Technical Field
[0001] This utility model relates to the field of C14 breath test technology, and in particular to a breath test gas collection card that prevents saliva from entering. Background Technology
[0002] The C14 breath test, also known as the Helicobacter pylori breath test, is a method to detect whether a patient is infected with Helicobacter pylori through exhalation. The C14 breath test collection card is a testing tool used for this breath test, and it has the advantages of high accuracy, non-invasiveness, and ease of operation.
[0003] In existing technology, when using a gas collection card to perform the C14 exhalation test, the mouthpiece with a mounting frame is placed close to the gas collection card, and the mounting frame is fitted over the air inlet of the gas collection card. The patient holds the gas collection card and blows through the mouthpiece for three to five minutes until the color card changes from orange to light yellow, at which point the blowing operation is complete. However, this operation has the following problem: many patients tend to blow saliva into the gas collection card during the exhalation test, affecting the accuracy of the values. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as patients easily inhaling saliva into the air collection card, leading to inaccurate test values.
[0005] To achieve the above objectives, this utility model adopts the following technical solution: a breathalyzer test card that prevents saliva from entering, comprising a test card and a mouthpiece. An indicator window is provided on the upper surface of the test card. A protective film is installed on the upper surface of the test card. An installation frame is installed at the air inlet end of the test card. An adjustment structure is provided on the side of the installation frame away from the test card. The adjustment structure includes an adjustment frame, which is fixedly connected to the installation frame. The side of the adjustment frame away from the installation frame is fixedly connected to the mouthpiece. A cover plate is fixedly connected to the upper surface of the adjustment frame. A guide frame is fixedly connected to the side of the mouthpiece near the adjustment frame. A storage box is slidably connected to the bottom inner wall of the adjustment frame. The end of the guide frame away from the mouthpiece is located inside the storage box. A limiting groove is formed on the upper surface of the storage box. A limiting plate is slidably connected to the inner wall of the limiting groove. Two limiting rods are fixedly connected to the lower surface of the limiting plate, located at both ends of the limiting plate. Two fixing blocks are fixedly connected to the inner wall of the adjustment frame, and the fixing blocks are slidably connected to the arc surfaces of the limiting rods.
[0006] The effect achieved by the above-mentioned components is to collect the patient's saliva using a collection box, preventing saliva from entering the test card and improving the accuracy of the experimental values.
[0007] Preferably, a sealing gasket, which is a silicone gasket, is fixedly connected to the upper surface of the adjustment frame.
[0008] The effect achieved by the above components is to increase the airtightness between the cover plate and the adjustment frame through the sealing ring.
[0009] Preferably, the end of the limiting rod away from the limiting plate is arc-shaped.
[0010] The effect achieved by the above components is that the lower end of the limiting rod is arc-shaped, which makes it easier for the limiting rod to slide into the fixing block and improves installation efficiency.
[0011] Preferably, the inner wall of the storage box is fixedly connected with an inner liner, which is a sponge sleeve.
[0012] The effect achieved by the above components is that the inner liner absorbs the saliva flowing into the storage box, and the sponge material of the inner liner has a good absorption effect on saliva.
[0013] In summary, the beneficial effects of this utility model are as follows:
[0014] In this invention, when using a gas collection card for the C14 exhalation test, the mouthpiece with the mounting frame is placed close to the gas collection card, and the mounting frame is fitted over the air inlet of the gas collection card. The patient holds the gas collection card and blows through the mouthpiece for three to five minutes until the color card changes from orange to pale yellow, at which point the blowing operation is complete. However, this operation has the following problem: many patients tend to blow saliva into the gas collection card during the exhalation test, affecting the accuracy of the values. By setting an adjustment structure, the patient's exhaled air and saliva enter the mouthpiece, then the guide frame, and then the storage box. At this point, the storage box blocks the saliva, while the air enters the adjustment frame from the storage box, and then enters the mounting frame and the test card from the adjustment frame. The installation operation of the storage box is as follows: first, operate... The storage box slides into the adjustment frame along the inner wall of the side of the adjustment frame closest to the installation frame. Then, the storage box is moved closer to the guide frame, allowing the guide frame to extend into the storage box a suitable distance. Next, the limiting plate slides into the limiting groove, ensuring that the limiting rod on the limiting plate slides into the fixing block. Finally, the cover is closed. A sealing ring increases the airtightness between the cover and the adjustment frame. The lower end of the limiting rod is arc-shaped, facilitating its sliding into the fixing block and improving installation efficiency. The inner liner absorbs saliva flowing into the storage box; the sponge material of the inner liner provides good absorption of saliva. This achieves the goal of using the storage box to block and collect the saliva inhaled by the patient, while the gas flowing out of the storage box enters the installation frame and the test card through the adjustment frame. This effectively prevents saliva from entering the test card, improving the accuracy of experimental values. Attached Figure Description
