This invention relates to the field of signal processing technology, providing a method, device, and storage medium for physiological state analysis based on skin sweat glands and electromagnetic waves. The method includes: simultaneously acquiring electrical signals from a user's skin sweat glands and conductive signals from electromagnetic waves; extracting features from both the skin sweat gland electrical signals and the electromagnetic wave conductive signals; inputting the extracted features into a pre-trained time synchronization and causal correlation model, establishing a dynamic mapping relationship between the skin sweat gland electrical signal features and the electromagnetic wave conductive signal features within the time synchronization and causal correlation model, and performing feature fusion based on this dynamic mapping relationship; and generating a classification result of the user's physiological state based on the output of the time synchronization and causal correlation model. By using a time synchronization and causal correlation model for skin sweat gland electrical signals and electromagnetic wave conductive signals to collaboratively analyze the two signals, the aim is to improve the accuracy and robustness of physiological state monitoring.

Peripheral nerve field stimulation (PNFS) may be controlled based on detected physiological effects of the PNFS, which may be an efferent response to the PNFS. In some examples, a closed-loop therapy system may include a sensing module that senses a physiological parameter of the patient, which may be indicative of the patient's response to the PNFS. Based on a signal generated by the sensing module, the PNFS may be activated, deactivated or modified. Example physiological parameters of the patient include heart rate, respiratory rate, electrodermal activity, muscle activity, blood flow rate, sweat gland activity, pilomotor reflex, or thermal activity of the patient's body. In some examples, a patient pain state may be detected based on a signal generated by the sensing module, and therapy may be controlled based on the detection of the pain state.

This invention discloses a method for planning minimally invasive axillary treatment based on thermal imaging, belonging to the field of medical image processing technology. The method includes: acquiring and preprocessing infrared thermal imaging data of the patient's axillary region to generate a thermal imaging sequence; calculating the temperature change amplitude, temperature rise rate, and local temperature gradient of each pixel based on the thermal imaging sequence to generate a set of sweat gland activity features; inputting the sweat gland activity feature set into a pre-established sweat gland activity prediction model to obtain the sweat gland activity distribution results within a future preset time window; using the sweat gland activity distribution results as the optimization target, and combining axillary risk tissue constraints, optimizing the path position, insertion angle, and depth of action of the minimally invasive needle path to generate the optimal minimally invasive needle path. This invention improves the positioning accuracy and treatment consistency of minimally invasive axillary treatment by constructing a sweat gland activity prediction mechanism based on thermal imaging sequences and linking it with minimally invasive needle path constraint optimization.
