Modular Operating Room (Modular OT) is a pre-engineered, factory-prefabricated integrated sterile surgical space, replacing traditional on-site wet construction. All wall, ceiling, door, cabinet and purification components are standardized modular modules produced in factory, then quickly assembled on-site with aluminum sanitary extrusion profiles, cutting construction period by over 50% and drastically reducing on-site dust and pollution risks.

1. Class100 Positive Standard Modular OT: General surgery, orthopedics, ophthalmology, plastic surgery (ISO5 laminar flow above operating table)
2. Negative Pressure Modular OT: Infectious disease, respiratory pathogen surgery, prevents pathogen outward leakage
3. Radiation Protection Modular OT (Interventional OT): Built-in lead-lined wall & radiation-proof sliding hermetic door for CT/DSA cardiovascular & neuro interventional surgery
4. Digital Intelligent Modular OT: Integrated surgical imaging, remote teaching, whole-room linkage intelligent control
