[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the implementation regulations described are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0033] Example 1: Reference Figure 2 Shown: An intelligent temperature-controlled interventional surgical insulation and shape-fitting surgical blanket solves the problem that traditional surgical blankets lack temperature regulation function, cannot respond to patient body temperature changes in real time, are difficult to maintain patient body temperature, and affect the insulation effect.

[0034] 1. System composition and core module functions.

[0035] The core of the surgical blanket is the temperature control system, which consists of a temperature acquisition module 1, a control core module 2, a heating execution module 3, a wireless communication module 4, a user interaction module 5, and a safety protection module 6. These modules work together to achieve precise temperature control, safety protection, and convenient interaction. Specific functions are as follows:

[0036] Temperature acquisition module 1: collects the temperature of each area of ​​the surgical quilt and the patient's body temperature in real time, and transmits the data to the control core module in the form of digital signals.

[0037] Control Core Module 2: Serving as the system's core, it includes submodules for receiving and comparing temperature data, power control, command generation, and data interaction. It receives temperature data, compares it with the preset target temperature range, calculates heating power using a PID control algorithm, generates control commands, and interacts with other modules.

[0038] Heating execution module 3: According to the instructions of the control core module, it controls the heating equipment (such as carbon fiber heating plate 82) to heat multiple areas of the surgical quilt component 7; if the temperature is too high, it can also be linked to the semiconductor cooling plate to cool it down.

[0039] Wireless communication module 4: supports Bluetooth (short-range communication with mobile devices in the operating room, facilitating on-site viewing / adjustment of parameters by medical staff) and Wi-Fi (real-time data upload to the hospital information management system, supporting remote monitoring and data storage and analysis).

[0040] User Interaction Module 5: Supports medical staff to set the target temperature range, view the temperature of each area, select the insulation mode, and display the system status in real time through touch operations.

[0041] Safety protection module 6: adopts dual MCU architecture (the main MCU is responsible for system operation, and the slave MCU is responsible for safety monitoring), including overheat protection, short circuit protection and abnormal alarm sub-modules to ensure system safety and reliability.

[0042] 2. Core workflow, including preoperative preparation stage, intraoperative temperature control stage, safety protection stage, and data interaction and postoperative stage.

[0043] Preoperative preparation stage: Medical staff sets the target temperature range through the user interaction module 5 (or mobile device); the system automatically performs a safety self-check to check whether the overheat protection and short-circuit protection circuits are normal.

[0044] During the intraoperative temperature control phase, temperature acquisition module 1 collects the patient's surface temperature and the temperature of various areas of the surgical drape in real time and transmits it to core control module 2. Receiving and comparison module 21 in core control module 2 compares the real-time temperature with the target temperature range. If the temperature is below the target lower limit, carbon fiber heating plate 82 in heating execution module 3 increases power through PWM control to raise the temperature. If the temperature is above the target upper limit, heating is stopped and the semiconductor cooling plate is activated to lower the temperature. Power control module 22 calculates the heating power using a PID algorithm (which requires error calculation, integral / differential term processing, and output conversion) to ensure accurate temperature control.

[0045] Security protection stage: Security protection module 6 monitors the system status throughout the entire process, including:

[0046] (1) Overheat protection: Each carbon fiber heating plate 82 / cooling plate circuit is connected in series with a high-precision temperature fuse, which automatically melts when the temperature exceeds the threshold and cuts off the circuit; at the same time, the hardware monitoring circuit triggers an emergency power-off and the system sounds and lights an alarm.

[0047] (2) Short-circuit protection: The power input terminal is integrated with a resettable fuse (PPTC). When a short circuit occurs, the PPTC enters a high-resistance state to limit the current. When the Hall current sensor detects that the current exceeds 120% of the rated value, the microcontroller cuts off the circuit output and issues an alarm.

[0048] (3) Abnormal alarm: When the system or circuit is abnormal, an alarm signal is sent to the control terminal and an alarm sound is issued to remind medical staff to deal with it.

[0049] Data Interaction and Postoperative Stage: The wireless communication module 4 uploads temperature data and safety status to the hospital information management system in real time, supporting remote monitoring and data storage. It also receives commands from mobile devices / remote terminals (e.g., modifying target temperature). After surgery, the protective surface layer 72 (waterproof and antibacterial material) of the removable surgical drape is cleaned and disinfected.

[0050] Summary of working principle:

[0051] This intelligent surgery achieves precise temperature management of surgical patients through a closed-loop process of "temperature collection - intelligent analysis - precise temperature control - safety protection - convenient interaction". Its core technical features include:

[0052] (1) Zoned temperature control and shape-fitting: The surgery is divided into multiple zones, which can be adjusted in shape according to the patient's body shape, and the carbon fiber heating sheet 82 can be used to achieve local precise temperature control;

[0053] (2) High-precision temperature control algorithm: Using PID control algorithm, the heating power is dynamically adjusted through error analysis to ensure that the temperature is stable within the target range;

[0054] (3) Double safety protection: Dual MCU architecture and hardware protection (temperature fuse, PPTC) + software monitoring (current / temperature monitoring) to fully prevent risks such as overheating and short circuit;

[0055] (4) Multi-scenario interaction capability: supports Bluetooth short-range operation, Wi-Fi remote monitoring and touch interaction, taking into account the needs of real-time adjustment during surgery and postoperative data tracing.

