Description

Technical Field

[0001] The utility model relates to the technical field of medical auxiliary equipment, in particular to an exhalation collection bag. Background Art

[0002] The air collection bag is an important tool in the breath test process, used to collect the gas exhaled by the tester. When using the air collection bag, the tester needs to hold the air nozzle of the air collection bag with his mouth and blow air, so that the air collection bag collects and preserves the gas exhaled by the tester. The existing air nozzle design on the market uses injection molding for both the mouth and the inner pad. Since two identical hard plastics are used to connect them, they cannot fit completely together, making it prone to air leakage. The original inner pad design uses a spiral thin sheet. This design itself has the phenomenon of continuous and slow air leakage. In addition, this inner pad is also injection molded with a hard plastic injection molded part. It is connected to the hard mouthpiece, so it cannot fit tightly, resulting in constant air leakage, reducing the gas volume and causing the inability to perform normal testing, affecting the sealing effect of the air collection bag.

[0003] Therefore, there is an urgent need for an exhaled breath collection bag that can effectively improve the sealing effect. Utility Model Content

[0036] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0037] refer to Figure 1-5 The specific embodiment of the utility model provides an exhaled breath collection bag, including an air collection bag (not marked in the figure) and a one-way air nozzle component installed on the air collection bag, and the one-way air nozzle component includes:

[0038] Gas nozzle 1, gas nozzle 1 is sealingly arranged at the inlet of the gas collecting bag;

[0039] The mushroom head silicone nail 4 is clamped in the air nozzle 1, and the air nozzle 1 takes in air in one direction through the mushroom head silicone nail 4.

[0040] The existing air nozzle design on the market uses injection molding for both the mouthpiece and the inner pad. Since two identical hard plastics are used to connect them, they cannot fit completely together, which makes it easy to leak. The original inner pad design uses a spiral sheet. This design itself has two gaps that cannot be sealed. In addition, this inner pad is also injection molded with a hard plastic injection molded part. It is connected to the hard mouthpiece, so it cannot fit tightly, which increases the possibility of air leakage and reduces the amount of gas, resulting in the inability to detect normally. In this application, air is blown into the air collection bag through the air nozzle 1, so that the gas is collected in the air collection bag; the main function of the mushroom head silicone nail 4 is to prevent the gas blown into the air collection bag from being output in the opposite direction through the air nozzle 1. At the same time, a better sealing effect can be achieved through the mushroom head silicone nail 4. On the whole, the present application has a simple structure, effectively collects the oral gas of the tester, and effectively preserves it, which can meet the requirements of a good sealing effect.

[0041] Further optimization plans also include:

[0042] The gas delivery channel 10 is opened in the gas nozzle 1 , and the mushroom head silicone nail 4 is clamped in the gas delivery channel 10 .

[0043] The tester blows out the gas in the oral cavity, which passes through the gas delivery channel 10 and the mushroom-head silicone nail 4 and then enters the gas collection bag.

[0044] Further optimization plans also include:

[0045] The limiting plate 9 is fixedly connected in the gas transmission channel 10, and the mushroom head silicone nail 4 is clamped on the limiting plate 9 and is located at the connection point between the gas transmission channel 10 and the gas collecting bag.

[0046] The main function of the limiting plate 9 is to install the mushroom head silicone nail 4 so that the mushroom head silicone nail 4 is blocked at the connection between the gas transmission channel 10 and the gas collecting bag.

[0047] Further optimization plans also include:

[0048] The vent 2 is provided on the limiting plate 9 , the air collecting bag is connected with the air delivery channel 10 through the vent 2 , and the mushroom head silicone nail 4 is provided corresponding to the vent 2 .

[0049] When no air is introduced, the mushroom head silicone nail 4 is attached to the limit plate 9 and blocks the vent 2. At this time, the air collecting bag is in a relatively closed state. When air is blown into the air nozzle 1, the gas pushes open the mushroom head silicone nail 4, which causes elastic deformation, so that the gas delivery channel 10, the vent 2 and the air collecting bag are connected in sequence. After the blowing stops, the mushroom head silicone nail 4 returns to its original shape.

[0050] Further optimization scheme, mushroom head silicone nail 4 includes:

[0051] The silicone nail cap 5 is clamped on the limiting plate 9 and is fitted on a side of the limiting plate 9 close to the air collecting bag. The silicone nail cap 5 is arranged corresponding to the vent 2.

