Description

A multi-modal integrated closed-loop active health system and method

Technical field

The present invention relates to the technical fields of active health and medical instruments, and in particular to a multi-modal integrated closed-loop active health system and method.

Background technique

As the average life expectancy of humans continues to increase, chronic non-communicable diseases ("chronic diseases") such as frozen shoulder, cervical spondylosis, and lumbar disc herniation and sciatica have gradually become major threats to health. "Active health" can be considered as a kind of long-term continuous dynamic tracking of the individual's entire life cycle behavior system, the identification and evaluation of one's own status, evolution direction and degree, and the comprehensive use of various medical means to control human behavior. Early active intervention promotes self-organized adaptive changes in the human body, thereby achieving a medical model that improves function, eliminates diseases, and maintains human health. Therefore, the development of active health systems has become key to the development and transformation of modern medical research.

Traditional Chinese medicine is a health intervention technology with Chinese characteristics. Since the 1970s, a large number of clinical experiments have proven that acupuncture therapy based on meridian theory has significant effects on many diseases. Along with further research on meridian theory, the standardization of acupuncture points has improved the reliability and reproducibility of acupuncture research, thereby increasing the understanding of the mechanism of acupuncture in treating clinical symptoms or diseases. As more and more clinical evidence was discovered, researchers began to explore the mechanism of acupuncture's action on acupoints, and developed various forms of modern acupoint therapy, such as acupoint electrical stimulation, acupoint light stimulation, and acupoint thermal stimulation. Multimodal physical stimulation therapy for acupoint therapy has emerged as an improved interdisciplinary treatment approach. Therefore, multi-modal meridian physical stimulation devices combined with physiological signal monitoring have also become an important research direction for active health systems.

For example, the patent number is CN115588509B, a multi-modal breast health detection system. This system uses a feature matching module to identify and match the identity characteristics of the tester, and generates a matching success signal or a matching failure signal to facilitate the verification of the identity information of the tester. After passing the verification, real-time monitoring data are used to monitor the breast health status of the inspector in real time, and the status deviation value of the inspector is obtained and sent to the level setting module. The level setting module combines the status deviation value to set the detection level of the inspector. After obtaining the testing level of the testing personnel, the server sets the corresponding testing intensity for the testing personnel based on the testing level and sends it to the testing comparison module. The testing comparison module compares the breast health of the testing personnel based on the number of testing, and compares the testing personnel based on the number of testing. The real-time breast monitoring data is substituted into the breast detection model to generate a breast diagnosis signal or no operation is performed, and the intensity of breast detection of the detection personnel is set based on actual factors, thereby improving the accuracy of breast health detection. Although this invention solves the technical problem of setting the breast detection intensity of the examiner based on practical factors, thereby improving the accuracy of breast health detection, the physiological signal monitoring method is single and the range of diseases targeted by the system is small. During the application process The limitations are greater.

For example, the patent number is CN106548011A, a multi-modal mobile health real-time monitoring system. This system is different from other wearable devices in that it collects multiple health indicators to form a one-dimensional array. In the time domain, over time, a large number of discrete arrays are collected, and multiple arrays are brought into the multi-modal correlation vector regression machine to obtain a health indicator (ie, multiple inputs and single output). Although this invention realizes a wearable and multi-modal human health monitoring, it can provide timely feedback and use a mobile health system with a wide range of effectiveness. However, in the health intervention process, the physical stimulation method is single, and the system cannot achieve the best effect of health intervention through multi-modal physical stimulation, making it difficult to realize the closed-loop use of the integrated system.

That is, the current active health system still has the following problems. First of all, most active health systems that combine physiological signal monitoring with health intervention are limited by a single method of physiological signal monitoring, which increases the probability of misdiagnosis. The reliability of the system is not high, and it is not an active intervention method. At the same time, the single monitoring method leads to a narrow range of diseases targeted by the system, and the active health system has great limitations in the application process. There is no active health system on the market for chronic diseases such as cervical spondylosis, frozen shoulder, lumbar disc herniation, sciatica, etc. system. Secondly, in the health intervention process, the physical stimulation method is single, and the system cannot achieve the best effect of health intervention through multi-modal physical stimulation. Currently, the only systems that combine physiological signals with health intervention are affected by the way physiological signals are monitored and cannot use multi-modal physical stimulation to perform health intervention on users. Finally, most active health systems need to be used with the cooperation of doctors, are difficult to operate and expensive, and it is difficult to achieve closed-loop use of integrated systems.

Therefore, it is necessary to propose a multi-modal integrated closed-loop active health system and method, which on the one hand solves the difficulties existing in the existing technology, and on the other hand actively and intelligently intervenes in people in sub-healthy states to reduce the occurrence of diseases. Problems that those skilled in the art urgently need to solve.

