Patent number: 10349880Abstract: A needle assembly is disclosed. The needle assembly includes a housing having a flash chamber, and having a distal end and a proximal end engageable with a specimen collection container. The assembly includes a cannula having a patient end, a non-patient end, and a sidewall extending therebetween defining a cannula interior. The patient end of the cannula projects at least partially from the distal end of the housing, and the cannula interior is in fluid communication with the flash chamber. The assembly further includes a shield restrainably engaged with a portion of the housing and axially transitionable over the patient cannula from a retracted position in which the patient end is exposed, to an extended position in which the patient end is shielded by at least a portion of the shield, wherein at least a portion of the flash chamber is visible in the retracted position.Type: GrantFiled: January 20, 2016Date of Patent: July 16, 2019Assignee: Becton, Dickinson and CompanyInventors: Jamieson Crawford, Robert Ellis, Bradley M. Wilkinson, Benjamin Bartfeld, C. Mark Newby, Chee Leong Alvin Tan, Jon Moh, Stanley Sim, Neville Yu Leng Chia

Patent number: 8888713Abstract: A blood collection assembly includes a housing and a cannula extending distally from the housing including a patient end, and a cannula shield removably engaged with a portion of the housing. The cannula shield is capable of shielding at least the patient end of the cannula, and includes a safety shield engagement. The assembly includes a pivoting safety shield engaged with a portion of the housing, which is transitionable from a retracted position in which the patient end of the cannula is exposed, to an extended position in which the patient end of the cannula is shielded by at least a portion of the safety shield. The safety shield includes at least one locking tab releasably engageable with the safety shield engagement, wherein the locking tab is fixedly engageable with a portion of the housing in the extended position.Type: GrantFiled: September 8, 2008Date of Patent: November 18, 2014Assignee: Becton, Dickinson and CompanyInventors: Jamieson Crawford, Robert Ellis, Bradley M.

Patent number: 8795198Abstract: A needle assembly includes a transparent or translucent housing with a fluid inlet end, a fluid outlet end, a flashback chamber, and a venting mechanism therebetween. Substantially axially aligned inlet and outlet cannulas extend from the housing and communicate with the chamber. A sealable sleeve covers the external end of the outlet cannula. Relative volumes of the cannulas, the chamber, and the sleeve are selected to provide rapid reliable flashback indicative of venous entry with an internal vent positioned within the housing so as to divide the interior into first and second chambers, with the second chamber being adapted to maintain a negative pressure therein relative to the external environment so as to inhibit leakage of blood from the needle on withdrawal from the patient.Type: GrantFiled: September 8, 2008Date of Patent: August 5, 2014Assignee: Becton, Dickinson and CompanyInventors: Chee Leong Alvin Tan, Jon Moh, Stanley Sim
