发明名称 Prick resistant medical needle for intravenous injections
摘要 A medical intravenous injection needle which resists accidental skin pricks is disclosed. The needle tip is designed to be sharp enough to easily puncture medication bottle membranes and intravenous tubing but resists puncturing the skin. Illustratively, the tip has a flattened or rounded edge to provide the appropriate penetration ability.
