Abstract

The present invention discloses a method and a circuit for correctly measuring human acupoints by frequency modulated signals which act on a body by the divergence of the human acupoints to excitation signals. A frequency modulated signal has a coupling effect on a human body by amplification; simultaneously, a direct current level signal is sampled by rectification; when detected, a human acupoint is reinforced, detected and outputted by feedback; simultaneously, the direct current signal is outputted by a sampling circuit for indicating the acupoint point.

Description

A kind of circuit of surveying human acupoint

The present invention relates to a kind of method and circuit of new detection human acupoint, relate to a kind of medical electric treatment, health care instrument simultaneously, especially can survey electronic therapy, the health-care appliance of human acupoint.

From the fifties in this century, people just begin to adopt modern electronic technology to carry out the research of human acupoint and meridians detection, attempt to develop a kind of instrument, can indicate the position and the distribution of human acupoint exactly.At present, known this quasi-instrument kind is a lot, and these instruments generally adopt resistance method of temperature measurement promptly to measure dc resistance between 2 of the human bodies, when its during less than a certain setting value, an agitator is opened shake to provide buzzing or light shows.For example " the human acupoint exploration instrument " of Guangzhou production judges the acupuncture point by the reading of microampere meter, " current intensity big then for the acupuncture point " (being that more then measured point resistance is littler for current intensity), the ultimate principle of above-mentioned instrument foundation is with the understanding for " acupuncture point of human body is low resistance characteristic ".

The acupuncture point of human body really is low resistance characteristic, but anti-quite different, and the position that promptly not talkative human body is low resistance characteristic all is the acupuncture point.The most tangible illustration is, when human body a part injured or water-filling, when congested, this position can entirely present low resistance, therefore says that this position all is that the acupuncture point obviously is invalid.The size of human acupoint D.C. resistance varies with each individual; Because of man, woman, old, young different; Even if same people is also different because of the position difference, season is different and different; The height of resistance and low just relative notion in addition, therefore, based on this " acupuncture point of human body is low resistance characteristic " the theoretical detection method and the instrument of development, the detection of carrying out human acupoint is impossible accurately, also is not enough science.

Searching can be represented the electrical characteristics of human acupoint feature in addition, and just might propose the Method and circuits of new accurate detection human acupoint in view of the above.A large amount of scientific experiments and discover that human acupoint shows a kind of special " divergence characteristic " under the effect of bipolarity detectable signal.The present invention is just according to " divergence characteristic " this important discovery as the human acupoint feature, thereby the bipolarity signal of telecommunication of employing adjustable frequency acts on human body and differentiates the purpose that its divergence degree reaches accurate detection human acupoint automatically.

The present invention is achieved in that (referring to accompanying drawing)

The bipolar signal source (X) of an adjustable frequency produces the bipolarity signal of telecommunication.This signal amplifies through automatic gain control amplifier U1, exports in order to survey the detectable signal of human acupoint through coupling transformer (Y) after signal driver U2 drives again.Carrying out human acupoint when surveying, the A utmost point in two output stages is being fixed in some with reference to acupuncture point or reference site and carry out point detection with another probe utmost point on human body, at this moment detectable signal is added to human body, and the while, output loop was by UNICOM.The ambipolar probe current signal of human body of flowing through is flowed through simultaneously and is serially connected in rectification circuit Z and sampling resistor R2 in the output loop, is transformed into d. c. voltage signal and is sampled.The d. c. voltage signal that is sampled enters sampling amplifier U3 and amplifies after RC filtering.When accurately detecting human acupoint, because the acupuncture point to the divergence characteristic that detectable signal showed, makes the electric current of the human body of flowing through sharply become big, the variable quantity of sampled signal sharply increases.A change amount signal input comparison amplifier U4 and a reference value after U3 amplified compare, and when change amount signal during greater than this reference value, when the divergence that also promptly reaches setting is spent, are judged as the acupuncture point feature.At this moment, comparison amplifier U4 just has the variable quantity signal output of a positive phase.This positive variable quantity signal feedback to the positive terminal (C) of automatic gain control amplifier U1 and bipolar signal same phase stack from signal source (X), is increased the intensity to the detectable signal of human acupoint automatically, also increased measured's acupuncture point sense automatically.The output of U4 simultaneously is added to U5 and carries out the integration amplification.The dc level signal that U5 output one has been amplified, it is proportional to the variable quantity of dispersing electric current.This level signal can be delivered to display driver circuit and directly control demonstration, also can become digital quantity signal and send Computer Processing through A/D conversion or V/F conversion etc.

Be serially connected with signal driver U2 and be used for amplitude limit to the R1 between coupling transformer (Y), control does not make excessive detectable signal add the what human body.

The present invention is according to detection method and circuit that a kind of brand-new human acupoint is provided as " the divergence characteristic " of human acupoint feature, and with the detection indication of instrument and measured's acupuncture point sense (traditional Chinese medical science is differentiated the sole criterion at acupuncture point: i.e. acid, fiber crops, expand, scurry, feeling of qi such as acupuncture, radiation) develop simultaneously, thereby can survey the acupuncture point of human body exactly.

Accompanying drawing is to utilize " divergence characteristic " to survey the embodiment circuit diagram of human acupoint.

Below in conjunction with accompanying drawing, make embodiment and describe:

The bipolarity electric signal source of adjustable frequency passes (X) and produces the bipolarity signal of telecommunication, and when U1, U2 arrived the D point, its peak-to-peak value voltage was Vp-p=0.6V, and again through coupling transformer (Y), output bipolarity detectable signal acts on human body.The bipolarity probe current of human body of flowing through is flowed through simultaneously and is serially connected in rectification circuit Z in the output loop by rectification and be sampled resistance R 2 samplings and be transformed into d. c. voltage signal, amplifies through RC filtering, U3 again, exports a direct current voltage signal.When accurately detecting the acupuncture point, the variable quantity of sampled signal sharply increases, this variable quantity enters comparison amplifier U4 and reference voltage value compares, surpass the reference voltage value part and be fed point to C, with from the bipolar signal of signal source X with superimposed finally to the detectable signal increasing that A order, but because the metering function of current-limiting resistance R1, make the detectable signal that acts on human body can be not excessive, the output of U4 is simultaneously carried out integration through U5 and is amplified, the driving LED display driver shows the acupuncture point of point detection state and correct indication human body in order to the row's of driving light emitting diode.
