The present invention is described in further detail below in conjunction with the embodiment given by accompanying drawing.
Referring to figs. 1 to shown in 4, a kind of nerve detecting instrument of the present embodiment, it is characterised in that：Including detection pin 1 and electric current
Generator 2, the detection pin 1 is used to insert to be in contact with the nerve of people into the human body, and the current feedback circuit 2 is used to send thorn
Swash electric current, the detection pin 1 electrically connects with current feedback circuit 2, and detection pin 1 receives the stimulating current of the output of current feedback circuit 2 simultaneously
It is passed in nerve, the current feedback circuit 2 includes shell 21 and the current circuit 22 being arranged in shell 21, the electric current electricity
Road 22 includes power supply 221, oscillation generating circuit 222 and range-adjusting circuit 223, the power supply 221 and range-adjusting circuit 223
Coupled with oscillation generating circuit 222, wherein, the output current of power supply 221 vibrates in oscillation generating circuit 222, after be input to
Adjustment oscillation amplitude in range-adjusting circuit 223, the power supply 221 are rechargeable battery, and the oscillation generating circuit 222 includes shaking
Chip U1 is swung, vibration chip U1 has high-triggering end, low triggering end, discharge end and an output end, the high-triggering end and low
It is grounded, is also coupled to after the variable resistor R2 and resistance R1 that are serially connected and electricity after being coupled with electric capacity C1 after the mutual short circuit of triggering end
Source 221 couples, and output end is coupled to range-adjusting circuit 223, in outputting oscillation signal to range-adjusting circuit 223, institute
Range-adjusting circuit 223 is stated to be coupled with mutually including comparator U2 and adjustable resistance R6, the in-phase input end of the comparator U2
The output end that electric capacity C3 is coupled to vibration chip U1, the resistance R3 are coupled with after resistance R5, the resistance R4 and resistance R3 of series connection
It is grounded after being coupled with electric capacity C4, the resistance R4 is grounded after being coupled with electric capacity C5, and the resistance R5 is grounded after being coupled with electric capacity C6,
The reverse inter-input-ing ending grounding of the comparator U2, its output end, the comparator U2 are coupled to after being further coupled to adjustable resistance R6
Output end be coupled to detection pin 1, the signal after output adjustment is entered in detection pin 1, the output end coupling of the comparator U2
It is grounded after being connected to resistance R6 and LED D, the LED D is set on the lateral wall with shell 21, and LED D receives comparator U2
The signal of output end output, as signal lights, when using the nerve detecting instrument of the present invention, detection pin 1 is inserted first
Enter into the body of people to be detected, and the syringe needle for detecting pin 1 is in contact with the nerve in body, then occurred again by electric current
Device 2 sends stimulating current to detecting in pin 1, is then delivered to by detecting pin 1 in nerve, and nerve will produce nerve impulse,
So that the body corresponding to the nerve acts because of nerve impulse, so just can be good at realizing using to neural transmission electricity
Stream causes nerve to produce the mode of nerve impulse and judge that nerve is specifically the effect of which root nerve to realize, and occurs in electric current
It is by being to pass through power supply first when producing caused by the current circuit 22 in it during device 2 produces electric current
221, which send electric current, is input in oscillation generating circuit 222, then after oscillation generating circuit 222 is converted into the electric current of vibration

When appearance C1 voltages are increased to the evoked potential of high-triggering end, vibration chip U1 discharge end is opened, and electric capacity C1 will pass through
Variable resistor R2 is discharged, and when going out the evoked potential of originator with discharging into, electric capacity C1 can be recharged again, so real well
Show the effect repeatedly to vibration chip U1 input signals, and when high-triggering end and low triggering end reach evoked potential,
Vibration chip U1 output end will export high level and low level respectively, just can so export a square wave, so very well
The oscillating modulation realized to electric current, it is simple in construction, and the vibration chip used in the present embodiment is 555 timers, because
And its compact is simple in construction, after the square wave of vibration chip U1 outputs runs past resistance R5, resistance R4 and resistance R3 afterwards
Enter in the scaling circuit of comparator U2 compositions, due to being connected between comparator U2 in-phase input end and output end
Adjustable resistance R6, thus can be by changing adjustable resistance R6 resistance, to change the multiplication factor of scaling circuit, so
Realize an adjustment and be finally output to detect the effect of the oscillating circuit amplitude in pin 1, and set by LED D, it is possible to
By being lighted according to the frequency of oscillation and amplitude of oscillating current to being passed through oscillating current LED D in LED D, and this
The more high so LED D of the frequency of oscillation of electric current flicker frequency is also faster in embodiment, and the amplitude of oscillating current is higher, that
LED D maximum brightness it is also higher, such doctor just can by watch LED D come to detect pin 1 output electricity
Stream have adjusted, and also be carried out so after variable resistor R2 and adjustable resistance R6 adjustment is realized by LED D anti-
Feedback, the feedback adjustment output that an open loop closed loop is combined is formed, this makes it possible to the electric current for preferably realizing adjustment detection pin 1
The effect of output so that doctor just can effectively mix up electric current before having an operation, and just can fast and effectively judge during operation
Which bar nerve nerve is specifically, and compared with nerve detecting instrument of the prior art, can preferably be applied to more individuals, drop
The use cost of low survey meter.
