Abstract: The portable sensor device is connected with the arterial pressure measurement catheter by way of a pressure hose. The electronic pressure sensor is accommodated in the sensor housing. The analog sensor signal is output to the patient monitor by way of a cable. Aside from the channel for the analog sensor signal, additional channels are provided for communication between sensor device and patient monitor. A bidirectional channel serves for writing to and querying the memory module, in which patient data, such as age, gender, height/weight, etc., can be stored. The three-way cock possesses the settings “M” (measurement operation) and “0” (calibration measurement), in which the contactor is brought into connection with the contact. The switching contact is transmitted to the patient monitor, which thereby automatically recognizes zeroing of the sensor.

Abstract: In a fiber-optic probe for intravascular measurements, e.g. oxygen saturation measurements, the fiber-optical core has only two fibers. A single fiber core is also possible. A reinforcement fiber improves stiffness, kink resistance and overall strength of the probe. The reinforcement fiber is arranged essentially parallel to the core fibers. The reinforcement fiber may also be wound around the core in a helical manner thus improving the mechanical properties to an even higher degree. The outside of the sheath is coated with an antithrombogenic coating for reducing the danger of clots forming at the surface. The reinforcement fiber may be made of carbon, metal, ceramics or aramide.

Abstract: A device for the continuous measurement of the flow rate of a liquid, in particular the urine of a living being, comprising at least two receiving containers (2, 3) for receiving the liquid, a tubular or hose-like connection part (4) at the lower end of the first receiving container (2), which connection part connects the first receiving container (2) to the second receiving container (3), a first seal (6a/6b) between the first receiving container (2) and the second receiving container (3) at the tubular or hose-like connection part (4), a second seal (7) at the lower end of the second receiving container (3), and a rising pipe (8) which is connected to the second receiving container (3), wherein a measuring device (10) arranged in the region of the upper end of the rising pipe (8).

Abstract: The invention relates to a catheter device with an integrated fiber optic, in particular for use in thermodilution measurement and pulse contour analysis. The device comprises an arterial catheter (2) with a suitable intravascular part and a suitable extravascular part and an optical sensor unit for combined pressure and temperature measurement at a measurement location at the distal end of the suitable intravascular part or proximate to the distal end of the proper intravascular part of the catheter (2). The optical sensor unit comprises a fiber optic conductor (11) that runs from the measurement location to a proximal port.

Abstract: The central venous sensor assembly comprises a catheter body with several proximal ports. The catheter portion placed in the vena cava superior is equipped with a proximal flux measurement unit, and the catheter portion placed in the vena cava inferior is equipped with a distal flux measurement unit. A first input channel supplies a measurement signal indicative of a flux vp to the evaluation unit from which the latter calculates a blood flow in the vena cava superior. Likewise, a second input channel supplies a measurement signal indicative of a flux vd to the evaluation unit from which the latter calculates a blood flow rate in the vena cava inferior. Due to continuity, the sum of the flow rates in the upper and lower central veins corresponds to the flow rate through the right heart and in the pulmonary artery and thus to cardiac output.
