Apparatus for generating a supply of air at positive pressure for the amelioration or treatment of a respiratory disorder includes a first chamber, a second chamber, at least one inlet tube structured and configured to allow ambient air to enter the first chamber, at least one flow tube structured and configured to allow air to pass from the first chamber to the second chamber, and a blower structured and configured to produce a flow of air at positive pressure. The blower is positioned in the first chamber and structured and configured to receive air from the second chamber. The blower includes a housing structured and configured to sealingly separate air flow through an interior of the housing from the first chamber. The at least one inlet tube is axially spaced from the at least one flow tube.

Respiratory pressure therapy device

A respiratory pressure therapy (RPT) system may include a housing portion forming a plenum chamber pressurizable to a therapeutic pressure; a seal-forming structure constructed and arranged to with a region of the patients face; a positioning and stabilising structure constructed and arranged to provide an elastic force to hold the seal-forming structure in a therapeutically effective position on the patients head; a blower configured to pressurize the plenum chamber to the therapeutic pressure; a vent assembly configured to discharge gas from a plenum chamber to atmosphere; a sensor port positioned downstream of the vent assembly such that the sensor port is in pneumatic communication with the air within the plenum chamber in any position of the vent assembly; and a sensor in pneumatic communication with the air within the plenum chamber via the sensor port.

Respiratory pressure therapy system

A PAP system for delivering breathable gas to a patient includes a flow generator to generate a supply of breathable gas to be delivered to the patient; a humidifier including a heating plate to vaporize water and deliver water vapor to humidify the supply of breathable gas; a heated tube configured to heat and deliver the humidified supply of breathable gas to the patient; a power supply configured to supply power to the heating plate and the heated tube; and a controller configured to control the power supply to prevent overheating of the heating plate and the heated tube.

Wire heated tube with temperature control system, tube type detection, and active over temperature protection for humidifier for respiratory apparatus

A respiratory apparatus includes components to protect operations of the apparatus. For example, in some versions, the apparatus may include a power supply, a motor powered by the power supply, and a transient absorption diode circuit between the motor and the power supply. The transient absorption diode circuit may be configured to absorb energy generated by the motor from rotational kinetic energy. Such absorption may serve to protect the components of the apparatus. In some examples, the apparatus may include a fault mitigation integrated circuit (IC). The IC circuit may be included in the respiratory apparatus to detect one or more faults based on physical and system parameters of the apparatus. The fault mitigation integrated circuit may generate a signal to stop the motor based on the detected fault, and may digitally communicate with a processor information about the detected fault.

Motor drive system for respiratory apparatus

A heated conduit is configured to connect to and receive pressurized breathable gas from a respiratory unit. The heated conduit includes a first cuff that includes an air inlet portion and an electrical connector portion that is adjacent the air inlet portion and comprises three electrical terminals that are configured to engage a respiratory unit electrical connector. The heated conduit also includes a second cuff comprising an air outlet and a flexible tube portion with a first end connected to the first cuff, a second end connected to the second cuff, and a spiral rib structure wrapped around a central lumen. A grouping of wires is supported within the spiral rib structure of the flexible tube portion and include a pair of heating wires and a signal wire. A sensing device extends into the gas flow path from an interior surface of the second cuff and is configured to output a signal indicative of the condition inside the heated conduit.

A flow generator includes a blower, a flow generator outlet configured to receive an end of a gas delivery tube, and a controller. The flow generator outlet includes electrical connectors configured to contact corresponding electrical connectors associated with the breathable gas delivery tube when the breathable gas delivery tube is received by the flow generator outlet. The controller includes a tube-type detect circuit and is configured to receive signals from the breathable gas delivery tube by way of the electrical connectors of the flow generator outlet. The tube-type detect circuit is configured so that when the breathable gas delivery tube is received by the flow generator outlet, the tube-type detect circuit determines the type of breathable gas delivery tube based on signals from the electrical connectors of the flow generator outlet that are indicative of a condition of a resistor associated with the breathable gas delivery tube.

A blower comprises a housing, an inlet to receive air, an outlet to deliver a flow of air and a deformable member configured to pump a chamber. The deformable member may be configurable to a first configuration and a second configuration, for example by electrical energy that may be applied as current or voltage. The blower may comprise a plurality of chambers, wherein each chamber may be compressed out of phase with each other, for example such that the flow rate of the generated air flow may not fluctuate as much. In other forms, the blower may comprise a plurality of chambers that vary in size.
