ABSTRACT:
A pressure activated shut-off device which will prevent the flow of liquid in an intravenous administration set when the pressure in the system reaches a predetermined point. The shut-off device is utilized in an I.V. set wherein a pumping mechanism is utilized as the force for moving the liquid through a filter. The shut-off device has a biasing element which is set with a predetermined force so as to become activated and stop fluid flow so that the filter mechanism is not ruptured by excessive fluid pressure.
