Patent number: 9415183Abstract: A mask for achieving positive pressure mechanical ventilation (inclusive of CPAP, ventilator support, critical care ventilation, emergency applications), and a method for a operating a ventilation system including such mask. The mask includes a piloted exhalation valve that is used to achieve the target pressures/flows to the patient. The pilot for the valve may be pneumatic and driven from the gas supply tubing from the ventilator. The pilot may also be a preset pressure derived in the mask, a separate pneumatic line from the ventilator, or an electro-mechanical control. The mask of the present invention may further include a heat and moisture exchanger (HME) which is integrated therein.Type: GrantFiled: August 28, 2014Date of Patent: August 16, 2016Assignee: Breathe Technologies, Inc.Inventors: Todd Allum, Enrico Brambilla, Joseph Cipolloone

Patent number: 9399109Abstract: A respiratory assistance device is disclosed. There is a variable speed blower with an output, and a patient ventilation interface configured for fitment on a patient respiratory passageway. A gas passage conduit couples the output of the blower to the patient ventilation interface. A pilot line from the gas passage conduit is coupled to a piloted exhalation valve of the patient ventilation interface. A pressure sensor measures a mask pressure in the patient ventilation interface, and a blower speed sensor measures a speed of the blower. A pressure controller in communication with the pressure sensor and the blower speed sensor detects a patient inspiratory phase and a patient expiratory phase from at least one of the measured speed of the blower and a set speed of the blower. The pressure controller adjusts an operating speed of the blower and actuates the piloted exhalation valve based upon the measured mask pressure.Type: GrantFiled: October 22, 2012Date of Patent: July 26, 2016Assignee: Breathe Technologies, Inc.Inventors: Leonardo Alberto Baloa Welzien, Enrico Brambilla, Samir S.

Patent number: 9038635Abstract: The disclosure is directed to various tubing arrangements and an associated Y-connector which may be used to facilitate the operative interface of the mask to a ventilator within a ventilation system. The tubing arrangement may comprise a pair of bi-lumen tubes. One end of each of the bi-lumen tubes is fluidly connected to the mask, with the opposite end being fluidly connected to the Y-connector. The Y-connector is in turn fluidly connected to one end of either a tri-lumen tube or a quad-lumen tube also included in the tubing arrangement, the opposite end of such tri-lumen tube or quad-lumen tube being fluidly connected to the ventilator. The Y-connector is uniquely configured to fluidly connect certain lumens of the tri-lumen tube or the quad-lumen tube to dedicated, corresponding ones of the lumens included in respective ones of the bi-lumen tubes, and to further allow for the selective detachment of the tri-lumen tube or the quad-lumen tube from the bi-lumen tubes.Type: GrantFiled: March 13, 2013Date of Patent: May 26, 2015Assignee: Breathe Technologies, Inc.Inventor: Enrico Brambilla

Patent number: 8985108Abstract: Indicating fit status of a mask in communication with a respiratory assistance device is disclosed. Upon initiating a therapeutic gas delivery from the respiratory assistance device to the mask, one or more measurements from respective one or more sensors of the respiratory assistance device is received. A leakage value from these measurements is derived, and a mask fit index is assigned. This is based at least upon a correlation of the leakage value to a particular sub-range of predetermined leakage values that corresponds to the mask fit index. The particular sub-range of predetermined leakage values is one among a plurality of sub-ranges, which together comprises an overall mask fit range defined at least by an ideal mask fit region, a loose mask fit region, and a tight mask fit region. A mask fit status based upon the assigned mask fit index is output to an indicator interface.Type: GrantFiled: April 6, 2012Date of Patent: March 24, 2015Assignee: Breathe Technologies, Inc.Inventors: Samir S.

Publication number: 20140373835Abstract: In accordance with the present invention, there is provided is provided a tubing arrangement and associated connectors, including a delivery adaptor and a Y-connector, which may be used to facilitate the operative interface of a patient interface to a ventilator within a ventilation system. The delivery adaptor is connected between the outlet connector of the flow generator and the main delivery tube (i.e., the quad-lumen tube) in the ventilation system. The delivery adaptor functions to retain the pneumatic isolation of a sense line of the ventilation system from certain other lumens of the quad-lumen tube, and further connects one of the small lumens of the quad-lumen tube to an external oxygen source or an external humidification source. The oxygen or humidification is delivered to such lumen through the adaptor. The oxygen or humidification is then bled into the air stream at the outlet of such lumen which is at the Y-connector.Type: ApplicationFiled: June 25, 2013Publication date: December 25, 2014Inventors: Samir S.
