What purification equipment is needed for the construction of a clean operating room?

  • First, the operating room purification air inlet system needs to install a fresh air filter box, a central purification air conditioner (including three filter sections of primary effect, medium effect and high efficiency), and a high-efficiency air supply outlet at the end. In addition, under certain conditions, a purification booster box needs to be installed.
  • Second, the operating room purification return air system needs to install a return air outlet, a primary filter, and a medium-efficiency return air box.
  • Third, since medical personnel and medical equipment must be thoroughly purified before entering the medical purification clean room, air showers, cargo showers, transfer windows, etc. must also be installed.
  • Fourth, a buffer zone needs to be set up before entering the operating room for purification. The door of the buffer zone needs to be installed with electronic interlocks. Clean storage cabinets, air fresheners, etc. should also be installed in the dressing area.
  • Fifth, some areas within the operating room purification also need to install vertical laminar flow tables, laminar flow hoods (FFU), clean sheds (movable purification work sheds), self-purifiers, etc. that can reach cleanliness levels of 100 to 10,000.
