[0029] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein.

[0030] Example 1

[0031] According to an embodiment of the present invention, a device for detecting pneumoconiosis of an object is provided, which is used to detect pneumoconiosis. Figure 1 is a schematic diagram of a pneumoconiosis detection device according to an embodiment of the present invention. Figure 1 As shown, the pneumoconiosis detection device of the subject comprises: a circulatory breathing sub-device 10 , a detection sub-device 20 and a temperature control sub-device 30 .

[0032] The circulating breathing sub-device 10 at least comprises a breathing mask 101 and a contraction airbag 102, wherein the breathing mask 101 is used to collect the exhaled gas of the subject to be tested, and the contraction airbag 102 is used to obtain and store the exhaled gas through a connecting ring.

[0033] In this embodiment, the subject to be tested wears a breathing mask with a driving seal covering the mouth and nose, then opens the connecting electric control valve on the connecting tube between the breathing mask and the contraction airbag, and closes the blocking electric control valve on the connecting tube. The subject to be tested can breathe normally, and the exhaled gas enters the contraction airbag through the connecting tube. Since the contraction airbag has the characteristics of repeated expansion and contraction, based on this, the exhaled gas in the contraction airbag can enter the breathing mask again through the connecting tube, be inhaled into the respiratory tract by the subject to be tested, and be converted by the lung tissue of the subject to be tested, and then be exhaled through the breathing mask and flow into the contraction airbag. After multiple cycles, the exhaled gas is exhaled into the contraction airbag, the connecting electric control valve on the connecting tube is closed, and the breathing mask worn by the subject to be tested is taken off. Here, the content of the substance to be tested in the exhaled gas stored in the contraction airbag is relatively high. The exhaled gas is used to detect the pneumoconiosis of the subject to be tested, and the accuracy of the test result is higher.

[0034] The detection sub-device 20 at least includes a detection box 201 and an electronic nose detector 202 . The electronic nose detector 202 is disposed in the detection box 201 , and the electronic nose detector 202 is connected to the deflated airbag 102 to obtain and detect the exhaled gas stored in the deflated airbag 102 .

[0035] In this embodiment, the detection box is a sealed physical structure, and the electronic nose detector is an advanced chemical sensor that can simulate the human olfactory system to identify and analyze specific chemical components in the exhaled gas, which may be related to the early signs of pneumoconiosis. By detecting the concentration of these chemical markers, the electronic nose detector can help evaluate whether the subject to be tested suffers from pneumoconiosis, or the degree of progression of the disease. Based on this, the exhaled gas stored in the contraction airbag flows into the electronic nose detector in the detection box through the connecting tube, and the electronic nose detector can detect the substance to be detected in the exhaled gas, and then obtain the test result, which can more accurately indicate whether the subject to be tested suffers from pneumoconiosis and the degree of progression of the disease.

[0036] The temperature control sub-device 30 at least includes a temperature sensor 301, which is connected to the detection box 201 and is used to adjust the temperature inside the detection box to a temperature that matches the electronic nose detector.

[0037] In this embodiment, the main function of the temperature control sub-device is to ensure that the ambient temperature inside the detection box matches the required operating temperature of the electronic nose detector, which is a sensitive chemical sensor that can detect and identify specific chemicals in exhaled gas. However, the performance and accuracy of the electronic nose detector are very sensitive to the temperature of its working environment. Changes in temperature may affect the responsiveness of the sensor, causing drift and instability in the detection data, thereby affecting the accuracy of pneumoconiosis detection. Based on this, the temperature sensor in the temperature control sub-device is connected to the electronic detection nose, which can detect the temperature of the electronic nose detector, and then adjust the temperature of the detection box through a hot air blower and a hot air circulation system (such as an air outlet and a return air duct) to ensure that it is consistent with the optimal operating temperature of the electronic nose detector. This includes raising or lowering the temperature, as well as maintaining a constant temperature environment.

[0038] Next, the pneumoconiosis detection device of the object is further introduced.

