Description

TECHNICAL FIELD [0001] The present invention relates to a medical sterilizer using chlorine dioxide gas,

The present invention relates to a medical sterilizer using chlorine dioxide gas for sterilizing a surgical instrument and a patient treatment instrument using chlorine dioxide gas.

There are 6 types of sterilizer: pressurized steam, dry heat sterilization, ultraviolet ray, plasma, EO GAS, CLO2.

First, the pressurized steam sterilizer has excellent penetration ability and is good for cotton products, but it causes rust and corrosion of metal (carbon steel) and makes the nose blade blunt. Also, there is a disadvantage that the synthetic resin is damaged, and the drying process after sterilization is separately performed.

Dry heat sterilizers are inexpensive and are good for glass, dried compounds and powder products. However, they are disadvantageous in that the sterilization time is long and the temperature is high and deformation occurs in the metallic product.

The plasma sterilizer has a disadvantage in that it is stable to the metal without rusting or corrosion, but is weak in penetration and is not suitable for a large package or a cotton product.

Such a plasma sterilizer is disclosed in Korean Patent Laid-Open Publication No. 10-2009-0103376, which discloses a plasma sterilizer having a magnetron for generating high-frequency electromagnetic waves, a reaction chamber in which high frequency electromagnetic waves generated from the magnetron and a gas for generating active oxygen are introduced, A launcher in which one end is connected to the magnetron and the other end is connected to the reaction chamber to guide the high frequency electromagnetic wave generated from the magnetron to the reaction chamber so that oxygen is introduced into the reaction chamber; A high frequency electromagnetic wave permeable membrane provided between the other end of the launcher and the reaction chamber so as to spatially block the launcher and the reaction chamber and to transmit high frequency electromagnetic waves generated from the magnetron, The electromagnetic wave flows into the sterilization chamber And a vacuum pump connected to the sterilizing chamber so as to generate a plasma, wherein the high-frequency electromagnetic wave blocking unit is disposed between the reaction chamber and the sterilizing chamber so as to block the reaction chamber and the reaction chamber, .

However, in the above-described plasma sterilizer, the sterilized object to be sterilized is directly brought into contact with the plasma, and thus the medical instrument of the polymer system tends to cause a change in properties such as discoloration or material hardening .

And EO GAS sterilizer is good for rubber products and it is suitable for large sized hospital but it has a disadvantage that sterilization time is very long, ventilation is required after sterilization day, toxic and carcinogenic substances are included, which makes handling very difficult.

In this way, the sterilizer used for the prevention of infectious diseases and the sterilization of pathogens in hospitals and medical facilities is an absolutely necessary product for sterilization of most medical equipment used in the hospital's operating room or through thorough sterilization management of disposable products to be.

In such a method, the time required for the sterilization and deodorization treatment becomes long, and frequent reuse is impossible. Attempting to use a complicated cleaning device requires a great deal of cost.

There is a demand for a sterilizing device that can sterilize and deodorize these medical instruments safely, easily, and reliably.

An aqueous solution or gas of chlorine dioxide is known as a highly suitable medium for sterilization and deodorization treatment. It has long been known that chlorine dioxide has strong bleaching action, and many manufacturing methods have been proposed.

The chlorine dioxide gas which vaporizes the stabilized chlorine dioxide aqueous solution exhibits various effects such as high sterilization, deodorization and disinfection by contact with the object while being safe because there is no intense irritating odor.

The effects of sterilization and sterilization of various viruses, bacteria, fungi, and hospital fungi are remarkable, and the object can be achieved in a short time. In addition, the deodorizing effect is strong, and the deodorizing effect on the smell of chemical substances and the smell of corruption is exhibited.
