AI Technical Summary
Existing dialysis priming sensors are inaccurate due to fluctuations in ambient light, tube properties, and fluid type, leading to errors in detecting when a tube is properly primed for medical fluid delivery.
A dialysis priming sensor with three light emitters and a detector that activates in a sweeping pattern, creating unique waveforms for each tube state, allowing for accurate detection by comparing these waveforms to reference curves, thereby reducing variability from ambient light, tube, and fluid properties.
The sensor provides reliable detection of fluid presence in dialysis tubes, minimizing errors and ensuring proper priming without calibration for different ambient conditions, tube properties, and fluid types, applicable to various medical fluid delivery systems.
