The infusion drop-rate calibrator: a functional tester for drop-counting I.V. administration

Area of Science:

• Biomedical Engineering
• Medical Device Technology

Background:

• Infusion Units require calibration for accurate drug delivery.
• Current calibration methods often involve complex internal connections to the Drops indicator lamp.

Purpose of the Study:

• To develop a non-invasive device for dynamic testing of Infusion Units.
• To provide a fast, accurate, and simple method for calibrating infusion drop rates.

Main Methods:

• A novel Infusion Drop-Rate Calibrator was designed.
• The calibrator utilizes a photocell pick-up probe aimed at the Infusion Unit's Drops indicator lamp.
• The device counts lamp flashes and provides an audible signal for drop-sensor verification.

Main Results:

• The Infusion Drop-Rate Calibrator enables dynamic testing without opening the Infusion Unit.
• The device offers a fast and accurate method for assessing infusion drop rates.
• Audible feedback confirms the proper operation of the drop-sensor.

Conclusions:

• The Infusion Drop-Rate Calibrator is a valuable tool for simplifying and improving the accuracy of infusion pump calibration.
• This non-invasive approach enhances the efficiency and safety of medical device maintenance.