[0039] As an optional embodiment, the circulating breathing sub-device 10 also includes: a connecting electric-controlled valve 103 and a blocking electric-controlled valve 104, the connecting electric-controlled valve 103 is arranged on the first connecting pipe between the contraction airbag 102 and the breathing mask 101, and the blocking electric-controlled valve 104 is arranged on the second connecting pipe between the contraction airbag 102 and the electronic nose detector 202, and the connecting electric-controlled valve 103 is used to control the gas flow between the breathing mask 101 and the contraction airbag 102, and the blocking electric-controlled valve 104 is used to control the gas sealing between the contraction airbag 102 and the electronic nose detector 202.

[0040] In this embodiment, if Figure 2 As shown, the connecting electric control valve 103 is installed on the first connecting pipe, between the breathing mask and the contraction airbag. Its main function is to control the circulation of gas at different stages of the detection process. In the cyclic breathing stage, the connecting electric control valve is in an open state, allowing the gas exhaled by the test subject to enter the contraction airbag through the first connecting pipe, and then in the inhalation stage, the gas is released from the contraction airbag again and returns to the respiratory tract of the test subject through the first connecting pipe for recirculation. In this way, through the precise control of the connecting electric control valve, the effective circulation of the exhaled gas between the contraction airbag and the respiratory tract of the test subject is ensured, and the concentration of the substance to be detected is increased.

[0041] Alternatively, if Figure 2As shown, the blocking electric control valve 104 is arranged on the second connecting pipe, between the contraction airbag and the electronic nose detector. Its function is opposite to that of the connecting electric control valve. During the circulation breathing stage, the blocking electric control valve is closed to prevent the gas from flowing directly into the electronic nose detector, thereby ensuring the integrity of the gas circulation. When the gas circulation is completed and the gas stored in the contraction airbag needs to be detected, the blocking electric control valve is opened to allow the gas to enter the electronic nose detector from the contraction airbag through the second connecting pipe for analysis. The control of the blocking electric control valve is crucial to prevent the gas from being detected during the circulation process, and to ensure that the gas only flows to the electronic nose detector during the detection stage to avoid leakage or contamination.

[0042] As an optional implementation, the circulating breathing sub-device 10 also includes: a bracket 105, an intermediate plate 106, a sealing rubber ring 107, a one-way sealing flap 108, an inhalation buffer chamber 109 and an exhalation buffer chamber 110, wherein the bracket is used to fix the breathing mask above the detection box; the intermediate plate is symmetrically fixed in the detection box to support and fix the contraction airbag; the sealing rubber ring is embedded in the inhalation buffer chamber and the exhalation buffer chamber to ensure sealing; the one-way sealing flap is hinged on the outside of the sealing rubber ring to perform one-way circulation conduction of the exhaled gas.

[0043] In this embodiment, the circulating breathing sub-device 10 is a key component in the auxiliary detection device for the electronic nose for detecting pneumoconiosis, and its design purpose is to optimize the collection and circulation process of exhaled gas, increase the concentration of the substance to be detected, and thus enhance the detection effect of the electronic nose detector.

[0044] Alternatively, if Figure 2 As shown, the bracket 105 is used to fix the breathing mask on the top of the detection box to ensure the stability and correct position of the breathing mask during use. The design of the bracket needs to take into account the user's comfort and the close fit of the mask to the face so as to effectively collect the exhaled gas.

[0045] Alternatively, if Figure 2 As shown, the middle plate 106 is symmetrically fixedly arranged in the detection box, and its main function is to support and fix the shrink airbag. The design of the middle plate may include multiple support points or fixed structures to ensure the stability of the shrink airbag during the expansion and contraction process, and avoid gas leakage or cycle failure caused by movement or deformation of the airbag.

[0046] Alternatively, if Figure 2 As shown, the sealing rubber ring 107 is embedded in the connection port of the inhalation buffer chamber 109 and the exhalation buffer chamber 110, and its function is to ensure the sealing of the gas during the circulation process.

[0047] Alternatively, if Figure 2As shown, the one-way sealing flap 108 is hinged on the outside of the sealing rubber ring 107, allowing the exhaled gas to enter the contraction airbag from the exhalation buffer chamber 110 in one direction, but is closed when the contraction airbag transmits gas to the inhalation buffer chamber 109 to prevent gas backflow. This design ensures that the circulation of the exhaled gas between the contraction airbag and the respiratory tract of the subject to be tested is controlled, thereby improving the circulation efficiency and concentration of the substance to be tested in the exhaled gas.

