Abstract
The invention relates to a device for performing artificial respiration on a patient, comprising a container (1) which defines an inner volume relative to the ambient and has a first opening accommodating a valve arrangement (2, 14) which allows inflow of air or gases from the outer area to the inner area, and a second opening in connection with which there is provided a valve arrangement (3, 16) which allows outflow from the container and prevents inflow to the container through the second opening. An expansible means (7) is provided in the container and adapted to expand upon action from the outer area to displace air and/or other gases in the container (1) out through the second opening. This improves the certainty that oxygen and/or other gas finds its way to the patient's air passages.
