The invention discloses a blood centrifugal
machine with a rotary device. The blood centrifugal
machine comprises a base, a connecting base, a housing, a centrifugal room, a
barrel body, a shaft body,a connecting rod, a connecting shaft, a
test tube, a cover body, a connecting slot, a fixed base, a top cover, a placing hole, a rotary shaft, a through slot, a connector, a connecting block, a drivebelt wheel, a motor I, a belt, a driven belt wheel, a telescopic device, a movable base and a connecting pin. According to the blood centrifugal
machine disclosed by the invention, test tubes with blood are symmetrically placed into the
barrel body separately, the cover body is fastened down, the motor I is started to drive the drive belt wheel to rotate, the drive belt wheel rotates to drive thedriven belt wheel to rotate through the belt, the driven belt wheel rotates to drive the fixed base to rotate through the rotary shaft, and the fixed base rotates to drive the
barrel body at the periphery and the test tubes inside the barrel body to rotate to separate blood; and a motor II can be additionally arranged to regulate an angle when the test tubes are centrifuged, so that blood separating effect is improved, and working efficiency and working progress of
medical staff are also improved.
