Description

Technical Field

[0001] This invention relates to the field of rehabilitation nursing technology, and more specifically, to a disposable temperature monitoring and proportioning sitz bath system. Background Technology

[0002] Sitz baths are a method of local care that involves immersing the buttocks in medicated or warm water. They are widely used in the treatment of anorectal diseases, gynecological inflammation, and postoperative rehabilitation. Disposable sitz bath devices are gradually being adopted in the medical and nursing field because they can avoid cross-infection and ensure hygiene and safety.

[0003] However, traditional disposable sitz bath devices have many limitations: temperature control relies on manual adjustment, which can easily lead to large fluctuations in water temperature due to changes in ambient temperature or improper operation, affecting the nursing effect or even causing scalding; the ratio of medicine to water is mostly estimated based on experience, making it difficult to ensure the accuracy of concentration, which may weaken the therapeutic effect; the liquid level lacks effective monitoring, which can easily lead to interruption of nursing care due to liquid evaporation or overflow; the whole process lacks a real-time feedback mechanism, making it impossible to detect abnormalities in temperature, ratio, and liquid level in a timely manner, and making it difficult to make dynamic adjustments according to the actual situation, which seriously affects the safety and effectiveness of nursing care.

[0004] Therefore, it is necessary to design a temperature monitoring and proportioning sitz bath system based on disposable use to solve the problems of unstable temperature control, insufficient proportioning accuracy, lack of liquid level management, and lack of real-time feedback and adjustment in traditional disposable sitz bath devices. Summary of the Invention

[0005] In view of this, the present invention proposes a temperature monitoring and proportioning sitz bath system based on disposable use, which aims to solve the problems of unstable temperature control, insufficient proportioning accuracy, lack of liquid level management and lack of real-time feedback adjustment in traditional disposable sitz bath devices.

[0006] On one hand, this invention proposes a temperature-monitored sitz bath system based on disposable use, comprising: The inner tub is used to hold the sitz bath liquid; The outer barrel has its top fixed to the lower surface of the top of the inner barrel, forming a sealed space between the outer barrel and the inner barrel, and a temperature-controlled heat-conducting liquid is placed in the sealed space. A temperature monitoring module is installed on the inner wall of the inner tub, and the temperature monitoring module is used to collect the temperature data of the sitz bath liquid in the inner tub in real time. A ratio adjustment module is connected to an external medicine storage container and a water source. The ratio adjustment module is used to control the injection volume of medicine and water according to preset ratio parameters and to adjust the sitz bath liquid into the inner tank. A liquid level detection module is installed on the inner wall of the inner tank, and the liquid level detection module is used to monitor the liquid level height inside the inner tank; A heating and temperature control module is embedded in the inner wall of the outer barrel. The heating and temperature control module is in contact with the temperature-controlled heat transfer fluid in the sealed space. The heating and temperature control module is used to heat and control the temperature of the temperature-controlled heat transfer fluid. The control module is electrically connected to the temperature monitoring module, the proportioning adjustment module, the liquid level detection module, and the heating and temperature control module, respectively. The control module is used to receive the inner tank temperature data collected by the temperature monitoring module. When the temperature data exceeds the preset range, the heating and temperature control module adjusts the temperature of the heat transfer fluid to correct the sitz bath liquid temperature. At the same time, it receives the liquid level data from the liquid level detection module. When the liquid level is lower than the preset threshold, it triggers the proportioning adjustment module to replenish the sitz bath liquid to the inner tank.

[0007] Furthermore, a protective pad is provided on the top edge of the inner tub, and a pressure sensor is provided on the inner side of the protective pad. The pressure sensor is linked with the temperature monitoring module. Based on the pressure sensing signal received by the control module, the temperature monitoring module is triggered to enter the high-frequency monitoring mode. The pressure sensor inside the protective pad is electrically connected to both the control module and the temperature monitoring module.

[0008] Furthermore, when the temperature monitoring module enters the high-frequency monitoring mode, it includes: The temperature monitoring module collects the temperature of the sitz bath liquid in real time, presets the target temperature range, and the first temperature difference range and the second temperature difference range; The control module compares the real-time temperature with the target temperature and calculates the temperature difference: When the real-time temperature is within the target temperature range, it is determined that the temperature is in a stable state, and the control module sends a command to the heating temperature control module to maintain the current power. When the real-time temperature is below the lower limit of the target temperature or above the upper limit of the target temperature: If the temperature difference is within the first temperature difference range, the control module sends a command to the heating temperature control module to adjust the power to the first power. If the temperature difference is within the second temperature difference range, the control module sends a command to the heating temperature control module to adjust the power to the second power. The first power is less than the second power.

