Abstract:
A portable suction pump for life-saving purposes and normally driven by compressed gas. The pump includes a pump assembly having a suction chamber with an outlet leading to the ambient atmosphere and an inlet communicating with a secretion-receiving reservoir with attached tubing permitting suction of secretion, primarily from the air ducts of an unconscious patient. The pump is characterized by the pump assembly having a housing enclosing the suction chamber and closed at one end by a first annular diaphragm and, centrally sealingly attached thereto, a rigid body guided for movement relative to the housing and having wall portions defining, together with part of the housing, a motor chamber delimited from the suction chamber by a second annular diaphragm. The motor chamber communicates with a driving gas supply and exhaust connections and a valve arrangement for the intake and exhaust of compressed driving gas.
