Publication number: 20240017006Abstract: Devices and methods detect and mitigate pre-occlusion leak pressures within a dispense stroke of an infusion device. An infusion pump obtains pump measurements indicative of pressure, and controls its pump mechanism to pause when the pump measurements satisfy a pre-occlusion pressure threshold. Additional pump measurements are obtained during the pause and pressure-related conditions can abate during the pause. The dispense stroke is resumed by the infusion pump when the pump measurements no longer satisfy pre-occlusion pressure criteria, and can be paused again. The number and frequency of pauses, analysis of pump measurements, and resumption of a dispense stroke can be predetermined, or dynamically determined. Pauses can also be preset regardless of current pressure conditions. Pausing the pump to increase the samples or sampling rate of a measured parameter indicative of pressure (e.g., pump motor current) provides a much higher resolution for detecting an occlusion.Type: ApplicationFiled: December 9, 2021Publication date: January 18, 2024Applicant: Becton, Dickinson and CompanyInventors: Scott STEWART, Scott COREY, Kun LI
