Embodiment 1

[0036] This embodiment is an embodiment of the automatic tuning method of the ultrashort wave electrotherapy instrument of the present invention, and its specific scheme is to detect the total power of the ultrashort wave electrotherapy instrument, obtain the radio frequency output power by subtracting the power consumption of the ultrashort wave electrotherapy instrument itself from the total power, and control the step The motor rotates the tuning capacitor, and when the RF output power is at its maximum, the stepping motor stops rotating. In the automatic tuning method of the present invention, a standard analog load is used to detect the actual radio frequency output power, so as to correct the calculated radio frequency output power. Make the calculation of output power more accurate.

Embodiment 2

[0038] This embodiment is a specific embodiment of the ultrashort wave electrotherapy apparatus of the present invention. figure 1 It is a structural block diagram of the invented ultrashort wave electrotherapy instrument. Such as figure 1 As shown, the ultrashort wave electrotherapy instrument includes:

[0039] The power supply circuit provides electric energy for the electrotherapy apparatus;

[0040] A high-frequency oscillation power amplifier circuit, including an input loop and an output loop with a tuning capacitor, outputs radio frequency;

[0041] The oscillation control circuit controls the voltage of the input circuit that the power supply circuit outputs to the high-frequency oscillation power amplifier circuit according to the instructions of the main control computer, so as to obtain the required output power;

[0042] Stepping motor, rotating the tuning capacitor to adjust the output power;

[0043] The motor control circuit drives the stepper motor to rota...

Abstract

The invention discloses an ultrashort wave electrotherapy device and an automatic tuning method thereof. The automatic tuning method of the ultrashort wave electrotherapy device is characterized in that: detecting total power of the ultrashort wave electrotherapy device, obtaining radio frequency output power through subtracting consumption power of the ultrashort wave electrotherapy device from the total power, and controlling a stepping motor to rotate a tuning capacitor, wherein when the radio frequency output power is maximal, the stepping motor stops rotating. The automatic tuning method of the ultrashort wave electrotherapy device is simple, and adjustment is accurate.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to an ultrashort wave electrotherapy instrument and an automatic tuning method thereof. Background technique [0002] The ultrashort wave electrotherapy instrument is mainly used in the rehabilitation physiotherapy department, surgery, internal medicine and other departments of the hospital. Its treatment method is a kind of physical therapy. The device outputs a certain radio frequency power, which has a good effect on the nervous system, cardiovascular system, digestive system, kidney, knot tissue and inflammation. [0003] When the ultrashort wave electrotherapy device is running, it must be tuned to make the output circuit match the human body circuit best, and the efficiency of the device output power is the highest. At present, the existing ultrashort wave electrotherapy instruments are all manually tuned, and the nurse leaves the patient after finishing the tuning...
