  • Patent number: 10485941
    Abstract: A system for enhancing secretion removal from an airway of a subject by applying a negative pressure to the airway of the subject just prior to an exsufflation is provided. The negative pressure is applied just after the subject has inhaled under his own power and/or just after generator mechanical insufflation by the system. The negative pressure applied just after inhalation/insufflation and just prior to exsufflation temporarily reduces the cross-sectional area of the airway of the subject. A reduced cross-sectional area User of the airway increases the velocity of air through the airway during a subsequent exsufflation, which results in enhanced secretion clearance. In some embodiments, the system includes one or more of a pressure generator, a subject interface, one or more sensors, a user control interface, one or more processors, and/or other components.

  • Patent number: 10478575
    Abstract: A method and a control program for operating an anesthesia apparatus, as well as an anesthesia apparatus (12), which operates according to the method are provided. The anesthesia apparatus includes a breathing gas feed unit (22) intended for displacing a breathing gas volume in a breathing circuit (10). A piston (23) brings about the displacement of the breathing gas. Switching over between a first mode of operation and a second mode of operation during the return of the piston (23) allows for a presetting of a corresponding piston return velocity. The piston return velocity depends on a volume flow in an exhalation branch (34) of the breathing circuit (10) in the first mode of operation. The piston return velocity depends on a minimally necessary piston return velocity in the second mode of operation.

  • Patent number: 10478586
    Abstract: Provided is a method that includes automatically providing air/oxygen at a pre-selected maximum pressure limit, breath volume and respiratory-rate. The pre-selected maximum pressure limit, breath volume, and respiratory-rate are automatically set as a function of a size of a mask coupled to an air/oxygen supply system. Further provided is a ventilator system that includes a ventilator mask, a ventilator supply system, and a mask conduit. The ventilator mask is configured in a size that will fit upon a selected range of sizes of human faces. The ventilator supply system includes an air/oxygen source and an air/oxygen regulator system configured to regulate air/oxygen flow parameters as a function of the size of the mask. The mask conduit is configured to couple the ventilator supply to the ventilator mask.

  • Patent number: 10441736
    Abstract: A respiratory mask can have a frame supporting a sealing arrangement. Various features of the frame and sealing arrangement can improve comfort and reduce the occurrence of pressure sores. The frame can include cheek supports that have a large surface area configured to spread loads over a greater area of the patient's face and therefore reduce the forces applied to the face and the occurrence of point loads. The seal can have a main body that includes a spring with a silicone skin, wherein the spring applies a substantially constant force to the face and/or nares of the patient.

  • Patent number: 10384023
    Abstract: A respiratory assistance device includes a patient interface for coupling to a patient respiratory passageway, and a selectively regulated therapeutic gas flow source in pneumatic communication with the patient over the patient interface. A ramping controller is connected to the therapeutic gas flow source and is receptive to inputs of a prescription pressure level, an initial pressure level, a total ramp duration, and a numeric value corresponding to a ramping duration. Therapeutic gas flow at an initial pressure level is regulated for a ramp delay duration reciprocal to the ramping duration relative to the total ramp duration. The ramping controller incrementally increases therapeutic gas flow to the prescription pressure level from a ramp start time to a ramp end time at a delivery pressure increase rate derived from the numeric value of the ramping duration and the total ramp duration.

  • Patent number: 10369320
    Abstract: 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.
