Description

Medical Instrument Sterilizers Using OH Radicals

It is an object of the present invention to provide a method for providing a medical instrument sterilizer using OH radicals.

Many medical instruments, except disposable medical instruments, have been used for sterilization and disinfection, either high temperature (hot, high pressure steam or dry heat) or toxic chemicals (ethylene oxide, propylene oxide, formaldehyde, etc.). Sterilization methods using high pressure steam do not take much time, are inexpensive and have high efficiency. However, in the medical environment, the frequency of use of instruments that can be damaged by heat is increasing, and even those that are resistant to heat have a disadvantage of shortening their lifespan, and the scope of application of autoclave sterilization at high temperatures is being reduced. There is an increasing need for methods of sterilization at low temperatures.

The most common method of sterilizing heat sensitive instruments at low temperatures is through the use of chemical gases. The chemical sterilization method includes a preconditioning process, a sterilization gas injection process, a process of exposing the object to the sterilization gas for a predetermined time, a sterilization gas removal process, an internal air purification process and the like.

Representative of such low temperature sterilization method is a method using EO (Ethylene Oxide) Gas. EO (Ethylene Oxide) gas is not only a highly dangerous substance such as carcinogenicity and neurotoxicity, but also a flammable and explosive substance, and is used to reduce the risk of explosion by mixing CFC (Chlorofluorocarbon). Chlorofluorocarbon (CFC) is a representative gas of greenhouse gases and a hazardous substance. This risk necessitates a process of removing toxic gases remaining in the medical device by continuous aeration after sterilization.

Therefore, the time required for disinfection is a short time of about 1 to 3 hours, but the time required to wait until the sterilized medical apparatus can be used requires about 14 to 36 hours. In addition, in order to sterilize a large amount of instruments, a large amount of sterilization chamber is required or a separate ventilation space is required, and inefficient problems such as the long time required to use the apparatus put into the sterilization process have.

In order to solve this problem, hospitals that require many medical devices are equipped with several sets of the same kind of medical devices, and the cost is very large. In addition, since sterilizers using ethylene oxide (EO) gas are expensive, there are many economic difficulties in purchasing sterile sterilizers using ethylene oxide (EO) gas in small hospitals.

The present invention is to solve the above problems, and to provide an apparatus for sterilizing and sterilizing medical instruments efficiently, more specifically by using OH (hydroxyl radical) radicals, without using high temperature and high pressure, It is aimed at providing a method of increasing the effectiveness of sterilization and reducing the time and cost required.

In order to achieve the above object, the present invention provides a) a storage tank for storing water, b) a water supply port for supplying water stored in the storage tank, and c) an OH (hydroxyl group) radical generator for generating OH (hydroxyl group) radicals, and d) An inlet for injecting OH (hydroxyl) radicals generated from the OH (hydroxyl group) radical generator and e) OH (hydroxyl group) injected from the water supplied from the reservoir and the OH (hydroxyl) radical generator for disinfection of a medical device A) a sterilizing disinfecting unit for mixing radicals and containing the mixed solution; and f) a drain hole for discharging the mixed liquid used for disinfection; It is characterized by.

In addition, in the present invention, the storage tank and the OH (hydroxyl radical) generating unit is characterized in that coupled to the sterile sterilization center.

In addition, in the present invention, it is characterized in that it comprises a first sensor which is attached to one surface of the sterilization sterilization unit can measure the water level.

And, in the present invention, it is characterized in that it comprises a second sensor that is attached to one surface of the sterilization sterilization unit can measure the water level.

Disinfection method of medical instruments using OH (hydroxyl) radicals according to the present invention does not use a high pressure sterilizer using a high temperature and high pressure, thereby reducing the time required for sterilization and the existing expensive EO (Ethylene Oxide) gas By not using a sterilizing sterilizer, it has the advantage of reducing the cost of sterilization, and can further provide a medical instrument sterilizer that is more effective than the conventional sterilization method.

Figure 3 simply shows the disinfection process and packaging process of the medical device according to an embodiment of the present invention.

Hereinafter, with reference to the accompanying drawings will be described an embodiment of the present invention in more detail. However, the present invention is not limited to the embodiments disclosed below, but will be implemented in various forms, and only the embodiments are intended to complete the disclosure of the present invention, and to those skilled in the art to fully understand the scope of the invention. It is provided to inform you. Like numbers refer to like elements in the figures.

1 is a view showing a medical instrument sterilizer using the OH (hydroxyl group) radicals according to an embodiment of the present invention, Figure 2 is a view showing a medical instrument sterilizer and a vacuum packaging unit using the OH (hydroxyl group) radicals viewed from the front.

OH (hydroxyl group) radical medical instrument sterilizer according to an embodiment of the present invention, by disinfecting and drying the medical instrument used by injecting OH (hydroxyl group) radicals into water, as shown in Figure 1, water The storage tank 110 and the OH (hydroxyl radical) generating unit 120 are stored are connected around the sterile disinfection unit 130.

First, the storage tank 110 is a device for storing the stored water, the water stored in the storage tank 110 through the water supply port 112 may be supplied to the sterilization disinfection unit (130).

Next, the OH (hydroxyl radical) generating unit 120 discharges gas therein to generate OH (hydroxyl radical) radicals, and the generated OH (hydroxyl radical) radicals are injected into the sterilization disinfection unit 130 through the inlet 122. May be injected.

Next, the sterilization disinfecting unit 130 may mix the water supplied with the injected OH (hydroxyl) radicals, and receive the mixed solution to disinfect the medical device.

Next, the drain 132 is disposed on the lower surface of the sterilization sterilization unit 130, it is used to discharge the mixed liquid used to disinfect the medical device.

Next, the cover 134 is included in the sterile disinfecting unit 130, through the opening and closing of the cover 134 can easily put the medical device into the sterile disinfecting unit 130, take out, and also, the cover 134 When closed, the sterilization disinfection unit 130 can be sealed to increase the disinfection efficiency.

Then, the drying unit 140 has a structure attached to the lower end of the cover 134, and is used to dry the sterilized medical apparatus after the mixed liquid used for disinfection is discharged through the drain 132.

As shown in FIG. 2, in the present embodiment, the water inlet 112 may be disposed on one surface of the storage tank 110 and may be disposed above the center line in the vertical direction of the sterilization disinfecting unit 130.
