Abstract

The fluid injection apparatus for use with a syringe includes an injector and a pressure jacket assembly associated with the injector. The injector includes a housing defining a central opening and a drive piston extendable through the central opening for imparting motive forces to a syringe plunger disposed within the syringe. The pressure jacket assembly includes a pressure jacket and at least one support arm associated with and extending outward from the housing. A syringe retaining member is attached to the at least one support arm. The syringe-retaining member defines a syringe receiving slot for receiving at least a portion of the syringe. A light source is located on the support arm and faces the pressure jacket for illuminating the syringe.

Claims

1. A fluid injection apparatus for use with a syringe, the fluid injection apparatus comprising:

a housing; and

a pressure jacket assembly associated with the housing for securing the syringe during an injection procedure, the pressure jacket assembly comprising;

a pressure jacket associated with the housing;

at least one pivotable support arm extending outward from the housing; and

at least one light source positioned along a length of the at least one support arm so that when the at least one support arm is positioned parallel to a central lateral axis of the syringe the light source is able to illuminate the syringe received in the pressure jacket by first emitting light through a wall of the pressure jacket.

2. The fluid injection apparatus of claim 1, wherein the light source is selected from the group consisting of light emitting diodes, a mini-fluorescent light bar, and a fiber-optic bed.

3. The fluid injection apparatus of claim 1, wherein the at least one support arm comprises a pair of support arms, and wherein at least one of the support arms comprises the at least one light source.

4. The fluid injection apparatus of claim 3, wherein the support arms are movable between a first position extending laterally along longitudinal sides of the pressure jacket and a second position depending below the pressure jacket, such that in the first position of the support arms the syringe is illuminated substantially along the central lateral axis.

5. The fluid injection apparatus of claim 3, wherein the at least one light source is selected from the group consisting of a plurality of light emitting diodes, a mini-florescent bar, and a fiber-optic bed.

6. The fluid injection apparatus of claim 1, further comprising a light-diffusing device associated with the pressure jacket for diffusing light passing through the wall of the pressure jacket.

7. The fluid injection apparatus of claim 6, wherein the light-diffusing device is associated with an inner surface or an outer surface of the pressure jacket.

8. The fluid injection apparatus of claim 6, wherein the light-diffusing device is disposed between an inner surface and an outer surface of the pressure jacket.

9. The fluid injection apparatus of claim 6, wherein the light-diffusing device comprises a lens.

10. The fluid injection apparatus of claim 9, wherein the lens extends longitudinally along an inner surface of the pressure jacket.

11. The fluid injection apparatus of claim 6, wherein the light-diffusing device comprises an etched area formed on the pressure jacket.

12. The fluid injection apparatus of claim 11, wherein the etched area extends longitudinally along an inner surface of the pressure jacket.

13. The fluid injection apparatus of claim 6, wherein the light-diffusing device comprises a light-diffusing strip.

14. The fluid injection apparatus of claim 13, wherein the light-diffusing strip comprises white polycarbonate material.

15. The fluid injection apparatus of claim 1, wherein the wall of the pressure jacket defines a groove in an inner surface thereof, and wherein the pressure jacket assembly comprises a light-diffusing strip disposed in the groove for diffusing light passing through the wall of the pressure jacket.

16. The fluid injection apparatus of claim 15, wherein the light-diffusing strip comprises white polycarbonate material.

17. The fluid injection apparatus of claim 15, wherein the groove is trapezoidal shaped in cross section having two inward facing projections for retaining the light-diffusing strip in the groove.

18. The fluid injection apparatus of claim 14, wherein the groove extends longitudinally along the inner surface of the pressure jacket.

19. The fluid injection apparatus of claim 1, wherein the pressure jacket is made of substantially clear plastic.

20. The fluid injection apparatus of claim 19, wherein the substantially clear plastic is selected from the group consisting of polypropylene, polyethylene, and polycarbonate.
