Title: Device for the measurement of erythrocyte deformability
Inventor: KIESEWETTER HOLGER DR
IPC: G01N27/02
Filed: 1983-04-19
Granted: 1987-01-15
Abstract: For measuring the deformation capacity of erythrocytes use is made of a sample vessel that is walled off into two spaces by a piece of foil with a pore therein. One such space is filled with buffer solution with erythrocytes and the other is filled with buffer solution without erythrocytes. A pressure head is produced acting across the foil for causing transit or passage of the erythrocytes through the opening, whose diameter is less than the major quiescent diameter of an erythrocyte so that information on the deformation capacity may be produced by measuring the transit time. This is done by electrodes placed on the two sides of the opening so that changes in the resistance to alternating current by an erythrocyte in transit may be sensed and the transit time taken. After about 200 transits the readings are processed in a processing unit.
