Treatment Process Of Silicified Agent For Venous Blood Collection Tubes

The use of vacuum blood collection tube for blood collection is a major change compared with the previous blood collection method. Because it completes a series of operations of blood collection without contact with external interference, it fundamentally eliminates the possibility of contamination, and is convenient and fast, which is very popular with hospitals. However, due to the large number of manufacturers producing vacuum blood collection, the poor quality of products has become a major problem, especially the silicification treatment of blood collection, which is the basis of blood collection and analysis, and can directly affect the test results. So we will focus on how to treat the silicified agent.

Water-soluble silicifying agent

1, Silicification treatment

The silicifying agent is hydrolyzed into a colorless transparent or yellow liquid, and then a special catalyst is added to the liquid to prepare a solution of a certain concentration, which is coated in a test tube made of plastic or glass. Under certain conditions, the silicifying agent can form a dense protective film in the test tube to improve the performance of the test tube.

2, Principle and function of silicification

The silicifying agent is mainly divided into water-based silicifying agent and oil silicon, with different compositions. The oil silicon is a high molecular organic silicon material, and the water silicon is a high molecular methyl polyoxane copolymer. They not only have hardness and wear resistance, but also have the adhesion and flexibility of polymers. At the same time, their light transmittance is also very high. Therefore, they are very suitable for the wear-resistant and anti-scratch treatment of the surface of test tubes.

In addition, although these two kinds of silicides are applicable to the treatment of the inner wall of blood vessels, it is not easy to have good physiological inertia, so most manufacturers have high requirements for the spraying process. If the silicification treatment achieves the effect, the inner wall will be very smooth. Generally, it can be identified through a simple water pouring experiment. The inner wall of the silicified test tube is free of water droplets, so there will be no wall hanging phenomenon during the blood sample detection.

3, Process flow of silicifying agent treatment

Both water silicon and oil silicon will be treated and added before being added to the test tube, not directly after purchase. In the oil silicon treatment process, the silicifying agent will be taken first, and then light petroleum will be added to stir and mix, and the mixed solution will be sprayed into the test tube in any way, such as dip coating, spray coating, spin coating, etc. After curing, it can be used after drying at high temperature. The silicon water treatment process is prepared with deionized water, fully mixed and then sprayed into the test tube, and placed in the oven for drying.
