ABSTRACT:
A respirator for emergency supply to a patient, includes a respiratory gas supply which is connected through two control valves and two regulating valves to a patient. The regulating valves are coupled together by adjusting means which permits their adjustment and one is connected in the gas supply line to the first regulating valve, and the other is connected in the connection from the second regulating valve to the patient. The inhalation and exhalation time of the patient may be adjusted. The valve controls provide a time control which includes a control of the second regulator valve by two separate respirator gas volume connections of predetermined volume amounts which act on the second control valve to shift it into one of two defined positions. The second control valve establishes a respiratory gas connection in the inhaling phase through the second regulating valve and a ventilating valve which is connected directly to the patient.
