Disposable Vacuum Blood Collection Tube (Plain Tube)

Introduction

A disposable vacuum blood collection tube (plain type) is mainly used for venous blood collection and is particularly suitable for newborns. The tube has smooth inner walls that help reduce blood coagulation, ensuring the quality of the sample. It is made with high-quality vacuum tubes that contain stronger negative pressure, allowing venipuncture and blood collection to be carried out more smoothly. Since the plain tube has lower serum coagulation, it is suitable for routine biochemical tests.

However, it is important to note that plain tubes may be affected by external conditions, which can lead to lipemia, hemolysis, or even cell rupture. Therefore, the choice of tube should depend on the testing purpose and the requirements of the sample.

Main Functions

This type of tube is designed to collect human blood and is commonly used for routine blood tests, coagulation time checks, and some special examinations. Its working principle is based on vacuum negative pressure, which quickly draws blood into the tube without damaging the sample or affecting test results.

After collection, samples must be properly preserved to prevent bacterial contamination or environmental factors from causing inaccurate outcomes.

How to Use

1. Preparation before collection: Wash hands thoroughly and check whether the tube is intact.

2. Blood collection: Insert the vacuum tube into the holder, pierce the skin with a lancet or needle, and blood will automatically flow into the tube.

3. Serum separation: Gently rotate the tube so the blood spreads evenly along the wall. After standing for a few minutes, serum will naturally separate. Use a pipette to extract the serum.

4. Serum storage: Keep the serum at a low temperature. Bring it back to room temperature before testing.

Precautions

- Avoid shaking the tube during collection to prevent hemolysis.

- Minimize the use of preservatives to protect cell structure.

- Send samples for testing as soon as possible to avoid cell rupture.

- Keep the tube tightly sealed to prevent backflow or contamination.

- If the patient feels dizzy or faint, stop the procedure and resume only after recovery.

Conclusion

The disposable vacuum blood collection tube (plain type) is widely used in clinical laboratories due to its convenience and reliable results. To ensure accuracy, it is essential to follow proper procedures and maintain correct storage conditions. For professional advice or bulk procurement, it is recommended to contact certified medical device suppliers or specialized institutions.
