Patent number: 11975172Abstract: An engagement mechanism associated with a reciprocally movable piston of a fluid injector is configured for releasably engaging an engagement portion at a proximal end of a rolling diaphragm syringe having a flexible sidewall configured for rolling upon itself when acted upon by the piston. The engagement mechanism has a plurality of engagement elements reversibly and radially movable relative to the engagement portion of the syringe between a first position, where the plurality of engagement elements are disengaged from the engagement portion of the syringe, and a second position, where the plurality of engagement elements are engaged with the engagement portion of the syringe. The engagement mechanism further has a drive mechanism for moving the plurality of engagement elements between the first position and the second position.Type: GrantFiled: December 17, 2021Date of Patent: May 7, 2024Assignee: BAYER HEALTHCARE LLCInventors: Kevin Cowan, Michael Spohn, Adam Steege, Jessie Delgado, Keith Lipford, Chet Larrow, Mariano Mumpower, Danica Gordon

Publication number: 20240108803Abstract: A drug storage and dispensing system that includes a packaging unit and an injection device for pre-filled containers having a needle shield and containing a medication is disclosed. The drug storage and dispensing system of the present disclosure provides for drug administration while minimizing the space occupied by such containers in the cold chain. The packaging unit minimizes the risk of a needle-stick injury, as a healthcare worker does not have to manually remove the needle shield. The injection device provides a novel way of auto-disabling a container, such as a syringe, as a plunger rod is not engaged with the container until the container is actually used. The drug storage and dispensing system provides for a reduction in the number of steps required to perform an injection, and thus a productivity and efficiency gain in mass immunization campaigns.Type: ApplicationFiled: December 14, 2023Publication date: April 4, 2024Inventors: Justin Wright, Hervé Monchoix, Damien Maréchal, Amanda Black, Eric Schneider, Chet Larrow

Publication number: 20230158229Abstract: An engagement mechanism associated with a reciprocally movable piston of a fluid injector is configured for releasably engaging an engagement portion at a proximal end of a rolling diaphragm syringe having a flexible sidewall configured for rolling upon itself when acted upon by the piston. The engagement mechanism has a plurality of engagement elements reversibly and pivotally movable about a pivot pin relative to the engagement portion of the syringe between a first position, where the plurality of engagement elements are disengaged from the engagement portion of the syringe, and a second position, where the plurality of engagement elements are pivotally movable about the pivot pin in a radially inward direction to engage with the engagement portion of the syringe. The engagement mechanism further has a drive mechanism for moving the plurality of engagement elements between the first position and the second position.Type: ApplicationFiled: January 9, 2023Publication date: May 25, 2023Inventors: Kevin Cowan, Michael Spohn, Barry Tucker, James Dedig, Gregory Johnston, Michael McDermott, David Berry, Adam Steege, Keith Lipford, Chet Larrow, Mariano Mumpwer, Danica Gordon
