Description

Technical Field

[0001] The present invention relates to the technical field of traditional Chinese medicine diagnosis and treatment auxiliary equipment, and particularly relates to a traditional Chinese medicine constitution meridian detector. Background Art

[0002] Meridians are the general term for channels and collaterals. The existence of human acupoints has been detailedly recorded in ancient Chinese medical classics. In 1950, Dr. Yoshio Nakatani, a professor at Kyoto University in Japan, studied acupoints and meridians and, using biophysical methods, confirmed the existence of acupoint points, which he called Ryodoten, and the connected lines through these Ryodoten are called Ryodoraku. These "Ryodoten" and "Ryodoraku" are exactly the same as the positions of acupoints and meridians defined in traditional Chinese acupuncture. After Nakatani's discovery, it has been repeatedly confirmed by medical experts from various countries, laying an objective foundation for the existence of acupoints. Subsequently, he observed that these Ryodoten and Ryodoraku are a form of the internal organs reflecting on the body surface, and signals are measured through skin communication, and further observed whether the functions of the internal organs are normal or abnormal.

[0003] The traditional Chinese medicine constitution meridian detector is designed based on the above theory. It mainly uses GSR (Galvanic Skin Response) technology to collect and evaluate functional information such as the constitution and meridians of the human body. It uses bioelectric scanning technology to determine the internal state of the body by testing the different electrical conductivity of body organs. This device can non-invasively scan the health function state of the human body within a short time (such as three to five minutes), and after comparison with a large database, evaluate its current functional status.

[0004] However, traditional Chinese medicine meridian detection mostly uses single-point or low-density electrodes. When detecting irregular curved surface areas such as the shoulders and waist and abdomen, the signal acquisition is often unstable due to poor electrode adhesion, affecting the accuracy of the detection results. In addition, single-point detection is difficult to comprehensively cover the meridian network, limiting the comprehensiveness and depth of constitution evaluation.

[0005] In the prior art, for example, Chinese Patent No. CN117503096A discloses a traditional Chinese medicine constitution meridian detection system, which discloses a traditional Chinese medicine constitution detection system based on a meridian detection module that can collect and analyze the bioelectric signals and impedance values of meridian acupoints, but does not solve the problems of unstable signal acquisition caused by poor electrode adhesion and the difficulty of single-point detection in comprehensively covering the meridian network.

[0006] As disclosed in Chinese Patent No. CN104970791A, a meridian detector is disclosed, which uses a signal sensor and a signal collector to detect meridian values, and focuses on outputting the detection results through a data processing module. Although it has a certain signal acquisition ability, its technical means are limited to single-point detection, and the problems of unstable signal acquisition caused by poor electrode adhesion and the difficulty of single-point detection to comprehensively cover the meridian network have not been solved.

[0007] As disclosed in Chinese Patent No. CN201658374U, a personal portable meridian energy detector is disclosed, which can be used for body impedance analysis by measuring the DC resistance of acupoint points. Its core technology lies in the portable design and simple single-point DC resistance detection function. However, the technical means of this patent are limited to single-point detection of specific acupoints, and the problems of unstable signal acquisition caused by poor electrode adhesion and the difficulty of single-point detection to comprehensively cover the meridian network have not been solved.

[0008] Therefore, it is particularly important to develop a device that can closely fit complex curved surfaces and achieve high-precision meridian detection and physical constitution evaluation. Summary of the Invention

[0032] First, by using an electrode sheet made of a flexible material, a plurality of sensing electrodes are arranged in an array on the electrode sheet, and the elastic film is deformed to squeeze the air chamber. The air pressure in the air chamber is equal everywhere, so that the electrode sheet is evenly pressed everywhere, so as to closely fit the human body surface for detection, effectively solving the problems of unstable signal acquisition caused by poor electrode adhesion and difficult single-point detection to fully cover the meridian network in the prior art. Furthermore, the electrode detection head can closely fit irregular curved surface areas such as the shoulders and waist and abdomen, ensuring the stability of signal acquisition, and based on the high-density induction network formed by the multi-point array electrodes, by detecting the potential change between different electrodes in real time, the human meridian area can be accurately positioned.

[0033] Second, by pressing the cover plate, the air in the cavity is discharged from the exhaust one-way valve. And, the bottom plate fits the human body surface. After the external force is removed, the elasticity of the deformed elastic ring makes the cavity recover partially. However, the discharged air cannot enter at this time, so that a negative pressure is formed in the cavity. Furthermore, the atmospheric pressure presses on the cover plate, making the silicone rubber ring closely fit the human body, so that the electrode fits more closely to the human body surface, avoiding signal instability caused by loose fitting, and thus improving the accuracy of detection.

[0034] Third, by adding a cavity containing alcohol in the silicone rubber ring, when the silicone rubber ring is pressed, the alcohol flows out from the bottom and flows along the gap between the human body surface and the electrode sheet, so as to completely discharge the air, avoiding the resistance generated by the existence of air from affecting the detection result, and thus improving the accuracy of detection.

The pressing plate 250 is fixedly connected to the elastic membrane 230. The pressing plate 250 is used to drive the elastic membrane 230 to deform.

[0058] Further, the pressing portion 240 further includes an inclined surface tooth 241. The inclined surface tooth 241 is fixedly connected to one side of the pressing portion 240.

