Abstract
Described herein are syringe caps including a plug portion and a protruding member extending from one end of the plug portion. The protruding member can extend a length greater than a depth of an accumulated component in the syringe. Also described herein, are systems including a syringe containing a composition and a syringe cap. The syringe cap can include a luer-lock with a projecting member that projects into the syringe. The projecting member can assist in creating a tunnel through the accumulated material thereby allowing degassing of the composition. The projecting member can also help to prevent accumulation of a radiopaque visualization agent or contrast agent that may accumulate along one end of the syringe.
Claims24
A syringe cap including:
- a plug portion having a first end and a second end, where in an incorrect storage configuration the plug portion is connected to a delivery end of a syringe, and
- a protruding member extending from the second end of the plug portion about 2 mm to about 20 mm, wherein in the incorrect storage configuration, about 2 mm to about 20 mm of the protruding member is in direct contact with a composition including a first component and a second component housed in the syringe, and wherein the protruding member extends a length greater than a depth of the second component when accumulated.
A system for degassing a composition in a syringe, the system comprising:
- a syringe including a connection at a delivery end;
- a syringe cap including a plug portion having a first end and a second end, wherein the plug portion is configured to attach to the connection and a protruding member extending from the second end of the plug portion;
- the composition in the syringe that includes a first component and a second component, wherein the second component accumulates when the syringe is stored, and wherein the protruding member extends a length greater than a depth of the second component when accumulated.
A syringe system comprising:
- a syringe including a plug portion at a delivery end of the syringe, wherein the plug portion includes a protruding member extending into the syringe;
- a composition in the syringe that comprises a first component and a second component, wherein the second component accumulates when the syringe is stored;
- packaging having one or more correct storage configurations wherein the syringe is oriented such that the second component accumulates away from the delivery end;
- and
- wherein the protruding member extends a length greater than a depth of the second component when accumulated.
