Description
Technical Field
The invention relates to the technical field of meridian detection, in particular to a meridian detection device for multipoint polling sampling.
Background
The theory of meridians is one of the core of basic theory of traditional Chinese medicine, and meridians are the channels for qi and blood, viscera, body surface and all parts of the whole body, and are the regulation and control system of human body functions. The meridian science is also the basis of acupuncture and massage of human body, and is an important component of traditional Chinese medicine.
The meridians are the general names of meridians and collaterals, and TCM considers that the meridians belong to viscera and collaterals are located in the limbs, and can be communicated with the interior and exterior of the body surface. Specific collaterals are present between the meridians and viscera, and acupoints are the specific locations of the viscera where qi and blood of the meridians infuse. Therefore, the method can reflect the trend of the channel change of the human body for the acquisition and analysis of the electrical signals of the human body acupoints, is used for helping to judge the health condition of the human body, and provides support for judging various uncomfortable symptoms, disease causes and future disease development situations of the human body.
The existing meridian sampling equipment is divided into two types: the original point sampling method comprises two electrodes, and measuring the impedance of the points and neutral points; one is multi-acupoint sampling, automatic switching can be performed between acupoints, but the neutral point is the same fixed point. Then, the acquired impedance values of the acupoints and the neutral points are adopted for calculation, and a detection report is output. In addition, the current meridian collection is mostly single source detection, namely single alternating current source detection or single direct current source detection. Thus, the existing meridian sampling apparatus has the following problems: (1) Based on different acupoints, only a single sampling is performed for the same reference point, and flexible sampling can not be automatically performed among different acupoints, so that the number of sampling samples is lacked, and sampling data has limitations; (2) Continuous sampling is carried out on the same acupoint, so that the stored energy of the acupoint can not be discharged, and continuous repeated measurement is caused, and the detection result is abnormal; (3) The initial state of the acupuncture point of the human body is not measured and judged, and the initial state of the acupuncture point cannot be recovered after the measurement is finished; (4) At present, the main and collateral channels are collected and mostly detected by a single source, and the detection of an alternating current source and a direct current source cannot be carried out at the same time; (5) The sampling algorithm only calculates for single meridian impedance, and the algorithm is limited.
It is apparent that the above-mentioned existing meridian detection apparatus still has inconvenience and defects, and further improvement is needed. The novel multi-point polling and sampling meridian detection device can be established, so that the device can realize measurement of a single acupoint to neutral detection points, can realize impedance measurement between any two acupoint points, can also measure the initial state of the acupoint before measurement, is convenient for recovering the initial state of the acupoint after measurement is finished, has a bleeding function so as to realize continuous repeated measurement, can realize single direct current source and single alternating current source, and can realize direct current and alternating current superposition detection, is simple and convenient to switch in multiple modes automatically, has an accurate structure, and becomes an urgent target for improvement in the current industry.

Description of the embodiments
Referring to fig. 1 and 2, the meridian detection device for multi-point polling sampling in this embodiment includes a plurality of acupoint detection terminals 100, a function switching module 200 connected to the acupoint detection terminals 100, a signal processing and voltage sampling module 300 connected to the function switching modules 200, a lower computer data processing and control module 400, an upper computer data processing and control module 500, an algorithm data processing module 600, and a cloud platform 700.
The plurality of acupoint detecting terminals 100 include a neutral point detecting terminal 150, and other acupoint detecting terminals such as a channel 1 acupoint detecting terminal, a channel 2 acupoint detecting terminal … … and a channel N acupoint detecting terminal.

The neutral point detecting terminal 150 is in contact with a neutral point detecting point like the neutral point of a conventional detecting circuit. The neutral point detecting terminal 150 has the same function as the other acupoint detecting terminals 100, but adopts a different external structure different from the other acupoint detecting terminals 100, so that the neutral point detecting terminal is convenient to distinguish and confirm in use.
As shown in fig. 2, the function switching module 200 includes a neutral zero connection channel 201 and a positive and negative voltage connection channel 212. The neutral zero point connection channel 201 is an output channel connected with the neutral zero point 204 through the relay 202, the relay 202 is used for controlling the neutral zero point connection channel 201 to be connected with neutral zero potential, and the relay 202 is in an off state under normal conditions; if the relay 202 is closed, the neutral point connection channel 201 is turned on, and the connection channel 201 serves as a neutral point for measuring the impedance value of other channels relative to the neutral point. When the neutral zero point connection channel 201 is connected with the neutral detection end 150, the relay 202 is in a suction state under normal conditions; if the relay 202 is open, the neutral detection terminal 150 is not engaged in operation or is in a recovery initialization state.

And the neutral zero point connecting channel 201 and the positive and negative voltage connecting channel 212 have the functions of static electricity protection, interference resistance and the like, and can ensure the stable operation of equipment.

The signal processing and voltage sampling module 300 is connected with the positive and negative voltage connection channels, and is used for collecting detection signals of detection channels formed by any two acupoint detection ends 100 and the function switching modules 200 correspondingly connected with the acupoint detection ends, and transmitting the detection signals to the lower computer data processing and control module 400. Specifically, the signal processing and voltage sampling module 300 divides the detection signal into a direct current signal acquisition and an alternating current signal acquisition by filtering, and transmits the acquired signals to the lower computer data processing and control module 400.
The lower computer data processing and control module 400 processes the signals by collecting the signals of the signal processing and voltage sampling module 300 and transmits the signals to the upper computer data processing and control module 500; the lower computer data processing and control module 400 may also receive the control instruction of the upper computer data processing and control module 500, and execute the corresponding action instruction.
