[Prior Art] The most common and effective method for disinfecting medical devices in medical institutions is high-temperature disinfection. However, due to limitations of site and operating conditions, many medical devices cannot be used for high-temperature disinfection. In order to ensure that the contaminants and bacterial viruses in the medical process are completely removed, the patients are infected in the follow-up medical process, resulting in the loss of life and property. Decontamination, which is known in the border treatment community, includes disinfection and sterilization. Generally, it is required for various invasive or medical equipment regulations. Most of them require 2 to sterilization level. However, for many complicated heat-resistant equipment such as expensive endoscopes. When it is not possible to treat it in the usual high temperature sterilization process, the advanced mother (99.9999%) is also an acceptable alternative to the regulations. In addition to the high-temperature sterilization method, the common alternative disinfection method is more effective in disinfecting with ethylene oxide (E〇), which is mainly used for the construction of simple heat-labile medical equipment in medical institutions. Currently, the International Agency for Research on Cancer (IARC) has listed E〇 as a first-class carcinogen, and exposure to this chemical may also cause symptoms such as nausea, vomiting, skin burns or pulmonary edema; in addition, studies have shown E〇 can cause abortion and fetal abnormalities, or increase gastric cancer, white blood, and circulatory system 5 1284543 • · · . The main exposed persons in the hospital are the personnel who operate the E0 sterilizer in the disinfection room. In addition, the units that use the sterilized equipment in each unit may also be exposed to the residual equipment and gradually release the ethylene oxide. In addition, if the independent ventilation and exhaust equipment is not designed in all parts of the E0 sterilizer, the settlement of the E〇 may be retained in the workplace, causing many people's violent temper. Internationally, in response to the potential hazards of ethylene oxide to users, it is actively seeking alternative sterilization methods. Although the currently available cryo-sterilization technology 'except for Ethylene Ethylene Beverage' is also Ionizing Radiation, Gas Plasma, or VaPor phase Hydrogen Peroxide. Chemicals such as Ozone, Peracetic acid and glutaraldehyde, while considering the economic cost, disinfection effect, and the type of applicable articles, the Ethylene Ethylene Disinfection Method is still the most popular. method. For many heat-insulating materials such as expensive endoscopes, etc., currently: The commonly used low-temperature sterilization technology is mainly liquid reaction, such as chemistry such as acetic acid or glutaraldehyde. The substance soaks the endoscope for a period of time and flushes the endoscope tube through the above-mentioned drug circulation to achieve contact and eliminate bacteria and viruses. However, the common problem facing the international medical community is that expensive endoscopes have a complicated design, so that viruses adhering to pores, pipes and joints cannot be completely removed by chemical rinsing, and even many resistant bacterial spores. Can enter the hibernation state in harsh environment, once the harsh environment disappears, the uncleared bacteria can be restored to the activity of 1284543, causing the infection of the patient to die, so that the cleaning of the enamel is mutually infected, and the death case is heard; When the second medicinal agent and other medicinal agents = sex ^ = the respiratory hazard of the operator is not effective when the operation is carried out [invention content] It can be seen that the above-mentioned conventional methods still have many defects, and the design needs to be improved.

The method and device for low temperature sterilization and sterilizing which can achieve the above object are mainly various medical equipments, such as Scaling, knives, clips and expensive and complicated endoscopes, cardiac catheters, dialysis machines and other contaminated medical equipment are placed in a reaction system containing super-wave, standby, external, ozone and disinfectant. Acoustic shock can effectively desorb and remove bacterial spores, viruses or contaminants in various medical equipment surfaces, hollow tubes, joints and cracks, and then detoxify and remove bacterial spores, viruses or The oxidative destruction of organic pollutants, combined with the bactericidal power of the external line, can be achieved as a photocatalytic reaction to improve the efficiency and accelerate the destruction of ozone oxidation. At the same time, the disinfectant is also desorbed with bacterial spores, _ poison or pollution. Contact with objects and destroy them to achieve the ultimate goal of disinfection and sterilization. Many invasive winter medical equipment will stick to the patient's pollutants such as body fluids, blood, diseases: bacteria, viruses, etc. Past experience shows that the adhesion of such pollutants is strong. Without proper decontamination methods, it is very difficult to completely and completely eliminate the pollutants. Therefore, the use of ultrasonic vibration The main purpose is to effectively desorb the bacterial spores, viruses or contaminants in the surface, hollow tubes, joints and cracks of various medical chair chairs through their powerful Cavitations. 1~〇(9)khz, the pot strength is sufficient to oscillate contaminants as small as 0.12 micron pores out of the medical equipment and react with other units in the system. 1284543 , · t • -.,-. After passing air or pure oxygen through an ozone generator, a high concentration of ozone is produced, and then introduced into the bottom of the reaction tank through a conveying system and an aeration device, and fully mixed with the aqueous solution to form a saturated ozone water (〇 atedated water, which is removed by ultrasonic waves). When the contaminant is in contact with the saturated ozone in the aqueous solution, the oxidative decomposition and decomposition reaction is immediately performed, and the pollutants of the human body are all carbohydrates, which can be converted into harmless carbon dioxide and water after being decomposed by ozone, thereby achieving the effect of decontamination and disinfection. Ultraviolet light is a powerful and inexpensive disinfecting tool that can effectively destroy bacteria or viruses. The ultraviolet wavelength of this system is 100~390 nanometer (1000~3900 Angstroms), and the reaction tank forms a sterilized state under ultraviolet irradiation. Prevent bacterial viruses and viruses in the outside air from re-infection (R:econtamination); and under ozone irradiation, ozone can also undergo photochemical catalytic reaction to accelerate the decomposition rate of pollutants, which is contrary to disinfection. The bacteriostatic reaction proceeds. The aqueous solution f of the system is added with a chemical agent, and is transported from the chemical tank to the reaction tank through the pump. Through the reaction with the desorbed bacterial virus, the chemical agent can quickly kill it and achieve sterilization. The purpose. The above chemical agents refer to generally common liquid disinfectants or sterilizing agents such as: Hydrogen Peroxide, Hydrochloric acid, Sulfuric acid and Hypochlorite, etc. The range is from 10 to 200,000 ppm.
