摘要： An improvement in the degree of separation of constituent cell layers in a centrifuged sample of human blood is achieved by decreasing the natural water content of the red blood cells to increase their density or specific gravity. Thus the red cell layer packs more tightly and separates more completely from the next lighter cell layer adjacent thereto, i.e., the granulocyte layer.

摘要： A technique for generally determining the volume of a layer of a constituent material in a centrifugally separated mixture of material. A centrifuge tube is used to hold the material mixture and an appropriately shaped body is disposed in the tube in the zone occupied by the constituent material whose volume is to be measured. The body reduces the available volume within the tube which may be occupied by the constituent material, and thus expands the axial extent of the constituent material to make visual measurement of the constituent material more accurate.

摘要： The present invention relates to an apparatus, i.e. a device, for transferring a representative sample of a liquid containing particles into a chamber for analysis, such as for example, whole anticoagulated blood. The apparatus comprises an ante-chamber configured for receiving, containing, and transferring a portion of the sample to an analysis chamber. The chambers are continuous with each other, configured to allow the capillary flow of substantially the entirety of the contents of the ante-chamber into the analysis chamber to under-fill or substantially fill the analysis chamber. The apparatus can be conveniently configured as a disposable, single-use device, such as a dipstick, for performing both sampling and analysis from a single apparatus. The apparatus is useful for providing reliable and reproducible blood and body fluid analyses.

摘要： A method and device for analyzing a hematologic sample centrifuged within a capillary tube is provided. The device includes a tube holder, a sample imaging device, a processor, and a sample data display. The sample imaging device is operable to create a digital image of the sample within a region of the tube. The region is defined by substantially all of the radial width and axial length of the sample residing within the internal cavity of the tube in the region where the float resides after centrifugation. The sample imaging device is operable to produce signals representative of the image. The processor is adapted to produce information relating to bands of interest within the image based on the signals from the sample imaging device. The sample data display is adapted to display the results therefrom and/or a digital image of the sample within the region.
