  • Patent number: 10046133
    Abstract: A system for providing ventilation support to a patient may include a ventilator, a control unit, a gas delivery circuit with a proximal end in fluid communication with the ventilator and a distal end in fluid communication with a nasal interface, and a nasal interface. The nasal interface may include at least one jet nozzle at the distal end of the gas delivery circuit; and at least one spontaneous respiration sensor for detecting respiration in communication with the control unit. The system may be open to ambient. The control unit may receive signals from the at least one spontaneous respiration sensor and determine gas delivery requirements. The ventilator may deliver gas at a velocity to entrain ambient air and increase lung volume or lung pressure above spontaneously breathing levels to assist in work of breathing, and deliver ventilation gas in a cyclical delivery pattern synchronized with a spontaneous breathing pattern.

  • Patent number: 9962512
    Abstract: A system for supplying ventilatory support may include a nasal interface configured to communicate with a patient's nose while allowing the patient to breathe ambient air directly without flowing through the nasal interface. A nozzle may be associated with the nasal interface at a distance from a nose. The nozzle may be connectable to the gas delivery circuit and the gas delivery source. The nozzle may be capable of delivering gas into the nasal passage by creating negative pressure area near the nozzle and a positive pressure area near the entrance to the nose. A combination of gas from the gas delivery source and air entrained from the gas exiting the nozzle may provide ventilatory support.

  • Patent number: 9919124
    Abstract: 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.

  • Patent number: 9833584
    Abstract: A patient ventilator secretion management system is disclosed. The system has a valve with an input in pneumatic communication with a therapeutic breathing gas source. The valve has variable positions, each of which corresponds to a specific flow rate of gas being output therefrom. A patient ventilation interface is in pneumatic communication with the valve over a gas delivery circuit. A controller in communication with the valve regulates the position thereof. The controller sequentially switches the valve from one of the variable positions to another to output a first range of fluctuating flow rates of gas for delivery to the patient ventilation interface during at least a selected one of patient expiratory and inspiratory phases.

  • Patent number: 9757532
    Abstract: Methods for detecting a patient disconnecting from a continuous positive airway pressure (CPAP) therapy device are disclosed. A cyclical pressure difference signal is derived based upon measurements from a patient interface pressure sensor and from a source pressure sensor. The pressure difference signal is integrated to generate a resultant integral signal for each respiratory cycle, which is comprised of at least one inspiratory phase and at least one expiratory phase as represented by the corresponding portions of the pressure difference signal. A pressure source of the CPAP therapy device is deactivated in response to a disconnect condition being evaluated from the integral signal. In one embodiment, the disconnect condition is the integral signal exceeding a predefined disconnect threshold. In other, it is a slope value corresponding to a rate of increase of the integral signal exceeding a predefined threshold for a predefined duration.

  • Patent number: 9731089
    Abstract: A method for detecting sleep for continuous positive airway pressure (CPAP) therapy is disclosed. Discrete values of a control signal generated by a pressure controller to regulate delivered pressure at the patient are measured over a predefined time window encompassing one or more respiratory cycles. A baseline control signal value is generated from a weighted average of the measured discrete values of the control signal. Estimates of a respiratory cycle period, an inspiration control time, and an expiration control time are then generated. Estimates of one or more secondary control signal properties for each of the respective inspiration control time and expiration control time are generated. Pressure to the patient is increased in response to an evaluation of the estimates of the one or more secondary control signal properties being indicative of the patient reaching a sleep state.

  • Patent number: 9724017
    Abstract: A single respiratory cycle flow limitation detection method is disclosed. A patient gas delivery signal is received from one or more sensors in pneumatic communication with a ventilation source and a patient ventilation interface to a patient airway. The patient gas delivery signal is representative of a measure of therapeutic gas being delivered to the patient airway at a given time instant, and spans the single patient respiratory cycle. A second derivative of the patient gas delivery signal is generated and a total number of zero crossings therein are counted. These zero crossings are representative of an inflection change in the patient gas delivery signal. A flow limitation indication corresponding to the identified flow limitation is generated when there are at least two zero crossings in the second derivative of the patient gas delivery signal. An angle of deformation representing early, late, or mid-cycle obstruction onsets is generated.

  • Patent number: 9669173
    Abstract: Adapting a patient to an airway pressure support therapy is disclosed. An initial prescription pressure level is derived from a respiratory disturbance index diagnosis. A pressure ramping slope is generated from the initial prescription pressure level and a received initial pressure level. Increasing levels of pressure are delivered to the patient as defined by the pressure ramping slope. The pressure ramping slope is adjusted based upon derived usage duration trends, and the prescription pressure level is adjusted based upon measured apnea/hypopnea index variations resulting from the delivered increasing levels of pressure to the patient.

  • Patent number: 9668692
    Abstract: The identification of obstructed breathing, including an apnea condition and a hypopnea condition, is disclosed. A signal representative of a flow rate of therapeutic gas being delivered to the patient is received. A peak flow value and a minimum flow value over a predetermined time window encompassing a plurality of respiration cycles is derived. A polynomial difference equation from the peak flow values and the minimum flow values is generated, and a respiration index from a minimum of the polynomial difference equation is derived. The apnea and/or hypopnea condition is indicated based upon a comparison of the respiration index to a predefined obstruction threshold over a predefined obstruction time period.

  • Patent number: 9399109
    Abstract: 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.
