  • Patent number: 10709859
    Abstract: We disclose a mask for administering a breathable gas to a patient, which comprises a mask body and a gas flow disrupter joined to the mask body for generating a turbulent gas plume rearwardly towards the nose and mouth of the patient. The mask body is configured to position the flow disrupter so as to be spaced from and opposing the patient's nose and mouth region when the mask is worn by the patient. The mask includes a gas inlet for admitting gas from an external source into the mask interior, through the gas flow disrupter. The gas flow disrupter can be configured to generate a turbulent gas plume wherein the velocity of gas exiting the disrupter is approximately the same as the gas velocity entering the mask from the gas inlet.

  • Patent number: 10709910
    Abstract: In a preferred embodiment, methods and systems for the control of the breathing gas supply from a pressure-leading supply conduit to one or more breathing masks of an oxygen emergency supply device in a passenger aircraft include an on/off valve arranged between the supply conduit and the one or more breathing masks. The valve can be blocked or released to control air supply based upon monitoring mass flow to the breathing masks. The valve, for example, is actuated to an open position until the error between the actual mass flow and a desired mass flow exceeds a maximal error value, whereupon the valve is actuated to a closed position until the error between the actual mass flow and the desired mass flow exceeds a minimal error value whereupon the valve is actuated to the open position and the mass flow monitoring cycle is repeated.

  • Patent number: 10682476
    Abstract: A dry powder inhaler includes a powder storage element configured to hold a powdered medicament and an inlet channel receives powdered medicament from the powder storage element that is entrained in an airflow. The inlet channel has a first diameter and defines an opening. The inhaler includes a dispersion chamber that receives the airflow and the powdered medicament from the opening. The dispersion chamber has a second diameter. The inhaler includes an actuator housed within the dispersion chamber. The actuator oscillates within the dispersion chamber when exposed to the airflow to deaggregate the powdered medicament entrained by the airflow passing through the dispersion chamber. A ratio between the first diameter and the second diameter is between about 0.40 and 0.60 such that an audible sound is produced as the actuator oscillates. The inhaler includes an outlet channel through which the airflow and powdered medicament exit the inhaler.

  • Patent number: 10667748
    Abstract: A system and method configured to control pressure during enhanced cough flow of a subject are provided. A pressure regulator is operated such that during an individual exhalation of the subject, the pressure regulator is toggled between a first mode in which a subject interface is closed such that substantially no gas is communicated with the airway of the subject there through and a second mode in which the subject interface is opened to cause a series of exsufflation events for the individual exhalation of the subject. The pressure relief valve is associated with the subject interface and configured to open and release gas out of the subject interface, responsive to pressure within the subject interface exceeding a predetermined threshold value so as to maintain the pressure within the subject interface within a predetermined pressure range during the enhanced cough flow.
