Vacutainer blood collection tube drawing volume tester

The Vacutainer blood collection tube in clinical use is large and wide, and its quality is directly related to human health and life safety. It is one of the key indexes of the production enterprises because the drawing volume of blood vessel is directly affected by its use. To this end, the national standard yy0314-2007 has a clear regulation on the volume of blood vessel suction.

RDVT-01 Vacutainer blood collection tube drawing volume tester applies to the pumping volume of blood collection tube and it can accurately measure whether the drawing volume meets the standard in different elevations. .

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.

When a vacutainer tube is inserted into the holder, its rubber cap is punctured by the inner needle and the vacuum in the tube pulls blood through the needle and into the tube. The filled tube is then removed and another can be inserted and filled the same way. 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.
