  • Patent number: 10803983
    Abstract: A system and method for auto-regulating therapeutic administration to a patient for achieving artificial homeostasis. The system includes a plurality of modules designed to create an automated therapeutic administration system. An auto-regulation module maintains a target vital level within a patient by comparing measured levels with stored target levels; a delivery module delivers an amount of a therapeutic to a patient based on instructions from the auto-regulation module, and a sensor module measures patient levels and transmits the measurements to the auto-regulation unit. The auto-regulation module compares the measured levels with the stored target levels, and, based on the comparison, instructs the delivery module to alter the amount of therapeutic administered to the patient, in an effort to match the measured levels with the target levels, thereby creating a closed feedback loop designed to achieve an artificial homeostasis for a patient.

  • Patent number: 10751491
    Abstract: A ventilator that delivers air at different pressures to a patient during inspiratory and expiratory cycles of breathing and that cycles from inspiratory to expiratory operation when the patient's respiratory flow passes a threshold level. The threshold generally increases from the beginning of inspiration to the end of inspiration. The increase can be linear over all or only a portion of the inspiratory cycle, and the threshold can be adjusted so that cycling is prevented during the initial portion of an inspiratory cycle. The minimum and maximum levels may both be functions of peak flow and the threshold may increase as a function of elapsed inspiratory time. The rate at which the threshold increases from a minimum level to a maximum level may be adjustable for individual patient needs and may be determined from previous breaths.

  • Patent number: 10675424
    Abstract: A respiratory treatment apparatus and method in which a leak is determined by using an averaging window. The window starts at the present time and extends back in time to a point determined according to a current one of progressively detected phase measures of a first respiratory cycle and a corresponding phase measure attributable to a preceding second respiratory cycle. In another aspect, a jamming index indicates whether the leak is rapidly changing. To the extent that jamming is high, the leak estimate used progressively changes from that using sliding breath-window averaging to a more robust and faster responding low-pass filter method, and adjustment of ventilatory support based on measures employing estimated respiratory flow is slowed down or stopped.

  • Patent number: 10315002
    Abstract: A method of providing a breath to a human patient. The patient has a patient connection connected, by a patient circuit, to a ventilator having a first ventilator connection and a different second ventilator connection. Each of the first and second ventilator connections are in fluid communication with the patient circuit. The method includes identifying, with the ventilator, initiation of an inspiratory phase of the breath, delivering a bolus of oxygen to the first ventilator connection before or during the inspiratory phase, and delivering breathing gases comprising air to the second ventilator connection during the inspiratory phase. The ventilator isolates the bolus of oxygen delivered to the first ventilator connection from the breathing gases delivered to the second ventilator connection.

  • Patent number: 10245400
    Abstract: A portable handheld pressure support system (10) is configured to provide pressure support therapy to a subject. The pressure support system provides a pressurized flow of breathable gas that is delivered to the airway of the subject to treat COPD and/or dyspnea, hyperinflation, and/or other conditions. The system is configured to adjust an expiratory pressure level of the pressure support therapy responsive to identification of hyperinflation in the subject. The pressure support therapy provided to the subject is configured to be used as needed to rapidly alleviate shortness of breath, hyperinflation, and/or other symptoms. The pressure support system is configured to be small and lightweight so that the subject may carry the system and use the system as needed.

  • Patent number: 10245406
    Abstract: A method of providing a breath to a human patient having a patient connection connected by a patient circuit to a ventilator device. The method includes delivering both a bolus of oxygen and breathing gases including air to the patient circuit. The patient circuit conducts the bolus of oxygen and the breathing gases to the patient connection. The breathing gases are delivered before an end of the inspiratory phase of the breath. The bolus may be delivered at or before a beginning of an inspiratory phase of the breath, and the delivery of the bolus may be terminated before the end of the inspiratory phase of the breath. The bolus and breathing gases are delivered to the patient circuit via different ventilator connections that isolate the bolus from the breathing gases before they enter the patient circuit.

  • Patent number: 10238822
    Abstract: A PAP system is adapted for treatment of respiratory disease or sleep disordered breathing. The PAP system includes headgear, a patient interface and a flow generator. The flow generator includes a blower adapted to provide pressurized breathable gas to a patient through the patient interface. The blower is at least partially vibrationally isolated from the patient's head by at least one foam layer mounted within the flow generator to secure the blower. The at least one foam layer is adapted to reduce the amount of transmitted vibration received by the patient. The flow generator further includes a mounting structure limiting an extent of a compression of the at least one foam layer due to the weight of the blower. The mounting structure includes at least one protrusion extending from an interior surface of the flow generator toward the blower.
