POWER INJECTOR WITH MOVABLE JOINT-INTEGRATED SIGNAL TRANSMISSION CONNECTOR
A power injector that incorporates at least one signal transmission connector in a movable joint (e.g., between a powerhead and a support or stand; between at least one adjacent pair of support sections of a support for the powerhead) is disclosed. Such a signal transmission connector may be in the form of a slip ring module, but in any case is part of the signal transmission link to the powerhead. At least that portion of a signal transmission conduit that is adjacent to the powerhead may be disposed within the interior of the corresponding portion of the support or stand, thereby reducing the potential that an individual will grab onto the signal transmission conduit when attempting to move at least part of the power injector, to change the position of the powerhead, or both.
1 . A power injector, comprising:
a support;
a cable comprising a first wire;
a powerhead, wherein said support provides mechanical support to said powerhead, and wherein said powerhead comprises a drive motor and an axially movable drive ram that is aligned with a location where a syringe may be installed on said powerhead; and
a pivot that extends between said support and said powerhead such that said powerhead is pivotable relative to said support, wherein said pivot comprises an electrical signal transmission connector which in turn comprises an outer housing and an inner housing that are rotatable relative to each other and that are electrically connected, wherein said first wire of said cable extends to and is electrically connected with one of said outer housing and said inner housing, and wherein the other of said outer housing and said inner housing is electrically connected with said powerhead by a second wire.
2 . The power injector of claim 1 , wherein said support comprises a portable base and a column that extends upwardly from said base.
3 . The power injector of claim 1 , wherein a first zone comprises said powerhead and at least a first section of said support that is adjacent to said powerhead, wherein none of said cable and none of said electrical signal transmission connector is exteriorly disposed throughout said first zone.
4 . The power injector of claim 1 , wherein at least part of said cable is disposed within said support.
5 . The power injector of claim 1 , wherein said inner housing and said outer housing each rotate about a first axis, and wherein said powerhead is also pivotable about said first axis.
6 . The power injector of claim 1 , wherein said electrical signal transmission connector is disposed within an interior of said pivot.
7 . The power injector of claim 1 , wherein said electrical signal transmission connector comprises a slip ring module.
8 . The power injector of claim 1 , wherein said electrical signal transmission connector comprises a rotary connector.
9 . The power injector of claim 1 , wherein said first wire remains stationary while said powerhead is pivoted relative to said support column and that moves said second wire relative to said first wire.
