Apparatuses and methods for extravasation detection
First Claim
1. A system for the detection of extravasation in an injection procedure, the system comprising:
- a first sensor positioned to detect extravasation in the vicinity of an injection site; and
at least a second sensor positioned to detect extravasation at a site other than in the vicinity the injection site.

Abstract
An apparatus for the detection of extravasation is positioned in a manner so that the vicinity of a site is available for palpation and is visible for visual inspection. Another embodiment of the apparatus improves the sensitivity of detection by positioning an energy source and a receiver between a first layer of a high dielectric material and a second lay of a low dielectric material. The apparatus may further include a third layer of a conductive material to shield the apparatus from stray capacitance. In addition, a system for detection of extravasation includes an array of sensors located at, adjacent to and/or remote from an injection site.
