The device 6 that can be connected to the medical device 5 confirms the figure of merit 22 based on the shape deviation between the time measurement signals 11 and 13 after normalization, and the time measurement signals 11 and 12 are sent to the medical device 5. Received from integrated sensors 56, 57. A system comprising the apparatus and a method for confirming the figure of merit are further presented.医療機器５に接続可能な装置６が、正規化後の時間的測定信号１１、１３の間の形状偏差に基づいて性能指数２２を確認し、時間的測定信号１１、１２は、医療機器５に一体化されたセンサ５６、５７から受信される。前記装置を有するシステム及び前記性能指数を確認する方法が、更に提示される。
