Raimo Nikkanen started designing hospital technology instruments with Instrumentarium-based Datex in 1978. According to Nikkanen, in addition to the form and user features, the design of instruments need to pay special attention to the design of user interfaces. Information needs to be clear and unambiguous, so that the nursing staff can operate quickly and correctly even in critical situations.
