Reusable intake valve for a resuscitator bag, comprising an inner part (31), an outer part (32) and a valve housing (39). The inner (31) and outer (32) parts are separate parts designed to be connected at an opening (6) in the bag (1) and retain the edge of the opening (6) between them. The inner part is equipped with a first valve (37) designed to admit air into the bag (1) and close for air flow in the opposite direction. The valve housing is equipped with a second and a third valve (40, 41), where the second valve (40) is designed to admit air into the valve housing (39) from the surroundings and close for air flow in the opposite direction. The third valve (41) is designed to release air from the valve housing (39) to the surroundings and close for air flow in the opposite direction. The valve housing has a pipe stub (42) for connection to an oxygen reservoir (3) and a pipe stub (44) for supply of oxygen. The outer part (32) and the valve housing (39) are integrated into one piece. <IMAGE> |
