Description

Technical Field

[0001] The present invention relates to the technical field of radio frequency hyperthermia control, and in particular to a radio frequency hyperthermia control system and a control method. Background Art

[0002] Radiofrequency therapy devices use low-frequency electromagnetic waves to act on diseased tissues in the human body, causing polar water molecules in the tissues to move at high speed, generating heat, and coagulating proteins at low temperatures, causing them to lose their activity. Finally, they are rejected by the body, causing them to fall off, thereby achieving the purpose of treatment.

[0003] Some existing physiotherapy equipment cannot control the temperature of the physiotherapy equipment in a timely manner due to the control method, resulting in poor equipment reliability. Secondly, if the physiotherapy equipment itself encounters an abnormality and the equipment status reminder measures are not in place, different injuries will be caused. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides a radio frequency hyperthermia control system and control method, which solves the problem that the temperature cannot be controlled in time, resulting in poor equipment reliability, and secondly, the inadequate status reminder in the event of an abnormality may cause different injuries.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: a radio frequency hyperthermia control system, comprising:

[0006] The radio frequency information acquisition end is used to obtain the basic information of the target object and transmit it to the parameter information analysis end, where the target object is: radio frequency therapy equipment, and the basic information includes: radio frequency power and temperature.

[0007] The parameter information analysis end is used to obtain the basic information of the target object and analyze it. The target object is analyzed by combining the real-time data of the patient to generate the corresponding analysis results, and the analysis results include: normal results and abnormal results. The real-time data of the patient includes: body surface temperature. Then the normal results are transmitted to the monitoring end, and the abnormal results are transmitted to the power amplifier adjustment end. The specific method of generating the analysis results is as follows:

[0008] The radio frequency power of the target object is obtained as SP, and then the surface temperature of the patient is obtained as W1, and compared with the standard value Wz. If W1 and Wz match each other, it means that the radio frequency power SP of the target object is normal and a normal result is generated. On the contrary, if W1 and Wz do not match, it means that the radio frequency power SP of the target object is abnormal and an abnormal result is generated. It should be noted here that the standard value Wz represents the normal value Wz corresponding to the problem when the radio frequency power is SP acting on the human body surface under normal circumstances, and the temperature matching means that the temperature difference between the two is within a certain range.

[0009] The power amplifier adjustment terminal is used to obtain the transmitted abnormal result and analyze it, generate a corresponding adjustment result by adjusting and analyzing the radio frequency power, and the adjustment result includes: reducing the adjustment signal and increasing the adjustment signal. At the same time, the adjustment result is transmitted to the monitoring terminal, and the specific method of generating the adjustment result is as follows:

[0010] Obtain the patient's body surface temperature W1 corresponding to the abnormal result, and at the same time obtain the standard value Wz, and calculate the temperature difference between the two and record it as Wc. At the same time, judge the positive and negative of the temperature difference. If the calculated temperature difference Wc is less than zero, it means that the patient's body surface temperature W1 is lower than the standard value and generate an increase adjustment signal. On the contrary, if the calculated temperature difference Wc is greater than zero, it means that the patient's body surface temperature W1 is higher than the body surface temperature standard difference and generate a decrease adjustment signal. It should be noted here that under normal circumstances, the physical therapy device uses radio frequency energy for treatment, but the temperature generated on the human body determines whether the physical therapy effect is achieved. If the generated temperature is too low, the physical therapy effect cannot be achieved. On the contrary, if the generated temperature is too high, it will cause damage to the human body surface.

[0011] The monitoring terminal is used to obtain the transmitted adjustment result and analyze it, and at the same time analyze the target object by combining the temperature in the obtained basic information to generate analysis information, and then judge whether it is necessary to perform heat dissipation treatment on the target object according to the analysis information and generate a heat dissipation analysis result. The heat dissipation analysis result includes: normal monitoring result and heat dissipation control result. At the same time, the heat dissipation analysis result is transmitted to the control terminal, and the specific method of generating the heat dissipation analysis result is as follows:

[0012] S1: Obtain the real-time temperature corresponding to the target object recorded as Ws with t as the time period, and obtain the real-time temperature of the target object in the next time period recorded as Ws1. Then calculate the real-time temperature difference of the target object between two adjacent time periods and record it as Wsc, and compare it with the preset value WY; it should be noted here that the preset value WY represents the normal temperature change value, and the specific number is set by the operator himself.

