Technical Field

[0001] This application relates to the technical field of medical devices, and in particular, to a temperature control heating system and method for the bladder cavity. Background Art

[0002] Bladder cancer is a common malignant tumor of the urinary system worldwide. Epidemiological data shows that its incidence rate in the male population is significantly higher than that in the female population, which may be related to factors such as a higher smoking rate and more occupational exposure opportunities in men.

[0003] The recurrence rate of bladder cancer remains high. Conventional surgical treatment may not be able to completely remove cancer cells, and chemotherapy faces the problems of drug resistance and significant systemic side effects. Hyperthermia, with its unique biological mechanism, brings new opportunities for the treatment of bladder cancer. Bladder thermo-perfusion therapy, which combines hyperthermia and chemotherapy organically, is an effective means for dealing with non-muscle invasive bladder cancer (NMIBC) as a local treatment method. With the cooperation of a thermal environment, chemotherapy drugs are more likely to penetrate into cancer cells, significantly reducing the recurrence rate of NMIBC.

[0046] Embodiment 1:

[0047] Please refer to Figure 1 , Embodiment 1 of this application provides a temperature-controlled heating system for the bladder cavity. This temperature-controlled heating system can be used to heat the mixed liquid of tissue fluid and chemotherapy drug in the bladder and monitor the temperature of the mixed liquid, so as to perform local hyperthermia chemotherapy on patients with bladder cancer. Among them, this temperature-controlled heating system includes an electromagnetic generation module, an electromagnetic energy output electrode, an electromagnetic induction metal float, a temperature measurement sensor 3, a temperature measurement wireless power supply device, a temperature measurement wireless communication device, a control system, and a display module.

[0048] Specifically, the control system is communicatively connected to the electromagnetic generation module, the temperature measurement wireless power supply device, the temperature measurement wireless communication device, and the display module respectively. The electromagnetic generation module emits electromagnetic energy to the electromagnetic energy output electrode, and the electromagnetic energy output electrode sends the electromagnetic energy to the electromagnetic induction metal float by electromagnetic means. The temperature measurement sensor 3 is arranged on the upper end surface of the electromagnetic induction metal float, the temperature measurement wireless power supply device wirelessly emits energy to the temperature measurement sensor 3, and the temperature measurement sensor 3 sends the real-time liquid temperature data in the bladder cavity to the temperature measurement wireless communication device through a wireless signal, and the temperature measurement wireless communication device conducts data interaction with the control system.

[0049] Here, the electromagnetic generation module transfers electromagnetic energy to the electromagnetic induction metal floating ball through the electromagnetic energy output electrode. Using the principle of electromagnetic induction, an eddy current effect is generated to heat the metal floating ball 1, thereby heating the mixed liquid in the bladder. Precise heating can be achieved, effectively avoiding the situations of local overheating or insufficient heating, providing a suitable temperature environment for local hyperthermia chemotherapy of bladder cancer, so as to achieve a clinical effect where hyperthermia plus chemotherapy has 1 + 1 ≥ 2. In this embodiment, the temperature control heating system heats the mixed liquid in the bladder cavity to 43 - 45 °C for hyperthermia chemotherapy.

[0050] The temperature measurement sensor 3 is arranged on the electromagnetic induction metal floating ball and can measure the temperature of the mixed liquid in the bladder cavity in real time. The temperature measurement wireless power supply device wirelessly powers the temperature measurement sensor 3 to ensure its normal operation. The temperature measurement sensor 3 sends the real-time temperature data to the temperature measurement wireless communication device through wireless signals and then conducts data interaction with the control system, enabling the control system to obtain temperature information in real time. According to the received temperature data, the control system can regulate the electromagnetic generation module to achieve precise control of the heating process. If the temperature is too high, the control system can reduce the output power of the electromagnetic generation module; if the temperature is too low, the power can be increased to ensure that the temperature of the mixed liquid remains within the set range, thereby improving the effect and safety of hyperthermia chemotherapy. The control system is communicatively connected to the display module and can display the real-time temperature data and other relevant information, facilitating medical staff to view at any time and timely understand the temperature situation in the bladder cavity, so as to make corresponding decisions and adjustments.

[0051] This application uses a computer control system. By establishing an intelligent big data model, intelligent calculations are performed for different bladder cavity sizes and liquid volumes, and electromagnetic energy is output to achieve high-precision temperature control of the liquid in the bladder cavity. The display module is a touch display, which can set the current control temperature in the bladder cavity, simultaneously display the real-time temperature of the mixed liquid in the bladder cavity fed back, and establish a time - electromagnetic output power - bladder cavity temperature icon curve display, facilitating medical staff to view historical data and conduct treatment evaluations.

