摘要:
The invention relates to a gas regulating valve (1) for a respiratory system comprising: —a main path between an inlet (2) and an outlet (3), and —an evacuation path between the outlet (3) and an evacuation orifice (4), characterized in that: —the main path is provided with at least a non-return valve for preventing gas to circulate from the outlet (3) to the inlet (2), and —the evacuation path is provided with an obstructing membrane (10) arranged and designed for being deformed by gas from the inlet (2) to partially or fully obstruct the evacuation path. The invention also relates to a mask integrating such gas regulating valve, and to a respiratory system also comprising such gas regulating valve.
摘要:
A breathable gas inlet control device permits flow regulation at the inlet of a flow generator for a respiratory treatment apparatus such as a ventilator or continuous positive airway pressure device. The device may implement a variable inlet aperture size based on flow conditions. In one embodiment, an inlet flow seal opens or closes the inlet to a blower in accordance with changes in pressure within a seal activation chamber near the seal. The seal may be formed by a flexible membrane. A controller selectively changes the pressure of the seal activation chamber by controlling a set of one or more flow control valves to selectively stop forward flow, prevent back flow or lock open the seal to permit either back flow or forward flow. The controller may set the flow control valves as a function of detected respiratory conditions based on data from pressure and/or flow sensors.

Disclosed is a breathing assistance system (10) comprising: a ventilator (12), a breathing lumen (14) arranged to communicate a flow of air between the ventilator and a tracheostomy tube (16) in the trachea of a patient, and a sensor (24) configured to generate a vibration signal representing vocal cord vibrations of the patient. The system is configured to facilitate the flow of exhaled air to the atmosphere via the upper airway of the patient in response to detection in the vibration signal of speech or attempted speech by the patient.

摘要:
The invention relates to a breathing assistance device for a patient (P), the device including: -a source of respiratory pressurized gas (S), a gas transmission duct (31) comprising a distal end (31d) coupled to said source and a proximal end (31p) coupled to the patient, -a gas regulating valve (32, 50) interposed in the gas transmission duct at a proximal location, comprising a leakage orifice (531) and an obstruction means (54) capable of varying the opening of the leakage orifice upon signal of controlling means (35) and allowing a bidirectional gas flow through the leakage orifice in both expiration and inspiration phases.
摘要:
A respiratory device, such as a ventilator, for use in treating respiratory disorders and for preventing respiratory disorders. The respiratory device is configured to be powered from a range of different power sources including an internal battery, an external battery, AC power source or a DC power source. The device may be electrically connectable to a plurality of external batteries in a series and the power from each external battery is used sequentially along the series. A controller of the respiratory device is configured to detect the connection of the different power sources and control use of the different power sources using a power priority scheme. The controller may determine an estimate of the total available battery capacity from all the electrically connected batteries and display the total battery capacity on a user interface display of the device.
摘要:
A respiratory treatment apparatus configured to provide a flow of breathable gas to a patient, including a breathable air outlet (16), an outside air inlet (34), and a pneumatic block module (56), wherein the pneumatic block module includes: a volute assembly (108) including an inlet air passage, a mount for a blower and an outlet air passage; the blower being mounted in the mount such that an impeller of the blower is in a flow passage connecting the inlet air passage and the outlet air passage; a casing enclosing the volute assembly, wherein air passages within the casing connect air ports on the volute assembly, wherein the inlet air passage of the volute assembly is in fluid communication with the outside air inlet and the outlet air passage of the volute assembly is in fluid communication with the air outlet.
