ABSTRACT:
A portable artificial respiration device of lightweight construction for use in operations and for resuscitation. A housing includes an inlet for receiving a respirator fluid under pressure, a conduit for communicating with a patients respiratory system and an outlet for communication with the atmosphere. A rotatable distributor valve within the housing comprises a tubular member having an opening at one end which continuously communicates with the conduit. An opening in the wall of the tubular member when rotated to be adjacent the inlet provides a path for the respirator fluid to the patient for inspiration and when positioned adjacent the outlet provides an expiration path from the patient to the atmosphere. A variable speed drive under electronic speed control rotates the member to determine the inspiration and expiration rate of the patient when coupled to the device.