[0052] Please refer to Figure 2 , in a specific embodiment, the electromagnetic induction metal floating ball includes a metal floating ball 1 and a protective silica gel 2. Among them, the protective silica gel 2 has a hollow structure. The protective silica gel 2 is used to wrap the outside of the metal floating ball 1, and the outer surface of the metal floating ball 1 contacts the liquid in the bladder cavity.

[0053] In this regard, the protective silica gel 2 wraps around the outside of the metal floating ball 1, which can separate the metal floating ball 1 from the tissues in the bladder, prevent the metal floating ball 1 from directly contacting human tissues, prevent the metal from causing adverse stimulation or damage to the human body, and play a role in protecting human tissues. The protective silica gel 2 has a hollow structure, which can not only effectively transfer the heat generated by the metal floating ball 1 to the mixed liquid in the bladder cavity to ensure the heating effect, but also enable the mixed liquid to be in full contact with the metal floating ball 1, facilitating the temperature measurement sensor 3 to accurately measure the liquid temperature. The metal floating ball 1 in the bladder is indirectly heated by electromagnetic energy to heat the mixed liquid in the bladder cavity, and there is no need to transmit energy through a wire, and accurate control of electromagnetic energy output can be achieved. In this embodiment, the working resolution of the heating energy can reach ±0.1W.

[0054] Furthermore, the temperature measurement sensor 3 is installed on the protective silica gel 2, and the temperature data is transmitted through a wireless transmission method. The temperature measurement sensor 3 senses the temperature of the liquid in the bladder in real time, converts it into a digital signal and wirelessly sends the data to the temperature measurement wireless communication device, and the digital signal is transmitted to the control system through serial communication. The protective silica gel 2 provides a stable installation position for the temperature measurement sensor 3, ensuring that the temperature measurement sensor 3 can accurately measure the temperature of the liquid around the metal floating ball 1, and at the same time avoiding the interference that may be generated by the direct contact between the temperature measurement sensor 3 and the metal floating ball 1, ensuring the accuracy and stability of temperature measurement. In this embodiment, the temperature measurement accuracy of the temperature measurement sensor 3 can reach ±0.1°C.

[0055] In a specific embodiment, the metal floating ball 1 is hollow inside and has a smooth outer surface. The hollow design inside reduces the overall weight of the metal floating ball 1, making it easier to float in the mixed liquid in the bladder, better adapting to the environment in the bladder, and avoiding exerting too much pressure on the bladder wall or causing discomfort due to excessive weight. At the same time, appropriate buoyancy can ensure that the metal floating ball 1 is in a suitable position in the liquid, which is beneficial to uniformly heating the surrounding mixed liquid. The smooth outer surface of the metal floating ball 1 can reduce the flow resistance of the liquid on the surface of the metal floating ball 1, enabling the liquid to flow more smoothly around it, thereby promoting the uniformity of heat exchange. On the other hand, the smooth outer surface can reduce the risk of friction and damage to the tissues on the inner wall of the bladder cavity. When the metal floating ball 1 sways or changes position with the liquid, it will not scratch the bladder wall due to the rough surface, which helps to protect tissues such as the bladder mucosa, reducing the discomfort of the patient during the treatment process and potential tissue damage.

[0056] In a specific embodiment, the electromagnetic energy output electrode is a hollow cylinder. The hollow cylindrical structure can make the electromagnetic energy form a relatively uniform magnetic field distribution inside it, which is beneficial to efficiently and stably transmit the electromagnetic energy generated by the electromagnetic generation module to the electromagnetic induction metal floating ball. This structure can reduce the loss during the energy transmission process and improve the energy transmission efficiency.

[0057] In a specific embodiment, the electromagnetic generation module is connected to the electromagnetic energy output electrode through an aviation plug and a cable for electromagnetic energy output, receives electromagnetic startup and power output data through the serial communication interface with the control system, and starts the electromagnetic generator and outputs the corresponding energy output.

[0058] Embodiment 2:

[0059] Please refer to Figure 3 , Embodiment 2 of the present application provides a temperature control heating method for the bladder cavity, which is implemented based on the temperature control heating system in Embodiment 1. The temperature control heating method includes the following steps:

[0060] S1. Implant the electromagnetic induction metal float into the treatment site in the bladder cavity. Ensure that the electromagnetic induction metal float can be accurately placed at the position where thermochemotherapy is required, so that the heating effect directly acts on the lesion site, improving the pertinence and effect of treatment and reducing the impact on other normal tissues.

