Description

Technical Field

[0001] This invention relates to the field of disease diagnosis technology, specifically to a disease diagnostic instrument based on respiratory gas analysis. Background Technology

[0002] In the medical field, accurate diagnosis of diseases is crucial for effective treatment and rehabilitation of patients. Traditional diagnostic methods are diverse, including blood tests and imaging examinations, but these methods often have certain limitations. For example, blood tests require the collection of the patient's blood, causing some discomfort, and the testing process is relatively complex and time-consuming. Imaging examination equipment is expensive and has limited sensitivity in detecting some early-stage diseases. With the continuous deepening of medical research, respiratory gas analysis has gradually gained attention as an emerging diagnostic technology. Human respiratory gases contain a variety of biomarkers related to health status. By analyzing these biomarkers, information about the physiological and pathological state of the human body can be obtained. For example, changes in the content of certain volatile organic compounds (VOCs) may be closely related to specific diseases such as cancer, lung diseases, and diabetes. Respiratory gas analysis has the advantages of being non-invasive, convenient, and rapid, and can detect potential signs of diseases at an early stage, providing strong support for the early diagnosis and treatment of diseases.

[0003] However, current disease diagnostic technologies based on respiratory gas analysis still have many problems. On the one hand, existing respiratory gas collection and detection equipment is inefficient. Many devices require patients to cooperate for a long time, and each test can only analyze a small amount of gas sample, resulting in a slow testing process that cannot meet the needs of rapid clinical diagnosis. For example, some traditional diagnostic instruments lack effective temporary storage and rapid analysis mechanisms when collecting respiratory gases, making the entire diagnostic process cumbersome and wasting a lot of time and medical resources. On the other hand, the hygiene and safety of the equipment cannot be ignored. During repeated use, gas collection and temporary storage components are easily contaminated. If they are not cleaned and disinfected in a timely and effective manner, cross-infection is very likely to occur, which will seriously affect the accuracy of the test results. For example, after multiple uses, residual gas and impurities in components such as gas storage tanks may interfere with subsequent tests, leading to misdiagnosis or missed diagnosis. Summary of the Invention

[0004] The purpose of this invention is to provide a disease diagnostic instrument based on respiratory gas analysis, so as to solve the problems of low working efficiency and easy cross-infection of existing respiratory gas analysis diagnostic equipment mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a disease diagnostic instrument based on respiratory gas analysis, comprising a functional box, wherein a first air inlet connector is fixedly disposed on the outer surface of one side of the lower end of the functional box, and one end of the first air inlet connector is fixedly connected to one end of a first air inlet hose, and the other end of the first air inlet hose is fixedly connected to an air blowing tube; a display screen is fixedly mounted on the upper surface of the functional box; and a dynamic detection mechanism is disposed inside the functional box to accelerate the overall working efficiency of the diagnostic instrument by collecting and temporarily storing respiratory gases.

[0006] The dynamic detection mechanism includes: a central motor, which is fixedly installed inside the lower surface of the functional box, and the upper end of the output shaft of the central motor penetrates the inner bottom surface of the functional box. A central seat is fixedly connected to the upper end of the output shaft of the central motor. A gas storage groove is opened on the upper surface of the central seat. A sealing plate is fixedly installed on the inner top surface of the functional box. A gas detection module is fixedly installed inside the lower surface of the sealing plate. A partition plate is fixedly installed on the upper surface of the sealing plate. A sealing cylinder is fixedly installed inside the functional box. A first clearance groove is opened on the outer surface of the central seat. A second clearance groove is opened on the outer surface of the sealing cylinder. A third clearance groove is opened on the outer surface of the sealing plate. A second air inlet connector is fixedly installed on the outer surface of the sealing cylinder. A second air inlet hose is fixedly connected between the second air inlet connector and the first air inlet connector.

[0007] The surface of the functional box is equipped with a self-cleaning mechanism, which cleans and disinfects the inner surface of the gas storage tank to prevent cross-infection from affecting the accuracy of the test results during use.

