Plasma activation hydrogen peroxide solution preparation device and preparation method

Abstract

The invention provides a plasma activation hydrogen peroxide solution preparation device and preparation method. Hydrogen peroxide solution can be used for medical disinfection, wound disposal and oral disease prevention and treatment. The device comprises a control module, a water storage bin, a 30% hydrogen peroxide storage bin, a plasma module, an activation bin, a neutralization bin and a water containing module. The preparation method includes the steps: selecting the concentration, the volume and the pH (potential of hydrogen) value of the hydrogen peroxide solution and the quantity of active particles in the solution on a control panel; preparing the hydrogen peroxide solution with a specific concentration in an activation cavity and mixing the hydrogen peroxide solution with plasma generated by the plasma module; stabilizing the pH value of the solution in the activation cavity at a pH value set by a user to obtain needed activation solution.

Description

technical field [0001] The invention relates to the field of medical sterilization, in particular to a preparation device and method for plasma-activated hydrogen peroxide solution. Background technique [0002] Low-temperature sterilization technology is often used in the sterilization of medical devices. There are three commonly used methods: ethylene oxide low-temperature sterilization, 2% glutaraldehyde immersion sterilization, and hydrogen peroxide plasma low-temperature sterilization. However, the ethylene oxide low-temperature sterilization method and the 2% glutaraldehyde soaking sterilization method have disadvantages such as potential toxicity, corrosion to medical devices, and long sterilization time in use. Hydrogen peroxide plasma low-temperature sterilization is expensive, and the sterilization device is expensive. [0003] 70% alcohol is often used for skin disinfection, but it is irritating when used for mucous membrane and wound disinfection. When the high...

AI Technical Summary

Problems solved by technology

However, the ethylene oxide low-temperature sterilization method and the 2% glutaraldehyde soaking sterilization method have disadvantages such as potential toxicity, corrosion to medical devices, and long sterilization time in use.

Hydrogen peroxide plasma low-temperature sterilization method is costly, and the sterilization device is expensive

[0003] 70% alcohol is often used for skin disinfection, but it is irritating when used for mucous membrane and wound disinfection

Studies have shown that 0.5% povidone-iodine gargle has the strongest oral sterilization effect among these gargles, followed by two chlorhexidine gargles, 0.1% cetylpyridinium chloride gargle, 3% Hydrogen peroxide gargle has the weakest bactericidal effect

The 3% hydrogen peroxide gargle has a weak bactericidal effect, relies on the generation of oxygen bubbles in the mouth to perform mechanical cleaning, and is accompanied by unacceptable foam odor

However, when there is blood or pus in the lesion in the oral cavity, its antibacterial activity decreases

In addition, long-term use of povidone-iodine gargle may lead to excessive iodine levels in the body
