  • Rapid response occlusion detector for a medication infusion pump
    Patent number: 5647853
    Abstract: An improved occlusion detector is provided in a medication infusion pump to monitor medication delivery to a patient, and to provide an early alarm in the event of medication nondelivery. The detector comprises a force sensor and related control circuit for reading and comparing the pressure applied to the medication at the time of pump operation to administer a dose to the patient, with the same pressure at a later point in time preceding the next dose. If the difference between the pressure readings is less than a predetermined value, an occlusion of the medication delivery line is indicated and an alarm is activated.
