[0002] Environmental control of surgical clean rooms is an important part of medical facilities. The operating room environment not only needs to maintain cleanliness, but also requires precise control of temperature and humidity. A suitable temperature and humidity environment helps to ensure the smooth progress of the operation, maintain the patient's body temperature, and provide a comfortable working environment for medical staff.

[0003] At present, the temperature and humidity control of clean rooms is mainly achieved by constant temperature and humidity air conditioning systems. Before the operation begins, the staff sets the temperature and humidity at a predetermined value according to the operation requirements, and the system maintains the set value stable through automatic control devices. However, since the operation process often lasts for a long time and the requirements for the environment at different stages of the operation are different, the fixed temperature and humidity setting values ​​may not meet the actual needs of the entire operation process, affecting the overall control effect of the clean room temperature and humidity.

This dynamic adjustment method based on the actual situation of the surgical process not only overcomes the problem that the fixed temperature and humidity setting values ​​cannot meet the needs of different surgical stages, but also can adjust the environmental parameters in time according to the changes in the operating status of the surgical equipment and the physiological condition of the patient, thereby improving the accuracy and adaptability of clean room temperature and humidity control.

[0016] The following will provide a clear and complete description of the technical solutions in the embodiments of the present application in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

[0017] Please refer to Figure 1 , a flow chart of a clean room control method with constant temperature and humidity function is proposed. The method can be implemented by a computer program, can be implemented by a single-chip microcomputer, or can be run on a clean room control system with constant temperature and humidity function. The computer program can be integrated in a computer device or can be run as an independent tool application. Specifically, the method includes steps 10 to 40, and the above steps are as follows: Step 10: Determine the initial environmental parameters of the clean room based on the surgery reservation information, and adjust and control them according to the initial environmental parameters within a preset time before the surgery.

[0018] Among them, the surgery appointment information in the embodiment of the present application refers to pre-stored surgery information, including but not limited to basic information related to the surgery, such as surgery type, surgery site, and estimated surgery time.

[0019] In the embodiment of the present application, the initial environmental parameters of the clean room refer to environmental control parameters such as temperature and humidity that need to be pre-set and regulated before the operation begins. These parameters are determined based on the operation reservation information and serve as the initial state of the clean room environment when the operation begins.

[0020] Specifically, since different types and parts of surgery have different environmental requirements, it is necessary to pre-set appropriate environmental parameters according to the surgery reservation information. The surgery reservation information can be obtained from the hospital's surgery management system, which includes basic information such as surgery type, surgery site, and expected surgery time. Based on the preset environmental parameter database, the acquired surgery type is matched with the surgery type in the database to obtain the corresponding reference temperature; at the same time, the corresponding reference humidity is queried from the database according to the surgery site information. The obtained reference temperature and reference humidity are combined to form the initial environmental parameters of the clean room. After determining the initial environmental parameters, the system will start the constant temperature and humidity air conditioning system within the preset time before the start of the surgery (for example, 1 hour in advance) and regulate the clean room according to the set initial environmental parameters. This pre-regulation method enables the clean room environment to stabilize at a suitable temperature and humidity state before the start of the surgery, avoiding the problem of temporarily adjusting the environmental parameters at the start of the surgery and affecting the surgical process, and also provides good initial conditions for subsequent dynamic adjustment according to the actual situation during the operation.

[0021] Based on the above embodiment, as an optional embodiment, the step of determining the initial environmental parameters of the clean room according to the surgery reservation information may further include the following steps: Step 101: Obtain the operation type and operation site information in the operation reservation information.

[0022] Specifically, the system obtains surgical appointment information from the hospital's surgical management system through a preset data interface, and extracts the surgical type (such as cardiac surgery, orthopedic surgery, etc.) and surgical site information (such as chest cavity, abdominal cavity, etc.).

[0023] Step 102: Determine a reference temperature according to the type of surgery.

[0024] Specifically, since different types of surgeries have different temperature requirements, it is necessary to determine the appropriate reference temperature according to the specific type of surgery. The system has pre-established a database of the correspondence between surgery types and reference temperatures, which stores the recommended temperature ranges for various types of surgeries. For example, for cardiac surgery, the corresponding reference temperature is set to 24°C to avoid hypothermia in patients; and for orthopedic surgery, the corresponding reference temperature is set to 22°C to reduce the discomfort of medical staff. The system matches the acquired surgery type information with the database and selects the recommended temperature value for the corresponding type of surgery as the reference temperature.

[0025] Step 103: Determine the reference humidity according to the surgical site information.

