Abstract

一种氧电池校准系统(100)、包括氧电池校准系统(100)的麻醉机以及应用于氧电池校准系统(100)的校准方法，其中，氧电池校准系统(100)包括：呼吸回路(110)，包括吸气支路(111)、呼气支路(112)、吸收罐支路(113)、吸气单向阀(114)、连接管路(116)及呼气单向阀(115)，吸气支路(111)与呼气支路(112)通过连接管路(116)连通；氧电池(120)，连接于吸气支路(111)上，且连接处位于吸气单向阀(114)的后端；以及校准管理单元，校准管理单元控制标定气体进入吸气支路(111)，并经氧电池(120)、连接管路(116)及呼气单向阀(115)流出，校准管理单元根据流经氧电池(120)的标定气体进行氧气浓度校准。在进行氧电池(120)校准时，不需要拔下连接管路(116)，标定气体能够从吸气支路(111)向呼气支路(112)流动，而不会进入吸收罐支路(113)中，实现氧电池(120)自动化校准，保证氧电池(120)工作的可靠性，提升了氧电池(120)校准的便捷性。
