Patent ID: 7878980

Claim:
A gas flow diverter in combination with a respiratory measuring device, the combination comprising: a respiratory sensor having a tube section with an inlet end and an outlet end and adapted for communicating a respiration flow through an interior passage; a number of apertures formed through the tube section near a restriction, each aperture being fluidly connected to the interior passage; and a diverter comprising: a body defining a generally blunt end and having a generally conical surface extending from the blunt end, the blunt end being engageable with the tube section of the respiratory sensor such that the conical surface extends away from the blunt end and terminates nearer the restriction and any of the apertures of the tube section than the blunt end, the entire body being longitudinally offset, in a common direction aligned with a direction of the respiration flow, from the restriction and any of the apertures such that the diverter increases turbulence of the respiration flow before the respiration flow enters the restriction to generate a pressure differential on generally opposite sides of the restriction relative to the respiration flow.
