Description

Technical Field

[0001] The utility model belongs to the technical field of auxiliary equipment for breath test testers and relates to a gas collecting component for breath test testers. Background Art

[0002] Helicobacter pylori ("H. pylori") affects approximately two-thirds of the world's population, causing chronic gastritis and most peptic ulcers, and is the leading cause of gastric cancer, the third leading cause of cancer death worldwide. Although the prevalence of H. pylori has been declining in Western countries since its discovery in 1982, it remains at very high levels in Eastern Europe, Asia, and the Asia-Pacific region, affecting more than 80% of young adults and children. An important property of H. pylori is its abundant urease, which hydrolyzes urea. When H. pylori in the stomach is exposed to urea, it converts the urea into CO2 and NH3, both of which travel through the bloodstream to the lungs and are exhaled in the exhaled breath. The decomposition of urea is described by the following equation: CO(NH2)2 + H2O - Urease → CO2 + 2NH3.

[0003] The urea breath test is a non-invasive method for detecting Helicobacter pylori. Two air collection bags and a urea capsule marked with C are required for the test. During the test, the subject needs to blow into one air collection bag after fasting or two hours after eating, and then blow into another air collection bag half an hour after taking the urea capsule orally. Finally, the gas in the two air collection bags is tested by the breath tester to determine whether Helicobacter pylori exists.

[0004] During the test, medical staff need to label the two gas collection bags to confirm that the two gas collection bags belong to the same subject. However, when the number of subjects is large, after collecting the gas collection bags of a large number of subjects, it is necessary to find the two gas collection bags corresponding to the same subject from the large number of gas collection bags when using the breath test tester. This process will take a certain amount of time and affect the detection efficiency. Utility Model Content

[0005] The utility model aims to solve the above problems and provides a gas collecting assembly for a breath test instrument.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A gas collecting assembly for a breath test tester includes two gas collecting bags and a gas collecting panel. The two gas collecting bags are fixed on the back of the gas collecting panel. A mouthpiece is provided on the front of the gas collecting panel. A single-inlet and double-outlet flow channel structure connecting the mouthpiece and the two gas collecting bags is also provided inside the gas collecting panel. A press-type sealing valve structure is also provided at the gas outlet end of the single-inlet and double-outlet flow channel structure connecting the two gas collecting bags.

[0008] In the above-mentioned air collection assembly for the breath test tester, the single-inlet and dual-outlet flow channel structure includes an air inlet end connected to the mouthpiece and two air outlet ends respectively connected to the air collection bags, and the two air outlet ends are both connected to the air inlet end and are respectively arranged on both sides of the air inlet end.

[0009] In the above-mentioned gas collecting assembly for the breath test tester, the push-type sealing valve structure includes a valve core which is vertically inserted into the gas collecting panel and can block both sides of the gas outlet end, and a one-way driving member which can drive the valve core to move vertically upward. The valve core is provided with a connecting flow channel which connects both sides of the gas outlet end when the valve core is pressed downward.

[0010] In the above-mentioned gas collection assembly for the breath test tester, the one-way driving member includes an elastic button with a hemispherical cross-section, the elastic button is fixed to the front of the gas collection panel and the top of the valve core is fixedly connected to the elastic button.

[0011] In the above-mentioned gas collecting assembly for the breathalyzer tester, the elastic button is made of rubber.

[0012] In the above-mentioned gas collection assembly for the breath test tester, a detection port is arranged at one end of the gas collection bag away from the gas collection panel and a screw cap is screwed onto the detection port.

[0013] In the above-mentioned gas collecting assembly for the breathalyzer tester, the connection between the gas outlet and the gas inlet is further provided with an inclined connection section.

[0014] In the above-mentioned gas collecting assembly for the breathalyzer tester, the connection between the connecting section and the air inlet end is lower than the connection between the connecting section and the air outlet end.

[0015] In the above-mentioned gas collecting assembly for the breathalyzer tester, the cross section of the gas collecting panel is I-shaped.

[0016] In the above-mentioned air collection assembly for the breathalyzer tester, the mouthpiece and the air collection panel are integrally arranged.

[0017] Compared with the existing technology, the advantages of the utility model are:

[0018] 1. The utility model integrates two air collecting bags into the air collecting panel. Air can be blown into the two air collecting bags respectively through the single-inlet and double-outlet flow channel structure on the mouthpiece and the air collecting panel. The two integrated air collecting bags do not need to be manually paired when tested by a breathalyzer, which can save time for pairing air collecting bags for testing. The same subject only needs to be labeled, which can reduce the workload of medical staff. The push-type sealing valve structure arranged on the air outlet can achieve that the subject can only blow air into one air collecting bag at a time.

[0019] 2. When the patient is blowing air, pressing the valve core downwards can connect the two ends of the air outlet to the connecting channel so that gas can be collected in the air collecting bag corresponding to the valve core. After the blowing is completed, the subject stops pressing the valve core, and the valve core is reset under the action of the one-way drive component. The valve core automatically moves to the misalignment between the connecting channel and the air outlet, and the valve core blocks the air outlet, thereby preventing other leakage in the air collecting bag.

[0027] The utility model integrates two air collecting bags on the air collecting panel 2, and air can be blown into the two air collecting bags respectively through the mouthpiece 3 and the single-inlet and double-outlet flow channel structure 4 on the air collecting panel 2. The two integrated air collecting bags do not need to be manually paired when passing the breath test detector for detection, which can save the time of pairing the air collecting bags for the detection work, and the same subject only needs to be labeled, which can reduce the workload of medical staff. The push-type sealing valve structure 6 arranged on the air outlet end 5 can achieve that the subject can only blow air into one air collecting bag at a time.

[0028] Specifically, the single-inlet and double-outlet flow channel structure 4 includes an air inlet end 7 connected to the mouthpiece 3 and two air outlet ends 5 respectively connected to the air collection bag 1, and the two air outlet ends 5 are both connected to the air inlet end 7 and are respectively arranged on both sides of the air inlet end 7. The subject can blow air into the mouthpiece to blow the gas into the air collection bag through the air inlet end and the air outlet end.

[0029] Specifically, the push-type sealing valve structure 6 includes a valve core 8 vertically inserted into the gas collection panel 2 and capable of blocking both sides of the gas outlet 5, and a one-way driving member 9 capable of driving the valve core 8 to move vertically upward. The valve core 8 is provided with a connecting flow channel 10 that connects both sides of the gas outlet 5 when the valve core 8 is pressed downward. When the patient blows air, pressing the valve core 8 downward can make the connecting flow channel 10 connect both ends of the gas outlet 5 so that gas can be collected from the gas collection bag corresponding to the valve core. After the blowing is completed, the subject stops pressing the valve core, and the valve core is reset under the action of the one-way driving member. The valve core automatically moves to the misalignment between the connecting flow channel 10 and the gas outlet, and the valve core blocks the gas outlet, thereby preventing other leakage in the gas collection bag.

[0030] Specifically, the one-way driving member 9 includes an elastic button 11 with a hemispherical cross section, which is fixed to the front of the gas collecting panel 2 and the top of the valve core 8 is fixedly connected to the elastic button 11, and the elastic button 11 is made of rubber. The elastic button made of rubber can drive the valve core to move vertically upward when the subject does not press the valve core, so that the valve core is in a state of blocking the gas outlet.

[0031] Specifically, the end of the gas collection bag 1 away from the gas collection panel 2 is provided with a detection port 12 and a screw cap 13 is screwed on the detection port 12.
