@ A monitor for the control and/or checking of two or more functions, (xxx, yyy), comprising means (6-8) for the setting of upper and/or lower limit values (e.g. 7d and 7c) for the said functions and or a desired value (e.g. 7a) for the same functions.
The monitor in accordance with the invention is intended primarily for the control of haemodialysis, that is to say the purification of the blood of patients with diminished renal function or wholly lacking such function.
The monitor in accordance with the invention is characterized in that two or more values are arranged to be set with the help of one and the same manoeuvring element, e.g. a simple wheel (6), which is combined with an actuating element. e.g. a so-called touch-controller (e.g. 7,8) for each value which is to be set.
The invention also comprises a monitor for the control and checking of one or more functions, comprising means for the setting of upper and/or lower limit values (e.g. 7d and 7c respectively) for the said functions and/or a desired value (7a) for the same functions, and separate means for the checking of the same values, characterized in that the said means for setting is adapted to act upon a first computer which is arranged with a first display for set values, whilst the means for checking comprises a second computer which is arranged with a second display for monitored values.
