Bayer has patented a fluid injector system that employs a flow rate algorithm to monitor and adjust fluid delivery. The system calculates actual flow rates based on pressure changes, identifies deviations from programmed rates, and compensates for these discrepancies in subsequent delivery intervals during medical procedures.

The patent US12070577B2 describes a fluid injector system designed for administering fluids to patients with enhanced accuracy and adaptability. The system includes a memory component that stores a programmed flow rate and a maximum allowable deviation for fluid delivery. It features at least one sensor to measure the pressure of the fluid, which is generated by a drive component during the delivery process. A control device, equipped with a processor, is responsible for determining the actual flow rate based on pressure changes over specified time intervals, calculating deviations from the programmed flow rate, and adjusting the flow rate for subsequent intervals accordingly. This iterative process aims to maintain precise fluid delivery throughout the procedure.

Additionally, the system incorporates a mechanism for flow rate correction, which compares the actual flow rate deviation to the maximum allowable deviation. If the deviation exceeds this threshold, the correction is set to the maximum allowable deviation. The system can also utilize machine learning models to optimize fluid delivery based on real-time data. The method outlined in the patent emphasizes continuous monitoring and adjustment of the flow rate, ensuring that the fluid is delivered at the newly programmed rate in subsequent intervals. This innovative approach aims to enhance the reliability and effectiveness of fluid administration in medical settings.
