Embodiment Construction

[0015] The application of the preferred embodiment of the invention will be better understood with reference to the accompanying drawings.

[0016] figure 1 Schematically shows the composition of the plasma disinfection device equipped with a dehumidifier according to the present invention, figure 2 It is a partial view showing in detail the structure of the dehumidifier which is an important part of the present invention.

[0017] like figure 1 As shown, the sterilization device of the present invention includes a sterilization chamber 10 for accommodating therein a sterilization object 11 such as medical instruments, surgical tools, and the like. Before being introduced into the chamber 10 , the sterilized object 11 is preferably wrapped with a packaging material 12 . A vacuum pump 14 is connected to the lower portion of the sterilization chamber 10 through an exhaust pipe 16 for exhausting air from the sterilization chamber 10 to form a vacuum state.

Abstract

Disclosed is a dehumidifier-equipped plasma sterilization apparatus having a sterilization chamber ( 10 ) for receiving therein a sterilization object ( 11 ); a high frequency power source ( 40 ), connected to a cathode, for generating plasma in optimal condition under control of both an impedance matching controller ( 42 ) and an impedance matching circuit ( 44 ), the cathode being installed, along with an anode at determined distance, in the sterilization chamber, a vacuum pump ( 14 ), connected through an exhaust pipe ( 116 ) to the sterilization chamber, for exhausting air from the sterilization chamber ( 10 ) to form a vacuum state in the sterilization chamber ( 10 ); and a dehumidifier ( 50 ), mounted on the exhaust pipe ( 16 ) for freeze-condensing the water vapor of the gas flowing through the exhaust pipe. In the apparatus, water vapor remaining in the mixed gas used for sterilizing the sterilization object is frozen and removed so that it does not enter the vacuum pump.

Description

technical field [0001] The present invention relates to a plasma sterilizing device which uses plasma to kill any microorganisms present on the surface of objects placed in a sterilizing chamber, such as medical instruments. In particular, the present invention relates to a plasma disinfection device equipped with a dehumidifier, wherein hydrogen peroxide vapor or a mixture of hydrogen peroxide vapor and air is used as a precursor of the bactericidal active substance, water vapor converted from the precursor after disinfection Removed by freezing in a dehumidifier. Background technique [0002] Various devices and methods have been developed for sterilizing single-use or reusable medical instruments or implements. Since environmental pollution has become a prominent problem, environmentally friendly disinfection devices have attracted widespread and in-depth attention. One of the most well-known environmentally friendly disinfection devices is the plasma disinfection devic...
