Modular ventilatory support systems and methods are disclosed in which a user may transition the system between a stationary configuration, an extended range configuration, and a stand-alone configuration. The modular components of the system include a compressor unit, a ventilator which may dock with the compressor unit, and a patient interface which may be connected to either the compressor unit or the ventilator unit. By rearranging these modular components into different configurations, mobility and duration of use may be optimized to fit the present needs. In the stationary configuration, mobility is most restricted, but duration of use is maximized. In the extended range configuration, mobility is enhanced, with duration of use limited by the battery power of the ventilator. In the stand-alone configuration, mobility is maximized, with duration of use limited by battery power of the ventilator and the quantity of an external gas supply.

Modular ventilation system

A patient circuit of a ventilation system, such as a non-invasive open ventilation system, wherein the patient circuit comprises a nasal pillows style patient interface that incorporates at least one 'Venturi effect' jet pump proximal to the patient. The patient circuit further comprises a pair of uniquely configured 3-way connectors which, in cooperation with several uniquely configured tri-lumen tubing segments, facilitate the cooperative engagement of the patient interface to a ventilator of the ventilation system.

Patient interface with integrated jet pump

A mask system includes a frame adapted to attach headgear, a sealing arrangement releasably connectable to the frame, and an elbow provided to the sealing arrangement and adapted to be connected to an air delivery tube that delivers breathable gas to the patient. The sealing arrangement defines a breathing chamber and is adapted to form a seal with the patient's face. The sealing arrangement includes structure to establish a positive connection with the frame and with the elbow.

Mask system

An apparatus to treat, inhibit, or prevent an eye condition in a patient can include a cover, sized and shaped to fit over an eye of a patient to define a cavity between the cover and an anterior surface of the eye when the cover is located over the patient eye. The apparatus can include a pressure source, in communication with the cavity, capable of applying non-ambient pressure in the cavity. The apparatus can include control circuitry, in communication with the pressure source, configured to vary non-ambient pressure applied to the cavity to affect a targeted pressure relationship between an indication of a first physiological pressure level and a second physiological pressure level associated with the eye of the patient.

Apparatus and methods to adjust ocular blood flow

An oxygen concentrator includes one or more adsorbent sieve beds operable to remove nitrogen from air to produce concentrated oxygen gas at respective outlets thereof, a product tank fluidly coupled to the respective outlets of the sieve bed(s), a compressor operable to pressurize ambient air, one or more sieve bed flow paths from the compressor to respective inlets of the sieve bed(s), a bypass flow path from the compressor to the product tank that bypasses the sieve bed(s), and a valve unit operable to selectively allow flow of pressurized ambient air from the compressor along the one or more sieve bed flow paths and along the bypass flow path in response to a control signal. The valve unit may be controlled in response to a command issued by a ventilator based on a calculated or estimated total flow of gas and entrained air or % FiOof a patient.

O2 concentrator with sieve bed bypass and control method thereof

A portable oxygen concentrator retrofit system and method in which an existing portable oxygen concentrator may be retrofitted to output an enriched oxygen gas at a flow rate suitable for use in a patient ventilation system without the need for an external source of compressed gas.

Portable oxygen concentrator retrofit system and method

Oconcentrator with sieve bed bypass and control method thereof

A head-mountable flow generator is configured to deliver a flow of breathable gas at a continuously positive pressure with respect to ambient air pressure to a patient interface in communication with an entrance to a patient's airways including at least an entrance of the patient's nares, while the patient is sleeping, to ameliorate sleep disordered breathing. The flow generator includes a motor, an impeller assembly and housing that encases the motor and the impeller assembly. The housing is configured to be mounted on the patient's head and comprises an inlet to receive the flow of breathable gas and a pair of opposing outlets to deliver the flow of breathable gas. In addition, the impeller assembly is configured to pressurize the flow of breathable gas received from the inlet, and the housing is configured to convey the pressurized flow of breathable gas through both outlets.

Respiratory apparatus

A patient interface assembly includes a flexible cushion configured to sealingly engage the patient's nares and a frame with a pair of flexible extending members that extend laterally from opposite sides of the frame. The frame and the flexible cushion together form a chamber. The patient interface assembly also includes a positioning and stabilising structure configured to maintain the flexible cushion in engagement with the patient's nares. The positioning and stabilizing structure has a pair of headgear straps. Each headgear strap is connected to a respective one of the flexible extending members. The flexible extending members do not form an airflow path for the breathable gas. The headgear straps have a multi-layered structure, at least one layer being made of fabric and at least one layer being made of plastic. In addition, the at least one plastic layer is a rigidizer that adds rigidity to the respective headgear strap.

Unobtrusive interface system

A continuous positive airway pressure (CPAP) apparatus for respiratory assistance of a patient is disclosed. There is a blower having an output connectible to a ventilation mask wearable by the patient. A first pressure sensor measures blower pressure at the output of the blower, and a second pressure sensor that is connectible to the ventilation mask measures mask pressure therein. A pressure controller is connected to the first pressure sensor and the second pressure sensor, and a patient inspiratory phase and a patient expiratory phase is be detectable by the pressure controller to regulate therapeutic airflow delivered to the patient based upon pressure differentials between the mask pressure and the blower pressure.
