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.
1. A method, comprising: initiating pumping of at least one dose using, at least in part, a shape memory element, wherein the shape memory element is operatively coupled to a piston and is configured to move the piston between a plurality of positions within a first portion of the pumping mechanism
1. A method, comprising: initiating pumping of at least one dose using, at least in part, a shape memory element, wherein the shape memory element is operatively coupled to a piston and is configured to move the piston between a plurality of positions within a first portion of the pumping mechanism when pumping the at least one dose;measuring the at least one dose by monitoring the time it takes the at least one dose to pass from a first sensor to a second sensor, wherein measuring the at least one dose includes determining a flow characteristic of the at least one dose;comparing the measured at least one dose to an expected value of the at least one dose;calculating a ratio based on the comparing the measured at least one dose to the expected value of the at least one dose;applying the calculated ratio to at least one subsequent dose when delivering the at least one subsequent dose; andadjusting a flow rate of the at least one subsequent dose when delivering the subsequent dose based at least in part on the determined flow characteristic. 2. The method of claim 1, further comprising modifying a frequency of dosage delivery based on comparing the measured at least one dose to the expected value of the at least one dose. 3. The method of claim 1, wherein the at least one dose is an insulin dose. 4. The method of claim 1, including modifying the pumping of the at least one dose based at least in part on the comparing the measured at least one dose to the expected value of the at least one dose. 5. The method of claim 1, wherein measuring the at least one dose further comprises determining a flow rate of the at least one dose. 6. The method of claim 5, wherein the flow characteristic of the at least one dose corresponds to a voltage of a reaction rate associated with a component of a liquid of the at least one dose. 7. The method of claim 1, including providing one or more feedback control signals to a control unit based, at least in part, on the measured at least one dose. 8. The method of claim 7, wherein the one or more feedback control signals includes a measured volume of the at least one dose, or a measured time duration of the at least one dose. 9. An apparatus, comprising: a data communication interface;one or more processors operatively coupled to the data communication interface; anda memory storing instructions which, when executed by the one or more processors, causes the one or more processors to initiate pumping of at least one dose using, at least in part, a shape memory element, wherein the shape memory element is operatively coupled to a piston and is configured to move the piston between a plurality of positions within a first portion of the pumping mechanism when pumping the at least one dose, measure the at least one dose by monitoring the time it takes the at least one dose to pass from a first sensor to a second sensor, wherein measuring the at least one dose includes determining a flow characteristic of the at least one dose, compare the measured at least one dose to an expected value of the at least one dose, calculate a ratio based on the comparing the measured at least one dose to the expected value of the at least one dose, apply the calculated ratio to at least one subsequent dose when delivering the at least one subsequent dose, and adjust a flow rate of the at least one subsequent dose when delivering the subsequent dose based at least in part on the determined flow characteristic. 10. The apparatus of claim 9, wherein the at least one dose is an insulin dose. 11. The apparatus of claim 9, wherein the memory storing instructions which, when executed by the one or more processors, further causes the one or more processors to modify the pumping of the at least one dose based at least in part on the comparing the measured at least one dose to the expected value of the at least one dose. 12. The apparatus of claim 9, wherein the memory storing instructions which, when executed by the one or more processors, further causes the one or more processors to provide one or more feedback control signals to a control unit based, at least in part, on the measured at least one dose. 13. The apparatus of claim 12, wherein the one or more feedback control signals includes a measured volume of the at least one dose, or a measured time duration of the at least one dose. 14. The apparatus of claim 9, wherein the memory storing instructions which, when executed by the one or more processors, further causes the one or more processors to modify a frequency of dosage delivery based on comparing the measured at least one dose to the expected value of the at least one dose. 15. The apparatus of claim 14, wherein the measurement of the at least one dose further comprises a determination of a flow rate of the at least one dose. 16. The apparatus of claim 15, wherein the flow characteristic of the at least one dose corresponds to a voltage of a reaction rate associated with a component of a liquid of the at least one dose.
