INDRETNING TIL STERILISATION ELLER FORBRÆNDING AF KIRURGISKE INSTRUMENTERDEVICE FOR STERILIZATION OR COMBUSTION OF SURGICAL INSTRUMENTS
Denne opfindelse vedrører en indretning til sterilisation 5 eller forbrænding af kirurgiske instrumenter, især af så danne instrumenter, hvor der er smittefare, hvilken indretning har en mikrobølgegenerator og en beholder med et ikke hermetisk aflukbart låg, og hvor de til sterilisering beregnede instrumenter kan indlægges i og opbevares inden i 10 beholderen.This invention relates to a device for sterilization or combustion of surgical instruments, especially of such instruments where there is a risk of infection, which device has a microwave generator and a container with a non-hermetically sealed lid, and where the instruments intended for sterilization can be inserted. and stored within the 10 container.
Det er kendt, at frembringelse af meget højfrekvente mikrobølger med en magnetron giver en temperaturforøgelse. Meget højfrekvente elektromagnetiske bølger, der virker på mate-15 rialer bestående af stoffer, som har en egnet kemisk struktur, forårsager molekylsvingninger, der frembringer stærk, hurtig opvarmning.It is known that producing very high frequency microwaves with a magnetron increases the temperature. Very high frequency electromagnetic waves acting on materials consisting of substances having a suitable chemical structure cause molecular oscillations which produce strong, rapid heating.
Brugen af apparater med mikrobølger har hidtil været be-20 grænset til industriel- eller hjemmeanvendelse, dog med begrænsninger hidrørende fra det respektive materiales struktur.The use of microwave appliances has heretofore been limited to industrial or home use, however, with limitations arising from the structure of the respective materials.
Det er også kendt, at sporedannende bakterier ødelægges af 25 den kombinerede mekaniske og termiske effekt, der forårsages af de meget høje frekvenser.It is also known that spore-forming bacteria are destroyed by the combined mechanical and thermal effect caused by the very high frequencies.
Således er det kendt fra SE fremlæggelsesskrift nr. 375 449 at sterilisere instrumenter ved hjælp af mikrobølger og 30 fugtighed i en beholder, idet vanddampen afgives fra en kilde herfor. Ved den kendte teknik er det dog ikke muligt at ødelægge instrumenter ved forbrænding, da temperaturen ikke kan stige tilstrækkeligt dertil, og steriliseringen er kun en overfladebehandling, ikke en gennemgribende eller 35 fuldstændig sterilisering. Endvidere anvendes en hermetisk lukket gastæt beholder, en art autoclave, der kan arbejde under forskelligt tryk og hvori der kan skabes vakuum. Der DK 170659 B1 2 anvendes til steriliseringen kemiske stoffer i gas- eller dampform, eller aerosoler, som er yderst giftige, med fare for brand og eksplosion under mikrobølgebestrålingen og med fare for forurening af selve instrumenterne, som ikke er 5 anvendelige som de er, og i steriliseringsindretningen skal ' vandet skilles fra materialet, der skal steriliseres. Der anvendes et sæt på tre stablede plader til at indeholde ma- * terialet, der skal steriliseres, hvilket betyder, at steriliseringen af metalgenstande ikke kan være homogen, idet 10 mikrobølgerne bevæger sig i en ret linie og derfor kun kan ramme de nederste genstande med mindre energi. Endelig er den nødvendige tid til sterilisering ca. 10 minutter for 100.000 sporer Bacillus Subtilis, og steriliseringstest udføres ikke direkte på materialet, men på sporestrimler.Thus, from SE Patent Specification No. 375,449, it is known to sterilize instruments by means of microwaves and humidity in a container, the water vapor being emitted from a source thereof. In the prior art, however, it is not possible to destroy instruments by combustion, as the temperature cannot rise sufficiently thereto and the sterilization is only a surface treatment, not a pervasive or complete sterilization. Furthermore, a hermetically sealed gas-tight container is used, a type of autoclave that can operate under different pressures and in which vacuum can be created. DK 170659 B1 2 is used for sterilizing chemical substances in gaseous or vapor form, or highly toxic aerosols, with the risk of fire and explosion during microwave radiation and with the danger of contamination of the instruments themselves, which are not usable as they are, and in the sterilizer, the water must be separated from the material to be sterilized. A set of three stacked plates is used to contain the material to be sterilized, which means that the sterilization of metal objects cannot be homogeneous, since the 10 microwaves move in a straight line and therefore can only hit the lower objects with less energy. Finally, the time needed for sterilization is approx. 10 minutes for 100,000 traces Bacillus Subtilis, and sterilization tests are not performed directly on the material but on trace strips.

