ABSTRACT:
An apparatus for determining whether an IV infusion set has infiltrated the tissue of a patient includes a pump for pumping fluid through the IV set into the patient and a pressure transducer operably engaged with the IV set between the pump and patient. The pressure transducer is electrically connected to a microprocessor, and the microprocessor is electrically connected to the motor of the pump to control the pump to alternately withdraw from and infuse into the patient a predetermined volume of fluid.
This predetermined volume of fluid is withdrawn from the patient by the pump at a preselected withdrawal pressure, while the pump infuses the predetermined volume of fluid into the patient at a preselected infusion pressure. The microprocessor measures both the time period for infusing the predetermined volume of fluid and the time period for withdrawing the predetermined volume of fluid. Based upon these time periods, the microprocessor evaluates whether the IV set has infiltrated the patient's tissue.
