Abstract: A technical solution for monitoring operation of a medical delivery device such as an infusion pump for occlusion is provided that employs sensing pump motor current and monitoring motor current with respect to at least one of a dispense stroke and an aspirate stroke in a pump cycle. The solution can be implemented alone or in combination with other occlusion sensing methods that use one or more of pump measurement data such as pump stroke duration (e.g., duration of aspirate stroke or dispense stroke in a rotational metering-type pump or a reciprocating-type pump), end-stop or limit switch activation, and duration difference between aspirate and dispense strokes to detect occlusion.
