Excessive vacuum in clinical operation of blood collection tube and solutions

After successful venipuncture, the amount of blood collected exceeds the rated amount. The reason analysis and solutions are as follows

1. During the blood collection process, the patient's position changes (for example, sitting to collect the vein, which is different from the conventional blood collection method)-correctly guide the blood collection position;

2. The patient is nervous, and the venous pressure increases, which increases the blood collection volume-to soothe the patient's mood;

3. System limitations-when the blood sampling environment temperature is low, the blood sampling volume will increase as the temperature decreases.
