A biomedical joint device for the measurement of physical quantities comprises one tubular joint element provided with at least one connecting channel defining a first port, connectable to a biomedical device for the treatment of a body fluid, and a second port opposite to the first port; a sensor means, positioned adjacent to the second port and communicating with the connecting channel, adapted to detect at least one physical quantity characteristic of the body fluid; and one supporting element of the sensor associated with the joint element, to close said second port.

The present invention relates to a detection arrangement, comprising: an actuation element, which is designed to be moved back and forth between at least one first and one second position; a fastening portion, which is designed such that the actuation element can be brought into contact with a tube; a spring element, which interacts with the actuation element such that the spring element exerts a force on the actuation element in the direction of the second position; a retaining element, which interacts with the actuation element such that the actuation element can be moved into the first position by means of the retaining element; and a control element, which is designed to detect at least one parameter of the actuation element and/or of the retaining element and evaluate same so that the control element, on the basis of this evaluation, provides information about the condition of the detection arrangement.

A system and method for increasing the speed of blood and wall shear stress (WSS) in a peripheral vein for a sufficient period of time to result in a persistent increase in the overall diameter and lumen diameter of the vein is provided. The method includes pumping blood at a desired rate and pulsatility. The pumping is monitored and adjusted, as necessary, to maintain the desired blood speed, WSS and pulsatility in the peripheral vein in order to optimize the rate and extent of dilation of the peripheral vein.

An extracorporeal blood line set for a blood treatment machine or as part of a blood treatment machine, especially a dialysis machine. The extracorporeal blood line set includes an arterial blood line having a distal patient access and a proximal device port, preferably a dialyzer port, a venous blood line having a distal patient access and a proximal device port, preferably a dialyzer port, and at least one fluid supply line which is connected to the arterial and/or venous blood line(s) in at least one port section of the arterial and/or venous blood line(s) and at one end includes a container port or a fluid container. The at least one port section is in the form of a Venturi nozzle.

This document describes stepper motor drive systems. The stepper motor drive systems can be used in many different applications including, for example, to drive a stepper motor of an occluder device in association with a heart-lung machine.

Extracorporeal blood treatment apparatus with reservoir status lights and methods of monitoring reservoir status using the same are described. The extracorporeal blood treatment apparatus include a plurality of reservoir scales (30), each of which is configured to weigh a reservoir (32) used in connection with the extracorporeal blood treatment apparatus. A plurality of reservoir status lights (40) are provided, with one or more of the reservoir status lights (40) associated with one of the reservoir scales (30). The one or more reservoir status lights (40) associated with one of the reservoir scales (30) emit light from a location that is closer to their associated reservoir scale than to any other reservoir scale of the extracorporeal blood treatment apparatus.

The invention relates to a blood treatment device having at least one metering line which opens into a fluid circuit, wherein a conveyor module is arranged in the metering line and comprises a membrane pump and a valve which is arranged at the pressure side thereof and which can act both as a blocking valve and as a restricting valve.

This disclosure relates to a medical device including, a hard part, a converter, and a conductive path. The hard part has fluid paths for guiding a medical fluid, in particular blood, through the hard part. The converter is arranged to measure a characteristic of the medical fluid while the fluid is present in one of the fluid paths. At least a first section of the converter or of the conductive path is applied to or superimposed on the hard part by a first additive application method. At least a second section of the converter or of the conductive path is applied to the hard part by a second application method. The first and the second additive application methods differ from each other.

The disclosure relates to methods for therapeutically targeting circulating tumor cells during hemodialysis, comprising: connecting a patient's bloodstream to a flow electroporator device, the device comprising: an array of polymeric channels, where the opposing sidewalls of each channel are lined with discontinuous sections of electrodes, interspersed by non-conductive polymer sections to generate sequential electric fields by constant direct current voltages; sequential electric fields with independently regulated intensity, duration, and polarity to induce lysis of circulating tumor cells and deliver chemotherapeutic agents to reduce the viability of circulating tumor cells; and polymeric tubing inlet and outlet for seamless integration into the bloodline tubing of any hemodialysis machine

A display device for a medical apparatus including a projection surface arranged on the medical apparatus and configured to present a predetermined display content in a way visible to a user of the medical apparatus, and a projection device arranged on the medical apparatus and configured to project the predetermined display content from a rear side of the projection surface onto the projection surface. The projection surface and the projection device are configured as a head-up display unit for visual field presentation of the display content, and the medical apparatus may be an apparatus for carrying out extracorporeal blood treatment including the display device.
