Abstract

The invention relates to a lung ventilator which includes a breathing-gas chamber or breathing-gas bag (3) having flexible walls and a variable volume which is enclosed in a rigid driving-gas chamber (4). The breathing-gas chambers connected to a source (6) of breathing gas, and receives and collects the gas and then supplies it to the airways of a patient through an inspiration line (9) and a hose (10). A driving-gas chamber (4) is connected to an arrangement (13-15) for supplying air to the driving-gas chamber (4) so that the breathing gas chamber is compressed and breathing-gas is fed through the inspiration line and the hose to the airways of the patient in the form of a breath. The infeed or air into the driving-gas chamber (4) is controlled by a central control unit (8) which generates a control signal for an electrically controlled regulating means (15) which is arranged to control the infeed of air into the driving-gas chamber (4), and thus the pressure created therein and in the airways of the patient, in response to the applied control signal. <IMAGE>
