Client Background
A regional heart centre wanted to combine a Class I (ISO 5) operating room with a state‑of‑the‑art angiography suite. The new hybrid cath lab would support both open‑heart surgery and minimally invasive endovascular procedures.
Needs & Challenges
· ISO 5 cleanliness (U.S. Class 100) for open chest cases.
· Radiation shielding: 2mmPb equivalent for walls and ceiling due to high‑power fluoroscopy.
· Equipment compatibility: Large ceiling‑mounted DSA (digital subtraction angiography) must move freely without interfering with the laminar airflow diffuser.
· Clean / dirty separation: Easy‑to‑clean surfaces with seamless flooring for rapid decontamination between case types.
· Tight floor space: Only 55 m² available for both surgical and interventional setups.
Solution
· Custom airflow design: Offset laminar flow diffuser (2.8 m × 2.4 m) positioned to clear the DSA parking zone – validated with smoke studies.
· Lead‑lined modular panels: Electro‑galvanized steel panels with factory‑applied 2mmPb lead backing. Fully welded joints for both sterility and radiation safety.
· Integrated control system: Single touch panel that switches between “surgical mode” (high air changes) and “interventional mode” (reduced turbulence for imaging) while maintaining positive pressure.
· Rapid turnover protocol: Designed flush‑mount medical gas outlets and recessed lighting to eliminate dust traps.
Summary
Yaning's one-stop operating room solution is designed to provide a high degree of flexibility and adaptability for practical clinical applications.
