Description

Technical Field

[0001] The utility model relates to a carbon dioxide absorber device, in particular to a carbon dioxide absorber device with an artificial nose filter, belonging to the technical field of medical equipment. Background Art

[0002] In the prior art, a carbon dioxide absorber is disclosed in the utility model with application number 202121728380.2. In order to solve the problem that carbon dioxide cannot be completely absorbed by the carbon dioxide absorbent, a spherical tube is added to the tank body. When the gas enters the tank body from the air inlet, it will directly enter the spherical tube. The flow rate of the gas in the spherical tube is slowed down, which increases the reaction time of the gas and the carbon dioxide absorbent. In addition, the distance between the other end of the spherical tube and the top of the tank body is small, and the gas discharge speed is also slow, which also increases the time the gas stays in the spherical tube. After the gas flows out of the spherical tube, it needs to flow from the top of the tank body to the bottom of the tank body, and then go out from the exhaust port at the bottom of the tank body. While slowing down the gas flow rate, the present invention also lengthens the distance the gas flows in the tank body, so that the carbon dioxide absorbent in the tank body can fully absorb the carbon dioxide in the gas.

[0003] Similar to the above application, there are still some shortcomings:

[0004] During use, there is a certain temperature difference between the gas absorbed by the patient and his own temperature, which will cause certain stimulation, affecting the comfort of use. At the same time, it cannot reduce the hidden dangers caused by cross contamination, and the functionality is low;

[0005] For this reason, a carbon dioxide absorber device with an artificial nose filter is designed to optimize the above-mentioned problems. Utility Model Content

By arranging an artificial nose at the air outlet of the shell, not only can the heat and humidity of the patient's exhaled gas be retained, but also the bacteria and viruses in the inhaled gas can be isolated, effectively avoiding cross infection, and improving the safety and functionality of the device. By arranging a honeycomb partition bar and a first sponge pad at the inner bottom of the shell, the internal space of the shell can be divided, the top of the first sponge pad forms an absorption area and the bottom forms a water vapor collection area, which can avoid the lime from being soaked and ensure the absorption effect.

[0023] In order to make the technical solution of the utility model more clear and specific to those skilled in the art, the utility model is further described in detail below in conjunction with embodiments and drawings, but the implementation methods of the utility model are not limited thereto.

[0024] like Figure 1-Figure 3 As shown, the present embodiment provides a carbon dioxide absorber device with an artificial nose filter, comprising a shell 1, an air inlet 2 is provided at the top of one side of the shell 1, an air outlet 3 is provided at a side of the shell 1 away from the air inlet 2 and at a position opposite to the air inlet 2, an artificial nose 4 is installed on the air outlet 3, a honeycomb partition 5 is provided at the inner bottom of the shell 1, a gap is left between the lower part of the honeycomb partition 5 and the inner bottom of the shell 1, a first sponge pad 6 is provided at the top of the honeycomb partition 5, and the space between the top of the first sponge pad 6 and the inside of the shell 1 is filled with lime 7, and a drainage mechanism is provided at the inner top of the shell 1.

[0025] Overall working principle: During use, the patient wears a breathing mask, and the gas exhaled by the patient first enters the interior of the shell 1 through the air inlet 2, and the carbon dioxide gas is absorbed by the lime 7. When the carbon dioxide enters, the drainage mechanism is used to extend the residence time of the gas inside the shell 1 to ensure the absorption effect of carbon dioxide. The gas is then discharged from the artificial nose 4, and the artificial nose 4 is used to retain the heat and humidity of the exhaled gas, while isolating the bacteria and viruses in the inhaled gas.

[0026] In this embodiment, the drainage mechanism is a first partition plate 8, which is vertically installed between the inner top of the honeycomb partition bar 5 and the inner top of the shell 1, and the distance between the first partition plate 8 and the air inlet 2 is smaller than the distance between the first partition plate 8 and the air outlet 3.

[0027] Local working principle: After the carbon dioxide gas enters the interior of the shell 1, the gas will flow downward through the honeycomb partition 5 to the bottom of the shell 1, then enter the other side of the first partition 8, and then be discharged from the outlet 3, thereby prolonging the residence time of the carbon dioxide inside the shell 1.

[0028] In this embodiment, a second sponge pad 9 is provided between the side of the first partition plate 8 close to the air inlet 2 and the inner side of the shell 1. The second sponge pad 9 is located below the air inlet 2. A third sponge pad 10 is provided inside the shell 1 close to the air outlet 3.

[0029] Local working principle: When the exhaled gas flows inside the shell 1, the first sponge pad 6, the second sponge pad 9 and the third sponge pad 10 can collect water vapor to prevent the water vapor from wetting the limestone 7.

[0030] In this embodiment, the drainage mechanism includes an inverted L-shaped duct 11 and a spiral blade 12. The horizontal tube end of the inverted L-shaped duct 11 is connected to the air inlet 2. The vertical tube of the inverted L-shaped duct 11 is located in the middle position of the shell 1, and the bottom end of the inverted L-shaped duct 11 extends to below the first partition 8. A spiral blade 12 is provided between the outer side of the vertical tube on the inverted L-shaped duct 11 and the inner wall of the shell 1.

[0031] Local working principle: the exhaled carbon dioxide gas directly enters the inner bottom of the shell 1 through the inverted L-shaped conduit 11, and then flows upward to contact the limestone 7. Due to the guiding effect of the spiral blades 12, the residence time of the gas inside the shell 1 is prolonged.

[0032] In this embodiment, the inner diameter of the inverted L-shaped conduit 11 is the same as the inner diameter of the air inlet 2, and the inner diameters of the tube bodies of the inverted L-shaped conduit 11 are the same.

[0033] Partial working principle: Since the inner diameter of the inverted L-shaped conduit 11 is the same as the inner diameter of the air inlet 2, the smooth flow of the exhaled gas can be ensured.

[0034] In this embodiment, the drainage mechanism includes an air duct 13, a second partition plate 14 and a fourth sponge pad 15. The top end of the air duct 13 is connected to the air outlet 3, and the bottom end of the air outlet 3 is installed on the top of the honeycomb partition bar 5. The second partition plate 14 is vertically installed between the top of the air duct 13 and the inner top of the shell 1, and the fourth sponge pad 15 is horizontally provided between the side of the air duct 13 and the inner side of the shell 1.

[0035] Local working principle: After the exhaled gas enters the interior of the shell 1, due to the obstruction of the second partition 14, the gas first flows downward through the fourth sponge pad 15 to absorb water vapor, and then uses the lime 7 for thorough contact to absorb carbon dioxide gas. Finally, the exhaled gas enters the bottom of the shell 1 and is discharged upward along the air duct 13.

[0036] In this embodiment, the air guide tube 13 is in a corrugated shape, and the diameter of the bottom end of the air guide tube 13 is greater than the diameter of the top end.

[0037] Partial working principle: The corrugated air guide tube 13 also has a certain flow guiding effect, which prolongs the residence time of the gas.

[0038] The above is only a further embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the scope disclosed by the present invention according to the technical solution and concept of the present invention, which fall within the protection scope of the present invention.
