Description

Technical Field

[0001] The utility model relates to the technical field of human exhaled gas detection, in particular to an on-line detection device for endogenous markers in human exhaled gas. Background Art

[0002] Endogenous compounds in human exhaled breath, including inorganic gases (such as NO and CO) and VOCs (such as isoprene, ethane, pentane, and acetone), are metabolic products of human tissues. By analyzing the components and detecting the concentrations of endogenous markers, relevant information on human tissue metabolism and health status can be obtained non-invasively, which helps to clarify the corresponding physiological processes, disease occurrence, disease progression, and pharmacological responses. Therefore, the detection of human exhaled gas is essential in the process of modern medical testing, and special detection equipment is required for detection.

[0003] However, the existing online detection device for endogenous markers in human exhaled gas does not have the function of discharging the exhaled gas after detection when detecting exhaled gas. Therefore, some of the exhaled gas detected by the former may remain inside the device. When performing the latter detection, the remaining part of the former exhaled gas will cause certain errors in the latter detection, affecting the detection quality. In this regard, this design proposes an online detection equipment for endogenous markers in human exhaled gas. Utility Model Content

[0007] In one example, a one-way valve is installed on the top of the tap, an air inlet pipe is inserted through one end of the tap, and an exhaust pipe is inserted through the other side of the tap.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described 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.

[0021] See also Figure 1-5 The utility model provides a technical solution: an online detection device for endogenous markers in human exhaled breath, comprising a storage box 1, a mounting plate 2, a detection mechanism 3 mounted on the upper end of the mounting plate 2, and a lifting mechanism 4 inside the storage box 1;

[0022] The detection mechanism 3 includes a detector body 301 mounted on the mounting plate 2, a first connecting pipe 302 is inserted into one side of the detector body 301, a support frame 303 is fixedly provided on one side of the top of the mounting plate 2, and the inner wall of the top of the support frame 303 is fixedly connected to the outer wall of the first connecting pipe 302, an air pump 304 is installed on one side of the detector body 301, a support shaft 305 is installed on the top of the mounting plate 2 on one side of the support frame 303, a tap 306 is fixed on the top of the support shaft 305, and the tap A conduit 307 is inserted into one side of 306, and one end of the conduit 307 is inserted into the output end of the vacuum pump 304. One side of the vacuum pump 304 is connected to a second connecting pipe 308 through the inner wall of the detector body 301. One end of the first connecting pipe 302 and one end of the second connecting pipe 308 are fixed with a mounting plate 309. During installation, the first connecting pipe 302 is supported by the support frame 303, and the tap 306 is supported by the support shaft 305, so that it is more stable during use.

[0023] A one-way valve 310 is installed on the top of the tap 306. An air inlet pipe 311 is inserted into one end of the tap 306, and an exhaust pipe 312 is inserted into the other side of the tap 306.

[0024] When in use, the one-way valve 310 is rotated to open the passage between the air inlet pipe 311 and the tap 306, so that the passage between the air outlet pipe 312 and the tap 306 is closed. The user exhales after connecting the exhalation device to the air inlet pipe 311, so that the exhaled gas enters the first connecting pipe 302 through the tap 306. The first connecting pipe 302 and the second connecting pipe 308 are sealed and installed in the detection structure inside the detector body 301 through the mounting plate 309, so that the exhaled gas enters the detector body 301 for detection. After the data is generated, the device is started. The air pump 304 draws the exhaled gas out through the second connecting tube 308 and directs it into the tap 306 via the conduit 307. At this time, the one-way valve 310 rotates in the opposite direction, opening the passage between the exhaust pipe 312 and the tap 306 and closing the passage between the intake pipe 311 and the tap 306. This allows all the test gas to be discharged through the exhaust pipe 312 for disposal. This reduces the risk of exhaled gas remaining in the detector body 301, allowing users to more accurately detect endogenous markers and improving the quality of the device's exhaled gas detection.

[0025] Furthermore, the lifting mechanism 4 includes a first limiting slide groove 401 opened on both sides of the inner wall of the storage box 1, and the inner walls of the two first limiting slide grooves 401 are both slidably provided with a first slider 402, and the first limiting slide groove 401 has a limiting effect on the first slider 402, so that it cannot detach.

[0026] A cross link 403 is rotatably provided at one end of both sides of the inner wall of the storage box 1, and one end of the bottom of the two cross links 403 is rotatably connected to one side of the two first sliders 402 respectively. A rotating shaft 404 is rotatably connected between the two cross links 403. When in use, the protective cover 5 is opened, and the electric telescopic rod 405 is started to extend and retract to push the rotating shaft 404, thereby pushing the cross links 403 on both sides to start folding. During the folding process, its support height increases, thereby lifting the mounting plate 2, and at the same time, the height of the detection mechanism 3 is also increased, which is convenient for adjustment according to testers of different heights, making it more convenient and comfortable to use;

[0027] Furthermore, an electric telescopic rod 405 is rotatably installed at the lower end of one side of the inner wall of the storage box 1, and the output end of the electric telescopic rod 405 is rotatably connected to one side of the rotating shaft 404. Second limiting sliding grooves 406 are provided on both sides of the bottom of the mounting plate 2. The inner walls of the two second limiting sliding grooves 406 are slidably provided with second sliders 407, and during the folding process of the cross link 403, one end of the top and the bottom are rotatably connected to the inner side of the storage box 1 and the mounting plate 2 respectively, and the other ends of the top and the bottom are respectively in the first sliding grooves. The first and second sliders 402 and 407 rotate on the support rails 404 and 405, and the first and second sliders 402 and 407 move as they slide in the first limiting slots 401 and the second limiting slots 406. At the same time, when the electric telescopic rod 405 is extended or retracted, the rotating shaft 404 rotates along with the movement of the cross link 403. Therefore, when the cross link 403 is lifting or lowering the mounting plate 2, there is no motion interference between the cross link 403 and the mounting plate 2, the rotating shaft 404 and the electric telescopic rod 405, and the lifting or lowering adjustment can be performed smoothly.

[0028] Furthermore, one end of the top of the two cross links 403 is rotatably connected to the two sides of the bottom of the mounting plate 2, and the other end of the top of the two cross links 403 is rotatably connected to one side of the two second sliders 407. A protective cover 5 is hinged on one side of the top of the storage box 1. When the detection device is not in use, the mounting plate 2 is lowered to the lowest point, and then the protective cover 5 is covered to store the detection mechanism 3 and the lifting mechanism 4 in the storage box 1, which is convenient for carrying and transporting.
