A syringe assembly comprising a barrel for containing one or more medicaments, the barrel having a front outlet for allowing the expulsion of said one or more medicaments from the said barrel through said outlet, and a first stopper disposed in the barrel and axially moveable therein and defining a first volume in the barrel axially forwards of the first stopper and a second volume in the barrel axially rearwards of the first stopper. The first stopper has a two way valve that is moveable between a sealing configuration and an open configuration to selectively put the first volume in fluid communication with the second volume. The two way valve is moveable from the sealing configuration to the open configuration by an increase in fluid pressure in either of the first and second volumes. The syringe assembly additionally comprises a second stopper disposed in the barrel axially rearward of the first stopper and axially moveable therein, the second stopper providing a fluid tight seal at a rear end of the second volume. The syringe assembly further comprises a first plunger rod connected to the first stopper and extending axially rearwardly through the second stopper, the second stopper sealingly engaging with the first plunger rod but permitting axial sliding of the first plunger rod therethrough. The first plunger rod is axially moveable so as to axially move the first stopper and pressurise either of the first volume and second volume causing the two way valve to move into the open configuration and fluidly connect the first volume and second volume.

Mixing syringe assembly

A valved container assembly has a container for containing a fluid, extending in an axial direction, and having an open front end and a valve disposed in the container. A plunger element is disposed axially rearward of the valve and is axially moveable in the container. The plunger element is configured to increase the pressure of a fluid in a first volume of the container upon axial movement of the plunger element relative to the valve. The valve includes a channel bypassing a seal, the channel having a first opening in fluid communication with the atmosphere outside of the valved container assembly and a second opening selectively sealed from the first volume by a resilient seal. The resilient seal is moveable from a sealing configuration to an open configuration upon the pressure of the fluid in the first volume exceeding a first pressure threshold.

Valved container assembly

A valved container assembly () comprising a container () for containing a fluid, the container () extending in an axial direction and having at least one venting opening () at a front end and at least one dispensing opening (). The valved container assembly () further comprising a valve () disposed in the container () and a plunger element () disposed axially rearward of the valve (), the plunger element () being axially moveable in the container () and defining a first volume () in the container () between the plunger element () and the valve (), where the plunger element () is configured to increase the pressure of a fluid in the first volume () upon axial movement relative to the valve (). The valve () comprises a permanent seal () forming a fluidic seal between the at least one venting opening () and the first volume (), and a resilient seal () that is axially rearward of said permanent seal () and is moveable between a sealing configuration and an open configuration. In the sealing configuration the resilient seal () forms a fluidic seal with the container () between the at least one dispensing opening () and the first volume (). In at least one axial position of the valve () in the container () when the resilient seal () is in the open configuration the first volume () is fluidly connected to the at least one dispensing opening (). The resilient seal () is moveable from the sealing configuration to the open configuration upon fluid pressure in the first volume () exceeding a predetermined pressure threshold.

A syringe assembly having a barrel for containing one or more medicaments and a stopper disposed in the barrel defining and separating a first volume and a second volume within the syringe assembly. The stopper includes a permanent seal fluidly sealing the stopper to the barrel about the entire perimeter of the stopper intermediate the first volume and second volume, and a channel bypassing the permanent seal, the channel having a first opening in fluid communication with the second volume and a second opening selectively sealed from the first volume by a resilient seal. The resilient seal is moveable between a sealing configuration and an open configuration to selectively seal the channel from the first volume and is moveable from the sealing configuration to the open configuration upon fluid pressure in the first volume or second volume exceeding a first pressure threshold.

Syringe assembly

A valved container assembly which has a container for containing a fluid, the container extending in an axial direction and having an open front end and a valve disposed in the container. The valved container assembly is configured so that forward axial movement of the valve relative to the container is inhibited. A plunger element is disposed axially rearward of the valve and is axially moveable in the container. The plunger element is configured to increase the pressure of a fluid in a first volume of the container upon forward axial movement relative to the valve. The valve includes a channel bypassing the permanent seal, the channel having a first opening in fluid communication with the atmosphere outside of the valved container assembly and a second opening selectively sealed from the first volume by a resilient seal.
