Description

Technical Field

[0001] The present invention relates to the field of data processing technology, and in particular to a ventilation control method, device, equipment and storage medium for a pathology laboratory. Background Art

[0002] Cervical cancer is a malignant tumor that develops in the cervix. Its primary cause is persistent infection with high-risk HPV (human papillomavirus). Thinprep cytologic testing (TCT) is a commonly used method for cervical cancer screening. It involves collecting cervical cell samples, fixing, staining, dehydrating, and mounting them to prepare slides for microscopic diagnosis by pathologists. By observing changes in cervical cell morphology, it can help detect precancerous lesions or cancer cells early. In clinical practice, HPV testing (to screen for cancer-causing viruses) and TCT (to observe cell abnormalities) are often combined to more accurately assess cervical cancer risk.

[0003] However, the TCT testing process requires the use of large quantities of volatile organic compounds (VOCs) reagents, such as formaldehyde (a fixative used to fix cell morphology and releases irritating gases); xylene (a dehydrating and clearing agent, volatile and prone to damage the hematopoietic system due to long-term exposure); and resin sealants (containing benzene derivatives, which continuously release carcinogens). VOCs seriously affect the health of medical laboratory technicians.

[0004] Therefore, in pathology laboratories, highly toxic gases are a key area of ​​protection. Current ventilation systems used in TCT testing in pathology laboratories generally use timed-on / off axial flow fans with fixed operating cycles (e.g., 10 minutes every 30 minutes) and no parameter feedback mechanism. This leads to wasted energy during periods of low pollutant concentrations and excessive residual pollutants during peak periods.

[0005] Therefore, there is an urgent need for a pathology laboratory ventilation control method that can solve the technical problem that the existing technology cannot dynamically adjust the laboratory ventilation strategy according to the situation in the pathology laboratory in real time, thereby improving the efficiency of polluted gas treatment and reducing energy consumption. Summary of the Invention

[0018] If the change rate is greater than a preset change rate threshold, the initial weight distribution value corresponding to the volatile organic compound concentration is adjusted according to a weight correction rule.

[0019] Optionally, the step of matching a corresponding ventilation control strategy from a preset multi-stage ventilation response strategy according to the comprehensive pollution index includes:

[0020] Determining the level interval corresponding to the comprehensive pollution index in a preset multi-stage ventilation response strategy;

[0021] The response strategy corresponding to the level interval is used as the ventilation control strategy corresponding to the comprehensive pollution index.

[0022] Optionally, the step of adjusting the operating state of the ventilation system in the pathology laboratory based on the ventilation control strategy includes:

[0023] When the comprehensive pollution index is in the first level interval of the preset multi-level ventilation response strategy, controlling the ventilation device of the ventilation system in the pathology laboratory to operate at a first power;

[0024] When the comprehensive pollution index is in the second level range of the preset multi-level ventilation response strategy, controlling the heating device in the ventilation system to heat up to a target temperature range and maintain a constant temperature state;

[0025] When the comprehensive pollution index is in the third level interval of the preset multi-level ventilation response strategy, the ventilation device is controlled to operate at a third power and an audible and visual alarm is triggered.

[0026] Optionally, the method further includes:

[0027] A slide drying rack is used to process the slides to be processed in the pathology laboratory. The slide drying rack is a stacked hollow rack having honeycomb holes and interlayer flow guide gaps.

[0044] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0045] The embodiment of the present invention provides a pathology laboratory ventilation control method, referring to Figure 1 , Figure 1 Schematic diagram of the first embodiment of the ventilation control method for a pathology laboratory according to the present invention.

[0046] In this embodiment, the pathology laboratory ventilation control method includes steps S10 to S40:

[0047] Step S10: acquiring the pollutant concentration and environmental parameters in the pathology laboratory in real time, wherein the pollutant concentration is the concentration of volatile organic compounds, and the environmental parameters include humidity and temperature.

