摘要： A method is presented for checking the integrity of a hollow-fibre fluid filter, in particular a hollow-fibre dialyzer (1), which is constructed from a plurality of hollow fibres (15) enclosed by a membrane, with the steps of: perfusing the inside or outside of the hollow fibres (15) with a fluid, supplying the outside or inside of the hollow fibres (15) with a gas, wherein the gas has a higher pressure than the fluid, and determining a quantity of the gas which penetrates into the fluid through holes in the membrane. The method is characterized in that, after flowing through the hollow-fibre fluid filter (1), the fluid is channelled through a bubble trap (30), and in that a volume of gas (41) collecting in the bubble trap (30) during a predefined or predefinable reference period is determined. Furthermore, equipment for checking the integrity of a hollow-fibre fluid filter (1) is presented.

摘要： A membrane distillation (MD) system includes a sweep gas MD (SGMD) module and a knockout chamber. The MD module includes a feed inlet, a feed outlet, a condensing media inlet, and a condensing media outlet. The condensing media is sweep gas. The knockout chamber is positioned after the feed outlet. The knockout chamber includes a liquid inlet, a liquid outlet, and a vapor outlet. Direct gas phase stripping within the SGMD module leads to additional water evaporation at the knockout chamber and contributes to enhanced water or VOCs removal of the MD system.

摘要： A detoxification method for treating sepsis, microbial infections, and other inflammatory conditions includes the steps of inducing flow of patient blood through a blood treatment device consisting of a bioreactor inlet and outlet in fluid connection to the circulatory system of a patient. Biological agents including lipopolysaccharide (LPS) and extracellular adenosine triphosphate (ATP) contained within patient blood can be irreversibly detoxified by passage of patient blood over a bioreactor surface having attached or immobilized alkaline phosphatase enzymes and acyloxyacyl hydrolase enzyme, with the bioreactor being contained within the blood treatment device. The method uses continuous treatment of a patient's blood to convert LPS and extracellular ATP in blood into inhibitors of inflammation in vivo without adding any chemicals to the bloodstream of the patient.

摘要： Described is a gas exchanger with a restriction element or elements to reduce gas exchange as desired to avoid hypo-capnia and hyper-oxygenation in small patients. The gas exchanger includes a gas exchanger housing with an outer wall and a core which defines an inner wall and having a blood inlet for receiving a blood supply and a blood outlet. The gas exchanger also includes: a hollow fiber bundle disposed within the housing between the core and the outer wall; and a gas inlet compartment for receiving an oxygen supply and directing the oxygen supply to first ends of the hollow fiber bundle, wherein the gas inlet compartment includes at least one restriction element configured to allow the oxygen supply to reach only a portion of the hollow fiber bundle.

摘要： A method of operating a filtration unit of a filtration system includes



feeding, during filtration, feed water containing suspended particulate material to an inside of each of a plurality of hollow fibres through a first inlet and a second inlet of each hollow fibre while simultaneously removing a filtrate from an outside of each of the hollow fibres through an outlet of a filtration elements. In addition, the method includes feeding,
during back-washing, back-wash water to the outside of the hollow fibres through the outlet of the filtration element. Further the method includes discharging, in a first back-wash cycle, back-wash water containing entrained particulate material from the inside of the hollow fibres from one end thereof. Still further, the method includes discharging, in a second back-wash cycle, back-wash water containing entrained particulate material from the inside of the hollow fibres from the other end thereof.