[0008] The self-cleaning mechanism includes: a first switching motor and a second switching motor. The first and second switching motors are fixedly installed on the inner top surface of the functional box. One end of the output shaft of the first switching motor is fixedly connected to a cleaning tube, and one end of the output shaft of the second switching motor is fixedly connected to an ultraviolet lamp. One end of a power supply line is fixedly connected to the upper end of the ultraviolet lamp, and the other end of the power supply line is connected to a power supply. One end of a fluid input pipe is fixedly connected to the upper end of the cleaning tube, and the other end of the fluid input pipe is fixedly connected to a solenoid valve. An external connector is fixedly installed on the upper outer surface of the functional box, and a connecting groove is opened inside the functional box surface between the external connector and the solenoid valve. A guide groove is opened inside the side surface of the functional box, and a discharge connector is fixedly installed on the outer surface of the functional box opposite to the guide groove.

[0009] An exhaust hole is provided on the outer surface of one end of the sealing plate, and an installation box is fixedly installed on the upper surface of the sealing plate above the exhaust hole. An exhaust pipe is fixedly installed on the outer surface of the installation box. A rotating impeller is installed inside the installation box, and one end of the impeller shaft passes through the outer surface of the installation box. A baffle plate is fixedly connected to the end of the impeller shaft outside the installation box. A baffle sensor is fixedly installed on the outer surface of the installation box.

[0010] Preferably, the outer surface of the center seat is in contact with the inner surface of the sealed cylinder, the air storage grooves are evenly distributed on the upper surface of the center seat, the lower surface of the sealing plate is in contact with the upper surface of the center seat, the outer surface of the sealing plate is in contact with the inner surface of the sealed cylinder, and the upper end of the sealed cylinder is in contact with the inner bottom surface of the functional box.

[0011] By adopting the above technical solution, the entire dynamic detection mechanism can form a relatively closed and stable spatial structure. This close fit design can effectively prevent the leakage of breathing gas, ensure that the collected gas can be accurately detected, avoid gas leakage affecting the accuracy of the detection results, and at the same time ensure the stability of the central seat during rotation, so that it can smoothly drive the gas storage tank to collect and temporarily store gas.

[0012] Preferably, the partition plates are evenly distributed on the upper surface of the closed plate, and the partition plates and the third clearance grooves are arranged in a one-to-one correspondence. The partition plates are located between the two third clearance grooves, the upper end of the air storage groove is located between the two partition plates, one end of the second air inlet connector penetrates the inner surface of the closed cylinder, and the second air inlet connector is set directly opposite the first clearance groove.

[0013] By adopting the above technical solution, the separator can isolate the gases in different gas storage tanks, avoiding the mixing of gases collected from different batches and interference with the detection results. The direct alignment of the second air inlet connector and the first clearance slot, as well as the cooperation of related structures, allows breathing gas to smoothly enter the gas storage tank from the second air inlet connector through the first clearance slot, ensuring a smooth gas collection path and improving the efficiency and accuracy of gas collection by the equipment.

[0014] Preferably, the cleaning tube is cylindrical in shape, and the outer surface of the cleaning tube is uniformly provided with holes, and the cleaning tube is positioned directly opposite the second clearance groove.

[0015] By adopting the above technical solution, the cleaning pipe with a columnar design and evenly spaced holes on the outside can evenly spray the incoming cleaning liquid or drying gas onto the inner surface of the gas storage tank when facing the second clearance tank. This ensures that the cleaning and drying work is carried out thoroughly and evenly, effectively removing residual gas and impurities in the gas storage tank, avoiding cross-contamination due to incomplete cleaning, ensuring the hygiene of the equipment, and thus guaranteeing the accuracy of the test results.

[0016] Preferably, the ultraviolet lamp is positioned directly opposite the second clearance groove, and the outer diameter of the ultraviolet lamp and the cleaning tube is smaller than the width of the second clearance groove.

[0017] Using the above technical solution, the ultraviolet lamp tube is directly facing the second clearance groove, which can directly disinfect the gas storage tank when it is rotated to the corresponding position, ensuring the disinfection effect. The outer diameter of the ultraviolet lamp tube and the cleaning tube is smaller than the width of the second clearance groove, which makes it easier for them to enter the area where the gas storage tank is located through the second clearance groove for cleaning and disinfection.

[0018] Preferably, the second clearance groove is positioned directly opposite the guide groove, and the end of the guide groove facing the closed cylinder is in contact with the outer surface of the closed cylinder.