[0061] S2. Medical staff input a heating request on the display module. This provides a convenient way for medical staff to start the temperature control heating system, facilitating medical staff to control the start of the heating process according to the specific conditions and treatment needs of the patient.

[0062] In a specific embodiment, step S2 includes steps S101 to S102: S101. The display module displays the set electromagnetic output power and the set liquid temperature, and medical staff input the set electromagnetic output power and the set liquid temperature; S102. After the medical staff complete the data input, input the heating request.

[0063] The display module displays the set electromagnetic output power and the set liquid temperature. Medical staff can accurately input appropriate parameters according to the specific condition, physical condition and treatment needs of the patient. The set electromagnetic output power determines the intensity of the electromagnetic energy generated by the electromagnetic generation module, and the set liquid temperature is the target value of heating. In this way, the heating process can be precisely controlled, avoiding blind heating, making the heating more in line with the treatment requirements of individual patients, and improving the treatment effect. Precisely setting the heating parameters helps prevent damage to the bladder tissue caused by too high temperature or failure to achieve the treatment effect due to too low temperature. For example, reasonably setting the set liquid temperature according to the patient's tolerance to heat can avoid adverse reactions such as tissue scalding caused by too high temperature, ensuring the safety of the patient during thermochemotherapy. In this embodiment, the accuracy of the electromagnetic output power reaches ±1W.

[0064] The display module provides clear parameter input prompts, reducing the operation difficulty for medical staff. Even relatively inexperienced medical staff can accurately input parameters and submit requests according to the prompts, improving the convenience and efficiency of operation. Different patients have different conditions and physical conditions, and there are also differences in the needs for hyperthermia chemotherapy. By allowing medical staff to input personalized set electromagnetic output power and set liquid temperature, it can better meet the special treatment needs of each patient, implement personalized treatment plans, and improve the pertinence and effectiveness of treatment.

[0065] S3. The control system receives the heating request, controls the electromagnetic generation module to generate raw electromagnetic energy, and simultaneously sends a power supply signal to the temperature measurement wireless power supply device. The control system coordinates the work of the electromagnetic generation module and the temperature measurement wireless power supply device to ensure that while generating the electromagnetic energy required for heating, it provides a working power supply for the temperature measurement sensor 3, enabling the temperature monitoring function to be synchronously turned on.

[0066] S4. The electromagnetic energy output electrode receives the raw electromagnetic energy and transmits the raw electromagnetic energy to the electromagnetic induction metal floating ball in an electromagnetic manner. It realizes the transfer of electromagnetic energy from the electromagnetic generation module to the electromagnetic induction metal floating ball, providing an energy source for generating heat for the metal floating ball 1, and ensuring the high efficiency and stability of energy transmission.

[0067] S5. The electromagnetic induction metal floating ball generates an eddy current effect to convert the raw electromagnetic energy into heat energy, and the electromagnetic induction metal floating ball exchanges heat with the liquid in the bladder cavity to heat the liquid in the bladder cavity. Using the principle of electromagnetic induction to convert electrical energy into heat energy to heat the liquid in the bladder cavity can achieve precise heating, effectively avoiding the situation of local overheating or insufficient heating, and providing a suitable temperature environment for local hyperthermia chemotherapy of bladder cancer. In this embodiment, the efficiency of converting electromagnetic energy into heat energy is as high as over 98%, and only a small amount of electromagnetic energy output is required to complete precise temperature control.

[0068] S6. The temperature measurement wireless power supply device emits wireless energy to supply power for the operation of the temperature measurement sensor 3. It ensures that the temperature measurement sensor 3 can work continuously and stably, provides power support for accurately measuring the liquid temperature in the bladder cavity in real time, and ensures the reliability of temperature monitoring.

[0069] S7. The temperature measurement sensor 3 real-time detects the liquid temperature data in the bladder cavity and transmits the temperature data to the temperature measurement wireless communication device in real time. It real-time obtains the temperature information of the mixed liquid in the bladder cavity, provides feedback data for the control system, enables the control system to timely understand the heating situation, and provides a basis for subsequent regulation.

[0070] S8. The temperature measurement and wireless communication device feeds back the temperature data to the control system in real time, achieving fast transmission of temperature data from the temperature measurement sensor 3 to the control system, ensuring that the control system can obtain the latest temperature information in a timely manner for timely adjustment.

