Valve for resuscitator apparatus

摘要

This disclosure relates to a valve for a resuscitator apparatus including a resuscitator bag and a reservoir bag. The valve is mounted in a coupling between the two bags. The valve comprises a reed flapper in a housing, the reed flapper having one side exposed to the interior pressure and another side exposed to the ambient pressure. The reed flapper is movable in response to a higher interior or ambient pressure (a pressure differential), to open a housing port to allow flow out of or in to the reservoir bag interior. The valve further includes a biasing part to increase the opening pressure differential in one direction or the other.
