Abstract

The utility model relates to a portable electric stimulating physiotherapy equipment, comprising a control circuit and a stimulating electrode, wherein an output end of the control circuit is communicated with the stimulating electrode of which the key is that being arranged a plurality of stimulating electrodes. One transformer output end of the control circuit is connected with every stimulating electrode via photoconductive resistances. Each of photoconductive resistance correspondingly has a luminescent diode which is luminously or non-luminously controlled by a single-chip. The other output of the transformer is connected with a common electrode. The utility model has the advantages of simple structure, minor volume and little power consumption.

Description

Portable electricity irritation physiotherapy table

Technical field

This utility model relates to a kind of portable electricity irritation physiotherapy table.

Background technology

Known portable electricity irritation physiotherapy table generally has only 1～2 tunnel output at present, and stimulation point is few.The electricity irritation physiotherapy table that multichannel output is also arranged generally is the corresponding transformator of each road output, its circuit structure complexity, thus make less that the volume of physiotherapy table can not do, and power consumption is big.

Technology contents

Problem to be solved in the utility model provides the portable electricity irritation physiotherapy table that a kind of circuit structure is simple, volume is less and power consumption is less.

The technical scheme that this utility model provides is a kind of portable electricity irritation physiotherapy table, comprise control circuit and stimulating electrode, the outfan of control circuit connects with stimulating electrode, its key is to be provided with a plurality of stimulating electrodes, one outfan of the transformator of control circuit links to each other with each stimulating electrode by photoconductive resistance respectively, all to having one by its luminous or non-luminous light emitting diode of Single-chip Controlling, another outfan of transformator links to each other with public electrode in each photoconductive resistance.

Above-mentioned stimulating electrode is made up of conducting resinl and Magnet, and Magnet is wrapped in the conducting resinl.

This utility model also can be provided with the attachment that links to each other with stimulating electrode, and attachment is by the rubber sheet that contains iron powder and cover cotton on the rubber sheet that contains iron powder and weave cotton cloth and form.

This utility model is owing to adopt said structure, and by Single-chip Controlling lumination of light emitting diode or not luminous, the resistance of corresponding photoconductive resistance reduces to very little when lumination of light emitting diode, is equivalent to this road and connects and the generation electricity irritation; Corresponding this road is disconnected and is not produced electricity irritation when light emitting diode is not luminous.Need only can provide walking about of multichannel output and electricity irritation by a transformator like this.Thereby this utility model is simple in structure, volume is less and power consumption is little.

Description of drawings

Fig. 1 is an electrical block diagram of the present utility model;

Fig. 2 is the structural representation of this utility model stimulating electrode and attachment.

The specific embodiment

Referring to Fig. 1, Fig. 2, this utility model comprises control circuit and stimulating electrode, the outfan of control circuit connects with electrode, this utility model is provided with 8 stimulating electrode J1～J8, a tap of the high pressure output of the transformator of control circuit is respectively by photoconductive resistance (RG1～RG8) link to each other with each stimulating electrode, each photoconductive resistance is all to having one by its luminous or non-luminous LED 1～LED8 of Single-chip Controlling, light emitting diode is controlled by current-limiting resistance R1～R8 by the PA0～PA7 foot of single-chip microcomputer that it is luminous or not luminous, and another tap of the high pressure output of transformator links to each other with public electrode J9.Single-chip microcomputer IC1 is AT90S4414, also can use AT90S8515, or other I/O mouth that includes EEPROM and 8 direct driving LED of energy are arranged.Button K1～K5 is used to be provided with frequency, pulse width, the timing of electrical stimulation signal, the move mode and the translational speed of stimulus signal, simultaneously also can with button select to have had in the single-chip microcomputer at the set prescription of certain disease.The running parameter that sets can be kept among the EEPROM of single-chip microcomputer, and its running parameter was exactly the parameter of preserving when next time, physical therapy was carried out in start.Liquid crystal display

LCD is used to show the frequency of electrical stimulation signal and pulse width, timing.The multiple move mode of electricity irritation is kept in the single-chip microcomputer, can access as required, and the translational speed of stimulus signal is by the keyboard setting, and move mode and translational speed are shown by LED 1～LED8.The low tension stimulus signal is by the PCO foot output of single-chip microcomputer IC1 (AT90S4414), the base stage of the current drives audion Q1 that signal is transported to after R9, RW1, R10 dividing potential drop.Regulator potentiometer RW1 can change intensity of electric stimulus, i.e. the size of stimulating current, and the range of accommodation of stimulating current is between 0.5～20mA.The colelctor electrode of audion Q1 is connected with a tap of the low pressure winding of output transformer B1, and another tap of B1 is connected with the 6V positive source.

On and off switch K is by the potentiometer RW1 interlock of belt switch, and the existing power supply that prevents of diode D1, D2 connects the effect that damages circuit on the contrary, and the effect of blood pressure lowering is arranged again.The running voltage of single chip computer AT 90S4414 is 2.6～6V, and the highest 7V that may reach of the voltage of the new battery of 6V, two voltage drops of diode in series when energising have so just guaranteed that the running voltage of single-chip microcomputer can not surpass 6V more than 1.1V.

9 foot socket and plugs are adopted in the connection of control circuit of the present utility model and stimulating electrode J1～J9, are convenient to user and connect and dismounting.

Above-mentioned stimulating electrode 5 (referring to Fig. 2) is made up of conducting resinl 1 and Magnet 2, and Magnet 2 is wrapped in the conducting resinl 1.

This utility model also is provided with the attachment that links to each other with stimulating electrode, and attachment is by the rubber sheet 3 that contains iron powder and cover cotton on the rubber sheet 3 that contains iron powder and weave cotton cloth and 4 form.Stimulating electrode can be placed on any position of attachment, during use the attachment that is placed with stimulating electrode is wrapped in the position of somagenic need.

Can preserve the prescription at numerous disease in the single-chip microcomputer, doctor or patient can access use according to the state of an illness, and doctor or patient also can be provided with stimulus frequency voluntarily according to the state of an illness, select move mode and translational speed, are saved in the single-chip microcomputer.
