Description

Technical Field

[0001] The present invention relates to the technical field of radio frequency heating physiotherapy, and particularly to a radio frequency electrode patch based on a printed board radiator with a temperature acquisition function. Background Art

[0002] Radio frequency thermotherapy devices are one of the health physiotherapy products that are currently popular among people. Their working principle is as follows: high-frequency electromagnetic waves are generated by a radio frequency generator, and after filtering, power amplification, and coupling detection, they are then transmitted to a radio frequency radiator to radiate the electromagnetic waves. Human tissues absorb the electromagnetic wave energy to achieve the therapeutic physiotherapy effect. Generally, the radiator of a radio frequency thermotherapy device consists of paired metal plate electrodes, and a coaxial cable is used to transmit radio frequency electromagnetic waves between the radio frequency transmitter and the radiator. The power transmission loss is large, and the power and size of the product are both large. It is a fixed installation device and cannot be used portably.

[0003] When a radio frequency thermotherapy device is working, the energy of radio frequency radiation can penetrate the human epidermis and reach deep into the subcutaneous tissue. After the human body absorbs the radio frequency energy, the temperature of the physiotherapy site will rise. If there are no effective measures to control it, the human tissues at the treated site will be damaged due to excessive temperature.

[0004] Currently, the radio frequency thermotherapy devices on the market are all high-power large devices. Generally, there are the following ways to prevent the human tissues at the treated site from being burned: 1. Adopt physical cooling methods, such as applying cold compresses. This method often affects the experience and reduces the compliance of the treated person. 2. Temperature monitoring, measuring the temperature of the human treated site, and terminating the physiotherapy when it exceeds the range. However, this temperature measurement generally requires manually holding a temperature sensor to contact the human treated site to measure under the condition of stopping power output, which is troublesome and cannot ensure the continuity of physiotherapy. 3. According to experience, adopt pulsed power output or control the output power size in a time-sharing manner, but this method will reduce the physiotherapy effect and it is also difficult to ensure that the treated site will not be burned. Summary of the Invention

The radio frequency radiator is designed as a very small printed circuit board and is directly clamped to the radio frequency thermotherapy device host without being conducted by a coaxial cable, greatly reducing the energy transmission loss. Thus, the overall size of the machine can be greatly reduced, meeting the requirements of portable applications. And a temperature sensor is provided on the printed board radiator. The patch can be closely attached to the skin of the treated site, capable of real-time collecting the temperature of the treated site, thus well solving the problem that human tissues are damaged due to excessive temperature when absorbing radio frequency energy.

[0017] 1. The RF radiator is designed as a printed circuit board, which is simple to manufacture, has mature technology and low cost. At the same time, the radiator can be made very small to meet the requirements of portable applications and greatly expand the scope of use of the product.
