[0002] Pain is one of the most common clinical symptoms, and chronic pain is considered the third leading health problem after cardiovascular disease and cancer. However, with current technology, pain assessment can only rely on patients' verbal reports.
[0003] Current objective pain assessment methods mostly rely on single biological signals (such as electroencephalography), failing to adequately consider the potential impact of baseline differences. Furthermore, these methods largely focus on assessing laboratory-induced pain (such as pain induced by electrical stimulation), lacking applicability in practical clinical applications.

[0016] The beneficial technical effects of this application include a pain monitoring device that provides the coordinated acquisition of objective physiological signals and subjective pain information, thereby enabling pain monitoring.
[0017] The beneficial technical effects of this application include that the blood oxygen detection module and the electroencephalogram (EEG) detection module work together to detect blood oxygen saturation and EEG, providing basic physiological parameters for pain monitoring.
[0018] The beneficial technical effects of this application include that the pain physiological signal acquisition device may also include a blood oxygen detection module, a heart rate detection module, an electroencephalogram (EEG) detection module, and a blood pressure detection module; pain detection is based on multiple physiological parameters, making the dimensions of physiological data analysis richer, and pain monitoring more objective and closer to reality.
[0019] The beneficial technical effects of this application include that the blood oxygen detection module and heart rate detection module are more portable and easier to collect and apply in large quantities compared to other physiological parameters.
[0020] The beneficial technical effects of this application include the setting of pain start and end buttons, which synchronously initiates the acquisition or identification of physiological signals at the onset of pain and synchronously stops the acquisition or identification of physiological signals at the end of pain. This reduces the data load of the system and makes it easier to capture key information related to pain.

The standardized quantification of pain intensity information facilitates long-term pain assessment for individuals. The standardized quantification of pain intensity information also facilitates comparative studies of pain assessments across different individuals. In pain monitoring, the pain intensity feedback device transforms subjective feelings into objective signals, making the recording of the pain process more quantitative.

[0026] The beneficial technical effects of this application include that the pain intensity feedback device includes a pressure sensing module; the pressure sensing module senses different levels of force input by the user and reflects the corresponding pain intensity. Attached Figure Description
