Clean operating rooms represent the most widespread application of cleanroom technology in hospitals; they are modern operating facilities that utilize air purification technology—rather than traditional methods like ultraviolet light—to control contamination throughout the entire process. Hospital cleanroom facilities encompass operating rooms, obstetric units, neonatal intensive care units (NICU), intensive care units (ICU), burn wards, autopsy rooms, purification laboratories, dialysis units, and specimen rooms; the quality of these engineering projects is directly and significantly linked to the quality of medical care. Improving the engineering quality of hospital cleanrooms requires simultaneous attention to design, construction, and maintenance.
Fully grasping the design intent and conducting thorough drawing reviews and technical briefings are crucial technical steps for ensuring construction quality; identifying and resolving technical challenges that are difficult to handle during construction lays a solid foundation for quality assurance. Materials used in cleanrooms must be non-dust-generating, dust-resistant, corrosion-resistant, moisture- and mold-proof, easy to clean, and fire-resistant; wood and gypsum board must not be used as surface finishing materials. HVAC insulation materials must also comply with relevant national regulations, meeting requirements for corrosion resistance, non-dust generation, dust non-adhesion, and fire resistance. Cleanroom construction involves multiple disciplines—including interior finishing, HVAC, electrical systems, and medical gas systems—requiring construction personnel to have a comprehensive understanding of cleanroom construction standards, techniques, and quality requirements.
A key focus of sealing control within the cleanroom is the sealing quality of the enclosure structure; for instance, sealant must be applied evenly between panels to ensure an airtight seal that prevents air leakage. Sealant must also be used to seal the gaps between wall-mounted equipment cabinets and the wall, as well as around sockets, switches, smoke detectors, lighting housings, medical light strips, and X-ray film viewers installed on wall panels; furthermore, reliable and effective sealing measures must be applied to the connections between various pipes and housings within the equipment cabinets. During duct fabrication, emphasis must be placed on cleaning the equipment and implementing sealing measures; high-quality galvanized steel sheets should be used to ensure the ducts are flat, smooth, sturdy, and corrosion-resistant. Sound-absorbing materials used in silencers must be non-dusting, non-shedding, moisture-resistant, and pollution-free; loose-fill materials are prohibited, and fibrous materials must be of the felt type, encased in a covering that prevents fiber penetration. For medical cleanrooms, even small flexible connections must utilize double-layer or insulated flexible connectors; all joints in modular air handling units must be sealed, and a water trap must be installed on the surface cooler's condensate drain pipe to ensure the unit remains airtight and leak-proof.
