AI Technical Summary

Technical Problem

Existing treadmill control technologies for cardiac rehabilitation training are mostly based on a single heart rate or simple blood pressure threshold, which makes it difficult to characterize the cardiac load state in multiple dimensions. They also lack forward-looking safety margin control and cross-cycle adaptive adjustment, making it difficult to balance safety and efficiency in the training process.

Method used

A patient-individualized nonlinear safety manifold is constructed in the three-dimensional space of heart rate-stroke product-ST segment offset. The safety margin index is calculated by predicting the minimum geodesic distance of the load trajectory. Combined with optimized control and emergency stop mechanisms, individualized adjustment of treadmill speed and incline is achieved, and the safety boundary is updated through cross-training.

Benefits of technology

It improves the safety and efficiency of cardiac rehabilitation training, can identify hidden dangers in advance, optimize exercise prescriptions, reduce the workload of doctors in frequently adjusting parameters, and improve the accuracy of individualization and automation.

Abstract

The present application relates to a kind of medical treadmill control method and system for cardiac rehabilitation training.The method is based on cardiopulmonary exercise test results, constructs patient individualized nonlinear safety manifold;Signal is collected during training, forming three-dimensional cardiac load vector, linear prediction is carried out in sliding time window to obtain future load trajectory, and its minimum distance to the outer boundary of safety manifold is calculated and normalized as safety margin index;Under the constraint that safety margin index is not lower than threshold value and speed, slope change rate is limited, the speed and slope adjustment amount of treadmill are optimized and solved, and staged deceleration emergency stop is triggered when safety margin enters dangerous area or abnormality is detected;And anisotropic scaling update is performed on safety manifold.The method and system can prospectively identify multidimensional cardiac load risk, improve effective training time and individualization level of exercise prescription under the premise of safety.
