The Vacutainer system is faster and easier to use, with greater versatility, and produces higher quality blood samples at a price comparable to the syringe system. The Vacutainer system is faster and easier to use, with greater versatility, and produces higher quality blood samples at a price comparable to the syringe system. The problems of blood contamination during blood collection and distribution with both systems are discussed.

BD Vacutainer plastic tubes provide a safe method of collecting blood and reduce the risk of tube breaks and sample spills, reducing the risk of exposure to bloodborne pathogens.

How does the Vacutainer system work?

As shown in the illustration, the main components of Vacutainer needles are the chamfer, shank, threaded tray, and rubber sleeve that cover the needle. Vacutainer technology was developed by Joseph Kleiner in 1947 and is currently being marketed by Becton Dickinson (B-D). The needle actually has a second, smaller needle, and when a Vacutainer test tube is pushed into the holder, its rubber cap is pierced. Vacutainers have the advantage of being manufactured with additives that allow multiple pipes to be removed easily and have a lower chance of hemolysis.

A vacutainer blood collection tube is a sterile glass or plastic test tube with a colored rubber stopper that creates a vacuum seal inside the tube and makes it easier to draw a predetermined volume of fluid.

Why is Vacutainer used for blood collection?

The latest trends in vacutainer development involve a stronger tubing material made from a plastic and polyethylene formulation. The collection process required that phlebotomists puncture the vein with a needle and then maneuver the blood into the glass tube. If more than one blood sample is required for the test, use numerous needles and vacuum tubes to ensure that the blood collection process is more efficient. This collection tube is generally used for glucose tolerance tests as well as for blood alcohol and lactic acid tests.

Because the sodium is present in the heparin tube, it may interfere with the test and result in an increased sodium level in the blood sample.

What are the three parts of a Vacutainer blood collection system?

In case of an accidental needle prick, wash the area immediately with antibacterial soap, squeeze blood out of the wound and contact your supervisor. Gel-containing tubes can be easily handled and transported after centrifugation without the blood cells and. Tubes often contain additives that mix with the blood when collected, and the color of each tube’s plastic cap indicates what additives it contains. These tubes are used for coagulation tests and must be completely filled to ensure the correct ratio of blood to anticoagulant.

When a tube is inserted into the holder, its rubber cap is pierced by this inner needle, and the vacuum in the tube draws blood through the needle into the tube.

What are the requirements for Vacutainer blood collection?

When more than one blood sample is required, multiple sample needles and vacuum tubes make blood collection easier and more efficient. There are numerous coagulation factors (factor VIII, factor IX, etc.) that are involved in blood coagulation. Since additives are not interchangeable, it is necessary to consult the sample requirements box of the individual test descriptions to determine the appropriate collection requirements for the ordered test. Immediately after removing the needle from the vein, gently touch the tip of the needle with one of the clean slides. This results in a small drop of blood about 1 to 2 mm in diameter, about the size of a match head.

The serum is obtained from coagulated blood that has not been mixed with an anticoagulant (a chemical that prevents blood from clotting).

After experiencing a variety of shortages, crises, and inefficiencies in the status quo of the procurement and distribution industry, I undertook the responsibility of building an interface for large organizations to abstract away uncertainty throughout their supply chain under most conditions.

We are focused on building a framework from which our teams of professionals on the ground can provide a new generation of procurement support and professional services for supply chain critical organizations around the nation.

We understand that the marketing process of critical supplies is a matter of national security and public safety. In this, we found our passion and mission: developing technologies, supplier networks, and platforms for the organizations that need it most.
