It's not a class of medical equipment. First, it depends on whether it is medical equipment. What is the purpose of the ultraviolet lamp car? It's not used to disinfect the environment medical Instrument, give medical Instrument disinfection and ultraviolet ray are medical The device should belong to Class II.
Negative ions do have germicidal effect, but it is required that negative ions reach a certain concentration. A washing machine is equipped with a cheap negative ion generator to ask how much concentration is produced. Are you talking about ultraviolet sterilization? Negative ions and ultraviolet ozone are not the same concept.
UV disinfection is generally only used for air and instrument surface disinfection. Surgical dressings cannot be treated by UV radiation as a routine method.
Ultraviolet radiation is the general term of radiation in electromagnetic spectrum with wavelength from 10nm to 400nm, which can not cause people's vision. In 1801, German physicist Ritter found that the ultraviolet ray could sensitize the photographic negative containing silver bromide at the outer part of the ultraviolet end of the sunlight spectrum, so he found the existence of ultraviolet ray. Too much ultraviolet rays entering the body will cause skin cancer.
It can be disinfected after use every day. It should be disinfected two or three times a week. It is recommended that the toothbrush head should be replaced every three months. It can be disinfected every day. The SEGA toothbrush sterilizer I selected should be disinfected for 6-8 minutes each time. It is a good ultraviolet disinfection lamp. It needs to be equipped with a ballast. Mould formation is due to long-term lack of ventilation and humidity. If ventilation and moisture removal can be achieved, mould will not grow. Since mould has formed, it is necessary to kill it with fungicide first, and then put on a moisture bag such as a charcoal bag. I often do on-site mildew and odor removal projects. You can sprinkle lime on the corner of the wall or place charcoal in the house to absorb moisture when the house is wet. In addition, don't open the window in foggy or rainy weather. Open the window in good weather to ventilate in time.
