20100087772 | BLOOD PROCESSING DEVICE AND METHOD FOR PURGING A SET OF BLOOD LINES ON A BLOOD PROCESSING DEVICE - The invention relates to a method for the emptying of a blood tubing set of a blood treatment device comprising an extracorporeal blood circuit including a membrane filter having a first chamber and a second chamber separated therefrom by a membrane, said first chamber being flowed through by blood in operation of the blood treatment device and said second chamber being flowed through by filtrate in operation of the blood treatment device, and said blood tubing set including an arterial blood tube and a venous blood tube which are both in communication with the first chamber of the membrane filter and which conduct blood from the patient to the membrane filter and from the membrane filter to the patient in operation of the blood treatment device, and comprising a substituate line which opens into the arterial blood tube and/or into the venous blood tube, and comprising a substituate pump which is in communication with the substituate line such that it conveys substituate from a substituate source through the substituate line, wherein, for the purpose of emptying the blood tubing set, the arterial blood tube and the venous blood tube are connected to one another such that a circuit including the membrane filter, the arterial blood tube and the venous blood tube arises, that the substituate line is disconnected from the substituate source and that air or gas is pumped into the blood tubing set by means of the substituate pump so that an excess pressure arises in the blood tubing set by which liquid is displaced into the second chamber of the membrane filter via the membrane of the membrane filter. The invention furthermore relates to a blood treatment device. | 04-08-2010 |
20100168640 | Method for at Least Partially Draining an Extracorporeal Blood Flow and Haemodialysis Device for Use With Said Method - The invention relates to a method and a hemodialysis machine for at least partial emptying of an extracorporeal blood circulation after the blood of a patient in the extracorporeal blood circulation has been returned to the patient with the help of an infusion liquid which displaces the blood and after the patient has been separated from the extracorporeal blood circulation. The object of the invention is to empty at least the blood chamber of a hemodialyzer ( | 07-01-2010 |
20100264086 | METHOD AND APPARATUS FOR MONITORING THE SUPPLY OF REPLACEMENT FLUID DURING AN EXTRACORPOREAL TREATMENT OF BLOOD - An apparatus and a method for monitoring the supply of replacement fluid during an extracorporeal treatment of blood is disclosed. Detection of the supply of replacement fluid upstream or downstream of the dialyser or filter is based on a measurement of the optical or physical density of the blood or of a constituent of blood in the extracorporeal circulation. To detect pre- or post-dilution, the blood flow rate and/or the replacement rate and/or the flow rate of the fluid removed from the blood through the dialyser membrane is altered, and the density of the blood or of the constituent of blood is measured upstream and/or downstream of the dialyser. Additionally, an apparatus for treating blood with an apparatus for monitoring the supply of replacement fluid is disclosed. | 10-21-2010 |
20120298580 | METHOD FOR RINSING AND/OR FOR FILLING A BLOOD TREATMENT DEVICE AND BLOOD TREATMENT DEVICE - A method is provided for rinsing and/or filling a blood treatment device, in particular for priming such a device. The blood treatment device includes at least one membrane filter, in particular a hollow fiber membrane filter, at least one first partial circuit, and at least one second partial circuit, with the first and second partial circuit being separated by the membrane filter in a semipermeable manner. The first partial circuit is first filled with a fluid with a uniform and/or a pulsatile first volumetric flow rate that does not exceed a specified threshold value. At this value the fluid has not yet completely wetted and/or soaked the membrane, and/or the second partial circuit is at least temporarily open towards the atmosphere, and air is displaced from the first into the second partial circuit via the membrane filter, and/or during filling no negative pressure is applied to the first partial circuit. | 11-29-2012 |
20130025357 | METHOD FOR DETERMINING AT LEAST ONE PARAMETER OF AN EXTRACORPOREAL BLOOD CIRCUIT AS WELL AS APPARATUSES - A method for determining at least one parameter of an extracorporeal blood circuit includes the steps of filling an extracorporeal blood circuit, e.g., encompassing a medical functional device, a treatment device and/or a blood tube set, by introducing a fluid, and detecting a volume of the introduced fluid which is required for filling the extracorporeal blood circuit by a detection device. A control device, a treatment apparatus, a computer readable storage medium, a computer program product as well as a computer program are also described. | 01-31-2013 |
20130025697 | Method for removing fluid from a blood filter at the end of a blood treatment session and treatment apparatus for executing the method - The present invention relates to a method for removing fluid from a blood filter which is used for the blood treatment of a patient and/or for removing blood from an extracorporeal blood circuit at the end of a blood treatment session. It further relates to a medical treatment apparatus with a control and/or regulating device which executes the method according to the present invention. It further relates to a digital storage medium, a computer program product as well as a computer program for executing the method according to the present invention. | 01-31-2013 |
20130030344 | METHOD AS WELL AS APPARATUSES FOR REMOVING GAS ACCUMULATIONS FROM A COMPONENT OF AN EXTRACORPOREAL BLOOD CIRCUIT - The present invention relates to a method for removing gas accumulations from a component of an extracorporeal blood circuit, a control device for executing a method according to the present invention, a medical treatment apparatus which comprises at least one control device and/or stands in signal transmission or is connected for signal transmission with it, a digital storage medium, a computer program product as well as a computer program. | 01-31-2013 |
20130079698 | METHOD OF INITIALISING AN APPARATUS FOR BLOOD TREATMENT IN THE SINGLE-NEEDLE MODE AND APPARATUS FOR BLOOD TREATMENT IN THE SINGLE-NEEDLE MODE - An apparatus and method for blood treatment for the single-needle mode, the apparatus having an extra-corporeal blood circuit with a blood infeed line running to the inlet and a blood return line leading away from the outlet, of a blood treating unit, includes in the blood return line a device, e.g., container, for amassing blood, which is in flow-permitting connection for gas transfer with a device, e.g., container, for storing gas. A pressure is calculated and set in the device for storing gas before the arterial and venous phases are started, with two constraints. First, the pressure should be sufficiently low to ensure both no infusion of air into the patient and also regulated flow of blood into the patient even at opposing pressures lower than ambient pressure. Second, the pressure should be sufficiently high to expel blood from the device for amassing blood into the device for storing gas. | 03-28-2013 |
20140209520 | METHOD OF MANUFACTURING A CONCENTRATE - The present invention relates to a method of providing at least one concentrate of at least one dissolved substance for producing at least one dialysis solution, with the method comprising the following steps: providing at least one container containing at least one solid to be dissolved; supplying water into the container for dissolving the solid; draining the concentrate of the dissolved substance from the container and topping up with water; measuring the concentration of the dissolved substance or of a parameter correlated with the concentration; and temporary or permanent suppression of the topping up of water into the container when the measured concentration value of the dissolved substance falls below a first limit value or the value of the parameter falls below or exceeds a first limit value or when the change in the concentration value of the dissolved substance or of the value of the parameter exceeds a first limit value. | 07-31-2014 |
