Abstract
A ventilating and aspirating apparatus for delivering respiratory gases to the trachea of a patient and aspirating congested lungs and breathing passageways includes a flexible catheter tube extendable into and withdrawable from the patient's trachea, a resilient pliable sheath lending a structural rigidity to the apparatus and receiving the catheter tube when withdrawn from the patient, a valve structure attached to the catheter tube which is slidable along the length of the sheath, a manifold structure and swivel mounting means to allow coaxial swivel motion of the components, and a collapsible/extendable sealing envelope structure arranged to cover components on the proximal side of the manifold.
Claims38
A ventilating and aspirating apparatus for delivering respiratory gases to the trachea of a patient and aspirating congested lungs and breathing passageways comprising:
- a flexible catheter tube having a catheter lumen and a longitudinal catheter axis, said catheter tube being extendable into and withdrawable from a patient's trachea and having a distal end structured to permit secretions to enter said catheter lumen;
- a vacuum valve with an inlet connected to the lumen of said catheter tube, an outlet constituting means for connection to a vacuum source, and an actuator for selectively communicating the lumen of said catheter tube with the vacuum source;
- a resilient, pliable sheath having a longitudinal sheath axis, said sheath receiving and coaxially surrounding said catheter tube and having an open distal end through which said catheter tube is slidable;
- a manifold connected to the distal end of said sheath and having a center passage in open communication with the interior of said sheath, said manifold including means for establishing a fluid connection between said center passage and a patient ventilation and exhalation apparatus and being structured to permit slidable passage of said catheter tube through said center passage;
- and
- an "O"-ring disposed within said manifold, said "O"-ring fitting coaxially over said catheter tube thereby isolating the distal portion of said catheter tube extending beyond said "O"-ring.