[0026] Specifically, since different surgical sites have different sensitivities to environmental humidity, it is necessary to determine the appropriate baseline humidity based on the surgical site information. The system has pre-established a database of correspondence between surgical sites and baseline humidity, which stores the recommended humidity ranges for various surgical sites. For example, for thoracic surgery, in order to prevent excessive drying of organ tissues during surgery, the system sets the baseline humidity to 55%; for abdominal surgery, considering the exposure of the surgical field and the anti-fog requirements of medical equipment, the system sets the baseline humidity to 50%. The system queries the database, matches the extracted surgical site information with the database records, and obtains the corresponding baseline humidity value.

[0027] Step 104: Combine the reference temperature and the reference humidity to obtain initial environmental parameters.

[0028] Specifically, after determining the reference temperature and reference humidity, these two parameters are used as a set of related data to form the initial environmental parameters of the clean room. This method of determining them separately and then combining them not only takes into account the special requirements of the surgical site for humidity, but also realizes the coordinated configuration of temperature and humidity, providing accurate initial parameters for subsequent environmental control.

[0029] Step 20: During the operation, surgical equipment parameters and patient physiological parameters are acquired in real time.

[0030] Specifically, since the working status of medical equipment and the physiological condition of patients will change with the progress of the operation, it is necessary to monitor these changes in real time to determine the stage of the operation. The system establishes a data connection with the medical equipment control system in the clean room to obtain surgical equipment parameters, including the working status of the anesthesia machine (on / off), the number of monitoring equipment turned on, the lighting status of the surgical lamp (standby / full light), the use status of the electric knife, the start and stop status of the aspirator, etc.; at the same time, through the data interface with the patient monitor, the patient's physiological parameters are obtained in real time, including physiological indicators such as heart rate change trend and blood pressure fluctuation. The system uses a preset sampling frequency (for example, sampling once every 30 seconds) to continuously collect these parameters, and classifies and organizes the collected data to form a feature data set reflecting the progress of the operation. This monitoring method based on the combination of equipment working status and changes in patient physiological indicators enables the system to accurately grasp the actual progress of the operation and provide comprehensive data support for the subsequent identification of the surgical stage.

[0031] Step 30: Determine the current surgical stage based on the surgical equipment parameters and the patient's physiological parameters, and determine the target environmental parameters corresponding to the current surgical stage.

[0032] Specifically, due to the different requirements for environmental parameters in different surgical stages, it is necessary to accurately identify the current surgical stage and adjust the environmental parameters accordingly. The system pre-establishes a feature model library for surgical stages, which stores typical feature parameter combinations for each surgical stage. For example, the feature combination of the anesthesia stage is the physiological characteristics of the anesthesia machine turned on, the monitor fully turned on, and the surgical light in standby state, accompanied by a slow decrease in heart rate and a gradual stabilization of blood pressure; the feature combination of the incision stage is the electrosurgical knife turned on, the suction device started, and the surgical light in full light state, accompanied by a slight fluctuation in heart rate and a slight increase in blood pressure; the feature combination of the suturing stage is the main surgical equipment turned off, only basic monitoring equipment is retained, and the patient's physiological indicators tend to be stable. The system performs pattern matching on the real-time collected surgical equipment parameters and patient physiological parameters with the parameter combination in the feature model library to determine the current surgical stage. After determining the surgical stage, the system queries the preset database of surgical stage and environmental parameters to obtain the target temperature and target humidity corresponding to the stage.

[0033] Based on the above embodiment, as an optional embodiment, the step of determining the current surgical stage based on the surgical equipment parameters and the patient's physiological parameters may further include the following steps: Step 201: Generate a physiological characteristic curve according to the patient's physiological parameters.

[0034] Specifically, the collected physiological parameters of the patient are first processed in time series, and the heart rate, blood pressure and other indicators are plotted into continuous physiological characteristic curves according to the sampling time points. This curve can intuitively reflect the dynamic change trend of the patient's physiological state. For example, the anesthesia stage is manifested by a slow decline in the heart rate curve and a stable blood pressure curve; the incision stage is manifested by a small fluctuation in the heart rate curve and a slight increase in the blood pressure curve.

[0035] Step 202: Obtain the start-up timing and operating parameters of each device in the surgical equipment parameters, and construct a device state matrix based on the start-up timing and operating parameters.

