The sterilized medical equipment and various equipments are placed in a sterilization chamber and air As it completely sterilizes by supplying ozone in a circulating manner, it can maximize disinfection and sterilization efficiency, and it is hygienic and stable by suppressing secondary infection and fungus growth. Ozone is inhaled by circulating It is possible to protect human health by preventing harm, to eliminate discomfort caused by the smell of ozone, and to reduce residual air pollution, and to remove residual ozone, which contributes to improving global warming. will be.
Description
The present invention relates to a circulating plasma sterilizer which is easy to remove residual ozone, and more particularly, sterilization of fungi present in a sterilized object such as a medical device by using ozone generated by the operation of a plasma ozone generator. The present invention relates to a circulating plasma sterilizer capable of easily removing residual ozone to remove ozone remaining in the sterilization process with a photocatalyst plasma lamp through a circulation method.
In general, various types of disposable medical tools or reusable medical tools used in a medical institution such as a hospital should be maintained in a sterile state before use. Therefore, various methods for sterilizing such medical tools have been developed. Such sterilization methods include a conventional method using high temperature and high pressure, a method using ethylene oxide gas, a method using hydrogen peroxide plasma, and the like.
The traditional method using high temperature and high pressure has a problem in that it does not completely sterilize the microorganisms present in the sterilized products, and the method using ethylene oxide gas uses CFC gas, which is the main cause of global environmental pollution, as a carrier gas. There was a discomfort that could cause seriously, and additionally a long aeration time to remove the remaining ethylene oxide after sterilization treatment.
On the other hand, the method using hydrogen peroxide plasma is a method of generating and sterilizing the plasma while maintaining the inside of the reaction vessel at a pressure lower than atmospheric pressure, so the structure of the apparatus is complicated, and the size of the apparatus is increased. Since the temperature rises to a high temperature of 50 ℃ or more, there is a problem unsuitable for sterilization of the tool of the plastic material.
In addition, the time required for disinfection in the case of autoclave sterilization and EO (Ethlene Oxide) gas sterilizer that is currently spreading is usually 1 to 3 hours in case of autoclave sterilization, 8 to 12 hours in case of EO gas disinfection As a result, this not only causes human and time waste, but also causes inefficiency in equipment operation, and also has a problem of sterilizing with various sterilizers because the disinfection methods are different for each equipment.
In addition, the conventional apparatus for disinfection using plasma is a situation in which the sterilization and sterilization is not performed because low-temperature plasma or ozone, which is disinfection gas, does not reach deep inside the object to be disinfected, that is, inside the pipe or pipe.
The present invention is to sterilize the medical equipment and various equipment to be sterilized in the sterilization chamber and supply ozone in the air circulation method to completely sterilize, so as to maximize the disinfection and sterilization efficiency to suppress secondary infection and fungal growth As it is stable in hygiene, the residual ozone after sterilization is circulated through photocatalytic plasma lamp and ozone filter to safely remove ozone and prevent human body health by preventing ozone from inhaling and harming respiratory organs. The purpose of the present invention is to provide a circulating plasma sterilizer capable of eliminating the discomfort felt according to the removal of residual ozone, which contributes to the improvement of global warming by reducing air pollution.
The present invention for achieving the above object is a plasma sterilizer equipped with a main body is provided with a sterilization chamber to accumulate the sterilized target therein, and a plasma generator for generating ozone to sterilize the sterilized target, It is installed to open and close the sterilization chamber, the door formed with a tempered glass window to check the sterilization chamber from the outside, the storage unit formed in multiple layers to evenly sterilize the sterilization target inside the sterilization chamber, so that the air of the sterilization chamber to escape A suction port to be formed, a blower installed in the suction port to forcibly suck air from the sterilization chamber, a transfer pipe for transferring the air sucked into the blower, and a plasma ozone generator connected to the transfer pipe to generate ozone during sterilization time Wake out, consisting of a transfer pipe for transferring the ozone generated in the plasma ozone generator to the sterilization chamber And a discharge port formed to introduce ozone generated in connection with the transfer pipe into the sterilization chamber, a blower installed at the suction port to forcibly suck air in the sterilization chamber, a transfer pipe for transferring the air sucked into the blower, and Ozone removal unit consisting of a ozone removal device for removing the ozone of the air introduced from the sterilization chamber during the ozone removal time connected to the transfer pipe, and a transfer pipe for transferring the air from which ozone is removed from the ozone removal device to the sterilization chamber, the transfer pipe A discharge port which is connected to and connected to the sterilization chamber to remove the ozone-removed air, and is provided at an upper end of the main body, and includes a control unit provided to control ON / OFF of the sterilization unit and the ozone removal unit. The ozone removal unit is interlocked to provide a circulating plasma sterilizer that is easy to remove residual ozone that is mutually exclusive.
The present invention is to sterilize the medical equipment and various equipment to be sterilized in the sterilization chamber and supply ozone in the air circulation method to completely sterilize, so as to maximize the disinfection and sterilization efficiency to suppress secondary infection and fungal growth As it is stable in hygiene, the residual ozone after sterilization is circulated through photocatalytic plasma lamp and ozone filter to safely remove ozone and prevent human body health by preventing ozone from inhaling and harming respiratory organs. It can eliminate the discomfort that is felt along the way, and it is very useful to contribute to the improvement of global warming by reducing air pollution.
