呼吸气体的加湿
摘要：
一种用于加湿待输送给患者的可呼吸气流的加湿器(14)，包括：腔室(16)，其配置为接收可呼吸气流；箱(20)，其配置为容纳供给水，且箱配置为插入到腔室中；盖(18)，其设置在腔室上并且能够在打开位置和闭合位置之间运动；以及密封件(19)，其设置在盖上，密封件配置为密封腔室从而使得可呼吸气流对腔室加压。加湿器可连接到被配置为产生可呼吸气流的气流发生器(12)上。用来输送经加湿的气流的管可以连接到加湿器上。管可为加热管或非加热管。一种用于将可呼吸气流输送给患者的呼吸装置可包括加湿器和气流发生器和/或管。一种加湿可呼吸气流的方法包括：密封容纳供给水的腔室；以及通过将可呼吸气流引导到腔室中而对腔室加压。
摘要（英）：

A humidifier (14) for humidifying a flow of breathable gas to be delivered to a patient includes a chamber (16) configured to receive the flow of breathable gas; a tub (20) configured to contain a supply of water, the tub being configured to be inserted into the chamber; a lid (18) provided on the chamber and being movable between an open position and a closed position; and a seal (19) provided on the lid, the seal being configured to seal the chamber such that the flow of breathable gas pressurizes the chamber. The humidifier may be connectable to a flow generator (12) configured to generate the flow of breathable gas. A tube for delivering the humidified flow may be connected to the humidifier. The tube may be a heated or non-heated tube. A respiratory apparatus for delivering a flow of breathable gas to a patient may include the humidifier and the flow generator and/or the tube. A method of humidifying a flow of breathable gas comprises sealing a chamber containing a supplying a water and pressurizing the chamber by directing the flow of breathable gas into the chamber.
