La présente invention concerne un système de surveillance de données, comprenant : un capteur de pression, un capteur de température, un tube métallique, un tube de guidage, un moniteur de données et une gaine de guidage. Le capteur de pression et le capteur de température sont installés à l'intérieur du tube métallique. Le capteur de pression et le capteur de température sont connectés au moniteur de données. L'extrémité proximale du tube métallique est reliée à l'extrémité distale du tube de guidage. L'extrémité proximale du tube métallique est l'extrémité du tube métallique qui est proche du tube de guidage. Le tube métallique et le tube de guidage sont conçus pour pouvoir être insérés dans un canal de cavité de la gaine de guidage en séquence. Le système de surveillance de données de la présente invention permet une surveillance simultanée de la pression et de la température, et les données de surveillance peuvent renvoyer l'état réel de la pression et de la température dans le corps.
