Abstract: A gas compression and delivery device for treatment of sleep disorders. The device has a motor, at least one impeller, and two air pressure chambers, each receiving air at a different pressure, one pressure applied to a patient during inspiration and one for expiration. A mask having a dual pressure gas delivery hose and a selector for letting in either the high or low pressure gas depending on the breathing cycle of the patient. The gas pressures are adjustable by means of valves on the separate chambers in the device. At least one sensor on the patient sending data to a controller in the device as to the patient's physiological data which is used to determine the patients breathing treatment needs. The controller may be a microprocessor with memory capability to store patient data for diagnosis and treatment of the patient. Telecommunications by telemetry, or telephony to a remote site allows home use of the device rather than institutional use with health care providers on site.

Abstract: A device for reliably and non-invasively measuring respiration rates and effort by encircling the patient's chest with a device having a large section of inelastic belt attached to a small section of elastic material. The elastic material having two magnetic tapes with wire windings thereon proximate each other with an insulation material therebetween. The wire windings are electrically connected to each other. The magnetic tapes have opposite ends attached to the elastic material such that when the elastic material expands and contracts the wire windings move relative to each. A toroidal transformer is connected to the wire windings. When a carrier signal is introduced to the transformer and the magnetic tapes move relative to each other on the elastic material when the patient breathes a mutual inductance in the wire windings modulates the carrier signal and thus measures the expansion and contraction of the patient's chest which is directly related to the patient's respiration rate.
