Description

The nerve trunk positioner

Technical field

The present invention relates to a kind of armarium, particularly a kind of location intramuscular injection point nerve trunk positioners such as muscle spasm that the human body myodystonia causes, apoplexy of diagnosing.

Background technology

Rehabilitation medicine has become one of medical science applied important component part.At present, the allomeric function recovery of rehabilitation and the unique effect of reconstruction more and more are subjected to medical circle and the sick and wounded and crippled's attention, and wherein neural dissolving technology and chemical nerve block technology are used in human muscle's dyskinesia gradually widely.And the method for this treatment and technology are that mainly accurately the location causes dystonic motor point and nerve trunk.It is with sensation and experience location intramuscular injection point when implementing treatment that many hospital doctors are arranged at present, have plenty of and under the guiding of electromyograph(EMG, inject, but very big shortcoming and limitation are arranged: manually locate inaccuracy, also be easy to generate side effect, effect and efficient are undesirable.Large-scale electromyograph(EMG is highly professional, and the operation relative complex costs an arm and a leg.

Summary of the invention

The technical problem to be solved in the present invention is at the deficiencies in the prior art, has proposed a kind of nerve trunk positioner directly perceived, as to make things convenient for diagnosis and treatment location, raising therapeutic effect of operating.

The technical problem to be solved in the present invention is achieved through the following technical solutions, a kind of nerve trunk positioner, be characterized in: it is provided with detecting electrode and main control chip, detecting electrode joins by boost amplifying circuit and Waveform generating circuit, Waveform generating circuit inserts main control chip, main control chip also joins with power control circuit, keyboard input circuit respectively, main control chip is connected with display by output interface, the signal waveform of detecting electrode output is a square wave, and the wide 0.05～5ms of being of ripple, frequency are that 0.5～3Hz, electric current are 0.1～30mA.

The technical problem to be solved in the present invention can also come to realize that further described detecting electrode comprises autohension electrode slice, diagnosing and treating pen and electrode needle by the following technical programs.

The technical problem to be solved in the present invention can also come by the following technical programs further to realize that main control chip joins with outage and incoming call instantaneous peak current suppressor.

The technical problem to be solved in the present invention can also come to realize that further main control chip is connected with buzzer and indicator light circuit by the following technical programs.

The present invention is a kind of simple nerve trunk positioner.The contraction of muscle is controlled by nerve.Give the certain electricity irritation of nervus motorius, muscle can produce the contraction of rhythmicity with the frequency that stimulates.According to above-mentioned mechanism, low-frequency electrical stimulation pulse is because stimulus frequency is low, so only can cause that straight line distributes and be that less nervus motorius produces and stimulates.In addition, because neural control causes the frequency of muscle contraction to conform to, and has utilization to observe, (0.5～3Hz) produces single line nervus motorius stimulation conduction therefore to select lower frequency.Body surface as muscle is surveyed.Be applicable to the neural location of muscle control of measuring the skin below.Be used for the shallow-layer muscle group.In addition, utilize the needle electrode location, this needle electrode is the pin insulation, its needle point conduction.Its principle is to utilize probe to insert the nerve of the muscle measurement muscle and deep under the skin.Because the very little and vitro skin resistance difference of the intravital resistance of people is bigger, so design current is in that (0.1～30mA) is adjustable continuously, to adapt to the needs that the inside and outside is surveyed.Along with the change of stimulus intensity is big, the intensity of its contraction and sensation are also obvious more.Control widely at the pulse wave-wave be (0.05～5ms), the rhythmic contraction of certain amplitude, thereby very clearly find out the motor point and the nerve trunk of muscle, effectively overcome the drawback that artificial location and large-scale electromyograph(EMG are located muscle.And cost is low, and is easy and simple to handle.

The specific embodiment

Instrument of the present invention comprises main frame, and display lamp 13 is arranged on the main frame 10, display 1, buzzer 14.Interface 12 is provided, can with professional electrode needle 16, autohension electrode slice 15, diagnosing and treating pen 17 phases that link to each other.Main frame 10 inside are provided with circuit, circuit comprises that main control chip 9, Waveform generating circuit 3, power control circuit 7, keyboard input circuit 8 join, main control chip 9 is connected with display 1 by output interface 18, the signal waveform of detecting electrode output is a square wave, and the wide 0.05～5ms of being of ripple, frequency are that 0.5～3Hz, electric current are 0.1～30mA.Specialty electrode needle 16, autohension electrode slice 15, diagnosing and treating pen 17 links to each other with the amplifying circuit 4 that boosts, and the amplifying circuit 4 that boosts links to each other with Waveform generating circuit 3, and Waveform generating circuit 3 links to each other with main control chip 9, and display 1, buzzer 14 link to each other with governor circuit.

During use, autohension electrode slice 15 is attached to the relevant position of human body, surveys the muscle position that needs treatment with diagnosing and treating pen 17, main frame produces certain frequency and amplitude pulses ripple stimulated muscle, muscle is produced shrink, and finds out the motor point according to the situation of muscle contraction.Reuse electrode special pin 16 pierces through muscle motor points, finds out nerve trunk and implements injection for curing.

Core of the present invention is a single chip microcomputer.Adopt single chip computer AT MEGA8, volume is little, and power consumption is few.Controlled frequency, pulse width and output intensity, built-in D/A-A/D and crystal oscillating circuit, reliable and stable.Directly drive the LCD liquid crystal display, display adopts Chinese dot matrix LCD 64*128 pixel, simple and direct-viewing operation.Power circuit: adopt DC-DC module efficiently, can satisfy the use of disposable battery 4.5V and chargeable battery 3.6V.Simultaneously can the external AC source adapter.Keyboard circuit adopts the PVC thin film switch, and the life-span is long, advantages such as good stability.

Frequency generating circuit adopts 4066.The power amplifier and the part of boosting, the present invention uses LM358 low power operational amplifier and the transistor T IP31C amplifier section as electric current.Directly connect booster transformer, as the modulated current of output.Aspect software, designed power supply and recovered and interrupted the inhibition of instantaneous large-current suddenly.Life safety when guaranteeing because of external voltage and the generation of other faults.In addition, software provides resetting fast of electric current and stepping gear, convenient clinical use.Advantage of the present invention is: simple, intuitive, cost is low.And unexpected outage and incoming call have been taked effectively and the instantaneous large-current that produces.