[0036] Specifically, the system records the start and stop time points and operating status of each medical device during the operation, and organizes this information into an equipment status matrix. The rows of the matrix represent different medical devices (such as anesthesia machines, monitors, surgical lights, electric knives, aspirators, etc.), the columns represent time series, and the matrix elements record the working status (such as on, standby, off, etc.) and operating parameters of the equipment at the corresponding time points. Through this data structured processing method, the system can clearly grasp the time sequence and combination mode of equipment use. For example, the anesthesia stage is manifested as the anesthesia machine starting first, and the monitoring equipment is turned on later; the incision stage is manifested as the surgical light turning from standby to full light, and the electric knife and aspirator starting one after another. This data processing method based on physiological characteristic curves and equipment status matrices provides a more systematic and reliable basis for subsequent judgments of surgical stages.

[0037] Step 203: Match the physiological characteristic curve with the preset standard curves of each surgical stage to obtain a first matching result.

[0038] Specifically, the generated physiological characteristic curve is pattern matched with the pre-stored standard curves. These standard curves are based on the typical physiological characteristic change patterns of each stage obtained from a large amount of surgical data statistics. For example, the standard curve of the anesthesia stage shows that both heart rate and blood pressure show a steady downward trend, while the standard curve of the incision stage shows characteristic fluctuations in heart rate and blood pressure. The system uses a curve similarity algorithm to calculate the matching degree between the actual curve and the standard curve of each stage, and selects the one with the highest matching degree as the first matching result.

[0039] Step 204: Match the device state matrix with the preset device feature matrix of each surgical stage to obtain a second matching result.

[0040] Specifically, the system pre-stores the equipment feature matrix of each surgical stage, and these feature matrices record the typical equipment combination working modes of different stages. For example, the feature matrix of the anesthesia stage is a feature combination of the anesthesia machine in the "on" state, the monitoring equipment in the "full on" state, and the surgical light in the "standby" state; the feature matrix of the incision stage is a feature combination of the electric knife in the "on" state, the suction device in the "start" state, and the surgical light in the "full light" state. The system uses a matrix similarity calculation method to compare the real-time constructed equipment state matrix with the feature matrix of each stage to calculate the degree of matching between them. In the specific calculation, the device states in the matrix can be numerically processed, such as recording the "on" state as "1", the "standby" state as "0.5", and the "off" state as "0", and then the similarity score is obtained through matrix operation, and the surgical stage corresponding to the feature matrix with the highest similarity is selected as the second matching result.

[0041] Step 205: Determine the current surgical stage according to the first matching result and the second matching result.

[0042] Specifically, the system performs a weighted analysis on the two matching results. When the first matching result and the second matching result point to the same surgical stage, it is directly determined as the current surgical stage. When there is an inconsistency, the system will comprehensively consider the credibility of the two matching results based on the preset weight parameters and select the matching result with higher confidence as the final current surgical stage. This judgment method based on dual verification of physiological characteristics and equipment characteristics significantly improves the accuracy and reliability of surgical stage identification.

[0043] Based on the above embodiment, as an optional embodiment, the step of determining the current surgical stage according to the first matching result and the second matching result may further include the following steps: Step 2051: Determine whether the surgical stage with the highest matching degree in the first matching result and the second matching result is consistent.

[0044] Step 2052: If they are consistent, the surgical stage with the highest matching degree is used as the current surgical stage.

[0045] Specifically, in order to ensure the accuracy of the judgment of the surgical stage, the system needs to conduct a comprehensive analysis of the matching results of the two dimensions of physiological characteristics and equipment characteristics. The surgical stage with the highest matching degree of the physiological characteristic curve and its matching value are obtained from the first matching result, and the surgical stage with the highest matching degree of the equipment state matrix and its matching value are obtained from the second matching result. The system compares the surgical stages corresponding to the two highest matching degrees. When the two point to the same surgical stage, it means that the physiological characteristics and equipment usage characteristics of the current surgery meet the typical characteristics of this stage, and the stage is directly determined as the current surgical stage.

[0046] Step 2053: If there is inconsistency, a surgical process state machine is constructed based on the historical surgical stage data, and the surgical process state machine includes the transition rules and duration constraints of the surgical stages.

[0047] Specifically, when the matching results of physiological characteristics and device characteristics are inconsistent, a surgical process state machine is constructed based on a large amount of historical surgical data. The state machine contains the reasonable conversion relationship between surgical stages and the typical duration of each stage. For example, the state machine stipulates that the surgery must be converted in the order of stage A → stage B → stage C → stage D, and cannot be converted across stages or in reverse order; at the same time, the state machine also records the normal duration range of each stage, such as stage A usually lasts 15-30 minutes, and stage B usually lasts 10-20 minutes.

[0048] Step 2054: Select a surgical stage that meets the state transition rule and duration constraint from the first matching result and the second matching result based on the state machine as the current surgical stage.

