PROBLEM TO BE SOLVED: To provide a medical instrument, a medical system, and a communication state check method that are capable of easily grasping a radio connection state in performing radio communication between medical instruments.SOLUTION: A communication unit 110 performs radio communication with a medical instrument 20. A control unit 130 detects a state of the communication unit 110s radio communication with the medical instrument 20. A reporting unit 160 reports the state of radio communication detected by the control unit 130 by using at least one of a light-emission notification method, a vibration notification method, and an acoustic sense notification method.SELECTED DRAWING: Figure 2COPYRIGHT: (C)2017,JPO&INPIT【課題】医療機器間で無線通信を行う際に無線接続状態を容易に把握することが出来る医療機器、医療システム、及び通信状態確認方法を提供すること。【解決手段】通信部110は、医療機器20との無線通信を行う。制御部130は、通信部110による医療機器20との無線通信状態を検出する。報知部160は、制御部130が検出した無線通信状態を発光報知、震動報知、及び聴覚報知の少なくとも一つの方法により報知する。【選択図】図2
