Abstract

The utility model discloses a blood collection tube for clinical testing, and specifically relates to the field of blood collection tube devices, comprising a device body and a turntable. The turntable is arranged inside the device body. The tube plug on the blood collection tube is inserted into the tube mouth of the blood collection tube for sealing, and the blood collection tube is placed in a placement groove. During the placement process, the blood collection tube will squeeze second clamping plates on both sides outward, thereby compressing a spring. After the spring rebounds, the second clamping plate clamps the blood collection tube. By rotating an adjustment handle, the first clamping plate is driven to move inward, and the first clamping plate drives the blood collection tube to be clamped, thereby fixing the blood collection tube. A starter motor drives the first rotating shaft to rotate, the first rotating shaft drives the driving gear to rotate, the driving gear drives the driven gear to rotate, the driven gear drives the second rotating shaft, and the second rotating shaft drives the turntable to rotate, thereby causing the blood collection tube to rotate. The centrifugal force generated by the rotation separates serum in the blood, thereby preventing the serum from being separated in time and affecting the test result.
