PLASMA SEPARATOR AND USE THEREOF

摘要

PURPOSE:To separate plasma from a small amount of a blood handily while compacting the equipment by employing a cylinder filled with a filter material. CONSTITUTION:A cylinder 2 made of plastics with a bottom plate 3 is placed on a transparent glass plate 1 and filled with a filter material 4 in a layer. The back of the bottom plate 3 is made higher in the smoothness to fully reflect an incident light. A whole blood dropped into a sunk portion 4a for storing blood in several drops flows downward based on own gravity and the capillary phenomenon of the filter material 4. The filter is formed coarse in the upper layer and close in the lower layer so that blood cells are retained in the upper layer while the plasma passes through a drilled hole 3a and expands in a void 5 as thin film. The separation of the plasma can be done handily without use of any large centrifugal separator or the like.
