Description

RF Low Frequency Stimulator {The low frequency treatment apparatus which uses RF.}

The present invention relates to a low frequency stimulator, and the conventional low frequency stimulator is used for the first time using electricity, but recently, the trend is to reduce the weight and size using a small battery.

However, the wired low frequency stimulator is connected to the control unit and the adhesive pad by a line for transmitting electric signals, which is cumbersome to use and has a limited use distance. , Shoulders, thighs, etc.) can not be used to change the function, you can not change the function currently in operation, you can not check the current function and there is a disadvantage that you can not use the desired function freely.

In case of integrated type, it is a tuning method using transmission coil, which has a problem of high current consumption and difficult control of multi-function.In case of using RF, miniaturization is difficult due to transmission / reception antenna problem, current consumption problem, directional problem, etc. It was difficult to put into practical use.

In order to solve the problems described above, the present invention minimizes the current consumption by miniaturizing and reducing the body weight of the remote control transmitter and the RF receiver incorporating RF, and allowing users to increase the effectiveness of low frequency treatments such as tapping, kneading, acupressure, massage, Various functions such as strong, medium, and weak can be easily controlled remotely, and the purpose is to increase the efficiency of the stimulus and increase the therapeutic effect by converting and outputting different electric polarities on the adhesive pad.

In order to achieve the above object (Fig. 2) the main body (Fig. 2) is turned on and off and the constant voltage control unit 500 for supplying stable power to each stage, RF receiver 400 for receiving the data signal transmitted from the remote control, receiving Microcomputer 100 for performing the data, high voltage generator 200 for generating a high voltage for low frequency treatment, output controller 300 for sending a high voltage to the adhesive pad by changing the polarity according to the set function, the battery The remote control cone for transmission (Fig. 3) includes a function switch for selecting each function, an LED lamp indicating an operation state, a microcomputer 600 for performing a function, and the data output from the microcomputer to an RF signal. SAW resonator 800, RF amplifier 900, the antenna 950, and a battery for.

When the power switch SW1 is pressed to operate the main body (Fig. 2), when the positive voltage divided by R1 / R2 is input through the diode D1 to the constant voltage IC of the constant voltage controller 500, the rated voltage is output. 100 is supplied with constant voltage power and operates normally. At this time, when the “H” signal output from the microcomputer 100 maintains the signal through the diode D2, the constant voltage IC is continuously supplied and operated continuously. .

The constant voltage is also supplied to the RF receiver 400 to be in a reception standby state, and to keep a standby state capable of performing all functions by lighting a lamp LED1 to indicate an operation state. At this time, when a signal transmitted from the remote control is input to the RF receiver 400, the data is received and transmitted to the microcomputer 100, and the microcomputer 100 determines whether the signal is pounding, kneading, acupressure, or massage. Proceed by selecting the appropriate action. When the signal is read, the boost pulse waveform is sent to the transistor Q8 through the resistor R17. The transistor Q8 shakes the coil L1 to generate a high voltage. As shown in FIG. If T2 is short and the pulse quantity T3 is large, the voltage rises. If the pulse width T1 is narrow, the pulse pause T2 is long, and the pulse quantity T3 is small, the voltage decreases. The function is changed according to the pulse quantity T3 and the waiting time T4. The high voltage is rectified by the diode D3 and stored in the capacitor C2. The stored high voltage is a signal sent from the microcomputer 100 to operate the transistor Q6 through the resistor R6, and this signal is again applied to the transistors Q2 and Q5. ) And the high voltage (+) stored in the capacitor (C2) is supplied to the adhesive pad 1 through the transistor (Q2) and the resistor (R14), the (-) end of the transistor (Q5) is operated by the resistor (R15) It is supplied to the adhesive pad 2 via. On the contrary, on the contrary, since the high voltage stored in the capacitor C2 operates the transistor Q7 through the resistor R7, the transistors Q3 and Q4 operate to reverse electricity. That is, the first flows electricity from the adhesive pad 1 to the adhesive pad 2 and the second flows the electricity from the adhesive pad 2 to the adhesive pad 1 to maximize the therapeutic effect. Function selection includes threshing, kneading, acupressure, massage, etc. The strength can be set to 3 steps, 3 steps, and 3 steps. The electrical period or the magnitude of the voltage depends on the setting function and see FIG. After 15 minutes of operation, it automatically stops and goes to stand-by, but when it is stopped, press the power switch SW1 again to operate the transistor Q1 through the resistor R5 and supply it to the diode D2. When the "H" power is applied to the microcomputer 100 through the resistor R18, the "H" supplied to the diode D2 is cut off programmatically, thereby making the constant voltage IC control input terminal "L". This stops the output and stops all functions, resulting in almost no current consumption.

The remote controller wakes up from the sleep mode when the microcomputer 600 is in the sleep mode and presses the function switches SW2 to SW4, and supplies a digital signal suitable for the function to the resistor R20, which is supplied to the SAW resonator SAW1. The signal is converted into an RF signal and input to the base terminal of the transistor Q9. The capacitor C3, C4, and C5 and the air conditioner are coupled to the main body by the receiving antenna 2 950. The switches SW5 and SW6 are intensity setting switches. The minimum transmission frame is 12 times and continuously transmitted as long as it is pressed. The display lamps LED2 to LED7 are function display lamps.

As described above, it is possible to use a low frequency stimulator for a long time by using a battery with low power consumption by minimizing the antenna by embedding the RF receiver, increasing the therapeutic effect by easily changing the low frequency voltage polarity repeatedly, and using RF. There is no discomfort of the limited adhesion area due to, and also by simply attaching any part of the affected area without being constrained, it is characterized by maximizing the low frequency stimulation effect by using while setting and confirming various functions remotely.
