The suction device is for aspirating mucus from a neonate. It has an inlet tube (1) terminating within an actuating chamber (2). A collection chamber (3) is connected to the actuating chamber (2). The actuating chamber (2) and the collection chamber (3) are formed of a flexible tube (4). Within the flexible tube (4) there is a length of resilient polythene tubing (11), which normally gives the actuating chamber (2) a generally elliptical cross-sectional shape. A flutter valve (12) is secured to the outlet end of the inlet tube and extends within the tubing (11). The actuating and collection chambers (2, 3) are interconnected by a connection tube (14) connected to an outlet flutter valve (15) within the collection chamber.
