Patent number: 10279121Abstract: A mixing device and a retractable syringe comprising same are provided. The mixing device comprises concentric outer and inner barrels that form an outer chamber, the inner barrel having an inner chamber. A mixing plunger is slidably located in the outer chamber. A seal located in the outer chamber is capable of axial movement, in response to depression of the mixing plunger, from a first position in sealing engagement with one or more apertures in the inner barrel to a second position intermediate the apertures and vents in the outer barrel. This allows depression of the mixing plunger to force a first substance from the outer chamber through the apertures to mix with a second substance in the inner chamber. The mixed substance in the inner barrel is then delivered by the syringe with subsequent needle retraction.Type: GrantFiled: October 22, 2015Date of Patent: May 7, 2019Assignee: UNL Holdings LLCInventors: Ramin Mojdehbakhsh, Peter J. Dungar, Ashley W. Palmer, Robert E. Johannesson, Philip A. Weaver, Aaron M. Weir

Patent number: 9757527Abstract: Barrel adapters for safety syringes include a barrel and a plunger assembly adapted to move within the barrel, a barrel tip adapted to be sealingly engaged with a distal end of the barrel and a needle retraction mechanism barrel having a needle subassembly and an actuator subassembly. The needle subassembly includes a needle, and a needle-over-mold (NOM) through which the needle extends. The needle subassembly is disposed at least partially within the barrel tip, and adapted to move from an injection position in which the needle extends from a distal end of the barrel tip to a retracted position in which the needle is disposed within at least one of the barrel tip or the barrel. The actuator subassembly includes a needle seal, a push-bar, and an actuator surface. The needle retraction mechanism barrel includes a biasing member and an actuable locking arrangement. A syringe includes such barrel adapters.Type: GrantFiled: March 2, 2015Date of Patent: September 12, 2017Assignee: UNL Holdings LLCInventors: Kevin L. Bokelman, Eduardo Ho, Robert Scott Russo, Brandon J. McKee, John W. Carosi, Christian P. Brandt, Jyoti Gupta, Ramin Mojdehbakhsh
