Description

HYDROGEN PEROXIDE STERILIZATION SYSTEM FOR STERILIZATION OF SANITATION FACILITY

The inventive concept relates to a sterilization system for sterilization of internal air of a sanitation facility such as a GMP facility or a hospital operating theater which is called by 'operating room' where an operation is performed for a patient, and the variety of equipment such as surgical apparatuses equipped in the sanitation facility, especially, relates to a hydrogen peroxide sterilization system to safely sterilize internal air and equipment in a sanitation facility, thereby effectively sterilizing microbes, bacteria, molds, and so on.

A sanitation facility such as a hospital operating theater or a production facility certified by GMP (Good Manufacturing Practice), HACCP (Hazard Analysis and Critical Control Point), KOSHER, and so on is required strict sanitation.

Sterilization means aseptic state in which every species of microbes (bacillus, virus, fungi, etc.) including spores is completely removed, and disinfection is to remove infection and proliferation by destroying or weakening vital energy of microbes.

In special, an infection accident may be occurred in a sanitation facility such as a hospital operating theater where an operation is performed for a patient if sanitation environment is not preserved sufficiently.

Thus the hospital operating theater should preserve sterilized state in which disease-causing germs or other microbes are absolutely not exist, and it should not be allowed that a microbe approaches to a special region such as an operating region.

An operative infection occurred in a hospital is an infection that occurs by attacking a patient's body with disease-causing germs during operation. If instruments is used without sufficient sterilization, fatal infectious bacteria infects incised tissue, muscle, muscle membrane or cells to cause serious problems such as inflammation.

According to the Korea consumer agency, the operative infection is most common case accounted for 65.5% from total hospital infection.

In special, despite that surgical instruments as well as internal air of a hospital operating theater should be sterilized because an aged patient, an obese patient, a glycosuria patient, and so on who has lost immunity, is relatively weak from infection. It is an actuality that a lot of surgical instruments are reused in an operation after performing low level disinfection, and infection caused by insufficient sterilized surgical instruments makes a needless circumstance which forces to put an antibiotic. In the worst, a patient may be died caused by postoperative infection.

However, sanitation management of hospital operating theater is not sufficiently implemented in most of small and medium hospitals because of burden of cost and manpower for sterilization.

In special, it is actuality that some small and medium hospitals just disinfect and reuse surgical instruments which should be used after sterilization without securing manpower or equipment for sanitation management of the hospital operating theater. The sterilization cannot be performed to internal air of the hospital operating theater or installed equipment.

In addition, there are the problem that the sanitation management is actually difficult for a lot of hospital operating theaters in a hospital using a lot of hospital operating theaters.

Conventional medical sterilization systems for sterilizing surgical instruments are classified into six types by method, such as pressure steam, dry sterilization, UV, plasma, EO GAS, ClO₂.

The pressure steam method is superior in infiltration and useful to cotton products, but there are demerits that it causes rust or erosion of metal (carbon steel) and should be performed additional dry process after sterilization.

Further, the dry sterilization is cheap and applicable to glass, dry compound, powder product, and so on, however the dry sterilization has weakness that a metal product can be metamorphosed by long sterilization time and high temperature.

The plasma method is stable without generating rust or erosion, however, has weakness inappropriate to a large package or a cotton product because of weak infiltration.

The EO GAS method is useful to a rubber product and appropriate to a large hospital, however, has weakness of handling embarrassment because sterilization time is very long, ventilation needs for a day after the sterilization and toxic or carcinogenic material is included.

The ClO₂ gas gasified from stable ClO₂ aqueous solution is safe without simulative smell, and is in contact with a target to show various effect such as high disinfection, deodorization and decontamination.

On the other hand, strict sterilization should be required to the variety of sanitation facilities including the hospital operating theater, however, sterilization is not implemented sufficiently and there is a problem that sanitary administration is not applied to a lot of sanitation facilities systematically.

These conventional arts requires careful management because of using sulfuric acid undiluted solution and sodium chlorite undiluted solution, and requires a generator for generating chlorine dioxide gas using a gas reactor and a vacuum pump as well as various chambers such that cost is relatively high and structure is complex and a technical engineer should be required.
