Description

Technical Field

[0001] The present invention relates to the technical field of disease diagnosis, and particularly to a disease diagnostic instrument based on breath gas analysis. Background Art

[0002] In the medical field, the accurate diagnosis of diseases is crucial for the effective treatment and rehabilitation of patients. Traditional disease diagnosis methods are diverse, including blood tests, imaging examinations, etc. However, these methods often have certain limitations. For example, blood tests require collecting patients' blood, causing some pain to patients, and the testing process is relatively complex and time-consuming. Imaging examination equipment is expensive and has limited sensitivity for detecting some early diseases. With the continuous in-depth medical research, breath gas analysis, as an emerging diagnostic technology, has gradually attracted attention. The human breath gas contains various biomarkers related to health conditions. By analyzing these biomarkers, information about the physiological and pathological states of the human body can be obtained. For example, the content changes of certain volatile organic compounds (VOCs) may be closely related to specific diseases such as cancer, lung diseases, diabetes, etc. Breath gas analysis has the advantages of non-invasive, convenient, and fast, and can detect potential signs of diseases at an early stage, providing strong support for the early diagnosis and treatment of diseases.

[0003] However, there are still many problems in the current disease diagnosis technology based on breath gas analysis. On the one hand, the existing breath gas collection and detection equipment has deficiencies in working efficiency. Many devices require patients to cooperate for a long time, and each detection can only analyze a small amount of gas samples, resulting in a slow detection process and unable to meet the needs of rapid clinical diagnosis. For example, some traditional diagnostic instruments lack effective temporary storage and rapid analysis mechanisms when collecting breath gas, making the entire diagnostic process cumbersome and wasting a large amount of time and medical resources. On the other hand, the hygiene and safety issues of the equipment cannot be ignored. During repeated use, the gas collection and temporary storage components are easily contaminated. If they cannot be cleaned and disinfected in a timely and effective manner, cross-infection is very likely to occur, seriously affecting the accuracy of the detection results. For example, components such as gas storage tanks may interfere with subsequent detections after multiple uses, resulting in misdiagnosis or missed diagnosis. Summary of the Invention

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

[0007] A self-cleaning mechanism is arranged on the surface of the functional box to avoid cross-infection during use of the gas storage tank and affect the accuracy of the detection results by cleaning and disinfecting the inner surface of the gas storage tank;

[0008] The self-cleaning mechanism includes: a first switching motor and a second switching motor, which 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 pipe.

The upper end of the cleaning pipe is fixedly connected to one end of a fluid input pipe, and the other end of the fluid input pipe is fixedly connected to a solenoid valve. An external joint is fixedly installed on the outer surface of the upper end of the functional box, and a communication groove is provided inside the surface of the functional box between the external joint and the solenoid valve. A diversion groove is provided inside the side surface of the functional box, and a discharge joint is fixedly installed on the outer surface of the functional box opposite to the diversion groove;

[0009] One end of the outer surface of the closing plate is provided with an exhaust hole, and an installation box is fixedly arranged on the upper surface of the closing plate above the exhaust hole. A exhaust pipe is fixedly arranged on the outer surface of the installation box. A rotating impeller is installed inside the installation box, and one end of the rotating shaft of the impeller penetrates through the outer side surface of the installation box. One end of the rotating shaft of the impeller located outside the installation box is fixedly connected with a shielding plate. A shielding sensor is fixedly installed on the outer side surface of the installation box.

The lower surface of the closing plate is fitted with the upper surface of the central seat, and the outer side surface of the closing plate is fitted with the inner side surface of the closing cylinder. The upper end of the closing cylinder is fitted with the inner bottom surface of the function box.

[0011] Adopting the above technical solution, the entire dynamic detection mechanism can form a relatively closed and stable spatial structure. This tightly fitted design can effectively prevent the leakage of breathing gas, ensure that all the collected gas can be accurately detected, avoid the influence of gas escape on the accuracy of the detection result, and at the same time ensure the stability of the central seat during rotation, enabling it to smoothly drive the gas storage grooves to collect and temporarily store gas.

[0012] Preferably, the partition plates are evenly distributed on the upper surface of the closing plate, and the partition plates and the third relief grooves are arranged in one-to-one correspondence. The partition plates are located between two third relief grooves. The upper end of the gas storage groove is located between two partition plates. One end of the second air inlet joint penetrates through the inner side surface of the closing cylinder, and the second air inlet joint is arranged opposite to the first relief groove.

[0013] Adopting the above technical solution, the partition plates can isolate the gas in different gas storage grooves, avoiding the mutual mixing of the gas collected in different batches and interfering with the detection result. The positive setting of the second air inlet joint and the first relief groove, and the cooperation of related structures enable the breathing gas to smoothly enter the gas storage groove from the second air inlet joint through the first relief groove, ensuring the smoothness of the gas collection path and improving the efficiency and accuracy of the equipment for collecting gas.

