Problems solved by technology

But ClO 2 Unstable, easy to decompose when heated or exposed to light, usually in the form of an aqueous solution for disinfection of water and the surface of objects
[0003] Among the low-temperature sterilization methods currently used in the medical field at home and abroad, some have the problems of long sterilization time and chemical residues after sterilization, and some have insufficient diffusion and penetration capabilities, and are not effective in sterilizing long and thin catheter devices. The length of the bacteria is limited, and the volume of the sterilization room is small, which cannot adapt to the rapid sterilization of a large number of items; at the same time, in order to ensure the vaporization of the sterilization medium, the temperature of the sterilization needs to be controlled above 50-65°C, or even higher , cannot be used at room temperature (15-25°C)

Embodiment 1

[0028] In this example, chlorine dioxide gas and plasma room temperature sterilization devices include:

[0029] Such as figure 1 As shown, a barrel-shaped sterilization cabin 1 that is airtight and can form a negative pressure made of stainless steel, a sealing device with a locking sealing device 1-1 (the sealing device is equipped with a silicone rubber sealing ring) is installed on one side of the cabin body. The door 1-2 and the sterilization chamber 1 are connected to the vacuum pump 1-6 through the negative pressure pipeline 1-5 and the control valve i (F1).

[0030] Two instrument storage boxes 2 made of stainless steel or aluminum alloy sheets that can hold items to be sterilized. The instrument storage boxes are placed on the double-layer shelves 1-3 in the sterilization cabin, and one end of the air inlet port 2- 1 is connected to the reaction chamber 3 through the sterilization medium inflation port 1-4 of the sterilization bulkhead, the control valve iv (F4) and ...

Embodiment 2

[0043] The device of this embodiment is basically the same as that of Embodiment 1, the only difference being that the sterilization cabin 1 is made of aluminum alloy material, and both sides of the sterilization cabin are equipped with airtight doors 1-2, and are locked and sealed. The device 1-1 is electronically or mechanically interlocked and cannot be opened at the same time. There are three layers of shelves 1-3 inside the airtight cabin. The instrument storage box 2 is made of silicone resin material. The reaction chamber 3 is made of stainless steel, the reaction solution 3-7 is an aqueous solution of citric acid, the solid raw material storage box 3-2 is composed of 12-16 small compartments, and the reaction raw materials 3-8 are sodium chlorite and Catalyst Calcium Chloride. The pressurized chamber 4-3 is sealed and fed with compressed air for pressurization, so that the neutralizer passes through the elbow and the nozzle (4-7) to form water mist in the neutralized ...

Embodiment 3

[0052] The device of this embodiment is basically the same as that of Embodiment 1, the only difference is that the sterilization chamber 1 is made of aluminum alloy material, and a sealed door 1-2 is installed on one side of the sterilization chamber, and there is only 1 inside the sealed chamber. Shelves 1-3. Instead of using an instrument storage box, use a sterile bag with an antibacterial filter to seal the instrument and place it on the shelf. The reaction chamber 3 is made of stainless steel, the reaction liquid 3-7 is water, the solid raw material storage box 3-2 is composed of 20 small compartments, and the reaction raw material 3-8 is a two-component: group A sodium chlorite And group B citric acid and calcium chloride.

[0053] The sterilization treatment method of this example comprises the following steps:

[0054] 1) Make the sterilization chamber 1 reach a negative pressure of 50-80Pa through the vacuum pump 1-6;

[0055] 2) Add the reaction solution 3-7 and ...

Abstract

The invention relates to a chlorine dioxide gas and plasma room temperature sterilizing device and a sterilizing method thereof. The technical problem to be solved by the invention is to provide the sterilizing device and the sterilizing method capable of dried sterilization in an environment at room temperature of between 15 and 25 DEG C. The technical proposal to solve the problem comprises that the device comprises an airtight sterilizing cabin which can form negative pressure, a group of equipment storage cases or sterilized package bags, an air filter, a reaction chamber, a smoke absorber and a plasma excitation source, wherein, one or two sides of the cabin body is / are provided with an sealing door with a locked seal device; the equipment storage cases or the sterilized package bags can hold objects to be sterilized; the air filter is provided with a sterilizing filter element; and the reaction chamber can generate a sterilizing medium. The device and the method are mainly used for performing quick sterilizing treatment on various high temperature intolerance medical devices, biologic test appliances, pharmacy tools and objects at room temperature.

Description

technical field [0001] The invention relates to a medical sterilization device and method, in particular to a chlorine dioxide gas and plasma room temperature sterilization device and a sterilization method, which are mainly used for various medical devices, biological test supplies, and pharmaceutical appliances that cannot withstand high temperatures. and items are subjected to rapid sterilization at room temperature. Background technique [0002] Chlorine dioxide (ClO 2 ) as a strong oxidizing agent with a low dosage, it can kill all microorganisms, and has the characteristics of high efficiency, broad spectrum, fast, long-lasting, safe, non-residue and non-toxic. But ClO 2 Unstable, easy to decompose when heated or exposed to light, usually in the form of an aqueous solution for disinfection of water and the surface of objects. [0003] Among the low-temperature sterilization methods currently used in the medical field at home and abroad, some have the problems of lon...
