  • Patent number: 4244365
    Abstract: An overpressure device is disclosed for use in a liquid infusion set for the purpose of detecting excessive pressures which may occur during infusion. The device comprises a tubular member with an inlet and an outlet, a closed pressure chamber and a bridging portion containing a small bore passage which connects the pressure chamber with the tubular member. In a preferred form, the interconnecting passage takes a tortuous path. An optical sensor positioned on the pressure chamber will detect the presence of liquid at a predetermined position in the chamber, when the liquid rises as a result of excessive pressure in the set, and respond by stopping the flow of liquid in the set.