[0049] Specifically, the candidate surgical stages and their matching degrees in the first matching result and the second matching result are obtained, and the current state information is obtained from the state machine, including the last confirmed stage and the duration of the stage. The system checks whether each candidate stage satisfies the compliance conversion relationship with the previous stage based on the conversion rules in the state machine. For example, when the last confirmed stage is stage A, only stage B is a compliant next state, and stages C and D do not meet the conversion rules. For candidate stages that meet the conversion rules, the system further checks whether they meet the duration constraint. For example, if the current stage A only lasts for 10 minutes and has not yet reached the minimum duration requirement (15 minutes), even if a candidate stage has a high matching degree, the system will not determine it as the current stage. Among all candidate stages that meet the state conversion rules and duration constraints, the system selects the one with the highest matching degree as the current surgical stage.

[0050] Based on the above embodiment, as an optional embodiment, the step of determining the target environment parameters corresponding to the current surgical stage may further include the following steps: Step 301: Input the operation type and the current operation stage into a preset environmental parameter database to obtain the standard temperature and standard humidity corresponding to the current operation stage.

[0051] Specifically, the system has established an environmental parameter database, which stores the standard temperature and standard humidity values ​​required for different types of surgeries at various stages of surgery. The database uses a two-dimensional index structure, with the type of surgery and the stage of surgery as the query key value. For example, for cardiac surgery, the system sets the standard temperature of its anesthesia stage to 24°C and the standard humidity to 55%, taking into account the characteristics of the patient's weakened body temperature regulation function during anesthesia; and in the incision stage, due to the additional heat generated by the operation of the surgical equipment, the system adjusts the standard temperature to 22°C and maintains the standard humidity at 50%. After determining the current stage of surgery, the system immediately queries the database with the current type of surgery and stage of surgery as the index value to obtain the corresponding standard temperature and standard humidity parameters.

[0052] Step 302: Calculate correction coefficients of standard temperature and standard humidity based on historical surgical data.

[0053] Specifically, the historical surgical data is analyzed to extract the deviation data between the actual operating parameters and the standard parameters of the same type of surgery at the same stage. The temperature correction coefficient and humidity correction coefficient are calculated by statistically analyzing these deviation data. These correction coefficients reflect the empirical correction values ​​in the actual operation of the operating room. For example, the historical data of a certain type of surgery in the incision stage shows that the actual operating temperature is usually 0.5℃ lower than the standard temperature, and the temperature correction coefficient is set to 0.98; while the actual humidity is 2% higher than the standard humidity, and the corresponding humidity correction coefficient is set to 1.04.

[0054] Step 303: Generate target environmental parameters according to the standard temperature, standard humidity and corresponding correction coefficients.

[0055] Specifically, the obtained standard temperature and standard humidity are multiplied by the corresponding correction coefficients to generate the final target temperature and target humidity. For example, when the standard temperature is 22°C and the temperature correction coefficient is 0.98, the final target temperature is set to 21.56°C; when the standard humidity is 50% and the humidity correction coefficient is 1.04, the final target humidity is set to 52%. This parameter correction mechanism based on historical data optimizes the theoretical parameters by introducing actual operating experience, so that the setting of the target environmental parameters is more in line with actual surgical needs, improving the accuracy and adaptability of environmental control.

[0056] Step 40: Adjust the initial environmental parameters based on the target environmental parameters.

[0057] Specifically, in order to ensure the smooth adjustment and precise control of the surgical environment parameters, the system needs to adopt a progressive parameter adjustment strategy. The initial environmental parameters of the operating room can be obtained, and then compared with the calculated target environmental parameters to obtain the temperature difference and humidity difference that need to be adjusted. The system designs the adjustment curve based on these differences and implements parameter adjustment in a segmented and progressive manner. For example, when the initial temperature is 25°C and the target temperature is 21.56°C, the system will decompose the temperature adjustment amount of 3.44°C into multiple small steps, adjust the temperature by 0.5°C each time, and set an appropriate time interval between each adjustment point to ensure the stability of temperature changes; similarly, when the initial humidity is 45% and the target humidity is 52%, the system will divide the 7% humidity adjustment amount into several 1% adjustment steps, which are gradually realized through the coordinated control of the air conditioning and fresh air system. During the parameter adjustment process, the system monitors the changing trend of environmental parameters in real time. When it is detected that the adjustment rate is too fast and may cause environmental fluctuations, it will automatically reduce the adjustment step or extend the adjustment interval to ensure the stable transition of environmental parameters.

