Abstract
Description
Technical Field
[0001] This invention relates to the field of wristband technology, specifically a pain level assessment wristband with positioning function. Background Technology
[0002] Pain, as the fifth vital sign, is crucial for accurate assessment in disease diagnosis, treatment evaluation, and improving patients' quality of life. Currently, widely used clinical pain assessment tools, such as the Visual Analogue Scale (VAS), Numerical Rating Scale (NRS), and Faces Perception Scale (FPS-R), heavily rely on patients' subjective descriptions and cognitive cooperation. These methods have significant limitations: they are difficult to implement for children, the elderly, patients with communication difficulties, or those with impaired consciousness; and the assessment results are easily influenced by factors such as the patient's psychological state and education level, leading to poor reliability and inconsistent data. Furthermore, traditional electronic pain recording devices only digitize the aforementioned subjective rating methods, failing to address the objectivity of pain assessment and unable to correlate pain attacks with the patient's specific environment and location, making it difficult to trace and manage pain triggers.
[0003] Therefore, the specific technical problem of the present invention is to provide an objective pain assessment method that does not rely on the patient's subjective description, which is especially suitable for special populations such as children and the elderly, and to realize the intelligent association between pain data and geographical location information, thereby improving the objectivity and continuity of pain assessment.
[0004] Therefore, there is an urgent need to develop a pain level assessment wristband with positioning function to solve the problems in the existing technology. Summary of the Invention

The pain assessment algorithm includes the following steps: S1: Baseline calibration and peak detection are performed on the skin conductance response signal; S2: Extract heart rate variability features from blood flow signals; S3: Normalize the signal by combining it with body temperature; S4: Outputs pain levels through a weighted fusion model, categorized into four levels: no pain, mild, moderate, and severe.
