Description

Technical Field

[0001] The utility model belongs to the technical field of anesthetic gas purification, in particular to an anesthetic gas purification device. Background Art

[0002] Anesthesia means using drugs or other methods to temporarily make the patient lose all or part of the sensation so as to achieve painless surgical treatment. Anesthesiology is the application of basic theories, clinical knowledge and techniques related to anesthesia to eliminate surgical pain and ensure patient safety. At present, anesthesia methods include puncture anesthesia and inhalation anesthesia. Puncture anesthesia is suitable for local anesthesia, while inhalation anesthesia is suitable for general anesthesia. Inhalation anesthesia is mainly achieved through anesthetic gas. Anesthetic gas is usually a volatile liquid that is inhaled by the patient under the action of the anesthesia machine, thereby achieving an anesthetic effect.

[0003] During the mixing process of anesthetic drugs, they will be exposed to the air for a period of time. It is inevitable that floating dust and bacteria in the air will enter the anesthetic gas. If they are not dealt with in time, the bacteria will directly enter the patient's body through the intubation. Although the existing anesthetic gas purification can purify the anesthetic gas through multiple sets of filters, the purification effect of the anesthetic gas will be greatly reduced after long-term use, and it needs to be replaced. Most of the existing ones fix the multiple sets of filters with bolts. Although the filters can be fixed, it is inconvenient to disassemble them, and it is difficult to maintain a good purification effect. At the same time, the bolts set in the device may also rust, etc., affecting their subsequent normal disassembly. Utility Model Content