[0009] Furthermore, after the heating temperature control module adjusts the power, it also includes: The temperature monitoring module continuously collects the temperature of the sitz bath liquid and presets a retest temperature range, wherein the retest temperature fluctuation range is smaller than the target temperature fluctuation range. The control module compares this temperature with the retest temperature range to determine whether the temperature adjustment has achieved precision and stability. When the temperature is within the retest temperature range, it is determined that the temperature regulation has reached a precise and stable state, and the control module sends a constant temperature maintenance command to the heating temperature control module. When the temperature is not within the retest temperature range, the control module generates a fine adjustment command to control the heating temperature control module to perform step-by-step power fine-tuning in units of the third power. The third power is less than the first power.

[0010] Furthermore, after the heating and temperature control module performs stepped power fine-tuning, it also includes: The liquid level detection module synchronously collects the liquid level of the sitz bath, with a preset liquid level range; The control module compares the current liquid level with a preset liquid level range to determine whether the liquid level is in a preset state: When the liquid level is within the preset liquid level range, the current liquid level is maintained; When the liquid level is lower than the preset lower limit, the control module sends a liquid level calibration command to the proportioning adjustment module to control the injection of a small amount of liquid to adjust the liquid level to the preset liquid level range.

[0011] Furthermore, after adjusting the liquid level, the proportioning adjustment module also includes: The temperature monitoring module collects the temperature of the sitz bath liquid again, and the liquid level detection module collects the adjusted liquid level. The control module calculates the temperature fluctuation value and the liquid level deviation value, and presets the temperature fluctuation threshold and the liquid level deviation threshold. When both the temperature fluctuation value and the liquid level deviation value are less than or equal to the temperature fluctuation threshold and the liquid level deviation value are less than or equal to the liquid level deviation threshold, the temperature-liquid level coordinated regulation is deemed to have met the standard, and the control module records the current parameters. When the temperature fluctuation value is greater than the temperature fluctuation threshold or the liquid level deviation value is greater than the liquid level deviation threshold, the control module triggers the proportioning adjustment module to replenish the liquid according to half of the preset proportion, and adjusts the temperature and liquid level again until the temperature fluctuation value is less than or equal to the temperature fluctuation threshold and the liquid level deviation value is less than or equal to the liquid level deviation threshold at the same time.

[0012] Furthermore, after the proportioning adjustment module replenishes the liquid, it also includes: The control module comprehensively analyzes the real-time data from the temperature monitoring module and the liquid level detection module, calculates the system adjustment compliance rate, and presets the compliance threshold. When the compliance rate is greater than or equal to the compliance threshold, the system is deemed to have completed one adjustment cycle and entered a stable operating state. When the compliance rate is less than the compliance threshold, the control module generates a readjustment command to restart the entire process of adjustment, from high-frequency temperature monitoring to fine-tuning of the ratio.

[0013] Furthermore, it also includes an interaction module, which is located on the outer wall of the outer tub. The interaction module includes touch buttons and a display screen. The interaction module is electrically connected to the control module. The interaction module is used to receive parameters input by the user, such as the target temperature, sitz bath duration, and medicine solution ratio, and to display the current system operating status.

[0014] Furthermore, it also includes a reminder module, which is electrically connected to the control module. The reminder module includes an audible and visual alarm and a vibration unit, used to trigger reminders in the following scenarios: When the sitz bath liquid reaches the target temperature, the first prompt sound will be emitted and accompanied by a flashing green light. When the liquid level is lower than the minimum value of the preset liquid level range or higher than the maximum value of the preset liquid level range, a second prompt sound will be emitted and accompanied by a flashing red light; When the sitz bath time reaches the preset time, a third prompt sound will be emitted and the vibration unit will be activated; If the system fails to reach the target threshold three times in a row, a fault prompt sound will be emitted and a fault code will be displayed on the screen of the interactive module.

[0015] Furthermore, the interaction module is linked with the reminder module. When the reminder module is triggered, the user can perform a confirmation operation through the touch button of the interaction module. After confirmation, the reminder module stops reminding. If no confirmation is received within ten seconds, the reminder module will increase the reminder intensity until the user confirms or the system automatically ends the sitz bath process.

