CATHETER SYSTEM HAVING AN OPTICAL PROBE AND METHOD FOR THE APPLICATION OF AN OPTICAL PROBE IN A CATHETER SYSTEM

摘要

The invention relates to a catheter system having a flexible, elongated base body (2) that can be applied central-venously, a fiber-optic probe (8), a fiber-optic lumen for receiving the fiber-optic probe (8), and an attachment means (25) for avoiding a longitudinal displacement of the fiber-optic probe (8) relative to the fiber-optic lumen, wherein the attachment means (25) can be detached in order to allow a longitudinal displacement of the fiber-optic probe (8) relative to the fiber-optic lumen for removing the optical probe (8), wherein the attachment means (25) has a connector piece (7) that is firmly connected to the fiber-optic probe (8) and a counter-piece (6) that is firmly connected to the base body (2) that can be applied central-venously, which may be connected to each other, and wherein the distance between the distal end (3) of the central-venously applicable base body (2) and the distal end (14) of the fiber-optic probe (8)is adjusted to a predetermined value in the connected state by the firm connections between the fiber-optic probe (8) and the connector piece (7) as well as the base body (2) and the counter-piece (6), wherein additionally a shaft piece (30) that is adjustable with regard to the length thereof is provided on the connector piece (7), via which the length of the connector piece (7) and thus the length of the fiber-optic lumen may be varied.
