[0002] The static pressure box is a necessary accessory in the air supply system to reduce dynamic pressure, increase static pressure, stabilize airflow and reduce airflow vibration. The function of the static pressure box is to convert part of the dynamic pressure into static pressure, so that the wind can blow farther, reduce noise, ensure uniform distribution of air volume, obtain uniform static pressure air output, and reduce dynamic pressure loss. Nowadays, static pressure boxes are widely installed in hospital operating rooms. Static pressure boxes are usually connected to ventilation ducts to help air circulation in the operating room while maintaining excellent air quality in the operating room.

At this time, the fixed static pressure box 1 cannot be guaranteed to fall exactly above the operating bed, and the static pressure wind blown out is offset from the operating bed, so that the air purification in the operating area does not meet the design requirements.
