1. A flow indicating system comprising:
- a conduit adapted to contain a substance, wherein said conduit defines a flow path along which the substance is adapted to primarily flow;
a viewing port connected to said conduit, wherein said viewing port allows visualization of an internal space defined at least in part by said viewing port; and
a flow indicator positioned within and visible through said viewing port, said flow indicator hingedly supported relative to said conduit, wherein said flow indicator is pivotable about a hinge axis in a first direction from an at rest position to an inhalation position in response to an inhalation pressure applied thereto, wherein said flow indicator is pivotable about said hinge axis in a second direction in response to an absence of the inhalation pressure being applied thereto, and wherein said second direction is opposite said first direction.

Abstract
A flow indicating system that includes a conduit that contains a substance, wherein the conduit defines a path along which the substance primarily flows and a viewing port attached to the conduit and the viewing port prevents substantially non-ambient atmosphere gases and substances from escaping therefrom and allows visualization of an internal space defined by the viewing port. A flow indicator that is positioned within the conduit so as to be viewed via the viewing port and is positioned so as to not to substantially interfere with a flow of the substance along the path.

18. A flow indicating system comprising:
-
a conduit adapted to contain a substance, wherein said conduit defines a flow path along which the substance is adapted to primarily flow; a viewing port connected to said conduit, wherein said viewing port allows visualization of an internal space defined at least in part by said viewing port; a valve disposed in said conduit; and a flow indicator positioned within and visible through said viewing port, said flow indicator hingedly connected to said valve, wherein said flow indicator is pivotable about a hinge axis in a first direction from an at rest position to an inhalation position in response to an inhalation pressure applied thereto, wherein said flow indicator is pivotable about said hinge axis in a second direction in response to an absence of the inhalation pressure being applied thereto, and wherein said second direction is opposite said first direction.

19. A flow indicating system comprising:
-
a housing defining at least in part a conduit adapted to contain a substance, wherein said conduit defines a flow path along which the substance is adapted to primarily flow; a viewing port connected to said housing, wherein said viewing port allows visualization of an internal space defined at least in part by said viewing port; and a flow indicator positioned within and visible through said viewing port, said flow indicator directly, hingedly connected to said housing, wherein said flow indicator is pivotable about a hinge axis in a first direction from an at rest position to an inhalation position in response to an inhalation pressure applied thereto, wherein said flow indicator is pivotable about said hinge axis in a second direction in response to an absence of the inhalation pressure being applied thereto, and wherein said second direction is opposite said first direction. - View Dependent Claims (20, 21)