[0016] Compared with existing technologies, the beneficial effects of this invention are as follows: This system achieves precise and stable control of the sitz bath liquid temperature by using a temperature-controlled heat-conducting liquid and a heating and temperature control module between the outer and inner tubs, combined with the closed-loop adjustment of the temperature monitoring module and the control module, thus solving the problem of excessive temperature fluctuations; the ratio adjustment module precisely controls the injection volume of medicine and water according to preset parameters, improving the ratio accuracy and avoiding concentration deviations caused by experience estimation; the liquid level detection module monitors the liquid level in real time and automatically triggers replenishment when it is below the threshold, solving the problem of incomplete liquid level management; the control module coordinates the data of each module and dynamically adjusts them to form a real-time feedback adjustment mechanism, ensuring the coordinated stability of temperature, ratio, and liquid level, greatly improving the safety and effectiveness of nursing care, while retaining the hygienic advantage of single use.

Detailed Implementation

[0019] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the disclosure to those skilled in the art. It should be noted that, unless otherwise specified, embodiments and features in the embodiments of the present invention can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0020] Reference Figure 1 , Figure 3 and Figure 4 As shown in some embodiments of this application, a temperature monitoring and proportioning sitz bath system based on disposable use includes: a double-layer sitz bath tub including an inner tub 100 and an outer tub 200, a temperature monitoring module 300, a proportioning adjustment module 400, a liquid level detection module 500, a heating and temperature control module 600, and a control module.

[0021] Specifically, the inner tub 100 is used to contain the sitz bath liquid; the outer tub 200 is fixed to the lower surface of the top of the inner tub 100, forming a sealed space between the outer tub 200 and the inner tub 100, in which a temperature-controlled heat-conducting liquid is placed; a temperature monitoring module 300 is installed on the inner wall of the inner tub 100, and is used to collect the temperature data of the sitz bath liquid in the inner tub 100 in real time; a proportioning adjustment module 400 is connected to an external medicine storage container and a water source, and is used to control the injection volume of medicine and water according to preset proportioning parameters to dispense the sitz bath liquid into the inner tub 100; and a liquid level detection module 500 is installed on the inner wall of the inner tub 100, and is used to monitor the liquid level in the inner tub 100. The heating and temperature control module 600 is embedded in the inner wall of the outer tub 200. The heating and temperature control module 600 is in contact with the temperature-controlled heat transfer fluid in the sealed space. The heating and temperature control module 600 is used to heat and control the temperature of the temperature-controlled heat transfer fluid. The control module is electrically connected to the temperature monitoring module 300, the proportioning adjustment module 400, the liquid level detection module 500, and the heating and temperature control module 600. The control module is used to receive the temperature data of the inner tub 100 collected by the temperature monitoring module 300. When the temperature data exceeds the preset range, the heating and temperature control module 600 adjusts the temperature of the temperature-controlled heat transfer fluid to correct the temperature of the sitz bath liquid. At the same time, it receives the liquid level data of the liquid level detection module 500. When the liquid level is lower than the preset threshold, the proportioning adjustment module 400 is triggered to replenish the sitz bath liquid to the inner tub 100.

[0022] Understandably, the double-layer structure design of the inner tub 100 and outer tub 200, along with the indirect temperature control method using the temperature-controlled heat-conducting liquid, combined with the real-time data collection by the temperature monitoring module 300 and the precise adjustment by the control module linked to the heating and temperature control module 600, effectively maintains a stable sitz bath liquid temperature. Furthermore, the precise control of the ratio of medicine to water by the proportioning module 400 according to preset parameters, coupled with the real-time monitoring of the liquid level by the liquid level detection module 500 and the automatic replenishment mechanism triggered by the control module, ensures that the liquid concentration and level remain within a suitable range. Overall, this achieves intelligent and coordinated control of temperature, proportion, and liquid level during the sitz bath process, significantly improving the accuracy, safety, and convenience of the care.