[0013] S2: If Wsc≥WY, it means that the temperature change difference of the target object exceeds the preset value and generate a heat dissipation control result. On the contrary, if Wsc<WY, it means that the temperature change difference of the target object does not exceed the preset value and generate a normal monitoring result. It should be said here that for the temperature change difference exceeding the preset value, the overall device needs to be cooled down, otherwise it can be monitored normally.

[0014] The control end is used to obtain the transmitted heat dissipation control result and analyze it. By analyzing the working efficiency of the heat dissipation device and combining with the real-time temperature of the target object, reasonable adjustment analysis is carried out, and corresponding control information is generated. The control information includes: temperature anomaly information and adjustment information. Then, the generated control information is transmitted to the output end, and the specific method of generating the control information is as follows:

[0015] P1: Record the working duration of the heat dissipation device as T, and at the same time record the temperature difference value of the target object as WDc. Then substitute the two into the formula Calculate the working efficiency Wx of the heat dissipation device per unit time, where θ is an influencing factor and the specific value is set by the operator himself; it should be noted here that the temperature difference WDc of the target object represents the value of the temperature drop after the heat dissipation device works for T time.

[0016] P2: Then calculate the real-time temperature of the target object based on the working time T1 of the heat dissipation device. Substitute T1 and Wx into the formula Ws2 = T1×Wx×θ to calculate the real-time temperature Ws2 of the target object after working for time T1. At the same time, record the real-time temperature of the target object as Ws3, and compare the two. If Ws2≥Ws3, it means that the heat dissipation device works normally and no adjustment is required, and a normal monitoring signal is generated. On the contrary, if Ws2<Ws3, it means that the heat dissipation device works abnormally and needs to be adjusted, and an adjustment signal is generated at the same time; it should be noted here that Ws2 represents the theoretically real-time temperature of the target object calculated according to the heat dissipation efficiency per unit time, and it is judged whether adjustment is required by comparing it with the actual temperature.

[0017] P3: Then analyze the generated adjustment signal and perform analysis and calculation on the target object according to the real-time temperature Ws3 of the target object. The specific calculation method is as follows:

[0018] P31: Obtain the real-time temperature Ws3 of the target object, and at the same time obtain the temperature change value of the target object within the time period t, and compare the temperature change value with the preset value WY. If the temperature change value is less than the preset value, it means that the power of the heat dissipation device needs to be adjusted and an adjustment signal is generated. On the contrary, if the temperature change difference is greater than the preset value, it means that the temperature change is abnormal and temperature anomaly information is generated; it should be noted here that by comparing the change difference of the heat dissipation device's working temperature drop with the preset value, it is judged whether the heat dissipation device needs to be adjusted. For the case where the change difference is greater than the preset value, it means that the temperature change difference of the target object is abnormal and the corresponding device is abnormal. On the contrary, the heat dissipation device needs to be adjusted.

[0019] P32: Obtain the generated adjustment signal, obtain the power of the heat dissipation device, and perform power increase adjustment according to its corresponding power gear to generate corresponding adjustment information. Combined with the actual situation, when the power of the corresponding heat dissipation device does not meet the requirements, the operator increases the power of the heat dissipation device by adjusting the gear corresponding to the heat dissipation device.

[0020] The output end is used to obtain the transmitted control information and display it to the operator through a display device.

[0021] The present invention provides a radio frequency hyperthermia control system and control method. Compared with the prior art, it has the following beneficial effects:

[0022] The present invention makes an overall analysis and judgment based on the temperature generated by the physiotherapy equipment acting on the human body surface, and further analyzes whether the physiotherapy equipment needs to be radio frequency adjusted based on the temperature. Secondly, the temperature generated by the physiotherapy equipment itself during operation is analyzed, the real-time temperature is collected and compared with the normal value to judge whether adjustment is needed, and corresponding adjustment measures are taken. Further, the overall surface temperature of the physiotherapy equipment after adjustment is monitored in real time, and secondary analysis, adjustment and early warning alarm are performed in abnormal situations.

