Abstract
A manually retracted safety needle device is provided having a rigid wing structure to stabilize the safety needle against the body of a patient. The safety needle device includes an elongate housing having a hub movably mounted therein. A tissue penetrating needle extends distally from the hub and a fluid conveying tube extends proximally from the hub. The rigid wing structure extends substantially along the length of the elongate member and, in one embodiment, includes wings extending transversely to a longitudinal axis of the elongate member. The safety needle is also provided with various finger gripping structures to facilitate manipulation of the safety needle device relative to the patient.