[0071] S9. The control system calculates the temperature data to obtain data information and feeds back the data information to the display module, processes and analyzes the temperature data, and presents valuable information to medical staff to facilitate their intuitive understanding of the temperature situation in the bladder cavity for corresponding decision-making and adjustment.

[0072] In a specific embodiment, step S9 includes steps S201 to S203:

[0073] S201. The control system calculates the actual electromagnetic output power from the temperature data through a temperature control algorithm.

[0074] In this embodiment, the temperature control algorithm includes the following steps:

[0075] Step 1: The user can touch the display module to set the set liquid temperature T of the mixed liquid in the bladder.

[0076] Step 2: The computer transmits the set liquid temperature T and the heating request signal to the control system.

[0077] Step 3: The control system receives the initial temperature T1 of the mixed liquid in the bladder.

[0078] Step 4: The control system calculates the difference T2 between T1 and T:

[0079] When T2≥5°C, the power output is 100%.

[0080] When 5°C>T2≥3°C, the power output is 70%.

[0081] When 3°C>T2≥2°C, the power output is 50%.

[0082] When 2°C>T2≥1°C, the power output is 30%.

[0083] When 1°C>T2≥0.5°C, the power output is 20%.

[0084] When 0.5°C>T2≥0.3°C, the power output is 10%.

[0085] When 0.3°C>T2≥0.1°C, the power output is 5%.

[0086] When 0.1°C>T2≥0.0°C, the power output is 0%.

[0087] Step 5: Perform temperature control in a loop.

[0088] Step 6: Stop heating after the treatment time countdown ends.

[0089] This enables the control system to accurately determine the current required electromagnetic output power based on the real-time monitored temperature data. The temperature control algorithm can comprehensively consider various factors, such as the initial temperature T1 of the liquid, the heating rate requirement, the heat conduction characteristics, etc., so as to dynamically adjust the electromagnetic output power, ensure the accuracy of the heating process, and keep the temperature of the mixed liquid in the bladder cavity stable within the target range.

[0090] S202. The control system calculates the temperature deviation value between the set liquid temperature and the actual liquid temperature in the temperature data, and obtains the power deviation value between the set electromagnetic output power and the actual electromagnetic output power. By quantifying these deviations, medical staff or the control system can clearly understand the difference between the current heating state and the target state. The temperature deviation value reflects the gap between the actual liquid temperature and the set liquid temperature, and the power deviation value reflects the difference between the actual electromagnetic output power and the set electromagnetic output power. These deviation values provide a clear basis for subsequent adjustment of the heating process, helping to take timely measures to correct the deviations and ensure the stability and effectiveness of the treatment process.

[0091] S203. The control system feeds back the actual liquid temperature, temperature deviation value, actual electromagnetic output power, and power deviation value to the display module. These information are presented on the display module, providing comprehensive and intuitive heating state data for medical staff. Medical staff can quickly understand the gap between the actual temperature and the set temperature of the liquid in the bladder cavity, as well as the actual situation of the electromagnetic output power and its deviation from the set power according to these data. This helps medical staff make accurate decisions, such as whether to further adjust the electromagnetic output power to achieve better treatment effects while ensuring the safety of patients.

[0092] Through steps S201 - S203, the control system can automatically calculate and adjust relevant parameters according to the actual situation and feedback information in a timely manner, reflecting the self-adaptability and intelligence of the control system. The control system can continuously self-adjust according to the temperature change and deviation situation, without the need for frequent manual intervention by medical staff, improving the automation degree of the treatment process, reducing the possibility of human operation errors, and enhancing the reliability and stability of the entire temperature control heating system. Precise temperature control and timely adjustment of deviations can ensure that the temperature of the liquid in the bladder cavity always remains within the appropriate hyperthermia chemotherapy temperature range (for example, 43 - 45°C). A stable temperature environment helps to improve the effect of hyperthermia chemotherapy, enhance the killing effect of chemotherapy drugs on cancer cells, and reduce the possible adverse effects on normal tissues caused by temperature fluctuations, thereby improving the success rate of treatment and the prognosis quality of patients.

[0093] S10. The control system adjusts the electromagnetic energy generated by the electromagnetic generation module according to the regulation data input by the medical staff on the display module, and then regulates the thermal energy of the electromagnetic induction metal floating ball, thereby achieving precise control of the heating process. According to the difference between the actual temperature and the set temperature, the output power of the electromagnetic generation module is adjusted in a timely manner to ensure that the temperature of the mixed liquid remains within the set range, thus improving the effectiveness and safety of thermochemotherapy.