[0019] By adopting the above technical solution, the waste liquid or waste gas generated from cleaning and disinfecting the gas storage tank can smoothly enter the guide tank through the second clearance tank and then be discharged from the equipment through the discharge connector. This design ensures the cleanliness of the equipment interior, avoids waste liquid and waste gas residue from interfering with subsequent testing, maintains the normal operating environment of the equipment, and ensures the smooth progress of testing work.

[0020] Preferably, the upper end of the exhaust port is fixedly connected to the lower end of the exhaust pipe, and the upper end of the exhaust pipe penetrates the upper surface of the functional box.

[0021] The above technical solution provides a smooth outlet for the excess gas exhaled by the patient, ensuring stable gas pressure inside the functional box and preventing gas accumulation from affecting the detection process. At the same time, it ensures smooth gas flow inside the device, which is conducive to the normal collection and detection of respiratory gases and avoids detection errors caused by gas blockage.

[0022] Preferably, the outer surface of the impeller is in contact with the inner surface of the mounting box, and one end of the shading sensor is positioned directly opposite the shading plate.

[0023] Using the above technical solution, the impeller and the mounting box fit tightly together to ensure stable rotation under the propulsion of gas. By using the baffle plate to block the sensor frequency as the impeller rotates, the amount of gas exhaled by the patient can be accurately monitored. This design provides an accurate basis for the control center to start the motor to switch the gas storage tank, ensuring that the gas storage tank can collect enough exhaled gas from the patient, thereby ensuring the accuracy of the test results.

[0024] Compared with the prior art, the beneficial effects of the present invention are: This disease diagnostic instrument based on respiratory gas analysis:

[0025] 1. The central motor drives the central seat to rotate. The evenly distributed gas storage tanks on the central seat can collect and temporarily store respiratory gases in sequence. During the rotation of the central seat, the gas in different gas storage tanks can be continuously delivered to the gas detection module for detection. This avoids the drawback of traditional equipment that can only detect a small amount of gas sample at a time, realizes continuous detection of respiratory gases, greatly speeds up the overall working efficiency of the diagnostic instrument, meets the needs of rapid clinical diagnosis, and reduces patient waiting time and waste of medical resources.

[0026] 2. The self-cleaning mechanism effectively avoids the impact of cross-infection on test results. The first and second switching motors can control the cleaning tube and the ultraviolet lamp to flip downwards and operate, respectively. Holes are evenly opened on the outer surface of the cleaning tube. The two can evenly spray the cleaning liquid and drying gas introduced by the fluid input tube onto the inner surface of the gas storage tank for cleaning and drying. The ultraviolet lamp can disinfect the gas storage tank after cleaning, ensuring that the gas storage tank is always in a clean and sterile state, preventing residual gas and impurities from interfering with subsequent tests, thereby ensuring the accuracy of test results and reducing the probability of misdiagnosis and missed diagnosis.

[0027] 3. When the impeller is driven to rotate by the patient's exhaled gas, the obstruction frequency of the obstruction sensor by the baffle plate monitors the amount of gas exhaled by the patient. When the amount of gas exhaled by the patient reaches the standard, the controller built into the display screen controls the central motor to start switching the gas storage tank to ensure that the gas storage tank is filled with the patient's exhaled gas to ensure the accuracy of the detection.

[0040] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0041] Please see Figures 1-11 The present invention provides a technical solution: a disease diagnostic instrument based on respiratory gas analysis.

[0042] Example 1: This example discloses a function box 1. A first air inlet connector 2 is fixedly provided on the outer surface of one side of the lower end of the function box 1. One end of the first air inlet connector 2 is fixedly connected to one end of the first air inlet hose 3, and the other end of the first air inlet hose 3 is fixedly connected to an air blower 4. A display screen 5 is fixedly installed on the upper surface of the function box 1. A dynamic detection mechanism is provided inside the function box 1 to accelerate the overall working efficiency of the diagnostic instrument by collecting and temporarily storing the breathing gas.

