This application relates to the field of medical device technology, and more particularly to a respiratory gas absorption filter, comprising a housing, an air inlet pipe and an air outlet pipe disposed on the housing, a guide vane disposed on the air inlet pipe, a first thin cotton and a first thick cotton disposed at one end of the interior of the housing, and a second thick cotton, a plastic sheet, corrugated paper and a second thin cotton disposed at the other end of the interior of the housing, wherein the plastic sheet is uniformly provided with at least one vent hole, and an adsorption medium is disposed inside the housing. Therefore, a respiratory gas absorption filter can solve the technical problems of existing adsorption media having fine particles that are easily squeezed out from the gap between the adsorption cotton and the canister under the impact of high-frequency airflow or equipment vibration of anesthesia machines, and the simple pore structure of the adsorption cotton material used in traditional adsorption canisters, which causes condensate to accumulate inside the canister under long-term gas exposure.

The embodiment of the present application provides an interlocking module, an evaporator and an anesthesia machine. The interlocking module comprises a mounting seat, a knob, an ejection assembly, a connecting rod assembly and an ejection piece. The ejection piece is in sliding connection with the mounting seat. The connecting rod assembly is arranged between the knob and the ejection assembly. The connecting rod assembly comprises a follower and a linkage. The follower is connected with the knob. When the knob rotates, the follower can drive the linkage to move. The linkage further drives the ejection piece to move outwardly from the mounting seat, so that the ejection piece moves from an initial position to an interlocking position. The ejection pieces of two evaporators are arranged at intervals. When an operator rotates one of the evaporators, the corresponding ejection piece extends and abuts against the ejection piece of the other evaporator, thereby limiting the movement of the ejection piece. Thus, the rotation of the knob of the other evaporator is further limited, and the simultaneous use of two anesthetics is avoided.

This utility model provides an anesthesia reservoir for an anesthesia machine, relating to the field of anesthesia machine technology. It includes a reservoir with a connecting tube at one end, a connecting ring in the middle, hinge shafts on both sides of the inner wall of the connecting ring, a limiting arc block in the middle of the hinge shafts, a rotating ring connected to the middle of the connecting ring, and a transmission component on the inner wall of the limiting arc block. The transmission component is driven by the rotating ring and connected to the limiting arc block. This invention solves the problem that the pressure applied to the reservoir in anesthesia machines cannot be precisely controlled, making it difficult to accurately control the amount of gas delivered according to the patient's needs. By deflecting the limiting arc block in this device, the degree of compression of the reservoir is limited, thereby controlling the amount of gas expelled by the compression and preventing excessive gas expulsion due to uncontrolled pressure, which would hinder the adjustment of the required respiratory rate.
