Abstract
Abstract An intravenous needle assembly for administering medication into a patient comprising a cannula having a hub portion from the opposite sides of which extend a pair of hub wing sections. The hub wing sections are adapted to flex in either direction around said hub into abutting contact with one another to form a gripping handle for holding the cannula while it is being inserted into the vein of the patient. The wing portions include interlocking means thereon which serve both to lock the wing portions together in an upright position thereby preventing them from slipping relatively to one another and also to provide a roughened surface on the outside of said wing portions thereby lessening the danger of the fingers of the person handling said needle assembly from slipping on said wing portions.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
133 words
An intravenous needle assembly comprising: a cannula having a pointed end; a hub means on the other end of said cannula; and a pair of flexible wing sections normally extending laterally from opposite sides of said hub means in a direction substantially perpendicular to the axis of said hub means and joined thereto along areas or lines of reduced thickness disposed at an angle with respect to the axis of the cannula and diverging toward said pointed end so that said flexible wing sections may be readily folded relative to said Hub means about said lines of reduced thickness and brought into abutting contact with one another in a forwardly inclined vertically disposed position to define a wedge-shaped handle means to be grasped for inserting said cannula into the vein of a patient.
Claim 2
Dependent Claim
133 words
An intravenous needle assembly comprising: a cannula having a pointed end; a hub means on the other end of said cannula; and a pair of flexible wing sections normally extending laterally from opposite sides of said hub means in a direction substantially perpendicular to the axis of said hub means and joined thereto along areas or lines of reduced thickness disposed at an angle with respect to the axis of the cannula and diverging toward said pointed end so that said flexible wing sections may be readily folded relative to said Hub means about said lines of reduced thickness and brought into abutting contact with one another in a forwardly inclined vertically disposed position to define a wedge-shaped handle means to be grasped for inserting said cannula into the vein of a patient.
Claim 3
Dependent Claim
55 words
An intravenous needle assembly as in claim 1, wherein said wing sections have interlocking means on at least one surface thereof, the interlocking means on one wing section adapted to engage with the interlocking means on the other wing section when the wing sections are folded together to lock and maintain the wing sections together.
Claim 4
Dependent Claim
21 words
An intravenous needle assembly as in claim 2, wherein said interlocking means comprises a projection on at least one wing section.
Claim 5
Dependent Claim
21 words
An intravenous needle assembly as in claim 2, wherein an interlocking means is provided on each surface of each wing section.
Claim 6
Dependent Claim
86 words
An intravenous needle assembly as in claim 2, wherein said interlocking means comprises a circular rib on each wing section, the outer diameter of the rib on one wing section being substantially the same as the inner diameter of the circular rib on the other wing section so that when the wing sections are folded together, the circular rib on said one wing section is snugly fitted within the circular rib on the other wing section to lock the wing sections together against relative movement therebetween.
Claim 7
Dependent Claim
58 words
An intravenous needle assembly as in claim 4, wherein the interlocking means on each surface of each rib section comprises a circular rib, the outer diameter of the circular rib on one side of one wing section being substantially the same as the inner diameter of the circular rib on the corresponding surface of the other wing section.
Claim 8
Dependent Claim
67 words
An intravenous needle assembly as in claim 2, wherein said interlocking means comprises an elongate rib on at least one surface of one wing section and a pair of spaced-parallel elongate ribs on one surface of the other wing section, said one rib adapted to fit snugly between said spaced-parallel ribs when said wing sections are folded together to lock said wing section against relative movement therebetween.
Claim 9
Dependent Claim
80 words
An intravenous needle assembly as in claim 7, wherein the other surface of said one wing section includes a pair of spaced parallel elongate ribs thereon and the other surface of said other wing section includes an elongate rib thereon corresponding to the ribs on said one surface of said wing sections, said ribs on said other surface of said wing sections adapted to interlock when said wing sections are folded in the opposite direction relative to said hub means.
Claim 10
Dependent Claim
22 words
An intravenous needle assembly as in claim 7, wherein said ribs are disposed at an angle to the axis of said cannula.
Claim 11
Dependent Claim
99 words
An intravenous needle assembly comprising: a cannula having a sharpened end; a hub means on the other end of said cannula; a pair of flexible wing sections normally extending laterally from opposite sides of said hub means; and releasable interlocking means on both surfaces of each of said wing sections, the interlocking means on adjacent surfaces of the wing sections adapted to interengage and interlock said wing sections against relative movement therebetween when said wing sections are folded together about said hub means and the interlocking means on the opposite surfaces of the wing sections defining roughened finger-gripping surfaces.
Claim 12
Dependent Claim
99 words
An intravenous needle assembly comprising: a cannula having a sharpened end; a hub means on the other end of said cannula; a pair of flexible wing sections normally extending laterally from opposite sides of said hub means; and releasable interlocking means on both surfaces of each of said wing sections, the interlocking means on adjacent surfaces of the wing sections adapted to interengage and interlock said wing sections against relative movement therebetween when said wing sections are folded together about said hub means and the interlocking means on the opposite surfaces of the wing sections defining roughened finger-gripping surfaces.
Claim 13
Dependent Claim
97 words
An intravenous needle assembly as in claim 10, wherein said interlocking means comprises a circular rib, the outside diameter of the circular rib on one wing section being substantially the same as the inside diameter of the circular rib on the confronting surface of the other wing section, said circular rib on said one wing section adapted to fit snugly within the circular rib on the other wing section to lock said wing sections together, the circular ribs on the other surface of each wing section defining the gripping means for securely gripping the folded-together wing sections.
Claim 14
Dependent Claim
66 words
An intravenous needle asSembly as in claim 10, wherein said interlocking means comprises an elongate rib formed on at least one surface of one wing section and a pair of spaced-parallel elongate ribs on at least one surface of the other wing section, said one elongate rib adapted to fit snugly between said parallel-spaced ribs when said wing sections are folded together about said hub means.
Claim 15
Dependent Claim
24 words
An intravenous needle assembly as in claim 12, wherein said elongate ribs are disposed at an angle relative to the axis of said cannula.
