Abstract

Fluid injector systems used for a variety of imaging and injection procedures are disclosed. The systems may include separate modules or assemblies that may be located in different rooms of a hospital or imaging facility. Various single use and multiple use components may also be used with the modules or assemblies of the system. In addition, the injector system may include hydraulic and/or pneumatic fluid sources to power the system modules of the present invention.

Claims

1-14. -14. (canceled)

15. A method of injecting a first fluid into a patient during a magnetic resonance imaging procedure comprising:

providing a cylinder assembly in a control room of an imaging facility, wherein said cylinder assembly is in communication with an injector console;

providing a hydraulic motor and a peristaltic pump in a patient room of an imaging facility, wherein said hydraulic motor is in communication with said cylinder assembly and said peristaltic pump;

providing a second fluid in communication with said cylinder assembly and said hydraulic motor;

driving said cylinder assembly with a motor;

driving said hydraulic motor with said second fluid provided by said cylinder assembly;

driving said peristaltic pump with said hydraulic motor; and

injecting said patient with said first fluid using said peristaltic pump.

16. The method of claim 15 wherein said injecting is caused by rotation of a rotor of said peristaltic pumps which causes rollers of said rotor to compress a tubing, thereby drawing in said first fluid and transporting said first fluid through said tubing and into said patient.

17. A method of injecting a first fluid into a patient during a magnetic resonance imaging procedure comprising:

providing a cylinder assembly in a control room of an imaging facility, wherein said cylinder assembly is in communication with an injector console;

providing a hydraulic motor and a gear cartridge in a patient room of an imaging facility, wherein said hydraulic motor is in communication with said cylinder assembly and said gear cartridge;

providing a second fluid in communication with said cylinder assembly and said hydraulic motor;

driving said cylinder assembly with a motor;

driving said hydraulic motor with said second fluid provided by said cylinder assembly;

driving said gear cartridge with said hydraulic motor; and

injecting said patient with said first fluid using said gear cartridge.

18. The method of claim 17 wherein said injecting is caused by rotation of a rotor which causes gears in said gear cartridge to rotate and compress a tubing located between said gears, thereby drawing in said first fluid and transporting said first fluid through said tubing and into said patient.
