Abstract
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.
Claims18
An apparatus for analyzing biologic fluid, comprising:
- a first planar member;
- a second planar member, wherein at least one of the first planar member and second planar member is transparent;
- and
- at least three separators disposed between the planar members, each separator individually having a height and the separators collectively having a mean height, separating the planar members to form a chamber having a height extending between the planar members;
- wherein the separators are sufficiently deformable when the first planar member and second planar member are drawn toward one another by capillary force from a biologic fluid quiescently residing within the chamber to cause the mean chamber height to be substantially equal to the mean height of the separators.
An apparatus for analyzing a biologic fluid, comprising:
- a first planar member;
- a second planar member, wherein at least one of the first planar member and second planar member is transparent;
- and
- at least three separators disposed between the planar members, each separator individually having a height and the separators collectively having a mean height, separating the planar members to form a chamber having a height extending between the planar members;
- wherein the separators and the first planar member are sufficiently deformable when the first planar member and second planar member are drawn toward one another by capillary forces from a biologic fluid quiescently residing within the chamber to cause the mean chamber height to be substantially unaffected by the presence of debris within the chamber, which debris has a height greater than the mean separator height.

- and
- at least three separators disposed between the planar members, each separator individually having a height and the separators collectively having a mean height, separating the planar members to form a chamber having a height extending between the planar members;
- wherein the first planar member and the second planar member have greater deformability than the separators, which deformability is sufficient when the first planar member and the second planar member are drawn toward one another by capillary force from a biologic fluid quiescently residing within the chamber to cause the mean chamber height to be substantially equal to the mean height of the separators.
