Device for measuring the flow rate of ringer solution

A method for measuring a flow rate of Ringer's solution using a device for measuring a flow rate of Ringer's solution, in which a user makes an input each time when a drip 23 drops in a drip chamber 22, an elapsed time is calculated when the input is made for a preset number of times, and a quantitative flow rate is acquired according to a preset volume of each drip 23, the method comprising the steps of:

• (P10) starting to check a time interval from when a first input is made;
• (P20) continuously receiving inputs for a preset number of times after the first input is made in step P10 and storing time intervals every time when the inputs are made;
• (P30) calculating a time elapsed for receiving the inputs for the preset number of times;
• (P40) converting the preset number of times for the elapsed time calculated in step P30 into the number of drips per an hour;
• (P50) calculating a flow rate of Ringer's solution per an hour by multiplying a preset volume of each drip 23 and the number of drips per an hour converted in step P40, and outputting the calculated flow rate of Ringer's solution;
• and
• (P60) storing a time interval when an input is additionally made within a predetermined time after step P50, and returning to step P30 by deleting the first time interval that is used when calculating the elapsed time in step P30 and allowing the stored time interval to be used in calculation of an elapsed time.
