Data acquisition from in vitro testing of an occluding medical device

This paper presents a technique for in vitro testing of an occluding medical device. The testing apparatus is equipped with a data and image acquisition system. The aim of the integrated components of the system is to measure the pressure of the fluid inside the testing tube and the displacement of the device inserted in the tube. National Instruments equipments and software were used. LabVIEW and Vision Assistant provided the tool for data and image acquisition and output the values for pressure and displacement. The entire system gives the necessary information to reach conclusions about the performances of the medical device and can be used in combination with the testing rig.