[0023] In a specific embodiment of this application, the above steps are implemented as follows: The inner tub 100 is made of disposable medical-grade PP material with a capacity of 5L, used to hold the sitz bath solution prepared according to the specified ratio; the outer tub 200 is made of heat-resistant ABS material, and its top is fixed to the lower surface of the top of the inner tub 100 by ultrasonic welding, forming a sealed space into which 500ml of thermally conductive silicone oil is injected as a temperature-controlled heat-conducting fluid, utilizing the stable thermal conductivity of the silicone oil to achieve uniform temperature control. The temperature monitoring module 300 uses an NTC thermistor sensor, embedded in the inner wall of the inner tub 100 5cm from the bottom, to collect the liquid temperature in real time at a frequency of 1 second / time, with a data accuracy of ±0.5℃; the ratio adjustment module 400 is connected to an external 100ml medicine bottle and a tap water interface through a food-grade silicone tube, and has a built-in miniature solenoid valve and flow meter, accurately controlling the single injection volume according to the user-set 1:10 medicine ratio (e.g., 10ml medicine to 100ml water), with an error ≤2ml. The liquid level detection module 500 uses an infrared photocell sensor, which is installed on the inner wall of the inner tank 100 at heights corresponding to 1.5L (preset lower limit of liquid level) and 3L (preset upper limit of liquid level). It monitors the liquid level through the principle of infrared reflection. The heating and temperature control module 600 is a 200W flexible heating element, which is embedded in the inner wall of the outer tank 200 and completely adheres to the thermally conductive silicone oil. It uses PWM pulse width modulation technology to adjust the power. The control module uses an STM32F103 microcontroller as its core, pre-stores a target temperature range of 38-42℃ and a liquid level range of 1.5-3L. When the temperature monitoring module 300 detects that the liquid temperature is below 38℃ or above 42℃, the microcontroller outputs a signal to adjust the heating element power (power range 50-200W), indirectly correcting the liquid temperature in the inner tub 100 through silicone oil. When the liquid level detection module 500 detects that the liquid level is below 1.5L, it triggers the proportioning module 400 to automatically replenish the liquid according to the preset proportion until the liquid level rises back to the standard position of about 2L, realizing automated temperature control and liquid level maintenance throughout the sitz bath process.

[0024] The above scenarios are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

[0025] Specifically, a protective pad is provided on the top edge of the inner tub 100, and a pressure sensor is provided on the inside of the protective pad. The pressure sensor is linked with the temperature monitoring module 300. The temperature monitoring module 300 is triggered to enter the high-frequency monitoring mode based on the pressure sensing signal received by the control module. The pressure sensor inside the protective pad is electrically connected to the control module and the temperature monitoring module 300 respectively.

[0026] Specifically, the protective pad is made of medical-grade silicone material with a thickness of 2cm. It is designed in a ring shape to fit the top edge of the inner barrel 100. Four distributed thin-film pressure sensors are embedded inside the pad. The sensors have an accuracy of ±5g and a sampling frequency of 10Hz. The pressure sensors are electrically connected to the I / O interface of the control module and the trigger terminal of the temperature monitoring module 300 through shielded wires to form a closed loop of signal transmission.

[0027] Understandably, the pressure sensor within the protective pad, along with the control module and temperature monitoring module 300, enables real-time sensing of the user's usage status. When the user's buttocks contact the protective pad, the pressure sensor detects a pressure value exceeding a preset threshold of 500g, immediately converting the pressure signal into an electrical signal and transmitting it to the control module. Simultaneously, it triggers the temperature monitoring module 300 to switch from a normal monitoring mode (1 time / second) to a high-frequency monitoring mode (10 times / second). This dynamic switching mechanism accurately captures temperature changes during user use, avoiding ineffective high-frequency monitoring during non-use periods. This improves energy efficiency and ensures accurate temperature control during user contact with liquids. The distributed layout of the pressure sensors reduces single-point force deviation, ensuring accurate recognition of user actions such as sitting down and standing up. When the detected pressure value is below 100g, the control module delays for 5 seconds before instructing the temperature monitoring module 300 to return to normal mode, forming an intelligent response chain of "use trigger - high-frequency monitoring - departure reset". Through this collaborative mechanism, the system can specifically enhance the temperature monitoring density during the user's usage phase, providing more timely feedback data for the real-time adjustment of the heating and temperature control module 600, thereby effectively preventing discomfort or scalding risks caused by temperature fluctuations, and further improving the safety and adaptability of the sitz bath process.

[0028] Specifically, when the temperature monitoring module 300 enters the high-frequency monitoring mode, it includes: the temperature monitoring module 300 collects the temperature of the sitz bath liquid in real time, presets a target temperature range, and defines a first temperature difference interval and a second temperature difference interval; the control module compares the real-time temperature with the target temperature and calculates the temperature difference: when the real-time temperature is within the target temperature range, it determines that the temperature is stable, and the control module sends a command to the heating and temperature control module 600 to maintain the current power; when the real-time temperature is lower than the lower limit of the target temperature or higher than the upper limit of the target temperature: if the temperature difference is within the first temperature difference interval, the control module sends a command to the heating and temperature control module 600 to adjust the power to the first power; if the temperature difference is within the second temperature difference interval, the control module sends a command to the heating and temperature control module 600 to adjust the power to the second power; wherein, the first power is less than the second power.