[0056] Example 2: Reference Figure 2 As shown: an intelligent temperature-controlled interventional surgical insulation and shapeable fitting functional surgical quilt, including a surgical quilt component 7, the surgical quilt component 7 is divided into multiple areas, and the surgical quilt component 7 is temperature-controlled based on a temperature control system, the temperature control system includes a temperature acquisition module 1, a control core module 2, a heating execution module 3, a wireless communication module 4, a user interaction module 5 and a safety protection module 6, the temperature acquisition module 1 is used to collect the temperature of the surgical quilt and the patient, and transmit the collected information to the control core module 2 in the form of a digital signal; the control core module 2 receives the temperature data transmitted by the temperature acquisition module 1, compares and calculates the data, and sends a control instruction to the heating execution module 3 according to the calculation result;

[0057] The control core module 2 includes a receiving and comparison module 21, a power control module 22, an instruction generation module 23 and a data interaction module 24. The receiving and comparison module 21 compares and analyzes the temperature data received from the temperature acquisition module 1 with the preset target temperature range; the power control module 22 calculates the required heating power through a control algorithm based on the comparison results of the receiving and comparison module 21; the instruction generation module 23 generates corresponding control instructions based on the calculation results of the power control module 22; the data interaction module 24 is responsible for data interaction with the wireless communication module 4 and the user interaction module 5.

[0058] The heating execution module 3 is used to control the heating device to heat the surgical component 7 in different zones.

[0059] The wireless communication module 4 establishes a communication channel with the mobile devices in the operating room and supports wireless communication methods such as Bluetooth and Wi-Fi. The Bluetooth module can realize short-distance communication with mobile devices near the operating room, which is convenient for medical staff to check and adjust the temperature parameters of the surgical quilt at any time during the operation. Using the Wi-Fi module, the temperature data of the surgical quilt can be uploaded to the hospital's information management system in real time. Doctors can remotely monitor the patient's body temperature changes during the operation through the hospital network in the office or other places. It also facilitates the long-term storage and analysis of the usage data of the surgical quilt.

[0060] The user interaction module 5 supports setting the target temperature range, viewing the temperature of each area of ​​the surgical quilt component 7, and selecting the insulation mode. Medical staff can set the target temperature range, view the temperature of each part of the current surgical quilt, and select different insulation modes through touch operations.

[0061] The safety protection module 6 adopts a dual-MCU architecture. The master MCU is responsible for normal system operation control, while the slave MCU is responsible for safety monitoring. The two regularly exchange status information through independent communication channels to ensure the reliability of the safety protection function.

[0062] The safety protection module 6 includes an overheat protection module 61, a short circuit protection module 62 and an abnormality alarm module 63. The overheat protection module 61 is provided with an overheat protection circuit. A high-precision temperature fuse is connected in series between each carbon fiber heating plate 82 and the cooling plate circuit. When the local temperature exceeds the safety threshold, the fuse automatically melts, cutting off the circuit to prevent continuous overheating.

[0063] The short-circuit protection module 62 is provided with a short-circuit protection circuit. A resettable fuse PPTC is integrated at the power input terminal. When a short circuit occurs in the circuit and the current increases abnormally, the PPTC automatically enters a high-resistance state to limit the current. After the fault is eliminated, it automatically resumes conduction. A Hall current sensor is used to monitor the current of each circuit in real time. When it is detected that the current exceeds 120% of the rated value, the microcontroller immediately cuts off the PWM output of the corresponding circuit and triggers an audible and visual alarm.

[0064] The abnormal alarm module 63 sends an alarm signal to the control terminal when there is an abnormality in the system operation and the temperature control circuit. The system is also equipped with a sound prompt function. When there is an abnormality in the temperature control circuit, an alarm sound is issued to remind medical staff to pay attention.

[0065] The following steps are also included in the calculation of heating power:

[0066] Step 1, PID control algorithm: According to the error between the current temperature and the target temperature, the control output proportional term, integral term and differential term are calculated through the weighted combination of three parameters.

[0067] Step 2: Heating power calculation process: define parameters, including target parameters, current temperature, proportional coefficient, integral coefficient, differential coefficient, and power limit of PID parameters; calculate error, calculate integral term, accumulate historical error when calculating integral term, calculate differential term to obtain error change rate, calculate PID output and convert it into heating power;

[0068] Step 3: PID parameter adjustment and optimization: Set the integral coefficient and differential coefficient to 0, gradually increase the proportional coefficient until the system has critical oscillation, record the critical gain and oscillation period, and calculate the initial parameters.