[0048] It should be noted that the execution subject of this embodiment can be a computer server device with data processing, network communication, and program execution functions used in laboratory ventilation processing scenarios, such as a server, tablet computer, personal computer, etc., or an electronic device capable of performing the above functions (such as a pathology laboratory ventilation control device). The following uses a system including a pathology laboratory ventilation control device (hereinafter referred to as the system) as an example to illustrate this embodiment and the following embodiments.

[0049] It should be understood that in a specific implementation, an electrochemical sensor can be used to obtain the concentration of volatile organic compounds in the pathology laboratory in real time, and a capacitive humidity sensor and a thermistor can be used to obtain the humidity and temperature in the pathology laboratory respectively.

[0050] Step S20: Determine a comprehensive pollution index of the pathology laboratory based on the volatile organic compound concentration, the temperature, and the humidity.

[0051] It should be understood that within a pathology laboratory environment, multiple pollutants and environmental factors collectively impact indoor air quality and worker health. Monitoring a single pollutant concentration or environmental parameter (such as humidity or temperature) alone cannot fully reflect the overall pollution status of a pathology laboratory, and therefore cannot provide a scientific basis for precise ventilation system regulation.

[0052] For example, monitoring only formaldehyde concentrations may overlook the hazards of other volatile organic compounds (VOCs) such as xylene; focusing only on humidity may fail to comprehensively consider the synergistic effects of humidity and pollutant concentrations on gas diffusion and residue. The comprehensive pollution index quantifies the contamination status of pathology laboratories. It is based on multi-parameter monitoring, covering key environmental indicators such as the concentration of volatile organic compounds (VOCs) (such as formaldehyde and xylene), humidity, and temperature.

[0053] In order to ensure the reliability of the comprehensive pollution index, step S20 includes steps S201 to S302:

[0054] Step S201: obtaining initial weight distribution values ​​corresponding to the volatile organic compound concentration, the temperature, and the humidity respectively.

[0055] Step S202: performing normalization processing on the volatile organic compound concentration, the temperature, and the humidity to obtain normalized parameter values, where the normalized parameter values ​​include a normalized concentration value, a normalized temperature value, and a normalized humidity value.

[0056] Step S203: determining the comprehensive contamination index of the pathology laboratory according to the initial weight distribution values ​​and the normalized parameter values.

[0057] It should be noted that the initial weight distribution values ​​can be customized, with the initial weight distribution value for VOC concentration being the largest, the initial weight distribution value for humidity being the second largest, and the initial weight distribution value for temperature being the smallest. For example, the initial weight distribution value for VOC concentration can be 0.6, the initial weight distribution value for humidity can be 0.3, and the initial weight distribution value for temperature can be 0.1.

[0058] It's important to note that because the dimensions and numerical ranges of different parameters vary widely (e.g., formaldehyde concentration is measured in ppm, humidity is expressed as a percentage, and temperature is measured in degrees Celsius), using them directly in calculations can lead to weight bias. Therefore, we first normalize each parameter and map them to a uniform numerical range (e.g., 0-1) to make them comparable.

[0059] In a specific implementation, the comprehensive pollution index of the pathology laboratory can be determined based on the comprehensive pollution index calculation formula according to each of the initial weight distribution values ​​and the normalized parameter value; wherein the comprehensive pollution index calculation formula is as follows:

[0060] PI=Wc×Cnorm+Wh×RHnorm+Wt×Tnorm;

[0061] Where PI represents the comprehensive pollution index, Wc, Wh, and Wt represent the initial weight distribution values ​​of volatile organic compound concentration, humidity, and temperature, respectively, and Cnorm, RHnorm, and Tnorm are the normalized concentration value, normalized humidity value, and normalized temperature value, respectively.

[0062] Step S30: matching a corresponding ventilation control strategy from a preset multi-stage ventilation response strategy according to the comprehensive pollution index.

[0063] It should be noted that the comprehensive pollution index provides the core decision-making basis for the system's intelligent control. Based on the different value ranges of the comprehensive pollution index, pollution levels (such as low, medium, and high pollution) are divided, and corresponding operating modes of the ventilation system are triggered (such as low-power, medium-power, and high-power operation, as well as whether to connect the drying module and sound and light alarms). This enables precise and dynamic ventilation management, effectively reducing pollutant concentrations in the laboratory and ensuring a safe indoor air environment.

