The Handling Philosophy
The communication between the operator and the machine is
principally done via the buttons and the Information Display. The
operator selects options and gives the machine instructions by pressing
buttons. The machine shows information on the Information Display,
in the form of text, and on the buttons, which are either lit or not lit.
The Flow Diagram
The machine displays ongoing status during procedures by lighting
up the fl ow paths on the Operator’s Panel. There are two fl ow paths
in the Flow Diagram, the fl uid path and the blood path. The fl uid path
shows the status of the dialysis fl uid in different colours of light, and
the blood path lights up red when the machine has detected blood in
the venous blood line.
The Flow Diagram also plays an important role in the handling of the
machine as it constitutes the framework for the “ fl ow path thinking”.
This means that the function buttons are placed according to where
on the Flow Diagram they belong (the "blood buttons" are placed
along the blood path and the " fl uid buttons" along the fl uid path). All
operator actions should be preceded by the thought: "Is this action
related to blood, or is it related to dialysis fl uid?" By doing so the
function or parameter that needs to be accessed can easily be found on
the operators panel, as the function buttons are laid out principally
according to this rule.
The Buttons
As well as the previously mentioned " fl ow path thinking", the function
buttons are also placed according to how they are to be used. The
setting keys are placed within the Keypad next to the Information
Display or above and below the Blood Pump button . A lit function
button means that the function behind the button has been activated.
A fl ashing function button means a request to press it. Information
will then be displayed on the Information Display. A lit setting key is
a guide, meaning that it can be pressed to move further along on the
Information Display.
The On/Off button , and buttons used for activating procedures, are
placed in the upper left corner.
The "blood buttons" are placed along with the blood path of the Flow
Diagram, and the " fl uid buttons" are placed along with the fl uid path.
The alarm buttons are situated together at the lower left on the
Operator’s Panel. These are the Alarm button , the Attention button and
the Air Detector button . When alarms or attention alarms are generated,
the alarm buttons will be activated. The Mute button at the top of the
group is used to silence the buzzer.
The Blood Pump button is placed to the left, next to the Information
Display. The setting keys used for increasing and decreasing the blood
fl ow rate are placed above and below the button.
