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&#x2014;in particular, in combination with a comparatively precise measurement&#x2014;especially, pressure measurement. The measuring device may be produced according to a method and the measuring device may be used in a measuring method.

Measuring device and method for measuring a property of a fluid in a line

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.

Intermediate element for a medical extracorporeal fluid line, and system and method associated therewith

The invention relates to a medical technology measuring system () comprising a measuring device () for measuring a characteristic of a fluid&#x2014;in particular, for pressure measurement&#x2014;wherein the measuring device comprises a lead () which extends along a central longitudinal axis (M) and is equipped to guide a fluid&#x2014;in particular, blood&#x2014;inside a longitudinal cavity () enclosed by a wall, and a sensor device () comprising a sensor () which is equipped to measure a characteristic of the fluid guided in the longitudinal cavity, wherein the measuring system () has an overmolding () which at least partially surrounds the measuring device ()&#x2014;preferably, both at least the sensor device () and also a section of the lead (). As a result, the measuring device can be fastened and positioned on the lead in a simple and/or reliable, robust manner. The invention further relates to a method for producing such a medical technology measuring system.

Medico-technical measuring device and measuring method

An oxygenator comprising a hollow-fibre film bundle is surrounded at least in certain areas by a bubble-retaining filter. In order to ensure an optimal function of the hollow-fibre film bundle and the bubble-retaining filter, it is proposed that a gas-permeable retaining structure is arranged between hollow-fibre film bundle and bubble-retaining filter.

Oxygenator comprising a hollow-fiber film bundle

An oxygenator module for gas exchange between blood and a gas in an extracorporeal lung support system, with several layers of semipermeable, gas-perfusable hollow fibers, wherein the hollow fibers of one of the layers are oriented at an angle of rotation about a central longitudinal axis of the oxygenator module with respect to the hollow fibers of another one of the layers, and with a potting which extends along the central longitudinal axis and in which the hollow fibers are fixed, wherein the potting defines a cavity that extends along the central longitudinal axis and in which the hollow fibers are arranged and which is blood-perfusable in the direction of the central longitudinal axis, wherein the potting has an essentially circular inner sheath surface that limits the cavity radially outward; as well as a method for producing the oxygenator module.

The invention relates to a device () for the treatment of a biological fluid, comprising at least three chambers, wherein a first chamber (), which is provided for receiving the biological fluid, and a second chamber (), which is provided for receiving a gas, are separated from each other by at least one gas-permeable and liquid-impermeable membrane (), said membrane () being used to transfer gas molecules between the first and second chambers (), and wherein the first chamber () and a third chamber () are separated from each other by at least one liquid-permeable membrane () which is used to transfer one or more components between the first and third chambers (). The second chamber () is delimited or enclosed by the at least one gas-permeable and liquid-impermeable membrane () and is located inside the first chamber () or is substantially enclosed by the first chamber () such that the biological fluid surrounds the second chamber (). Similarly, the third chamber () is delimited or enclosed by the at least one liquid-permeable membrane () and is located inside the first chamber () or is substantially enclosed by the first chamber () such that the biological fluid surrounds the third chamber ().

Device for the treatment of biological fluid

The invention relates to a gas transfer device comprising at least two chambers and at least one gas-permeable and liquid-impermeable membrane, wherein the chambers are separated from one another by the membrane(s), and wherein the membrane(s) is/are structured on at least one side and channels and/or branching structures, in particular branched pathways, are formed on the membrane by this structure, the walls of which have a spacing of &#x2266;500 &#x3bc;m, preferably of &#x2266;350 &#x3bc;m, and more preferably of &#x2266;150 &#x3bc;m, and the proportion of the membrane surface area which comprises channels and/or branching structures having this spacing constitutes at least 50% of the total surface area of the membrane.
