Blood treatment apparatus with alarm device

摘要

A supervisor (41) is capable to detect alarm condition that is activated with the highest alarm point. A function supervision device is activated over the supervisor and the alarm system in failure of the alarm system. The actuators are used for execution of variations in the blood circulation. An alarm table is formed in the controller and the supervisor (41), that contains alarm conditions which are detected with the sensors of the controller (40) and/or supervisor (41). The alarm systems are steered from the controller. The alarm point exhibits sound characteristics in different frequency and/or sound rhythm. The alarm is stopped by using an alarm emergency key for a given time. The alarm is produced as a function of the alarm conditions contained in the alarm table. A scanning of the sensors takes place in fixed time intervals.
