Publication number: 20030163096Abstract: 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.Type: ApplicationFiled: December 4, 2002Publication date: August 28, 2003Applicant: Becton, Dickinson and CompanyInventors: Kirk D.

Publication number: 20020188256Abstract: An automatically shieldable blood collection set is provided. The blood collection set includes a needle assembly having a hub with inner and outer tubes. A needle cannula is fixedly attached to the inner tube. The outer tube is split longitudinal, and a first spring biases the slit into an open orientation. A safety shield is telescoped between the tubes to the hub and the needle cannula and can be moved from a proximal position where the needle cannula is exposed to a distal position where the needle cannula is safely shielded. A second spring is provided between the shield and the hub to propel the shield distally relative to the hub and into surrounding relationship with the needle cannula. However the outer tube can be biased against forces of the first spring to slit and clamp the shield in a fixed position.Type: ApplicationFiled: November 13, 2001Publication date: December 12, 2002Inventors: Jamieson William MacLean Crawford, Stefanie Livanos
