A display device for indicating the internal pressure of a tube of an infusion device having an infusion drive 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. The display device includes a message indicator for displaying the internal pressure of the tube as detected by the sensor. The message indicator has a plurality of alphanumeric display elements each consisting of a plurality of segments. The display elements are used to display a value, in alphanumeric terms, of the internal pressure of the tube. Further, some of the segments of the display elements are used to display the quantitative change of the pressure as a bar graph.

The liquid transfusion apparatus according to the present invention includes a setting device adapted to respectively set a normal level of pressure of the fed liquid and an upper alarm level of pressure of the fed liquid, calculating unit for calculating a percentage of a difference between the detected level of pressure of the liquid and the set normal level to a difference between the set upper alarm level and the set normal level, and display unit for displaying the calculated percentage. The liquid transfusion apparatus is very useful for monitoring the pressure of the liquid which is being administered to a patient.
