Description
Korte aanduiding: SteriLisatie-inrichting en -werkwijze.Short designation: Sterilization device and method.
Deze uitvinding heeft betrekking op een werkwijze en apparatuur voor de sterilisatie van chirurgische instrumenten en dergelijke door middel van een geschikte microgolfhouder tot de vernietiging door verbranding van instrumenten waarbij een besmettingsrisico behoort.This invention relates to a method and equipment for the sterilization of surgical instruments and the like by means of a suitable microwave container to destruction by combustion of instruments involving a risk of contamination.
Het is bekend dat de opwekking van zeer hoogfrequente microgolven door een magnetron het doel van het verhogen van de temperatuur bereikt. In feite veroorzaken hoogfrequente electromagnetische golven, die inwerken op materialen die bestaan uit stoffen die magnetische polariteit in hun chemisch structuur hebben, moleculaire trillingen die sterke snelle verwarming opwekken.It is known that the generation of very high frequency microwaves by a microwave achieves the purpose of increasing the temperature. In fact, high-frequency electromagnetic waves, which act on materials consisting of substances that have magnetic polarity in their chemical structure, cause molecular vibrations that generate strong rapid heating.
Het gebruik van dergelijke systemen is tot nu toe beperkt tot industriële of thuistoepassingen of tot speciale toepassingen, maar met beperkingen die stammen van de structuur van het materiaal zelf.The use of such systems has hitherto been limited to industrial or home applications or to special applications, but with limitations inherent in the structure of the material itself.
Het is ook bekend dat sporenvormende bacteriën en virussen worden vernietigd door het gecombineerde mechanisch en termisch effect dat door zeer hoge frequenties wordt veroorzaakt.Spore-forming bacteria and viruses are also known to be destroyed by the combined mechanical and thermal effect produced by very high frequencies.
Beperkingen op het gebruik van bekende procedures zijn het gevolg van de mogelijkheid van verslechtering of beschadiging die van of aan zekere materialen wordt veroorzaakt. Indien bijvoorbeeld metalen chirurgische gereedschappen in een microgolfveld worden geplaatst, beginnen ze te gloeien en kunnen ze broos worden, waardoor ze hun onbuigzaamheids- en hardheidseigenschappen verliezen en als een gevolg daarvan hun uitstekende snijmogelijkheden.Limitations on the use of known procedures result from the possibility of deterioration or damage caused to or from certain materials. For example, if metal surgical tools are placed in a microwave field, they begin to glow and become brittle, losing their rigidity and hardness properties and, as a result, their excellent cutting capabilities.
Het hoofddoel van deze uitvinding is het bovengenoemde nadeel te vermijden en te voorzien in een werkwijze en apparatuur die door middel van microgolven voorzien in sterilisatie van de metalen chirurgische instrumenten zonder verslechtering of beschadiging.The main object of this invention is to avoid the above drawback and to provide a microwave method and equipment which provides sterilization of the metal surgical instruments without deterioration or damage.
Een ander doel van deze uitvinding is om te voorzien in een werkwijze en apparatuur die door verbranding bijzonder gevaarlijke instrumenten kunnen vernietigen.Another object of this invention is to provide a method and equipment which can destroy particularly dangerous instruments through combustion.
Een voorbeeld van de uitvinding zal nu onder verwijzing naar de begeleidende tekening worden beschreven, waarin: figuur 1 de microgolfgenerator laat zien, die een houder met te steriliseren instrumenten kan bevatten; figuur 2 in dwarsdoorsnede de houder met op de basis ervan een laag balletjes van glas of plastic of keramiek of ander geschikt materiaal laat zien; en figuur 3 in dwarsdoorsnede dezelfde houder laat zien, die is opgebouwd van sponzig of trabeculair materiaal dat verdampbare vloeistoffen kan opnemen of vasthouden.An example of the invention will now be described with reference to the accompanying drawing, in which: Figure 1 shows the microwave generator which can contain a container of instruments to be sterilized; Figure 2 shows in cross section the container with on its base a layer of balls of glass or plastic or ceramic or other suitable material; and Figure 3 is a cross-sectional view of the same container constructed of spongy or trabecular material capable of receiving or retaining vaporizable liquids.
Binnen microgolfkamer 1, die is voorzien van een toegangsdeur 2 en middelen voor regeling, bediening en beveiliging 3, is een houder 4 geplaatst, die is uitgerust met een niet-afgedicht deksel 5.Within the microwave chamber 1, which is provided with an access door 2 and means for control, operation and security 3, a holder 4 is placed, which is equipped with an unsealed cover 5.
