How to Use a Disposable Capillary Blood Collection Container

1. Instructions for Use

A disposable capillary blood collection container is mainly used to collect small volumes of whole blood from capillary sites such as the fingertip. It is commonly applied in blood glucose testing, routine blood screening, and other point-of-care or primary healthcare settings. Following a standardized procedure helps improve test accuracy while reducing patient discomfort.
1. Before use, open the package and carefully check that the container is intact, clean, and free from damage or contamination.
2. Confirm the required blood volume according to the specific test. Capillary blood collection containers are designed for small-volume whole blood sampling.
3. Select an appropriate sampling site, such as the fingertip. Disinfect the area with an alcohol swab and allow the skin to dry naturally.
4. Gently press the sampling site to improve local blood circulation.
5. Stabilize the sampling area and insert the lancet at an angle of approximately 45 degrees. Control the puncture depth to avoid unnecessary tissue injury.
6. Connect the blood collection container to the lancet interface. Blood will flow naturally into the container until the required volume is reached.
7. After collection, gently twist and remove the container, taking care not to touch the blood inside.
8. Apply sterile cotton or gauze to the puncture site to stop bleeding. Light finger movement may help restore circulation.
9. Close the container securely and send the sample for testing as soon as possible. This product is for single use only and must be discarded after use.
2. Precautions

1. Always inspect the packaging before use. Replace the product immediately if the package is damaged, damp, or contaminated.
2. Avoid sampling from areas with redness, broken skin, or signs of infection.
3. Wash hands and wear disposable gloves before the procedure to maintain aseptic conditions.
4. Apply moderate force during puncture. Excessive depth may cause pain or tissue damage.
5. Prevent air from entering the container, as air bubbles may affect test accuracy.
6. After sampling, gently rotate the container to ensure proper mixing of blood with the anticoagulant.
7. If the collected blood volume is insufficient, select a new sampling site and repeat the procedure.
8. Dispose of all used materials according to medical waste management regulations.
3. Summary and Recommendations

The disposable capillary blood collection container is valued for its ease of use, minimal invasiveness, and high safety level. It is widely used in primary healthcare facilities and rapid testing environments. Standardized operation improves result reliability and helps reduce infection risks.
