Patent number: 10322238Abstract: A needle-free injection device suitable for delivering a therapeutic substance into the intradermal space of a patient. The needle-free injection device includes an injector body defining a syringe end. The device also includes a first handle attached with a hinge to the injector body such that the first handle pivots between an open and a closed position and remains attached to the injector body during an injection, a main spring positioned within the injector body, a return sleeve engaged with the main spring, and a first linkage between the first handle and the return sleeve. The first linkage causes the return sleeve to move away from the syringe end of the injector body when the first handle is moved from the open position to the closed position, thereby compressing the main spring. Needle-free injection systems and methods of operating a needle-free injection device are also disclosed.Type: GrantFiled: July 10, 2017Date of Patent: June 18, 2019Assignee: PharmaJet, Inc.Inventors: Chris Cappello, Matt Wixey, John W.

Patent number: 10232110Abstract: A sealed fluid transfer device comprised of tubing, a proximal fitting, and a distal needle assembly is provided. The needle assembly includes a needle hub secured to a needle cannula. A cantilevered actuator arm extends outwardly from the needle hub having an actuator button at its free end. The needle assembly is disposed in a barrel and can move from a distal position, where the needle is exposed, to a proximal position, where the needle is shielded. The barrel includes a septum which seals the barrel. A spring is disposed in the barrel for propelling the needle assembly to the proximal position. The barrel includes an aperture that receives the actuator button for locking the spring in a compressed condition. Depression of the actuator button enables the spring to propel the needle assembly into its proximal position. A safety mechanism prevents inadvertent depression of the actuator button.Type: GrantFiled: July 8, 2014Date of Patent: March 19, 2019Assignee: Becton, Dickinson and CompanyInventors: S.
