Abstract
A fitting for use in performing a vascular puncture includes a system for rapidly and securely stabilizing an intravascular catheter or needle to a patient's skin upon insertion of the needle or catheter into a blood vessel. The hub of the needle or catheter has upper and lower lateral wings extending from its opposite sides. The wings are folded up over the hub and gripped together while a vascular puncture is made and then the lower wings, which have adhesive under surfaces, are released and dabbed onto the skin to rapidly stabilize the fitting. The upper wings can be taped down over the lower wings to effect a more permanent attachment of the fitting.
Claims11
A fitting for use in forming a vascular puncture comprising an elongate hub having a longitudinal axis, a blood vessel-entering element extending axially from one end of said hub, tubing attachment means at the other end of said hub and means for stabilizing the fitting on a patient's skin upon insertion of said blood vessel-entering element into a blood vessel, said stabilizing means including first and second substantially laminar wings extending laterally from said hub on opposite sides of said axis respectively, a third substantially laminar wing extending laterally from said hub under one of said first and second wings, each of said first, second and third wings being capable of independent flexing movements about said hub and said third wing having an undersurface with contact adhesive means covering a portion of said surface, wherein said undersurface of said third wing comprises a hub-covering portion, an outer gripping portion and a central portion between said hub-covering portion and said gripping portion and wherein said contact adhesive is provided on said central portion.
A fitting for use in performing a vascular puncture comprising an elongate hub having a longitudinal axis, a blood vessel-entering element extending axially from one end of said hub, and tubing attachment means at the other end of said hub, said fitting further comprising:
- preliminary stabilizing means for providing positional stability of said fitting on a patient's skin immediately after insertion of said blood vessel-entering element into that patient's blood vessel, said preliminary stabilizing means comprising a first substantially laminar wing-like member having top and bottom surfaces and extending laterally from said hub, said first wing-like member being capable of flexure about said longitudinal axis and having a coating of adhesive material on at least a portion of its bottom side;
- and
- further means for gripping said fitting during vascular insertion of said element and stabilizing the element on the patient's skin subsequent to stabilization by said preliminary stabilizing means, said further means comprising second and third substantially laminar wing-like members having top and bottom sides and normally extending laterally from said hub on opposite sides, respectively, of said axis, said second wing-like member normally extending over said first wing-like member, said second and third wing-like members being flexible to permit their independent flexure about said hub such that said second and third wing-like members can be flexed to bring their top sides toward one another to permit said first and second wing-like members to serve as a handle during vascular insertion of said element.
