ABSTRACT:
A multifunctional safety infusion set with injection needle retractable in a wing-equipped sheath. The infusion set includes a connecting tube having an upper and a lower engaging sections respectively near top end and bottom end of the connecting tube. The bottom end of the connecting tube is connected with an infusion tube, while the top end thereof is connected with an injection needle. The infusion set further includes a wing-equipped sheath slidably fitted around the connecting tube. When the sheath is slid downward to engage with the lower engaging section of the connecting tube, the injection needle protrudes outside the sheath for injection. After the injection is completed, the sheath is slid upward to engage with the upper engaging section of the connecting tube so as to totally enclose and hide the injection needle in the sheath without protruding outside. Therefore, the accidental impalement of medical personnel is avoided and the safety is ensured.
