摘要：
The object of the invention is an inspiratory gas volume divider comprising at least two inspiratory lines (18, 19) having inspiratory branches (14,16) at ends thereof and comprising one-way valves (2,3) and at least two expiratory lines (20, 21) having expiratory branches (15,17) at ends thereof and comprising one-way valves (7,12). The inspiratory branches and expiratory branches are in pairs combined with each other in at least two inspiratory- expiratory pairs. The initial portions of the inspiratory lines are connected to the divider valve (23) provided with a control input. In the inspiratory lines, after the volume valve divider, there are included systems measuring gas volume (11,12) with output signals thereof delivered to the controller (22), and the output signal thereof is connected to the volume divider's input. Further, the object of the invention is a method of dividing the inspiratory gas volume in a divider comprising at least two inspiratory lines and two expiratory lines connected to a controlled divider provided with a control input. The method comprises the stages of: setting the desired inspiratory gas volume division, measuring and subsequently re-setting the division in feedback loop via the control input. In the stage of measuring, the volume of gas in each of the inspiratory lines is subjected to measurement, and the measurement signal is converted in an automatic controller to the valve divider's control signal.L'invention concerne un diviseur de volume de gaz inspiratoire comprenant au moins deux lignes d'inspiration (18, 19) ayant des branches inspiratoires (14, 16) à leurs extrémités et comprenant des valves anti-retour (2, 3) et au moins deux lignes d'expiration (20, 21) ayant des branches d'expiration (15, 17) à leurs extrémités et comprenant des valves anti-retour (7, 12). Les branches inspiratoires et les branches expiratoires forment des paires combinées les unes aux autres en au moins deux paires inspiratoires-expiratoires. Les pa