[0014] Preferably, the cleaning pipe is designed in a columnar shape, and holes are evenly arranged on the outer side surface of the cleaning pipe. The cleaning pipe is arranged opposite to the second relief groove.

[0015] Adopting the above technical solution, the cleaning pipe with a columnar design and evenly arranged holes on the outer side can evenly spray the input cleaning liquid or drying gas onto the inner side surface of the gas storage groove when it is arranged opposite to the second relief groove, ensuring that the cleaning and drying work are carried out comprehensively and evenly, effectively removing the residual gas and impurities in the gas storage groove, avoiding cross-infection caused by incomplete cleaning, ensuring the hygiene condition of the equipment, and thus guaranteeing the accuracy of the detection result.

[0016] Preferably, the ultraviolet lamp tube is arranged opposite to the second relief groove, and the outer diameters of the ultraviolet lamp tube and the cleaning tube are smaller than the groove width of the second relief groove.

[0017] With the above technical solution, when the air storage tank rotates to the corresponding position, the ultraviolet lamp tube being arranged opposite to the second relief groove can directly disinfect it to ensure the disinfection effect. The outer diameters of the ultraviolet lamp tube and the cleaning tube being smaller than the groove width of the second relief groove facilitates their entry into the area where the air storage tank is located through the second relief groove for cleaning and disinfection work.

[0018] Preferably, the second relief groove is arranged opposite to the diversion groove, and one end of the diversion groove facing the closed cylinder is in contact with the outer surface of the closed cylinder.

[0019] With the above technical solution, the waste liquid or waste gas generated during the cleaning and disinfection of the air storage tank can smoothly enter the diversion groove through the second relief groove and then be discharged from the discharge joint, ensuring the cleanliness inside the device, avoiding interference with subsequent detections caused by the residue of waste liquid and waste gas, maintaining the normal operating environment of the device, and guaranteeing the smooth progress of the detection work.

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

[0021] With the above technical solution, a smooth discharge channel is provided for the excess gas exhaled by the patient, ensuring the stability of the gas pressure inside the function box and preventing the detection process from being affected by gas accumulation. At the same time, it ensures smooth gas circulation inside the device, facilitating the collection of respiratory gases and the normal progress of the detection work, and avoiding detection errors caused by gas blockage.

[0022] Preferably, the outer surface of the impeller is in contact with the inner surface of the installation box, and one end of the occlusion sensor is arranged opposite to the baffle plate.

[0023] With the above technical solution, the close fit between the impeller and the installation box can ensure stable rotation under the push of gas. By monitoring the occlusion frequency of the baffle plate rotating with the impeller to the occlusion sensor, 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 air storage tank, ensuring that the air storage tank can collect enough exhaled gas from the patient, thereby guaranteeing the accuracy of the detection results.

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

[0025] 1. The central motor drives the central seat to rotate. The gas storage tanks evenly distributed on the central seat can sequentially collect and temporarily store the respiratory gas. During the rotation of the central seat, the gas in different gas storage tanks can be continuously transported to the gas detection module for detection, avoiding the disadvantages of traditional devices that detect a small amount of gas samples each time, realizing continuous detection of respiratory gas, greatly accelerating the overall working efficiency of the diagnostic instrument, meeting the needs of rapid clinical diagnosis, reducing the waiting time of patients and the waste of medical resources.

[0026] 2. The design of the self-cleaning mechanism effectively avoids the influence of cross-infection on the detection results. The first switching motor and the second switching motor can respectively control the cleaning pipe and the ultraviolet lamp tube to turn downward and work. The outer surface of the cleaning pipe is evenly provided with holes, and the cleaning liquid and dry gas respectively input by the two fluid input pipes can be evenly sprayed onto the inner surface of the gas storage tank to clean and dry it. The ultraviolet lamp tube can disinfect the cleaned gas storage tank, ensuring that the gas storage tank is always in a clean and sterile state, preventing residual gas and impurities from interfering with subsequent detections, thereby ensuring the accuracy of the detection results and reducing the probability of misdiagnosis and missed diagnosis.

[0027] 3. When the impeller is driven to rotate by the gas exhaled by the patient, the amount of gas exhaled by the patient is monitored by the shielding frequency of the shielding sensor by the shielding plate. When the amount of gas exhaled by the patient reaches the standard, the controller built in the display screen controls the central motor to start for switching the gas storage tank, so as to ensure that the gas storage tank can be filled with the gas exhaled by the patient to ensure the accuracy of the detection.
