Abstract: A method and a device for continuous, noninvasive monitoring of an extracorporeal blood treatment, a patient's blood pressure or a quantity that correlates with the blood pressure is measured and compared with a predetermined limit value. If the measured blood pressure or its relative change drops below the predetermined limit value, an activation or deactivation signal is generated to initiate an intervention in the treatment sequence. The blood treatment machine therefore has a control unit. The continuous, noninvasive measurement of blood pressure is based on a determination of the propagation rate or transit time of the pulse waves produced by the patient's cardiac contractions and their propagation through the arterial system. To determine the pulse wave velocity or transit time, the blood treatment machine has an electrocardiograph and a device for detecting the pulse waves at a location on the patient remote from the heart.

Abstract: An extracorpeal blood circuit for removal of contrast from human blood using a filter and withdrawal filter pump and a by-pass pump. The withdrawal filter blood pump operates when a contrast bolus has been detected. Otherwise the bypass blood pump maintains physiological blood flow from the coronary sinus preventing the need for deflation and re-inflation of the balloon catheter. When contrast is detected blood the bypass blood pump is stopped to prevent contrast from leaking back into the patients circulatory system via the bypass pump and CS blood flow is maintained at its physiological blood flow resulting in the heart being oblivious to the transition by the prefilter blood pump.

Abstract: An assembly for separating solid phase material from a slurry that comprises a pressurized filtration unit including a vessel and filter media. A slurry is fed to the filtration unit where it is separated into a solid phase material and a liquid phase material. The filtration unit has a solid outlet for discharging the solid phase material to a material transport. The material transport moves the solid phase material to a depressurizing chamber that has a lower pressure than the filtration unit. As the solid phase material enters the depressurizing chamber it is exposed to the lower pressure of that chamber. The material transport maintains the pressure difference between the filtration unit and the chamber. Subsequently, the depressurized solid phase material can be conveyed to other equipment for drying or other processing.

Abstract: The valved filter assembly of the present invention utilizes a bi-directional pressure differential valve in fluid communication with a filter body housed within a container, such as a bottle. This unique structure allows the user to dispense filtered fluid from a bottle only when the bottle is inverted and squeezed. Squeezing the bottle causes the pressure to increase on the inside of the bottle thereby causing water to traverse the filter body thus contacting and opening the bi-directional pressure differential valve thereby allowing liquid to exit; however, when no pressure is applied to the bottle the bi-directional pressure differential valve remains in the closed position sealing the bottle.
