Abstract

An injector system for use in delivering a fluid to a patient in a medical procedure includes an injection head unit having at least one pressurizing member. The pressurizing member is in communicative connection with a remote power source via at least one non-rigid drive connection. A connecting member is attached to the injection head unit. The injector system further includes a base unit having a base member that is attachable to a surface and a support member to which the connecting member is attachable.

Claims

1. An injector system comprising:

an injection head unit comprising at least one pressurizing member;

a stationary base unit adapted to be attached to a surface other than a surface of the injector system; and

a connecting member connected to the injection head unit and the stationary base unit.

2. The injector system of claim 1 wherein the connecting member is removably connected to the stationary base unit.

3. The injector system of claim 1 wherein the connecting member is movably connected to the stationary base unit.

4. The injector system of claim 3 wherein the connecting member is rotatably connected to the stationary base unit.

5. The injector system of claim 4 wherein the base unit comprises a bushing member and the connecting member is rotatably connected to the base unit via cooperation with the bushing member, the bushing member comprising an adapter to accept different connecting members.

6. The injector system of claim 1 wherein the pressurizing member is connected to a remote power source via at least one non-rigid drive connection and the connecting member is generally cylindrical and defines a passage therethrough, the non-rigid drive connection being connected to the pressurizing member via the passage in the connecting member.

7. The injector system of claim 6 wherein the base unit defines a portal through which the non-rigid connection passes to connect to the remote power source.

8. The injector system of claim 1 wherein the connecting member is movably connected to the injection head unit.

9. The injector system of claim 1 wherein the connecting member comprises two or more connected sections.

10. The injector system of claim 9 wherein the two or more connected sections are adapted to be rotated relative to each other.

11. The injector system of claim 9, further comprising a coupler for attaching the two or more connected sections to each other.

12. The injector system of claim 1 wherein the connecting member is rotatably connected to the injection head unit and the stationary base unit.

13. The injector system of claim 1 wherein the surface is a wall, a ceiling or a post.

14. The injector system of claim 1 wherein the stationary base unit is attached to the surface by means of fasteners or adhesives.

15. The injector system of claim 1 wherein the at least one pressurizing member comprises a drive mechanism.

16. A method for delivering fluid to a patient in a medical procedure, the method comprising:

attaching a base unit to a surface other than a surface of the injector system;

attaching an injection head unit to the base unit via a connecting member that cooperates with the base unit; and

activating a pressurizing member in the injection head unit to deliver fluid to the patient.

17. The method of claim 16 wherein the pressurizing member in the injection head unit is connected to a power source by means of a non-rigid drive connection.

18. A method of adapting an injector system for use in confined spaces, the injector system comprising an injection head unit, and a connecting member attached to the head unit at a first end of the connector and attached to a mobile floor stand at a second end of the connecting member, the method comprising:

attaching a base unit to a surface other than a surface of the injector system;

removing the connecting member from attachment with the mobile floor stand; and

removably connecting the second end of the connecting member to the base unit.

19. The method of claim 18 wherein the injector system further comprises a power source connected to at least one drive member in the injection head unit via at least one non-rigid drive connection.

20. The method of claim 18, further comprising:

removing the second end of the connecting member from the base unit; and

reattaching the second end of the connecting member to the mobile floor stand.
