Description

Technical Field

[0001] The utility model relates to the technical field of Helicobacter pylori sampling, in particular to a breath detection sampler with an anti-leakage structure. Background Art

[0002] In the fields of medical diagnosis and health monitoring, breath testing is becoming increasingly important as a non-invasive, convenient, and efficient testing method. By collecting and analyzing specific components or markers in a patient's exhaled air, this method can reveal physiological and pathological information related to various disease states, such as respiratory diseases, metabolic diseases, and even early screening for certain cancers. However, despite its many advantages, breath testing's accuracy is often limited by design flaws in traditional samplers.

[0003] Air leakage is a common problem faced by traditional breathalyzers. Due to factors such as improper internal channel design or aging sealing materials, gas samples are prone to leakage during the collection process. This leakage not only reduces the total sample volume but, more importantly, introduces outside air, diluting the target gas components in the sample and reducing their concentration, directly impacting the sensitivity and accuracy of subsequent analysis. Furthermore, air leakage can lead to sample contamination, further interfering with test results.

[0004] Based on this, the present invention proposes a breath detection sampler with an anti-leakage structure to solve the above technical problems. Utility Model Content

[0022] The following is a clear and complete description of the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only a part of the embodiments of the present invention, not all of them. 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.

[0023] like Figure 1-4 As shown, a breath detection sampler with an anti-leakage structure includes a collector body 1, an exhalation component 2 is detachably installed at one end of the collector body 1, a collecting component 3 is detachably installed at the other end of the collector body 1, a blocking component 4 is fixedly installed in the collector body 1, and a sealing component 5 is fixedly installed in the collecting component 3. An exhalation piece 2 is detachably installed at one end of the collector body 1. This design is convenient for patients to use, and is also easy to clean and replace, reducing the risk of cross infection. A collecting piece 3 is detachably installed at the other end of the collector body 1 for collecting the gas exhaled by the patient for subsequent testing. A sealing component 4 is fixedly installed in the collector body 1. When the patient is not exhaling, the component can automatically close the internal channel of the collector body 1 to prevent outside air from entering, thereby maintaining the purity of the collection environment. When the patient is exhaling, the internal channel of the collector body 1 can be automatically opened to facilitate the gas exhaled by the patient to pass through the collector body 1 into the collecting piece 3; a sealing component 5 is fixedly installed in the collecting piece 3. After collecting the gas sample, the component can quickly and effectively close the outlet of the collecting piece 3 to prevent the gas sample from leaking.

[0024] The blocking assembly 4 includes a central shaft 6, on which two baffles 7 are rotatably mounted. A mounting block 8 is fixedly mounted on the inner wall of the collector body 1, and the mounting block 8 is located behind the two baffles 7. A first spring 9 is fixedly mounted between the mounting block 8 and the two baffles 7, and one end of the two first springs 9 is fixedly mounted on the mounting block 8, and the other ends of the two first springs 9 are respectively fixedly connected to the two baffles 7; the blocking assembly 4 also includes two arc-shaped blocks 10, which are fixedly mounted on the inner wall of the collector body 1, and are located in front of the two baffles 7, and the two arc-shaped blocks 10 are respectively in contact with the two baffles 7. The central axis 6 serves as a support and rotation center, on which two baffles 7 are rotatably mounted. The two baffles 7 can rotate freely on the central axis 6, thereby realizing the opening and closing of the internal channel of the collector body 1. The mounting block 8 is fixedly mounted on the inner wall of the collector body 1, behind the two baffles 7. One end of the first spring 9 is fixed on the mounting block 8, and the other end is fixedly connected to the baffle 7. This design enables the first spring 9 to provide a reset force when the baffle 7 rotates due to the patient's blowing, so that the baffle 7 can automatically return to its initial position after the patient stops blowing. Two arc-shaped stops 10 are fixedly mounted on the inner wall of the collector body 1, in front of the baffle 7. The design of the arc-shaped stop 10 enables the baffle 7 to fit tightly with the arc-shaped stop 10 when it rotates to the closed position, forming an effective sealing structure. Prevent outside air from entering the collector body 1, and prevent the baffle 7 from rotating in the opposite direction due to the air pressure problem inside the collector body 1; through the coordinated action of the baffle 7, the first spring 9 and the arc-shaped block 10, the blocking component 4 can automatically close the internal channel of the collector body 1 when the patient is not exhaling, effectively preventing outside air from entering and polluting the collection environment; at the same time, when the patient exhales, the baffle 7 can smoothly open the channel to ensure that the exhaled gas can smoothly enter the collecting element 3, thereby avoiding the problem of air leakage; since the blocking component 4 can effectively prevent air leakage, it can ensure the purity and integrity of the gas sample, reduce the detection error caused by sample contamination or dilution, which helps to improve the accuracy and reliability of breath detection and provide a more accurate basis for medical diagnosis.

[0025] The sealing assembly 5 includes a sealing block 11, which is installed on the inner wall of the inlet end of the collecting piece 3. A sealing ball 12 is provided at the inlet of the collecting piece 3, and the sealing ball 12 is located at the sealing block 11. A base 13 is provided inside the collecting piece 3, and a second spring 14 is installed between the sealing ball 12 and the base 13; the sealing assembly 5 also includes four connecting rods 15, and the second spring 14 is fixedly connected to the inner wall of the collecting piece 3 through the four connecting rods 15; a truncated cone-shaped through hole is opened on the sealing block 11, the radius of the lower end of the through hole is larger than the radius of the sealing ball 12, and the radius of the upper end of the through hole is smaller than the radius of the sealing ball 12; the sealing ball 12 is a hollow sphere. The sealing ball 12 is located in the truncated cone-shaped through hole of the sealing block 11. The design of the through hole makes its lower end radius larger than the radius of the sealing ball 12, while the upper end radius is smaller than the radius of the sealing ball 12. This design allows the sealing ball 12 to naturally stay in the lower part of the through hole when not affected by external force, but due to the limitation of the upper end of the through hole, it will not completely break away from the sealing block 11. A second spring 14 is installed between the sealing ball 12 and the base 13. The second spring 14 is fixedly connected to the inner wall of the collecting member 3 through four connecting rods 15. This design enables the sealing ball 12 to move downward when subjected to external force and compress the second spring 14. When the external force disappears, the second spring 14 can provide a reset force to make the sealing ball 12 return to the lower position of the through hole to achieve automatic sealing; the sealing ball 12 is a hollow sphere. This design not only reduces the weight of the sealing ball 12, but also allows it to move more easily when subjected to gas pressure, thereby improving the response speed and sealing effect of the seal.
