20110021967 | DEVICE AND METHOD FOR MONITORING AN ACCESS TO A PATIENT - The present invention relates to a device and a method for monitoring a patient access, particularly for monitoring the venous vascular access in extracorporeal blood treatment where blood is withdrawn from the patient via a flexible arterial line which has an arterial needle or cannula, and provided to the patient via a flexible venous line which has a venous needle or cannula. The needle or cannula of the present invention is so designed that, due to the liquid flowing through the needle or cannula, air is drawn in if the needle or cannula is out of the vascular access, whereby sound is generated. A vascular access which is not in proper order is detected with great certainty and reliability by monitoring the surrounding environment for the occurrence of sound, particularly for the occurrence of the solid-borne sound which propagates along the flexible venous line of the extracorporeal blood circuit. | 01-27-2011 |
20110048101 | METHOD FOR CALIBRATING A SENSOR WITHIN AN ENCLOSURE; SENSOR, DISPOSABLE, AND TREATMENT DEVICE INCLUDING A LIKE SENSOR - The invention relates to a method for calibrating sensors, in particular RFID sensors, within an enclosure such as, e.g., a sterilization chamber.

20120175295 | BLOOD TREATMENT UNIT FOR AN EXTRA-CORPOREAL BLOOD TREATMENT APPARATUS - The housing of the blood treatment unit according to the invention holds both a blood pump and a semi-permeable membrane. The blood pump is an impeller pump. The impeller of the impeller pump is surrounded by a partition which divides the housing into two chambers. The semi-permeable membrane forms at least a part of the partition. It is therefore possible for an exchange of matter to take place between the blood which flows through the first chamber of the housing and the dialysis fluid which flows through the second chamber of the housing. The blood treatment unit is intended for an extra-corporeal blood treatment apparatus and has a particularly compact construction. | 07-12-2012 |
