Abstract
An adapter for use with a syringe and a power injector includes an outer ring having a first end configured for passage of an end of a syringe having at least one flange. An inner ring is disposed coaxially within the outer ring. The inner ring has a first end including at least one flange slot. A magnet fixed relative to the inner ring such that when the syringe end is disposed in the outer ring and the at least one flange engages the at least one flange slot, rotation of the syringe causes rotation of the inner ring and magnet relative to the outer ring.
Claims18
A medical system for injecting a fluid comprising:
- a power injector with a ram for pushing fluid from a syringe, the injector including:
- a faceplate, and
- an adapter for use with a syringe, the adapter engaging the faceplate, the adapter including:
- an outer ring having a first end configured for passage of an end of a syringe having at least one flange,
- an inner ring disposed coaxially within the outer ring, the inner ring having a first end including at least one flange slot, and
- a magnet fixed relative to the inner ring,
- where when the syringe end is disposed in the outer ring and the at least one flange engages the at least one flange slot, rotation of the syringe causes rotation of the inner ring and magnet relative to the outer ring.
A method for operating a medical injector system comprising:
- providing a power injector with a ram and having a faceplate,
- providing an adapter including
- an outer ring having a first end,
- an inner ring disposed coaxially within the outer ring, the inner ring having a first end including at least one flange slot, and
- a magnet fixed relative to the inner ring,
- providing a syringe having:
- a barrel having a distal end and a proximal end and a defining an interior volume therebetween,
- at least one flange extending from proximal end, and
- a delivery tip extending from the distal end,
- loading the syringe on the power injector by passing the proximal end of the syringe through the first end of the outer ring, engaging the at least one flange slot with the at least one flange, and
- rotating the syringe to causes rotation of the inner ring and magnet relative to the outer ring.
An adapter for use with a syringe and a power injector, the adapter comprising:
- an outer ring having a first end configured for passage of an end of a syringe having at least one flange,
- an inner ring disposed coaxially within the outer ring, the inner ring having a first end including at least one flange slot, and
- a magnet fixed relative to the inner ring,
- where when the syringe end is disposed in the outer ring and the at least one flange engages the at least one flange slot, rotation of the syringe causes rotation of the inner ring and magnet relative to the outer ring.
