Patent number: 11903778Abstract: A medical instrument, medical treatment system and method of assembly. The medical instrument has an instrument body with an RFID tag. An underfloor tag holder receives the RFID tag to fix it in position in such a way that the RFID tag is exposed to the surroundings of the instrument via an opening formed in an instrument body surface, but is set back from the instrument body surface to preferably prevent protrusion beyond the instrument body surface. At least portions of the underfloor tag holder with the RFID tag are enclosed by a separate metal shield having a signal-permeable aperture opening.Type: GrantFiled: August 19, 2020Date of Patent: February 20, 2024Assignee: Aesculap AGInventors: Roland-Alois Hoegerle, Frederick Lenzenhuber, Ralf Pfister
