Publication number: 20050097191Abstract: A medical equipment control system consists mainly of a plurality of centralized controllers each of which controls on a centralized basis a plurality of pieces of medical equipment installed in an operating room, and a mobile device capable of communicating with the plurality of centralized controllers. The mobile device is used to determine or record control data based on which the plurality of pieces of medical equipment is controlled. The recorded control data is transmitted to and recorded in the centralized controller in an operating room concerned. Thus, a medical equipment control system capable of controlling medical equipment at low cost on a centralized basis is realized.Type: ApplicationFiled: October 14, 2004Publication date: May 5, 2005Applicant: OLYMPUS CORPORATIONInventors: Masahide Yamaki, Kenji Noda, Akinobu Uchikubo, Takashi Ozaki, Hiroyuki Mino, Shigeo Nagayama, Daisuke Sano, Masaya Fujita, Nobuyuki Furukawa, Sumihito Kontshi
