The present invention generally relates to fluid delivery devices. More particularly, the invention relates to fluid delivery devices that receive fluid from a pre-filled vial of fluid.
In the dispensing arts, fluid delivery assemblies are used for moving and for dispensing fluids. For example, a source of fluid is supplied to a fluid delivery assembly, and the fluid delivery assembly can be used to move or dispense the fluid in a desired manner. Fluid delivery assemblies are sometimes also referred to generally as applicators, especially when the fluid delivery assembly is used to apply the fluid to an object.
In some circumstances, the fluid to be moved or dispensed by a fluid delivery assembly is contained in a vial. The fluid must be removed from the vial before it can be moved or dispensed by the fluid delivery assembly. Removing fluid from a vial can require a fluid delivery assembly to be partially disassembled or its components disconnected. For example, in a fluid delivery assembly that includes a syringe coupled with fluid delivery components, the syringe is disconnected from the fluid delivery components in order to couple the syringe with the vial of fluid. The fluid is then withdrawn from the vial and directed into the syringe. The syringe is then uncoupled from the vial and recoupled with the fluid delivery components. Finally, the fluid is forced from the syringe into the fluid delivery components. Disconnecting and reconnecting a syringe increases the number of steps that must be performed as part of a fluid delivery operation.
Embodiments of the present invention are directed to fluid delivery assemblies for withdrawing biomaterial fluid from a vial and for dispensing the biomaterial fluid, fluid control devices for use in fluid delivery assemblies, and related methods.
According to one embodiment of the invention, a fluid delivery assembly is provided for withdrawing biomaterial fluid from a vial and for dispensing the biomaterial fluid. The fluid delivery assembly includes a fluid transfer device configured for receiving the biomaterial fluid from the vial and for subsequently dispensing the biomaterial fluid, and a fluid control device coupled with the fluid transfer device. The fluid control device includes a body adapted to be coupled for fluid communication with the vial, and having a first port coupled with the fluid transfer device, and a second port for dispensing the biomaterial fluid. The fluid control device further includes a valve member carried by the body, the valve member being moveable between a first position in which the biomaterial fluid may be received from the vial into the first port and the fluid transfer device and a second position in which the biomaterial fluid received in the fluid transfer device may be dispensed through the first and second ports.
According to another embodiment of the invention, a fluid control device is provided for use in a fluid delivery assembly configured for withdrawing biomaterial fluid from a vial and for dispensing the biomaterial fluid. The fluid delivery assembly further includes a fluid transfer device. The fluid control device includes a body adapted to be coupled for fluid communication with the vial, and having a first port configured for coupling with the fluid transfer device, and a second port for dispensing the biomaterial fluid. The fluid control device further includes a valve member carried by the body, the valve member being moveable between a first position in which the biomaterial fluid may be received from the vial into the first port and the fluid transfer device and a second position in which the biomaterial fluid received in the fluid transfer device may be dispensed through the first and second ports.
According to yet another embodiment of the invention, a method is provided for dispensing biomaterial fluid from a fluid delivery assembly comprising a fluid transfer device, a fluid control device coupled with the fluid transfer device and having a valve member and an outlet port. The method includes coupling a vial of biomaterial fluid to the fluid control device, moving the valve from a first position to a second position, and transferring the biomaterial fluid from the vial into the fluid transfer device. The method further includes moving the valve from the second position to the first position, and dispensing the biomaterial fluid from the fluid transfer device through the outlet port of the fluid control device.
