A patient interface assembly adapted to be connected to a gas supply pump to deliver pressurized breathable gas to the inlet of a patient's respiratory system includes a patient interface structured to provide a seal with the patient and at least one inlet tube provided to the patient interface. Each inlet tube includes a substantially flat lower side wall to face the patient and a substantially arcuate upper side wall.

Patient interface assembly for CPAP respiratory apparatus

A patient interface assembly adapted to be connected to a gas supply pump to deliver breathable gas to the inlet of a patient's respiratory system comprises a supply conduit, a patient interface, a branch swivel connector including a Y-piece and an elbow that swivels relative to the Y-piece, the branch swivel connector being adapted to be located to the rear of a patient's head in use and being connected to the supply conduit. A pair of inlet tubes each have a first end positioned in use near a mouth of a patient and are connected to the nose mask, a middle portion arranged to pass across a cheek of a patient and an end portion being joined to the Y-piece of the branch connector. The inlet tubes have a flat configuration and are provided with a plurality of internal ribs which prevent the tubes being crushed. A strap is secured to the patient interface and adapted to pass around the sides and rear of the head to hold the patient interface in position on the head.

Patient interface for respiratory apparatus

Patients may operate a CAP system to deliver appropriate airway pressure at their home. A patient's apnea problem can be diagnosed at home without supervision with a CPAP device which delivers a continuously minimum appropriate pressure for substantially the entire period of therapy.

Method and apparatus useful in the diagnosis of obstructive sleep apnea of a patient

Patients may operate a CPAP system to deliver appropriate airway pressure at their home. A patient's apnea problem ca be diagnosed at home without supervision with a CPAP device which delivers a continuously minimum appropriate pressure for substantially the entire period of therapy.

A CPAP apparatus including: a variable pressured air source and means to vary the air pressure delivered therefrom; a nose piece for sealed air communication with a patient's respiratory system; an air communication line from the air source to the nose piece; a sound transducer adapted to be in sound communication with the patient's respiratory system; and a feedback system controlling the output pressure of the air source in response to an output from the transducer so as to increase the output air pressure from said air source, in response to detection of sound indicative of snoring, in accordance with a predefined procedure. The sound transducer, in its most general form, comprises a pressure transducer which, in addition to detecting snoring sounds, can detect other respiratory parameters such as the rate of breathing, inhaled air flow volume, and inhaled air flow rate. Output air pressure from air source is increased in response to one or more of these parameters in accordance with a pre-defined procedure.

Device for monitoring breathing during sleep and ramped control of CPAP treatment

Device and method for nonclinical monitoring of breathing during sleep, control of CPAP treatment and preventing apnea

A combination mouth and nasal mask (40) for assisted respiration or CPAP is disclosed. The combination mask (40) has a frame (42) to the rear side of which is mounted a separate nasal cushion (44) and mouth cushion (46). Both the nasal cushion (44) and the mouth cushion (46) separately form a rolled edge seal around the patient's face in the vicinity of the nose and in the vicinity of the lips. Inlet air is communicated from within the housing (48) to the mouth chamber, circumscribed by the mouth cushion (46) by means of one or more interconnecting tubes (62). The proportion of air communicated to the mouth chamber (48) is controlled by the sizing and number of the tube(s), thus providing for free flow of air, restricted flow of air and pressure equalization, or zero flow of air. A mouth mask (10) for assisted respiration or CPAP also is disclosed.

An air flow device and a method useful for the treatment of upper airway disordered breathing. The invention provides an airflow device having a means for delivering variable pressure levels of breathable air to a patient's respiratory system with a means for controlling the time during which the delivered pressurized air rises from an initial pressure level to a higher operating pressure level. The device increases the pressure level of gas delivered to the patient over a plurality of breaths taken by the patient. This type of device is useful for treating a wide variety of sleeping and breathing disorders.