[0029] Specifically, after the heating and temperature control module 600 adjusts its power, it also includes: a temperature monitoring module 300 continuously collecting the temperature of the sitz bath liquid and setting a preset retest temperature range, wherein the fluctuation range of the retest temperature is less than the fluctuation range of the target temperature; the control module compares this temperature with the retest temperature range to determine whether the temperature adjustment has achieved precision and stability: when the temperature is within the retest temperature range, it is determined that the temperature adjustment has achieved precision and stability, and the control module sends a constant temperature maintenance command to the heating and temperature control module 600; when the temperature is not within the retest temperature range, the control module generates a fine adjustment command, controlling the heating and temperature control module 600 to perform step-by-step power fine-tuning in units of the third power; wherein the third power is less than the first power.

[0030] Specifically, after the heating and temperature control module 600 performs step-by-step power fine-tuning, it also includes: a liquid level detection module 500 that synchronously collects the liquid level of the sitz bath and presets a liquid level range; the control module compares the current liquid level with the preset liquid level range to determine whether the liquid level is in the preset state: when the liquid level is within the preset liquid level range, the current liquid level is maintained; when the liquid level is lower than the preset lower limit, the control module sends a liquid level calibration command to the proportioning adjustment module 400 to control the injection of a small amount of liquid to adjust the liquid level to the preset liquid level range.

[0031] Specifically, after the proportioning adjustment module 400 adjusts the liquid level, it also includes: the temperature monitoring module 300 re-collecting the temperature of the sitz bath liquid, and the liquid level detection module 500 collecting the adjusted liquid level; the control module calculating the temperature fluctuation value and the liquid level deviation value, and preset the temperature fluctuation threshold and the liquid level deviation threshold; when the temperature fluctuation value is less than or equal to the temperature fluctuation threshold and the liquid level deviation value is less than or equal to the liquid level deviation threshold at the same time, it is determined that the temperature and liquid level coordinated adjustment has met the standard, and the control module records the current parameters; when the temperature fluctuation value is greater than the temperature fluctuation threshold or the liquid level deviation value is greater than the liquid level deviation threshold, the control module triggers the proportioning adjustment module 400 to replenish the liquid according to half of the preset proportion, and adjusts the temperature and liquid level again until the temperature fluctuation value is less than or equal to the temperature fluctuation threshold and the liquid level deviation value is less than or equal to the liquid level deviation threshold at the same time.

[0032] Specifically, after the proportioning adjustment module 400 replenishes the liquid, it also includes: the control module comprehensively analyzes the real-time data of the temperature monitoring module 300 and the liquid level detection module 500, calculates the system adjustment compliance rate, and presets the compliance threshold; when the compliance rate is greater than or equal to the compliance threshold, it is determined that the system has completed one adjustment cycle and entered a stable operating state; when the compliance rate is less than the compliance threshold, the control module generates a readjustment command and restarts the entire process of adjustment from high-frequency temperature monitoring to proportion fine-tuning.

[0033] Specifically, the high-frequency monitoring mode of the temperature monitoring module 300 achieves "precise response" and "efficiency balance" in temperature regulation by preset target temperature range and two-level temperature difference intervals, combined with the control module's graded adjustment of heating power (the first power corresponds to a small temperature difference, and the second power corresponds to a large temperature difference). The re-inspection mechanism and stepped fine-tuning (the third power is less than the first power) of the heating and temperature control module 600 achieve secondary precise calibration by narrowing the temperature fluctuation range, forming a dual-layer temperature control logic of "coarse adjustment + fine adjustment". The linkage between the liquid level detection module 500 and the ratio adjustment module 400 maintains the stability of the range by quantitatively replenishing the liquid when the liquid level is below the lower limit, avoiding abnormal liquid level from affecting the nursing experience.

