PROBLEM TO BE SOLVED: To provide an operating room air conditioning system that can prevent dew condensation of a lens of a laparoscope in a laparoscopic operation.SOLUTION: An operating room air conditioning system 10 performs air conditioning of an operating room 1. The operating room air conditioning system 10 includes a first air diffuser 21 provided direct above an operating table 5 and a second air diffuser 31 provided around the first air diffuser 21. Air having a temperature higher than the room temperature is diffused toward an operating table 5 from the first air diffuser 21 and air having a temperature lower than the room temperature is diffused from the second air diffuser 31 toward the surrounding of the operation table 5.COPYRIGHT: (C)2013,JPO&INPIT【課題】腹腔鏡手術の際に、腹腔鏡のレンズの結露を防止できる手術室空調システムを提供すること。【解決手段】手術室空調システム10は、手術室1を空調する。この手術室空調システム10は、手術台5の直上に設けられた第1吹出口21と、この第1吹出口21の周囲に設けられた第2吹出口31と、を備える。第1吹出口21は、室温よりも高温の空気を、手術台5に向かって吹き出し、第2吹出口31は、室温よりも低温の空気を、手術台5の周囲に向かって吹き出す。【選択図】図1
