Is the puncture needle head the same as the injection needle

Puncture needle heads are different from injection needles. The former has a slightly larger inner diameter and is used to diagnose abscesses and discharge pus, while the latter is used for subcutaneous or intramuscular injection. It is recommended that no matter what kind of needle is used for injection or puncture, it is necessary to hold the puncture site for 5-10 minutes to avoid subcutaneous bleeding.
