With the increasing requirements for use at any time, the end of modern hospital operating rooms are equipped with high-efficiency filters to achieve the purpose of purification, but there are often users who run in the operating room for a period of time will have the problem of excessive bacteria, and point to the source of the problem High-efficiency filter, now explain to friends the main function of a high-efficiency air filter, let friends understand that in fact, high-efficiency filters are not omnipotent;
High efficiency air filter filtration principle:
The dust particles in the air move inertially with the airflow, or move randomly, or move by a certain field force. When moving dust particles hit the filter, the gravitational force between the particles and the surface of the high-efficiency filter makes it stick to the filter.
The filtration efficiency of the high-efficiency filter for the 0.3um dust in the air can reach more than 99.99%, so the above principle, the high-efficiency filter only has the function of filtering dust; it neither produces microorganisms, nor does it have the function of filtering microorganisms.
When replacing the high-efficiency air filter, it is best to let the experimenter who uses it be present (ask the bacteria used in the experiment in advance). Persons with trauma to their hands and bodies are not allowed to operate. Operators must wear gas masks and rubber gloves. The taken-out filter should be sealed immediately and put into the take advantage of the bag, and then put into the carton. The used mask and gloves should be treated in the same way, and then burned together. When installing a new filter, do not stretch your head and body into the device casually, and also operate with a high degree of caution. In addition to using a high-efficiency filter to remove bacteria in the exhaust air, an incinerator can also be used to achieve this purpose. It is absolutely unreliable to sterilize the exhaust air with a UV lamp.
However, if the operating room is used for a period of time, the bacteria exceeding the standard may be half of the problem due to the high-efficiency filter, or other management problems, such as the timing cleaning is not up to the standard, then just replace the high-efficiency filter. Can find the source of the problem.