Fra EP patentskrift nr. 0 185 931 kendes endvidere et industrielt anlæg, hvori en beholder forsynes med lag, som opvarmes under indvirkning af mikrobølger. Laget er et leje af granulerede stoffer, der er i stand til absorbere mikro-20 bølger og holdes i bevægelse (fluid bed) samt udsættes for mikrobølgers virkning, hvorved de opvarmes til høje temperaturer. Udløbsmaterialerne bliver til aske og/eller brænder ud, når de kommer i kontakt med dette materiale.Furthermore, EP patent specification 0 185 931 discloses an industrial plant in which a container is provided with layers which are heated under the influence of microwaves. The layer is a bed of granulated fabrics capable of absorbing microwaves and kept in motion (fluid bed) and exposed to the effect of microwaves, thereby heating them to high temperatures. The outlet materials turn into ash and / or burn out when they come into contact with this material.
25 De granulerede stoffer, som ikke brænder, har den funktion, at de overfører varme til affaldsmaterialerne, der skal ødelægges (hvilket kan ske i et uafbrudt forløb), og at behandle affald af fluid bed typen, hvorved fluid bed bringes på en høj temperatur af mikrobølgerne i stedet for op-30 varmning med forbrændingsolie eller gasvarmere. Mikrobølgerne er således opvarmningsmidlet.25 The granulated non-burning substances have the function of transferring heat to the waste materials to be destroyed (which can occur in an uninterrupted process) and to treat fluid bed type waste, thereby bringing fluid bed to a high temperature of the microwaves instead of heating with combustion oil or gas heaters. Thus, the microwaves are the heating agent.
Er der tale om ikke-metalliske instrumenter, brænder disse sammen med materialet, der skal ødelægges, når instrumen-35 terne kommer i kontakt med fint formalede materialer, som -¾ absorberer mikrobølgerne.In the case of non-metallic instruments, they burn together with the material to be destroyed when the instruments come into contact with finely ground materials which absorb the microwaves.
Begrænsninger ved brug af de kendte apparater fremkommer DK 170659 B1 3 således fra muligheden for ødelæggelse af eller skader på visse materialer. Hvis for eksempel kirurgiske værktøjer af metal anbringes i et mikrobølgefelt, bliver de hvidglødende og kan blive skøre, miste deres sejhed og hårdhedsegenska-5 ber og som følge heraf deres udmærkede skæreegenskaber.Thus, limitations on the use of the known apparatus arise from the possibility of destruction or damage to certain materials. For example, if metal surgical tools are placed in a microwave field, they become white-hot and can become brittle, lose their toughness and hardness properties and, as a result, their excellent cutting properties.
Formålet med den foreliggende opfindelse er at frembringe en indretning, som ved hjælp af mikrobølger kan udføre en sterilisation eller forbrænding af kirurgiske instrumenter, 10 uden at de ved sterilisationen forringes eller beskadiges, og hvor instrumenterne ved forbrændingen ødelægges uden de ulemper, som er forbundet med den ovennævnte kendte teknik.The object of the present invention is to provide a device which can, by means of microwaves, perform a sterilization or combustion of surgical instruments, 10 without being impaired or damaged during sterilization, and where the instruments of combustion are destroyed without the disadvantages associated with the prior art mentioned above.
Dette formål opnås ved en indretning af den i indledningen 15 omhandlede art, hvilken indretning ifølge opfindelsen er særegen ved, at beholderen på sin bund har et med en vandholdig væske gennemvædet lag, og at der i den for høje temperaturer egnede beholder er anbragt mineralpulver og/eller carbon, der kan forhøje temperaturen indtil en forbrænding 20 af de i beholderen opbevarede instrumenter.This object is achieved by a device of the kind referred to in the preamble 15, which device according to the invention is peculiar in that the container has on its bottom a layer soaked with a water-containing liquid and that in the container suitable for high temperatures, mineral powder and / or carbon capable of raising the temperature until a combustion 20 of the instruments stored in the container.
