the perforation of the plug would be somewhat eccentric, which Or usually. In order that the air flowing through the lower end portion 3 of the cannula from the container into the container should be able to discharge freely. .

Out kanylen levereras frau tillverkaren i bruksfardigt, steriliserat skick, km den lampligen sasom antytts i fig. 3, vara forsedd med ett skyddsholje 12, som med en rorformad del 2-- — omsIuter kanylens nedre andparti 3 oak med en flansliknande del 12' tacker undersidan av skyddsplattan 10. The cannula is delivered from the manufacturer in a ready-to-use, sterilized condition, as appropriate, as indicated in Fig. 3, to be provided with a protective housing 12, which with a tubular part 2-- - encloses the lower end portion 3 of the cannula with a flange-like part 12 '. the underside of the protection plate 10.

Den i fig. 4 oar 5 visade kanylen 13 dr till skillnad frau den nyss beskrivna sarrunanfogad av tvá delar, vilket beror pa att utslappandet av luften ur behallaren liar ordnats pa ett annat satt men fortfarande sa, att sarskild luftningskanyl blir 6verfloclig och behfillareproppen salunda endast behover genomborras i en punkt. Vatskeinforingskanylens nedre andparti 14 är i fig. 4 oar 5 utvandigt slat, medan axiellt fOrlopande rannformiga spar 15 istallet aro upptagna pa insidan av en. underifran pa kanylen patradd hylsa 16, som upptill är forsedd med en ,flans 17 med stor diameter., Mot oversidan av denna hyls-flans 17är en motsvarande flans 18 pa sjalva kanylen 13 fastlimmad eller pa annat lampligt satt fixerad. Mellan flansarna ar anordnat -eft utlopp 19 for sparens 15 ovre- andar, vilket utlopp utmynnar i sidled invid flansarnas ytterkant. Utforandet enligt fig. 4 och 5 ãr naturligtvis sarskilt lampligt vid tappningskanyler, som skola anvandas yid behallareproppar air mycket mjukt .elastiskt material, vilket skulle kunna fylla ut luftningssparen 7 I kanylen enligt fig. 1-3 oak darmed aventyra den fria luftavgangen fran behallaren. The cannula 13 shown in Fig. 4 differs from the one just described by two parts, which is due to the fact that the release of the air from the container is arranged in a different way but still so that the special aeration cannula becomes superfluous and the container plug only needs to be pierced at one point. The lower end portion 14 of the water insertion cannula is shown in Fig. 4 on the outside, while axially extending annular grooves 15 are instead received on the inside of one. from below the sleeve 16, which is patterned, is provided at the top with a flange 17 of large diameter. Arranged between the flanges - after outlet 19 for the upper spirits of the spar 15, which outlet opens laterally next to the outer edge of the flanges. The design according to Figs. 4 and 5 is of course particularly suitable for tapping needles, which should be used with container plugs in very soft, elastic material, which could fill the aeration savings 7 in the cannula according to Figs. 1-3 and thus vent the free air outlet from the container.

Vid bada kanylutforandena fir det tyclligt att den m.ycket vida, flansliknande skyddsPlattan 10 resp. 17, 18 effektivt forhindrar, att man. vid hanteringen ay kanylen oak framforallt vid genombormingen av behallarepropPen med handen glider fram ,Over del sterila kanylandpartiet 3 resp. 14, 16. Samtidigt skyddas givetvis amen behallareproppen mot beroring oak nedsmutsning under sjalva vatskeinforandet. lianylen blir darmed icke bIott sakrare 'titan kraver samtidigt mindre forsiktighet och vanaf vid hanteringen. In both case of the needle designs, it is apparent that the very wide, flange-like protective plate 10 resp. 17, 18 effectively prevents, that one. when handling the cannula oak, especially when piercing the container plug with the hand sliding forward, Over part sterile cannula land portion 3 resp. 14, 16. At the same time, of course, the amen container stopper is protected against touch or contamination during the actual water introduction. lianylene thus does not become much safer 'titanium requires at the same time less care and caution when handling.
