Description
Technical field
The present invention relates to medicine equipment, and in particular to using the Wound treatment apparatus of phase difference technology.
Background technology
Ultrasonic cleaning is the cavitation effect and vibration at high speed and shearing effect produced in a liquid using ultrasonic wave come clear
Wash wound, this " brushless cleaning " is mainly characterized by that speed is fast, effect is good, easy realization is to the labyrinth wound such as concave-convex type
Deep layer cleaning is carried out, there is the effect of high-efficiency washing to the bacterium at gap, so as to reduce the number of bacteria and species of wound, is dropped
Low infection rate, reduces complication, has wide practical use in Medical wound-cleaning field.
But existing ultrasonic debridement instrument controls inconvenience for ultrasonic frequency, so as to result in clinical debridement effect reduction.
The content of the invention
The technical problems to be solved by the invention are that existing ultrasonic debridement instrument controls inconvenience for ultrasonic frequency, from
And result in clinical debridement effect reduction, it is therefore intended that the Wound treatment apparatus using phase difference technology is provided, solved the above problems.
The present invention is achieved through the following technical solutions：
Using the Wound treatment apparatus of phase difference technology, including：AC modules for providing alternating current；It is whole for switching
The drive module of system；Ultrasonic transducer for converting electrical energy into ultrasonic wave；For providing spy for ultrasonic transducer
Determine the matching module of power；For the sampling module sampled to the electric current on ultrasonic transducer；After to sampling
Electric current is amplified the amplification filtration module of filtering；Carried out for filtered electric current will to be amplified at the phase difference of phase difference processing
Manage module；The DSP module that electric current after for handling phase difference is analyzed；Result after for being analyzed according to DSP module
Produce the DDS module of excitation waveform.
In the prior art, ultrasonic debridement instrument controls inconvenience for ultrasonic frequency, so as to result in clinical debridement effect reduction.
When the present invention is applied, AC modules provide alternating current；Drive module switchs whole system；Ultrasonic transducer converts electrical energy into super
Sound wave；Matching module provides certain power for ultrasonic transducer；Sampling module is adopted to the electric current on ultrasonic transducer
Sample；Amplification filtration module is amplified filtering to the electric current after sampling；Phase difference processing module is entered filtered electric current is amplified
Line phase difference processing；DSP module is analyzed the electric current after phase difference processing；DDS module analyzed according to DSP module after knot
Fruit produces excitation waveform.Because the ac frequency that AC modules are provided can not often be directly applied for ultrasonic transducer, so
Sampling module is sent to DSP module to the current sample on transducer, and after being handled through phase difference, after DSP module is to use
Amperometry simultaneously adjusts waveform parameter, then transfers to DDS module to produce excitation waveform, so as to enter to the waveform being input on transducer
Row circular treatment, until transducer requirement is met, it is achieved thereby that to the convenient control of ultrasonic frequency, improving debridement effect
Really.
Further, the phase difference processing of the phase difference module includes extracting phase difference direction and the phase of sample circuit
Difference value.
Further, the DSP module carries out analysis to the electric current after phase difference processing includes being directed to ultrasonic transducer
Amplitude and frequency are adjusted to electric current.
Further, the excitation waveform that the DDS module is produced uses sine wave.
Further, the DDS module uses AD9833.
The present invention compared with prior art, has the following advantages and advantages：
The present invention is carried out at circulation using the Wound treatment apparatus of phase difference technology to the waveform being input on transducer
Reason, until transducer requirement is met, it is achieved thereby that to the convenient control of ultrasonic frequency, improving clinical debridement effect.
