▎ 摘　　要

NOVELTY - The catheter sensor (100) has a laser induced graphene sensing element (111) that is used for collecting hemodynamic information. An electronic module (12) is electrically connected with the laser-induced graphene sensing element and is used for receiving the hemodynamic information collected by the laser induced graphene sensing element and for transmitting the hemodynamic information to the terminal device (13). The sensing unit is provided with a first laser-induced graphene structure and a second laser-induced graphene structure. The first laser induced graphene structure is provided with a first interface micro-structure towards one side of the second laser-induced graphene. The second laser induced graphene structure is provided with a second interface micro-structure towards one side of the first laser-induced graphene. USE - Catheter sensor for blood detection system (claimed) for detecting blood flow dynamics information of patient and realizing tracking of cardiovascular health condition of patient. ADVANTAGE - The catheter sensor reduces the risk of implantation and improves the safety of hemodynamic information detection. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a manufacturing method of catheter sensor. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the catheter sensor.