[0064] It should be understood that the preset multi-stage ventilation response strategy can be a customized setting based on the current contamination level of the pathology laboratory, and this embodiment is not limited to this.

[0065] For example, a multi-level ventilation response strategy can be: when the comprehensive pollution index is in the low pollution range (i.e., the first level range, such as PI is between 0.1-0.3), the ventilation device of the control system (such as a centrifugal fan) operates at low power (such as 30% power). At this time, the ventilation device can maintain air circulation in the laboratory and meet basic ventilation needs; when the comprehensive pollution index is in the medium pollution range (i.e., the second level range, such as PI is between 0.3-0.6), the operating power of the ventilation equipment is increased to a medium level (such as 60% power) to enhance the ventilation effect and speed up the discharge of pollutants. At the same time, start the drying module (i.e., heating device, such as PTC drying module), set the appropriate temperature (e.g., 40°C), and use hot air to promote the volatilization of organic solvents during the drying process of the glass slides, thereby further reducing the concentration of pollutants. When the comprehensive pollution index is in the high pollution range (i.e., the third level range, such as PI ≥ 0.6), control the ventilation equipment to run at full power (e.g., 100% power) to quickly discharge a large amount of pollutants and reduce the risk of indoor pollution. At the same time, trigger the sound and light alarm device to remind laboratory staff to pay attention to the high pollution state of the current environment and take corresponding protective measures or adjust the experimental operations in a timely manner.

[0066] It should be understood that the multi-level ventilation response strategy offers a degree of flexibility and can be adjusted appropriately based on the laboratory's actual conditions and management requirements. For example, parameters such as the PI threshold, ventilation equipment power, and drying module temperature at each level of response can be optimized and calibrated based on factors such as the laboratory's experimental process, equipment layout, and personnel operating habits to ensure efficient operation of the ventilation system and a safe and reliable laboratory environment.

[0067] In a specific implementation, the level interval corresponding to the comprehensive pollution index in a preset multi-level ventilation response strategy can be determined; and the response strategy corresponding to the level interval is used as the ventilation control strategy corresponding to the comprehensive pollution index.

[0068] Step S40: adjusting the operating state of the ventilation system in the pathology laboratory based on the ventilation control strategy.

[0069] It should be understood that before step S10, it further includes: starting a periodic basis ventilation mode to run the ventilation device of the ventilation system in the pathology laboratory at an initial period and an initial wind speed.

[0070] It should be noted that the existing superimposed slide drying rack in the pathology laboratory has a high concentration of residual xylene at the bottom of 5.2 ppm (10 times the standard). Although stacking 15-20 layers of racks increases the storage capacity, it causes the residual concentration of VOCs at the bottom to reach 5.2 ppm (the TWA limit of xylene is 1.9 ppm), and manual transportation is prone to tipping over (5% of laboratory accident rate).

[0071] Therefore, in order to further improve the effectiveness of the pathology laboratory ventilation control method, the method further includes: using a slide drying rack to process the slides to be processed in the pathology laboratory, the slide drying rack is a superimposed hollow rack, and the hollow rack has honeycomb holes and interlayer flow gap.

[0072] In a specific implementation, a modular hollow rack (such as a single layer of 50 mm high) that can be stacked by 6 layers can be used to eliminate airflow dead angles through honeycomb holes (such as a hole diameter of 3 mm, a hole density of 20 holes / cm 2 ) and interlayer flow gap (such as 15 mm), and to realize airflow penetration drying by connecting an external exhaust ventilation interface.

[0073] It should be noted that the advantages and disadvantages of the rack ventilation performance can also be verified by monitoring the changes of the comprehensive pollution index under different rack structures and stacking methods, and the structure parameters of the honeycomb holes and interlayer flow gap of the hollow rack can be optimized to ensure efficient airflow penetration, reduce VOCs residue at the bottom of the slide, and improve the drying effect and sample quality.