[0052] The silicone nail cap 5 is in the shape of an umbrella, completely covering the vent 2 in the air nozzle 1, eliminating the gap around it. At the same time, when the air nozzle 1 exhales from top to bottom, the silicone nail cap 5 is easy to open, allowing gas to flow in. When the exhalation stops, the gas automatically flows back to press the entire internal silicone nail cap 5. The soft silicone nail cap 5 is tightly sealed to prevent gas leakage. In this way, even if it is placed for a period of time before testing, there will be no shortage of gas. A gas nozzle cover can also be added to the gas nozzle 1 to protect the hygiene and cleanliness of the gas nozzle 1. It also has a safety that can seal the gas leakage again to form a double sealing function.

[0053] The specific sealing process of mushroom head silicone nail 4 is as follows:

[0054] The silicone nail cap 5 is mainly fitted with the limiting plate 9 on the mushroom head silicone nail 4, and the vent 2 is blocked by the silicone nail cap 5; when no air is introduced, the silicone nail cap 5 fits on the limiting plate 9 according to the elasticity of its own material, and blocks the vent 2; when air is blown into the gas transmission channel 10, the pressure of the gas pushes the silicone nail cap 5 open, that is, it separates from the limiting plate 9, and then the gas enters the air collecting bag; when the blowing stops, the silicone nail cap 5 fits on the limiting plate 9 again according to the elasticity of its own material, and then the sealing is completed.

[0055] Further optimization plans also include:

[0056] The silicone limiting column is fixedly connected to the center of the silicone nail cap 5, and the silicone nail cap 5 is clamped and arranged with the limiting plate 9 through the silicone limiting column.

[0057] The main function of the silicone limit column is to clamp the silicone nail cap 5 on the limit plate 9 to prevent the silicone nail cap 5 from being blown off during the air intake process, and also to prevent the silicone nail cap 5 from shifting in the sealed state to affect the sealing effect.

[0058] To further optimize the solution, the silicone limit column includes:

[0059] A first column 6, which is fixedly connected to the center of the silicone nail cap 5 and passes through the center of the limiting plate 9;

[0060] The first boss 7 is fixedly connected to one end of the first column 6 away from the silicone nail cap 5 , and is clamped on the side of the limiting plate 9 away from the silicone nail cap 5 .

[0061] Since the main material of the silicone limit column is silicone, which is elastic, when installing the mushroom head silicone nail 4, press hard, and the first boss 7 first passes through the center of the limit plate 9, so that the first boss 7 and the silicone nail cap 5 are located on both sides of the limit plate 9 to complete the clamping effect.

[0062] Further optimization plans also include:

[0063] The second boss 11 is arranged on one end of the first column 6 close to the silicone nail cap 5, and is clamped on the side of the limiting plate 9 close to the silicone nail cap 5. The second boss 11 is arranged at the connection between the first column 6 and the silicone nail cap 5, which effectively improves the connection strength between the first column 6 and the silicone nail cap 5, and helps to ensure and stabilize the elasticity of the edge of the silicone nail cap 5.

[0064] After the first boss 7 passes through the center of the limiting plate 9, the second boss 11 contacts the side of the limiting plate 9 close to the rubber nail cap 5. At this time, the first boss 7 and the second boss 11 are respectively located on both sides of the limiting plate 9 to complete the clamping effect; since the silicone nail cap 5 is in an umbrella shape, the silicone nail cap 5 is convex outside and concave inside; when the second boss 11 is clamped on the limiting plate 9, a cavity is formed between the silicone nail cap 5 and the peripheral position of the second boss 11 and the limiting plate 9, so that the edge of the silicone nail cap 5 is tightly attached to the side of the limiting plate 9; on the whole, the second boss 11 contributes to the installation and sealing of the first column 6 on the one hand, and contributes to the sealing between the edge of the silicone nail cap 5 and the limiting plate 9 on the other hand.

[0065] Further optimization plans also include:

[0066] Further optimization plans also include:

[0067] The limiting hole 3 is opened at the center of the limiting plate 9 , and the first column 6 passes through the limiting hole 3 and is adapted to the limiting hole 3 .

[0068] The diameter of the first column 6 is not less than the inner diameter of the limiting hole 3; when the mushroom head silicone nail 4 is clamped on the limiting plate 9, the first column 6 is located in the limiting hole 3, and a certain degree of extrusion and sealing effect is achieved between the first column 6 and the limiting hole 3.

[0069] Further optimization plans also include:

[0070] The second column 8 is fixedly connected to one end of the first boss 7 away from the limiting plate 9 , and the diameter of the second column 8 is smaller than the inner diameter of the limiting hole 3 .

[0071] When installing the mushroom head silicone nail 4, the second column 8 and the first boss 7 pass through the limiting hole 3 in sequence, and finally the first column 6 is located in the limiting hole 3, completing the clamping of the mushroom head silicone nail 4 and the limiting plate 9.

[0072] Further optimization plans also include:

[0073] A cover (not shown in the figure) is snap-fitted onto the gas nozzle 1 .
