Development and clinical utility of membrane humidifier without need of water for humidification

这是众所周知的，因为传统泡沫中的人类有能力生产与细菌相关的微气溶胶。我们开发了一种独特的人性化元件，称为膜人性化元件，它不需要外部水供应。这个新系统可以从房间空气中移动。我们调查了膜湿度的临床和体外评估，并参与了研究中的十个病人与慢性脉搏病有关。We evaluated the partial pressure of oxygen in arterial blood （PaOイイD22エD2） of 10 patients who used the new device。我们在体外进行了一项研究，以确定该设备可以防止人类氧化物通过内部的空心纤维被采样到10天内的营养生长周期。我们也比较了Oxygen humidified by a membrane humidified with that of oxygen humidified by a bubbling humidifier.There was no significant between measured PaO y D22 while breathing oxygen humidified using a membrane humidified and while breathing oxygen humidified using a bubbling humidifier.人类氧化物的文化通过了空洞纤维对细菌产生了负面影响。膜类风湿性器官可以产生良好的人性化：一种新的设备出现在防止细菌感染的情况下，并可能有助于减少医院和家庭患者感染的风险。

It is well known that conventional bubbling humidifiers are capable of producing micro-aerosols contaminated with bacteria. We developed a unique humidifier named as membrane humidifier that does not require an external water supply. This new system obtains moisture from room air. We investigated the clinical and in vitro evaluation of membrane humidifier.Ten patients with chronic pulmonary disease participated in the study. We evaluated the partial pressure of oxygen in arterial blood (PaOィイD22ィエD2) of 10 patients who used the new device. We conducted an in vitro study to determine whether the device could prevent the bacterial contamination of humidified-oxygen passed inside the hollow fibers was sampled into nutrient broth periodically for 10 days. We also compared the relative humidity of oxygen humidified by a membrane humidifier with that of oxygen humidified by a bubbling humidifier.There was no significant difference between measured PaOィイD22ィエD2 while breathing oxygen humidified using a membrane humidifier and that while breathing oxygen humidified using a bubbling humidifier. Cultures of the humidified-oxygen passed through the hollow fibers were negative for bacteria. The membrane humidifier could produce well humidification.The new device appeared to prevent bacterial contamination, and may help to reduce the risk of infection in patients at hospital and home.