[0094] In a specific embodiment, step S10 includes steps S301 to S304: S301. The medical staff inputs regulation data on the display module according to the temperature deviation value and the power deviation value; the regulation data includes the regulated liquid temperature and the regulated electromagnetic output power; S302. The control system receives the regulation data and adjusts the regulated electromagnetic energy generated by the electromagnetic generation module; S303. The electromagnetic energy output electrode receives the regulated electromagnetic energy and transmits it to the electromagnetic induction metal floating ball; S304. The electromagnetic induction metal floating ball converts the regulated electromagnetic energy into regulated thermal energy to regulate the temperature of the liquid in the bladder cavity.

[0095] Since the conditions and constitutions of each bladder cancer patient are different, their responses to thermochemotherapy are also not the same. The temperature deviation value and the power deviation value intuitively reflect the difference between the current heating state and the expected target. Based on the real-time feedback data and combined with the specific situation of the patient, the medical staff can flexibly adjust the treatment parameters and formulate a personalized treatment plan, significantly improving the treatment effect.

[0096] Through steps S301 to S304, the control system adjusts the regulated electromagnetic energy generated by the electromagnetic generation module according to the regulation data input by the user, and then transmits the energy to the electromagnetic induction metal floating ball through the electromagnetic energy output electrode, ultimately achieving the regulation of the temperature of the mixed liquid in the bladder cavity. This process is closely connected, ensuring the coherence of the treatment process, reducing the temperature fluctuations caused by untimely or inaccurate parameter adjustment, and creating a stable environment for thermochemotherapy. During the thermochemotherapy process, the temperature of the liquid in the bladder cavity will be affected by various factors, such as the flow of the liquid and the absorption of tissues. Through real-time monitoring and adjustment, the control system can dynamically adapt to these changes and continuously provide stable temperature support for the treatment, ensuring the smooth progress of the treatment.

[0097] Furthermore, the control system controls the temperature deviation value within ±0.3°C. Hyperthermia and chemotherapy can produce a synergistic effect within a specific temperature range. Precise control of the temperature deviation within ±0.3°C can keep the temperature in the bladder within the range where the synergistic effect of thermochemotherapy is optimal. At this temperature, the uptake and sensitivity of cancer cells to chemotherapy drugs are significantly enhanced. Hyperthermia promotes an increase in the permeability of the cancer cell membrane, making it easier for chemotherapy drugs to enter the cancer cells, thereby greatly enhancing the killing ability against cancer cells. If the temperature fluctuates beyond this range, the synergistic effect of hyperthermia and chemotherapy may be disrupted. If the temperature is too high, cancer cells may enter a stress state due to excessive heat, reducing their sensitivity to chemotherapy drugs; if the temperature is too low, the synergistic effect of hyperthermia on chemotherapy cannot be fully exerted. Controlling the temperature deviation within a very small range can effectively avoid this situation.

[0098] The implementation principle of the temperature control heating method for the bladder cavity in the second embodiment of this application is as follows: This temperature control heating method is based on a specific temperature control heating system. First, an electromagnetic induction metal float is implanted into the bladder treatment site. After the medical staff inputs a heating request, the control system coordinates the electromagnetic generation module to generate electromagnetic energy and sends a power supply signal to the temperature measurement wireless power supply device. The energy is transmitted to the metal float 1 through the electromagnetic energy output electrode to generate heat, heating the mixed liquid in the bladder. At the same time, the temperature measurement wireless power supply device powers the temperature measurement sensor 3. The temperature measurement sensor 3 detects the temperature in real time and feeds it back to the control system through the temperature measurement wireless communication device. After calculation, the data is fed back to the display module, and the control system can adjust the electromagnetic energy of the electromagnetic generation module according to the regulation data input by the medical staff, thereby regulating the thermal energy of the metal float 1, achieving precise, safe, and adjustable heating of the liquid in the bladder cavity, providing a suitable temperature environment for local thermochemotherapy of bladder cancer, and improving the thermochemotherapy effect.

[0099] The above is only the specific implementation manner of this application, but the protection scope of this application is not limited thereto. Any person skilled in the art within the technical scope disclosed in this application can easily think of various equivalent modifications or substitutions, and these modifications or substitutions should all be covered within the protection scope of this application. Therefore, the protection scope of this application should be subject to the protection scope of the claims.
