when unabsorbed anesthetic in the gas exhausted from the anesthetic exhaust gas filtering unit 110 passes through the scale unit 120, the scale unit 120 may be corroded, and the scale unit 120 may be easily broken down after long-term use;
the joint between the anesthetic waste gas filtering unit 110 and the anesthetic waste gas absorption unit 130 is not tight enough, and there is a risk of waste gas leakage.
The inventors of the present application have made improvements to the structure of an anesthetic gas treatment apparatus to solve the above-described technical problems.

The screw connection of the boss 2111 and the groove 2231 can improve the air tightness and prevent the leakage of anesthetic waste gas.
In some embodiments, a seal (not shown) is disposed between the first connection portion 211 and the second connection portion 223. For example, the sealing member includes a sealing gasket, such as a rubber ring, to increase the tightness of the fit between the filtering device 210 and the negative pressure device 220, so as to prevent the anesthetic waste gas from leaking.
In some embodiments, referring to fig. 4 and 5, the filtering device 210 includes a first casing 10, a containing cavity 11 for containing the adsorbing material 80 is formed inside the first casing 10, a first end 12 of the first casing 10 is provided with a first air inlet 121, a second end 13 of the first casing 10 is provided with a first air outlet 131, and the second end 13 is connected to a first side 221 of the negative pressure device 220. The negative pressure device 220 is used for providing negative pressure at the first air outlet 131 of the filtering device 210, so that the anesthetic gas flows into the filtering device 210 from the first air inlet 121, and is output to the negative pressure device 220 from the first air outlet 131, and is discharged by the negative pressure device 220, for example, can be discharged to an exhaust gas treatment center.
Illustratively, the filtering device 210 is provided with a blocking member 50 in the accommodating chamber 11 near the first air outlet 131 and the first air outlet 131, and the blocking member 50 is made of foam or sponge material, for example, and can prevent the absorbing material from entering the gas transmission pipeline.
For example, the first air inlet 121 is used to connect a pipeline for outputting anesthetic waste gas, such as the bellows 60, to collect anesthetic waste gas.
For example, the second air inlet 21 includes one or more air inlets, which may be a raw air inlet or an annular air inlet, but is not limited thereto.
In some embodiments, referring to fig. 6, the negative pressure device 220 includes a second housing 20, and a fan and a motor (not shown), wherein the second housing 20 is provided with a second air inlet 21 and a second air outlet 22, and the second air inlet 21 is located on the first side 221; the fan blades are located in the second casing 20, and the motor is used for driving the fan blades to rotate so as to discharge the gas in the second casing 20 through the second gas outlet 22 and form negative pressure at the second gas inlet 21.
Illustratively, the second air outlet 22 is located at the outer periphery of the second housing 20. The second air outlet 22 is not arranged on the side close to the weighing device 230, so that the anesthesia waste gas of the second air outlet 22 can be prevented from corroding the weighing device 230.

Illustratively, the first housing 10 is integrally formed with the second housing 20. For example, the filter device 210 and the negative pressure device 220 are integrally formed and only have the shape of a can in appearance. The air tightness of the filtering device 210 and the negative pressure device 220 can be improved, and the leakage of the anesthetic waste gas can be prevented.
For example, referring to fig. 8, the first casing 10 of the filtering device 210 includes an accommodating portion 14 and a cover 15, the accommodating portion 14 is provided with an opening 141, and the cover 15 is detachably connected to the accommodating portion 14 or the cover 15 can rotate relative to the opening 141 of the accommodating portion 14, so that the cover 15 closes the opening 141 or opens the opening 141. It is convenient for the user to replace the adsorbing material 80 in the accommodating part 14 through the opening 141, so that the use cost is reduced, for example, the first casing 10 of the filter device 210 can be used many times. The waste caused by the fact that the interface of the purchased filter device 210 is not matched with the interface of the negative pressure device 220 can be avoided.
Illustratively, as shown in fig. 8, the cover 15 is located at the second end 13 of the first housing 10. When the cover 15 is removed, i.e., separated from the housing 14, the adsorbent 80 can be replaced through the opening 141 in the housing 14.
