Description

Technical Field

[0001] The utility model relates to the technical field of Helicobacter pylori sampling, in particular to an automatic blocking type Helicobacter pylori breath detection sampler. Background Art

[0002] Helicobacter pylori is a bacterium that parasitizes in the stomach, mainly in the pyloric part of the stomach, so it is called Helicobacter pylori. After infection, it mainly causes diseases such as chronic gastritis and peptic ulcer. It is closely related to diseases such as gastric cancer and gastric mucosa-associated lymphoid tissue lymphoma. It is listed as a Class I biological carcinogen by the World Health Organization. The biggest advantage of the breath test is its accuracy. There are many methods for detecting Helicobacter pylori, such as serum antibody test, fecal antigen test, carbon 13 or carbon 14 breath test, rapid urease test, gastric mucosal endoscopic biopsy staining microscopy, bacterial culture, etc. Among them, carbon 13 or carbon 14 breath test is simple to operate, non-invasive, and highly accurate. It is recognized by the medical community as the gold standard for detecting Helicobacter pylori.

[0003] When sampling for Helicobacter pylori breath detection, if the subject's breath is insufficient and needs to be exchanged or blown, the subject's mouth will leave the air inlet of the collector, causing partial exchange of the internally collected gas with the outside air, which will affect the accuracy of the test data. Therefore, we propose an automatic blocking Helicobacter pylori breath detection sampler. Utility Model Content

[0004] The utility model aims to provide an automatic blocking type Helicobacter pylori breath detection sampler to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an automatic blocking Helicobacter pylori breath detection sampler, comprising a sampler body, a color display window, an air inlet pipe, an air blowing nozzle and a blocking block, wherein the color display window is arranged on the surface of the sampler body, the air inlet pipe is arranged at the top of the sampler body, and an air inlet is arranged at the top of the air inlet pipe, the blocking block is arranged at the top of the air inlet pipe, and the blocking block is tightly fitted with the air inlet, and an arc-surface protrusion is arranged on the top of the blocking block, the air blowing nozzle is sleeved on the outside of the air inlet pipe, and the outer wall of the top of the air blowing nozzle is provided with external threaded strips at equal intervals, and a positioning slot is arranged on the inner wall of the bottom of the air blowing nozzle, the outside of the sampler body is sleeved with a sampler shell, and a circular opening groove is arranged on the outer wall of the sampler shell, and the circular opening groove corresponds to the color display window.

[0006] Preferably, a sealing cover is mounted on the top of the blowing nozzle, and the inner wall of the sealing cover is provided with internal thread grooves with equal spacing, and the internal thread grooves are tightly engaged with the external thread strips for connecting the sealing cover and the blowing nozzle.

[0007] Preferably, a spring is fixed to the bottom end of the blocking block, and the bottom end of the spring is fixedly connected to the inner wall of the bottom of the air inlet pipe to provide elastic supporting force for the blocking block.

[0008] Preferably, a sealing ring is adhered to the edge of the top of the blocking block to further improve the sealing performance of the blocking.

[0009] Preferably, a non-slip rubber ring is adhered to the outer wall of the air inlet pipe at the position of the positioning slot, and the non-slip rubber ring fits tightly with the positioning slot, so that the blowing nozzle is tightly connected to the air inlet pipe.

[0010] Preferably, a sealing groove is provided on the inner wall of the air intake pipe at the position of the sealing ring, and the sealing ring fits tightly with the sealing groove, so as to facilitate the positioning of the sealing ring.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] By providing an air inlet pipe, an air inlet, a spring, a blocking block, a curved protrusion, a sealing ring, and a sealing groove, air is blown through the blowing nozzle. When blowing, under the push of the gas, the blocking block overcomes the elasticity of the spring and moves downward. At this time, the blocking block drives the curved protrusion to move away from the air inlet, and the gas enters the sampler body through the air inlet pipe. When ventilating, the blocking block returns to its original position under the elastic action of the spring and blocks the air inlet. At the same time, the sealing ring on the top of the blocking block is stuck in the sealing groove on the inner wall of the air inlet pipe, thereby improving the sealing of the blocking block. The structure realizes the automatic sealing function. When the subject's breath is insufficient and needs to be ventilated or the blowing is completed, the gas collected in the sampler body will not escape, and will not form a partial exchange with the outside air, thereby ensuring the accuracy of the detection data.

[0025] A sealing ring 12 is glued to the edge of the top of the blocking block 7, which further improves the sealing performance of the blocking;

[0026] When blowing, under the push of gas, the blocking block 7 overcomes the elasticity of the spring 6 and moves downward. At this time, the blocking block 7 drives the arc-surface protrusion 8 to move away from the air inlet 9, and the gas enters the sampler body 1 through the air inlet pipe 3. When exhaling, the blocking block 7 returns to its original position under the elastic action of the spring 6 and blocks the air inlet 9.

[0029] When the embodiment of the present application is used: first, the Helicobacter pylori breath detection sampler is mainly composed of a sampler body 1, a color window 2, an air inlet pipe 3, an air blowing nozzle 4, and a sealing cover 5. The air blowing nozzle 4 is sleeved on the outside of the air inlet pipe 3, and the anti-slip rubber ring 11 fits tightly with the positioning card slot 10, so that the air blowing nozzle 4 will not loosen and fall off. The sealing cover 5 is threadedly connected to the air blowing nozzle 4 through the internal thread groove 501 and the external thread strip 401, and the air blowing nozzle 4 can be sealed. When in use, the subject First, swallow the urea capsule marked by the carbon sampler shell 14 with warm water and sit for fifteen minutes. Then, install the sampler body 1 in the sampler shell 14. Next, unscrew the sealing cover 5 and blow air through the blowing nozzle 4. When blowing, under the push of the gas, the blocking block 7 overcomes the elasticity of the spring 6 and moves downward. At this time, the blocking block 7 drives the arc-surface protrusion 8 to move away from the air inlet 9, and the gas enters the sampler body 1 through the air inlet pipe 3. Slowly blow for three to five seconds. The air inlet 9 is blocked by the sealing ring 12 on the top of the sealing block 7, and the sealing performance of the sealing block 7 is improved.
