Shieldable fluid collection set

摘要

A fluid collection or infusion set is provided with a needle assembly that is slidably disposed in a generally tubular shield. The needle assembly includes two opposed flexible wings that are slidably receivable in at least one slot of the shield. The wings can be rotated from a coplanar disposition into a position where the wings are in face-to-face engagement with one another. A flexible bridge may extend between the wings to facilitate manipulation of the needle assembly. The shield may be tapered to wider dimensions closer to the proximal end of the shield. The wings may include lugs that engage external surfaces of the shield and cause the wings to stretch as the shield is moved distally over the needle assembly. The lugs then snap into recesses at the proximal end of the shield or preventing re-exposure of the needle. Alternatively, the shield may include a locking clip that can be rotated into a position for covering portions of the slot in the shield to prevent re-exposure of the needle.
