Abstract

A vascular access monitoring device for monitoring characteristics of a skin piercing vascular access device comprising: an acoustic sensor operable to detect an acoustic emission created by flow through said vascular access device and produce an electrical signal indicative of said emission; electronics processing means for processing and monitoring said electrical signal, and to determine, by identifying a change of characteristic of said signal, the possibility that the vascular access device has become dislodged from its normal working position.
