The present invention relates to an extracorporeal blood treatment device comprising at least one output unit for outputting at least one report to a user of the blood treatment device, wherein the blood treatment device is configured to output at least one report by means of the output device after the end of a specific period of time since the switching on of the blood treatment device and/or on the occurrence of a specific event, said report relating to one or more pieces of information relating to the validity of a test carried out at the blood treatment device.

The invention relates to a connecting piece for establishing a fluid connection between fluid-conducting lines for installation in a cut-out in a housing part of a medical device, in particular a dialysis unit. Furthermore, the invention relates to a medical device, in particular a dialysis unit, comprising a housing that comprises a housing part having a cut-out into which a connecting piece of this type is inserted. The connecting pieceaccording to the invention comprises a tubular bodythat is made of an electrically conductive material and can be inserted into the cut-outin the housing partA, the end piecesof which body are designed for the attachment of the fluid-conducting lines. The connecting pieceis distinguished by a terminal partfor attaching an electrical protective conductor or equipotential bonding system, the terminal partbeing electrically conductively connectable or connected to the tubular body. The terminal partallows an electrical connection cableto be directly attached to a protective conductor(PE conductor).

Connection piece for producing a liquid connection between liquid-conveying lines, and medical appliance with such a connection piece

A method of filling a container, preferably containing at least one concentrate, with the concentrate being formed such that it forms at least one liquid concentrate or a part of a liquid concentrate on its solution in or its mixing with a liquid, preferably water, the liquid concentrate or the part of the liquid concentrate being suitable for preparing at least one dialysis solution, includes filling the container via a balance chamber system of a dialyzer. The balance chamber system has chambers from which the liquid is conveyed into the container in the form of repeating cycles. The pressure of the liquid being conveyed is measured during a cycle of the filling phase of the container, and an alarm signal is emitted and/or the filling of the container is stopped if a measured maximum pressure in a cycle does not reach or does not exceed a limit value.

Method of filling a container

A container for dialysis concentrates, in particular acidic dry concentrates, has integral supporting elements. When these dry concentrates are dissolved directly by a dialysis machine to form liquid concentrates, the container must provide a volume of 4-12 liters. To impart the required stability to the container, the container includes the integral supporting elements, which manifest their supporting function only when the container is used on the dialysis machine.

Concentrate container having supporting elements

The present invention relates to a method and a device for monitoring a flowing medium, in particular the blood flowing in an extracorporeal blood circulation, for the presence of air, in particular micro-bubbles. A sequence of signal pulses or a continuous signal is injected into the flowing medium, and the signal pulses or continuous signal leaving the flowing medium are received. To detect micro-bubbles, a signal pattern that is characteristic of the variation over time of the received signal pulses or the continuous signal in a predetermined period of time is extracted from the signal received. The characteristic signal pattern is compared with one or more characteristic reference patterns, and the presence of air bubbles is determined if the characteristic signal pattern deviates from the characteristic reference pattern by a predetermined amount. Statistical characteristic variables, in particular the variance, are preferably determined from the signal patterns and compared with one another.