[0034] Understandably, through the collaborative verification mechanism of temperature and liquid level, the control module makes dual judgments on the deviation values ​​of the two, ensuring that the parameters meet the standards after a single adjustment, while avoiding new deviations caused by excessive intervention through gradual adjustment with half-dose supplementation. The calculation of the system's adjustment compliance rate and the full-process restart mechanism further construct an intelligent control chain of "monitoring-adjustment-verification-closed loop": high-frequency monitoring ensures real-time performance, graded adjustment balances speed and accuracy, collaborative verification ensures parameter stability, and the compliance rate judgment provides quantitative assurance for system reliability. This multi-level, full-process control logic not only achieves high-precision control of temperature ±0.5℃ and liquid level ±0.2L, but also reduces human operation errors through automated collaborative adjustment, adapting to the stringent requirements of temperature and liquid level stability in scenarios such as post-procedure surgery and gynecological care, significantly improving the safety, comfort, and intelligence level of the sitz bath process.

[0035] In a specific embodiment of this application, the above steps are implemented as follows: In practical applications, when a user sits down and the pressure sensor of the protective pad detects 800g of pressure, the temperature monitoring module 300 immediately switches from the normal mode (1 sample / second) to the high-frequency monitoring mode (5 samples / second). The preset target temperature range is 38-42℃, the first temperature difference range is ±1℃ (i.e., 37-38℃ or 42-43℃), and the second temperature difference range is ±2℃ or higher (i.e., ≤36℃ or ≥44℃). The control module (using an STM32 microcontroller) calculates the temperature difference in real time: when the temperature is between 38-42℃, it sends a command to the heating and temperature control module 600 to maintain the current 50W power; if the temperature difference is in the first range (e.g., 37.5℃ or 42.5℃), it adjusts to the first power of 100W; if the temperature difference is in the second range (e.g., 36℃ or 45℃), it activates the second power of 200W, indirectly controlling the temperature through the heat-conducting liquid in the outer tub 200. After the heating and temperature control module 600 adjusts its power, the temperature monitoring module 300 continuously collects data at a frequency of 5 times / second, with a preset retest temperature range of 39-41℃ (fluctuation range less than the target range). If the temperature is within this range (e.g., 40℃), it is determined to be accurate and stable, and maintains a constant temperature power of 80W; if the temperature is 38.5℃ (outside the retest range), it performs step-by-step fine-tuning in units of 30W (e.g., reducing from 100W to 70W). After the temperature fine-tuning is completed, the liquid level detection module 500 synchronously collects the liquid level, with a preset range of 1.5-3L. When the liquid level is 1.4L (below the lower limit), the control module sends a command to the ratio adjustment module 400 to inject 200ml of mixed solution (20ml of medicine + 180ml of water) at a 1:10 ratio until the liquid level rises back to 2L. After the proportioning adjustment module 400 adjusts the liquid level, the temperature monitoring module 300 collects the temperature again (e.g., from 39℃ to 38.8℃), and the liquid level detection module 500 records the current liquid level (2.1L). The control module calculates the temperature fluctuation value of 0.2℃ (less than the threshold of 0.5℃) and the liquid level deviation value of 0.1L (less than the threshold of 0.2L), determines that the synergistic standard is met, and records the parameters; if the liquid level deviation is 0.3L (greater than the threshold), the proportioning adjustment module 400 is triggered to replenish at half the dose (10ml of medicine + 90ml of water) and adjust again. After replenishing the liquid, the control module counts the 4 times that meet the standard out of 5 adjustments, calculates the compliance rate of 80% (reaching the preset threshold of 80%), and determines that the adjustment cycle is complete and the system has entered a stable state; if only 1 out of 3 adjustments meets the standard (compliance rate of 33%), the entire process from high-frequency monitoring to proportion fine-tuning is restarted. Through this embodiment, the system achieves precise control of temperature ±0.5℃ and liquid level ±0.2L, adapting to the stringent requirements for temperature and liquid level stability in scenarios such as postoperative care of anorectal diseases.

[0036] The above scenarios are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

[0037] Reference Figure 2 and Figure 5 As shown, the system also includes an interaction module 700, which is located on the outer wall of the outer tub 200. The interaction module 700 includes a touch button 710 and a display screen 720. The interaction module 700 is electrically connected to the control module. The interaction module 700 is used to receive parameters input by the user, such as the target temperature, sitz bath duration, and medicine solution ratio, and to display the current system operating status.

