摘要：
A pistol grip suction device comprises a hollow body member having first leg joining second leg at elbow, the legs being generally tubular and disposed approximately 90 degrees apart； a push rod extending through push rod aperture at elbow, the push rod extending into hollow second leg, the push rod having a button on proximal end outside the body, and valve on distal end inside the body； a valve seat disposed within second leg around push rod； valve mounted on the push rod through the valve seat, the suction port having a diameter at least two times the diameter of push rod through suction port； a spring biasing push rod into extended position with respect to second leg such that valve bears against valve seat and closes suction port, wherein a force against button greater than biasing force of spring displaces valve from valve seat and opens suction port.
