How to Use a Disposable Capillary Blood Collection Container

A disposable capillary blood collection container is designed for collecting small volumes of whole blood from capillary sites such as the fingertip. It is widely used in blood glucose testing, routine blood screening, and other point-of-care diagnostic applications. Proper handling helps ensure accurate test results while reducing patient discomfort.

Usage Instructions
1. Open the package of the disposable capillary blood collection container and carefully check that the product is intact, undamaged, and free from contamination.
2. Confirm the required blood volume according to the specific test. Capillary blood collection containers are generally intended for small-volume whole blood sampling.
3. Select an appropriate sampling site, such as the fingertip. Clean the area with an alcohol swab and allow the skin to air-dry naturally.
4. Gently press or massage the sampling area to promote local blood flow.
5. Stabilize the sampling site 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. Once collection is complete, 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. Seal the container securely and send the sample for testing as soon as possible. This product is for single use only and must be discarded immediately after use.
Precautions
1. Always inspect the packaging before use. Replace the product immediately if the package is damaged or contaminated.
2. Avoid sampling from areas with swelling, wounds, 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 injury.
5. Prevent air from entering the container, as air bubbles may affect test results.
6. After collection, gently rotate the container to ensure proper mixing of blood with any anticoagulant, if present.
7. If the collected blood volume is insufficient, select a new site and repeat the procedure.
8. Dispose of all used materials in accordance with medical waste regulations to prevent cross-contamination.
Summary and Recommendations
The disposable capillary blood collection container is valued for its ease of use, minimal invasiveness, and high safety level. It is particularly suitable for primary healthcare settings and rapid diagnostic testing.
Standardized use helps improve result reliability and reduces infection risks.