[0048] Optionally, the inhalation buffer chamber 109 and the exhalation buffer chamber 110 are two parts of the circular breathing sub-device, wherein the inhalation buffer chamber 109 is connected to the breathing mask, and the exhalation buffer chamber is connected to the contraction airbag. The exhalation buffer chamber is used to collect and temporarily store the gas exhaled by the subject to be tested, and then transport it to the contraction airbag; the inhalation buffer chamber provides a temporary storage space when the gas returns from the contraction airbag, so that the gas can be inhaled into the respiratory tract of the subject to be tested again through the breathing mask. The design of the buffer chamber can not only adjust the rate of gas flow, but also reduce the impact of airflow on the test results, ensuring a smooth and efficient test process.

[0049] In this device, the circulating breathing sub-device achieves efficient circulation of exhaled gas and increase of the concentration of the substance to be tested through the synergistic effect of its components (breathing mask, contraction airbag, bracket, middle plate, sealing rubber ring, one-way sealing flap, inhalation buffer chamber and exhalation buffer chamber), ensuring the accuracy and reliability of the pneumoconiosis detection process.

[0050] As an optional implementation, both ends of the shrink airbag 102 are installed between the middle plates 106 through threaded sleeves.

[0051] In this embodiment, both ends of the shrink airbag 102 are equipped with threaded interfaces (or threaded sleeves), which match the corresponding threaded holes or threaded components on the middle plate symmetrically fixed inside the detection box. Through the threaded connection, the shrink airbag is safely fixed between the two middle plates. This connection not only provides the necessary mechanical stability, ensures the fixed position of the airbag during expansion and contraction, and avoids gas leakage or other mechanical problems caused by movement or vibration, but also allows the shrink airbag to be easily disassembled and replaced through the design of the threaded sleeve, which is convenient for maintenance and cleaning, or replacement of a new airbag when necessary.

[0052] Optionally, the threaded sleeve is a common fixing method, which can achieve a stable and reliable connection through the engagement of internal and external threads. In the pneumoconiosis detection device, the use of the threaded sleeve ensures the tightness of the connection between the shrink airbag and the middle plate and the convenience of repeated use, and is one of the key technical means to achieve the fixation of the shrink airbag and the stability of its function.

[0053] In this device, threaded sleeves are used at both ends of the shrink airbag to install it between the middle plates in the detection box. This not only provides stable support for the shrink airbag during the detection process, but also facilitates the replacement and maintenance of the airbag. It is an important design detail to ensure the efficient operation of the pneumoconiosis detection device.

[0054] As an optional embodiment, the temperature control sub-device 30 also includes: a hot air blower 302, an air blowing port 303 and a return air duct 304, wherein the hot air blower 302 is installed below the detection box 201, the air blowing port 303 is symmetrically arranged on both sides of the bottom surface of the detection box 201, and the return air duct 304 is symmetrically arranged on both upper side walls of the detection box 201. The hot air blower 302 is used to adjust the temperature inside the detection box 201 to a temperature matching the electronic nose detector 202 through the air blowing port 303 and the return air duct 304.

[0055] In this embodiment, if Figure 2 As shown, the hot air blower 302 is the main heating device in the temperature control sub-device, which is installed below the detection box, near the bottom of the detection box. The function of the hot air blower 302 is to heat the air when necessary, and then send the warm air into the detection box 201 through the air outlet 303 to increase the ambient temperature inside the box. The design of the hot air blower 302 needs to take into account the precise control of temperature and energy efficiency to avoid overheating or temperature fluctuations that affect the performance of the electronic nose detector.

[0056] Optionally, the air outlets 303 are symmetrically arranged on both sides of the bottom surface of the detection box 201, that is, at two relative positions at the bottom of the detection box. The hot air blower 302 is connected to the air outlets 303 through a pipeline, and the heated air is evenly blown into the interior of the detection box 201 to form a hot air circulation system. This design ensures that the temperature inside the detection box can be quickly and evenly increased, avoiding local overheating or uneven temperature.

