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

providing communication between a cylinder assembly in a control room of an imaging facility and a console in said control room, said console comprising a user control device;

providing communication between a hydraulic motor in a patient room of said imaging facility and a peristaltic pump in said patient room;

providing communication between said cylinder assembly in said control room and said hydraulic motor in said patient room;

driving said cylinder assembly with a motor of said console;

providing a second fluid from said cylinder assembly under pressure;

driving said hydraulic motor with said second fluid that is fed through said hydraulic motor to cause said hydraulic motor to generate rotary forces;

driving said peristaltic pump with said rotary forces generated by said hydraulic motor; and

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

2. The method of claim 1, wherein said injecting of said first fluid is caused by rotation of a rotor of said peristaltic pump 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.

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

providing communication between a cylinder assembly in a control room of an imaging facility and a console in said control room, said console comprising a user control device;

providing communication between a hydraulic motor in a patient room of said imaging facility and a gear cartridge in said patient room;

providing communication between said cylinder assembly in said control room and said hydraulic motor in said patient room;

driving said cylinder assembly with a motor of said console;

providing a second fluid from said cylinder assembly under pressure;

driving said hydraulic motor with said second fluid that is fed through said hydraulic motor to cause said hydraulic motor to generate rotary forces;

driving said gear cartridge with said rotary forces generated by said hydraulic motor; and

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

4. The method of claim 3, wherein said injecting of said first fluid 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.

5. A system to inject a first fluid into a patient during a magnetic resonance imaging procedure, said system comprising:

a console in a control room of an imaging facility, said console comprising a user control device;

a cylinder assembly in said control room of said imaging facility, said cylinder assembly being in communication with said console;

a peristaltic pump in a patient room of said imaging facility; and

a hydraulic motor in said patient room of said imaging facility, said hydraulic motor being in communication with said cylinder assembly and said peristaltic pump,

wherein a motor of said console drives said cylinder assembly,

wherein said hydraulic motor is driven with a second fluid that is provided from said cylinder assembly under pressure,

wherein said second fluid is fed through said hydraulic motor to cause said hydraulic motor to generate rotary forces that drive said peristaltic pump, and

wherein said peristaltic pump injects said first fluid into said patient.

6. A system to inject a first fluid into a patient during a magnetic resonance imaging procedure, said system comprising:

a console in a control room of an imaging facility, said console comprising a user control device;

a cylinder assembly in said control room of said imaging facility, said cylinder assembly being in communication with said console;

a gear cartridge in a patient room of said imaging facility; and

a hydraulic motor in said patient room of said imaging facility, said hydraulic motor being in communication with said cylinder assembly and said gear cartridge,

wherein a motor of said console drives said cylinder assembly,

wherein said hydraulic motor is driven with a second fluid that is provided from said cylinder assembly under pressure,

wherein said second fluid is fed through said hydraulic motor to cause said hydraulic motor to generate rotary forces that drive said gear cartridge, and

wherein said gear cartridge injects said first fluid into said patient.
