Abstract
An improved optical probe for the invasive measurement of blood parameters is disclosed that minimizes reading inaccuracy due to mechanical stresses. An optical probe for the invasive measurement of blood parameters is typically made up of various sensors that end in a sheath. Each sensor is connected to a monitor via an optical fiber. The optical fibers are surrounded by a tube. In the region where the sheath adjoins the tube, the sheath is deformed by crimping such that a better mechanical contact (form-locking) between the sheath, the sensors, and the tube can be obtained, in order to avoid systemic errors caused by displacement of the optical fibers inside the sheath.
