Description
Sterilkoker. Sterile cooker.
Foreliggende oppfinnelse angår en sterilkoker, omfattende en beholder med anordninger for frembringelse eller tilførsel av damp og med et lokk som lukker beholderen. Slike sterilkokere anvendes ofte i operasjonsrom for øyeblikkelig steriliser-ingsbehov, og det er derfor ønskelig å hin-dre at dampen ved kokingen sprer seg i rommet, særlig da kokingen må være in-tens for at instrumentene og forbindings-sakene skal bli absolutt sterile. Oppfinnelsen har til hensikt å skaffe en enkel og pålitelig anordning for dette formål, som dessuten er billig i drift og arbeider stille uten å frembringe forstyrrende lyd. Dette oppnås ifølge oppfinnelsens vesentlig ved at det på utsiden av beholderen og ved dennes øvre kant er anordnet en rundt om forløpende kjølekanal og at lokket er forsynt med minst en rundt 'om gående flens, som når lokket er lukket befinner seg umiddelbart ved en av kjølekanalens veg-ger, slik at damp, som kommer inn mellom flensen og kjølekanalen, kondenseres og herved forhindres fra å strømme ut av kokeren. The present invention relates to a sterile cooker, comprising a container with devices for generating or supplying steam and with a lid that closes the container. Such sterile cookers are often used in operating rooms for immediate sterilization needs, and it is therefore desirable to prevent the steam during boiling from spreading in the room, especially as the boiling must be intense for the instruments and dressings to become absolutely sterile. The invention aims to provide a simple and reliable device for this purpose, which is also cheap to operate and works quietly without producing disturbing noise. According to the invention, this is essentially achieved by the fact that on the outside of the container and at its upper edge there is arranged a cooling channel that runs all the way around and that the lid is provided with at least one surrounding flange, which when the lid is closed is located immediately at one of the cooling channel's walls, so that steam, which enters between the flange and the cooling channel, is condensed and thereby prevented from flowing out of the boiler.
Oppfinnelsen skal forklares i det føl-gende under henvisning til tegningen, som viser en utførelsesform av oppfinnelsen. The invention will be explained in the following with reference to the drawing, which shows an embodiment of the invention.
Fig. 1 er et perspektivriss av en sterilkoker med avtatt lokk og Fig. 1 is a perspective view of a sterile cooker with the lid removed and
fig. 2 er et snitt etter linjen II-II i fig. 1. fig. 2 is a section along the line II-II in fig. 1.
Beholderen 1 er anordnet ovenpå en dampfrembringer 2, som kan være utført på vilkårlig måte, f. eks. med dampslanger i vann eller som en elektrodedampfrem-bringer. Beholderens vegg 3 er ved den øvre kant tilsluttet en utstående, horison-tal kantring 4 med nedover bøyet kant 5. I vinkelen mellom beholderveggen 3 og kantringen 4 er det anordnet en rundt om beholderen gående kjølekanal 6, som er dannet ved at en i tverrsnitt vinkelformet metallring 7 er fastsveiset ved kantringen 4 og beholderveggen 3. Den som en hul bjelke utført kjølekanal tjener samtidig til avstivning av beholderveggens øvre del og kantringen 4. Ved 8 er kjølekanalen lukket ved en mellomvegg, og i kort av-stand på begge sider av denne er kjøle-kanalen forsynt med to rørtilslutninger 9 for inngående og 10 for utgående kjøle-vann. Beholderen kan lukkes ved hjelp av et oppslagbart eller avtagbart lokk 11. Dette lokk er forsynt med for det ene en utstående flens 12, som ligger an med sin underkant langs kantringen 4, og for det annet med en ned i beholderen ragende flens 13 som ligger tett inntil den øvre del av den kjølte beholdervegg. The container 1 is arranged on top of a steam generator 2, which can be designed in any way, e.g. with steam hoses in water or as an electrode steam generator. The container's wall 3 is connected at the upper edge to a protruding, horizontal edge ring 4 with a downwardly bent edge 5. In the angle between the container wall 3 and the edge ring 4, a cooling channel 6 running around the container is arranged, which is formed by a cross-section angular metal ring 7 is welded to the edge ring 4 and the container wall 3. The cooling channel, designed as a hollow beam, simultaneously serves to stiffen the upper part of the container wall and the edge ring 4. At 8, the cooling channel is closed by an intermediate wall, and at a short distance on both sides of this cooling channel is provided with two pipe connections 9 for incoming and 10 for outgoing cooling water. The container can be closed using a hinged or removable lid 11. This lid is provided with, on the one hand, a protruding flange 12, which abuts with its lower edge along the edge ring 4, and, on the other hand, with a flange 13 projecting down into the container, which is close to the upper part of the cooled container wall.
Når ved steriliseringen den frembrakte damp søker å passere mellom kjølekanalen og flensene 13 og 12, avkjøles den først under flensen 13 og kondenseres delvis på den del av den kjølte beholdervegg som befinner seg under flensen 13. Ved at flensen 12 likeledes kjøles ved anlegg mot kjølekanalens øvre vegg, avledes varme fra flensen 13 til flensen 12, idet flensen 13 også kjøles direkte fra kjølekanalens inner-vegg. Når derfor damp trenger inn i det smale mellomrom mellom flensen 13 og beholderveggen, vil den effektivt nedkjøles og kondenseres, hvoretter kondensatet renner tilbake i beholderen. Noen nevne-verdig kondensasjon under flensen 12 be-høver derfor normalt ikke å forekomme. When, during sterilization, the produced steam tries to pass between the cooling channel and the flanges 13 and 12, it first cools below the flange 13 and partially condenses on the part of the cooled container wall that is located below the flange 13. By the fact that the flange 12 is also cooled by contact with the cooling channel upper wall, heat is diverted from the flange 13 to the flange 12, as the flange 13 is also cooled directly from the inner wall of the cooling channel. When therefore steam penetrates into the narrow space between the flange 13 and the container wall, it will effectively cool down and condense, after which the condensate flows back into the container. Any significant condensation under the flange 12 therefore normally does not need to occur.
Rørtilslutningene 9 og 10 kan forbin-des med en vanntilførsel resp. et avløp, og avstengningskran er bare nødvendig i den inngående kjølevannsledning. Kantringen 4 kan i sin helhet eller under flensen 12 gjøres noe hellende innover, slik at vann på kantringen renner til beholderen, og den utstikkende flens 12 bør da tilpasses etter kantringens helning. Den i kjøle-kanalen inngående metallremse 7 er på tegningen vist bøyet i rett vinkel men kan også gis en annen form og f. eks. bestå av en plan skråttstilt metallremse. Beholderen 1 kan være varmeisolert utvendig, og også andre modifikasjoner av den viste utfør-else kan foretas, uten at oppfinnelsens prinsipp avvikes. The pipe connections 9 and 10 can be connected with a water supply or a drain, and shut-off valve is only required in the incoming cooling water line. The tilt ring 4 as a whole or under the flange 12 can be made slightly inward, so that water on the tilt ring flows to the container, and the protruding flange 12 should then be adapted to the inclination of the tilt ring. The metal strip 7 included in the cooling channel is shown in the drawing bent at a right angle, but can also be given a different shape and e.g. consist of a flat inclined metal strip. The container 1 can be thermally insulated on the outside, and other modifications of the shown embodiment can also be made, without deviating from the principle of the invention.
