Abstract
An apparatus for treating a respiratory disorder in a patient, includes a respiratory pressure therapy device that generates a flow of air at positive pressure for treating the respiratory disorder. An air circuit transports the flow of air generated by the respiratory pressure therapy device to a patient interface. A nebuliser module is located at or adjacent to a proximal end of the air circuit to nebulise a liquid to form a nebula of the liquid. The nebula is admitted into the flow of air generated by the respiratory pressure therapy device. A vaporiser is located at the distal end of the air circuit to receive and vaporise the nebula to form a humidified flow of air.
Claims20
A respiratory treatment system for providing a flow of air at positive pressure to a patient for treatment of sleep disordered breathing, the system comprising:
- a vaporizer module comprising:
- a housing configured to removably engage a patient interface;
- a vaporizer inlet configured to detachably connect to an air delivery conduit and receive a nebula containing a nebulized liquid in a flow of air at a positive pressure with respect to ambient pressure;
- a heating element disposed in the housing and configured to generate heat to vaporize the received nebula to humidify the flow of air;
- and
- a vaporizer outlet formed as an opening in a posterior side of the housing and configured to fluidly connect to the patient interface such that, in use, the humidified flow of air exits the vaporizer module via the vaporizer outlet in a direction towards the patient interface, the heating element being disposed upstream of the vaporizer outlet;
- the patient interface being configured to receive the humidified flow of air from the vaporizer outlet and deliver the humidified flow of air to an airway of the patient,
- wherein the patient interface includes one or more surfaces around an opening in the patient interface, the housing being directly connectable to the patient interface without an intermediate tubular conduit such that the one or more surfaces of the patient interface are configured to structurally support and hold the vaporizer module in position on the patient interface.
