Detailed description of the invention

Purpose, technical scheme and advantage for making the application are clearer, below in conjunction with drawings and the specific embodiments, to this Application is described in further detail.

In the following description, quoting of " embodiment ", " embodiment ", " example ", " example " etc. is shown The embodiment so describing or example can include special characteristic, structure, characteristic, character, element or limit, but not each is real Execute example or example all necessarily includes special characteristic, structure, characteristic, character, element or limit.In addition, reuse phrase " according to One embodiment of the application " is although it is possible to refer to identical embodiment, but is not necessarily referring to identical embodiment.

For the sake of simplicity, eliminate in below describing and well known to a person skilled in the art some technical characteristic.

An embodiment according to the application, provides a kind of low pulse physiotherapy instrument, as it is shown in figure 1, include MCU processor, Power amplification circuit, increasing apparatus, piezoelectric driving circuit and control panel；MCU processor is put with waveform recombiner, power respectively Big circuit, increasing apparatus, piezoelectric driving circuit and control panel electrical connection.

MCU processor, is responsible for producing various composite wave-shapes required for physiotherapy equipment output, and basic waveform includes the triangle of symmetry Waveform, sinusoidal wave, square wave and DC component are the trapezoidal wave of zero, and composite wave-shape is then to be generated by above waveform combination, with necessarily Cycle exports.Composite wave-shape comprises continuous wave, density waveform, interrupted waveform.In the present embodiment, MCU processor is 32, master Frequently the processor of 48MHz, built-in 64Kbytes flash memory, 16 port number weighted-voltage D/A converters, 10 groups of timers, DLT is used Input/output port, the PWM waveform of the highest generation 3MHz, therefore apply low frequency K Hz waveform to have at a relatively high accuracy.

Power amplification circuit, for realizing being amplified by analog circuit by the composite wave-shape that MCU produces, MCU produces Composite wave-shape energy small, it is impossible to directly export, it is therefore desirable to through overvoltage, Current amplifier, make this composite signal have one Determining power, virtual value is not more than 10W.Power amplification circuit in the present embodiment includes amplifier, as in figure 2 it is shown, amplifier Reversed-phase output connects the first resistance R1 and one end of the second resistance R2 respectively, and the other end of the first resistance R1 is through the first electric capacity Being grounded after C1, the other end of the second resistance R2 connects the output of amplifier；The in-phase input end of amplifier connects the 3rd respectively Electric capacity C3 and the 4th resistance R4 one end, the 3rd electric capacity C3 other end connects waveform recombiner, and the 4th resistance R4 other end connects the Five resistance R5 one end, the 5th resistance R5 other end connects second electric capacity C2 one end and is simultaneously grounded, and the second electric capacity C2 other end is through the It is connected with power supply after three resistance R3.

Piezoelectric driving circuit, for by MCU generate composite wave-shape be transformed into after power amplification driving electrode work institute Required voltage electric current.In the present embodiment, the circuit diagram of piezoelectric driving circuit is as it is shown on figure 3, its operation principle is: this circuit is defeated The waveform signal entering is the signal after higher level's power amplification circuit amplifies, and the control signal of this circuit is produced by MCU processor Raw, control signal includes signal strength signal intensity control and output waveform control.Select pattern according to user, produce the ripple required for output Shape, after waveform is compound, is carried out boosting by increasing apparatus, is dropped electric current, make the electric current on electrode meet safe current and require.

An embodiment according to the application, the control panel of this low pulse physiotherapy instrument includes operation interface and display circle Face, it is possible to achieve the selection of physiotherapy equipment physiotherapy equipment output level, output waveform, physiotherapy equipment pattern and physiotherapy equipment duty, if Determine the corresponding output function of physiotherapy equipment；This display interface and operation interface can be realized by touch-screen, and user can directly touch Touching and operating on screen, this display interface is alternatively common display screen, and operation interface is button group.

Embodiment described above only represents several embodiments of the present utility model, and it describes more concrete and detailed, but The restriction to the utility model scope can not be interpreted as.It should be pointed out that, for the person of ordinary skill of the art, Without departing from the concept of the premise utility, can also make some deformation and improve, these broadly fall into the utility model Protection domain.Therefore protection domain of the present utility model should be as the criterion with described claim.
