Monitoring device for medical apparatus

The signal is to be limited to the persons monitoring the apparatus to the extent possible and should not disturb persons not involved or present in the same room, from any delicate work they may be doing. Freedom of movement of the monitoring persons is to be preserved. To accelerate corrective measures, the signal gives them information which is easy to understand about the type of disorder. For this purpose the signal transmitters for the monitored limit values are connected to a signal converter, through which a describing text in intelligible language is assigned to each signal case. These announcements are conveyed to the monitoring persons through an output means movable with them and limited to their area, such as single earphones. The earphone is connected to the signal converter through a wireless or wire-bound movable connection.
