Description

Technical Field

[0001] The present invention relates to the technical field of meridian electricity data acquisition, and in particular to a motor-propelled adaptive measuring device based on a four-electrode method. Background Art

[0002] Meridians are a type of porous medium channel that exists in the interstitial tissue, has low flow resistance characteristics, and can carry tissue fluid, chemical substances and physical quantities. Meridians can also be called tissue fluid channels with good electrical conductivity. When the flow of Qi and blood is smooth, the electrical conductivity of the meridians is high, and the impedance when the current passes through is small; when the Qi and blood in the meridians are weak (deficiency syndrome), the electrical conductivity of the meridians decreases, and the impedance when the current passes through increases. Changes in impedance can reflect the degree of patency of the meridians and the flow state of Qi and blood. After a lot of research, Qi and blood in traditional Chinese medicine are similar to tissue fluid and blood. The two constitute extracellular fluid. The amount of extracellular fluid can be reflected by bioimpedance spectroscopy technology, which represents the state of Qi and blood in the human body's meridians.

[0003] At present, the "four-electrode method" is used in China as an advanced means of data acquisition. Relying on the equivalent circuit model of biological cell tissue and the equipotential principle, the excitation electrode and the test electrode are separated, effectively isolating the influence of the contact impedance change of the excitation electrode on the test signal, thereby overcoming the error introduced by the surface contact resistance. At the same time, it can deeply collect the overall resistance information of the extracellular fluid and intracellular fluid under the deep structure of the human body, which significantly improves the repeatability and accuracy of the measurement compared with the two-electrode method.

[0004] However, the above technologies are only used in laboratories due to problems such as cumbersome operations and have not been commercially mass-produced. Summary of the Invention

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] See also Figure 1-7 , an embodiment provided by the present invention:

[0027] A motor-propelled adaptive measuring device based on a four-electrode method includes a placement seat 1, an electrode placement compartment 3, a touch switch 4 and a reduction motor 5. The surface of the placement seat 1 is movably connected to a cover plate 2. The surfaces of the placement seat 1 and the cover plate 2 are both provided with through grooves, and the electrode placement compartment 3 acts on the inside of the cover plate 2 and the placement seat 1 through the through grooves. The interior of the placement seat 1 and the cover plate 2 are interlocked and connected with a shell 31. The outer surface of the shell 31 is provided with a fixing hole 32. The interior of the shell 31 is provided with a connecting frame 33. The surface of the connecting frame 33 is movably connected to a rebound compartment 34. The inner wall of the rebound compartment 34 is fixedly connected to a buckle 35. The surface of the connecting frame 33 is fixedly connected to a contact rod. The reduction motor 5 is engaged and connected to the interior of the housing 31. The interior of the housing 31 is fixedly connected to the guide rail 6. The output shaft of the reduction motor 5 is connected to the reducer 51. The surface of the reducer 51 is movably connected to the gear 52. The outer surface of the guide rail 6 is slidably connected to the guide block 72. The surface of the guide block 72 is fixedly connected to the rack 7. The side surface of the rack 7 is fixedly connected to the contact piece 71. The interior of the housing 31 is fixedly connected to the upper limiter 8 and the lower limiter 9. Through the connection between the housing 31 and the connecting frame 33, and the sliding connection between the connecting frame 33 and the rebound chamber 34, the spacing between the electrode sheet placement chamber 3 and the connecting frame 33 can be adjusted, the working angle of the electrode sheet placement chamber 3 can be changed, and its range of use can be improved.

[0028] Furthermore, the electrode placement bin 3 is evenly distributed in the through grooves on the placement seat 1 and the cover plate 2. Through the action of the electrode sheets in the electrode placement bin 3, it can fully contact the human hands / feet. The reducer 51, the upper limiter 8 and the lower limiter 9 are all existing products, and their principles are existing technologies, so no further explanation will be given here.

