1. A needle protective sheath, comprising:
- a top wall, a bottom wall, and a pair of side walls joining the top and bottom walls,the walls defining a front opening and a rear opening at opposite ends of the sheath,each side wall having a slot therein extending from the front opening to a point displaced from the rear opening, each slot being constructed to receive a wing extending from a hub of a butterfly needle as the needle is retracted into the needle protective sheath through the front opening, anda finger shield extending from the top wall at the front opening,the finger shield being attached to the top wall by a hinge portion,the finger shield being constructed to rotate about the hinge portion, whereinthe finger shield is configured to block the front opening when the finger shield is rotated about the hinge portion from an open position to a closed position so as to secure the butterfly needle within the sheath when the finger shield is in the closed position,the finger shield is configured to remain secured in the closed position after it is rotated about the hinge portion into the closed position, andthe finger shield includes a first portion having a first width measured in a direction perpendicular to a longitudinal axis of the sheath that fits into the front opening, a second portion having a second width measured in said direction greater than the first width, and the second width not fitting into the front opening when the finger shield is in the closed position.

Abstract
Methods and devices for use and handling of intravenous and/or subcutaneous needles, and, more particularly, to safety devices for shielding needles or other sharp articles or devices that present a safety hazard are disclosed. In an embodiment, a needle protective sheath can include a top wall, a bottom wall, and a pair of side walls joining the top and bottom walls. A finger shield extends from the top wall at a front opening of the sheath and is attached to the top wall by a hinge portion. The finger shield can be rotated about the hinge portion to block the front opening so as to secure a needle within the sheath.