[0057] Optionally, the return air duct 304 is symmetrically arranged on the upper two side walls of the detection box 201, that is, at two relative positions on the top or side of the detection box. The function of the return air duct 304 is to redirect the air inside the detection box 201 back to the hot air blower 302 to form a closed circulation system. In this way, after the heated air has completed the circulation inside the detection box, it returns to the hot air blower again through the return air duct, which can be further heated or cooled to achieve the goal of matching the working temperature of the electronic nose detector, and can also recycle heat to reduce energy consumption.

[0058] In the device, the temperature control sub-device 30 achieves precise control of the internal temperature of the detection box 201 through the coordinated action of the hot air blower 302, the air outlet 303 and the return air duct 304, ensuring that the electronic nose detector 202 performs the detection of pneumoconiosis-related exhaled gas under optimal temperature conditions, thereby improving the accuracy and reliability of the detection results.

[0059] As an optional implementation, the temperature control sub-device 13 further includes a heat preservation layer 305 , which is disposed on the inner wall of the detection box 201 to increase the heat preservation effect of the detection box 201 .

[0060] In this embodiment, if Figure 2 As shown, the insulation layer 305 is located on the inner wall of the detection box 201, that is, the insulation layer 305 is directly wrapped around the inner space of the detection box 201 to form a heat insulation barrier. The insulation layer 305 can be made of a variety of materials, such as foam plastics, glass wool, rock wool or polyurethane foam, etc. These materials have good heat insulation properties and can effectively reduce heat loss.

[0061] As an optional implementation, the detection sub-device 20 further includes: a display control panel 203, which is arranged on one side of the detection box 201 and is used to display detection data.

[0062] In this embodiment, if Figure 2 As shown, the display control panel 203 is arranged on one side of the detection box 201, usually in a position convenient for the operator to observe and operate. The display control panel 203 may adopt a touch screen or a physical button combined with a display screen design to provide a user-friendly interactive interface. This layout not only facilitates the user to view data in real time during the detection process, but also makes the operation of the entire device more intuitive and convenient.

[0063] As an optional implementation, the output end of the electronic nose detector 202 is connected to the outside of the detection box 201 through the air outlet pipe 204 to discharge the exhaled gas after detection.

[0064] In this embodiment, as shown in Figure 2, the output end of the electronic nose detector 202 is connected to the outside of the detection box 201 through an outlet pipe 204. The outlet pipe is a specially designed pipeline used to guide the detected gas from the inside of the electronic nose detector to the outside of the detection box to achieve gas discharge.

[0065] As an optional implementation, Figure 3 As shown, the detection sub-device 20 can also include an exhaust pipe 205, an exhaust pump 206, an exhaust pipe 207, and a first blocking electrically controlled valve 208 is arranged on the exhaust pipe 205, wherein the first blocking electrically controlled valve 208 is used to control the conduction and closing of the exhaust and detection pipelines, and an exhaust pump 206 is arranged on the exhaust pipe 205, and an exhaust pipe 207 is arranged at the output end of the exhaust pump 206, and the exhaust pipe 207 is connected to the outside of the detection box 201. After the detection is completed, the shrink airbag 102 is evacuated to avoid affecting the detection result of the next patient to be detected.

[0066] As an optional implementation, the pneumoconiosis detection device of the object further includes a disinfection sub-device 40, and the disinfection sub-device 40 is used to disinfect the breathing mask.

[0067] In this embodiment, if Figure 4 As shown, the disinfection sub-device 40 can be placed on one side above the detection box, and the respiratory mask can be placed in the disinfection sub-device 40. The disinfection sub-device 40 can disinfect the respiratory mask to avoid cross infection when different people use the respiratory mask. Among them, the disinfection sub-device 40 can disinfect the respiratory mask by ultraviolet rays.

[0068] According to an embodiment of the present invention, a system for detecting pneumoconiosis of an object is provided. Figure 5 is a schematic diagram of a pneumoconiosis detection system of an object in an embodiment of the present invention, such as Figure 5 As shown, the pneumoconiosis detection system of the subject includes: an identification detection module 501 and a data correction module 502.

