Abstract
The utility model relates to an electric therapeutic instrument utilizing a USB interface of a PC, which comprises an output electrode, an amplifying circuit, etc. The utility model is characterized in that the electric therapeutic instrument also comprises a special integrated circuit used for USB audio processing is connected with the USB interface of the PC, wherein the audio signal output end of the integrated circuit is connected to the signal input end of the amplifying circuit; the output end of the amplifying circuit is connected to the output electrode. Since the utility model directly uses a sheet of the special integrated circuit used for the USB audio processing to complete the treatment of the reducing processing of waveshapes, a sound card device of the original PC does not need to be utilized. The utility model has the advantages of simple circuit structure, plug and play, flexible and convenient use, and convenient carrying.
Description
Technical field the present invention relates to the medium and low frequency electric therapeutic instrument in a kind of medical health apparatus field, also relates to a kind of peripheral hardware accessory of PC micro computer simultaneously.
Background technology medium and low frequency electric therapeutic instrument (promptly comprises mid-frequency treatment device and low-frequency therapy apparatus, comprise that also simulation massage device and some adopt the weight reducing apparatus of electric pulse stimulation, its principle is the same), it is a kind of electronic installation that is used for health care, principle is by the synthetic medium and low frequency impulse wave that produces of electronic circuit, through amplification output to be installed in by the electrode of therapist health on, by with electric pulse the stimulation of human body being reached treatment and health effect, its treatment and health effect and scope depend on the variation of medium and low frequency impulse wave waveform.
Chinese invention patent application " production method of electric therapeutic instrument treatment signal and use the electrotherapeutic apparatus of this method " (application number: 031350151) disclose a kind of new working method of medium and low frequency electric therapeutic instrument, this working method will be treated waveform and be propagated and reduce processings as a kind of audio signal, make the application of therapeutic instrument more powerful and make things convenient for.Such as this working method is applied on the micro computer PC, can restore the treatment signal by sound card equipment, obtain abundant multiple electrotherapy waveform, but by the disclosed technology of this application, obviously need to use the sound card equipment of PC,, just can't realize for the PC of originally not adorning sound card.
Summary of the invention purpose of the present invention is to disclose a kind of electric therapeutic instrument that cooperates PC work and do not need to use the PC sound card.
The object of the present invention is achieved like this: it includes output electrode, amplifying circuit etc., it is characterized in that this electric therapeutic instrument also comprises a USB Audio Processing special IC that can be connected with the PC USB interface, the audio signal output end of this integrated circuit, be connected to the signal input part of amplifying circuit, the outfan of amplifying circuit is connected to output electrode.
The reduction that the present invention takes directly to use a slice USB Audio Processing special IC to finish the treatment waveform is handled, so do not need to utilize the sound card equipment of original PC, and circuit structure is simple, plug and play, use more convenient flexibly, be convenient to especially portably use.
Description of drawings Fig. 1 is the circuit theory diagrams of one embodiment of the invention.
With reference to the accompanying drawings embodiments of the invention are described below the specific embodiment.
Among Fig. 1, IC1 is the Audio Processing integrated circuit PCM2900 of a slice USB interface special use, be widely used in and make the USB sound card, peripheral circuit that it is detailed and data can be with reference to " electronics newspaper " the 22nd phases in 2004, or download the website of landing manufacturer's texas,U.S electric corporation (TI), the connection of only drawing the major function pin among the figure, positive and negative foot the 3rd foot of power supply wherein, the 4th foot, with data foot the 1st foot, the 2nd foot, be connected with PC by USB interface and carry out data communication, the 15th foot, the 16th foot is the binaural audio signal (only getting a tunnel here) of output pin output demodulation, the voltage signal of its output, that is to say the treatment waveshape signal, after carrying out filtering and amplify through IC2, deliver to " amplifying circuit " formed by IC3 and carry out voltage amplification, " amplifying circuit " can adopt the various amplifying circuits of existing electric therapeutic instrument technology, but contact with the direct of human body in order to isolate PC, present embodiment has output isolation transformer B, uses safer.The electrotherapy signal of output outputs to " output electrode " after " amplifying circuit " amplifies, and realizes the purpose that human body is treated or massaged.
Because IC1 self is solidified with the driver of USB interface, after this device connected the USB interface of PC, the WINDOWS operating system of PC identification automatically also installed driver automatically, finishes " plug and play " of this device on PC.The producing method of this device treatment signal, be according to Chinese invention patent application " electric therapeutic instrument is treated the production method of signal and used the electrotherapeutic apparatus of this method " (application number: 031350151) disclosed technology, promptly treat waveform and be used as audio signal, record the file that becomes a kind of audio format, be stored on the storage unit such as hard disk of PC, during use, the operator starts a playout software space of a whole page, the file of choosing the corresponding treatment waveform in the inside, wave file storehouse is play as required, and data are outputed to USB interface, ICI by this device restores the treatment waveshape signal, outputs to electrode after amplifying through IC3 and realizes therapeutic purposes.As for playout software, the user can directly adopt the original audio frequency playout software of PC, and the Windows Media Player such as Microsoft perhaps works out a playout software voluntarily with language such as VB, VC.
This device is owing to use USB special audio process chip, so can directly be connected and finish the reduction output of treatment waveform with the PC USB interface, no longer need the sound card equipment on the PC, so the scope of application is more extensive, and the power supply that can directly use USB interface to provide, for uses such as IC1, IC2, IC3, so self can no longer need built-in power, can alleviate its volume and weight greatly, carry and use more convenient.
IC1 of the present invention adopts the USB Audio Processing chip of a slice texas,U.S electric corporation, can certainly adopt the identical chip of other functions, CM102A/S chip as Taiwan China news electronic enterprise limited company, UDA1321PS of Philips Philips company or the like, though its peripheral circuit is slightly different, but the circuit structures such as output of its function and USB interface, audio signal all are the same, no longer describe here.
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.
