Diathermanous type high-frequency therapeutic device

Abstract

The invention relates to a diathermanous type high-frequency therapeutic device. The diathermanous type high-frequency therapeutic device comprises a step-down transformer, a first rectifying and filtering circuit, a second rectifying and filtering circuit, a voltage regulation circuit, a filtering high-frequency current-blocking circuit, an LC self-excited oscillation circuit and two electrodes; mains supply is connected with the first primary coil of the step-down transformer; the first secondary coil of the step-down transformer is connected with the input end of the first rectifying and filtering circuit; the output end of the first rectifying and filtering circuit is connected with the input end of the voltage regulation circuit; the output end of the voltage regulation circuit is connected with the high-potential voltage input end of the LC self-excited oscillation circuit through the filtering high-frequency current-blocking circuit; the second secondary coil of the step-down transformer is connected with the input end of the second rectifying and filtering circuit; and the output end of the second rectifying and filtering circuit is connected with the low-potential voltage input end of the LC self-excited oscillation circuit; and the output end of the LC self-excited oscillation circuit is the output end of the diathermanous type high-frequency therapeutic device of the invention and is connected with the first electrode and the second electrode. The diathermanous type high-frequency therapeutic device of the invention not only can kill harmful bacteria and harmful cells, but also can break down organic acids, remove the pain of a patient and has a remarkable thermal therapeutic effect.

Description

[0001] (1) Technical field [0002] The invention relates to a medical instrument, in particular to a device for thermally treating certain diseases in the human body. [0003] (2) Technical background [0004] In CN203400407U, a utility model patent titled "In vitro deep high-frequency source capacitive field hyperthermia device" is disclosed, which includes a power supply circuit, a filament power supply circuit, a high-voltage boost circuit, a main control and display board, and a short-wave emission output circuit; Its shortwave transmitter output circuit is actually a tube with a frequency of 13.56MHz. This device radiates the short wave generated by the electron tube to the human body located between the two electrodes for hyperthermia through the upper and lower electrodes. The two electrodes are not in contact with the human body, and the heating depth can reach 25cm. Although this device has an effect on the treatment of some diseases in the human body, it has the fol...

[0006] 2. The cost is too high and the efficiency is low: the output power of 600W is not only expensive, but also the radiated short-wave power must be much lower than 600W, resulting in a great waste of energy

[0010] Cancer is one of the persistent diseases that are difficult to solve for human beings. At present, radiotherapy, chemotherapy or surgery are usually used to treat cancer patients. The biggest shortcoming of radiotherapy and chemotherapy is that it kills cancer cells and a large number of normal tissue cells at the same time, so that the survival rate of patients is increased. very low
