摘要:
A breathable gas inlet control device permits flow regulation at the inlet of a flow generator for a respiratory treatment apparatus such as a ventilator or continuous positive airway pressure device. The device may implement a variable inlet aperture size based on flow conditions. In one embodiment, an inlet flow seal opens or closes the inlet to a blower in accordance with changes in pressure within a seal activation chamber near the seal. The seal may be formed by a flexible membrane. A controller selectively changes the pressure of the seal activation chamber by controlling a set of one or more flow control valves to selectively stop forward flow, prevent back flow or lock open the seal to permit either back flow or forward flow. The controller may set the flow control valves as a function of detected respiratory conditions based on data from pressure and/or flow sensors.
摘要(中):
可透气的进气控制装置允许在用于诸如呼吸机或连续正气道压力装置的呼吸治疗装置的流量发生器的入口处的流量调节。 该装置可以基于流动条件实现可变入口孔尺寸。 在一个实施例中,入口流动密封件根据密封件附近的密封活化室内的压力变化来打开或关闭送风机的入口。 密封可以由柔性膜形成。 控制器通过控制一组一个或多个流量控制阀来选择性地改变密封活化室的压力,以选择性地阻止向前流动,防止回流或锁定打开密封件,以允许回流或向前流动。 控制器可以基于来自压力和/或流量传感器的数据将流量控制阀设置为检测到的呼吸状况的函数。
