Abstract:
1. A suction flow regulator comprising: an adapter having a distal and a proximal end and a vacuum flow path for allowing a vacuumed fluid to flow from said distal end to said proximal end; and a device fixed inside said adapter, wherein said device is configured to permit air from outside said suction flow regulator to access a chamber within said vacuum flow path according to a vacuum level, wherein said device comprises a first grommet comprising a elastomeric material and having a distal end and a proximal end corresponding to said distal and proximal ends of said adapter, and a second grommet comprising a lower durometer elastomeric material than said first grommet, wherein said second grommet is configured to deflect during an increased vacuum level.
