Abstract: An injection system for injecting an injectate fluid into a blood vessel of the patient and for carrying out a blood pressure measurement of a patient. The injection system includes a catheter tube having a first end for penetrating the blood vessel of the patient, and a pressure sensor which is arranged close to a second end of the catheter tube and can sense a pressure of a liquid in the catheter tube as an indication of the blood pressure of the patient.

Abstract: A catheter system includes a flexible, elongated base body adapted to be applied to a vein central-venously and having a base distal end; a fiber-optic probe having a probe distal part; a fiber-optic lumen receiving the fiber-optic probe; and an attachment element configured to avoid a longitudinal displacement of the fiber-optic probe relative to the fiber-optic lumen and configured to detach so as to allow removal of the fiber-optic probe through the longitudinal displacement of the fiber-optic probe relative to the fiber-optic lumen. The attachment element has a connector piece firmly connected to the fiber-optic probe and a counter-piece firmly connected to the base body, wherein the connector piece is connectable to the counter-piece, the connector piece having a shaft piece adjustable lengthwise and disposed on the connector piece so as to vary a length of the connector piece.

Abstract: An injection channel for a blood vessel catheter for injecting an injectate fluid into a blood vessel of a patient for carrying out thermodilution orother dilution measurements in order to determine hemodynamic parameters of the patient. The injection channel includes a pressure sensor for sensing the central venous pressure of the patient wherein. The pressure sensor also senses a threshold of pressure in the injection channel as instants of begin and end of an injection process.

Abstract: A tube-like reflector insert for a sensor is located in a rigid, light-absorbing sleeve that is closed on one side, and forms a two-part reflector body with the sleeve. A nut is glued onto the open side of the sleeve to enclose the reflector insert. The intravasal part of the sensor is guided in a protective tube having connector threads glued on on both sides. This protective tube is screwed onto the Y connector piece and the reflector sleeve with the nuts. The tip of the sensor is inserted with slight play into the sensor cavity of the reflector insert. The play ensures that sterilization gas can reach all of the intravasal surfaces. The reflector is attached to the sensor via a screw connection outside of the intravasal region, which ensures that the intravasal sensor part is not exposed to clamping stress. Free access for sterilization gas is possible at all intravasal surfaces of the sensor.
