Abstract

The utility model discloses a muscle electrical inductive curing apparatus, which comprises a box body; a display screen as well as an injecting needle-shaped guide needle electrode and a reference electrode are arranged on the box body. The injecting needle-shaped guide needle electrode is used for contacting with people; an insulated material is coated on the outer surface of the injecting needle-shaped guide needle electrode. A circuit is arranged inside the box body; the circuit comprises a preamplifier, a filter amplifier, a power amplifier and an A/D conversion device. The fan-in of the preamplifier and the filter amplifier is connected with the fan-in of the A/D conversion device; the fan-out of the A/D conversion device is connected with the display screen. When being used, the guide needle electrode is inserted into the muscle wants to be inspected and cured. The reference electrode is contacted with the skin around; according to the obtained muscle electromyography, the halter muscle can be judged; when the guide needle electrode detects a pathological changed halter muscle, the utility model can implement injecting medicine. The muscle electrical inductive curing apparatus of the utility model has the advantages of simple structure, low cost and intuitionistic operation. Using the curing apparatus, doctor can conveniently confirm the halter muscle and enhance the diagnosing and curing effect.

Description

Myoelectricity guiding therapeutic instrument

Technical field

This utility model relates to a kind of Medical Instruments, is the guiding therapeutic instrument of true accurate spasm target muscle specifically.

Background technology

The botulinum toxin type A local injection is as the first-selected Therapeutic Method of many locality muscle spasm diseases over surplus in the of nearly ten year, and the key of treatment success or not is the target muscle that can medicine accurately inject spasm, the meticulous muscle of part particularly, as eye muscle etc., be positioned at the muscle in deep, as tibialis posterior.At present most hospital is when the injection botulinum toxin type A, it is the target muscle of surveying pathological changes with doctor's sensation, also have under the guiding of large-scale electromyograph(EMG and seek target muscle, injectable drug, but large-scale electromyograph(EMG not only costs an arm and a leg, generally have only large hospital just can buy, and in use, the clinician is difficult to coordinate with electromechanical diagram chamber doctor sometimes.

Summary of the invention

It is lower that the purpose of this utility model provides a kind of cost, simple to operate, directly perceived, easy to carry, is convenient to the doctor and determines that target muscle is to improve the myoelectricity guiding therapeutic instrument of diagnostic and therapeutic effect.

Myoelectricity guiding therapeutic instrument of the present utility model comprises casing, be furnished with display screen and the appearance that is used for contacting on the casing and scribble the entry needle type guide needle electrode and the reference electrode of insulant with human body, be provided with circuit in the casing, that this circuit comprises is preposition, filter amplifier, power amplifier and A/D converter, input preposition, filter amplifier links to each other with reference electrode with the guide needle electrode, outfan links to each other with the input of power amplifier, the outfan of power amplifier links to each other with the input of A/D converter, and the outfan of A/D converter links to each other with display screen.

During work, the guide needle electrode is inserted the muscle of required inspection and treatment, reference electrode contacts with surrounding skin, the muscle action potential signal that guide needle electrode and reference electrode are drawn is through preposition, filter amplifier and power amplifier are defeated by A/D converter after amplifying, become digital signal to be defeated by display screen analog signal conversion by A/D converter, demonstrate the myoelectricity figure at display screen, change the position that the guide needle electrode is planted, the angle and the degree of depth, can obtain different myoelectricity figures, according to gained myoelectricity figure, whether can differentiate is target muscle, when the guide needle electrode detector arrives the target muscle of pathological changes, just filling can there be the syringe of medicine to link to each other injectable drug with injection orifice on the guide needle electrode.

Myoelectricity of the present utility model guiding therapeutic instrument is simple in structure, cost is low, directly perceived, use this therapeutic instrument to be convenient to the doctor and determine target muscle, improve diagnostic and therapeutic effect.

Fig. 3 is a guide needle electrode sketch map.

The specific embodiment

With reference to Fig. 1, Fig. 2, myoelectricity guiding therapeutic instrument of the present utility model comprises casing 1, on case, be furnished withdisplay screen 2, with the entry needle typeguide needle electrode 3 and thereference electrode 4 that are used for contacting with human body,reference electrode 4 is common electro-medical pole piece, the appearance ofguide needle electrode 3 scribbles poly-first fluorothene insulant, the guide needle electrode hasinjection orifice 10, can link to each other with syringe, be convenient transposing guide needle electrode, can make the shell of guide needle electrode havejoint 11 as shown in Figure 3, so that the clip clamping that links to each other with circuit.The intravital circuit of case as shown in Figure 2, it comprises preposition,filter amplifier 5,power amplifier 6 and the A/D converter 7 that links to each other withguide needle electrode 3, reference electrode 4.In the illustrated example, preposition,filter amplifier 5 adopts integrated package SY020308, guideneedle electrode 3 links to each other with the A1 foot of SY020308,reference electrode 4 links to each other with the A10 foot of SY020308, the A8 foot of SY020308 links to each other with the input ofpower amplifier 6, and used power amplifier, A/D converter is known general power amplifier and A/D converter in this utility model.As available LM386 power amplifier, the A/D converter of ICL7106 model.

Usually, can insertspeaker 8 more in addition at the outfan of power amplifier, so that the doctor is except also differentiating the pathological changes target muscle from sound from the myoelectricity figure of display screen.Be used to connect USB interface ofcomputer 9 and insert again, facilitate the use computer the myoelectricity figure is done further to analyze at the outfan of A/D converter.
