lagu Infusion Pump Tester completes tests according to IEC 601.2.24 standard. This includes taking flow measurements every 30 seconds so that the measurements are independent of the infusion pump’s flow rate. lagu is capable of detecting volume variations of 0.18 μl in a range of 0.10 ml/h to 1000 ml/hr.
The 2 channel lagu is a true dual channel infusion pump tester. Each channel is operated independently using its own measuring system.
lagu can test all types of infusion pumps. It carries out flow tests, bolus tests and occlusion alarm tests.
PRO-Soft lagu software lets you to remotely control one of the channels from a PC. It allows you to create automated test sequences, run the tests, print the results, and/or store them to disk. With PRO-Soft lagu, you may automatically test infusion pumps over long periods and against various loads. PRO-Soft is also designed to retrieve information from an equipment management database and update the database with test results.

Measurements
Infusion pump testers calculate flow rate from the measured time period to fill up a defined volume. If it takes 1 hour to fill up a defined volume of 10 ml, the flow rate is calculated to be 10 ml/h. This flow rate is called the instant flow rate. The minimum volume detection of this measurement is 10 ml, since it needs 10 ml to get the instant flow rate calculated. The next instant flow rate calculation may be done when an additional volume of 10 ml is delivered to the measuring device. When two or more instant flow rates have been obtained, the calculation of mean flow rate may be done by averaging the instant flow rates.
Sudden (not expected) flow change - importance of the minimum volume detection.
It is important to check out if the infusion flow is steady or not. It is important to detect any sudden (not expected) flow change. That’s what infusion pump tests are all about!
Detection of sudden (not expected) flow changes requires detection of tiny infusion volumes. As flow measurements may only be calculated every time the defined volume is filled up. Ability to detect small infusion volume gives a short time between each measurement, hence a high flowsampling rate. Ability to detect only larger infusion volume decreases the sampling rate and decreases the ability to detect sudden flow change. International standards describe flowsamplings to be done at every 30 sec. for all flow rates. This discloses any sudden (not expected) flow changes within 30 sec. to ensure a steady infusion from all types of infusion devices. To fulfill this requirement, minimum volume detection of the measuring device is critical.
Example:
To test the infusion pump against sudden (not expected) flow change at a flow rate of 10 ml/h with an accuracy of ± 2 %, the following minimum flow detection is needed:
Expected flow:
10 ml/h = 166.7 μl pr. minute (divide by 60) = 83.3 μl pr. 30 sec. (divide by 2)
2% of expected flow:
83.3 μl pr. 30 sec. x 2% = 1.67 μl pr. 30 sec.
A volume detection of 1.67 μl is required to detect a 2% sudden (not expected) flow change from an expected flow rate of 10 ml/h within 30 sec.
lagu - Minimum volume detection:
The minimum volume detection of lagu is 0.18 μl. That means less than 0.2 μl is needed for lagu to detect any sudden flow change in the range of 0.10 ml/h to 1000 ml/h.
lagu performs flow-samplings every second for all flow rates. We are proud to highlight this feature out of the many unique features of lagu.