[0043] The dynamic detection mechanism includes: a central motor 6, which is fixedly installed inside the lower surface of the functional box 1, and the upper end of the output shaft of the central motor 6 penetrates the inner bottom surface of the functional box 1. A central seat 7 is fixedly connected to the upper end of the output shaft of the central motor 6. An air storage groove 8 is opened on the upper surface of the central seat 7. A sealing plate 9 is fixedly installed on the inner top surface of the functional box 1. A gas detection module 10 is fixedly installed inside the lower surface of the sealing plate 9. A partition plate 11 is fixedly installed on the upper surface of the sealing plate 9. A sealing cylinder 12 is fixedly installed inside the functional box 1. A first clearance groove 13 is opened on the outer surface of the central seat 7. A second clearance groove 14 is opened on the outer surface of the sealing cylinder 12. A third clearance groove 15 is opened on the outer surface of the sealing plate 9. A second air inlet connector 16 is fixedly installed on the outer surface of the sealing cylinder 12. A second air inlet hose 17 is fixedly connected between the second air inlet connector 16 and the first air inlet connector 2.

[0044] The outer surface of the center seat 7 is in contact with the inner surface of the closed cylinder 12. The air storage grooves 8 are evenly distributed on the upper surface of the center seat 7. The lower surface of the sealing plate 9 is in contact with the upper surface of the center seat 7, and the outer surface of the sealing plate 9 is in contact with the inner surface of the closed cylinder 12. The upper end of the closed cylinder 12 is in contact with the inner bottom surface of the functional box 1.

[0045] The partition plates 11 are evenly distributed on the upper surface of the closed plate 9, and the partition plates 11 and the third clearance grooves 15 are arranged in a one-to-one correspondence. The partition plates 11 are located between the two third clearance grooves 15. The upper end of the gas storage tank 8 is located between the two partition plates 11. One end of the second air inlet connector 16 penetrates the inner surface of the closed cylinder 12, and the second air inlet connector 16 is set directly opposite the first clearance groove 13.

[0046] When the patient uses the device, they exhale through the mouthpiece of the air inhaler 4. The exhaled air passes through the first air inlet hose 3 and the first air inlet connector 2, then through the second air inlet hose 17 and the second air inlet connector 16, and enters the functional box 1. The air then enters the central storage tank 8 through the second clearance groove 14 on the side surface of the sealed cylinder 12 and the first clearance groove 13 on the side surface of the central seat 7. The central motor 6 starts, driving the central seat 7 to rotate. Since the storage tanks 8 are evenly distributed on the central seat 7, as the central seat 7 rotates, the different storage tanks 8 rotate sequentially to the gas detection module 10 below the lower surface of the sealed plate 9. When the storage tank 8 corresponds to the position of the gas detection module 10, the gas in the tank is detected and analyzed, and the results are displayed on the display screen 5. Because the central seat 7 rotates periodically, the position of the storage tanks 8 is constantly changed, realizing the periodic collection, temporary storage, and detection of respiratory gas. Compared with traditional equipment that detects a small number of gas samples at a time, this greatly improves the overall working efficiency of the diagnostic instrument.

[0047] Example 2: Based on Example 1, this example discloses that the surface of the functional box 1 is provided with a self-cleaning mechanism, which avoids cross-infection of the gas storage tank 8 during use by cleaning and disinfecting the inner surface of the gas storage tank 8;

[0048] The self-cleaning mechanism includes: a first switching motor 18 and a second switching motor 20. The first switching motor 18 and the second switching motor 20 are fixedly installed on the inner top surface of the functional box 1. One end of the output shaft of the first switching motor 18 is fixedly connected to a cleaning tube 19. One end of the output shaft of the second switching motor 20 is fixedly connected to an ultraviolet lamp tube 21. One end of a power supply line 22 is fixedly connected to the upper end of the ultraviolet lamp tube 21, and the other end of the power supply line 22 is connected to a power supply. One end of a fluid input tube 23 is fixedly connected to the upper end of the cleaning tube 19, and the other end of the fluid input tube 23 is fixedly connected to a solenoid valve 24. An external connector 25 is fixedly installed on the outer surface of the upper end of the functional box 1. A connecting groove 26 is opened inside the surface of the functional box 1 between the external connector 25 and the solenoid valve 24. A guide groove 27 is opened inside the side surface of the functional box 1, and a discharge connector 28 is fixedly installed on the outer surface of the functional box 1 opposite to the guide groove 27.

[0049] The cleaning tube 19 is cylindrical in shape, and the outer surface of the cleaning tube 19 is evenly provided with holes, and the cleaning tube 19 is positioned directly opposite the second clearance groove 14.

