Precise accurate measurement of the administration of drugs using the injection method by means of ultrasonic pulse-echo principles

A dosage control module, comprising:

• a pulse transmitter that transmits a first plurality of voltage pulses to a piezoelectric transducer arranged on a medication delivery device;
• a receiver that receives, based on the first plurality of voltage pulses, a second plurality of voltage pulses from the medication delivery device;
• a time-to-digital converter that determines an amount of time between a first voltage pulse and at least one second voltage pulse of the second plurality of voltage pulses;
• and
• a control module that
• determines, based on the amount of time, at least one of i) an amount of medication administered from the medication delivery device and ii) whether air bubbles are present in the medication within the medication delivery device, and
• selectively activates at least one of a visual indication and an audio indication based on the determination.
