Infusion devices with distributed motor control and related operating methods

This invention describes a medical infusion device, like a pump, that delivers fluid to a patient using a motor. The key feature is how the motor is controlled: it uses two separate electronic control modules that communicate with each other through a specific back-and-forth "handshaking" sequence. One module requests fluid delivery and enables the power supply, but only after the second module acknowledges the request. The second module then operates the motor based on the dosage command, ensuring both modules agree before any fluid is delivered.
