摘要： A respiratory flow therapy apparatus including a sensor module can measure a flow rate of gases or gases concentration provided to a patient. The sensor module can be located after a blower and/or mixer. The sensor module can include at least an ultrasonic transmitter, a receiver, a temperature sensor, a pressure sensor, a humidity sensor and/or a flow rate sensor. The receivers can be immersed in the gases flow path. The receivers can cancel delays in the transmitters and improve accuracy of measurements of characteristics of the gases flow. The receivers can allow for detection of a fault condition in a blower motor of the apparatus.

摘要： A sealing interface forms part of an apparatus for supplying a flow of respiratory gases to a user. The sealing interface comprises a foam or gel inner cushion and a thin resilient rubber outer sheath. A face side of the inner cushion resiliently supports the outer sheath. The inner cushion has a toothed profile formed on the face side of the inner cushion. The toothed profile consists of at least one tooth having an apex on the perimeter of the inner cushion. The apex is positioned between two valleys in the perimeter of the inner cushion. In use the apex of each tooth of the toothed profile is in supporting contact with the outer sheath.

摘要： Medical breathing tubes have a tubular body that defines a lumen extending between open terminal ends of the tubular body. An internal form is enclosed within the lumen and supportive of the tubular body. The internal form may be a coated encapsulated internal form where the coating secures the internal form to the tubular body. The internal form may provide for a series of alternative crests and troughs of the tubular body. A patient interface and/or a securement system may be attached to the tubular body.

摘要： A blower unit for use as part of an integrated blower/humidification system is described. The blower unit has an outer casing, which encloses and forms part of the blower unit, the casing including an air inlet vent. The blower unit further includes a humidifier compartment for receiving a humidifier unit with a separate gases inlet and outlet, the compartment having a heater base for heating the contents of the humidifier unit. The compartment also has a blower inlet port which aligns with the humidifier unit inlet in use, the blower providing a gases path through the casing between the inlet vent and the inlet port. The blower unit also includes a fan for providing a pressurised gases stream along the gases path, and a power supply unit for powering the fan. The gases path is routed over the power supply unit in order to provide a cooling air flow.

摘要： A breathing circuit for delivering heated, humidified gases to a patient for medical purposes is described, comprising a humidifier chamber holding a quantity of water, a blower unit that delivers a pressurized gases stream to the chamber inlet, and a control system that adjusts output parameters of the breathing circuit, the circuit including a heater plate which heats the water in the chamber so that gases flowing through the chamber become heated and humidified, the circuit also including a gases transportation pathway and patient interface to convey heated humidified gases to a patient, the gases transportation pathway including an RFID tag located at the patient end which senses a parameter of the gases passing through the pathway, the control system including an RFID interrogator interrogating and receiving data relating to the sensed parameter from the RFID tag in real time, and adjusting the output parameters of the breathing circuit accordingly.

摘要： An interface for positive pressure therapy includes a mask assembly. The mask assembly includes a mask seal that is adapted to underlie the nose. The mask seal extends up the lateral sides of the nose. The mask seal has a primary seal below the nose and a secondary seal alongside the nose. The mask seal includes a rolling hinge that permits one portion of the mask seal to deform relative to another portion of the mask seal. In one configuration, the portion of the mask seal that underlies the nose is configured to deform relative to a lower portion of the mask seal.