[0050] The ultraviolet lamp tube 21 is positioned directly opposite the second clearance groove 14, and the outer diameter of the ultraviolet lamp tube 21 and the cleaning tube 19 is smaller than the groove width of the second clearance groove 14.

[0051] The second clearance groove 14 is positioned directly opposite the guide groove 27, and the end of the guide groove 27 facing the closed cylinder 12 is in contact with the outer surface of the closed cylinder 12.

[0052] When the gas storage tank 8 needs to be cleaned and disinfected, the first switching motor 18 starts, and its output shaft drives the cleaning tube 19 to flip downwards and pass through the third clearance groove 15. The external connector 25 connects to the external cleaning liquid source, and the solenoid valve 24 is opened. The cleaning liquid enters the cleaning tube 19 through the connecting groove 26 and the fluid input pipe 23. The cleaning tube 19 is columnar and has holes evenly opened on the outside and is directly facing the second clearance groove 14. It can evenly spray the cleaning liquid onto the inner surface of the gas storage tank 8 to complete the cleaning. The first switching motor 18 starts and drives the cleaning tube 19 to flip upwards and reset.

[0053] After cleaning, the gas storage tank 8 rotates to the bottom of another cleaning pipe 19 when the center seat 7 is rotated. At this time, the cleaning pipe 19 is rotated downward and connected to an external drying gas source through the external connector 25 to inject drying gas for drying.

[0054] After drying, the dried gas storage tank 8 rotates to the position below the ultraviolet lamp 21 when the central seat 7 is rotated. The second switching motor 20 starts, causing the ultraviolet lamp 21 to flip downwards. The ultraviolet lamp 21 is connected to the power supply line 22 to start disinfecting the gas storage tank 8. The waste liquid or waste gas generated during cleaning and disinfection is discharged from the discharge connector 28 through the guide channel 27, thereby ensuring that the gas storage tank 8 is in a clean and sterile state, avoiding cross-infection, and ensuring the accuracy of the test results. The partition plate 11 provides relative isolation between different gas storage tanks 8 to avoid cross-infection between clean and uncleaned gas storage tanks 8.

[0055] Example 3: Based on Examples 1 and 2, this example discloses that an exhaust hole 29 is provided on the outer surface of one end of the sealing plate 9, and an installation box 30 is fixedly provided on the upper surface of the sealing plate 9 above the exhaust hole 29. An exhaust pipe 31 is fixedly provided on the outer surface of the installation box 30. A rotating impeller 32 is installed inside the installation box 30, and one end of the shaft of the impeller 32 passes through the outer surface of the installation box 30. A baffle plate 33 is fixedly connected to the end of the shaft of the impeller 32 located outside the installation box 30. A baffle sensor 34 is fixedly installed on the outer surface of the installation box 30.

[0056] The upper end of the exhaust port 29 is fixedly connected to the lower end of the exhaust pipe 31, and the upper end of the exhaust pipe 31 penetrates the upper surface of the functional box 1.

[0057] The outer surface of the impeller 32 is in contact with the inner surface of the mounting box 30, and one end of the blocking sensor 34 is positioned directly opposite the blocking plate 33.

[0058] When the patient exhales, the exhaled air enters the mounting box 30 through the exhaust port 29 and exits upward through the exhaust pipe 31 to the functional box 1, driving the impeller 32 to rotate. The baffle plate 33 connected to one end of the impeller 32 shaft rotates accordingly. When the baffle plate 33 rotates and blocks the blocking sensor 34 on the outside of the mounting box 30, the blocking sensor 34 will generate a signal change. By measuring the blocking frequency of the blocking sensor 34 by the baffle plate 33, the amount of exhaled air by the patient can be monitored. When the amount of exhaled air reaches the preset standard, the controller built into the display screen 5 controls the central motor 6 to start and switch the air storage tank 8. This ensures that the air storage tank 8 is full of the patient's exhaled air, providing sufficient samples for subsequent accurate testing and ensuring the accuracy of the test.

[0059] The above specific embodiments further illustrate the purpose, technical solution, and beneficial effects of the present invention. It should be understood that the above are merely specific embodiments of the present invention and do not limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention are included within the protection scope of the present invention.
