3. Raise the baby's feet to a position higher than his heart, choose a safe blood collection position according to the "Schematic Diagram of Infant Blood Collection", and align the blood collection port of the blood collection device vertically at the blood collection site.
4. When the flat end of the blood sampling port is in light contact with the skin, press the launch button to collect blood, and quickly move the blood sampling device to the blood collection site.
5. Gently wipe off the first drop of blood with dry sterile gauze.
6.1 Appropriate light pressure, use the blood sample collection tube to collect an appropriate amount of blood sample, after the blood collection, use dry sterile gauze to lightly press the incision to stop the bleeding and prevent hematoma.
6.2 Appropriate light pressure, drop the blood directly on the blood carrier card for sampling, and collect at least 3 blood spots in a row. After blood sampling, use dry sterile gauze to lightly press the incision to stop the bleeding and prevent hematoma.

Contraindication