[0029] Furthermore, the electrode placement bin 3 acts on the top of the outer shell 31 through the connecting frame 33 and the rebound bin 34. A sliding groove is provided on the inner wall of the rebound bin 34. Sliders are fixedly connected on both sides of the connecting frame 33. The connecting frame 33 is slidingly connected to the rebound bin 34 through the sliders and the sliding groove. Through the sliding connection between the connecting frame 33 and the rebound bin 34, the position of the electrode placement bin 3 on the placement seat 1 and the cover plate 2 is changed, thereby improving the adaptability of the electrode placement bin 3 on the placement seat 1 and the cover plate 2.

[0030] Furthermore, the cross-section of the rebound chamber 34 is in a "T" shape, the bottom end of the electrode placement chamber 3 is fixedly connected to a support plate, and the side of the support plate away from the electrode placement chamber 3 is fixedly connected to a fixed block. Through the action of the rebound chamber 34, the action angle of the electrode placement chamber 3 on the rebound chamber 34 is changed, thereby improving the performance of the electrode in the electrode placement chamber 3 and the effect of contact with the skin.

[0031] Furthermore, a through hole is provided on one side of the connecting frame 33 close to the rebound chamber 34, and a buckle 35 passes through the surface of the connecting frame 33 through the through hole. A spring is sleeved on the outer surface of the buckle 35. The connection between the buckle 35 and the through hole prevents the rebound chamber 34 and the connecting frame 33 from separating. Under the action of the spring, an elastic sliding effect is achieved between the connecting frame 33 and the rebound chamber 34.

[0032] Furthermore, the connecting frame 33 and the rebound chamber 34 are elastically slidably connected by a buckle 35 and a spring, the touch switch 4 is embedded in the inner side of the rebound chamber 34, and the contact rod on the connecting frame 33 acts on the bottom of the touch switch 4. Through the contact between the touch switch 4 and the contact rod, the rotation of the reduction motor 5 is controlled. The coordination between the touch switch 4 and the reduction motor 5 is completed through the relevant controller. This is the existing technology, and the touch switch 4 and the reduction motor 5 are both existing products, so no further explanation will be made here.

[0033] Furthermore, the reduction motor 5 is rotationally connected to the gear 52 through the reducer 51, the gear 52 is meshed and rotationally connected to the rack 7, and the upper limiter 8 and the lower limiter 9 are distributed in opposite directions inside the housing 31. Through the action of the contact piece 71 and the lower limiter 9 and the upper limiter 8, the movement position of the rack 7 can be limited, thereby improving its safety performance in use.

[0034] Working principle: the reduction motor 5, touch switch 4, upper limiter 8, and lower limiter 9 are connected to the main control system through the adapter system. The adapter system and the main control system are existing products. Their main function is to receive and feedback signals. The specific working principle is the existing technology and will not be described in detail here. The rack 7 is connected to the reduction motor 5 through the reducer 51 and the gear 52. The main control system sends an open signal, and the reduction motor 5 drives the rack 7 to move forward vertically until it contacts the touch switch 4. At this time, the contact between the touch switch 4 and the contact rod is 0. At this time, the human hand / foot contacts the detection electrode sheet. The touch switch 4 sends a signal to the main control system through the adapter system. After receiving the signal, the main control system sends an instruction to stop the reduction motor 5, and the subject performs meridian detection; after the meridian detection is completed, the main control system sends a close signal, and the reduction motor 5 drives the rack 7 to move back vertically in the opposite direction until it contacts the lower limiter 9, and the reduction motor 5 and rack 7 are reset.

[0035] Redundant safety setting: In order to prevent the rack 7 from falling off due to the hand / foot not being put in and the start switch being turned on, an upper limit switch 8 is set. When the rack 7 moves forward vertically without contacting the touch switch 4 but contacts the upper limit switch 8, the reduction motor 5 stops. At this time, the vertical distance that the rack 7 moves forward is 15 mm.

[0036] Reset setting: When the main control system sends a shutdown signal, the reduction motor 5 drives the rack 7 to move back vertically in the opposite direction. At this time, the human hand / foot and the detection electrode sheet are separated from each other. Under the action of the spring, the rebound between the rebound chamber 34 and the connecting frame 33 is triggered, and the rack 7 and the touch switch 4 are separated, completing their respective resets.

[0037] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be included therein. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
