Description
Technical field
The present invention relates to a kind of EMG detection electrode module.
Background technology
Electromyogram (electromyography) (English abbreviation EMG), applied electronics instrument record muscle is static or electrical activity when shrinking, and electrical stimulation check neural, muscle excited and the method for conduction function.
The functional status that may determine that peripheral nerve, neuron, neuromuscular junction and muscle itself is checked by this.
By measuring the time limit of motor unit potential, wave amplitude, with or without spontaneous electrical activity in quiet situation, and the wave mode shunk energetically of muscle and wave amplitude, neurogenic urinary incontinence and Myopathic lesion can be distinguished, the diagnosis acute and chronic infringement of ventricornu (such as anterior poliomyelitis, motor neuron disease), nerve root and peripheral neuropathy (such as electromyography can assist to determine the position of nerve injury, degree, scope and prognosis). Additionally the change of Neural entrapment sexually transmitted disease (STD), neuritis, heredity dysbolismus neuropathy, various myonosus also there is diagnostic value. Additionally, electromyogram is additionally operable to follow the trail of recovery process and the curative effect of disease in the therapeutic process of various diseases.
Utilize computer technology, Electromyographic automatically analyzing can be made, as resolved electromyogram, single fiber EMG and huge electromyogram etc., improve the positive rate of diagnosis.
The multiplex needle electrode of electromyography and electrical stimulation technology, have certain misery and damage in checking process.
Presently used electromyogram electrode mostly is needle electrode, but the form of existing needle electrode is wire front end is directly connected to electrode, wire is exposed outside, and in detection process, the storage of wire is inconvenient for, and can cause the misery of patient after imprudence touches wire with moving electrode. Further, since the length of the muscle of diverse location is different, therefore the accuracy of positioning of electrode be there is also higher requirement.
Summary of the invention
It is an object of the invention to provide a kind of electromyogram electrode, to solve the problems referred to above.
Present invention employs following technical scheme:
A kind of EMG detection electrode module, it is characterised in that including: electrode installation unit; Electrode tip, is arranged on electrode installation unit; Telescoping tube, is connected with electrode installation unit, has the cavity holding wire inside telescoping tube; Lead wire unit, is connected with telescoping tube, and the wire within telescoping tube is drawn lead wire unit; Wherein, telescoping tube can extend and shorten, and bends to multiple directions.
Further, the EMG detection electrode module of the present invention, can also have a feature in that wherein, electrode tip has electrode tip body and is arranged on the installation button of electrode tip body upper end, electrode installation unit has electrode installation cavity, electrode installation cavity has the body installation cavity being connected and installs button installation cavity, respectively with electrode tip body and the mating shapes installing button.
Further, the EMG detection electrode module of the present invention, it is also possible to having a feature in that wherein, the upper end of electrode tip body has magnetic metallic layers, electrode installation cavity corresponding thereto has Magnet layer.
Further, the EMG detection electrode module of the present invention, it is also possible to having a feature in that wherein, the bottom of body installation cavity has card article, and card article blocks electrode tip body.
Further, the EMG detection electrode module of the present invention, it is also possible to have a feature in that wherein, the bottom of body installation cavity has electrode ports, and the electrode that electrode tip body stretches out stretches out from electrode ports.
The beneficial effect of the invention
The EMG detection electrode module of the present invention, owing to having telescoping tube, wire passes through in telescoping tube, and therefore wire will not be at random surroundings thereof, improves safety.
Further, since have telescoping tube, therefore after determining the position of muscle, it is easier to adjust electrode spacing so that the location of electrode becomes more convenient.
Further, since have electrode installation unit, therefore, it is possible to convenient installation and take off electrode, improve service efficiency.
Accompanying drawing explanation
Fig. 1 is the structural representation of the EMG detection electrode module of the present invention;
Fig. 2 is the explosive view of the EMG detection electrode module of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
As depicted in figs. 1 and 2, EMG detection electrode module includes: two electrode installation units 11, two electrode tips 12, two telescoping tubes 13 and lead wire unit 14.
Electrode tip 12, is arranged in the electrode installation cavity of electrode installation unit 11, and electrode tip 12 has electrode tip body 121 and is arranged on the installation button 122 of electrode tip body upper end.
Electrode installation unit 11, has electrode installation cavity, and electrode installation cavity has the body installation cavity 111 being connected and installs button installation cavity 112, respectively with electrode tip body 121 and the mating shapes installing button 122. Button 122 is installed there is thin cervical region so that button 122 is installed and can be stuck in installation button installation cavity 112. Button 122 slip Ka Chu from the side is installed and installs in button installation cavity 112, when installing and take off electrode tip quickly, conveniently, simultaneously in the process that electrode normally uses, difficult drop-off.
Telescoping tube 13, is connected with electrode installation unit 11, and telescoping tube 13 is internal has the cavity holding wire; Wire is connected with the contact point installed within button installation cavity 112. Telescoping tube 13 can extend and shorten, and bends to multiple directions. Telescoping tube has multistage pleated sheet constitute, every one-level is able to maintain that in current state after pulling open and folding, therefore in use, after telescoping tube is stretched to certain length, its length is secured to current location, therefore still can maintain corresponding length at first use telescoping tube, provide convenience for using next time. Further, owing to telescoping tube is four prism type, therefore it can vertically and horizontally, or combinations of directions up and down rotates and maintains correspondingly flexed state, and needing to be fixed on particular curve angle for electrode provides facility.
Lead wire unit 14, is connected with telescoping tube 13, and the wire within telescoping tube 13 is drawn from the fairlead 15 lead wire unit 11.
The upper end of electrode tip body 121 has magnetic metallic layers 123, and electrode installation cavity corresponding thereto has Magnet layer. After electrode tip snaps in electrode installation unit 11, magnetic metallic layers 123 is attracted by Magnet layer so that electrode tip is installed more firm.
The bottom of body installation cavity has card article 113, and card article 113 blocks electrode tip body 121.
The bottom of body installation cavity has electrode ports 114, and the electrode 124 that electrode tip body 121 stretches out stretches out from electrode ports 114.
