加湿チャンバーを使用せず,メッシュ状の疎水性中空糸に水を通し,熱線で加熱する機構をもった新開発加温加湿器(HUMMAX<sup>®</sup>)の性能試験を目的とした.方法:10, 20, 30l•min-1の空気定常流をHUMMAX<sup>®</sup>に流し,設定温度35, 37, 39°C,熱線出力電圧20, 26, 30Vで吸気回路出口の温度,相対湿度,絶対湿度を測定した.結果:すべての設定で85%以上の相対湿度と32mg•l-1以上の絶対湿度を記録したが,出力20Vと30Vでの温度制御に問題があり,相対湿度の若干の低下が認められた.結語:HUMMAX<sup>®</sup>は出力26Vで相対湿度(範囲91~99%),絶対湿度(範囲35~44mg•l-1)ともに十分な性能が認められた.

The purpose of this study was to test the newly developed humidifier HUMMAX<sup>®</sup>, by Metran Corporation Japan, that has mesh-like holofibers covering a heating wire without a water chamber. Water is supplied through the holofibers. Methods: Temperature, absolute humidity (AH), and relative humidity (RH) were measured at the exit of the inspiratory limb of HUMMAX<sup>®</sup> under a unidirectional constant flow (10, 20, 30l•min-1). The temperature settings were 35, 37, and 39°C and the heating wire outputs were 20, 26, and 30V. Results: Although gases were above 85% RH and 32mg• l-1 AH in all settings, RHs were slightly lowered at a heating wire output of 30V. Discussion: As water is supplied into the holofiber and vaporized according to the temperature set by the heating wire, the high RH is consequently assured at any temperature. The AHs observed here almost satisfied the ISO's minimum criterion of 33mg•l-1. Conclusion HUMMAX<sup>®</sup> had sufficient performance capability in supplying high RH (91-99%) and AH (35-44mg•l-1) at 26V of heating wire electrical output.
