A butterfly needle assembly has a needle and a shield with wings integral to either the needle or the shield. The wings have aesthetically pleasing patterns to distract the patient during treatment. The mechanical design of the needle and shield juncture improves the stability of the assembly when inserted into a patient, as well as allowing the assembly to be disengaged with a single hand to help the caregiver avoid a needle "stick" and prevent the spread of diseases.
