ABSTRACT:
A dual-purpose catheter for performing suction or oxygen feed on a patient including two cylindrical bodies rotatably coupled together and held together by a spring which is biased to hold the bodies in a first position with respect to each other but permits rotation to a second position. One body includes first and second tubes which can be coupled to a source of suction or a source of oxygen, and the other body includes means for receiving said tubes in a tight fit and tube means for coupling either suction or oxygen to the patient, depending on the rotation state of the two bodies with respect to each other. The catheter bodies include solid tubes positioned to block the oxygen path to the patient when suction is operating and to block the suction path to the patient when oxygen is operating.