[0069] The identification detection module 501 is used to detect the exhaled gas of the object to be detected and obtain an initial detection result, wherein the initial detection result is used to characterize the estimated content of the substance to be detected in the exhaled gas; the data correction module 502 is used to correct the initial detection result according to polynomial fitting and regularization processing to obtain a target detection result, wherein the target detection result is used to characterize the actual content of the substance to be detected in the exhaled gas.

[0070] In this embodiment, the identification and detection module analyzes and detects the exhaled gas of the subject based on the output of the electronic nose detector. The electronic nose detector is usually composed of a group of sensors that can detect the concentration of specific chemical markers or volatile organic compounds in the gas, and these markers may be related to the early onset of pneumoconiosis.

[0071] Optionally, after analyzing the exhaled gas, the identification and detection module generates an initial detection result, which reflects the estimated content of the substance to be detected in the exhaled gas measured by the electronic nose detector. Due to the performance of the sensor, environmental factors, and variability in the gas collection and processing process, this estimated content may not be completely accurate, so a subsequent data correction process is required.

[0072] Optionally, the data correction module is a processing step after the identification detection module, and its main goal is to improve the accuracy of the initial detection result and obtain a target detection result that is closer to the actual content. The data correction module corrects the detection data through mathematical analysis and algorithm processing.

[0073] Optionally, the data correction module can use polynomial fitting technology to fit the relationship between the sensor output and the concentration of the substance to be detected. Polynomial fitting is a statistical method that describes the nonlinear relationship between variables by fitting a polynomial curve. In pneumoconiosis detection, polynomial fitting can be used to compensate for possible nonlinear drift in the sensor response, which may be caused by temperature, humidity or other environmental factors.

[0074] Optionally, in order to prevent overfitting during the polynomial fitting process, that is, fitting an overly complex model, the data correction module will also apply regularization. Regularization is a technique in statistics and machine learning that limits the complexity of the model by introducing a penalty term in the polynomial model, thereby improving the generalization ability of the model. In this system, regularization can ensure that the fitted polynomial model can not only fit the existing data well, but also is not too complex, so that the model can maintain a high detection accuracy on new data points.

[0075] Optionally, after polynomial fitting and regularization processing, the data correction module will output a target detection result, which more accurately reflects the actual content of the substance to be detected in the exhaled gas. The target detection result is the detection data that the pneumoconiosis detection system ultimately provides to doctors or users, and is used to judge the health status or disease progression of the subject to be detected.

[0076] In the pneumoconiosis detection system of the object, through the collaborative work of the identification detection module and the data correction module, the pneumoconiosis detection system can provide a more accurate evaluation of the content of the substance to be detected in the exhaled gas, thereby facilitating the early diagnosis and treatment of pneumoconiosis.

[0077] The technical solution of the embodiment of the present invention is illustrated below in conjunction with preferred implementation modes.

[0078] Currently, the diagnosis of pneumoconiosis mainly relies on chest X-rays or lung CT scans, which can identify the progression and extent of pulmonary fibrosis. However, pneumoconiosis has a delayed onset and a long incubation period, and early lesions may not be easily visible on images, making early diagnosis difficult. In addition, imaging examinations have high requirements for equipment and operators, are relatively expensive, and are limited in their application in certain working environments.

[0079] Among the related technologies, electronic nose detection technology, as an emerging non-invasive detection method, has received widespread attention in the medical field in recent years. The electronic nose simulates the human olfactory system and uses a series of sensors to detect and analyze chemical markers in exhaled gas, which may be associated with specific disease states. For the detection of pneumoconiosis, the electronic nose can identify the concentration of specific volatile organic compounds related to pulmonary fibrosis in the exhaled gas, providing a potential early diagnosis method. However, only 20%-30% of the gas in the exhaled gas detected by the electronic nose is absorbed and converted by the alveoli to become gas containing the required detection substance, which causes the concentration of the detection substance to be significantly diluted. The existing treatment method is to adsorb some useless substances through physical adsorption materials, but this adsorption treatment method cannot ensure that only the substances to be detected are filtered out, and filtering out high-concentration detection substances is very difficult to achieve. At the same time, since the exhaled gas of the human body has a certain temperature during detection, direct detection will cause the sensor detection accuracy to fluctuate due to temperature changes, and accurate detection data cannot be obtained, which in turn affects the sensitivity and accuracy of the detection. Secondly, due to changes in the temperature and humidity of exhaled breath, the response of the electronic nose sensor may fluctuate, affecting the consistency and reliability of the detection results.

