Reusable intake valve for a resuscitation bag, comprising an inner part, an outer part, and a valve housing. The inner and outer parts are separate parts designed to be connected at an opening in the bag and to seal an edge of the opening between them. The inner part includes a first valve member designed to admit air into the bag and close for air flow in the opposite direction. The valve housing includes second and third valve members with the second valve member capable of admitting ambient air into the valve housing and close for air flow in the opposite direction. The third valve member is capable of releasing air from the valve housing to the surroundings when opened and close for air flow in the opposite direction. The valve housing includes a first pipe member for connection to an oxygen reservoir and a second pipe member for connection to an oxygen source. In this reusable intake valve, the outer part and the valve housing are integrated into one piece. |
