BULK FLUID SOURCE INJECTOR SYSTEMS
An injector system including a docking station and a cassette and various transfer devices for transferring fluid from a bulk fluid container to a reservoir in the cassette are described herein along with methods for using such devices and systems to inject fluid from the bulk fluid container into a patient.
1 . A transfer device comprising:
a spike;
a port connector;
a transfer tube operably connected to the spike and the port connector; and
a guard enclosing the spike, port connector and transfer tube.
2 . The transfer device of claim 1 , further comprising an air vent and a vent tube or secondary passage aligned with the spike.
3 . The transfer device of claim 2 , further comprising a check valve, air filter, or combination thereof operably connected to the air vent.
4 . The transfer device of claim 1 , wherein the port connector is retractable an operably connected to a spring.
5 . The transfer device of claim 4 , wherein the retractable port connector block flow of fluid through the transfer tube when in extended position.
6 . The transfer device of claim 4 , further comprising a first transfer tube operably connected to the spike and a second transfer tube enclosed within the port connector.
7 . The transfer device of claim 1 , further comprising a septum disposed over a distal portion of the transfer tube.
8 . A cassette for transporting fluid from a source to a patient comprising:
a cassette body;
one or more reservoirs dispose within the cassette body;
at least one inlet port operably connected to each of the one or more reservoirs;
at least one fluid passage operably connected to each of the one or more reservoirs; and
an outlet port at a convergence of at least one fluid passage.
9 . The cassette of claim 8 , further comprising at least one air vent operably connected to each of the one or more reservoirs.
10 . The cassette of claim 8 , further including a waste reservoir.
11 . The cassette of claim 8 , further comprising a fluid detector operably connected to at least one of the one or more reservoirs.
12 . The cassette of claim 8 , further comprising a pumping unit disposed within the cassette body.
13 . The cassette of claim 8 , further comprising as air detector operably connected to the outlet port.
14 . An injector system comprising:
a docking station, the docking station at least comprising a means for holding one or more bulk fluid containers; and
a cassette configured to be removeably connected to the docking station, the cassette comprising:
a cassette body;
one or more reservoirs dispose within the cassette body;
at least one inlet port operably connected to each of the one or more reservoirs;
at least one fluid passage operably connected to each of the one or more reservoirs; and
an outlet port at a convergence of at least one fluid passage.
15 . The injector system of claim 13 , further comprising a transfer device configured to operably connect at least one bulk fluid container held by the docking station to the at least one inlet port of the cassette.
16 . The injector system of claim 14 , wherein the transfer device comprises:
a spike;
a port connector;
a transfer tube operably connected to the spike and the port connector; and
a guard enclosing the spike, port connector and transfer tube.
17 . The injector system of claim 13 , wherein the docking station further comprises graphical user interface or monitor and a control system.
18 . The injector system of claim 16 , wherein the cassette further comprises a pumping unit and the docking station further comprises a drive motor operably connected to the control system, the drive system being configured to be operably connected to the pumping unit.
19 . The injector system of claim 16 , wherein the docking station further comprises one or more sensors operably connected to the control system.
20 . The injection system of 13 , further comprising a heater.
