Abstract

Magnetic tape type is low, intermediate frequency information electric therapeutic instrument is a kind of multi-functional, can produce the medical treatment machine of multiple information.It is the information that " the medical current information tape of standard " put in choosing, and is treated, a kind of instrument for the treatment of after the amplification.Multiple low, intermediate frequency therapy apparatus can be replaced, hundreds of different wave modes can be exported.Because of selecting special-purpose amplification for use, output circuit makes wave mode outputting standard, stable, undistorted, treats no abnormal sensation.This therapeutic instrument is easy and simple to handle, the lever indicator that power supply and output indication adopt light emitting diode to form.

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.
Fig. 1: magnetic tape type is low, intermediate frequency information therapeutic apparatus operation principle block diagram.
Fig. 2: amplification, output electrical schematic diagram.
Information source is made up of common cassette tape walkman or videocorder. Information is selected and is given the medical current information tape of the standard that records earlier.
The current information of walkman (or videocorder) output is through inductance L, capacitor C1The LC filter circuit that forms enters operational amplifier IC1、IC 2, amplify by the current information of this preamplifier with output.
The current information that amplifies is input to output amplifier again. This output amplifier adopts the E class to amplify OCL output. In the employing, large power triode, by positive and negative 80 volts of power supplies.
In order to prevent that high frequency from sealing in, interference standard electro-medical stream information, in the preamplifier addition by inductance L, capacitor C 1Form the LC filter circuit.
In order to make this instrument performance stable, keep the output balance, reduce the influence that output circuit is subjected to variation of ambient temperature, in output amplifier, middle pliotron BG 1, BG 2, BG 7, BG 8Base stage over the ground between addition thermistor element.By critesistor R 10, R 11, R 29, R 30Play temperature compensation function.
In power supply and output circuit, be provided with lever indicator, can understand the work and the output situation of instrument by lever indicator.
Embodiment:
Common boxlike walkman or videocorder are adopted in information source, by 6 volts of power supplies of direct current.The outfan of walkman is connected to by inductance L and capacitor C 1The LC filter input end of forming.Preamplifier is made up of 2 operational amplifiers 741 or F007 and other components and parts.IC 1, IC 2Respectively by positive and negative 15 volts of power supplies.
Out amplifier is respectively by the 4 power tube BG that merely hit 1, BG 2, BG 7, BG 8And 4 high power valve BG 3, BG 4, BG 5, BG 6Form, by positive and negative 80 volts of power supplies.By BG 1~BG 8Totally 8 merely hit, high power valve and other components and parts form the E class and amplify the OCL output circuit.
In order to make instrument performance stable, reduce the influence that output circuit is subjected to variation of ambient temperature, reach compensating action, BG 1, BG 2, BG 7, BG 8Base stage resistance to earth R 10, R 11, R 29, R 30Select critesistor 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, show simultaneously to left and right both sides by the centre.
