摘要： A single ended or double-ended blower includes a blower motor assembly supporting opposed first and second shaft ends. The first and second shaft ends have respective first and second impellers attached thereto and enclosed within first and second volutes, respectively. The first volute is connected to an inlet and the second volute is connected to an outlet. The blower motor assembly is supported in a chassis enclosure. A radially outer inter-stage path is between the first and second volute. The second volute is at least partially substantially concentrically nested with the radially outer inter-stage gas path.

摘要： A CPAP or other ventilation system includes a mask, a flow generator, a positive or high pressure line to provide positive or high pressure air from the flow generator to the mask and a vacuum or return line provided to actively extract exhaled gas from the breathing chamber and/or the air delivery conduit of the mask. The vacuum or return line includes a vent outlet preferably positioned remote from the mask.
摘要翻译： CPAP或其它通风系统包括掩模，流量发生器，正压或高压管线，以从流量发生器到面罩提供正压或高压空气，以及真空或回流管线，用于主动地从呼吸室抽出呼出气体 和/或掩模的空气输送管道。 真空或返回管线包括优选地远离掩模定位的通气口。
