Abstract
A system for use in delivery of precise, small volumes of medical fluid to a patient is described. The system includes a first tubing set having a first length of tubing and a second length of tubing, a first connector member positioned at the proximal end of the first length of tubing configured to connect to a syringe, and a valve assembly positioned at the distal end of the first length of tubing. The system utilizes a section of the first length of tubing to measure and contain the small volumes of medical fluid for flushing into a patient through the valve assembly and second length of tubing.
Claims24
A system for use in delivery of fluid to a patient, the system comprising:
- a first tubing set having a first length of tubing and a second length of tubing, the first length of tubing and the second length of tubing each having a proximal end and a distal end;
- a first connector member positioned at the proximal end of the first length of tubing, the first connector member configured to connect to a flushing syringe;
- and
- a valve assembly positioned at the distal end of the first length of tubing, the valve assembly comprising:
- a proximal port, a distal port, and a third port;
- a second connector member connecting the distal end of the first length of tubing to the proximal port;
- a third connector member connected to the distal port;
- and
- a fourth connector member connecting a first swabable valve and the second length of tubing to the third port,
- wherein a container containing a medical fluid is removably connected to the first swabable valve, and
- wherein the valve assembly selectively provides a fluid connection between the proximal port, the distal port, and the third port.

A method of using a fluid injection system, the method comprising:
- providing a fluid injection system comprising:
- a housing, at least one syringe, at least one drive member, and at least one controller programmed or configured to actuate the at least one drive member;
- an administration line;
- a first length of tubing having a proximal end and a distal end;
- a first connector member positioned at the proximal end of the first length of tubing, the first connector member configured to connect to the at least one syringe;
- and
- a valve assembly positioned at the distal end of the first length of tubing, the valve assembly comprising:
- a proximal port, a distal port, and a third port;
- a second connector member connecting the distal end of the first length of tubing to the proximal port;
- a third connector member connected to the distal port and configured to connect to a proximal end of the administration line;
- and
- a fourth connector member connecting a first swabable valve to the third port;
- priming the at least one syringe by pushing a flushing fluid into the at least one syringe;
- connecting the administration line to the third connector member and the proximal port of the valve assembly;
- connecting the proximal end of the first length of tubing to the at least one syringe of the fluid injection system;
- priming the fluid injection system by actuating the at least one drive member and pushing a flushing fluid contained in the at least one syringe through the first length of tubing and through the administration line;
- connecting a container containing a medical fluid to the first swabable valve;
- actuating the at least one drive member to draw a volume of the medical fluid into the first length of tubing;
- and
- actuating the at least one drive member to push the volume of medical fluid from the first length of tubing through the administration line and to the patient.
