When the gas is discharged into the adsorption bin A201 from the air inlet 101, it is convenient for the gas to enter the entire chamber evenly and quickly from the semicircular opening and the air permeable plate, and fully contact with the medium in the adsorption bin A201, thereby reducing the dead space volume.

[0045] Embodiment three:

[0046] See also Figure 1 , Figure 3 A partition plate 204 is provided at the bottom of the adsorption bin A201, and a hollow structure is provided on the partition plate 204. The height of the partition plate 204 is higher than the height of the bottom of the ventilation duct 202. The arc seat 301 is pressed against the partition plate 204 to form a closed space.

At this time, the adsorption bin A201 is in a closed state, and the anesthetic gas during the operation will not be wasted, saving resources. At this time, the ventilation duct 202 is connected with the air inlet 101, and other waste gas enters the ventilation duct 202 from the air inlet 101 and then enters the cavity 305 of the base 3 from the arc groove, and then is discharged into the adsorption bin B4 from the five-hole plate 302, and finally is discharged from the air outlet 102. Through this design, the adsorption bin A201 and the ventilation duct 202 will not affect each other during waste gas adsorption, will not damage the original respiratory tract, and avoid cross infection.

[0050] Embodiment 4:

[0051] See also Figure 5-6 The dual channel includes a ventilation duct 202 and an adsorption bin A201.

At the same time, when there is no need to adsorb anesthetic waste gas, the ventilation pipe 202 and the adsorption chamber A201 are set to gas channels with unequal inner diameters. When the ventilation pipe 202 is rotated to a position where it is not connected to the air inlet 101, at the same time, the adsorption chamber A is also not connected to the air inlet 101. At this time, the adsorption chamber B4 is in a completely closed state, and the anesthetic gas during the operation will not be wasted, thus saving resources.
