Common faults and elimination methods of clinical operation of vacuum blood collection tube
Common faults and troubleshooting methods in clinical operations
1. Blood reflux, preventive measures
1. Place the patient's arm at a lower position;
2. Hold the test tube with the plug facing up;
3. Release the tourniquet when blood begins to flow into the test tube.
Second, the blood collection speed is slow, the reason analysis and solution
1. For patients with high blood viscosity, choose a small model-choose a suitable blood collection needle;
2. Did not choose median elbow vein or precious vein during puncture-when collecting blood samples from multiple tubes, be sure to choose median elbow vein or precious vein.
3. The limitation of blood collection tube system. The blood collection with small ml size is slower than the blood collection with large ml size, and the blood collection with small needle is slower than that with large needle.
