ABSTRACT:
A dual purpose catheter valve especially for oxygen insufflation and mucous suction from the lungs and trachea system of a patient, is provided. The body has two snap-fitted generally cylindrical parts, mounted for relative rotation, with an oxygen port, suction port and catheter port on the outer body part for connection to the respective valves, and ports formed in the wall of the inner body part. There are two pairs of inner body ports, one pair for alignment with the oxygen port and the catheter port of the outer body part, the other pair for alignment with the suction port and the catheter port of the outer body part. When one of the oxygen or suction ports is aligned for fluid communication to the interior of the body and to the catheter port, the other of the oxygen or suction ports is shut off by a wall portion of the inner body part. There is a neutral position of the two body parts when rotated relative to each other, where neither the oxygen nor suction ports communicates to the catheter, so that there may be a settling of the system when switched from insufflation to aspiration, or vice versa, and so that the change from one to the other is not abrupt, thereby reducing the risk of trauma to the patient. The oxygen and suction ports do communicate with each other in this neutral position.