[0038] Specifically, the touch buttons 710 of the interaction module 700 adopt a waterproof capacitive design and include three function keys: "Temperature Adjustment," "Duration Setting," and "Ratio Selection." The button travel is ≤0.5mm, and the response time is ≤0.2 seconds. The display screen 720 is a 2.4-inch TFT LCD screen with a resolution of 320×240. It supports white backlighting and can display the current temperature (accurate to 0.1℃), remaining time, drug ratio (e.g., 1:10), and system status icons (e.g., "Heating" and "Stable Operation"). The interaction module 700 is connected to the I / O interface of the control module via a 24V DC line, with a data transmission rate of 9600bps, ensuring the real-time nature of parameter input and status feedback. Understandably, through the electrical connection between the touch button 710 and the control module, users can independently set target parameters according to their medical needs (such as 38℃ after anorectal surgery and 40℃ for gynecological care). The waterproof design of the button is suitable for humid environments, avoiding the risk of accidental touch or short circuit. The display screen 720 synchronizes the dynamic data processed by the control module in real time, allowing users to intuitively grasp the temperature adjustment progress, liquid level status, and remaining time, solving the problem of opaque parameters in traditional sitz bath devices. The two work together to form an "input-feedback" closed loop: after the user inputs parameters, the display screen 720 immediately displays a comparison between the set value and the current value. After confirmation, the control module executes the command and updates the status synchronously, ensuring the operation is visualized. This interactive mechanism not only meets the requirements of parameter accuracy in medical scenarios but also improves usability by simplifying the operation process (e.g., Elderly users can quickly get started), while the transparent status display enhances user trust in the system, providing operational assurance for safe sitz baths.

[0039] Specifically, the system also includes a reminder module 800, which is electrically connected to the control module. The reminder module 800 includes an audible and visual alarm and a vibration unit, used to trigger reminders in the following scenarios: when the sitz bath liquid temperature reaches the target temperature, a first prompt sound is emitted accompanied by a flashing green light; when the liquid level is lower than the minimum value of the preset liquid level range or higher than the maximum value of the preset liquid level range, a second prompt sound is emitted accompanied by a flashing red light; when the sitz bath duration reaches the preset time, a third prompt sound is emitted and the vibration unit is activated; when the system adjustment fails to reach the target threshold three times in a row, a fault prompt sound is emitted and a fault code is displayed on the display screen 720 of the interaction module 700.

[0040] Specifically, the audible and visual alarm of the reminder module 800 adopts a combination design of a buzzer and LED lights, and the vibration unit is a built-in miniature vibration motor. All three are connected to the signal output terminal of the control module through a control wiring harness. The first prompt tone is a short buzzer at a frequency of 1kHz (lasting 0.5 seconds, with a 1-second interval), accompanied by a green LED flashing 3 times / second; the second prompt tone is a long beep at a frequency of 2kHz (lasting 2 seconds, with a 0.5-second interval), which simultaneously triggers a red LED to stay lit; the third prompt tone is an intermittent buzzer at a frequency of 1.5kHz (lasting 1 second, with a 1-second interval), which is linked to the vibration unit to vibrate at a frequency of 2 times / second; the fault prompt tone is a mixed frequency buzzer (lasting 3 seconds, playing in a loop), and at the same time, the display screen 720 generates a series of codes "E01-E03" corresponding to different adjustment fault types. Understandably, through the differentiated design of multimodal reminder methods, the system can deliver accurate information for different scenarios: Temperature reachability prompts use a low-interference combination of sound and light, informing users that they can begin their sitz bath while avoiding excessive disturbance; abnormal liquid levels are indicated by a strong, continuous beep and a red light, forcibly reminding users to address the liquid level issue and prevent the risk of dry burning or overflow; when the sitz bath time is up, the vibration unit and buzzer work together to ensure user awareness even in noisy environments, preventing skin discomfort caused by prolonged sitz baths; fault prompts use coded displays and special sound effects to help users or maintenance personnel quickly locate the type of problem (such as temperature regulation failure, mixing module malfunction, etc.). This tiered reminder mechanism relies on the signal logic judgment of the control module to achieve precise matching of "scenario-intensity-method," ensuring the effective transmission of key information while reducing invalid interference through differentiated design. This forms a closed-loop reminder process from preparation to fault handling, further enhancing the system's safety and user-friendliness, especially suitable for the needs of elderly patients or people with mobility impairments.

[0041] Specifically, the interaction module 700 and the reminder module 800 work together. When the reminder module 800 is triggered, the user can perform a confirmation operation through the touch button 710 of the interaction module 700. After confirmation, the reminder module 800 stops reminding. If no confirmation is received within ten seconds, the reminder module 800 will increase the reminder intensity until the user confirms or the system automatically ends the sitz bath process. The confirmation button is a long press duration setting button.

