A hospital is a place with particularly high requirements for air quality. Whether it is an operating room, a ward, or a baby room or a delivery room, a certain level of cleanliness must be maintained, because the cleanliness of the hospital may be related to thousands of patients. Therefore, in addition to daily cleaning and disinfection, hospital air purification is also particularly important.

The emergence of operating room filters not only meets the requirements of air temperature, humidity and cleanliness during the operation, but also creates a comfortable environment for medical staff to work, and is also of great benefit to the recovery of patients. The importance of operating room filters to hospitals is beyond reproach, so do you know what are the selection principles of operating room filters?


Selection Principle of Operating Room Filter

The selection requirements of operating room filters are relatively high, involving the selection of inlet and outlet diameters, filter materials, and the number of holes.

Generally speaking, the inlet and outlet diameter of the filter should not be smaller than the inlet pipe diameter of the matching pump. The material of the filter is generally the same as that of the connected process pipeline. For different service conditions, the filter of cast iron, carbon steel, low alloy steel or stainless steel can be considered.

At the same time, in order to strictly control the air quality and intercept all kinds of impurities, there are also strict requirements in the selection of the number of pores of the filter in the operating room. In addition, we also need to calculate the filter resistance loss of the operating room filter, and at the same time determine the pressure level of the filter according to the highest possible pressure in the filter pipeline, and the nominal pressure is the best.


How to maintain the operating room filter?

Operating room filters are relatively common purification equipment, and many people only pay attention to their use, but ignore the maintenance work. In the process of using the operating room filter, we also need to do the installation and maintenance of the operating room filter.

Did you know that when the filter has been working for a period of time, the filter element of the operating room filter may precipitate a certain amount of impurities. If it is not cleaned and maintained in time, it may cause the pressure to increase and the flow rate to drop, which greatly affects the operation. The overall purification effect of the room.

As a staff of the operating room filter, it is necessary to clean up the impurities in the filter core in time to ensure the normal use of the filter. If the wire mesh is found to be deformed or damaged, it needs to be replaced immediately.
