20090205426 | Method and device for monitoring a flowing liquid for the presence of air - 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. | 08-20-2009 |
20100049114 | BLOOD TREATMENT APPLIANCE, STORAGE MEANS FOR USING WITH THE BLOOD TREATMENT APPLIANCE, AND COMBINATION OF THE BLOOD TREATMENT APPLIANCE AND STORAGE MEANS - The present invention relates to the field of blood treatment machines such as hemodialysis machines. The object of this invention is to improve upon a generic blood treatment machine such that a certain individualization of the treatment station with little or no expenditure of materials is made possible in order to make the treatment environment more pleasant for the patient to be treated on the machine. The inventive blood treatment machine ( | 02-25-2010 |
20100323724 | EXTRACORPOREAL BLOOD TREATMENT DEVICE AND METHOD FOR PREPARING BLOOD TREATMENT USING AN EXTRACORPOREAL BLOOD TREATMENT DEVICE - The present invention relates to an extracorporeal blood treatment device comprising a treatment unit and a device for controlling the treatment unit for preparing and carrying out the blood treatment. The blood treatment device also comprises an internal communication unit for communicating with an external communication unit. In order to the prepare the device blood treatment, the patient sends an initiation code by means of an external communication unit to the internal communication device. Routines required for preparing the blood treatment are then started. One main advantage is that the patient, for example during home dialysis, does not need to be present when the device is preparing for dialysis and the dialysis preparation can be started when the patient thinks of returning home in time for the beginning of the preparation phase. | 12-23-2010 |
20110230814 | METHOD AND APPARATUS FOR MONITORING A PERISTALTIC HOSE PUMP FOR CONDUCTING A FLUID IN A TUBING - The invention further relates to an apparatus and method for monitoring a peristaltic hose pump, in particular a peristaltic hose pump of an extracorporeal blood treatment device. The power consumed by the pump and/or the pressure in the tubing segment upstream or downstream of the pump is/are measured during operation of the pump and test signals I | 09-22-2011 |
20120091048 | CHAMBER FOR A BLOOD TREATMENT SYSTEM, BLOOD TUBING SYSTEM, AND BLOOD TREATMENT SYSTEM - The present invention relates to a chamber for a blood treatment system having a blood inlet and a blood outlet, a filter element for air separation which is arranged at the head side with respect to the position of the chamber in the operating state and which can be decoupled from the blood present in the chamber in the operating state by means of a further liquid, to a blood hose system and to a blood treatment system. | 04-19-2012 |
20120245555 | Blood tube section for extracorporeally carrying blood, extracorporeal blood circuit, treatment apparatus as well as methods - The present invention relates to a blood tube section for extracorporeally carrying blood during a blood treatment of a patient, wherein the blood tube section comprises at least one device for conveying blood, a drug solution or a liquid mixture within the blood tube section by deforming the tube diameter and sliding along an area of the blood tube section. The present invention further relates to an extracorporeal blood circuit, a treatment apparatus as well as methods for conveying blood, a drug solution or a liquid mixture and for supplying and/or administering and/or transporting an active substance. | 09-27-2012 |
20130274613 | METHOD AND DEVICE FOR RECOGNITION OF PARAVASAL BLEEDING - A method and a device for recognition of paravasal bleeding upon a supplying of blood to a vascular access via a line and/or upon the removal of blood from a vascular access via a line is provided. A device for extracorporeal blood treatment comprising a device for recognition of paravasal bleeding is also provided. The method and the device are based on the change of arterial pressure in the arterial branch or the venous pressure in the venous branch of the extra-corporeal circuit being registered during the extracorporeal blood treatment. One aspect of the method and the device is that pressure changes that come from a pressure level exhibiting a large difference from a reference value are more strongly considered than those that come from a pressure level that exhibits only a minor difference from the reference value. | 10-17-2013 |
20150182683 | CHAMBER FOR A BLOOD TREATMENT SYSTEM, BLOOD TUBING SYSTEM, AND BLOOD TREATMENT SYSTEM - The present invention relates to a chamber for a blood treatment system having a blood inlet and a blood outlet, a filter element for air separation which is arranged at the head side with respect to the position of the chamber in the operating state and which can be decoupled from the blood present in the chamber in the operating state by means of a further liquid, to a blood hose system and to a blood treatment system. | 07-02-2015 |
