Description

Sodium lime pot and anesthesia machine

Technical Field

The application belongs to the field of medical appliances, and particularly relates to a soda lime tank and an anesthesia machine.

Background

To prevent a patient using an anesthesia machine from inhaling expired carbon dioxide, a canister device is generally provided in the breathing circuit of the anesthesia machine to discharge the expired carbon dioxide into a soda-lime canister for treatment and then into the breathing circuit. For this reason, the material in the soda lime canister needs to be replaced frequently, and the canister body needs to be connected to a cover body provided on the anesthesia machine body after each replacement of the material. Currently, various mechanisms for controlling the connection of the can and the cap have been disclosed in the prior art.

For example, patent document CN104524680a discloses a soda lime tank device, comprising a tank body and a cover body, wherein at least two buckles are arranged on the outer side of the tank body, the cover body comprises an upper cover, a lower shell, lifting rings, cam transmission mechanisms and clamping groove buckles corresponding to the number and distribution positions of the buckles, the lower shell is connected to the lower side of the upper cover, the cam transmission mechanisms are supported on the lower shell, the clamping groove buckles are connected with the lifting rings and can be arranged on the lower shell in a sliding manner up and down, the lifting rings are supported on the cam transmission mechanisms, the buckles are clamped in the clamping groove buckles, the cam transmission mechanisms drive the connecting rings to move upwards, and the tank body is attached to the cover body by pushing the buckles through the clamping groove buckles.

The above patent discloses a structure using cams to control the lifting and lowering, and more simply using a screw rotation method, but these methods are all manually controlled. In order to ensure air tightness, a sealing ring is generally arranged in a cover body of a sodium lime tank of the existing anesthesia machine, and the tank body is lifted to a position where the cover body is located by using a relatively complex mechanical structure, so that the tank body is required to be rotated or a handle for opening is required to be pulled by using relatively large force when the cover body is manually opened. For this reason, there is a need to design a soda lime tank that does not require manual effort to open in order to solve this technical problem.
