  • Patent number: 10441734
    Abstract: An inhaler comprising a source of inhalable composition. An outlet flow path is provided for the composition from the source to a composition outlet at an outlet end of the inhaler. Means are provided to generate a flow of composition from the source along the outlet flow path and out of the composition outlet when suction is applied to the outlet end. A pair of air outlets at the outlet end are arranged on opposite sides of the composition outlet through which air is drawn in respective air jets when suction is applied to the outlet end. The composition and air outlets are arranged such that, in use, the pair of air jets impinge on the composition plume.

  • Patent number: 10272222
    Abstract: This invention relates to a treatment device (10) and method of use, and in particular to a treatment device adapted to assist the clearance of bronchial secretions in persons whose cough function is impaired. The invention provides a treatment device having a pump (12) with a negative pressure inlet side (22) and a positive pressure outlet side (24). The device has a breathing tube (14) for connection to a patient, and a pressure sensor (18) adapted to determine the pressure within the breathing tube. A valve (16) selectively connects the breathing tube to the inlet side or the outlet side of the pump whereby to provide cycles of positive and negative pressure within the breathing tube. A controller (26) is provided to control the valve. An indicator (20) alerts the patient to an operational status of the device so that the patient can breathe in time with the device and in particular can seek to cough at the same time as the pressure within the breathing tube is rapidly reduced.

  • Patent number: 10252013
    Abstract: A respiratory device having a respiratory gas source, a control unit and a connecting device for connecting to a respiratory mask. The control unit is connected to a sensor for detecting a measurement parameter. The control unit has a step generator for specifying a stepped modification of the pressure that is generated by the respiratory gas source. The sensor measures a signal that corresponds to the pressure distribution and is coupled to an analyzer that evaluates the temporal distribution of an analysis signal that is dependent on the measuring signal. The step generator increases the pressure by a pressure step in a respiratory cycle that follows the measuring evaluation, if the analyzer determines a deviation of the analysis signal from a limit value after a predeterminable time limit has elapsed following the pressure increase. The deviation must exceed a predeterminable minimum differential in order to trigger a pressure increase.

  • Patent number: 10207069
    Abstract: Systems and methods for compensating for leaks in a ventilation system based on data obtained during periods within a breath in which the patient is neither inhaling nor exhaling. The methods and systems described herein more accurately and quickly identify changes in leakage. This information is then to estimate leakage later in the same breath or in subsequent breaths to calculate a more accurate estimate of instantaneous leakage based on current conditions. The estimated leakage is then used to compensate for the leak flow rates, reduce the patient's work of breathing and increase the patient's comfort (patient-ventilator breath phase transition synchrony).
