Description

Technical Field

[0001] The utility model belongs to the field of C13 breath test, in particular to a C13 breath collection bag and a detection instrument. Background Art

[0002] Helicobacter pylori is a bacterium that can grow in the stomach. It can cause gastritis and peptic ulcers and is closely related to gastric cancer. Therefore, if infection with this bacterium can be detected early and the appropriate treatment is taken, the chances of gastrointestinal inflammation, ulcers and other diseases will be reduced.

[0003] The C13 breath test is a commonly used method in medicine to detect Helicobacter pylori.

[0004] The C13 urea breath test is the latest, rapid, painless and radiation-free Helicobacter pylori detection technology. It does not require gastroscopy, but only requires easy exhalation and determination of exhaled breath components to immediately detect whether there is Helicobacter pylori infection. Its main principle is to determine whether Helicobacter pylori infection by testing and comparing the components of exhaled air before and after taking urea carbon 13 capsules. First, through normal breathing, blow the exhaled air into the first air collection bag; then, after taking urea carbon 13 capsules for an appropriate time, blow the exhaled air into the second air collection bag; finally, use a specific detection instrument to detect the exhaled air of the two air collection bags, and determine whether HP is infected by the DOB of Helicobacter pylori.

[0005] During the process of collecting exhaled breath, the lid needs to be closed in time after the bag finishes collecting the exhaled breath. This is especially true for many older people who are slower in their movements. By the time they close the lid after blowing out the air, the previously collected gas has already leaked out, causing inconvenience in use. Utility Model Content

[0006] The purpose of the embodiments of the present utility model is to provide a C13 exhaled air collection bag and a detection instrument, aiming to solve the technical problems raised in the above-mentioned background technology.

[0007] To achieve the above objectives, the utility model provides the following technical solutions.

[0008] In one embodiment of the utility model, a C13 exhalation air collection bag is provided, comprising a bag body, an air inlet on the bag body is provided with an air inlet assembly, and the air inlet assembly comprises:

[0009] The valve core includes a valve seat, a sealing cavity is provided at the bottom of the valve seat, a support is fixedly provided in the sealing cavity, and a ventilation channel is also provided in the valve seat; a sealing plug is also provided in the sealing cavity, and the sealing plug is connected to the support via a connecting spring;

[0010] The blowing nozzle is slidably sleeved on the valve seat up and down, a baffle is fixedly installed on the outer peripheral surface of the blowing nozzle, a bowl-shaped seat is fixedly installed inside the blowing nozzle through the support of a second support rod, and the bowl-shaped seat is connected to the sealing plug through a plug rod.

[0011] Furthermore, the plug rod sliding seal runs through the support, the top end of the plug rod located above the support is fixedly connected to the bowl-shaped seat, and the bottom end of the plug rod located below the support is connected to the sealing plug.

[0012] In another embodiment of the present invention, a detection instrument is provided, the detection instrument comprising:

[0013] The instrument body is provided with an air inlet interface.

[0014] The air inlet interface cooperates with the air inlet assembly of the C13 exhalation air collection bag;

[0015] The air inlet interface includes an interface sleeve, which is installed on the instrument body. A limit rod is fixedly arranged inside the interface sleeve, a limit block is fixedly installed on one end of the limit rod, and a stopper is installed on the other end of the limit rod.

[0016] Furthermore, a supporting channel is provided on the plug rod, a first support rod is fixedly mounted on the support seat, a connecting rod is fixedly connected to the top end of the first support rod, and the connecting rod is adapted to the limit block.

[0038] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0039] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0040] like Figure 1-Figure 4 As shown, in one embodiment of the utility model, a C13 exhalation air collection bag is provided, including a bag body 100, an air inlet on the bag body 100 is provided with an air inlet assembly, the air inlet assembly includes a valve core, the valve core includes a valve seat 200, a sealing cavity 201 is provided at the bottom of the valve seat 200, a support 203 is fixedly provided in the sealing cavity 201, and a ventilation channel 202 is also provided in the valve seat 200, so that external gas can enter the sealing cavity 201 through the ventilation channel 202, and then further enter the bag body 100; a sealing plug 304 is also provided in the sealing cavity 201, The sealing plug 304 is connected to the support 203 via a connecting spring 305. When the sealing plug 304 is pushed out of the sealing cavity 201, the connection state between the sealing cavity 201 and the bag body 100 can be maintained. At this time, it does not affect the gas from entering the bag body 100 through the sealing cavity 201. Accordingly, under normal conditions, the sealing plug 304 can be placed in the sealing cavity 201 through the elastic support connection of the connecting spring 305 and maintain this state, thereby preventing the gas in the bag body 100 from being discharged and external air from entering the bag body 100 through the sealing cavity 201.

[0041] Therefore, in the embodiment of the utility model, by pushing the sealing plug 304 out of the sealing cavity 201 , the valve core can be placed in a conducting state, making it convenient for the patient to blow air into the bag body 100 .

