Description

Technical Field

[0001] This invention relates to the field of medical environment control technology, and in particular to a precise temperature control system and method for a clean operating room that utilizes radiative cooling. Background Technology

[0002] With advancements in medical technology and increasing patient safety demands, the impact of operating room temperature control on surgical success rates and postoperative recovery is becoming increasingly prominent. While traditional air conditioning systems maintain a sterile environment in the surgical area, improper airflow organization often leads to temperature imbalances between the medical staff's work area and the surgical area. This can cause thermal discomfort for medical staff during prolonged surgeries, while increasing the risk of intraoperative hypothermia in patients due to anesthetic metabolic suppression. Therefore, how to simultaneously meet the thermal comfort needs of medical staff and maintain stable core body temperatures for patients while ensuring operating room cleanliness has become a critical issue that urgently needs to be addressed in the field of clean operating room temperature control.

[0003] Currently, research on temperature control systems for clean operating rooms is lacking, and existing systems exhibit significant technical deficiencies. Traditional temperature control methods primarily achieve this by altering the temperature of the air supply outlets. However, this is affected by factors such as airflow diffusion speed and delays in indoor heat exchange, resulting in poor temperature regulation accuracy, slow response, and lag, making it impossible to match dynamic heat load changes within the operating room in real time. Furthermore, to ensure air cleanliness in the surgical area, traditional clean operating rooms typically place air supply outlets directly above the operating table, with minimum air intake limits to meet cleanliness requirements. Since patient body temperature primarily depends on the temperature of the fresh air supplied through these outlets, the outlet temperature settings must prioritize patient needs, failing to simultaneously meet the thermal needs of both medical staff and patients. Additionally, medical equipment such as shadowless lamps, medical air supply devices, and film viewing lights continuously generate heat during operation, leading to localized heat accumulation. Existing systems, to prevent patient hypothermia, require strict temperature limits on the air supply outlets, hindering effective heat dissipation from the equipment. This not only shortens the lifespan of medical equipment but also further increases the perceived temperature for medical staff, reducing their comfort. Summary of the Invention

[0004] The purpose of this invention is to provide a precise temperature control system and method for clean operating rooms that utilizes radiative cooling. By using a temperature equalization plate radiative cooling technology coupled with dynamic feedback regulation, it can achieve precise and rapid control of the air temperature in different areas inside the clean operating room, the perceived temperature of medical staff inside the operating room, and the patient's body temperature, thereby improving the comfort of medical staff inside the clean operating room and reducing the occurrence of hypothermia during and after surgery.

Step S2: Start the clean air circulation system, set the supply air temperature and supply air speed, and maintain a constant supply air volume; start the constant temperature air circulation system, and set the initial inlet air temperature and initial inlet air speed of the fan in the area-level subsystem. Step S3: The sensor unit collects the body surface temperature of medical staff, the surface temperature of medical equipment and indoor humidity in real time to obtain the real-time heat load value. The location unit determines the spatial area where the medical staff and medical equipment are located in real time to obtain the real-time location information. The real-time heat load value and real-time location information are transmitted to the data receiving unit of the dynamic intelligent control module. Step S4: The data receiving unit obtains the temperature of the zone based on the real-time heat load value, determines the target temperature of the zone, and transmits the target temperature to the control unit of the dynamic intelligent control module. Step S5: The control unit performs dynamic adjustment, calculates the target inlet air temperature and target inlet air velocity of the fan, and transmits the calculation results to the execution unit; Step S6: The execution unit adjusts the inlet air temperature and inlet air speed of the fan according to the calculation results, so that the temperature of the zone reaches the target temperature and radiative heat exchange occurs between the fan and medical staff and medical equipment.

[0020] The technical solution of the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Unless otherwise defined, the technical or scientific terms used in this invention shall have the ordinary meaning as understood by one of ordinary skill in the art to which this invention pertains.

[0022] Example 1 like Figure 1 As shown, the present invention provides a precise temperature control system for a clean operating room using radiative cooling, including a temperature equalization plate module, a constant temperature air circulation system module, a clean air circulation system module, a detection module, and a dynamic intelligent control module. The heat spreader module is a high-emissivity hollow plate structure containing a hollow cavity. It is installed on the inner wall of the operating room. The hollow plate of the heat spreader has a high emissivity. The vapor chamber is divided into four zones: the surgeon's zone, the assistant's zone, the anesthesiologist's zone, and the instrument station zone. Each zone's hollow cavity is independently connected to the air outlet of a fan in a regional subsystem. During operation, the vapor chamber module maintains a stable surface temperature by convective heat exchange within the hollow chamber through constant-temperature air. Due to the temperature difference between the medical staff's body surface, the medical equipment surface, and the vapor chamber surface, heat is transferred to the vapor chamber through thermal radiation, achieving localized cooling.