De houder 4 is vervaardigd van materiaal dat bestand is tegen hoge temperaturen, zoals keramiek en vuurvast materiaal, en op de basis 6 ervan een laag draagt, die is opgebouwd uit balletjes van glas of ander materiaal dat welke verdampbare vloeistof dan ook, die wordt ingebracht, kan opnemen en vasthouden. Alternatief kan deze houder geheel of gedeeltelijk zijn opgebouwd uit sponzig materiaal of materiaal van trabeculaire vorm 7, vooropgesteld dat dit capillariteit kan voortbrengen, teneinde de termische en electromagnet!sche energie van de microgolven te verdelen.The container 4 is made of high temperature resistant material, such as ceramic and refractory material, and bears a layer on its base 6, which is composed of balls of glass or other material that any vaporizable liquid is introduced , can record and hold. Alternatively, this container may be constructed in whole or in part from spongy material or material of trabecular shape 7 provided it can produce capillarity in order to distribute the thermal and electromagnetic energy of the microwaves.
De genoemde Laag kan zijn opgebouwd uit geëxpandeerde kunststoffen, zoals polyurethaan en polystyreen, of uit synthetische of natuurlijke hydrofiele materialen die vloeistof kunnen absorberen. Deze kookbare vloeistof kan bestaan uit water of een oplossing in water met hoog kookpunt Cb.v. glycolen, hogere alcoholen, enz.), of oplossing van organische zouten in water, of eenvoudige water/alcoholoplossingen.The said layer may be constructed from expanded plastics, such as polyurethane and polystyrene, or from synthetic or natural hydrophilic materials that can absorb liquid. This boilable liquid may consist of water or a high boiling water solution Cb.v. glycols, higher alcohols, etc.), or solution of organic salts in water, or simple water / alcohol solutions.
De aan de microgolven blootgestelde instrumenten worden onderworpen aan verwarming, die in de aanwezigheid van verdampbare vloeistoffen binnen de houder wordt gematigd, omdat de damp die binnen de houder wordt gevormd, werkt als een beveiligingsmiddel voor de materialen die anders moeilijk zijn te steriliseren of absoluut onmogelijk zijn te steriliseren ten gevolge van de verslechteringsrisico's die worden veroorzaakt door de energie van de microgolven.The instruments exposed to the microwaves are subjected to heating, which is moderated in the presence of evaporable liquids inside the container, because the vapor generated inside the container acts as a safeguard for the materials that are otherwise difficult to sterilize or absolutely impossible can be sterilized due to the deterioration risks caused by the energy of the microwaves.
Wanneer anderzijds poedervormige stoffen zoals mineraalpoeders of andere gelijksoortige materialen van de aluminiumfragmenten of het staalwoltype die niet alleen de electromagnetische energie van de microgolven kunnen verspreiden maar eveneens aanzienlijk de temperatuur verhogen, in de houder worden geplaatst, wordt volledige vernietiging van metalen chirurgische instrumenten, zoals naalden, wegwerpscalpels en dergelijke, en dientengevolge van welke beschermingsomhulsels dan ook, indien die nog steeds aanwezig zijn, door verbranding wordt bereikt.On the other hand, when powdered substances such as mineral powders or other similar materials of the aluminum fragments or the steel wool type that can not only dissipate the electromagnetic energy of the microwaves but also significantly increase the temperature are placed in the container, complete destruction of metal surgical instruments, such as needles , disposable scalpels and the like, and consequently any protective casings, if still present, are achieved by combustion.
Aldus is het mogelijk hetzij chirurgische instrumenten en dergelijke grondig te steriliseren, hetzij bijzonder gevaarlijke instrumenten, die bronnen van mogelijke besmetting zijn, volledig te vernietigen door verbranding.Thus, it is possible to either thoroughly sterilize surgical instruments and the like, or completely destroy particularly dangerous instruments, which are sources of possible contamination, by burning.
Samenvattend heeft de uitvinding betrekking op een werkwijze en apparatuur voor het steriliseren van chirurgische instrumenten en dergelijke, waarbij de te steriliseren objecten eerst in een niet-afgedichte houder worden geplaatst, die is voorzien van een materiaal dat vloeistof kan absorberen. De objecten kunnen hetzij direct op de bodem van de genoemde houder worden geplaatst, hetzij op een laag van dergelijk materiaal dat dampen voortbrengt die de omgeving verzadigen, of worden in combinatie met een geschikt materiaal ingericht om de temperatuur te verhogen tot de vernietiging door verbranding van instrumenten waaraan een besmettingsrisico kleeft. De genoemde houder wordt dan in een geschikte microgolfhouder geplaatst voor sterilisatie of verbranding van de daarin opgenomen objecten.In summary, the invention relates to a method and equipment for sterilizing surgical instruments and the like, wherein the objects to be sterilized are first placed in an unsealed container which is provided with a material that can absorb liquid. The objects can be placed either directly on the bottom of the said container, or on a layer of such material that produces vapors that saturate the environment, or are arranged in combination with a suitable material to increase the temperature to destruction by combustion of instruments with a risk of contamination. The said container is then placed in a suitable microwave container for sterilization or combustion of the objects contained therein.