[0059] Further, the detection head housing 210 further includes a through hole 211, a sliding groove 212, a limiting slider 213, a return spring 214, a pulling rope 215, and a pulling ring 216;

[0060] The through hole 211 is provided at the center of the top of the detection head housing 210. The detection head housing 210 is used for the pressing portion 240 to slide through;

[0061] The sliding groove 212 is provided on the side wall of the through hole 211. The limiting slider 213 is slidably connected to the sliding groove 212. The limiting slider 213 is used to limit the one-way passage of the inclined surface tooth 241;

[0065] A traditional Chinese medicine constitution meridian detector further includes a power component and a control unit; the power component is used to supply energy for the operation of the detection platform, preferably an alternating current power supply or a battery; the control unit is used to control the coordinated operation of each component of the detection platform, preferably a programmable logic controller; both are prior arts and will not be elaborated here.

[0066] When the traditional Chinese medicine constitution meridian detector of the embodiment of the present application is actually operating, the steps are as follows:

[0067] Place the electrode detection head 200 at the acupoint to be detected on the human body. First, the detection head housing 210 undergoes a preliminary small deformation according to the human body surface, so that the contour of the electrode detection head 200 adapts to the human body surface. Then, press the pressing part 240. The pressing part 240 drives the pressing plate 250 to move downward. The pressing plate 250 pushes the elastic membrane 230 to deform and compress the air chamber. Under the air pressure in the air chamber, the electrode sheet 220 is uniformly stressed and pressed downward everywhere, so that the flexible electrode sheet 220 is completely attached to the human body surface, completing the surface adaptation of the flexible electrode.

[0068] The technical solutions in the embodiments of the present application at least have the following technical effects or advantages:

[0069] By using the electrode sheet 220 made of flexible material, a plurality of sensing electrodes 221 are arranged in an array on the electrode sheet 220, and the elastic membrane 230 is deformed to squeeze the air chamber. The air pressure in the air chamber is equal everywhere, so that the electrode sheet 220 is uniformly pressed everywhere, so as to closely adhere to the human body surface for detection, effectively solving the problems of unstable signal acquisition caused by poor electrode adhesion in the prior art and difficult to comprehensively cover the meridian network by single-point detection. Furthermore, it is realized that the electrode detection head 200 can closely adhere to irregular curved surface areas such as the shoulder and waist and abdomen, ensuring the stability of signal acquisition, and based on the high-density induction network formed by the multi-point array electrodes, by detecting the potential change between different electrodes in real time, accurately positioning the human meridian area.

[0070] Embodiment 2: The close adhesion of the electrode sheet 220 to the human body in the above embodiment depends on the air pressure in the air chamber provided by the downward pressing of the pressing part 240. However, the human body will also generate a reaction force on the electrode sheet 220, which may cause the contact between the electrode detection head 200 and the human body to be not close enough, affecting the stability of the detection signal; the embodiment of the present application is optimized on the basis of the above embodiment.

[0071] As Figure 6 shown, the silica gel ring 260 includes a cover plate 261, a bottom plate 262 and a deformation elastic ring 263. The cover plate 261 and the bottom plate 262 are both annular. The inner sides of the cover plate 261 and the bottom plate 262 are both fixedly connected to the detection head housing 210. The outer sides of the cover plate 261 and the bottom plate 262 are respectively fixedly connected to the upper and lower ends of the deformation elastic ring 263. A cavity is formed between the cover plate 261, the bottom plate 262, the deformation elastic ring 263 and the detection head housing 210.

[0072] Furthermore, the cover plate 261 includes an exhaust check valve 264 and an air release valve 265. The exhaust check valve 264 is used for unidirectionally discharging the internal gas, and the air release valve 265 is used for controlling the entry of external gas.

[0073] The technical solutions in the embodiments of the present application at least have the following technical effects or advantages:

[0074] By pressing the cover plate 261, the air in the cavity is discharged from the exhaust check valve 264. Moreover, the bottom plate 262 fits the human body surface. After the external force is removed, the elasticity of the deformable elastic ring 263 causes the cavity to recover partially. However, the discharged air cannot enter at this time, resulting in a negative pressure in the cavity. Furthermore, the atmospheric pressure presses on the cover plate 261, causing the silicone rubber ring 260 to fit tightly against the human body, thereby making the fit between the electrode and the human body surface closer, avoiding signal instability caused by loose fitting, and thus improving the accuracy of detection.

[0075] Embodiment 3: There may be gaps between the electrode sheet 220 and the human body surface in the above embodiments due to human body hair, dandruff, etc., allowing air to exist and affecting the measurement of the electrical signal by the sensing electrode 221. The embodiment of the present application is optimized on the basis of the above embodiments.

[0076] As Figure 7 shown, the silicone rubber ring 260 further includes a diaphragm 266. The diaphragm 266 is annular. The two ends of the diaphragm 266 are respectively fixedly connected to the cover plate 261 and the bottom plate 262. The diaphragm 266 divides the cavity inside the silicone rubber ring 260 into two layers, and the inner cavity is filled with alcohol.

[0077] Furthermore, the silicone rubber ring 260 further includes a liquid discharge check valve 267 and a liquid injection port 268. The liquid discharge check valve 267 is used for discharging liquid unidirectionally. The liquid discharge check valve 267 is provided on the bottom plate 262. The liquid discharge check valve 267 is communicated with the inner cavity. The liquid injection port 268 is provided on the cover plate 261. The liquid injection port 268 is used for injecting liquid. The liquid injection port 268 is communicated with the inner cavity.

[0078] The technical solutions in the embodiments of the present application at least have the following technical effects or advantages:

[0079] By adding a cavity containing alcohol inside the silicone rubber ring 260, when the silicone rubber ring 260 is pressed, the alcohol flows out from the bottom and flows along the gap between the human body surface and the electrode sheet 220, thereby completely discharging the air, avoiding the resistance generated by the existence of air and affecting the detection result, and thus improving the accuracy of detection.

[0080] The above is only the preferred embodiment of the present invention and is not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
