Description
Technical field
The utility model relates to a kind of tcm clinical practice detection devices, and in particular to a kind of hand-held impedance of point detector.
Background technique
Bio-impedance (electrical bio-impedance) technology is that a kind of electricity using biological tissue and organ is special
Property and its variation, extract the lossless decomposition technology of relevant to Human Physiology, pathological condition biomedical information, it is usually
It is sent into a small measurement current or voltage to test object by the electrode for being placed in body surface, detects corresponding electrical impedance and its change
Change situation and obtains relevant physiology and pathological information then according to different application purposes.The technology has noninvasive, cheap, peace
Entirely, the features such as nontoxic, easy to operate, abundant information, doctor and patient are easy to receive.
Acupuncture point, scientific name acupuncture points on the human body refer to the special position Dian Qu of the skin surface of human body, i.e. skin surface characteristic point, general point
For through cave, extra nerve points, i.e. points not mentioned in the ancient medical classics, Ashi Point, four class of the ear acupuncture point.Most of acupuncture point is located on flow routes of the meridians.Chinese medicine by acupuncture or can push away
It takes, press, the toast that ends stimulates corresponding channels and collaterals point treatment disease.Acupuncture point is Chinese culture and the distinctive noun of traditional Chinese medicine, mostly mind
Through the more place of tip and blood vessel.
It was found that the bio-impedance values at acupuncture point are lower than non-acupuncture point.And when disease, the bio-impedance at corresponding acupuncture point occurs in human body
Value can change, therefore the variation tendency of the bio-impedance values by monitoring acupuncture point, very easy can intuitively grasp people
The health condition of body.But the bio-impedance values at acupuncture point can be measured currently without instrument.
Theory of traditional Chinese medical science is formed in the Spring and Autumn and the Warring States Periods, and application has more than 2,000 years so far.But from doctor trained in Western medicine enter China with
Afterwards, people start to query Chinese medicine with the thoughtcast of western medicine system, or even traditional Chinese medicine is made to fall into striving of depositing and give up
Among.One of basic reason is that the diagnostic result and validity of Chinese medicine are largely dependent upon the subjectivity of doctor
Judgement.How to make the diagnosis index of Chinese medicine more objective and have diagnosis reference value, is the breach of modern Chinese medicine development.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of hand-held impedance of point detectors, it can be accurate
