Display device for indicating the internal pressure of the tube of an infusion pump

A display device for indicating the internal pressure of a tube of an infusion device having an infusion drive means for supplying an infusion fluid from a solution container to the human body through the tube and a sensor for detecting the internal pressure of the tube, comprising:

• a message indicator for displaying the internal pressure of the tube detected by said sensor;
• said message indicator including at least one row of alphanumeric display elements for selectively generating a text display, a digital display, or a bar graph display, and being indicative of the qualitative change and the quantitative change in the internal pressure of the tube as detected by said sensor;
• said bar graph display further being used to display the quantitative change in the sensor detected pressure;
• wherein said at least one row of display elements of said message indicator comprises an upper row and a lower row of alphanumeric display elements;
• said display elements of the upper row being used to generate a text display of information regarding the operating condition of the tube and the upper half segments of the display elements of the lower row being used to also display text information regarding the internal pressure of the tube while the segments of horizontal bars in the lowermost line of the lower row are used to display a bar graph of the internal pressure of the tube.
