PROBLEM TO BE SOLVED: To enable the visual recognition of an actual flow rate, in a capacity control type infusion pump.SOLUTION: In a capacity control type infusion pump, a dropping sensor 8 for detecting a droplet dropping in a drip tube 100 disposed on an upstream side in an infusion feeding direction of a pump mechanism 2. A flow rate is calculated on the basis of the output of the dropping sensor 8, and the calculated flow rate (an actual flow rate) is displayed on a screen of a display portion. In this structure, a user such as a nurse can visually recognise the actual flow rate, so that the user can determine the deterioration of flow rate accuracy by comparing the actual flow rate with a setting flow rate. |
