[0031] This specification may use the phrases "in one embodiment," "in another embodiment," "in a further embodiment," or "in other embodiments," all of which may refer to one or more of the same or different embodiments according to the present disclosure.

[0032] Below, the embodiments of the utility model are described in detail with reference to the accompanying drawings.

[0033] like Figures 1 to 4 As shown, an embodiment of the utility model provides a carbon dioxide absorption tank, comprising: a tank body 10 with an open top, wherein a storage space is formed inside the tank body 10, and an air inlet 11 is formed through the open top to receive the gas to be processed from the anesthesia machine through the air inlet 11; an air outlet pipe 15 is arranged inside the tank body 10 and extends through the open top to discharge the gas in the storage space through the air outlet pipe. The air outlet pipe 15 includes a first section of pipe 151 located inside the tank body 10, wherein the first section of pipe 151 extends toward the bottom in contact with the first side wall, and a gap is left between the first section of pipe 151 and the bottom to form a gas circulation channel. In some practical applications, the material of the air outlet pipe 15 can be the same as that of the tank body 10, for example, both are made of hard materials such as metal, so that the air outlet pipe 15 can be welded to the side wall for fixation, or can be formed of a plastic hard pipe to avoid deformation when squeezed and affect the circulation of gas. The size of the air outlet pipe 15 is adapted to the size of the gas inlet of the anesthesia machine. The air outlet pipe 15 can be set to a corresponding bending shape according to the requirements of the connection position, so that the position of the air outlet 14 can be connected to the gas inlet of the anesthesia machine. At the same time, the first section of the pipe 151 located inside the tank body 10 can fit with the first side wall. The second side wall of the tank body 10 is provided with an opening 18, and a cover assembly 20 that is sealed and adapted to the opening 18 is provided. In some specific applications, the positions of the first side wall and the second side wall can be selected according to actual conditions, and the second side wall and the first side wall can be in relative positions to each other.

[0034] In some practical applications, a connection portion may be provided on the inner wall of the opening, for example, an internal thread may be constructed, and the tank body 10 can be fixed by threaded connection with an external thread constructed on one end of the gas inlet and outlet of the anesthesia machine through the opening. The tank body 10 can form an air inlet 11 through the opening, and after being connected to the anesthesia machine, the gas including carbon dioxide can be received into the storage space from the gas outlet provided on one end of the gas inlet and outlet of the anesthesia machine through the air inlet 11 to absorb the carbon dioxide. The shape and volume of the tank body 10 can be set according to actual needs, for example, set to a cylinder, etc. After the tank body 10 is connected to the anesthesia machine through the opening, a storage space connected to the gas channel of the anesthesia machine is formed inside, and the storage space can be used to hold a soft bag 30 filled with a carbon dioxide absorbent to absorb the carbon dioxide in the gas and achieve gas treatment. One end of the gas outlet pipe 15 is arranged inside the tank body 10, and the other end is extended out to be open to be connected to the gas inlet arranged on one end of the gas inlet and outlet of the anesthesia machine, so that when the treated gas in the tank body 10 is discharged through the gas outlet pipe 15, it can enter the gas circulation passage of the anesthesia machine through the gas inlet of the anesthesia machine.

[0035] An opening 18 and a cover assembly 20 that is sealed and adapted to the opening 18 are provided on the side wall of the tank body 10. The cover assembly 20 cooperates with the opening 18 to open the carbon dioxide absorbent in the storage space through the opening 18, or when the cover assembly 20 cooperates with the opening 18 to close, the sealing performance of the storage space is guaranteed.

[0036] Further, the cover assembly 20 includes a cover body 21, a buckle 22 provided on the cover body 21, a boss 23 adapted to the buckle 22, and a frame 24 provided between the cover body 21 and the tank body 10. The shape of the frame 24 can match the opening 18, or can be set to be mismatched according to actual conditions. For example, when the opening 18 is set to be circular, the frame 24 can be set to a matching circle or a mismatched rectangle, as long as it can cover the size of the opening 18. The shapes of the opening 18 and the frame 24 are not limited in this embodiment. In this embodiment, the area enclosed by the frame 24 is larger than the area of ​​the opening 18, and one side matches the arc of the tank body 10, and is sealed on the tank body 10, located around the opening 18, and the other side forms a plane, which cooperates with the cover body 21 to form a seal. In some specific applications, the frame 24 includes two opposite sides, one side of which is rotatably connected to the cover body 21, and the other side of the opposite side is provided with a boss 23. The shape and size of the cover body 21 match the frame 24. The cover body 21 has two sides corresponding to the two sides of the frame 24, one of which is rotatably connected to the frame 24, and the other side opposite to it is provided with the buckle 22. The shape and size of the buckle 22 match the shape and size of the boss 23, and they can be engaged with each other. When one side of the cover body 21 rotates relative to the frame 24, the other side opposite to it can abut against the corresponding side of the frame 24. At this time, the buckle 22 can be engaged with the boss 23, so that the cover body 21 is covered in the frame 24 and the opening 18 is closed; or it can be away from the corresponding side of the frame 24, so that the user can replace the carbon dioxide absorbent through the opening 18.