[0023] The constant temperature air circulation system module includes operating room-level subsystem units and area-level subsystem groups. The operating room-level subsystem unit includes a fresh air handling unit and a purification air conditioning unit. The area-level subsystem group unit includes at least one area-level subsystem, which includes a fan. The purification air conditioning units of the operating room-level subsystem units are set according to the operating room level. Class I clean operating rooms, Class II clean operating rooms and negative pressure operating rooms use one purification air conditioning unit independently. Class III clean operating rooms and Class IV clean operating rooms can share one purification air conditioning unit for 2-3 rooms. The fresh air intake velocity of the fresh air handling unit in the operating room subsystem The exhaust volume of a positive pressure operating room The design unit air volume power consumption of the fresh air handling unit and air conditioning unit fans in the operating room subsystem should meet the following requirements. The specific calculation formula is as follows: ; ; in, Power consumption per unit air volume For the full pressure of the fan, For the full efficiency of the wind turbine, For fan efficiency, For motor efficiency, For transmission efficiency; The regional subsystem group units meet the air temperature difference between the inlet and outlet. Internal air humidity Dust content ; The regional subsystem group can precisely adjust the air temperature and flow rate delivered to the corresponding heat exchange plate, thereby controlling the surface temperature of the heat exchange plate and providing constant temperature air support for the heat exchange plate module to achieve precise radiative heat exchange, thus improving the accuracy and response speed of temperature regulation.

[0024] The clean air circulation system module's air outlet is located directly above the operating table. During operation, the air volume and speed remain constant. The fresh air temperature is typically set at 24℃-26℃ to prevent patients from suffering hypothermia due to excessively low fresh air temperature. At the same time, it provides a basic temperature environment for the operating room. In conjunction with the temperature equalization plate module, it forms a composite temperature control mode that combines basic temperature regulation and local radiation regulation, achieving a balance between cleanliness and stable patient body temperature.

[0025] The detection module includes a sensor unit and a positioning unit, which communicate with the dynamic intelligent control module. The sensor unit includes non-contact temperature sensors, humidity sensors, and thermal sensors, which are distributed along the perimeter and height of the operating room's cubic space. The positioning unit uses visual recognition or radio frequency positioning technology to collect real-time data on the body surface temperature of medical staff, the temperature of medical equipment, indoor humidity, and the spatial area where medical staff and medical equipment are located. This provides accurate monitoring information for the dynamic intelligent control module and is the foundation for achieving dynamic adjustment.

[0026] The dynamic intelligent control module includes a data receiving unit, a control unit, and an execution unit. The execution unit is equipped with a manual control panel and is communicatively connected to the constant temperature air circulation system module. The control unit is equipped with an algorithm module that stores dynamic adjustment algorithms. The execution unit supports automatic and manual adjustment. Manual adjustment commands are input through the manual control panel. Manual adjustment has higher priority than automatic adjustment. Based on real-time monitoring data or manual commands, the module adjusts the inlet air temperature and inlet air speed of the fans in the regional subsystem group to achieve precise control and dynamic, zoned, and personalized adjustment of the surface temperature of the heat exchange plate, meeting the thermal needs of different areas.

Step S3: The sensor unit collects real-time data on the body surface temperature of medical staff, the surface temperature of medical equipment, and indoor humidity to obtain real-time heat load values. The location unit determines the spatial area where the medical staff and medical equipment are located in real-time to obtain real-time location information. The real-time heat load values ​​and real-time location information are transmitted to the data receiving unit of the dynamic intelligent control module. The sampling frequency... The body surface temperature of medical staff and the surface temperature of medical equipment are collected using non-contact infrared sensors; Step S4: The data receiving unit obtains the temperature of the zone based on the real-time heat load value, determines the target temperature of the zone, and transmits the target temperature to the control unit of the dynamic intelligent control module. Step S5: The control unit performs dynamic adjustment, calculates the target inlet air temperature and target inlet air velocity of the fan, and transmits the calculation results to the execution unit. The specific steps are as follows: Step S51: Receive the body surface temperature of medical staff and calculate the deviation of the body surface temperature of medical staff; Step S52: Calculate the temperature of the partition using an intelligent algorithm; Step S53: Receive the temperature of the zone, calculate the target inlet air temperature and target inlet air velocity of the fan, and transmit the calculation results to the execution unit; Step S6: The execution unit adjusts the inlet air temperature and inlet air speed of the fan according to the calculation results, so that the temperature of the zone reaches the target temperature and radiative heat exchange occurs between the fan and medical staff and medical equipment. The execution unit includes two modes: automatic adjustment and manual adjustment. In automatic adjustment mode, the inlet air temperature and inlet air speed of the fan are adjusted according to the calculation results of the control unit. In manual adjustment mode, the inlet air temperature and inlet air speed of the fan are adjusted according to the received manual command. Step S7: Continuously monitor the body surface temperature of medical staff, the surface temperature of medical equipment, and indoor humidity to obtain real-time changes in heat load values, and continuously and dynamically adjust the temperature of each zone until the surgery is completed.

