Abstract

The application belongs to the technical field of anesthetic processing, and is especially an anesthetic processing device for anesthesiology, which comprises an anesthetic body and a lime tank arranged on the anesthetic body, and a reflux pipe is arranged on the lime tank. Through the automatic design of the lime replacement assembly, the discharge of saturated lime and the filling of new lime are completed synchronously under the running state of the anesthetic body, and the design solves the technical problem of interrupting anesthesia caused by replacing lime in the traditional way, and improves the safety and reliability of the anesthesia process. Multiple partitions divide the lime tank into multiple placement areas, each area independently performs carbon dioxide adsorption, and the driving motor can accurately control the rotary discharge according to the actual saturation of each placement area, avoiding the resource waste phenomenon of partial saturation and total waste in the traditional whole replacement. The partition design makes full use of the adsorption capacity of lime, and reduces the cost of medical consumables.
