The frame has a front wall (10a), side walls (10b), and side arms (12), and a support platform (11) extending rearwardly from the front wall (10a). An inlet opening (13) is defined in the support platform (11). The body (2) forms a chamber with the support platform (11) and comprises at least one nasal outlet (5), a base opening (7), and at least one further opening (6), through which the support platform (11) extends. The inlet conduit (4) comprises a connector (18) that clamps the body (2) and the support platform (11) together.

A patient interface comprises a seal-forming structure including a textile membrane and a support structure to support the textile membrane. The seal-forming structure may have a varying construction in order to accommodate different regions and the varying contours of the patient's face to ensure a robust and comfortable seal. An air impermeable layer of the textile membrane may have a thickness that varies in different portions of the textile membrane and/or different regions of the cushion assembly. Further, the seal-forming structure may include an underlying cushion, and an arrangement of the textile membrane and the underlying cushion and/or the configuration of the underlying cushion may vary in different regions of the cushion assembly to optimize patient comfort and the effectiveness of the seal in different regions of the patient's face.

Disclosed are apparatus and methods of detecting user interaction with a respiratory therapy device and effecting an action in response to the detection. The apparatus comprises a sensor which is positioned so as to detect the presence of a user's hand or fingers near to the apparatus, such as a surface or handle. In embodiments the apparatus may be configured to detect gestures or movement of the user. On detection of a user, the apparatus may be configured to effect one or more actions, such as disabling a feature of an input or output device or alerting a user.

A mask system and an air delivery conduit for use in the treatment of respiratory disorders. The air delivery conduit may comprise a textile having an airtight arrangement. A support structure may be provided to the conduit to provide form.

The present invention relates to a method for controlling a thermoregulated ventilation circuit (100) equipped with a control unit (40) and comprising an active humidifier (10). The active humidifier (10) further comprises, in turn, a cartridge (20) equipped with a humidification chamber (21) adapted to contain water to be heated for the humidification of the air through a heating element (30), and the thermoregulated circuit (100) further comprising at least one intake tube (120) for conveying the air exiting said cartridge and provided with heating means (123) for heating the air exiting said cartridge (20). The method according to the present invention is characterised in that said control unit (40) receives in input the patient's temperature data (Tp) detected by a patient's temperature probe (132) and regulates the operation of said heating element (30) of said cartridge (20) and the operation of said heating means (123) of the air exiting said cartridge (20) as a function of said patient's temperature (Tp).

A clamp (1) releases or blocks a fluid connection as desired. A clamping tube (3, 4, 5.1, 5.2, 7.1) of the clamp (1) includes a blocking fluid guide element (7.1) and two connecting fluid guide elements (3, 4). The blocking fluid guide element (7.1) is connected in a fluid-tight manner to the two connecting fluid guide elements (3, 4). A clamping unit of the clamp (1) includes two clamping components (8.1, 10.1, 8.2, 10.2). The blocking fluid guide element (7.1) is located between the two clamping components (8.1, 10.1, 8.2, 10.2). In a releasing state of the clamping unit, the blocking fluid guide element (7.1) establishes a fluid connection between the two connecting fluid guide elements (3, 4). In a blocking state, the two clamping components (8.1, 10.1, 8.2, 10.2) prevent a flow of fluid through the blocking fluid guide element (7.1).

A patient interface includes a plenum chamber, a seal-forming structure, and a positioning and stabilising structure to provide a force to hold the seal-forming structure in a therapeutically effective position on a patient's head. The positioning and stabilizing structure includes a superior strap portion, an inferior strap portion, and a posterior connecting strap portion connected to or formed integrally with the superior strap portion and the inferior strap portion. The posterior connecting strap portion is constructed from a mesh material that is different than the material used to construct the superior strap portion and the inferior strap portion. The posterior connecting strap portion has a greater stretch capability than the superior strap portion and a lesser stretch capability than the inferior strap portion. The stretch capabilities allow the positioning and stabilizing structure to be removable from the patient's head when the loop engages the connection portion.

The invention relates to providing novel functions to the coaxial breathing circuits which at present do not comprise water traps, by adding a closed system water trap designed to have an inkwell shape and a lung pressure measurement port to said circuits wherein the fluid collected in the bottle section can be discharged without having to open the bottle by means of a drainage luer port located at the base of the bottle and a needleless apparatus that has been inserted into the port, and an injector.

A stator assembly has coils in a distributed winding configuration. A poly-phase switched reluctance motor assembly may include a stator assembly with multiple coils in a distributed winding configuration. The stator assembly may have a central bore into which a rotor assembly having multiple poles is received and configured to rotate. A method of controlling a switched reluctance motor may include at least three phases wherein during each conduction period a first phase is energized with negative direction current, a second phase is energized with positive current and there is at least one non-energized phase. During each commutation period either the first phase or second phase switches off to a non-energized state and one of the non-energized phases switches on to an energized state with the same direction current as the first or second phase that was switched off. The switched reluctance motor may include a distributed winding configuration.

A safety breathing apparatus has a sensor for measuring the difference in pressure between two point 1a, 1b in the gas delivered to a head unit 9. The sensor is used to measure the difference in the pressure of the gas supplied through the apparatus between the two points in the gas flow, and the pressure difference is then used to calculate the gas flow rate.
