Introduction of Acidic Oxidation Potential Water
Acidic oxidizing potential water is made by adding low concentration of sodium chloride to softened water and then adding an ion membrane electrolyzer. After electrolysis, an acidic aqueous solution with high redox potential and low concentration of available chlorine is generated from the anode side, and a sodium hydroxide solution is generated at the cathode side.
Acidic oxidizing potential water, as a new type of green disinfectant, was developed in Japan in the 1980s and introduced to my country in the mid-1990s. In recent years, it has been widely used in the fields of medical care, military, food, animal husbandry, aquaculture, agriculture, etc.
Killing of microorganisms by acidic oxidative potential water and its influencing factors
Acidic oxidative potential water can destroy the bacterial membrane system, change the permeability of the cell membrane, destroy the superstructure of bacteria, and thus kill bacteria. Experiments have shown that acidic oxidative potential water kills microorganisms quickly and efficiently, with an antibacterial spectrum. It can completely kill Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, Acinetobacter baumannii, Bacillus subtilis black variant spores, etc. in just 10 seconds. It is a disinfectant with a high level of disinfection ability. Studies have shown that the inactivation rate of artificially contaminated hepatitis B virus surface antigen instruments is as high as 100% when they are soaked in acidic oxidative potential water for 10 minutes.
Application of Acidic Oxidative Potential Water in Medical Field
01 Disinfection of hemodialysis equipment
Some scholars have used acidic oxidative potential water for disinfection and cleaning of the hemodialysis machine's piping system, that is, for soaking the parts of the dialysis machine. As a result, no corrosion was found in the parts. The disinfected dialysis machine piping system met the requirements and the disinfection effect was good. The experimental group also used acidic oxidative potential water to wipe the inner surface and surface of the dialysis machine's quick interface and the connector surface of the quick interface on the dialysis machine. As a result, the number of colonies was significantly reduced.
02 Disinfection of wound surface, skin and mucous membrane
Acidic oxidative potential water is non-irritating to the skin and mucous membranes, and has a slight anesthetic effect on the wound surface. Adequate acidic oxidative potential water is used to rinse the burn wound surface, which has a good effect and can effectively prevent infection without adverse reactions. At the same time, acidic oxidative potential water can be used for oral care, which can effectively control and reduce the bacterial infection rate of the patient's oropharynx, reduce bad breath, oral ulcers, and prevent respiratory infections.
03 Application in dentistry
According to the irrigation treatment, acidic oxidative potential water is used for root canal irrigation combined with ultrasonic treatment and preparation for obstructive root canalitis treatment, disinfection of pulpitis and apical periodontitis, and the effect is good. It is considered to be a safe, efficient and useful method. Studies have shown that acidic oxidative potential water can effectively kill bacteria in the root canal and remove the root canal smear layer. Studies have shown that acidic oxidative potential water is a new type of root canal irrigation fluid that can be used for oral root canal irrigation. At the same time, acidic oxidative potential water can also be used for oral care. There are many colonizing bacteria in the normal oral cavity. The bacteria in the oropharynx are highly homologous to the pathogenic bacteria of respiratory tract infections. The use of acidic oxidative potential water for oral care can reduce the colonization rate of oral pathogens in patients with mechanical gas without adverse reactions. At the same time, acidic oxidative potential water was used for oral cleaning of patients with orotracheal intubation. The results showed that the oral bacteria removal rate was 95.21%, the incidence of halitosis was 3.31%, the oral fungal infection rate was 0, and the incidence of oral ulcers was 10%. It is believed that acidic oxidative potential water as oral care can effectively reduce or control the number of bacterial colonization in the oropharynx of patients with orotracheal intubation. It can effectively reduce the incidence of bad breath and prevent respiratory infections. Studies have also found that the use of acidic oxidative potential water for oral care can reduce the number of colonies in the oral mucosa and control and prevent oral complications.
At the same time, acidic oxidative potential water can also be used for oral impressions. The disinfection of oral impressions on comprehensive treatment tables is contaminated by blood or saliva, which is prone to cross-infection during the process of remaking plaster models. Experts compared the disinfection effects of other chlorine-containing disinfectants and acidic oxidative potential water on oral impression materials and the effects of other disinfectants on models. The results showed that the impressions treated with acidic oxidative potential water atomization did not deform and did not affect the accuracy and quality of the restoration. This disinfection method is an effective method for treating oral impressions.
The contamination of dental treatment table water system has always been a clinical problem. Acidic oxidation potential water was used as a disinfectant for dental treatment tables. The results showed that the bacterial content in the dental treatment table water system after disinfection with acidic oxidation potential water was 0, and no microorganisms were generated. It is believed that this method can thoroughly and effectively disinfect the dental treatment table water system.
Summarize
Hypochlorous acid/HOCL water/Acidic oxidizing potential water is a new type of environmentally friendly, green disinfectant that has replaced traditional chemical disinfectants in many clinical fields. It has the advantages of easy preparation, fast degradation, no pollution, low cost, simple use and good effect.
