Pain quantitative analysis system and method based on human body physiological signal multi-parameter fusion

Abstract

The invention relates to a pain quantitative analysis system and method based on human body physiological signal multi-parameter fusion. The input end of a signal amplifier is connected with a BVP, ECG and SG signal collecting electrode, and corresponding physiological signals of a human body are collected; the output end of the signal amplifier is connected with the input end of a signal AD converter, and the obtained signals are amplified through the signal amplifier; the output end of the signal AD converter is connected with the input end of a signal analysis device, and analog signals are converted into digital signals and then sent to the signal analysis device; a display is connected with the output end of the signal analysis device and receives and displays the signals sent by the signal analysis device. Various physiological signals of the human body are collected, the human body pain intensity is objectively quantized through a mode recognition means, and the system and method have wide application prospects.

Description

Technical field [0001] The invention relates to a medical monitoring quantification device, in particular to a pain quantitative analysis system and method based on multi-parameter fusion of human physiological signals. Background technique [0002] Pain is an unpleasant physiological reaction caused by existing or potential tissue damage, which is generally accompanied by complex pathological and physiological changes, and has an adverse effect on the patient's physical and mental health [1]. As one of the most common clinical symptoms, pain has been identified by the World Health Organization as the five vital signs alongside breathing, pulse, blood pressure and body temperature. In medicine, pain is a symbol of danger signals. The location of pain indicates the focus of the disease. The size and development trend of pain are also indicators of human health. Therefore, how to record the patient’s pain physiological information in time and accurately, and accurately assess and q...

Problems solved by technology

However, these methods generally can only provide qualitative analysis of the presence or absence of pain, and cannot provide accurate pain magnitude, and most of them are evaluations of a single index, which limits the objective quantification of pain.
