Abstract
An infusion apparatus is provided with a clock, a power-on-time counter for counting a period of time in which power is supplied to the infusion apparatus from an AC power source or a backup battery for backing up the AC power source, a pump-on-time counter for counting a period of time in which a pump mechanism operates, and a battery-on-time counter for counting a period of time in which power is supplied to the infusion apparatus from the backup battery. A CPU displays a time value counted by the counters on a display unit. The time value displayed on the display unit indicates the degree of deterioration of charge capability of the backup battery, from which a time for replacing the backup battery and the other parts can be easily perceived.
