摘要：
[Problem] To provide a device for measuring blood flow in the spinal canal, the device being capable of being inserted into the spinal canal and easily measuring with high precision the amount of blood flow in the blood vessels supplying blood to the spinal cord. [Solution] Inside a catheter (11), which is provided with a tip section (11a) that can be placed in the spinal canal, a light-emitting optical fiber (12) and a light-receiving optical fiber (13) are provided so as to extend along the direction in which catheter (11) extends. The light-emitting optical fiber (12) is configured so as to be capable of emitting laser light from a light-emitting section (12a) at the tip and the light-receiving optical fiber (13) so as to be capable of receiving scattered light from the light-receiving section (13a) at the tip. A light-reflecting means (14) is disposed on an extension of the tips of the light-emitting optical fiber (12) and the light-receiving optical fiber (13). The light-reflecting means (14) is provided so as to reflect laser light from the light-emitting section (12a) and emit the light in a roughly orthogonal direction to the direction in which the spinal cord extends, and to reflect the scattered light from the roughly orthogonal direction to the direction in which the spinal cord extends and receive the light in the light-receiving section (13a).Le problème décrit par la présente invention est de concevoir un dispositif permettant de mesurer le flux sanguin dans le canal rachidien, le dispositif pouvant être inséré dans le canal rachidien et mesurer facilement, avec une haute précision, la quantité de sang circulant dans les vaisseaux sanguins qui alimentent la moelle épinière en sang. La solution selon linvention porte sur un cathéter (11), dont lintérieur est doté dune section dextrémité (11a) que lon peut placer dans le canal rachidien, dune fibre otique démission de lumière (12) et dune fibre optique de réception de lumière (13) qui sont disposées d
