Abstract
A medication delivery system delivers medication to a patient. The system includes a base and a reservoir disposed about the base for storing the medication. A pump for delivering the medication to the patient is supported by the base. The pump includes a housing having an inlet and an outlet. A first pinch lever is disposed near the inlet and a second pinch lever is disposed near the outlet. Each of the pinch levers move between an open and closed position to control a flow of the medication into the housing. A motor operatively engages the pinch levers to move the pinch levers such that the medication can be delivered to the patient. A biasing device engages at least one of the pinch levers and works in conjunction with the motor to normally bias the at least one pinch lever into the closed position during delivery of the medication to the patient and to maintain the at least one pinch lever in the closed position during a failure of the motor to prevent the inadvertent delivery of the medication to the patient.
