The system which position of the distal (2036) edge of the tube for the blood vessel monitoring is done

摘要

The invention relates to a system (101) for monitoring a position of a distal end (102) of a tube (104) with respect to a blood vessel (106) of a mamma. The system comprises a source (110) for generating an outgoing beam (112) of electromagnetic radiation having a predefined electromagnetic spectrum. The system furthermore comprises a guideway (114) for guiding the outgoing beam to the distal end, and for guiding an incoming beam (116) of electromagnetic radiation reflected by surroundings of the distal end in response to said outgoing beam to a measurement arrangement (120) which is arranged for measuring a parameter (122) associated with an electromagnetic spectrum of the incoming beam. The system furthermore comprises a comparator arrangement (124) for comparing said parameter with a reference parameter (126) associated with a reference electromagnetic spectrum representing a predefined location of the distal end inside the mammal.
