The testing principle of blood vessel suction volume tester is shown in the figure below:
Vacutainer needle are double ended, with one side being encased in a thin rubber coating for safety. When the needle is screwed into the translucent plastic needle holder, the rubber needle is inside the holder, and the exposed needle will be inserted into the vein.

The amount of air evacuated from the tube predetermines how much blood will fill the tube before blood stops flowing.
RDVT-01 Vacutainer c is convenient in use, digital input, and the system will automatically keep constant pressure in accordance with the change of liquid level in the tank, so as to guarantee the accuracy of the test.
