Abstract:
In a system including a compartment and a person in contact with the compartment having an interior, an artificial respiration system comprising:a device for moving fluid, the device including a fluid exit port and a fluid entrance port;a first housing defining a first hole in communication with the exit port, a second hole in communication with the interior of the compartment, a third hole in communication with the entrance port, and a fourth hole;a second housing in the first housing, the second housing defining a first chamber with a first hole, and a second hole, and a second chamber with a third hole, and a fourth hole;a driver mechanically coupled to the second housing, to vary the angular displacement of the second housing relative to the first housing;a user interface for generating a first signal indicating a first pressure, a second signal indicating a second pressure, and a third signal indicating a period; anda controller that generates a driver control signal, the driver being responsive to the driver control signal, the controller generating the driver control signal to cause the driver to effect a first angular displacement of the second housing depending on the first signal, and to effect a second angular displacement of the second housing depending on the second signal, wherein the second hole of the first housing is substantially perpendicular to the first hole of the first housing, and the fourth hole of the first housing is substantially perpendicular to the third hole of the first housing.