[0069] Example 3: Reference Figure 3-Figure 6As shown: the surgical quilt component 7 is divided into multiple areas, and the surgical quilt component 7 includes a protective surface layer 72, a heating middle layer 73 and a breathable inner layer 74. One side of the breathable inner layer 74 is compounded with the heating middle layer 73. One side of the breathable inner layer 74 is fixedly connected to a strap 71. One side of the heating middle layer 73 is fixedly connected to a Velcro 721. The protective surface layer 72 and the heating middle layer 73 are bonded by the Velcro 721. A control panel 8 is clamped on one side of the protective surface layer 72. The control panel 8 is electrically connected to a connecting end 81. One side of the connecting end 81 is embedded in the heating middle layer 73. The connecting end 81 is electrically connected to a carbon fiber heating sheet 82. The carbon fiber heating sheet 82 is embedded in the heating middle layer 73, and a filler is provided inside the heating middle layer 73. A temperature sensor 83 is embedded in the protective surface layer 72. The temperature sensor 83 is electrically connected to the control panel 8. The control panel 8 is electrically connected to a body temperature sensor 84. The top of the body temperature sensor 84 is embedded in the breathable inner layer 74.

[0070] In this embodiment, the protective surface layer 72 and the heating middle layer 73 are bonded by Velcro 721, which facilitates the installation and removal of the protective surface layer 72 on the top of the heating middle layer 73. The control panel 8 facilitates the adjustment of the heating temperature of the surgical quilt component 7, and the connection end 81 facilitates the connection of the surgical quilt component 7 with the external circuit and power supply. The filling material inside the heating middle layer 73 is memory foam or polymer material. The body temperature sensor 84 is embedded in the breathable inner layer 74, which facilitates the contact of multiple body temperature sensors 84 with different parts of the patient's body to detect the temperature change of the patient's body. Before the operation, the surgical quilt component 7 is covered with Covering the patient's torso, the surgical quilt assembly 7 is divided into multiple areas when suturing. The various parts of the surgical quilt assembly 7 can be adjusted during use to adjust the surgical quilt assembly 7 to a suitable shape so that the surgical quilt assembly 7 fits the torso of patients of different sizes. During the operation, the temperature is collected in real time by the temperature acquisition module 1 in the control system, and the temperature is adjusted by the control core module 2 and the heating execution module 3. After the operation, the protective surface layer 72 can be removed from the top of the heating middle layer 73 for cleaning and disinfection. The protective surface layer 72 is made of waterproof and antibacterial fabric, and the breathable inner layer 74 is made of skin-friendly fabric.

[0071] The working principle of the present invention is as follows: first, before the operation, the medical staff sets the target temperature range of the surgical quilt by touching the display screen of the control panel 8 or a mobile device. Generally, the normal body temperature range of the human body is 36°C-37.2°C, which can be fine-tuned according to the specific situation of the patient. At the same time, the system automatically performs a safety self-check to check whether the overheat protection and short-circuit protection circuits are working properly. During the operation, the temperature acquisition module 1 collects the patient's body surface temperature data in real time and transmits the data to the control core module 2. The safety protection module 6 synchronously monitors the temperature and current data of each circuit. The control core module 2 compares the collected temperature data with the preset target temperature range. If the temperature is lower than the lower limit of the target range, the control core module 2 sends an instruction to the carbon fiber heating plate 82 in the heating execution module 3, and increases the heating power through PWM control of the temperature sensor 83 to increase the temperature of the surgical quilt; if the temperature is higher than the upper limit of the target range, the control core module 2 stops the operation of the heating execution module 3 and sends an instruction to the external semiconductor refrigeration chip to adjust the working current of the refrigeration chip to enhance the refrigeration effect and reduce the temperature of the surgical quilt;

[0072] The safety protection module 6 continuously monitors the system status. When the temperature of a certain area exceeds the overheat protection threshold, the temperature fuse of the area will melt, and the hardware monitoring circuit will trigger an emergency power off. The microcontroller will cut off the power supply of the circuit after receiving the fault signal, and send out an audible and visual alarm through the user interaction module 5. When an abnormal increase in the circuit current is detected, the microcontroller will immediately stop the PWM output of the circuit, and the self-resetting fuse will enter a high-resistance state to limit the current. At the same time, the system alarm will indicate a short circuit fault.

[0073] The control core module 2 continuously adjusts the heating power according to the data feedback from the temperature acquisition module 1, and works in conjunction with the safety protection module 6 to ensure that the system operates within a safe range, so that the temperature of the surgical quilt is always maintained within the preset target temperature range, thereby achieving precise control of the patient's body temperature. During the entire process, the wireless communication module 4 uploads the temperature data and safety status of the surgical quilt to the hospital information management system in real time, and at the same time receives instructions from mobile devices or remote terminals, such as modifying the target temperature, and conveys the instructions to the control core module 2. The user interaction module 5 displays the temperature information, working status and operation status of the surgical quilt in real time, and issues a sound alarm when the temperature is abnormal or a safety failure occurs, reminding medical staff to deal with it in time.

[0074] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