[0042] Correspondingly, the C13 exhalation air collection bag of the utility model embodiment further includes an air blowing nozzle 300, which is slidably sleeved on the valve seat 200 up and down, and a baffle 301 is fixedly installed on the outer peripheral surface of the air blowing nozzle 300, and a bowl-shaped seat 302 is fixedly installed inside the air blowing nozzle 300 through the support of the second support rod 303, and the bowl-shaped seat 302 and the sealing plug 304 are connected by a plug rod 306. Specifically, the plug rod 306 is slidably sealed and runs through the support 203, and the top end of the plug rod 306 located above the support 203 is fixedly connected to the bowl-shaped seat 302, and the bottom end of the plug rod 306 located below the support 203 is fixedly connected to the sealing plug 304. The sealing plug 304 is connected. Based on this, it can be seen that when the patient is blowing, the mouth rests on the baffle 301 to push the blowing nozzle 300 to move relative to the valve seat 200. Under the pushing action of the plug rod 306, the sealing plug 304 can be pushed out from the sealing cavity 201 to put the valve core in a conducting state. At the same time, the patient blows air into the blowing nozzle 300, and the gas passes through the conducting valve core into the bag body 100. When not blowing, the mouth leaves the blowing nozzle 300. Under the elastic support reset action of the connecting spring 305, the sealing plug 304 is reset and rests on the sealing cavity 201 to achieve sealing of the valve core.

[0043] Therefore, the C13 exhalation air collection bag of the utility model does not need to be covered with an additional lid. When the mouth leaves the blowing nozzle 300, the valve core can be automatically closed. Especially for many elderly people, it solves the problem that due to slow movements, the originally collected gas has already leaked when they close the lid after blowing.

[0044] like Figure 6-Figure 9 As shown, in another embodiment of the utility model, a detection instrument is provided, which is used in conjunction with the C13 exhalation air collecting bag of the above-mentioned embodiment. Specifically, the detection instrument includes an instrument body 400, and an air inlet interface 401 is provided on the instrument body 400. The air inlet interface 401 cooperates with the air inlet component in the C13 exhalation air collecting bag of the above-mentioned embodiment. The air inlet interface 401 includes an interface sleeve 4011, which is installed on the instrument body 400. A limiting rod 4012 is fixedly arranged inside the interface sleeve 4011, and a limiting block 4013 is fixedly installed on one side of the end of the limiting rod 4012, and a stop block 4014 is installed on the other side of the end of the limiting rod 4012.

[0045] When the detection instrument of the embodiment of the utility model is in use, the blowing nozzle 300 of the C13 exhalation air collection bag is pushed into the interface sleeve 4011, and then as the bag body 100 continues to be pushed toward the interface sleeve 4011, the blowing nozzle 300 will slide relative to the valve seat 200, and the valve core will be turned on at this time. Although the valve core is turned on at this time, the interface sleeve 4011 has been sleeved on the outside of the blowing nozzle 300, and no air leakage will occur.

[0046] The function of the stopper 4014 is as follows: after the stopper 4014 is pressed onto the bowl-shaped seat 302 , as the bag body 100 continues to be pushed toward the interface sleeve 4011 , the blowing nozzle 300 will slide relative to the valve seat 200 .

[0047] As a preference, Figure 2-Figure 4 As shown, in the embodiment of the utility model, a support channel 3061 is opened on the plug rod 306, a first support rod 204 is fixedly installed on the support 203, a connecting rod 205 is fixedly connected to the top end of the first support rod 204, and the connecting rod 205 is adapted to the limit block 4013.

[0048] Furthermore, the first support rod 204 passes through the supporting channel 3061 .

[0049] Furthermore, the connecting rod 205 has a straight surface structure 2051 and an arc surface structure 2052, and a plurality of limit grooves 2053 are provided at equal intervals along the arc surface structure 2052. When the bag body 100 is pushed toward the interface sleeve 4011, the limit block 4013 will be stuck in the corresponding limit groove 2053. Fig.10 In the state shown, not only the valve core is in the conducting state, but also the C13 exhalation air collecting bag and the detection instrument can be fixed; when the C13 exhalation air collecting bag needs to be removed from the detection instrument, since a straight-face structure 2051 is provided on the connecting rod 205, it is only necessary to rotate the C13 exhalation air collecting bag by a certain angle relative to the detection instrument and disengage the limit block 4013 from the limit groove 2053, so that the C13 exhalation air collecting bag and the detection instrument can be separated smoothly.

[0050] The above solutions are only an illustration of a preferred example, but are not limited thereto. When implementing the present utility model, appropriate replacement and / or modification can be performed according to user needs.

[0051] The number of devices and processing scales described here are used to simplify the description of the utility model. Applications, modifications and variations of the utility model are obvious to those skilled in the art.

[0052] Although the embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the specification and the embodiments. It can be fully applied to various fields suitable for the present invention. For those familiar with the art, additional modifications can be easily realized. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the present invention is not limited to the specific details and the illustrations shown and described here.
