Abstract
A medication infusion device comprises a retainer for holding a medication-containing receptacle of the type which is actuatable to expel the contents of medication therefrom. A sensor is included for sensing a characteristic related to the amount of medication within the receptacle.

A control mechanism, associated with the sensor and the timing device, actuates the receptacle to expel its contents at a controlled rate over the selected period of time.
