  • Patent number: 11357899
    Abstract: A medico-technical measuring device for measuring a property of a fluid, such as pressure for pressure measurement, includes a line extending along a central longitudinal axis to guide a fluid, such as blood, within a longitudinal cavity delimited by a wall. A sensor unit has a sensor and measures a property of the fluid guided in the longitudinal cavity. The line is provided with a radial cavity inserted in the wall in a radial direction, in which the sensor unit is at least partially arranged, and which is integrated in the wall such that the sensor is in communication with the fluid. In this way, a measuring device can be provided that allows simple handling—in particular, in combination with a comparatively precise measurement—especially, pressure measurement. The measuring device may be produced according to a method and the measuring device may be used in a measuring method.

  • Patent number: 11141516
    Abstract: The invention relates to a portable gas exchange device for gas exchange of at least one gas from a liquid to a fluid. The gas exchange device comprises a first gas exchange section, for passage of a fluid, and a second gas exchange section for passage of a liquid enriched with a first gas, wherein the fluid has a lower concentration of the first gas than the liquid. A pumping system for transporting a first fluid with a lower concentration of a first gas in the first gas exchange section, in particular in a first fluid circuit, is also configured in the gas exchange device. In a mixing chamber configured in the gas exchange device, the first gas exchange section and the second gas exchange section adjoin one another via a wall designed such that at least the first gas can pass through. A housing serves as the common receptacle at least of the pumping system and the mixing chamber.

  • Patent number: 10814054
    Abstract: An intermediate element for a medical extracorporeal fluid line designed to conduct a fluid, such as blood, has a main part extending between two connection parts. A flow channel passes continuously through the main part and the connection parts. The connection parts hydraulically connect the main body to a fluid line. On the periphery of the main part a receiving area is arranged, which is designed to receive a measurement value transmitter. An opening to the flow channel is defined in the receiving area and is sealed in a fluid-tight manner towards the receiving area by an elastic element. The measurement value transmitter is a gas sensor of a sensor device for measuring at least one gas contained in the fluid. The elastic element is a diffusion element, which is permeable to at least one gas. The diffusion element is bonded to an edge of the opening.

  • Publication number: 20150030502
    Abstract: An arrangement for extracorporeal life support is further developed in such a way that a pump actuating signal produces a wave-like surging and subsiding pump output for a pulsatile flow. The pump is preferably a non-occlusive blood pump, such as a diagonal pump, for example. In a preferred variant of embodiment the control signal is provided by an ECG. This allows the diastolic pressure to be increased in order to improve the oxygen balance of the heart muscle.
