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
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.
Description of drawings
Fig. 1 is this utility model outline drawing;
