Abstract
A mechanical ventilator may include an oscillating flow controller and a respiratory interface fluidly connected to a bi-directional fluid port of the oscillating flow controller. The mechanical ventilator may be connected to a source of pressurized breathing air. Breathing air from the source of pressurized breathing air may drive the oscillating flow controller to periodically change state according to a predetermined cycle emulating a predetermined breathing pattern. The same breathing air may be provided to a user according to the predetermined cycle.
Claims16
A mechanical ventilator comprising:
- an oscillating flow controller comprising a supply port, a first bi-directional port, and an exhaust port, wherein the oscillating flow controller is configured to receive pressurized breathing air through the supply port, selectively output the pressurized breathing air through the first bi-directional port, selectively receive the pressurized breathing air through the first-bi-directional port, and selectively output the pressurized breathing air though the exhaust port;
- and
- a first respiratory interface having a first breathing air conduit, a first end of the first breathing air conduit fluidly coupled to the first bi-directional port and a second end of the first breathing air conduit configured to supply the breathing air from the first bi-directional port to a respiratory system of a first user,
- wherein the oscillating flow controller further is configured to alternate between a first state in which the oscillating flow controller enables flow of the pressurized breathing air from the supply port through the first bi-directional port to the first breathing air conduit and disables flow of the pressurized breathing air from the supply port and the first bi-directional port to the exhaust port, and a second state in which the oscillating flow controller enables flow of the pressurized breathing air from the first breathing air conduit through the first bi-directional port to the exhaust port and disables flow of the pressurized breathing air from the supply port to the first bi-directional port and the exhaust port, and
- wherein the oscillating flow controller further is configured to cyclically change state between the first state and the second state in response to the pressurized breathing air flowing therethrough.
