ECCENTRICITY-BALANCING DIGITAL BIO DISC

A DBD(Digital Bio Disc) is provided to prevent the damage of DBD and smoothly perform a disease checkup by forming an eccentricity balancing part on the DBD so as to suppress the eccentricity of the DBD during high-speed rotation of the DBD. A DBD(1) is composed of a plurality of chambers(2-1,2-2,2-...

Summary:A DBD(Digital Bio Disc) is provided to prevent the damage of DBD and smoothly perform a disease checkup by forming an eccentricity balancing part on the DBD so as to suppress the eccentricity of the DBD during high-speed rotation of the DBD. A DBD(1) is composed of a plurality of chambers(2-1,2-2,2-3,2-4) for performing disease checkup and valves(3-1,3-2,3-3) provided at paths between neighboring chambers. An eccentricity balancing unit(4-1) balances the DBD(1) when the DBD(1) is rotated by ununiform arrangement of the valves(3-1,3-2,3-3). The eccentricity balancing unit(4-1) includes at least one of the first eccentricity balancing part of a weight balance type, the second eccentricity balancing part of an automatic eccentricity balance type, and the second eccentricity balancing part of a liquid type.