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] Embodiment 1

[0027] See also Figure 1 to Figure 2 , the present application provides a radiofrequency hyperthermia control system, comprising:

[0028] The radio frequency information acquisition end is used to obtain the basic information of the target object and transmit it to the parameter information analysis end, where the target object is: radio frequency therapy equipment, and the basic information includes: radio frequency power and temperature.

[0029] The parameter information analysis end is used to obtain the basic information of the target object and analyze it. The target object is analyzed by combining the real-time data of the patient to generate the corresponding analysis results, and the analysis results include: normal results and abnormal results. The real-time data of the patient includes: body surface temperature. Then the normal results are transmitted to the monitoring end, and the abnormal results are transmitted to the power amplifier adjustment end. The specific method of generating the analysis results is as follows:

[0030] The radio frequency power of the target object is obtained as SP, and then the surface temperature of the patient is obtained as W1, and compared with the standard value Wz. If W1 and Wz match each other, it means that the radio frequency power SP of the target object is normal and a normal result is generated. On the contrary, if W1 and Wz do not match, it means that the radio frequency power SP of the target object is abnormal and an abnormal result is generated. It should be noted here that the standard value Wz represents the normal value Wz corresponding to the problem when the radio frequency power is SP acting on the human body surface under normal circumstances, and the temperature matching means that the temperature difference between the two is within a certain range.

[0031] The power amplifier adjustment end is used to obtain and analyze the abnormal results of the transmission, and generate corresponding adjustment results by adjusting and analyzing the RF power. The adjustment results include: reducing the adjustment signal and increasing the adjustment signal. At the same time, the adjustment results are transmitted to the monitoring end, and the specific method of generating the adjustment results is as follows:

[0032] The patient's body surface temperature W1 corresponding to the abnormal result is obtained, and the standard value Wz is obtained at the same time, and the temperature difference between the two is calculated and recorded as Wc. At the same time, the positive and negative of the temperature difference is determined. If the calculated temperature difference Wc is less than zero, it means that the patient's body surface temperature W1 is lower than the standard value and an increase adjustment signal is generated. On the contrary, if the calculated temperature difference Wc is greater than zero, it means that the patient's body surface temperature W1 is higher than the standard deviation of the body surface temperature and a decrease adjustment signal is generated. It should be noted here that under normal circumstances, physical therapy equipment uses radio frequency energy for treatment, but the temperature generated on the human body determines whether the physical therapy effect is achieved. If the temperature generated is low, the physical therapy effect cannot be achieved. On the contrary, if the temperature generated is too high, it will cause damage to the human body surface.

[0033] The monitoring end is used to obtain the transmitted adjustment results and analyze them. At the same time, it analyzes the target object in combination with the temperature in the basic information obtained to generate analysis information. Then, according to the analysis information, it is determined whether the target object needs to be cooled and a cooling analysis result is generated. The cooling analysis result includes: normal monitoring results and cooling control results. At the same time, the cooling analysis result is transmitted to the control end, and the specific method of generating the cooling analysis result is as follows:

[0034] S1: Obtain the real-time temperature corresponding to the target object at time period t, denoted as Ws, and obtain the real-time temperature of the target object in the next time period, denoted as Ws1. Then calculate the difference in the real-time temperature of the target object between two adjacent time periods, denoted as Wsc, and compare it with the preset value WY. Here, it should be noted that the preset value WY represents the normal temperature change value, and the specific number is set by the operator himself.

[0035] S2: If Wsc≥WY, it means that the temperature change difference of the target object exceeds the preset value and a heat dissipation control result is generated. On the contrary, if Wsc<WY, it means that the temperature change difference of the target object does not exceed the preset value and a normal monitoring result is generated. Here, it should be noted that for the temperature change difference exceeding the preset value, the overall device needs to be heat-dissipated and regulated, and on the contrary, normal monitoring can be carried out.

