Disposable Vacuum Blood Collection Container Light Green Blood Collecting Vessel

Classification and Application

Light green blood collecting vessel plasma separating tube

Contains heparin lithium or heparin sodium and gel. Heparin is a kind of mucopolysaccharide containing sulfuric acid group and has a strong negative charge. It has the effect of strengthening antithrombin 3 to inactivate serine protease, thereby preventing the formation of thrombin , And has a variety of anticoagulant effects such as preventing platelet aggregation, usually 15IU heparin anticoagulant 1ml blood. Heparin tubes are generally used for emergency biochemical and blood rheological testing.
Sample type: plasma
Uses: TNT, environmental protection mycin, B27, blood ammonia, BNP (B-type natriuretic peptide)

Structure Composition

The disposable vacuum blood collection container consists of a test tube, a plug, a cap, a label, additives (if any) and additives (if any).

Scope Of Application

Used in conjunction with disposable intravenous needles for the collection, transportation and preservation of human venous blood.

Storage Requirements

Store in a dry, well-ventilated and clean room with no corrosive gas and relative humidity above 80%

Precautions During Use

1 According to different inspection requirements, select the appropriate blood collection tube. If you have any questions, please feel free to contact the staff of the laboratory.

2 The sample number must be pasted on the blood collection tube, which is consistent with the number on the inspection sheet. It should be pasted on the paper label of the blood collection tube, not on the glass to prevent it from falling off.

3 When taking blood, the patient should relax and the environment should be warm to prevent venous contracture. The tourniquet time should not be too long (now some scholars think that the tourniquet should not be used as much as possible), observe whether the blood collection is smooth, and it is forbidden to pat the arm, otherwise it may cause local blood concentration or Activate the coagulation system.

4 The recommended blood collection sequence is non-anticoagulant tube (serum tube) → separating gel/coagulant tube → heparin/EDTA tube → coagulation tube → erythrocyte sedimentation tube. The main reason is that the first tube often contains tissue fluid, which is easy to cause coagulation, which is not suitable for blood coagulation determination; furthermore, to avoid contamination of the serum tube with anticoagulants.

5 After the blood collection is completed, according to different test categories (biochemical, immune, routine, coagulation, erythrocyte sedimentation rate), use the test sheet to roll up the blood samples and divide them into categories. All blood samples should not be mixed together to avoid confusion in operation.

6 The ratio of blood to anticoagulant must be accurate, and the amount of blood collected should meet the requirements.

7 After blood collection, gently invert the test tube to mix 8-10 times, but do not shake it violently. After blood collection, the sample should be placed vertically.
