Action Principle And Dosage Of Silicifying Agent For Vacuum Blood Collection Tube

As a kind of high molecular organic silicon material, silicifying agent is often used in various vacuum test tubes because of its ideal silicification effect, so as to achieve smooth tube wall and avoid wall hanging. Since vacuum blood sampling is used in clinical medicine, it is required to pay attention to its usage, dosage and precautions after the preparation of silicified agent.

Water-soluble silicifying agent

1, Principle of action of silicification agent for blood sampling

The silicified agent is used on the inner wall of the blood collection tube, which can promote the tube to be free of burrs and smooth, effectively improve the separation of blood clots, and also prevent the occurrence of hanging blood. In addition, due to the silica powder contained in the composition, it has hydrophobic property and high dispersion after contacting with the blood sample, which is conducive to blood coagulation in a short time and improves the detection efficiency.

2, Usage and dosage of silicifying agent

As the silicifying agent is divided into water-soluble silicifying agent and oil silicon, the usage and dosage of the two silicifying agents are different.

Specific usage of silicone oil is as follows:

1. Take one part of the silicifying agent, add 100-200 parts of light petroleum under the boiling range of 60-90 ℃, the concentration of which is between 0.5-1.0%, and then fully stir evenly.

2. After the solution is stirred evenly, spray it into the test tube to make it adhere around the inner wall of the test tube, or immerse the test tube directly in the prepared solution for a short stay.

3. After adding, drain the glass tube mouth downward, place it at room temperature for about 2 hours, add other reagents after drying, or add it after drying at high temperature.

4. If it is a plastic test tube, it needs to be placed at room temperature for about 3 hours, and then add other reagents to the test tube after it is completely solidified.

Dosage and usage of water-soluble silicide:

1. Take 0.5-1 parts of the corresponding silicifying agent, and then add 100 parts of deionized water to prepare 0.5-1% water solution, and then fully mix.

2. Add the prepared solution into the test tube or soak it in the solution, and take it out after staying for a period of time.

3. Fully drain the prepared solution tube mouth downward, and then dry it in a 90-degree oven.

3, Precautions for use of silicifying agent

The silicifying agent should not contain impurities in the preparation process. During treatment and preparation, attention should be paid to keeping the test tube and preparation tools clean. It can be prepared directly with pure water, which is easy to operate. In addition, there are differences in technology and environment in the preparation process, so small batch experiments should be carried out before batch use.
