Abstract

A medical diagnostics installation has an examination station at which a patient and medical examination equipment are disposed, and a control console disposed remotely therefrom. At least two different wireless control signal transmission channels are provided, each sending control signals to the examination station simultaneously by means of different types of information-carrying signals, such as an ultrasound signal and an infrared signal. Since the different types of information-carrying signals are affected by respectively different types of disturbances in the transmission path, the risk of an incoming control signal being misinterpreted due to the presence of a degraded signal is minimized.

Claims

1. A medical diagnostics installation comprising:

examination means for conducting a medical examination of a patient including at least one remotely controllable component, said remotely controllable component having means for receiving control instructions connected thereto;

control means for wirelessly remotely transmitting control instructions to said means for receiving, said control means including means for generating a first type of information-carrying signal in which said control instructions are encoded and means for generating a second type of information-carrying signal in which said control instructions are encoded, and means for simultaneously transmitting said first and second types of information carrying signals to said means for receiving; and

recognition means, connected to said means for receiving, for permitting execution of a control instruction by said controllable component only when the instructions respectively received from said means for generating a first type of information-carrying signal and said means for generating a second type of information-carrying signal are identical.

2. A medical diagnostics installation as claimed in claim 1 wherein said means for generating a first type of information carrying signal is an infrared transmission signal generator and wherein said means for generating a second type of information-carrying signal is an ultrasound emission generator.