Laget optager mikrobølgeenergien særdeles godt og opvarmes i et sådant omfang tillige med de genstande, der ligger på det af den vandholdige væske gennemvædede lag, at de i be-25 holderen værende kirurgiske instrumenter steriliseres grundigt. Endvidere vil temperaturen gennem det i beholderen anbragte mineralpulver og/eller carbon kunne stige så meget, at instrumenter, hvor der er smittefare, kan ødelægges ved opvarmningen.The layer absorbs the microwave energy extremely well and is heated to such an extent along with the objects which lie on the water-containing liquid soaked layer that the surgical instruments contained in the container are thoroughly sterilized. Furthermore, the temperature through the mineral powder and / or carbon deposited in the container could rise so much that instruments where there is a risk of infection can be destroyed by the heating.

Den nødvendige tid ifølge den foreliggende opfindelse (test udført for eksempel af Pasteur Instituttet i Paris) er 3 minutter for 100.000 sporer, og materialet, der skal steriliseres, rammes direkte af mikrobølgerne, idet det er an-35 bragt i beholderen i et enkelt lag. Steriliseringen er derfor homogen.The required time according to the present invention (tests performed, for example, by the Pasteur Institute in Paris) is 3 minutes for 100,000 spores and the material to be sterilized is directly hit by the microwaves, placed in the container in a single layer. . The sterilization is therefore homogeneous.
DK 170659 B1 4DK 170659 B1 4
Ifølge den foreliggende opfindelse absorberer de små instrumenter, der skal ødelægges - såfremt de er af metal -straks mikrobølgerne, idet de virker som modtageantenner, der retter energien mod sig selv. De opvarmes derved til 5 det punkt, hvor de brændes til aske.According to the present invention, the small instruments to be destroyed - if they are of metal - immediately absorb the microwaves, acting as receiving antennas that direct the energy towards themselves. They are thereby heated to 5 the point where they are burnt to ashes.
De uselvstændige krav omhandler fordelagtige udførelsesfor- f mer for indretningen ifølge opfindelsen. Det er således fordelagtigt, at instrumenter med lille masse kan lægges 10 direkte på beholderens bund, som omhandlet i krav 2.The dependent claims relate to advantageous embodiments of the device according to the invention. Thus, it is advantageous that small mass instruments can be placed directly on the bottom of the container as defined in claim 2.
Foranstaltningerne i krav 3 forøger den inderlige kontakt mellem den vandholdige væske og beholderen samt de i beholderen anbragte genstande, hvorved varmeoverførslen bliver 15 yderligere forbedret. Ved foranstaltningerne i krav 3-5 udnytter man kapillarvirkningen, som sørger for, at laget af små glasperler respektivt det svampeagtige eller porøse materiale gennemvædes særligt grundigt og intensivt med den vandholdige væske.The measures of claim 3 increase the internal contact between the aqueous liquid and the container as well as the objects placed in the container, thereby further improving the heat transfer. The measures in claims 3-5 utilize the capillary action, which ensures that the layer of small glass beads or the spongy or porous material, respectively, is particularly thoroughly and intensively soaked with the aqueous liquid.

Indretningen ifølge opfindelsen forklares nærmere i det følgende under henvisning til tegningen, hvor:The device according to the invention is explained in more detail below with reference to the drawing, in which
Fig. 1 viser en indretning i form af et hus, som i sit 25 indre kan udvikle mikrobølger, hvilket mikrobølge hus kan indeholde en beholder med instrumenter, der skal steriliseres, fig. 2 viser i snit beholderen, som på bunden har et lag 30 af små perler af glas, keramik eller plast eller andet egnet materiale, fig. 3 viser i snit samme beholder opbygget af svampet } eller porøst materiale, som er i stand til at op-35 tage eller tilbageholde fordampningsegnede væsker. t'FIG. 1 shows a device in the form of a housing capable of developing microwaves within its interior, which microwave housing may contain a container of instruments to be sterilized; FIG. 2 is a sectional view of the container having on the bottom a layer 30 of small beads of glass, ceramic or plastic or other suitable material; FIG. 3 is a sectional view of the same container made of spongy or porous material capable of absorbing or retaining evaporative fluids. t '
Inden i mikrobølgehuset 1, som er forsynet med en tilgangs- DK 170659 B1 5 dør 2 og midler til regulering, styring og beskyttelse 3, er der anbragt en beholder 4 udstyret med et ikke hermetisk aflukbart låg 5.Inside the microwave housing 1, which is provided with an access door 2 and means for regulation, control and protection 3, a container 4 is provided equipped with a non-hermetically sealed lid 5.
