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.

A dual-purpose catheter comprising a valve mechanism including a first end which is adapted to be coupled to a patient and a second end which is adapted to be coupled to a source of oxygen and a source of suction, a suction tube and an oxygen tube extending from said second end of said valve mechanism and adapted to be connected to a source of suction and a source of oxygen, respectively, a unitary two-part tube assembly including a first flexible tube and a second flexible tube coupled to the patient end of said valve mechanism, said first and second flexible tubes having patient ends remote from said valve mechanism, said first and second tubes having flat wall portions along which said first and second tubes are secured together at the patient ends thereof, said wall portions of said first and second tubes facing each other and being parallel to each other, said wall portions having first and second ends which are left and right ends, said left ends facing each other and said right ends facing each other, means securing portions of said wall portions together but not securing together said wall portions at their facing left ends and right ends so that a space is present between the facing left ends and the facing right ends of said wall portions, the ends of said wall portions and the spaces between them forming generally U-shaped grooves, said means comprising a thickening of said wall portions, said thickening being integral with said wall portions, the ends of said wall portions and the spaces between the facing left and right ends thereof being able to engage and dislodge mucus which is present in the oral and tracheal passages of a patient when said unitary tube assembly is inserted into a patient, and operating means in said valve mechanism for coupling together either said suction tube and one of said flexible tubes or said oxygen tube and the other flexible tube.
