  • Patent number: 5254110
    Abstract: A surgical aspiration system includes aspirating equipment having an inlet through which a vacuum may be drawn for collecting bodily fluids during a surgical procedure. Suction tubing is connected to the aspirating equipment inlet and extends therefrom to a patient undergoing the surgical procedure. A suction catheter is attached to a distal end of the suction tubing for positioning within a portion of the patient's upper airway. A support for the suction tubing includes a normally horizontally disposed base which is adapted to fit beneath a patient-supporting mattress, and a bracket member extending vertically upwardly from the base. An aperture is provided through the bracket member in which a portion of the suction tubing is positioned. A pair of anchor slots are provided in the bracket member adjacent to the aperture, for pinching off a portion of the distal end of the surgical tubing to essentially stop the flow of fluid through the suction tubing.
