E conhecido que a geraçao de microí! -ondas de frequência muito elevada por um magnetrao atinge ; os objectivos da elevaçao de temperatura. De facto as ondas , e1ectrornagneticas de frequência muito elevada actuam sobre ! os materiais constituídos por substâncias que possuem polaridade magnética na sua estrutura química provocando vibrações meleculares que provocam um aquecimento forte rápido.It is known that the microí generation! - very high frequency waves by a magnetron reaches; the objectives of temperature rise. In fact the waves, electronagneticas of very high frequency act on! materials made up of substances that have magnetic polarity in their chemical structure causing melecular vibrations that cause rapid rapid heating.

A utilização de tais sistemas têm-se restringido, ate ao presente, a aplicações industriais ou jdomesticas ou aplicações especiais, mas com limitações derivaj das da estrutura do proprio material, iiThe use of such systems has been restricted, until now, to industrial or domestic applications or special applications, but with limitations derived from the structure of the material itself, ii

Ê também conhecido que as bactérias e virus esporogenicos sao destruídos por combinação do efeito i mecânico e térmico provocado por frequências muito elevadas.It is also known that sporogenic bacteria and viruses are destroyed by combining the mechanical and thermal effect caused by very high frequencies.

As limitações a utilização dos procedimentos conhecidos resultam da possibilidade de deterioraçãoThe limitations to the use of known procedures result from the possibility of deterioration

ou danos provocado a certos materiais. Por exemplo, se se colocam instrumentos cirúrgicos de metal afiados num micro-ondas, eles tornam-se incandescentes e podem tornar-se fregeis, perdendo as suas propriedades de resistência e dureza e como consequência as suas excelentes capacidades de corte.or damage to certain materials. For example, if sharp metal surgical instruments are placed in a microwave, they become incandescent and can become brittle, losing their strength and hardness properties and as a consequence their excellent cutting capabilities.

objectivo principal da presente invenção é o de evitar a desvantagem anteriormente mencionada e proporcionar um método e um equipamento que, por meio de um ! micro-ondas, proporcione uma esterilização dos instrumentos cirúrgicos de metal sem deterioração ou danos.main objective of the present invention is to avoid the aforementioned disadvantage and to provide a method and equipment which, by means of a! microwave, provide sterilization of metal surgical instruments without deterioration or damage.

Outro objectivo da presente invenção * é o de proporcionar um método e um equipamento que possa desj truir por incineração instrumentos particularmente perigosos.Another objective of the present invention * is to provide a method and equipment that can destroy particularly dangerous instruments by incineration.

í j Um exemplo desta invenção vai agora j ser descrito com referência aos desenhos que a acompanham,íj An example of this invention will now be described with reference to the accompanying drawings,

I nos quais:I in which:

íí

A Figura 1 apresenta o gerador de microondas capaz de conter um recipiente com instrumentos que se destinam a ser esterilizados.Figure 1 shows the microwave generator capable of containing a container with instruments that are intended to be sterilized.

j A Figura 2 apresenta em secção transverj sal o recipiente que possui na sua base uma camada de pequenas i’ bolas de vidro ou plestico ou cerâmica ou outro material adequli !j ado.Figure 2 shows in cross-section the container that has at its base a layer of small glass or plastic or ceramic balls or other suitable material.

I j A Figura 3 apresenta em secção transver! sal o mesmo recipiente construído de material esponjoso ou ; trabeculado capaz de incorporar ou reter líquidos voláteis.I j Figure 3 shows in cross section! salt the same container made of spongy material or; trabecular capable of incorporating or retaining volatile liquids.

Dentro da câmara de micro-ondas 1,Inside the microwave chamber 1,

I ; que se proporciona com uma porta de acesso a e meios para regulaçao, protecção e controlo 3, coloca-se um recipiente ! A, equipado com uma cobertura nao velada 5.I; that comes with an access door and means for regulation, protection and control 3, a container is placed! A, equipped with an unveiled cover 5.

J 0 recipiente A e construído de material j resistente a temperaturas elevadas, tal como material cerâmico e refrastário, e possuindo na sua base 6 uma camada construída com pequenas bolsas de vidro ou outro material capaz de incorporar e reter qualquer líquido voláteis que se introduza.Container A is constructed of material already resistant to high temperatures, such as ceramic and refractory material, and having at its base 6 a layer constructed with small pockets of glass or other material capable of incorporating and retaining any volatile liquids that are introduced.

. Alternativamente este recipiente pode ser construído totalmente i!. Alternatively, this vessel can be built entirely i!

íí ou em parte de material esponjoso ou um material de forma trabeculada 7, desde que ele seja capaz de produzir capilaridade de modo a distribuir a energia térmica e electromagnetica do micro-ondas.1 or partly of spongy material or a trabecular shape material 7, provided that it is capable of producing capillarity in order to distribute the microwave thermal and electromagnetic energy.

| A referida camada pode ser construída de plásticos explandidos tais como poli-uretano e poli-estireno , ou de materiais hidrofilícos sintéticos ou naturais que ! sejam capazes de absorver líquidos. Este liquido ebuliente pode ser constituído por agua ou uma solução aquosa de ponto de ebulição elevado (por exemplo, glicois álcoois superiores, etc.), ou soluçoes de sais orgânicos em agua, ou simples soluções de água/alcool.| Said layer may be constructed of expanded plastics such as polyurethane and polystyrene, or of synthetic or natural hydrophilic materials which! are able to absorb liquids. This boiling liquid can consist of water or an aqueous solution with a high boiling point (for example, higher glycol alcohols, etc.), or solutions of organic salts in water, or simple water / alcohol solutions.

Os instrumentos expostos ao micro-ondas sao submetidos a aquecimento, o qual na presença de líquidos voláteis dentro do recipiente, é moderado devido a que o vapor que se forma dentro do recipiente actua como um meio de protec| çao para os materiais que sao, de outro modo, difícies de ιThe instruments exposed to the microwave are subjected to heating, which in the presence of volatile liquids inside the container, is moderated because the steam that forms inside the container acts as a means of protection | for materials that are otherwise difficult to

esterilizar ou absolutamente impossíveis de esterilizar devido ao risco de deterioração provocado pela energia do micro-ondas.sterilize or absolutely impossible to sterilize due to the risk of deterioration caused by microwave energy.

\ Quando, por outro lado, substâncias | em po tais como pos minerais ou outros materiais semelhantes ji do tipo de fragmentos de alumínio ou la de aço que sao capazes 1 nao só de difundir a energia electromagnetica do micro-ondas j mas também de aumentar enormemente a temperatura, sao colocados j no recipiente, consegue-se a destruição completa dos instrumentos cirúrgicos de metal tais como agulhas, bisturis descartáí ί veis e analogos e consequentemente de quaisquer revestimentos de protecção se ainda presentes, por incineração.\ When, on the other hand, substances | powder such as mineral powders or other similar materials ji type aluminum fragments or her steel that are capable 1 not only diffuse electromagnetic energy of microwave j but also greatly increasing the temperature, are already placed in the container , complete destruction of metal surgical instruments such as needles, disposable scalpels and the like is achieved and consequently any protective coatings if still present, by incineration.

íí Assim é possível quer a esterilização ;ide instrumentos cirúrgicos e analogos completamente ou a destruição completa, por incineração, de instrumentos particularjmente perigosos que sao fonte de possivel contágio.Thus it is possible to either sterilize, go through surgical instruments and analogs completely or completely destroy, by incineration, particularly dangerous instruments that are the source of possible contagion.
