Description

Technical Field

[0001] The utility model relates to the technical field of air collection bags, in particular to an air collection bag for a Helicobacter pylori breath test. Background Art

[0002] The breath test bag is a widely used device in the medical field, especially in the Helicobacter pylori breath test. It is mainly used to collect the gas exhaled by the patient so that the doctor can analyze the gas composition and determine whether the patient has specific health problems.

[0003] The breath test air collection bag usually includes a bag body with an inner cavity and a mouthpiece arranged on the bag body, such as the Chinese utility model patent disclosed by publication number CN212165811U: Breath test air collection bag. This application enables the patient to hold the second air inlet mouthpiece in his mouth to blow air, and the gas enters the bag body from the second air inlet mouthpiece and the first air inlet mouthpiece in turn. After the gas is collected, the second air inlet mouthpiece can be disassembled and discarded or centrally disinfected. This avoids the droplets, saliva, etc. in the gas blown by the user from contaminating the air collection bag and causing cross infection of medical staff. However, after the patient blows gas into the bag, the patient's mouth is separated from the air collection bag, which will cause some gas in the air collection bag to escape. At the same time, in most cases, the operation of the air collection bag is hand-held, so it will cause the hand strength to be poorly controlled and accelerate the escape of gas in the air collection bag, thereby affecting the collection of gas. In addition, both the application and the existing air collection bag have a short bag mouth length, and when the gas is subsequently transferred to the detection instrument, the gas cannot be accurately delivered to the detection equipment. Utility Model Content

[0004] The utility model aims to provide a Helicobacter pylori breath test air collection bag, which can effectively solve the problems in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] In the utility model, a closed bag is arranged in the air collecting bag body, so that when blowing, the gas can be transported unidirectionally into the air collecting bag body to prevent the gas in the air collecting bag body from escaping. In addition, with the help of the sealing cover and the setting of the top pipe, the air guide pipe and the sealing plug, the bag mouth pipe can be sealed. At the same time, when exhausting, the other gases in the air collecting bag body can be accurately transported to the detection equipment with the help of the top pipe and the extended air guide pipe.

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] like Figure 1-Figure 4 As shown, the utility model provides an air collection bag for a Helicobacter pylori breath test, comprising an air collection bag body 1, a bag mouth tube 2 is fixedly installed on one side of the air collection bag body 1, an air blowing tube 3 is fixedly installed on one side of the bag mouth tube 2, a sealing cover 5 is movably connected to the outer side of the air blowing tube 3, a slot 6 is provided in the sealing cover 5, a top tube 8 is fixedly connected to one side of the slot 6, and an air guide tube 9 is movably installed in the top tube 8.

[0023] A closed bag 10 is fixedly connected inside the bag mouth tube 2. The closed bag 10 has a trumpet-shaped structure, and the bag mouth on one side of the closed bag 10 closes automatically. With the arrangement of the closed bag 10, the gas exhaled by the user can enter the gas collecting bag body 1 during blowing and prevent the gas in the gas collecting bag body 1 from being discharged, thereby improving the gas collection efficiency. The longitudinal cross-section of the blowing tube 3 has a stepped structure, and a spiral pattern 4 is arranged on the outer side of the blowing tube 3 near the bag mouth tube 2.

[0024] like Figure 3-Figure 4 As shown, a screw groove 7 is provided on the inner side of the slot 6, and a plurality of air holes 11 are provided at one end of the top pipe 8. The sealing cover 5 is installed on the blowing pipe 3 through the slot 6, and the screw groove 7 is threadedly connected to the spiral pattern 4. With the arrangement of the top pipe 8, the sealing cover 5 can seal the bag mouth tube 2 and then open the closed bag 10, which is convenient for subsequent exhaust operation. A sealing ring 12 is fixedly installed on one side of the air guide tube 9, and a plurality of breakaway pieces 14 are fixedly connected on the other side of the air guide tube 9, and a sealing plug 13 is movably connected on the side of the breakaway piece 14 away from the air guide tube 9. The air guide tube 9 is installed in the top pipe 8 through the sealing ring 12, and the sealing plug 13 is installed in the notch on one side of the air guide tube 9. Through the arrangement of the air guide tube 9 and the sealing plug 13, the sealing plug 13 can be opened when the exhaust operation is performed, and the air guide tube 9 can be pulled out at the same time, so as to facilitate the gas in the air collection bag body 1 to be introduced into the designated equipment.

[0025] It should be noted that the utility model is an air collection bag for a Helicobacter pylori breath test. When collecting exhaled gas through the air collection bag body 1, the patient can bite the air blowing tube 3 with his mouth and blow air into the air collection bag body 1 through the air blowing tube 3, so that the gas blown out by the patient will push open the two fitting parts on one side of the closed bag 10, and then the gas will enter the air collection bag body 1 for collection. When the patient stops blowing, the two parts on one side of the closed bag 10 are adsorbed and fitted to each other, which can prevent the gas in the air collection bag body 1 from being discharged due to the pressure of the air collection bag body 1. After the gas in the air collection bag body 1 is collected, the top tube 8 can be gradually inserted into the air collection bag body 1 through the sealing cover 5 through the air blowing tube 3. The air collecting bag body 1 is in the air collecting bag body 1, and one side of the top pipe 8 pushes open one side of the closed bag 10. At the same time, the sealing cover 5 is threadedly connected to the blowing pipe 3 by means of the slot 6 and the screw groove 7. When it is necessary to discharge the gas in the air collecting bag body 1, the sealing plug 13 can be pulled outward, so that the sealing plug 13 drives the air guide pipe 9 to move in the top pipe 8 through the multiple breaking pieces 14, so that the sealing ring 12 on one side of the air guide pipe 9 and the notch on one side of the top pipe 8 are mutually restrained and limited, and then the sealing plug 13 is twisted to separate the sealing plug 13 from the multiple breaking pieces 14. At this time, pressure can be applied to the air collecting bag body 1, so that the gas in the air collecting bag body 1 is discharged through the top pipe 8 and the air guide pipe 9.
