Abstract

Surgical instruments and the like are first placed in a non-sealed container which includes a material capable of absorbing a liquid. They can be placed either directly on the bottom of the said container or on a layer of such material producing vapours which saturate the environment, or are arranged in combination with a suitable material to raise the temperature up to incineration temperature. The said container is then placed in an appropriate microwave container for sterilisation or incineration of the objects contained therein.

Description

Sterilisation device and method

The present invention relates to a kind of microwave that utilizes to disinfectant equipment such as surgery equipment, reach sterilization (vanishing) purpose until the equipment relevant with risk of infection is arranged burned.

The very high frequency(VHF) microwave that utilizes a magnetron to be produced is realized the purpose of intensification, and this is known.In fact, have magnetic polarity in the chemical constitution of some material, when very high frequency electromagnetic wave acts on the material of forming with this material, can make its molecular vibration and cause heating strongly fast.

So far, the use of these equipment is limited on the civilian or specific purposes of industry, but is subjected to the restriction of its material structure.

People also know, can destroy pityrosporion ovale and virus by the synthetic mechanocaloric effect that very high frequency(VHF) produces.

Because some material might be destroyed or damage to known method, so its use is restricted.For example, as metal surgery (operation) cutter is placed microwave, it is red-hot that these cutters can become, and becomes fragile, and loses its toughness and rockiness, thereby lose its good cutting performance.

Main purpose of the present invention is, avoids above-mentioned shortcoming and a kind of equipment is provided, and promptly utilizes microwave that the sterilization of metal surgery device is not made to be damaged or damages;

Another object of the present invention is, a kind of equipment is provided, and promptly utilizes the purpose of burning deleterious especially utensil and reaching sterilization.

Consult accompanying drawing now and describe an example of the present invention.Wherein accompanying drawing is:

Fig. 1 represents a microwave generator, and it can hold a container that utensil to be sterilized is housed;

Fig. 2 represents a container with profile, and its bottom is a bed course that is made of the bead of many glass or plastics or pottery or other suitable material systems; And

Fig. 3 represents a same container with profile, and it is to form with spongy or column (trabecular) material that can hold or retain evaporating liquid.

Be provided with an access door 2 and for regulating, in the microwave box 1 of the device 3 of control and protection, being placed with a container 4 that blow-by lid 5 is housed.

This container 4 is by exotic material, makes such as pottery and refractory material, and 6 have a bed course bottom it, and it can hold or retain the glass of any evaporating liquid that is introduced into or bead that other material is done constitutes by many.Perhaps, for the heat energy and the electromagnetic energy of distributing microwave, this container also can all or part ofly be made with spongy material or cylindrical material 7, so that it has capillarity.

Described bed course can be used expansion plastic, and such as polyurethane and polystyrene, the synthetic or natural hydrophilic material that maybe can absorb liquid is made.This evaporating liquid can be by water or high boiling point aqueous solution (as ethylene glycol, higher alcohol etc.), or the organic salt aqueous solution, or simple water/alcoholic solution is formed.

The equipment that is placed in the microwave is heated; because the steam that forms in container can be protected (equipment) material; now because of existing evaporating liquid that heating is relaxed in the container; and because microwave energy will bring destructive danger, with additive method these materials of just cannot or hardly sterilizing utterly.

On the other hand; in container, insert powdered rubber; during such as mineral powder or other similar aluminium chips types or steel wool section bar material; these materials not only spread the electromagnetic energy of microwave but also have improved temperature greatly; like this; reached metal surgery (operation) utensil by burning, but such as the scalpel of entry needle disposable etc. and as the purpose of the thorough sterilization (vanishing) of the protective layer that also has.

Like this, just can or make thorough disinfection such as surgery (operation) utensil, perhaps utilize burning may be those deleterious especially utensils of the source of infection and reach the purpose of thorough sterilization (vanishing).

Claims (4)

1, a kind of equipment that utilizes microwave to sterilization usefulness such as surgery equipment, it comprises a microwave generator, it is characterized in that: comprise that also one holds the container that thing to be sterilized is used, this container comprises a kind of material that can absorb liquid; One main body and one places the packing less lid on the described main body; The inwall of described lid is made up of a kind of sponge or column material, and described main body comprises the bottom cushion that the described material of a usefulness is made.

2, equipment as claimed in claim 1 is characterized in that, described material is made up of all little solid ball, can retain the liquid that enters between the bead.

3, equipment as claimed in claim 1 is characterized in that, described material is a sponge.

4, equipment as claimed in claim 1 is characterized in that, described material is a column.
