Flow rate compensation in infusion pump system
A newly granted patent (Publication Number: US11992651B2) describes an infusion pump system designed to optimize the flow rate accuracy of multiple infusion pumps in a stack configuration. The system includes a mounting device, a fluid supply container, and multiple infusion pumps connected in a specific order. These infusion pumps are capable of determining their location in the stack, identifying a reference infusion pump based on its distance from the fluid supply container, and adjusting the flow rate of the non-reference pumps based on their distance from the reference pump.
The patent details the method by which the infusion pumps determine their location in the stack by measuring head height pressure and ordering themselves accordingly. The reference infusion pump is identified based on its proximity to the target fluid pressure, ensuring optimal flow rate accuracy within a specified range. Additionally, the system allows for the addition of more infusion pumps to the stack, with each pump determining its position and adjusting its flow rate based on the distance from the reference pump. The communication between the infusion pumps is facilitated through various methods such as Bluetooth®, Wi-Fi, NFC, serial connection, or controller area network connection, enabling seamless coordination and adjustment of flow rates within the system.
