US Patent 7850916 Disposable chamber for analyzing biologic fluids

An apparatus for analyzing biologic fluid is provided that includes a first planar member, a second planar member, and at least three separators. At least one of planar members is transparent. The separators are disposed between the members, and separate the members to form a chamber having a height. At least one of the members or separators is sufficiently flexible to permit the chamber height to approximate the mean size of the separators. During use, the biologic fluid to be analyzed is disposed within the chamber.
