AI Technical Summary

Technical Problem

Existing blood oscillation processing equipment cannot accurately determine the optimal critical stopping point of oscillation, resulting in insufficient oscillation leading to uneven mixing or excessive oscillation causing mechanical hemolysis. Furthermore, it cannot non-invasively obtain the true fluid state inside the sealed blood bag.

Method used

The oscillation tray, clamping mechanism, image acquisition unit, and edge data processing controller, driven by a multi-axis servo driver, collect multi-dimensional physical features of the blood bag surface, use a fluid dynamics proxy model to inversely infer the internal state of the blood bag, and adjust the oscillation parameters in real time to achieve adaptive oscillation.

Benefits of technology

It enables real-time, non-invasive sensing of the blood state inside sealed blood bags, ensuring uniform mixing while avoiding mechanical hemolysis, thus improving the safety and efficiency of blood product shaking treatment.

Abstract

This application discloses an adaptive oscillation method, system, and storage medium for blood products. The method includes: S1: acquiring and reconstructing multidimensional physical features of the blood bag surface to obtain three-dimensional morphological data and heat distribution data of the blood bag surface; S2: based on the three-dimensional morphological data and heat distribution data, using a fluid dynamics proxy model to inversely deduce the fluid shear stress and comprehensive physical suspension feature vector of the blood inside the blood bag, and performing cross-calibration on both, continuously outputting a mixed completion confidence score; S3: adjusting the motion parameters of the oscillation tray and clamping mechanism in real time according to the mixed completion confidence score, and stopping oscillation when the mixed completion confidence score continuously exceeds a preset threshold. This application achieves real-time, non-invasive sensing of the blood state inside a sealed blood bag, ensuring uniform suspension of red blood cells while avoiding mechanical hemolysis, significantly improving the safety, adaptability, and processing efficiency of blood product oscillation processing.