[0037] In some embodiments, a groove (not shown) is provided on the frame 24, and the groove is used to place a sealing ring, so as to ensure the sealing performance of the accommodation space through the elasticity of the sealing ring. In this way, when the cover body 21 is covered on the frame 24, the two sides of the sealing ring are respectively in contact with the cover body and the frame 24 to seal between the cover body and the frame 24 to prevent the gas in the accommodation space from leaking out.

[0038] In some embodiments, the gas outlet pipe further includes a second section of pipe 152, which is L-shaped and includes a first side 1521 and a second side 1522; the first side 1521 is vertically connected to the first section of pipe 151. In some practical applications, when the open portion of the tank body 10 is formed with a connection portion (e.g., an internal thread), the first side 1521 can be adjacent to the lower edge of the connection portion, for example, adjacent to the last circle of thread of the internal thread toward the bottom of the tank body 10, so as to avoid interference with the connection between the carbon dioxide absorption tank and the anesthesia machine, while leaving the maximum space for the soft bag to be accommodated. The second side 1522 extends from the middle of the open portion, and the extended port forms an outlet 14 connected to the accommodation space. Here, the specific extended position of the second side 1522 can be set in combination with the gas inlet of the anesthesia machine, so that after the carbon dioxide absorption tank is connected to the anesthesia machine through the connection portion of the open portion, the outlet 14 can be connected to the gas inlet of the anesthesia machine to form a gas channel.

[0039] In some embodiments, the cross-sectional area of ​​the end where the port is located gradually decreases in the direction toward the port, so that the gas outlet pipe 15 can be conveniently extended into the gas inlet of the anesthesia machine through a smaller pipe opening, and the gas inlet is clamped by the gradually thickening pipe to form a sealed connection.

[0040] In some embodiments, in order to fix the outlet pipe 15, the carbon dioxide absorption tank of the embodiment of the present application further includes a bracket 17, the shape of the bracket 17 can be roughly set to a rod shape, and the two ends of the bracket 17 are respectively connected to the side wall of the tank body 10 and the first edge 1521 to fix the outlet pipe 15. In some practical applications, 2 or 4 brackets 17 can be symmetrically arranged around the first edge 1521 to make the outlet pipe 15 more stable.

[0041] In some embodiments, in order to facilitate the soft bag 30 containing the carbon dioxide absorbent to absorb the gas, a partition 19 is provided in the horizontal direction inside the tank body 10, and the partition 19 is used to separate the containing space into two upper and lower sub-containing chambers, and the gas can flow between the two sub-containing chambers. The partition 19 is provided on the inner wall of the tank body 10, and its shape can be set according to actual needs, for example, it is set to be circular or rectangular, etc. In some practical applications, the shape of the partition 19 can be different from the cross-sectional shape of the tank body 10, so that a gap flows out between the partition 19 and the inner wall of the tank body 10, so that the gas can flow between the two sub-containing chambers; or, the shape of the partition 19 can also be the same as the cross-sectional shape of the tank body 10, and the partition 19 and the inner wall of the tank body 10 are not sealed, or a through hole is provided on the partition 19, so that the gas can flow between the two sub-containing chambers.

[0042] In some embodiments, the outlet pipe 15 extends deep into the bottom along the inner wall of the tank body 10, and its inlet end 1511 penetrates the partition 19, extends into the sub-accommodation cavity below, close to the bottom of the accommodation space, and forms a certain gap with the bottom of the accommodation space. The size of the gap can be determined according to actual conditions, so that after carbon dioxide enters the tank body 10, it diffuses in the accommodation space to fully react with the carbon dioxide absorbent, and then enters the outlet pipe 15 through the inlet end 1511, thereby discharging the treated gas to improve the absorption effect of carbon dioxide inside the tank body 10. In some practical applications, the cross-sectional shape of the outlet pipe 15 can be set according to actual conditions, for example, set to a circular or oblate shape.

[0043] like Figure 5 As shown, this embodiment also provides a soft bag 30, which is applied to the carbon dioxide absorption tank described in any of the above embodiments, and can be placed in the containing space through the opening 18. The soft bag 30 includes a bag body 31, and the bag body 31 forms an internal space for containing carbon dioxide absorbent, which includes a non-woven fabric layer arranged on the outside and a sponge layer facing the internal space to prevent the carbon dioxide absorbent from leaking from the bag body 31. In some specific applications, the shape and size of the soft bag 30 can be set according to the opening 18 and the shape and size of the tank body 10 of the carbon dioxide absorption tank in actual application, for example, it can be roughly set to a cylindrical shape, or a rectangular shape, etc. In some practical applications, the soft bag 30 can be opened at the top, and the manufacturer can fill the carbon dioxide absorbent through the opening at the top and then seal it for subsequent use.

[0044] In some embodiments, the soft bag 30 further includes a handle 32, which is generally in the shape of a strip, and its specific shape and size can be set by a technician based on experience, and both ends of the handle 32 are arranged on the top of the bag body 31. In this way, when the user replaces the carbon dioxide absorbent in the carbon dioxide absorber, the soft bag 30 can be conveniently taken out or put in through the handle 32.
