Description

Technical Field

[0001] The present invention belongs to the technical field of high-frequency electrotherapy, and in particular relates to a high-frequency electrotherapy protection device and a working method of the high-frequency electrotherapy protection device. Background Art

[0002] High-frequency electrotherapy utilizes biophysical methods to treat illnesses. High-frequency electromagnetic waves penetrate the human body, and their wavelengths are highly penetrating, making it the most commonly used treatment method in rehabilitation therapy.

[0003] Currently, high-frequency electrotherapy generally uses two methods to monitor and protect the treatment process. The first is through questioning and observation by medical staff. However, due to varying levels of proficiency among medical staff, optimal treatment results are often suboptimal, and can even lead to serious burns and other medical accidents. The second method uses methods to collect information such as temperature and blood flow at the treatment site for assessment and protection. This method generally ensures uniform temperature across the treatment area, ultimately preventing medical accidents.

[0004] However, the accuracy of the second type of high-frequency electrotherapy is achieved by directly collecting feedback from the power amplifier output position without considering the energy loss in the subsequent isolation output and energy conversion links. The error is large and the effectiveness of the treatment energy cannot be guaranteed. Summary of the Invention

[0009] The control unit obtains the treatment plan based on human-computer interaction, controls the treatment antenna through the output power amplifier module to reach the initial high-frequency electric field energy after low-power uniform preheating operation at the patient's treatment site, receives signals from the treatment energy and thermal map monitor to monitor the treatment intensity and treatment energy of each treatment point in real time, combines the high-frequency electric field energy of each treatment point with the thermal map changes, generates a point treatment curve, and fine-tunes the high-frequency electric field treatment power through the distributed array capacitor according to the point treatment curve; when the treatment energy exceeds the threshold, a protection signal is generated and sent to the protection action module.

[0042] Compared with the existing technology, the beneficial technical effects of the present invention are: it can directly sample from the treatment circuit, provide direct data basis for the treatment effect, differentiate treatment of different treatment sites, achieve accurate quantitative treatment of disease sites, ensure the effectiveness and accuracy of treatment, and predict treatment accidents in advance, such as providing double protection when there are safety hazards.

[0043] Preferably, a second sampling coupler is provided between the output power amplifier module and the isolation output module, which feeds back the forward and reverse power generated by the output power amplifier module to the control unit through the power detector and the filtering conversion module, and performs proportional integral differential adjustment on the high-frequency electric field generating circuit of the high-frequency electric field treatment unit.

[0068] Existing high-frequency electrotherapy devices sample power from the amplifier output stage for standing wave tuning protection and output power control. The sampled power is simply the amplifier's output power, indirectly reflecting the output power. Alternatively, other high-frequency electric field radiation receiving devices can be used to detect power near the treatment site. The measured power is used only as a reference.

[0069] The present invention directly samples from the treatment circuit, collects the treatment intensity, accumulates the treatment energy acting on the patient's part, and quantitatively analyzes the treatment energy in combination with the changes in the heat map. The heat map comparison of different treatment plans is as follows: Figure 4 a. Figure 4 As shown in b, they are schematic diagrams of heat maps under different treatment energies. The dark / light colors in the figure correspond to high / low treatment energy, that is, the darker the color, the greater the treatment energy; in addition, points A~F and A'~F' are point treatment curves generated after collecting data using the treatment method described in this patent.

[0070] Figure 4 The diagram in a is a schematic diagram of the heat map distribution of the treatment energy during time-sharing treatment of all areas. The treatment energy in the entire treatment area remains basically consistent, thereby generating point treatment curves A to F.

[0071] Differentiate the treatment areas for treatment, and while all areas are treated at different times, apply different powers of targeted treatment to different treatment areas.

[0072] Figure 4 b is to quantitatively analyze the treatment energy according to the treatment method described in this patent, and to perform targeted treatment on the corresponding treatment energy achieved by applying different powers to different treatment areas, and then adaptively generate point treatment curve A according to different treatment energy distribution conditions. ， ~F ， .

[0073] According to the temperature rise change of the patient's treatment area per unit time, the treatment energy and heat changes are digitally quantified to provide a certain data basis for analyzing the treatment results.

[0074] Based on the analysis curve, treatment accidents can be predicted in advance. Based on the analysis curve, abnormal change rates can be predicted in advance. When there are safety hazards, dual protection of shutting down the output and removing the treatment antenna can be implemented.

[0075] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of protection of the technical solution of the present invention.
