ABSTRACT

Objective Mobile operating compartment with overpressure protection can provide a safety environment for the patients and the surgical team by minimizing the risk of biochemical contamination through appropriate air filtration, steady overpressure foundation and air distribution scheme. Methods The air movement and the temperature distribution inside the mobile operating compartment with the overpressure protection performance were simulated by the technique of computational fluid dynamics(CFD), the air pattern and the temperature distribution were analyzed. Results The air velocity was under 0.5m/s in the most zone of person activity and the air velocity were distributed uniformly in the mobile operating compartment under the condition of the overpressure protection system. The obvious temperature gradient didn't exist in the vertical plane of the mobile operating compartment. The temperature distribution in the mobile operating compartment was quite uniform and the temperature was almost at 27℃ with the temperature difference of almost 2℃. Conclusion The human thermal comfort is good in the mobile operating compartment and the environment in the mobile operating compartment can satisfy requirements of the operation.
