A diagnostic tool and methods of using the tool are provided to quantify an amount of nasal collapse in a patient. The diagnostic tool includes a mask with an endoscope port and an opening to allow air flow, an endoscope with a camera adapted to take an image of the nasal valve, and an air flow sensor adapted to measure an inhalation rate of the patient. The diagnostic tool can quantify a size difference between the nasal valve during inhalation and zero flow by calculating a percentage difference in an area or one or more dimensions of the nasal valve during inhalation and zero flow.

A headgear assembly includes a first arm member and a second arm member each having a first end and a second, opposing end. The first end of the first arm member has a structure sized and configured to engage a first rotation-resistant coupling of a frame in a manner which prohibits rotation of the first arm member with respect to the frame in a first plane in which the first arm member is located. The first end of the second arm member has a structure sized and configured to engage a second rotation-resistant coupling of the frame in a manner which prohibits rotation of the second arm member with respect to the frame in a second plane in which the second arm member is located. The assembly further includes a strap member coupled to the first and second arm members.

Examples of a module for housing unrelated electronic and electromechanical equipment for use during surgery. The module can include a lower section and a tower-like upper section. The lower section can house unrelated electronic and electromechanical equipment. The tower-like upper section can be located on top of the lower section. A water-resistant cowling can enclose at least a portion of the lower section and the tower-like upper section. A cartridge containing one or more ultraviolet-C producing lights can be protectively housed within the tower-like upper section. The cartridge containing one or more ultraviolet-C producing lights can be configured to emerge upward from a top of the tower-like upper section to substantially seat itself on the top of the tower-like upper section when activated allowing the ultraviolet-C light to disinfect the patient and staff-contacting upper surfaces of the equipment in the operating room.

Disclosed is a respiratory interface device (1) and components thereof. The respiratory interface device (1) comprises a body (2), a frame (3), and an inlet conduit (4). 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.

An apparatus and methods enhances the energy levels of a person, in particular the relating to guiding a person's breathing to enhance energy and health. The device is a breath guide device having an airway, breathflow guiding equipment, a control unit capable of communicating with a memory unit. The control unit is arranged to control the breathflow guiding equipment in dependence on data held in the memory unit. A mouthpiece suitable for placement at a user's mouth may be included. The breathflow guiding equipment includes an electronically operated valve for regulating the flow of breath through the airway.

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.

A patient interface system for delivering breathable gas to a patient includes a patient interface configured to sealingly engage the patient's face. A mechanism may be provided to ensure that an effective seal is maintained between the patient interface and the patient's face by preventing, reducing, minimizing or limiting effects of disruptive forces, such as tube drag, on the patient interface.
