Abstract: A patient interface comprises a frame, a headgear, a manifold and two nasal prongs. The frame may be recessed from the face of the patient, and preferably from the manifold so that the manifold may deform or move with respect to the face of the patient. The manifold may be further configured to be compliant in the direction of engagement with the patient's face, such as in the anterior direction. These features may allow the manifold to engage with the face of the patient, such as the upper lip, without exerting a significant pressure which may lead to patient discomfort. The manifold may also be configured to be rotatable with respect to the frame, for example by a grip feature which may be configured to be held in one hand for rotation.

Abstract: The present invention provides for an improved method of determining a water out condition in a humidified gases supply apparatus. The method includes a two step process including a primary determination of a water out condition and a secondary determination of a water out condition. This primary determination is made during observation of the normal operation of the apparatus. During the secondary determination the method takes temporary control over the humidifying part of the apparatus. The secondary determination confirms or contradicts the primary determination.

Abstract: A patient interface comprises a blower, a cushion for contacting a user's face, and a mask body and/or a frame for supporting the cushion on a user's face. The cushion and/or the mask body or frame define an interior space for receiving a flow of gases from the blower. The blower is mounted to the mask body or frame so that the blower is at least partially within the mask body or frame. The blower substantially separates a high pressure side of the mask body or frame from a low pressure side of the mask body or frame and/or the mask body or frame is substantially without a wall between the blower and the interior space.

Abstract: A hydrogen mixed gas generation method using a device that includes a heating pipe housing therein a reduction acceleration member and a heating part including a heating device that heats the heating pipe includes a first process and a second process. The first process includes: causing raw water to flow into the heating pipe and heating the flowing raw water to generate water vapor; heating the generated water vapor to between 500° C. to 800° C.; causing the heated water vapor to be in contact with the reduction acceleration member that is heated along with the raw water to reduce the water vapor and generate hydrogen gas. The second process includes: diluting the hydrogen gas generated in the first process to obtain hydrogen mixed gas whose concentration of hydrogen gas is between 500 ppm to 20000 ppm.
