TUBITAK-UME
TUBITAK is the National Metrology Institute of Turkey. By participating to the MeDD-project they hope to extend their knowledge about micro flow rates and also to be able to service the health sector for accurate drug delivery.
Mrs Başak AKSELLİ has noticed an increasing demand of calibration and testing services for medical devices from hospitals and suppliers of medical equipment in Turkey. “To be able to satisfy this grooving demand we need to expand our calibration range. This project will lead to better primary and secondary standards for micro and nano flow rates.”
But according to Mrs Akselli, the project will also show the importance of metrology to the health sector: “We have noticed that people in the health sector do not know much about metrology and the importance of accurate measurement. MeDD will show the importance of flow metrology to both suppliers and end users of drug delivery devices.”
TUBITAK will contribute to the MeDD-project by developing a new standard based on the so-called micro-PIV technique: “We have developed a micro-PIV system which is an optical flow measurement technique. For PIV measurements, the fluid of interest is seeded with tracer particles that are illuminated by a sheet of bright light. The positions of these particles at different times are recorded by a camera. By measuring the particle displacements, the motion of the fluid can be ascertained. We will employ this technique to measure the flow rates in micro channels/pipes for steady and unsteady flow conditions. Unsteady flow investigations, which are mainly the pulsations created by pumps, is one of the challenges when talking about Metrology for Drug Delivery.”