[0058] Based on the above embodiment, as an optional embodiment, the step of adjusting the initial environmental parameters based on the target environmental parameters may further include the following steps: Step 401: Calculate the temperature difference and humidity difference between the target environmental parameters and the initial environmental parameters.

[0059] Step 402: Determine the adjustment steps of temperature and humidity according to the temperature difference and humidity difference respectively.

[0060] Specifically, the difference between the target environmental parameters and the initial environmental parameters is calculated, and the difference between the target temperature and the initial temperature is recorded as the temperature difference, and the difference between the target humidity and the initial humidity is recorded as the humidity difference. According to the absolute values ​​of the calculated temperature difference and humidity difference, the corresponding adjustment step is determined in combination with the preset adjustment rules. For example, when the absolute value of the temperature difference is greater than 3°C, the temperature adjustment step is set to 0.5°C. Similarly, when the absolute value of the humidity difference is greater than 5%, the humidity adjustment step is set to 1%. This method of dynamically determining the adjustment step based on the difference ensures both the adjustment efficiency when the difference is large and the adjustment accuracy when it is close to the target value.

[0061] Step 403: Acquire the temperature and humidity response characteristic curve of the clean room, and calculate the adjustment execution timing based on the response characteristic curve.

[0062] Specifically, the temperature and humidity response characteristic curves of the clean room are obtained. These curves reflect the changing rules of the environmental parameters of the clean room under different adjustment instructions. For example, the temperature response characteristic curve shows that it takes about X minutes to reduce the temperature by 1°C, and it presents a nonlinear change characteristic of first fast and then slow; the humidity response characteristic curve shows that it takes about Y minutes to increase the humidity by 1%, and it presents a gradual increase. Based on these response characteristic curves, combined with the aforementioned determined temperature adjustment step (such as 0.5°C) and humidity adjustment step (such as 1%), the optimal adjustment execution sequence is calculated. For example, when the temperature needs to be reduced by 3.44°C, the system decomposes it into 7 adjustment steps of 0.5°C, and sets the time interval between each adjustment step to 2 minutes according to the response characteristic curve to ensure that the next adjustment is made after the previous adjustment is fully effective; similarly, when the humidity needs to be increased by 7%, the system decomposes it into 7 adjustment steps of 1%, and sets the adjustment interval to 1 minute.

[0063] Step 404: Adjust the temperature and humidity parameters step by step according to the adjustment step size and adjustment execution sequence.

[0064] Specifically, the system sends adjustment instructions strictly according to the calculated execution sequence, and monitors the changes in environmental parameters in real time. When the actual response is detected to be different from the expected one, the system will dynamically adjust the subsequent execution sequence to ensure the stability and accuracy of the adjustment process. This precise adjustment mechanism based on response characteristics avoids overshoot and oscillation of parameter adjustment through scientific timing control, and realizes efficient and stable adjustment of environmental parameters.

[0065] Based on the above embodiment, as an optional embodiment, a clean room control method with constant temperature and humidity function may also include the following process: Specifically, in order to promptly detect and handle abnormal fluctuations in environmental parameters, the system sets a multi-level early warning mechanism. The embodiment of the present application sets two warning level thresholds based on surgical safety specifications, where the first warning threshold is relatively conservative, such as the first warning threshold of temperature difference is set to ±2°C, and the first warning threshold of humidity difference is set to ±5%; the second warning threshold corresponds to more serious deviations, the second warning threshold of temperature difference is set to ±4°C, and the second warning threshold of humidity difference is set to ±8%. In the process of performing environmental parameter adjustment, the system calculates and monitors the changes in temperature difference and humidity difference in real time. When it is detected that the temperature difference or humidity difference exceeds the first warning threshold, the system immediately generates a first-level alarm message on the display terminal of the operating room, including the specific parameter deviation value and the time of occurrence, highlighted in yellow font, to remind medical staff in the operating room to pay attention to abnormal environmental parameters. When the temperature difference or humidity difference further deteriorates and exceeds the second warning threshold, in addition to updating the alarm information on the display terminal to red, the system will immediately send an early warning prompt to the operating room manager through a preset communication method (such as text messages, in-hospital communication systems, etc.). The prompt information contains key information such as the operating room number, abnormal parameter type, and specific deviation value, ensuring that the manager can understand the situation in a timely manner and take necessary intervention measures. This hierarchical early warning mechanism achieves timely discovery and rapid response to abnormal environmental parameters through information push at different levels, effectively reducing the risk of out-of-control of surgical environment parameters and providing reliable protection for the safe conduct of surgery.
