While the problem of needle dislodgement was not new, the project team was able to look at it from an independent viewpoint. Instead of trying to measure what was going on inside the body or the dialysis equipment, the new device was designed to keep an eye on the access point monitoring for the first sign of blood loss. Using fibre optic technology designed for this exact purpose, the blood loss detection device proved to be highly effective and user friendly, with no more than an on/off switch.
