A system and method for sleep monitoring, diagnosing and sensing temperature and pressure for a breathing cycle of a patient including a sensing device suitable for both nasal and oral breath monitoring for measuring respiratory air wave and airflow information during a sleep apnea diagnostic session and processing the acquired air wave and airflow breathing information for input to conventional polysomnography equipment.

Adaptive temperature sensor for breath monitoring device

A cannula having at least three separate flow passages and comprising separate nasal and mouth main bodies. The nasal body has first and second nares and first and second main flow chambers respectively communicating with first and second ports, and the first and second flow chambers are separated from one another by a septum. The mouth main body is adjacent the nasal main body and has at least one mouthpiece and at least a third main flow chamber therein communicating with a third port. The cannula has at least first, second and third flow paths which can be connected with a desired supply, monitoring or detection device. The invention also relates to the method of manufacturing the cannula.

Nasal and oral cannula having three or more capabilities and method of producing same

A pressure sensing device for coupling to a cannula and receiving respiratory breathing information from a patient to be monitored. The pressure sensing device comprising an exterior housing accommodating a snore detection circuit which processes information and outputs a signal indicative; an airflow detection circuit which processes information and outputs a signal indicative thereof; and an internal test circuit for testing an integrity of the airflow and snore detection circuits prior to use of the pressure sensing device to ensure that both circuits are operational. An input port for pressure sensing device extends from the housing of the pressure sensing device so as to space a connector, for the cannula, a sufficient distance away from the bottom surface whereby the bottom surface will always remain flush with and in constant and continuous intimate contact with a support surface for the pressure sensing device.

Pressure sensing device with test circuit

Respiratory equipment coupled in interruptible fluid communication between a recipient and a source of pressurized respiratory gas and adapted for controlling delivery of the pressurized gas to the recipient as the recipient inhales and exhales. The equipment includes a supply valve and a sensing valve cooperable to intermittently deliver pressurized gas to the recipient responsive to the recipient's inhalation and exhalation. A regulator mechanism is disposed between and in fluid communication with the pressurized gas source and the supply valve. The equipment may include a control device for controlling flow of pressurized gas from the pressurized gas source to the supply valve and from the pressurized gas source to the regulator mechanism. The control device also controls the pressure of pressurized gas discharged by the regulator mechanism. At least one adjustable device limits movement of a sensing valve diaphragm member responsive to the recipient's inhalation.
