[0002] Helicobacter pylori is a kind of fungus belonging to the kingdom of bacteria, class ε-Proteobacteria, order Campylobacteriales, family Campylobacteraceae. It is also called Helicobacter pylori, Helicobacter pylori, and Helicobacter pylori is abbreviated as HP. This fungus was first discovered by Swedish scholars from the culture of human gastric mucosa specimens. It is also a hot topic of domestic research in recent years. Helicobacter pylori examination is a common examination item in gastroenterology.
[0003] In the prior art, the 14C-urea breath test in non-invasive examination is often used. The solution is placed in a gas collection bottle, and then the patient blows air below the liquid level of the solution to collect the breath sample using the solution. During the breath sampling, the continuous blowing is laborious, and the problem of inhaling the solution back during ventilation is easy to occur. Therefore, we propose a breath sampling device for gastrointestinal examination. Utility Model Content
[0004] The purpose of the utility model is to provide a breath sampling device for gastrointestinal examination, which can be connected to the air outlet pipe on the bottle cap by arranging a vacuum device. When blowing air into the gas collecting bottle through the air blowing pipe, the vacuum device slowly draws out the gas inside the gas collecting bottle, making it easier for the tester to blow gas into the air blowing pipe. Under the action of the float and the ring, reverse inhalation can be avoided so that the solution is sucked out from the air blowing pipe, making it easier to collect exhaled gas, thereby solving the problems raised in the background technology.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a breath sampling device for gastrointestinal examination, comprising a base and an air suction device, the air suction device being fixed on the side surface of the base, and a hose connected to the negative pressure pump inside the air suction device is connected above the air suction device; a branch groove is opened on the surface of the base on the side of the air suction device, and a gas collecting bottle is supported and placed in the branch groove, and a bottle cap is connected to the top of the gas collecting bottle by screwing, and an air outlet pipe connected to the inside of the gas collecting bottle is connected to the surface of one side of the bottle cap; an air blowing pipe that penetrates into the gas collecting bottle is connected to the other side of the bottle cap, and the bottom of the air blowing pipe is laterally bent and placed in the gas collecting bottle, and a plurality of air holes connected to the inside of the air blowing pipe are evenly arranged on the bottom surface of the air blowing pipe, and two connecting ropes are fixed longitudinally in the middle of the air blowing pipe, a floating ball is supported inside the air blowing pipe above the connecting rope, and a ring is fixed inside the air blowing pipe above the floating ball, and the inner diameter of the ring is smaller than the diameter of the floating ball.

DETAILED DESCRIPTION
[0023] See also Figure 1-3 The utility model provides a technical solution: a breath sampling device for gastrointestinal examination, comprising a base 1 and a vacuum device 2, a circular support groove 11 being provided on the left side surface of the base 1, a gas collecting bottle 3 being supported and placed on the surface of the base 1 through the support groove 11, a rubber block 111 being evenly fitted and fixed on the inner wall surface of the support groove 11, the rubber block 111 on the inner wall of the support groove 11 being in contact with the outer surface of the gas collecting bottle 3, and the gas collecting bottle 3 being able to be locked in the support groove 11 on the surface of the base 1.
[0024] A bottle cap 31 is connected to the top of the gas collecting bottle 3 by screwing. The inner circle of the bottle cap 31 and the upper outer circle of the gas collecting bottle 3 are both provided with threads. The bottle cap 31 is screwed to the upper outer circle of the gas collecting bottle 3 by threads. The bottle cap 31 can be unscrewed from the top of the gas collecting bottle 3, and then the collection solution can be added to the gas collecting bottle 3. After the collection is completed, the bottle cap 31 can be unscrewed first and then the solution can be taken out.
[0025] The left side of the bottle cap 31 is connected with a blowing tube 4 that penetrates into the gas collecting bottle 3. The bottom of the blowing tube 4 is bent transversely, and the bottom of the blowing tube 4 is transversely placed below the gas collecting bottle 3. The bottom surface of the blowing tube 4 is evenly provided with a plurality of air holes 42 that are connected to the inside thereof. The outer ring at the end of the blowing tube 4 is sleeved with a first sealing cover 41. The inner surface of the first sealing cover 41 is tightly pressed against the outer surface of the blowing tube 4. When collecting exhaled air, the first sealing cover 41 is first removed, and then the gas is exhaled into the blowing tube 4, and then enters into the solution from the even air holes 42 to react with the solution for collection.
[0026] The right side surface of the bottle cap 31 is connected to an outlet pipe 5 connected to the inside of the gas collecting bottle 3. A second sealing cover 51 is sleeved on the outer ring of the end of the outlet pipe 5. The inner surface of the second sealing cover 51 is tightly against the outer surface of the outlet pipe 5. A vacuum device 2 is fixed to the right side surface of the base 1. A negative pressure pump and a battery for powering the vacuum device 2 are installed inside the vacuum device 2. A hose 21 connected to the negative pressure pump inside the vacuum device 2 is connected to the top of the vacuum device 2. When collecting exhaled air, first unplug the second sealing cover 51, then put the hose 21 on the outer ring of the outlet pipe 5 and connect it to it, start the vacuum device 2 to extract the gas inside the gas collecting bottle 3, so that the tester can exhale gas into the gas collecting bottle 3 more easily.
[0027] Two connecting ropes 44 are fixed longitudinally in the middle of the air blowing tube 4, and a floating ball 43 is supported inside the air blowing tube 4 above the connecting ropes 44. The floating ball 43 is supported above the two connecting ropes 44. A ring 45 is fixed inside the air blowing tube 4 above the floating ball 43. The inner diameter of the ring 45 is smaller than the diameter of the floating ball 43. When air is accidentally inhaled, under the action of the airflow and the buoyancy of the solution entering the air blowing tube 4, the floating ball 43 can be pressed against the bottom of the ring 45 to block the air blowing tube 4, thereby preventing the solution from being sucked out in the reverse direction.
[0028] When in use, unscrew the bottle cap 31 on the top of the gas collecting bottle 3, and then add the sampling and testing solution into the gas collecting bottle 3, so that the solution spreads to the middle position inside the gas collecting bottle 3, and then screw the bottle cap 31 on the top of the gas collecting bottle 3 by screwing, so that the lower horizontal part of the air blowing tube 4 is completely immersed in the solution, and the float 43 part is placed above the liquid surface of the solution, and then respectively pull down the first cover 41 and the second cover 51 on the air blowing tube 4 and the air outlet pipe 5, so that the end of the hose 21 is covered on the outer ring of the air outlet pipe 5, start the vacuum device 2 and hold the air blowing tube 4 in the mouth and blow air into it. Since the vacuum device 2 slowly extracts the gas in the gas collecting bottle 3 through the hose 21, This makes it effortless for the tester to blow air from the air blowing tube 4, and finally the air is discharged from the evenly distributed air holes 42 into the solution, where it reacts with the solution and is collected. When the tester inhales air accidentally, the float 43 will rise under the action of the air flow, and the solution will also rise when it enters the air blowing tube 4, so that the float 43 can be pressed against the lower surface of the ring 45 to seal it, thereby avoiding the accidental aspiration of the solution. When the sampling is completed, the vacuum device 2 is stopped and the hose 21 is removed. Then, the first cover 41 and the second cover 51 are respectively put on the outer rings of the air blowing tube 4 and the air outlet pipe 5 to seal them, and then the gas collecting bottle 3 is removed from the branch groove 11 for testing.