5 Beholderen 4 er opbygget af et materiale, som er modstandsdygtigt mod høje temperaturer, såsom keramik og ildfast materiale, og bærer på sin bund 6 et lag opbygget af små perler af glas eller lignende materiale, der kan indeholde og tilbageholde en eller anden fordampningsdygtig væske, som 10 kommes deri. Alternativt kan denne beholder opbygges helt eller delvis af et svampet materiale eller et materiale af porøst form 7, forudsat at det har kapillarvirkning for at fordele mikrobølgernes termiske og elektromagnetiske energi· 15The container 4 is constructed of a material that is resistant to high temperatures, such as ceramics and refractory material, and carries on its bottom 6 a layer made up of small beads of glass or similar material which can contain and retain some evaporative liquid , which 10 comes into it. Alternatively, this container may be constructed wholly or partially of a spongy or porous 7 material, provided it has capillary action to distribute the thermal and electromagnetic energy of the microwaves
Dette lag kan være opbygget af ekspanderet plast såsom po-lyuretan eller polystyren eller af syntetiske eller naturlige hydrofile materialer, som kan absorbere væsker. Denne fordampelige væske kan bestå af vand eller en vandig opløs-20 ning med højt kogepunkt (for eksempel glykol, højere alkoholer, og så videre), eller opløsninger af organiske salte i vand, eller simple vand/alkohol opløsninger.This layer may be made of expanded plastics such as polyurethane or polystyrene or of synthetic or natural hydrophilic materials which can absorb liquids. This vaporizable liquid may consist of water or a high boiling aqueous solution (for example, glycol, higher alcohols, and so on), or solutions of organic salts in water, or simple water / alcohol solutions.
Instrumenterne, der udsættes for mikrobølger, bliver opvar-25 mede, hvilket på grund af tilstedeværelsen af fordampende væsker i beholderen modereres, fordi dampen, der dannes i beholderen, virker som beskyttelsesmiddel for materialerne, som ellers er vanskelige at sterilisere eller umulige at sterilisere på grund af risikoen for ødelæggelse, forårsa-30 get af mikrobølgernes energi.The instruments exposed to microwaves become heated, which due to the presence of evaporating liquids in the container is moderated because the vapor formed in the container acts as a protective agent for the materials which are otherwise difficult to sterilize or impossible to sterilize on. because of the risk of destruction, the spring of microwave energy.
Når der anbringes mineralpulver og/eller carbon, som er i stand til ikke alene at diffundere mikrobølgernes elektromagnetiske energi, men også forøge temperaturen væsentligt 35 i beholderen, opnås der fuldstændig destruktion af metalliske kirurgiske instrumenter såsom nåle, engangs-skalpeller og lignende genstande og følgelig også af beskyttelses- DK 170659 B1 6 hylstre, hvis de stadig findes, ved forbrænding.When mineral powder and / or carbon, capable of not only diffusing the electromagnetic energy of the microwaves, but also substantially increasing the temperature of the container, is placed, complete destruction of metallic surgical instruments such as needles, disposable scalps and similar objects is achieved. also of protective casing, if still present, by combustion.
Det er således muligt enten at sterilisere kirurgiske instrumenter og lignende grundigt eller destruere dem fuld-5 stændigt ved forbrænding, især farlige instrumenter, som kan være kilder til forurening.Thus, it is possible to either thoroughly sterilize surgical instruments and the like or to destroy them completely by incineration, especially dangerous instruments which may be sources of contamination.