[0028] The invention will be further illustrated below through specific implementation examples.

[0029] The specific implementation examples of this invention use ANSYS Fluent fluid dynamics simulation software.

[0030] Step S1: Set the initial temperature of the heat spreader to 26℃, and divide the heat spreader into zones, as shown in the zoning scheme. Figure 3 As shown, record the partitions of the vapor chamber; Step S2: The clean air circulation system module starts the clean air circulation system. The system air outlet is located directly above the operating table. The air supply temperature is set to 25℃ and the air supply speed is 0.3m / s, and the air supply volume is kept constant. The constant temperature air circulation system module starts the constant temperature air circulation system. The initial air supply temperature of the fan in the area-level subsystem is set to 25℃ and the air supply speed is 1.0m / s. Step S3: Utilize the non-contact infrared sensor in the sensor unit of the detection module to collect real-time data on the body surface temperature of medical personnel and the surface temperature of medical equipment; and utilize the humidity sensor to collect real-time data on indoor humidity. The sampling frequency is... The system obtains real-time heat load values; the location unit uses visual recognition or radio frequency positioning technology to determine the spatial area where medical personnel and medical equipment are located in real time, and the acquisition frequency is [not specified]. To obtain real-time location information; Based on simulation analysis, the response of medical personnel and equipment at different locations to temperature-controlled heat exchangers in different areas was determined. The results are as follows: Figure 4 As shown, the data receiving unit of the dynamic intelligent control module transmits real-time heat load and real-time location information to the module. Step S4: The data receiving unit obtains the temperature of the zone based on the real-time heat load value, determines the target temperature of the zone, and transmits the target temperature to the control unit of the dynamic intelligent control module. Step S5: The control unit performs dynamic adjustment, calculates the target inlet air temperature and target inlet air velocity of the fan, and transmits the calculation results to the execution unit. The specific steps are as follows: Step S51: Receive the body surface temperature of medical staff and determine whether the received body surface temperature is within the normal range. If it is within the normal range, return to step S2 to continue detecting the body surface temperature of medical staff; if it is not within the normal range, calculate the deviation of the body surface temperature of medical staff. Step S52: Calculate the temperature of the partition using an intelligent algorithm; Step S53: Receive the temperature of the partition, determine whether the temperature of the partition needs to be changed. If it does not need to be changed, return to step S2 to continue to detect the body surface temperature of medical staff. If it needs to be changed, calculate the target air inlet temperature and target air inlet speed of the fan, and transmit the calculation results to the execution unit. Step S6: Based on the calculation results, the execution unit adjusts the inlet air temperature and speed of the fan to bring the zone temperature to the target temperature, enabling radiative heat exchange between the zone and medical personnel and equipment. The effect of zone temperature on the radiation dose to doctors is as follows: Figure 5 As shown; The execution unit includes two modes: automatic and manual. In automatic mode, when the heat load exceeds 200W, the fan's inlet temperature is reduced and its inlet speed is increased until the vapor chamber reaches the target temperature. When the heat load drops to 180W, the fan's inlet temperature is increased and its inlet speed is reduced until the vapor chamber reaches the target temperature. In manual mode, medical staff can directly select the vapor chamber's operating status on the control panel based on their location and responsibilities. The system adjusts the fan's inlet temperature and speed according to the received manual commands. When the commands for manual adjustment conflict with those for automatic adjustment, the manual adjustment command takes precedence. Step S7: Continuously monitor the body surface temperature of medical staff, the surface temperature of medical equipment, and indoor humidity to obtain the real-time changes in heat load values. Determine whether the deviation of the body surface temperature of medical staff has decreased. If the deviation has decreased, maintain the air intake speed and air intake temperature of the fan at this time. If the deviation has not decreased, return to step S52 to continue to calculate the temperature of the zone through the intelligent algorithm. Continuously and dynamically adjust the temperature of the zone until the operation is over.

[0031] It is worth noting that all contents not described in detail in this invention are existing technologies and are well known to those skilled in the art.

[0032] Therefore, this invention provides a precise temperature control system and method for clean operating rooms utilizing radiative cooling. By real-time monitoring of the body surface temperature of medical staff in the operating room and combining thermodynamic models and algorithms to analyze the comfort needs of medical staff in different areas, the temperature parameters of the heat exchange plate are intelligently adjusted to achieve real-time control of local heat exchange of medical staff. By constructing an independent temperature control module, while dynamically adjusting the thermal environment adaptability of medical staff, the heat exchange volume of the patient's core area is maintained within the clinically safe threshold range, effectively avoiding the risk of patient body temperature imbalance caused by thermal imbalance during surgery.
