Abstract
A micro fluid delivery device is particularly useful in medical applications. The device may be worn or carried by the user and may deliver drugs or other medicaments to the user or patient. The device has a control system that accepts input from the user and controls all aspects of operation of the device. The control system measures the output of the pump and adjusts the output of the pump to achieve the desired dosage rate and size. This eliminates differences from pump to pump that result from inevitable variations in the manufacturing of such small scale affordable devices.