[0042] Understandably, this interconnected design, through a tiered "trigger-response-reinforcement" mechanism, ensures users' effective perception of key states (such as temperature reaching the target or timeout). The physical interaction of the touch button 710 and the visual feedback of the display screen 720 form a dual confirmation channel, adapting to the perceptual habits of different users. The 10-second timeout reinforcement logic targets elderly or mobility-impaired users, preventing reminders from failing due to delayed responses. Simultaneously, the automatic process termination setting establishes a safety fallback mechanism, preventing resource waste or safety risks caused by the system's continued operation when unattended. Through deep collaboration between interaction and reminders, the system forms a complete closed loop of "status reminder - user confirmation - anomaly reinforcement - safety termination," improving both operational convenience and safety, especially suitable for the stringent requirements of process standardization in medical and nursing scenarios.

[0043] In a specific embodiment of this application, the above steps are implemented as follows: The touch button 710 area of ​​the interaction module 700 is located in the middle of the outer wall of the outer barrel 200, and includes three independent touch buttons: "Temperature Adjustment" button, "Duration Setting" button, and "Ratio Selection" button. All of them adopt capacitive touch sensing design, with a trigger pressure ≤50g and a response time ≤0.5 seconds; the display screen 720 is a 2.4-inch LCD screen with a resolution of 320×240, which displays the current temperature, remaining time, drug ratio, and reminder status in real time. When the reminder module 800 is triggered, the linkage mechanism works as follows: If the sitz bath liquid reaches the preset target temperature of 40℃, the reminder module 800 emits a 300Hz first prompt tone (lasting 1 second, with a 2-second interval), accompanied by a green LED flashing twice per second. At this time, if the user touches any of the "Temperature Adjustment," "Duration Setting," or "Ratio Selection" buttons, the display screen 720 will pop up a "Temperature Target Achieved" confirmation box, which will automatically close after 2 seconds, and the reminder module 800 will stop working simultaneously. If no button is pressed within 10 seconds, the prompt tone frequency increases to 500Hz, the green light flashes more frequently to 4 times per second, and the vibration unit (built into the interaction module 700) starts a slight vibration (amplitude). (0.5mm, frequency 2Hz); When the sitz bath time reaches the preset 15 minutes, the third prompt tone (600Hz, lasting 2 seconds) and the vibration unit (amplitude 1mm, frequency 3Hz) are activated synchronously. After the user touches any button, the display screen 720 shows a 5-second countdown to "Ending Soon," and then automatically shuts off the heating and adjustment functions. If the system fails to meet the standard after three consecutive adjustments, a fault prompt tone (1000Hz, lasting 3 seconds) will sound, the red LED will stay on, and the display screen 720 will display the fault code "E03." The user needs to touch the "Ratio Selection" button to confirm; otherwise, the prompt tone intensity will increase by 30% after 10 seconds until confirmation or the system automatically cuts off the power (default 1 minute). Through the three-button linkage design, the independent parameter adjustment function of each button is retained, while the convenient operation of reminder confirmation is realized, adapting to the operating habits of different users (such as the elderly and postoperative patients), ensuring the timeliness and reliability of the reminder response.

[0044] When the reminder module is triggered (e.g., when the temperature reaches the target, the duration ends, or the liquid level is abnormal), the user can confirm the action by touching any of the three buttons. After confirmation, the reminder module will stop reminding (e.g., the notification sound, light, and vibration will all stop), and the interactive module's display screen will simultaneously show confirmation feedback (e.g., a corresponding prompt box will pop up).

[0046] In the above embodiments, the temperature-controlled heat-conducting liquid between the outer tub 200 and the inner tub 100, along with the heating and temperature control module 600, combined with the closed-loop adjustment of the temperature monitoring module 300 and the control module, achieves precise and stable control of the sitz bath liquid temperature, solving the problem of excessive temperature fluctuations. The ratio adjustment module 400 precisely controls the injection volume of medicine and water according to preset parameters, improving the ratio accuracy and avoiding concentration deviations caused by experience estimation. The liquid level detection module 500 monitors the liquid level in real time and automatically triggers replenishment when it is below the threshold, solving the problem of missing liquid level management. The control module coordinates the data of each module and dynamically adjusts them to form a real-time feedback adjustment mechanism, ensuring the coordinated stability of temperature, ratio, and liquid level, greatly improving the safety and effectiveness of nursing care, while retaining the hygienic advantage of single use.
