Abstract

1,076,990. Breathing apparatus. O. H. DRAGER, [trading as DRAGERWERK HEINR. & BERNH. DRAGER]. March 21, 1966 [March 20, 1965], No. 12417/66. Heading AST. A respiratory apparatus as illustrated with reference to the drawing comprises a breathing bag 8, means for expanding and contracting the breathing bag (such as pressure generator 12 and housing 9), an adjustable abutment 14 arranged to limit the expansion of said breathing bag, biasing means 17 urging said abutment to contract the bag, releasable detaining means 16, 26, 27 arranged to detain said abutment in a limiting position, and a counting mechanism 18, 19, 20, 21 arranged to count changes in the pressure phase in the breathing bag and to release said detaining means (such as by operation of cam 22, microswitch 24, solenoid 25 and armature rod 26) at a negative pressure phase after a predetermined number of pressure phase changes, thereby to permit expansion of said breathing bag beyond said limit whereby the next inspiration is deep. The apparatus may be devized to control exhalation as well.
