Abstract
The invention relates to a device for performing artificial respiration on a patient, comprising a container ( ) which defines an inner volume relative to the ambient and has a first opening accommodating a valve arrangement ( ) 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 ( ) which allows outflow from the container and prevents inflow to the container through the second opening. An expansible means ( ) 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 ( ) out through the second opening. This improves the certainty that oxygen and/or other gas finds its way to the patient's air passages.