Specifically, the multi-modal physiological signal monitoring module includes a pulse blood oxygen monitoring sensor, a surface electromyographic signal monitoring sensor, an acupoint surface temperature monitoring sensor and an acupoint surface electrical impedance sensor.

The pulse oximetry monitoring sensor uses near-infrared spectroscopy to non-invasively monitor blood oxygen saturation and pulse wave signals below the acupuncture points. The blood oxygen saturation monitoring sensor is composed of a green LED (wavelength 500-600nm) and two infrared LEDs (wavelength 800-820nm and 830-850nm) with good monochromaticity (or filter packaging) It consists of a combined light source, a photosensitive diode (or a photosensitive diode with a filter package) whose response range corresponds to the wavelength of the light source, and a signal conditioning circuit. The light source and photodiode are placed on the same side of the tissue and fixed at the preset acupuncture points using a fixation device. They can be used together with the multi-modal health intervention module. Among them, the green light spectrum in the 500nm-600nm range has a high reflectivity and can obtain clear reflective photoplethysm waves; while the infrared light in the 800nm-820nm range has a deeper penetration depth and can clearly detect deep arterial blood flow. Information; Infrared light in the 830-850nm range is used to monitor the redox activity of cytochrome C oxidase under acupuncture points to assist in evaluating the effect of physical stimulation. The signal conditioning circuit is used to amplify and filter the signals collected by the photodiode, and consists of an amplification circuit and a filter circuit.

Acupoint surface temperature monitoring sensors are used to monitor temperature changes at acupuncture points, and are divided into two measurement methods: electrical and optical. The optical acupoint surface temperature monitoring sensor is composed of a miniaturized infrared thermal imaging module and a signal conditioning circuit. Among them, the miniaturized infrared thermal imaging module has an operating wavelength of 7-14 μm, a temperature measurement accuracy of 0.01°C, and a temperature measurement range not limited to 30-50°C. It is attached to the skin surface and can be used in combination with the physical stimulation module. The signal conditioning circuit is used to amplify and filter the collected acupoint surface temperature signals.

Among them, the measurement accuracy of high-precision thermistor is 0.01℃, and the measurement range is not limited to 30-50℃. The signal conditioning circuit is used to amplify and filter the collected acupoint surface temperature signals.

The surface myoelectric signal monitoring sensor is an optical surface myoelectric sensor or an electrical surface myoelectric sensor, which is used to monitor whether the activity level of muscle bundles decreases due to the occurrence of local inflammation and the activity level of the muscle after health intervention. The optical surface electromyography sensor consists of a sensing light path, a photoelectric detector and a signal conditioning circuit, and can be used with meridian electrical stimulation, meridian light stimulation and meridian thermal stimulation devices. The sensing optical path includes fiber light source, polarizer, polarization controller and electro-optical modulator. The basic principle is that the light emitted by the optical fiber light source enters the electro-optical modulator after passing through the polarizer and polarization controller. The surface electromyographic signal is loaded on the electrode of the electro-optical modulator, which modulates the light intensity passing through the modulator. By measuring the change in light intensity value with the photodetector, the loaded voltage change can be obtained, thereby achieving the acquisition of surface electromyographic signals.

The measuring electrode is a patch electrode, which is placed at the end of the muscle bundle where the acupuncture point is stimulated. Surface electromyography is a weak bioelectric signal, which originates from the excitement of the muscles or nervous system. The main signal frequency is concentrated at 50-150Hz and the amplitude is 0-6mV. Therefore, a conditioning circuit is required for amplification and filtering. The signal conditioning circuit is used to amplify and filter the collected surface electromyographic signals, and consists of a preamplifier, a low-pass filter, a 50Hz notch and a post-amplifier circuit.

The acupoint surface electrical impedance sensor is only used to monitor changes in skin surface electrical impedance at acupuncture points. It consists of a skin surface electrical impedance monitoring probe and a signal conditioning circuit. It monitors the change amount rather than the absolute value. The skin surface electrical impedance monitoring probe consists of a 6*6 high-sensitive electrical impedance probe array and a fixed device. It is attached to the skin surface and can collect up to 36 channels of acupoints and electrical impedance information around the acupoints. When the skin surface electrical impedance sensor is used for stimulation assessment, it conflicts with the meridian electrical stimulation signal, so it can only be used in combination with meridian light stimulation and meridian thermal stimulation devices. The signal conditioning circuit is used to amplify and filter the collected electrical impedance signal.

The computing processor will calculate the physiological signals collected by the multi-modal sensors stored in the memory according to the built-in algorithm, and evaluate the user's health status. When a user has a health risk, the computing processor will identify the disease type based on the data and send the calculated physiological parameters and warning signals to the transmission sub-module. At the same time, it will select specific acupoints based on the built-in treatment plan and send drive signals to the transmission sub-module. .
