Abstract

A diagnostic pencil for detecting acupuncture point of ear is a kind of medical device. The utility model manufactures the diagnostic pencil for detecting acupuncture point of ear on the ground of the mechanism and principle of diagnostic method for acupuncture point of ear in traditional Chinese medicine. It is mainly composed of the electronic elements including a probe, an adjusting resistor, a light-emitting diode, a pen-buckle-type switch and a direct current power supply, etc. When using it, it is required to hold the detecting diagnostic pencil just by hand to do the detection and diagnosis for acupuncture point of ear and break through the channel. It has small volume and little weight, and it is easy in use and carry over.

Description

Diagnostic pencil for detecting acupuncture point of ear

Ear acupoint detection diagnosis pen is a kind of medical apparatus and instruments.

The ear treatment method that China's traditional Chinese medical science is traditional is to adopt desktop detector of auricular acupoints, when a certain position of human body is ill, can occurs impedance at the corresponding acupuncture point of auricle and reduce phenomenon, produce sensitive spot, and normal position and sensitive spot has tangible difference.According to these characteristics, desk-top detector of auricular acupoints allows the patient hold an electrode when surveying, and the doctor holds detector bar and slowly slides on patient's auricle.When finding sensitive spot, the loudspeaker of survey meter send sound equipment or display lamp is bright.This survey meter price height, volume is big, and electrode is external, and the plug-in unit lead fractures easily, makes troubles to user.

The purpose of this utility model is the mechanism principle according to the ear treatment method, provides a kind of volume little, in light weight, carries and ear acupoint detection pen easy to use.During use, as long as the hand-held diagnosis pen of surveying just can carry out the ear acupoint detection diagnosis.

The technical solution that realizes above-mentioned purpose is: the shell of a pen shape of design, in the shell probe 1 is housed, adjusts resistance R 23, spring 4, light emitting diode 5, pen button double as switch and electrode 7, battery 8, battery spring 9, bonnet 10 and by biasing resistance R2, current-limiting resistance R3, multiple tube BG1, the circuit board 6 that BG2 forms.During use, doctor's hand thumb is by the pen button, and power supply is promptly connected, the auricle that left hand thumb forefinger helps patient to survey.Probe slides at patient's auricle, and transistor bias circuit constitutes.When not visiting ear acupoint sensitive spot, skin of pinna resistance is relatively large, and promptly biasing resistance is big, and bias current is little, transistor BG1, and BG2 ends, and at this moment transistor collector has only small penetrating current Iceo to pass through.So light emitting diode does not work.When visiting ear acupoint sensitive spot, point skin is relatively little, i.e. bias current is big, and base stage is in forward bias, transistor BG1, the BG2 conducting is by current-limiting resistance R3, making the electric current by light emitting diode is 1 milliampere, and light emitting diode is shinny, thereby reach the ear acupoint is diagnosed and dredge the meridian passage.

This utility model compared with prior art, novel structure is simple, volume is little, power consumption is low, and is highly sensitive, greater than 10 megohms; Easy and simple to handle, to produce easily, manufacturing cost reduces, and is easy to use and carry.

Accompanying drawing 1 is a structure external form sketch map of the present utility model.

Accompanying drawing 2 is circuit theory diagrams of the present utility model.Wherein R1 is for adjusting resistance, according to weather and each doctor's different can the adjustment of skin resistance; R2 is the transistor biasing resistance, and R3 is a current-limiting resistance, and BG1 and BG2 are multiple tube, and LED is a light emitting diode, and K is metal pen button double as switch and electrode, and E is a dc source.

The utility model is described in further detail with an embodiment below in conjunction with accompanying drawing.

Referring to Fig. 1, probe 1 is contained in the insulation crust 2 front end tapers, and a cavity is arranged in the shell 2, end near probe 1, join with adjustment resistance 3, the other end of resistance 3 and a spring 4 one ends join, and the other end and the circuit board in the testing circuit 6 of spring 4 join, testing circuit is by light emitting diode 5, circuit board 6, a button switch double as electrode 7, dc source 8, battery spring 9, bonnet 10 formations such as grade.Light emitting diode 5 in the testing circuit is contained in the front end of cylinders in the middle of the shell 2,, a transparent window is arranged here, in order to observe whether starter of diode.Testing circuit plate 6 is by cylinder rear end in the middle of the crust of the device 2.The battery 8 of testing circuit is placed in the Cylinder of back, battery contact piece is equipped with at the two ends of battery 8, join with testing circuit wiring board 6 respectively, the switch of testing circuit is buckled 7 double as switch and electrodes by pen, and pen button 7 is contained in the front end of battery spring 9, joins with battery contact piece, buckle 7 back at pen spring 9 is housed, when bonnet 10 is connected to shell 2 by spiral, because the pressure of spring, forms reliably and be electrically connected.Probe 1 usefulness φ 3mm brass wire is made, No. 5 battery springs of battery spring 9 usefulness, and spring 4 usefulness φ 3mm brass wire springs, battery contact piece is made of thick 0.3-0.5mm latten(-tin).

With reference to Fig. 2, R1=5M Ω, R2=380K, R3=8.2K, BG1, BG2=9011 or 3DG6, LED select red, the green light emitting diode of diameter 3mm for use, E=9～12 volt battery can be selected φ 10 * 28mm electronic striking machine battery for use, or saves with φ 7.9 * 3.6mm button cell 8.

Points for attention:

1. battery polar can not be adorned instead, battery negative terminal inwardly, anode is outwardly.

2. patient's auricle has water to dry.

3. Please Return After Use, and pen closes, and the pen button is answered the side position, can not make progress, and is pressed in pen button, consuming cells in order to avoid close lid.

4. when using for the first time, please probe gently be contacted with the palm back of the body with the left hand facies palmaris respectively user, if a diagnosis one side is bright, one side does not work, and then resistance R 1 suitable the use adjusted in explanation, otherwise needs to adjust.
