Management requirements of purification engineering in operating room
1、 The building layout, basic equipment, purification air conditioning system and room classification of operating room purification shall conform to the standard of building technical code for clean operating Department of hospital gb50333-2013.
2、 After entering the clean area of the operating room, the personnel in the clean area shall replace the special clean clothes.
3、 In order to purify the buffer zone of each area in the operating room, obvious signs and barriers shall be set up. The doors of each area shall be kept closed at all times, and there shall be interlocking devices, which shall not be opened at the same time.
4、 The operating room purification temperature should be controlled at 22 ℃ ~ 25 ℃, the relative humidity is 40% ~ 60%, the noise is 40 ~ 50dB, and the average illumination of the operating room lighting is about 500lx.
5、 The clean air conditioning system of the operating room shall be opened 30 minutes before the operation; the clean air conditioning system of the clean operating department shall operate continuously until the cleaning and disinfection work is completed. The operation time of class I-II rooms is 20 minutes after the completion of cleaning and disinfection, and that of class III-IV rooms is 30 minutes after the completion of cleaning and disinfection.
6、 The air supply outlets such as non leak proof orifice, grille and wire mesh in the clean area shall be cleaned every week, and any pollution shall be cleaned at any time.
7、 Vertical bars shall be used for the air return grille in the clean area, which shall be wiped and cleaned once a day and thoroughly cleaned every week. If there is pollution, it shall be cleaned at any time, and the filter material layer shall be replaced according to the requirements of Table 3.
8、 After each operation, the negative pressure operating room should be operated continuously for 15 minutes before cleaning and wiping, and the next operation can be carried out only when the self-cleaning requirements are met. The exhaust air filter for filtering pathogenic aerosols shall be replaced every six months.
9、 The drainage point of condensate shall be inspected every day and cleaned every week.
In the hospital, purification engineering is widely used in the operating room, but also in the delivery room, central baby room, burn area, ICU, hemodialysis room, central supply room, pharmaceutical factory and other areas, and has achieved very excellent results. In the future, purification engineering will be applied in more areas where there is a need, and will also produce more benefits to people's lives.
The professional technicians of EDE purification engineering design the scheme that is suitable for the production process and reasonable project cost. The design technical indicators meet the national standard of clean room. The experienced purification engineering construction team is fast and efficient, and the after-sales service is perfect.
