Description

The scan-type acupuncture point detector

Under technical field this utility model relate to a kind of electron detection device of indicating human acupoint to exist, especially it has automatic adaptation human body difference and can mark a kind of human acupoint detector at acupuncture point automatically.

Background technology is well-known, and the resistance at human acupoint place has tangible low resistance in non-acupuncture point relatively on every side.The human acupoint detector of knowing according to this principle the present is to be linked to each other by single probe, current potential comparison circuit and audible-visual annunciator to form.When probe contact epidermis, allow the measuring resistance in the potential comparator form dividing potential drop with the top layer skin resistance, the current potential that dividing potential drop produces is compared with the potential comparator preset threshold, be lower than threshold value as if current potential and just be judged to the acupuncture point and send sound and light alarm.

This method needs to regulate repeatedly in advance threshold value, and can be because of individual variation, and factors such as temperature and moisture variation make the fault rate of judgement higher, also can't mark the acupuncture point automatically.

Summary of the invention can not adapt to the deficiency that human body difference can not be made labelling at the acupuncture point automatically in order to overcome existing single needle formula acupuncture point detector, this utility model provides a kind of multiple-pin type scanning acupuncture point detector that need not artificial setting threshold: it has solved the difficulty of setting threshold easily, is measuring acupuncture point energy automatically dotting simultaneously.Therefore it be one from the measuring principle to the method on all different acupuncture point detection devices.

The technical scheme in the invention for solving the technical problem is: by 8 hollow metal tubes scan electrode that forms a line, voltage has constituted a potentiometer through scan electrode by a measuring resistance when contacting skin, the partial pressure potential on it is directly proportional with skin resistance.Current potential on 8 electrodes is sent into A/D converter by electronic analog swtich scanning successively and is quantized into numerical value.Single chip microcomputer reads in quantized value from bus, and 8 potential values that scan are each time found out wherein minimum point, spend the minima averaging method then and obtain the resistance ratios of it and surrounding skin, if this ratio is (annotate 1.: statistical value is 56%) within the specific limits, then be judged to the acupuncture point, otherwise do not consider.Floating number of using during its computing and logic discrimination program all are stored in the eprom memory, differentiate the result drives audible-visual annunciator and striking mechanism from microcontroller bus coil actuator, traveling electrode scan skin during use, light emitting diode matrix promptly can be indicated the position, acupuncture point, voice guard is reported to the police behind the affirmation acupuncture point, and striking mechanism can be marked on the acupuncture point on the skin automatically.

The beneficial effects of the utility model are: the multiple-pin type scan electrode should be gone into and the strange land is automatically made reference threshold with meansigma methods, differentiate with the relative ratios and to come the offset measurement error, so its little manually setting threshold, be not subjected to the influence of extraneous factor yet, when measuring, inject the electric current at acupuncture point less than 1.5 microamperes, can not change the acupuncture point physiological status, thus the reliability height, easy to use be a kind of more perfect human acupoint sniffer.