[0074] The embodiment discloses real-time acquisition of a pollutant concentration and an environmental parameter in a pathology laboratory, the pollutant concentration is a volatile organic compound concentration, and the environmental parameter includes humidity and temperature; determination of a comprehensive pollution index of the pathology laboratory based on the volatile organic compound concentration, the temperature, and the humidity; matching of a corresponding ventilation control strategy from a pre-set multi-level ventilation response strategy according to the comprehensive pollution index; and adjustment of an operation state of a ventilation system in the pathology laboratory based on the ventilation control strategy. Since the embodiment determines the comprehensive pollution index of the pathology laboratory according to the pollutant concentration and the environmental parameter in the pathology laboratory, and then adjusts the operation state of the ventilation system in the pathology laboratory based on the comprehensive pollution index and the corresponding ventilation control strategy, compared with the prior art, the embodiment dynamically adjusts the laboratory ventilation strategy according to the situation in the pathology laboratory in real time, improves the volatile organic compound treatment efficiency, and reduces the energy consumption.

[0075] Reference Figure 2 , Figure 22 is a flow chart of the second embodiment of the ventilation control method for a pathology laboratory according to the present invention.

[0076] Based on the first embodiment described above, in this embodiment, before step S203, steps S2031 to S2032 are further included:

[0077] Step S2031: monitoring the change rate of the volatile organic compound concentration, and determining whether the change rate is greater than a preset change rate threshold.

[0078] Step S2032: If the change rate is greater than a preset change rate threshold, the initial weight distribution value corresponding to the volatile organic compound concentration is adjusted according to a weight correction rule.

[0079] It should be understood that the above-mentioned preset change rate threshold may be a user-defined setting, and the following description will be made taking the preset change rate threshold of 20% as an example.

[0080] It should be noted that the weight correction rule may be that when the change rate of the volatile organic compound concentration ΔC ≥ 20%, the initial weight distribution value corresponding to the volatile organic compound concentration is adjusted according to Wc = Wc × (1 + ΔC / 100).

[0081] It should be explained that when the rate of change of volatile organic compound concentration is high (such as ΔC ≥ 20%), it indicates that the system may face a sudden pollution incident or a sharp deterioration in the pollution situation. At this time, by adjusting the weight according to the formula (Wc = Wc × (1 + ΔC / 100)), the weight of volatile organic compound concentration in the comprehensive pollution index calculation is increased. This enables the system to capture changes in pollution risks in a timely and sensitive manner, respond quickly, and adjust the operating status of ventilation equipment in a timely manner to adapt to the current pollution situation.

[0082] In a specific implementation, if the change rate is less than a preset change rate threshold, a step of determining the comprehensive contamination index of the pathology laboratory according to each of the initial weight distribution values ​​and the normalized parameter value is executed.

[0083] The embodiment discloses obtaining initial weight distribution values corresponding to the volatile organic matter concentration, the temperature and the humidity respectively; performing normalization processing on the volatile organic matter concentration, the temperature and the humidity to obtain normalized parameter values, the normalized parameter values including a normalized concentration value, a normalized temperature value and a normalized humidity value; monitoring a change rate of the volatile organic matter concentration and determining whether the change rate is greater than a preset change rate threshold; if the change rate is greater than the preset change rate threshold, adjusting the initial weight distribution value corresponding to the volatile organic matter concentration according to a weight correction rule; and determining a comprehensive pollution index of the pathology laboratory according to the initial weight distribution values and the normalized parameter values. Compared with the prior art, since the embodiment can adjust the weight according to the change rate of the volatile organic matter concentration, the system is more accurate in identifying potential pollution risks, an effective comprehensive pollution index is determined, targeted control measures are taken, and the concentration of pollutants in the pathology laboratory is effectively reduced, thereby ensuring the safety of the indoor air environment.

[0084] Reference Figure 3 , Figure 3 The flowchart of a third embodiment of the pathology laboratory ventilation control method is shown.

[0085] Based on the above embodiments, in the embodiment, the step S40 includes steps S401-S403.

