Abstract
High pressure oxygen is released through a side of an open-ended ventilating bronchoscope or laryngoscope into its lumen in a direction toward a distal end. The oxygen draws air through the proximal end. Medical gasses and vapors are drawn through an entrainment arm at the side of a ventilating endoscope by oxygen which is released near the distal point of confluence of the entrainment arm and the scope lumen.
Claims10
Ventilating endoscope apparatus comprising an elongated endoscope having a length greater than a width, having a continuously open proximal end and a continuously open distal end, and an elongated wall means for laterally enclosing the scope between the open ends, thereby defining a lumen continuously open at opposite ends, fluid inlet means connected to and opening at a small angle along the wall means near the proximal end and fluid pressure means connected to the inlet means and the inlet means opening into the lumen in a direction toward the distal end for passing fluid from the inlet means into the lumen toward the distal end and entraining air through the proximal end into the lumen.
