摘要： An apparatus and method are provided for diluting a concentrated solution to be analyzed which includes a Y-coupling for combining a diluent and the concentrated solution to form a mixture. The mixture is then divided into first and second parts, such as by a pumping arrangement, with the second part of the mixture being proportional in quantity to the quantity of concentrated solution. The first part of the mixture is then supplied to an analytical device for analyzing the mixture. A chamber including a movable wall element is provided which divides the chamber into two subchambers. The first part of the mixture is supplied to the subchamber on one side of the movable wall element, which causes the movable wall element to force a proportional quantity of diluent out of the subchamber on the other side of the movable wall element. The dispensed diluent is then conveyed to mix with the concentrated solution.

摘要： A method is provided for sampling and measuring the content of a low-molecular weight compound, such as glucose, cholesterol, or urea, in a complex fluid medium to be sampled, such as blood. A dialyzer is placed in contact with the complex fluid medium so that it passes through the dialyzer. One or more semipermeable membranes are disposed within the complex fluid medium to form one or more passageways for the passage of dialysis fluid, with the passageways being substantially smaller in volume than the volume of the surrounding complex fluid medium. A fractional portion of the complex fluid medium is acted on by the dialysis fluid and dialyzed so that only a fractional portion of the low-molecular weight compound diffuses into the passageways containing the dialysis fluid to produce a dialysate in the passageways. The dialysate is then measured to determine the content of the low-molecular weight compound in the complex fluid medium.

摘要： A process for the treating of and/or removal of substances from a liquid, especially whole blood, via a semipermeable microporous membrane (13, 14, 15) through adsorption and/or biological reaction by means of a biologically active material. Said whole blood is exposed to pressure variations at the membrane surface in a way such that a penetrating fraction of said whole blood is flowing in an alternating flow path through the membrane walls for contacting said biologically active material.Said biologically active material is asymmetrically immobilized in and on the surface of the side of said membrane that faces away from said whole blood. Alternatively, said biologically active material may be bound to an unsoluble matrix behind said membrane.Said membrane is for example provided within a casing (7, 8, 9) comprising inlet (10) and outlet (11) for said whole blood. The space between said casing and said membrane is via a connecting nipple (12) in communication with for example an expansion chamber for the provision of pressure variations.By means of the device (3) it is possible to perform said process in one and the same step and by means of one and the same pumping system.

摘要： A method and apparatus is provided for measuring the content of a compound in a liquid medium, and which is particularly useful for measuring the concentration of a low molecular weight compound in a complex medium in which there is provided a dialyzer in contact with the complex fluid medium and through which dialysis fluid is conducted to receive by diffusion a portion of the low molecular weight compound to produce a dialysate. The dialysate with the low molecular weight commpound to be examined is first conducted through a venting device for removal of gaseous particles therefrom before conduction through a reaction chamber containing enzymes for promoting the conversion of the low molecular weight compound in the dialysate into a converted reaction product. The dialysate is then conducted from the reaction chamber to a measuring unit for measuring the concentration of the converted reaction product in the dialysate conducted from the reaction chamber, the concentration of the converted reaction product being representative of the content of the low molecular weight compound in the complex fluid medium.
