Title: Automatic respiration apparatus
IPC: A61M16/00
Filed: 1960-07-21
Abstract: 926,024. Respiratory appliances. MEOPTA NARODNI PODNIK. July 21, 1960 [July 23, 1959], No. 25392/60. Class 81 (2). In a forced breathing apparatus the changeover from exhalation to inhalation and vice versa is effected either alternately by the pressure of the gas supply and by an induced section or by the pressure alone. The equipment is shown diagrammatically in Fig. 3. Air or oxygen, under pressure, from tube 1 passes through valve 2 to a pipe 10 leading to the patient's face-mask, causing inhalation. During this period, air in a bellows 15 is withdrawn through a valve 3 and outlet 11, by applied suction, so that the bellows collapses. This causes a rod 13 and abutment 16 to move towards the left, so compressing a spring 18, until a contact plate 17 engages a bell-crank 19 which raises a stop 21 to allow a frame 22 to be moved quickly to the left by the spring 18. Thereupon, a stop 25 closes valve 2 and opens valve 4, stop 23 closes valve 3 and stop 24 opens valve 5, with the result that the applied suction, in tube 11, withdraws air through valve 5 from the patient's lungs by way of tube 10<SP>1</SP>. At the same time, gas under pressure through tube 1 and valve 4, inflates the bellows 12. The rod 13 is consequently moved to the right until a second bellcrank is actuated by the abutment 16 and the frame 22 moves over to effect changeover of the valves and a return to the inhalation phase. Flow control valves in the ducts 6, 7, 8, 9 may be adjusted to determine the rate of operation and volume of respiration.
