Apparatus and method for ventilation and aspiration
First Claim
1. In combination, for use in patient ventilation and aspiration circuits:
- a manifold assembly, having a body with a distal end portion, a proximal end portion and an open interior;
said distal end portion of said body being adapted to couple with an intubation device,said proximal end portion of said body being formed as an open port defined by a continuous wall, said proximal end portion further being approximately axially aligned with said distal end portion so that a catheter may be inserted through said proximal end portion to exit from said distal end portion;
structural means for associating a catheter with said proximal end; and
a catheter assembly comprising;
a flexible tracheal suctioning catheter tube attached at a first end to a proximal coupling and at a second end opposite said first end to a distal coupling,said proximal coupling being structurally adapted releasably to connect to first connecting structure associated with a vacuum valve, andsaid distal coupling being structurally adapted releasably to connect to second connecting structure associated with said manifold assembly;
said vacuum valve comprising;
a flow channel defined by a continuous flexible wall; and
associated actuation structure being arranged for selective positive, finger-actuated, adjustment between a first position and a second position, said actuation structure being constructed and arranged such that in said first position said actuation structure presses said flexible wall to occlude said flow channel and in said second position said actuation structure releases said flexible wall to open said flow channel;
a collapsible bag formed of stretchable material enveloping said suctioning catheter tube and attached at opposite ends to said proximal and distal couplings; and
a lanyard element connected in parallel with said bag between said proximal and distal couplings, said lanyard limiting the axial separation of said couplings, said lanyard being adhered directly to a wall forming said bag.

Abstract
A sealed ventilation circuit interface system, which enables simultaneous patient ventilation and safe tracheal suctioning, is structured to accommodate any of a wide variety of commercially available suction catheters. The interface system comprises a manifold assembly, and an adaptor. The manifold assembly may be attached to a patient for an extended period, while the adaptor is advantageously constructed as a single procedural use disposable device. The adaptor couples with the manifold assembly, and may be configured to effect the introduction of a catheter through a normally closed valve structure carried by the manifold assembly. The adaptor may alternatively be configured to interface the manifold with a bronchoscope or other appliance. A vacuum valve assembly biased in an open position is selectively actuated between open and closed positions and can be locked in a closed position. The vacuum valve remains at either position without ongoing manual pressure.
