[0018] As Figure 1-2As shown in the figure, an in vitro gastrointestinal disease etiology analysis device includes a housing 10. Inside the housing 10, there is a closed gas channel 20. Both ends of the gas channel 20 extend to the end faces of the housing 10 and form an air inlet 21 and an air outlet 22 respectively. One or more sensors 30 are arranged in the gas channel 20. Each sensor 30 is electrically connected to a circuit board 40 arranged in the housing 10. Each sensor 30 can detect the content of a specific substance in the gas channel 20, convert it into an electrical signal and then feedback it to the circuit board 40. The circuit board 40 is electrically connected to an external electronic device through a connecting component 41.

[0019] The using process of the present utility model is as follows: First, electrically connect the connecting component 41 with an electronic device (power supply device and / or result display device), start the present utility model. Then, the tester blows air into the air inlet 21. The gas enters the gas channel 20. The sensor 30 detects the content of a specific gas in the channel and feeds the result back to the circuit board 40. After processing, the circuit board 40 outputs the electrical signal from the connecting component 41. The gas in the gas channel 20 is discharged through the air outlet 22.

[0020] Since it has been confirmed that some gastrointestinal diseases will show the phenomenon that specific gases reflux into the oral cavity through the esophagus, therefore, by detecting the content of this specific gas in the gas exhaled from the tester's oral cavity, the type and severity of the tester's gastrointestinal diseases can be assisted in determining, and the detection results can be intuitively displayed through a display device, which is convenient for medical staff to conduct a preliminary screening of the etiology of gastrointestinal diseases, enabling some suspected or mild patients to be exempted from further detailed endoscopic examinations, reducing the pain of the tester and improving the detection efficiency; it can enable some suspected or mild patients to avoid further detailed endoscopic examinations, reducing the pain of the tester and improving the detection efficiency.

[0021] Furthermore, the gas channel 20 is formed by buckling two matching rubber shells. At both ends of each rubber shell, there is a first positioning member 23. On the housing 10, there are several second positioning members 11 that are adapted to the first positioning members 23 one by one. Inside the gas channel 20, a one-way plate 24 is hinged beside the air inlet 21. The one-way plate 24 can be flipped towards the gas channel 30 under the push of air flow and can fall down to block the gas channel 20 when there is no obvious air flow. An outer rubber sleeve 50 is also sleeved on the air inlet 21. The rubber sleeve 50 has a lip-shaped structure. Its outer ring is embedded on the outer walls of the upper cover 12 and the lower cover 13, and its inner wall extends into the air inlet 21.

[0022] For the convenience of production and assembly, in the present utility model, the gas flow channel 20 is formed by buckling two rubber shells. The sensor 30 is fixed on one rubber shell. The rubber shell is detachably fixed on the housing 10 through the positioning members at both ends, and the installation is very convenient. The one-way plate 24 can block the gas channel 20 when the present utility model is not in use, slowing down the loss of the external environment to the internal circuit board and various components thereon.

[0023] Furthermore, a starting component 42 and a warning component 43 are also installed on the circuit board 40, and the housing 10 is provided with hole grooves that can avoid the connecting component 41, the starting component 42, and the warning component 43 one by one.

[0024] During use, the connecting component 41 is connected to supply power to the circuit board 40, the warning component 43 lights up, and the starting component 42 is pressed to turn on the working mode of the present utility model, which is convenient to operate.

[0025] Furthermore, the housing 10 includes an upper cover 12, a lower cover 13, and two side covers 14 that can be matched and fastened. The upper cover 12 is provided with a first hole groove 15 adapted to the warning component 43, and each side cover 14 is provided with a second hole groove 16 adapted to the connecting component 41 or the starting button 42.

[0026] In this embodiment, in order to reduce the influence of the outside world on the circuit board 40 and the chips and electronic components thereon and ensure its sensitivity to gas, a cover plate 17 is also fastened on each side cover 14, and the cover plate 17 is also provided with a second hole groove 16 that matches; at the same time, in order to avoid the influence of the device falling on the function of the internal circuit board 40, an anti-slip groove 18 adapted to the index finger is also provided at the bottom end of the lower cover 13, and the upper cover 12 is set to an arc shape adapted to the palm.

[0027] The above does not impose any limitation on the technical scope of the present utility model. Any modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present utility model still fall within the scope of the technical solution of the present utility model.
