What are the common problems and solutions when using vacuum blood collection tubes?

Vacuum blood collection is a common tool used in clinical practice to collect blood samples. During use, you may encounter some common problems that need to be resolved in a timely manner. This article will introduce common problems and corresponding solutions when using vacuum blood collection tubes from different perspectives.

Preoperative preparation questions:

1. Damaged blood collection vessel: Sometimes, the blood collection vessel may be damaged during transportation, and the outer packaging may be scratched or the gas chamber may be damaged. In this case, we should immediately replace a intact blood collection tube to avoid contamination and loss of blood samples.

2. Temperature issue: In clinical practice, blood vessels need to be kept within an appropriate temperature range during transportation and storage. If blood vessels are placed in high or low temperature environments, it may cause the blood sample to lose activity or coagulate. We should properly store and protect the blood collection tube to ensure that it is under appropriate temperature conditions.

Operational process issues:

3. No air is left during blood collection: When preparing to collect blood, we need to connect the blood collection device to the blood vessel according to the instructions to ensure that blood can flow freely into the collection vessel. If appropriate operational steps are not taken, it may result in air remaining in the blood collection vessel. In this case, we should slightly raise the blood collection device and gently tap the tube wall to raise the air to the top, then carefully discharge it.

4. Slow blood collection speed: Sometimes, the blood collection speed may be slow, possibly due to blocked blood vessels or poor connection between the blood collection vessel and the needle. We should check for these issues and promptly resolve them.

5. Detachment of the blood collection vessel from the needle: During the blood collection process, if the connection between the blood collection vessel and the needle is not firm, it may cause the blood collection vessel to detach from the needle, causing blood to leak out. At this point, we should immediately replace the blood collection tube with a new one and ensure that the connection is secure.

Sample processing issues:

6. Delayed coagulation: When blood samples cannot coagulate in a timely manner after collection, it may be due to some reason. In this case, we should place the blood collection tube at appropriate temperature and conditions as soon as possible to promote the occurrence of coagulation.

7. Blood clots: Sometimes, blood clots may occur during sample processing. At this point, we should carefully shake the blood collection tube to help dissolve the clot and take corresponding steps for treatment.

Other issues:

8. Expiration of blood collection tubes: Each blood collection tube has its expiration date and should be immediately discontinued after expiration to avoid affecting the accuracy of blood analysis results. We should regularly check and replace expired blood collection tubes.

9. Incorrect selection of blood collection vessels: Based on different experimental requirements and blood collection purposes, we need to choose an appropriate blood collection vessel. If the selection is incorrect, it may affect the accuracy of the experimental results. Therefore, we should carefully read and understand the specifications and uses of blood collection vessels, and make the right choice.

The above are some common problems and solutions that may be encountered when using vacuum blood collection tubes. In the process of using blood collection vessels, we should strictly follow the operating procedures, promptly identify and solve problems, and ensure the safety of the blood collection process and the quality of blood samples.
