Abstract
Official abstract text for this publication.
An apparatus for monitoring whether or not a distal end of a tube is positioned inside a blood vessel includes a heating element configured to heat the tube distal end, and a sensor arrangement configured to generate a measurement signal indicative for heat transferred by exterior of the distal end. The apparatus further includes a comparator configured to compare the measurement signal with a reference level. The reference level equals a value attained by the measurement signal in response to a minimum flow velocity in the blood vessel. Further, a system is configured to exchange a liquid with a mammal via a blood vessel. The system includes the apparatus having the tube.
First claim
Opening claim text (preview).
The invention claimed is: 1. A system for exchanging a fluid, comprising: a tube having an opening at a distal end of the tube for flow of the fluid though the tube for introducing into or removing from a blood vessel the fluid, the tube including an apparatus for monitoring a position of the distal end of the tube with respect to the blood vessel to ascertain whether or not the distal end is located inside the blood vessel, the apparatus comprising: a heating element configured…
