ABSTRACT:
A needle protector sheath comprises a body having a top wall, sidewalls and open ends. A slot is formed in each sidewall to slidingly receive a needle wing extending through each of the slots. Typically the slots extend through one end of the protector sheath. The protector sheath also defines an open, bottom aperture extending from end to end of the body, to permit the sheath to be laterally applied to tubing connected to a winged needle and to be advanced to a position where the needle tip is recessed in the sheath and the needle wings extend through the slots. In another embodiment an elongated anchor member may extend forwardly from the body to be manually pressed to retain the protector sheath as the needle is being withdrawn from the skin of a patient. The anchor member may have an outer end portion that bends away from the patient in position of use. Also, a novel sheath design and slot arrangement is disclosed.
