  • Pressure adjustment method for CPAP machine
    Patent number: 9339619
    Abstract: A positive airway pressure apparatus is automatically adjusting. Pressure increases in response to apnea events when the apparatus is in one or more responsive states. Pressure does not increase in response to apnea events when the apparatus is in a non-responsive state. The apparatus switches between responsive and nonresponsive states depending upon any of a number of different criteria that help differentiate between open airway apnea events and closed airway apnea events.

  • Breathing assistance apparatus
    Patent number: 9289571
    Abstract: Breathing assistance apparatus includes a gases supply unit adapted to, in use, deliver a stream of pressurised gases from an outlet. The gases supply unit is adapted to vary the pressure of the stream of pressurised gases. A supply path includes a flexible self-supporting gases transportation pathway having a first end connected to the outlet so that the gases transportation pathway receives the stream of gases and conveys the gases to a patient. A patient interface is connected to the second end of the gases transportation pathway receives a stream of gases. At least one sensor measures at least one information parameter of the supply path. A control system associated with the gases supply unit receives the information parameter. The control system contains reference data, and compares the received data to reference data, and determines a supply path based on the comparison.

  • HEADGEAR FOR BREATHING MASK
    Publication number: 20160067441
    Abstract: An interface assembly includes an interface, such as a mask, that is secured to a head using a headgear assembly. The headgear assembly can include at least one halo portion and a plurality of straps. The headgear assembly can include both a front halo portion and a rear halo portion. In some arrangements, the headgear and mask define an adjustable closed loop. In some arrangements, the headgear can include one or more rigid portions that contact the user's face to at least partially isolate a seal of the mask from tightening forces applied to the headgear. In some arrangements, the mask is an oral-nasal mask and the headgear applies a force to the mask comprising an upward force component. In some arrangements, the headgear can be contoured to the user's head.

  • Apparatus for measuring properties of gases supplied to a patient
    Patent number: 9265902
    Abstract: The gases temperature supplied to a patient when the patient is undergoing treatment such as oxygen therapy or positive pressure treatment for conditions such as Obstructive Sleep Apnea (OSA) or Chronic Obstructive Pulmonary Disease (COPD) is often measured for safety and to enable controlling of the humidity delivered to the patient. The apparatus is related to measurement of properties, particularly temperature (thermister 23), of gases flowing through a heated tube (3), supplying gases to a patient, which utilizes the heating wire (21, 28) within the tube.
