    Abstract: A patient interface is described which is reduces the pressure of the mask on the users face. The patient interface has a sealing interface having an inner sealing member and an outer sealing member. The inner and outer sealing members are adapted to seal around the facial contours of a user providing a sealed fluid communication to the user's respiratory tract. The inner and outer sealing members are at least continuously in contact with each other around the portions where the sealing interface contacts the user's facial contours. The inner sealing member may be provided with cut outs to provide additional flexibility to particular areas, such as the nasal bridge, upper lip or cheek regions and may be provided with a contoured edge to better fit the facial contours of a user.

    Abstract: A flow probe for use in a humidification system is positioned in a humidified gases flow such as that which is provided to a patient in a hospital environment. The flow probe is designed to provide both temperature and flow rate sensing of the gases flow by incorporating two sensors into the gases flow. The flow probes are shaved and aligned within the gases flow to enable accurate gas flow readings to be taken whilst reducing the occurrence of condensation on the sensors. The flow probe can also be included in a humidification control systems to provide a patient with a desired humidity level or simplify the amount of user input required to set humidity levels. Furthermore, the flow probe can provide a controller with flow information which may then be used to determine certain conditions that could prove to be dangerous to a patient.

    Abstract translation: 用于加湿系统的流量探针定位在加湿气体流中，例如在医院环境中提供给患者的气体流。 流量探头设计用于通过将两个传感器并入到气体流中来提供气体流量的温度和流量检测。 流动探针在气流中被剃刮并对准，以使得能够精确地获得气体流量读数，同时减少传感器上的冷凝发生。 流量探头也可以被包括在加湿控制系统中，以向患者提供所需的湿度水平或简化设定湿度水平所需的用户输入量。 此外，流量探针可以向控制器提供流量信息，然后可以使用流量信息来确定可能被证明对患者危险的某些状况。

    Abstract: A medical breathing assistance apparatus (20) for supplying pressurised gases to a patient is disclosed. The breathing assistance apparatus (20) comprises a heating chamber (29) and a pressure chamber (27) both adapted to contain water, and at least one pressure adjusting means (24,25,26). The pressure chamber (27) is connected to the heating chamber (29) and the pressure adjusting means (24,25,26) is located between the heating chamber (29) and a gases supplying means (23) supplying gas to both the pressure chamber (27) and heating chamber (29). The pressure adjusting means (24,25,26) is adapted to convert pressurised gases from the gases supply means (23) to two different pressures, one to each of the heating chamber (29) and the pressure chamber (27), so that water flows from said pressure chamber (27) to the heating chamber (29).
