Technical Field

[0001] The utility model belongs to the technical field of anesthesia devices, and in particular relates to a concentration-adjusting anesthesia device for anesthesia department. Background Art

[0002] Anesthesia is a reversible functional inhibition of the central or peripheral nervous system produced by drugs or other methods. The main characteristic of this inhibition is the loss of sensation, especially pain. It is a surgical treatment method that uses drugs or other methods to temporarily make the patient lose sensation as a whole or in part in order to achieve painlessness.

[0003] At present, when adjusting the concentration of anesthesia devices, the mixer needs to manually weigh the drugs or liquids to be mixed, which adds a workload to the preparation. Then, the quantitative drugs or liquids to be mixed are added into the mixing box. When the quantitative drugs are put into the mixed drug box, drugs are easily left on the wall of the tube, which makes it difficult to control the concentration of the mixed anesthetic drugs. At the same time, the existing preparation usually requires medical staff to manually stir the drugs for mixing and preparation, which increases the workload of medical staff and reduces work efficiency.

[0004] Based on this, the utility model designs a concentration-adjustable anesthesia device for anesthesia department to solve the above problems. Utility Model Content
