The problems needing attention in blood collection include: blood collection site, patient's body position during blood collection, the influence of tourniquet, the influence of infusion, and the influence of the type and amount of anticoagulant.

1. Blood collection site

Blood samples collected from different blood collection sites will detect different results. For the same patient and the same project, it is unreasonable to collect blood samples from fingers today and veins tomorrow. Blood samples collected from fingers and veins of the same patient are used for blood routine, and the results are different.

2. Effect of tourniquet

When the tourniquet was pressed for 40 seconds, the total protein increased by 4% and aspartate transferase (AST) increased by 16%; After more than 3 minutes, local blood concentration, serum iron, serum calcium, acid phosphatase (ACP) and blood potassium increased, lactic acid increased and pH value decreased.

3. Patient position

The test results of samples collected by nurses are different when patients are in different positions of lying position, sitting position and standing position. Compared with lying position, the total amount of plasma in normal people in standing position decreased by about 12%, resulting in changes in erythrocyte (HB), leukocyte (WBC), erythrocyte (RBC), hematocrit (HCT), lipids and proteins. Prolonged hemostasis will cause changes in the coagulation system, and repeated fist clenching will increase blood potassium

Safety Blood Sample Needle Holder：When drawing blood, the test tubes should be reasonably arranged in order to achieve safe and accurate results. Vacuum blood collection vessel is a disposable negative pressure vacuum glass tube which can realize quantitative blood collection. It needs to be used together with venous blood collection needle. Under the action of negative pressure, human venous blood is pumped into the vacuum tube through the blood collection needle. Such a venipuncture can realize multi tube collection without leakage. For multi tube blood collection, color marking and sorting shall be carried out for the blood extraction vessels to prevent confusion and errors. You can also sort by labeling. The general color codes are sorted as follows: 1 Common serum tube red cap. 2. Rapid serum tube orange cap. 3. Golden head cover of inert separation gel accelerating tube. 4. Black cap of sodium citrate ESR test tube. 5. Sodium citrate coagulation test tube light blue cap. 6. Heparin anticoagulant tube green cap. 7. Light green head cover of plasma separation tube. 8. Potassium oxalate / sodium fluoride gray cap. 9. Purple head cover of EDTA anticoagulant tube.
