Vacutainer Plain Tube, Making Blood Collection Simple and Fast

Vacutainer Plain Tubes play an important role in modern medicine. They simplify the blood collection process and ensure the stability and accuracy of samples. This article will delve into thestructure, function, and clinical applications of vacutainer plain tubes, showing how they make blood collection more efficient and safe.

The Basic Structure of Vacutainer Plain Tubes

Vacutainer Plain Tubes usually consist of two parts: the tube body and the cap. The tube body can be made of PET (Polyethylene Terephthalate) plastic or glass. These materials are not only lightweight but also have pressure resistance and chemical resistance, ensuring the safe preservation of blood samples after collection. Vacutainer Plain Tubes use vacuum technology, creating negative pressure inside the tube, allowing blood to flow automatically into the collection tube without the need for additional tools like syringes, greatly simplifying the blood collection process.

Depending on the usage requirements, the interior wall of vacutainer plain tubes may be coated with different additives, such as anticoagulants or other substances that stabilize blood components. These additives ensure the stability and integrity of the sample after collection. Vacutainer Plain Tubes connect to the human vein via a disposable blood collection needle, ensuring a safe and contamination-free blood collection process.

The Main Functions and Advantages of Vacutainer Plain Tubes

Vacutainer Plain Tubes are clinical testing devices mainly used for collecting blood samples. Their primary function is using the principle of negative pressure to make blood flow automatically into the tube, facilitating the collection and preservation of blood samples.

Vacutainer Plain Tubes are typically made of glass or plastic and contain a certain amount of anticoagulant and additives. Anticoagulants prevent blood from clotting, maintaining the liquid state of the blood, thus ensuring the accuracy of the collected blood samples. Additives can help stabilize blood components, preventing changes in blood samples during collection and transportation.

The use of vacutainer plain tubes is very simple. When collecting blood samples, medical personnel need only connect one end to the blood collection needle and insert the other end into the patient's vein or artery. Then, wait for the blood to automatically enter the tube. Once the blood enters the tube, the medical personnel can remove the blood collection needle and seal the tube to send the blood to the laboratory for testing.

One of the advantages of vacutainer plain tubes is that they reduce the risk of contamination and cross-infection. Because the blood automatically enters the tube through negative pressure, the medical personnel do not need to directly contact the blood, reducing the possibility of infection. Additionally, vacutainer plain tubes can reduce the oxidation and contamination of blood samples, maintaining the stability of blood samples.

In summary, vacutainer plain tubes are convenient, safe, and accurate clinical testing devices. Their primary function is to automatically collect blood samples using the principle of negative pressure and maintain the stability of the blood. Their use can reduce the risk of contamination and cross-infection, improving the accuracy of blood samples.
