| 摘要 |
The present invention relates to a fiber optic connection (1) between a sensor-guide portion (2) comprising an optic fiber (4) arranged in an air channel, said optic fiber (4) leading to a sensor element in the farther end of said sensor-guide portion (2), and a connective portion (3) comprising an optic fiber (8) arranged in an air channel, said optic fiber (8) leading to an electronic unit, wherein said optic fiber (4) said sensor-guide portion (2) and said optic fiber (8) of said connective portion (3) being aligned against each other in fixed, light transmitting position when said connection (1) is closed, and an outwards pressure tight air channel (11) is formed in the closed position of said connection, said air channel (11) extending continuously from said electronic unit to said sensor element via said connection (1). Furthermore, the invention relates to use of the connection (1) during intravascular pressure measuring, especially of artherosclerotic vessels. |