[0036] The regulation end is used to obtain the transmitted heat dissipation control result and analyze it. By analyzing the working efficiency of the heat dissipation device and combining the real-time temperature of the target object, reasonable adjustment and analysis are carried out, and corresponding regulation information is generated. The regulation information includes: temperature anomaly information and adjustment information. Then the generated regulation information is transmitted to the output end, and the specific way of generating the regulation information is as follows:

[0037] P1: Obtain the working duration of the heat dissipation device, denoted as T, and at the same time obtain the temperature difference value of the target object, denoted as WDc. Then substitute the two into the formula Calculate the working efficiency Wx of the heat dissipation device per unit time, where θ is an influencing factor, and the specific value is set by the operator himself. Here, it should be noted that the temperature difference WDc of the target object represents the value of the temperature drop after the heat dissipation device works for T time.

[0038] P2: Then calculate the real-time temperature of the target object based on the working time T1 of the heat dissipation device. Substitute T1 and Wx into the formula Ws2 = T1×Wx×θ to calculate the real-time temperature Ws2 of the target object after working time T1. At the same time, obtain the real-time temperature of the target object, denoted as Ws3, and compare the two. If Ws2≥Ws3, it means that the heat dissipation device works normally and no adjustment is required, and a normal monitoring signal is generated. On the contrary, if Ws2<Ws3, it means that the heat dissipation device works abnormally and needs to be adjusted, and an adjustment signal is generated at the same time. Here, it should be noted that Ws2 represents the theoretically real-time temperature of the target object calculated according to the heat dissipation efficiency per unit time. By comparing it with the actual temperature, it is judged whether adjustment is required.

[0039] Specifically, when the calculated real-time temperature is higher than the actually measured temperature, it means that the temperature corresponding to the calculated cooling of the heat dissipation device exceeds the measured temperature and does not need to be adjusted. Otherwise, it means that the temperature corresponding to the calculated cooling does not exceed the actually measured temperature and needs to be adjusted.

[0040] P3: Then analyze the generated adjustment signal and analyze and calculate the target object according to the real-time temperature Ws3 of the target object. The specific calculation method is as follows:

[0041] P31: The real-time temperature Ws3 of the target object is obtained, and the temperature change value of the target object within the time period t is obtained, and the temperature change value is compared with the preset value WY. If the temperature change value is less than the preset value, it indicates that the power of the heat dissipation device needs to be adjusted and an adjustment signal is generated. Otherwise, if the temperature change difference is greater than the preset value, it indicates that the temperature change is abnormal and temperature abnormality information is generated. It should be noted here that whether the heat dissipation device needs to be adjusted is determined by comparing the change difference of the cooling device with the preset value. If the change difference is greater than the preset value, it indicates that the temperature change difference of the target object is abnormal, and the corresponding device is abnormal. Otherwise, the heat dissipation device needs to be adjusted.

[0042] P32: Obtain the generated adjustment signal, obtain the power of the heat dissipation device, and perform power increase adjustment according to its corresponding power gear to generate corresponding adjustment information. Combined with the actual situation, when the power of the corresponding heat dissipation device does not meet the requirements, the operator increases the power of the heat dissipation device by adjusting the gear corresponding to the heat dissipation device.

[0043] The output end is used to obtain the transmitted control information and display it to the operator through a display device.

[0044] A radiofrequency thermal therapy control method, the method specifically comprising the following steps:

[0045] Step 1: Obtain the radio frequency power of the radio frequency therapy device and the patient's body surface temperature, and determine whether the radio frequency power of the radio frequency therapy device needs to be adjusted by analyzing the patient's body surface temperature and generating an analysis result;

[0046] Step 2: Analyze the analysis results based on the patient's body surface temperature, and generate corresponding adjustment results based on the difference between the patient's body surface temperature and the standard value;

[0047] Step 3: Obtain the adjustment result and analyze it in combination with the temperature information of the radio frequency therapy device to obtain analysis information, comprehensively analyze the information to determine whether the radio frequency therapy device needs to be cooled and generate a cooling analysis result;

[0048] Step 4: Then analyze the heat dissipation analysis results, and obtain the working efficiency of the heat dissipation equipment, and combine the real-time temperature of the radio frequency therapy equipment to make reasonable adjustments and analysis to generate corresponding control information.
