    摘要： A method for the return of blood from a blood treatment apparatus, preferably from a dialysis apparatus, uses a pumped substituate fluid to displace the blood. A substituate pump contained in the treatment apparatus displaces the blood by means of the correspondingly transported substituate fluid until it is detected in corresponding detectors that substituate fluid is flowing back in the line instead of blood. Once the transported substituate fluid has been detected, the blood volume is further displaced in a controlled manner until it has reached the line outlet of the corresponding line.

    摘要： A method is provided for monitoring the introduction of substitution fluids for an extra-corporeal blood processing device with an extra-corporeal blood circuit, comprising an arterial blood line, running from an arterial patient connection to a first chamber of a dialyzer or filter divided into said first chamber and a second chamber by a membrane and a venous blood line, running from the first chamber of the dialyzer or filter to a venous patient connection. A device is provided for monitoring the introduction of substitution fluids for an extra-corporeal blood processing unit with an extra-corporeal blood circuit and an extra-corporeal blood processing device with a device for monitoring the introduction of substitution fluids. The method and the device for monitoring the introduction of substitution fluids are based on monitoring the fluid level in the bubble trap, arranged in the venous blood line of the extra-corporeal blood circuit. The method and the device require that fluid is added to fill the extra-corporeal blood circuit, for example, for a rinsing procedure of the extra-corporeal blood circuit by means of the substitution fluid supply line arranged upstream or downstream of the dialyzer. A pre-dilution can be commanded when, after initiating the rinsing process the fill level in the bubble trap does not drop below a certain level. When by contrast the fill level drops below a given level a post-dilution can be commanded.

    摘要： The present invention relates to a method for the operation of a pressure measuring device for the measurement of the pressure in a system through which fluid flows, in particular in an extracorporeal circuit of a medical unit, with the pressure measuring device having a measuring chamber which is bounded by a flexible membrane, through which fluid flows in the operation of the system or which is filled with fluid and also having a pressure sensor connected to the membrane for the purpose of pressure measurement, with the method including the following steps not requiring any intervention of the staff: a. increasing the pressure in the measuring chamber (12) to a pressure value at which the membrane (13) is at least slightly outwardly curved relative to the measuring chamber (12) in the state not connected to the pressure sensor (14) or determining such a pressure value; b: separating the membrane (13) of the measuring chamber (12) from the pressure sensor (14); c. joining together the membrane (13) of the measuring chamber (12) and of the pressure sensor (14) such that the membrane (13) of the measuring chamber (12) contacts the pressure sensor (14); and d. repeating the steps a. to c. at predetermined intervals and/or on the occurrence of an error case.

    摘要： A valve for the closure of fluid channels, in particular for use in disposable cartridges for extracorporeal circulations, having a valve body with a pressure channel, and a sealing cap, which can cooperate with the valve body in such a way that it closes off the end of the pressure channel on the valve body side against the surroundings. The valve is designed in such a way that a pressure chamber can be formed between the pressure channel and the sealing cap, and the sealing cap has a deformable sealing area for entry into a fluid channel in order to close the latter. The valve may be incorporated within a device for use with a disposable cartridge for at least one fluid channel.
