The bottom edge of the high frequency handpiece has four holes in up, down, left and right, and when the four holes are blocked, the high frequency stimulator operates and the operation of the device stops when two or more holes are opened. The hole of the high frequency handpiece is connected to the tube so that the air pressure sensor always measures the pressure to determine whether the device is operating. The inside of the high frequency handpiece is connected through a tube in a hole, the tube is characterized in that the two holes facing each other are connected to each other diagonally. Each of the two connected pipes is connected to two air pressure sensors, one by one, and constitutes a high frequency stimulator including a control unit for stopping the operation of the device by reading a signal of the air generating PUMP and the air pressure sensor.

The present invention relates to a high-frequency stimulator that is a medical electrical device, and more particularly, by measuring the pressure of the pipe connected through the hole in the high-frequency handpiece is activated when the hole is blocked and does not operate when the hole is open. Does not relate to a high frequency stimulator.

The high frequency stimulator is for preventing the burn of the skin tissue.

In general, when the high frequency stimulator energizes the high frequency current to the human body by vibration of the piezoelectric ceramic 7h inside the high frequency handpiece, heat is generated in the tissue. This is called deep fever. This means that whenever a high frequency electrical energy is applied, the direction of the current changes. This is because molecules constituting tissues vibrate and rub against each other to generate biothermal due to rotational movement, twisting and collision movement. High-frequency currents that do not stimulate the sensory and motor nerves can heat up specific areas of body tissues without causing discomfort or muscle contraction in the body.

High-frequency energy converted into bio-thermal energy increases the temperature of tissues and enhances cell function and increases blood flow.

In the prior art, a high frequency stimulator was generated by treating a high frequency in a high frequency handpiece.

In the prior art described above, when the radio frequency handpiece and the skin tissue come into contact, the operator grasps the high frequency handpiece and rubs the skin. However, the difference in output was significantly different depending on the area touched during the procedure. As the contact surface with the skin tissue became smaller, the output was concentrated and burns occurred.

Accordingly, the present invention has been made to solve the above problems, the object of the present invention is to operate when the high-frequency handpiece is a large contact area with the skin tissue and the contact area is small, the pressure of two or more holes If this becomes small, the operation stops. The air is ejected from the PUMP (2a) to the four holes to maintain a constant pressure when the high frequency handpiece is in contact with a large area of the skin tissue. If the pressure is maintained, the unit will be activated. If the pressure is reduced, the unit will stop.

In order to achieve the above object, the present invention provides a high-pressure handpiece 3 having four holes 7a, 7b, 7c, and 7d, and an air pressure sensor for measuring the air pressure of the pipes 7e and 7f connected to the holes. 2b and 2c) and a high frequency stimulator including a PUMP 2a for injecting air into the tube.

It is preferable to use air pressure to observe the contact between the high frequency handpiece and the skin tissue according to the present invention.

In order to use the air pressure, air is generated in the PUMP 2a and discharged through the air tubes 7e and 7f to the holes 7a, 7b, 7c and 7d of the high frequency handpiece.

Here, the air pressure sensor measures the air pressure between the PUMP and the air pipe. The measured air pressure is transmitted to the controller, and the controller operates when the air pressure is high and stops when the pressure decreases.

If the high frequency handpiece is in good contact with the skin tissue, all of the holes will be blocked and the air pressure will increase. However, when rubbed during the procedure, sometimes the contact is not opened, the hole is opened and the internal air is discharged out to weaken the pressure inside the air pipe. If the contact area between the high frequency handpiece and the skin tissue is small, the output is concentrated on the contact area due to the high frequency characteristics, resulting in high heat and burns. In order to prevent such a case, when the contact area becomes small, all four holes are not contacted at the edges, so the pressure is weakened, and the high frequency stimulator is stopped.

The high frequency stimulator is equipped with two air pressure sensors 2b and 2c, and the air pressure sensor 2b is connected to the air pipe 7e, and the air pipes are connected to two holes 7a and 7c which are not adjacent to each other. , The other air pressure sensor 2c is preferably connected to the air tube 7f and the air tube is connected to the two holes 7b and 7d.

Hereinafter, with reference to the accompanying drawings, to describe the high-frequency stimulator to operate and stop the device by measuring the air pressure according to an embodiment of the present invention.

1 is a schematic diagram of a high frequency stimulator according to an embodiment of the present invention.

Referring to Figure 1, the present invention reads the signal of the air pressure sensor, the control unit 1 for determining the operation and stop of the device, the PUMP (2a) for generating air, the air pressure sensor (2b, 2c) for measuring the air pressure, treatment It consists of a high frequency handpiece. The control unit generates air in the PUMP, determines the operation by reading the signal of the air pressure sensor, and generates a high frequency in the high frequency handpiece.

Next, the high frequency handpiece of the present invention will be described.

2, 3 and 4, a high frequency handpiece connected to the high frequency stimulator of the present invention is configured. There may also be four holes in the bottom edge of the high frequency handpiece. Four holes may be connected to an air tube inside the high frequency handpiece, and two holes not adjacent to each other may be connected to one tube.

As described above, the present invention is a hole in the bottom of the high-frequency handpiece in contact with the skin in the high-frequency stimulator, applying a constant air pressure to the hole, by measuring the air pressure contact state between the high-frequency handpiece and the skin tissue Can be identified. When the contact state between the high frequency handpiece and the skin tissue is smooth, the output is output. When the contact surface decreases, the device is stopped to prevent the burn due to the output concentration phenomenon according to the contact area of the high frequency stimulator. .

In addition, by connecting two holes which are not adjacent to each other among the four holes on the bottom of the high frequency handpiece, when the two adjacent holes become smaller in pressure, the two pneumatic sensors measure the pressure weakening, thereby effectively reducing the contact area. You can check it.
