Abstract
Respiratory apparatus comprising a member forming first, second and third connected gas flow passages. A patient device is connected to the third passage for conducting gas flow to and from a patient. First and second gas flow tubes are connected to the first and second passages for conducting gas to and from the third passage and the patient. A nebulizer is attached to the center of the member for feeding aerosolized medicine into the passages of the member and the tubes, for inspiration by the patient. Further, filters are mounted in both of the flow tubes for filtering makeup air and expired gas, the filters futher serving to control the gas flow through the tubes. The filters may have the same weight (and therefore the same air flow resistance), or the filter of one of the tubes may have less weight than the filter of the other tube.
