Abstract

The present disclosure relates to systems and methods for injecting multiple fluids into the vasculature of a patient using a minimal number of valve and stopcock manipulations. In particular, the present disclosure relates to a fluid injection system that combines a contrast source valve and a manifold in-line to a manual or automated syringe assembly for alternately injecting contrast and saline solutions into the vasculature of a patient.

First claim

What is claimed is:

1 . A manifold, comprising:
a housing that defines intersecting first, second, third and fourth ports, wherein the non-intersecting end of each port is configured to be fluidly connected to an element that includes a fluid channel; a rotatable stopcock comprising three fluidly connected conduits rotatably disposed at the intersection of the first, second, third and fourth ports; and an actuator attached to the rotatable stopcock.

2 . The manifold of claim 1 , wherein the non-intersecting end of the first port is fluidly connected to a pressurized saline source.

3 . The manifold of claim 1 , wherein the non-intersecting end of the second port is fluidly connected to a dual-check valve.

4 . The manifold of claim 1 , wherein the non-intersecting end of the third port is fluidly connected to a pressure transducer.

5 . The manifold of claim 1 , wherein the non-intersecting end of the fourth port is fluidly connected to a catheter.

6 . The manifold of claim 1 , wherein the rotatable stopcock is configured to rotate about four stopcock positions within the manifold.

7 . The manifold of claim 6 , wherein the rotatable stopcock is rotated by turning the actuator attached to the rotatable stopcock.

8 . The manifold of claim 6 , wherein each of the four stopcock positions blocks fluid communication with a different one of the first, second, third and fourth ports.

9 . The manifold of claim 8 , wherein a first stopcock position places the second, third and fourth ports in fluid communication and blocks fluid communication with the first port.

10 . The manifold of claim 8 , wherein a second stopcock position places the first, third and fourth ports in fluid communication and blocks fluid communication with the second port.

11 . The manifold of claim 8 , wherein a third stopcock position places the first, second and fourth ports in fluid communication and blocks fluid communication with the third port.

12 . The manifold of claim 8 , wherein a fourth stopcock position places the first, second and third ports in fluid communication and blocks fluid communication with the fourth port.

13 . A fluid injection system, comprising:
a syringe assembly; a contrast source valve fluidly connected to the syringe assembly; a manifold fluidly connected to the contrast source valve; and a catheter fluidly connected to the manifold.

14 . The fluid injection system of claim 13 , wherein the contrast source valve is a dual-check valve.

15 . The fluid injection system of claim 13 , wherein the contrast source valve is fluidly connected a contrast source.

16 . The fluid injection system of claim 13 , wherein the manifold comprises:
a housing that defines intersecting first, second, third and fourth ports, wherein the non-intersecting end of each port is configured to be fluidly connected to an element that includes a fluid channel; a rotatable stopcock comprising three fluidly connected conduits rotatably disposed at the intersection of the first, second, third and fourth ports; and an actuator attached to the rotatable stopcock.

17 . The fluid injection system of claim 16 , wherein the non-intersecting end of the first port is fluidly connected to a pressurized saline source.

18 . The fluid injection system of claim 16 , wherein the non-intersecting end of the second port is fluidly connected to the syringe assembly.

19 . The fluid injection system of claim 16 , wherein the non-intersecting end of the third port is fluidly connected to a pressure transducer.

20 . The fluid injection system of claim 16 , wherein the non-intersecting end of the fourth port is fluidly connected to the catheter.

21 . The fluid injection system of claim 13 , further comprising a utility port fluidly connected between the contrast source valve and the manifold.
