Main preventive methods against the anesthetic gas pollution in the operating rooms consist of the attachment of the anesthetic gas scavenging systems for all anesthetic machines and the introduction of the all fresh air system for air ventilation of the operating rooms. Ether one is not enough for the effective antipollution. By the way, the all fresh air system is usually very expensive for the installation of its equipment and in the running cost. So, most of small scale hospitals in Japan are apt to use the recirculating systems instead of this system.In this investigation, we are trying to create a new continuous air-cleaning apparatus for the pollutants of anesthetic and/or bactericidal gases or vapors in the recirculating air inside the duct. In this apparatus, the endless belt of the activated carbon moves slowly into the duct, then moves as the reverse M shape inside the duct, and goes out again from the duct. Inside the duct, the activated carbon is able to adsorb the pollutants from the recirculating air. Afterwards, when the belt comes out of the duct, the activated carbon receives hot air shower for the purpose of the desorption of the pollutants. After the belt of the activated carbon is cooled down by cold air blow in order to recover the adsorbability, it enters again into the duct. So, this apparatus can work like a pump which is drawing out the pollutants from the recirculating air inside the duct. We decided Kuractive^<<ﾟ!>> FT-300-20 is the best activated carbon for our purpose. After the repeated improvements, the trial apparatus has been completed. In the flow of the sham anesthetic-gas-polluted air of the duct, the belt speed of 150 cm/min. was the best. In the future, we are planning to use the endless belt of FT-300-20 covered with FT-300-10, which will increase the adsorbability of nitrous oxide. Furthermore, the bactericidal gases and vapors might be tried for this apparatus, like the anesthetic gases and vapors.

预防手术室麻醉气体污染的主要措施是在所有麻醉机上加装麻醉气体净化系统和引入全新风系统对手术室进行通风。乙醚是不够的，有效的抗污染。顺便说一句，全新鲜空气系统的设备安装和运行成本通常非常昂贵。因此，日本的小型医院大多倾向于使用循环系统来代替该系统。在本研究中，我们试图创造一种新的连续空气净化装置，用于处理管道内循环空气中的麻醉和/或杀菌气体或蒸汽污染物。在该装置中，活性炭的环形带缓慢地移动到管道中，然后在管道内以反M形状移动，并再次从管道中出来。在管道内，活性炭能够从再循环空气中吸附污染物。之后，当带从管道出来时，活性炭接受热空气淋浴，以解吸污染物。在活性炭带通过冷空气吹冷却以恢复吸附性之后，其再次进入管道。所以，这个装置可以像一个泵一样工作，从管道内的循环空气中抽出污染物。我们决定Kuractive^<<！>> FT-300-20是最适合我们用途的活性炭。经过反复改进，试制装置已经完成。在模拟麻醉气体污染的气道气流中，以150 cm/min的带速为最佳。今后，我们计划使用FT-300-20的环形带覆盖FT-300-10，这将增加一氧化二氮的吸附能力。此外，杀菌气体和蒸汽可用于该装置，如麻醉气体和蒸汽。
