  • SYSTEM, APPARATUS AND METHODS FOR SUPPLYING GASES
    Publication number: 20180036499
    Abstract: A system, apparatus and methods are provided for supplying gases to a user. The supply includes a sub-therapeutic mode and a pressure support mode for delivering therapy to a user. A flow diversion device or valve switches from a first mode corresponding with the sub-therapeutic mode of the system to a second mode corresponding with the pressure support mode of the system. In the first mode, the valve opens a larger flow path between the interior of the user interface and ambient air than in the second mode.

  • VALVE WITH INTERNAL MEMBER
    Publication number: 20160220781
    Abstract: A valve with an internal member is disclosed which allows exhaled carbon dioxide to escape from a breathing circuit when the circuit gas pressure drops below a threshold pressure. The valve operates by occluding one or more ports under a relatively high pressure and opening the one or more ports under a relatively low pressure. The internal member is attached to the body of the valve at two or more locations on the internal member. The internal member moves in a direction perpendicular to the gas flow through the valve.

  • PATIENT INTERFACES WITH CONDENSATION REDUCING OR COMPENSATING ARRANGEMENTS
    Publication number: 20160008566
    Abstract: Mask assemblies, breathing circuits and related components include configurations for reducing condensation within the mask and/or inhibiting or preventing condensation from coming into contact with a user of the mask. The mask assemblies can incorporate heating elements (such as heating coils), insulating spaces or barrier layers.

  • Energy sensor
    Patent number: 6735379
    Abstract: A radiant energy sensor is adapted to detect radiant heat energy incident on a surface. The energy sensor has a body portion with a pair of sides. A temperature sensor is located on each side of the body portion. In use the body portion is mounted on the surface such that one of the sensors is located between the body portion and the surface, thereby being masked by the body portion from heat energy otherwise incident on the surface.

  • Energy sensor
    Publication number: 20030021596
    Abstract: A system for heating a patient using a radiant heater is disclosed. In order to ensure optimum positioning of the patient various location and indication embodiments are included. The present invention either adjusts the energisation of the heater to provide optimum heating, provides an indicator of the optimum position for the patient, indicates that the patient is not correctly positioned or any combination thereof. Variations of a sensor to detect the skin temperature and radiant energy incident thereon are also disclosed.