[0086] Step S401: When the comprehensive pollution index is in a first grade interval of the preset multi-grade ventilation response strategy, the ventilation device of the ventilation system in the pathology laboratory is controlled to operate at a first power.

[0087] Step S402: When the comprehensive pollution index is in a second grade interval of the preset multi-grade ventilation response strategy, the heating device in the ventilation system is controlled to heat to a target temperature range and maintain a constant temperature state.

[0088] Step S403: When the comprehensive pollution index is in a third grade interval of the preset multi-grade ventilation response strategy, the ventilation device is controlled to operate at a third power, and an audible and visual alarm is triggered.

[0089] It should be understood that the first grade interval, the second grade interval and the third grade interval correspond to a low pollution interval, a medium pollution interval and a high pollution interval respectively. Therefore, the first power < the second power < the third power.

[0090] This embodiment discloses that when the comprehensive pollution index is within the first level range of the preset multi-level ventilation response strategy, the ventilation device of the ventilation system in the pathology laboratory is controlled to operate at a first power; when the comprehensive pollution index is within the second level range of the preset multi-level ventilation response strategy, the heating device in the ventilation system is controlled to increase the temperature to a target temperature range and maintain a constant temperature; when the comprehensive pollution index is within the third level range of the preset multi-level ventilation response strategy, the ventilation device is controlled to operate at a third power and trigger an audible and visual alarm. Because this embodiment determines the corresponding ventilation control strategy based on the level range of the preset multi-level ventilation response strategy in which the comprehensive pollution index is located to adjust the operating state of the ventilation system in the pathology laboratory, compared to the existing technology, this embodiment further improves the efficiency of polluted gas treatment and reduces energy consumption.

[0091] In addition, an embodiment of the present invention further provides a storage medium on which a pathology laboratory ventilation control program is stored. When the pathology laboratory ventilation control program is executed by a processor, the steps of the pathology laboratory ventilation control method described above are implemented.

[0092] Reference Figure 4 , Figure 4 This is a structural block diagram of the first embodiment of the ventilation control device for a pathology laboratory of the present invention.

[0094] The data detection module 501 is used to obtain the pollutant concentration and environmental parameters in the pathology laboratory in real time. The pollutant concentration is the concentration of volatile organic compounds, and the environmental parameters include humidity and temperature.

[0095] The level determination module 502 is configured to determine a comprehensive pollution index of the pathology laboratory based on the volatile organic compound concentration, the temperature, and the humidity.

[0099] The strategy matching module 503 is further configured to determine a level interval corresponding to the comprehensive pollution index in a preset multi-level ventilation response strategy; and use the response strategy corresponding to the level interval as the ventilation control strategy corresponding to the comprehensive pollution index.

[0100] The data detection module 501 is further configured to start a periodic basic ventilation mode and operate the ventilation device of the ventilation system in the pathology laboratory at an initial period and an initial wind speed.

[0101] This device embodiment discloses real-time acquisition of pollutant concentrations and environmental parameters in a pathology laboratory, wherein the pollutant concentration is a volatile organic compound concentration, and the environmental parameters include humidity and temperature; determining a comprehensive pollution index for the pathology laboratory based on the volatile organic compound concentration, the temperature, and the humidity; matching a corresponding ventilation control strategy from a preset multi-stage ventilation response strategy based on the comprehensive pollution index; and adjusting the operating state of the ventilation system in the pathology laboratory based on the ventilation control strategy. Because this device embodiment determines the comprehensive pollution index of the pathology laboratory based on the pollutant concentrations and environmental parameters in the pathology laboratory, and then matches the corresponding ventilation control strategy based on the comprehensive pollution index to adjust the operating state of the ventilation system in the pathology laboratory, compared to existing technologies, this device embodiment dynamically adjusts the laboratory ventilation strategy in real time based on the situation in the pathology laboratory, thereby improving the efficiency of polluted gas treatment and reducing energy consumption.

[0102] Based on the first embodiment of the ventilation control device for a pathology laboratory of the present invention, a second embodiment of the ventilation control device for a pathology laboratory of the present invention is proposed.