[0080] However, the embodiment of the present invention proposes a pneumoconiosis detection device, which uses a circulating breathing mechanism, a specific air bag and a pipe system to enable the gas exhaled by the person to be tested to circulate in a closed space and pass through the alveoli many times, thereby significantly increasing the concentration of the substance to be detected in the exhaled gas (such as volatile organic compounds related to pneumoconiosis), overcoming the problem of low concentration of substances in the direct detection of exhaled gas, and considering that the temperature and humidity of the exhaled gas may affect the accuracy of the electronic nose sensor, a temperature sensor and a hot air blower are introduced to form a temperature control mechanism to adjust the environment in the detection box to match the temperature and humidity of the exhaled gas, thereby reducing the detection error caused by temperature changes. In addition, a data correction module is also proposed, which corrects the detection data of the electronic nose sensor through polynomial fitting and regularization processing, compensates for the drift caused by environmental factors, and improves the accuracy and reliability of the detection results.

[0081] Next, the pneumoconiosis detection method in the embodiment of the present invention is further introduced.

[0082] Figure 6 is a flow chart of a method for detecting pneumoconiosis of an object according to an embodiment of the present invention. Figure 6 As shown, the pneumoconiosis detection method of the subject comprises the following steps:

[0083] Step S601, obtaining the exhaled gas of the subject to be tested.

[0084] In this embodiment, the person to be tested wears the breathing mask in a sealed form covering the mouth and nose to ensure that the collected exhaled gas is not diluted by the outside air. The equipment is started, the connecting electric control valve is opened, and the blocking electric control valve is closed, allowing the exhaled gas to circulate repeatedly between the contraction airbag and the respiratory tract of the person to be tested. This process can enhance the concentration of the substance to be detected in the gas, because each cycle allows part of the gas to pass through the alveoli, which may further absorb and convert more related compounds. After multiple cycles, the person to be tested completely transfers the exhaled gas to the contraction airbag (by closing the connecting electric control valve), then takes off the mask and prepares for gas detection.

[0085] Step S602, detecting the exhaled gas to obtain an initial detection result.

[0086] In this embodiment, the blocking electric control valve is opened, the air pump is started, and the exhaled gas in the contracted air bag is extracted through the air suction tube and input into the electronic nose detector. The electronic nose detector analyzes specific chemical markers in the gas through its built-in sensors to capture data on potential markers of pneumoconiosis.

[0087] Step S603, compensating and correcting the initial detection result to obtain the target detection result.

[0088] In this embodiment, during the detection process, the data correction module will correct and judge the detection data through polynomial fitting and regularization processing according to the temperature and humidity environment of the sensor. This step can compensate for the sensor response fluctuation caused by environmental changes and improve the accuracy of the data.

[0089] Optionally, the corrected data is deeply analyzed by the recognition and detection module to finally obtain the target detection result, that is, the actual content of pneumoconiosis-related substances in the exhaled gas. This result is displayed on the display control panel for interpretation by the operator or doctor.

[0090] Optionally, after the test is finished, the exhaled gas after the test can be discharged from the test box through the air outlet pipe to avoid contamination to the next test.

[0091] In the above steps S601 to S603, the acquired exhaled gas has been repeatedly circulated between the contraction airbag and the respiratory tract of the subject to be tested, which significantly increases the concentration of the substance to be tested in the exhaled gas, thereby improving the detection accuracy of pneumoconiosis in the subsequent detection process. At the same time, the correction compensation method of polynomial fitting and regularization processing is used to effectively reduce the influence of temperature during the detection process, making the detection more accurate and reliable.
