Abstract
A connector valve assembly for admission of catheters through endotracheal tubes employs a connector body having a tracheal tube port, a respiratory tube port and an end portion adapted for insertion of a catheter through the body and through the tracheal tube for patient airway suctioning. An end cap on the end portion has an aperture with a ring seal for sealably engaging the catheter as it is inserted therethrough and has a check valve disposed inwardly of the ring seal toward the respiratory and tracheal tube ports. The end cap defines an air lock chamber for insertion of the catheter through the connector body without interrupting positive pressure ventilation of the patient.
