Abstract:
1. A manifold for connection to a medical/surgical waste collection unit, the waste collection unit having a receiver for receiving the manifold, said manifold comprising: a housing having: opposed spaced apart distal and proximal ends; a void space between the ends, the void space being at least partially defined by an inner face adjacent the distal end, the inner face having at least one inlet port into the void space adjacent the distal end of the housing; a rib that extends outwardly from the inner face and that extends circumferentially around the inlet port; and an outlet opening from the void space in the proximal end; at least one fitting attached to the housing that extends away from the housing, the fitting dimensioned to receive a suction line and opening into the at least one housing inlet port; and a backflow prevention valve disposed in said housing, said backflow prevention valve including: a hub that is statically mounted to said housing void space-defining inner face so as to be spaced from the at least one inlet port and said rib that extends around said inlet port; a valve member, said valve member positioned and dimensioned to extend over the at least one inlet port and said rib that surrounds the inlet port; and a hinge that extends from said hub to said valve member that pivotally connects said valve member to said hub so that said valve member can pivot between a closed position in which said valve member is rotated away from both said rib and the inlet port to allow fluid flow from said fitting and the inlet port into the housing void space.
