Abstract
The present invention relates to a tape type low-frequency and intermediate-frequency information electrotherapeutic instrument which is a multifunctional medical therapeutic device capable of generating various kinds of information. The information of standard medical current information tape is selectively played. After processing and amplification are carried out, the instrument is used for treatment. The instrument can substitute for various low-frequency and intermediate-frequency electrotherapeutic devices, and can output hundreds of different wave forms. Because of adopting a special magnifying circuits and output circuits, the output wave forms are standard, stable and undistorted, and patients feel no abnormal stimulation feelings when treated. The therapeutic instrument has the advantage of simple operation, and a power supply and an output indication device use a level display composed of light emitting diodes.
Description
Magnetic tape type is low, the intermediate frequency information therapeutic apparatus is a kind of multi-functional, can produce the medical treatment machine of multiple current information.
At present medical low, intermediate frequency therapy apparatus is by power pack, signal generator, amplification and export four parts and form.Because the difference of signal, amplification and output are also different.Therefore, in order to adapt to a certain signal, just must use a kind of machine of special use.So low, intermediate frequency therapy apparatus has to have tens of kinds more than.
Because the needs of conditions of patients, when requiring multiple treatment, just must the replacing machine, berth, even clinic, bring inconvenience.
Use the various information therapy machines of cassette tape, because the restriction of amplification and output circuit can only be used for individual event treatment.
In view of current use low, intermediate frequency therapy apparatus is wide in variety, complex structure, operation inconvenience.The invention provides a kind of low, intermediate frequency information therapeutic apparatus can a tractor serves several purposes, can replace multiple low, intermediate frequency therapy machine.
The invention reside in and to produce multiple signal source,, reach various low, electric current of intermediate frequency information standard, stable, undistorted, effective patient treatment through the amplification and the output circuit of particular design.
The present invention is made up of information source, preamplifier, out amplifier, power supply, power supply and output level display five parts.
Figure one: magnetic tape type is low, intermediate frequency information therapeutic apparatus operation principle block diagram.
Figure two: amplification, output electrical schematic diagram.
Information source is made up of common cassette tape walkman or videocorder.Information is selected the medical current information tape of the standard of prerecording for use.

The medical current information tape of standard be with medical low, the electric current of intermediate frequency of various standards under oscillographic monitoring, it is standby to be recorded on T, D, the K cassette tape storage with the high-fidelity radio cassette player.
Power supply and level show the use light emitting diode.Power supply is shown by green LED, 6 volts of power supplies of direct current.Level shows by one group of red light emitting diodes to be implemented, and adopts two explicit representations.
During demonstration, by in to showing simultaneously to, right both sides.
