The present invention relates in one aspect to an intravenous fluid delivery system which comprises a power supply and an infusion fluid warmer that comprise respective data communication interfaces supporting data exchange through a power supply wire connected between the power supply and the infusion fluid warmer.

The present invention relates in one aspect to a power supply for intravenous fluid delivery systems and an infusion fluid warmer for the intravenous fluid delivery systems. The power supply comprises a rechargeable energy storage component for delivery of a primary DC voltage. The power supply comprises a voltage regulator configured to deliver a secondary DC voltage which may exhibit a lower maximum current output than a maximum current output of the primary DC voltage.

The present application relates to the technical field of medical Internet of Things, and in particular to a self-adaptive infusion collaborative control method and system based on intelligent decision-making. The method comprises: an end device analyzes multi-modal physiological time series data and infusion parameters through an end-to-end patient state evaluation model integrated in a sub-body infusion unit, and outputs a patient state index and infusion suggestions; combined with a pipeline pressure signal, an adaptive flow rate control algorithm based on LSTM is used to generate motor control instructions to realize closed-loop control. The edge device periodically aggregates local model parameter updates of multiple end devices through a mother base station. The cloud device fuses all updates uploaded by the edge devices based on a federated averaging algorithm, generates an optimized global model, and issues the global model. The present application realizes a paradigm shift from isolated execution to collaborative perception-decision-evolution of infusion, drives continuous evolution of group intelligence under the premise of protecting data privacy, and improves the accuracy, safety and overall intelligent level of infusion therapy in complex environments.

The invention provides an IV system for monitoring a patient that is positioned on the patient's body. The IV system includes: 1) a catheter that inserts into the patient's venous system; 2) a pressure sensor connected to the catheter that measures physiological signals indicating a pressure in the patient's venous system; 3) a motion sensor that measures motion signals; and 4) a processing system that: i) receives the physiological signals from the pressure sensor; ii) receives the motion signals from the motion sensor; iii) processes the motion signals by comparing them to a pre-determined threshold value to determine when the patient has a relatively low degree of motion; and iv) process the physiological signals to determine a physiological parameter when the processing system determines that the motion signals are below the pre-determined threshold value.
