The present invention is stored in PC with digitized treatment Wave data, pass through working procedure during use, the Wave data of PC the inside is sent to this device, behind D/A switch, directly restore original treatment waveshape signal, simply say so treatment waveform " broadcast " is come out, by the different treatment Wave data file of procedure Selection, just can go out different treatment waveshape signals in this device reduction " broadcast ", so the user can own select by program on PC and upgrade different treatment waveforms, also can exchange and download various treatment waveforms by disk or network, use more flexible extensively, the scope of application is wider.The present invention can also also be a treatment prescription with the various treatment waveshape signals of other electric therapeutic instrument, by being stored on the PC after the conversion of this device, realizes learning functionality, and technology is more progressive, uses more flexible.And the present invention directly uses the digital communication interface of PC, need not take the sound card of PC, can not influence the normal use of PC.
Description of drawings
Fig. 1 is the circuit block diagram of one embodiment of the invention.
Fig. 2 is the circuit block diagram of another embodiment of the present invention.
The specific embodiment
With reference to the accompanying drawings embodiments of the invention are described below.
Among Fig. 1, the data communication interface JP1 of present embodiment adopts USB interface, can be connected with the USB socket of PC by the USB connecting line, the special-purpose USB microprocessor of the CY7C64613 that " microprocessor " in the block diagram and " interface circuit " can adopt a slice Cypress company to produce is finished, this chip includes the USB transceiver, the serial interface engine, with enhanced edition 8051 processors, can directly use 8051 instruction, can finish with the usb function between the PC, also can finish the various control functions in this device.The USBD+ of microprocessor CY7C64613 and USBD-are connected respectively to D+ and the D-lead end in the USB socket (JP1), " D/A switch " circuit can adopt 8 figure places/analog conversion circuit DAC0800, its digital input end, be connected to the PA0-PA7 of CY7C64613, the simulation of DAC0800 is output as current mode output, can be converted to voltage output through the OP amplifier, the voltage signal of its output, that is to say the treatment waveshape signal through after the filtering, be connected to " amplifying circuit " and carry out outputing to after the voltage amplification " output electrode ", realize the purpose that human body is treated or massaged.Amplifying circuit can adopt the various amplifying circuits of existing electric therapeutic instrument technology, but contacts with the direct of human body in order to isolate the PC that belongs to an electric appliances, preferably adopts output isolation transformer, uses safer.
USB socket JP1 is inserted on the USB socket of PC in use, the driver that cooperates USB interface to use is housed on the PC, with the application program that cooperates this apparatus function, the function of application program is to start a software operation space of a whole page, operation according to user, choose corresponding treatment waveform data file in Wave data library the inside, and data are outputed to USB interface, concrete program can be used establishments such as C language, be similar to the program of USB audio player, belong to the ordinary skill that the professional of software field can finish, do not do introduction here.
Obviously, the treatment waveform and the circuit of the present invention's output are irrelevant, even it is also irrelevant with concrete program structure, the Wave data file that the program that depends primarily on is play, by the different treatment Wave data file of procedure Selection, just can go out different treatment waveshape signals in this device reduction " broadcast ", so the user can own select by software on PC and upgrade different treatment waveforms, or exchange by disk or network and to download various treatment waveforms, use more flexible extensively, the scope of application is wider.And the present invention directly uses the digital communication interface of PC, need not take the sound card of PC, can not influence the normal use of PC.
Fig. 2 is the circuit block diagram of another embodiment of the present invention.This embodiment is on the basis of Fig. 1 first embodiment, increase a functional select switch K, an attenuator circuit and a mould/number conversion circuit, when selecting switch to place therapeutic state, circuit carries out work by the described circuit structure of first embodiment, when selecting switch to place learning state, output electrode is as the input equipment of waveshape signal, can be connected with the outfan of other electric therapeutic instrument, the output waveform signals of other electric therapeutic instrument is imported by output electrode, and decay through attenuator circuit and to be connected to the analog input end of mould/number conversion circuit after the blood pressure lowering, attenuator circuit can adopt simple resistance drop volt circuit, mould/number conversion circuit can adopt ADC0804, under the control of CY7C64613, the analog waveform signal of input is converted to digital signal, again by the output of its digital output end,, promptly be connected respectively to D+ and D-lead end in the USB socket (JP1) by USBD+ and USBD-equally by the data terminal that is operatively connected to interface circuit of CY7C64613.
Like this, under learning state, under the control of CY7C64613 and program, by the waveshape signal of electrode input, after decay blood pressure lowering and mould/number conversion, be transported to PC by USB interface, by PC digitized Wave data is write down storage, as treatment Wave data file.When needing later on, under therapeutic state, this treatment Wave data file can be read and be transported to this electric therapeutic instrument again, be reduced to original treatment waveshape signal again and export treatment, realize the function of study, use more flexible.
Medium and low frequency treatment waveshape signal of the present invention, be meant that a class is by the synthetic medium and low frequency oscillator signal of certain or certain group dedicated pulse shape, the medium and low frequency oscillator signal of the one group of multiple waveform modulated that combines such as square wave, triangular wave, sawtooth waveforms modulation or by them, it can be used as specific prescription, produce certain specific therapeutic effect, or produce certain specific simulation massaging action.It is different from common music signal, and the waveform of music signal is irregular, and stimulating the sense of motion that human body produced is disorderly and unsystematic or even twinge, can't also can't produce particular treatment effect and massaging action as specific prescription.
The production method of these treatment waveforms, can be directly to adopt learning functionality of the present invention to learn to obtain by the user, also can be to adopt similar method to produce and write down storage, adopt the mode of software to propagate into the user then with product or service by producer.The form of Wave data file, can determine according to program, and propagate with helping for general, preferably adopt and the same form of audio file, as WAV, MP3 etc., microprocessor at this moment of the present invention, D/A switch circuit and mould/number conversion circuit will adopt should be able to carry out the chip that audio format is handled mutually.
Medically low frequency is defined as below the 1KHz, intermediate frequency is defined as 1KHz-100KHz, the present invention is because the restriction of sampling frequency generally can only be handled tens KHz following low frequency and part intermediate-freuqncy signal.
Though the present invention is as a kind of medium and low frequency electric therapeutic instrument, but utilize technology of the present invention, can also be used for the generation of the simulated action of PC, because the pulse-modulated signal that some is specific acts on the human muscle by electrode, can make human body produce certain specific sense of motion, also promptly produce simulated action, so modulation produces the pulse modulated wave of various different frequencies and waveform, just can obtain various simulated action, its operation principle is the same with low frequency simulation massage device in fact.
