Abstract
Abstract An intravenous needle assembly includes a hollow needle having a beveled point, the needle being positioned transversely of a central section of an elongated, flexible, foldable body having oppositely disposed wing sections. The needle is provided with a flexible connecting tube and a connector for attachment to a desired device, such as a syringe, bottle, etc. The central section mounting the needle and the oppositely disposed wing sections are tapered transversely with a pressure sensitive adhesive on the lower surface thereof for application to the skin of a patient's body. The needle is angled downwardly by the tapered structure when moved into the vein to position the beveled pointed end away from the walls of the vein.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
191 words
An improvement in an intravenous needle assembly having an elongated flexible body member with upper and lower surfaces with a central section and oppositely extending wing sections with respect thereto, and a hollow needle having a beveled end positioned through said central section transversely of said elongated flexible body member on a transverse horizontal plane; the improvement comprising means for tilting said elongated flexible body member and the hollow needle from said transverse horizontal plane to an angular transverse plane with respect to said transverse horizontal plane when said assembly is applied to a patient's skin, said means comprising at least one longitudinally extending transversely tapered resilient pad positioned on said elongated flexible body member in oppositely disposed relation to said central section and said hollow needle so that when said hollow needle of said assembly is positioned through a patient's skin and into a vein of said patient, said tapered flexible body member engages the patient'skin and tilts said central section and said hollow needle relative to said patient's skin and vein and spaces the beveled end of said hollow needle in unencumbered relation to the walls of said vein.
Claim 2
Dependent Claim
191 words
An improvement in an intravenous needle assembly having an elongated flexible body member with upper and lower surfaces with a central section and oppositely extending wing sections with respect thereto, and a hollow needle having a beveled end positioned through said central section transversely of said elongated flexible body member on a transverse horizontal plane; the improvement comprising means for tilting said elongated flexible body member and the hollow needle from said transverse horizontal plane to an angular transverse plane with respect to said transverse horizontal plane when said assembly is applied to a patient's skin, said means comprising at least one longitudinally extending transversely tapered resilient pad positioned on said elongated flexible body member in oppositely disposed relation to said central section and said hollow needle so that when said hollow needle of said assembly is positioned through a patient's skin and into a vein of said patient, said tapered flexible body member engages the patient'skin and tilts said central section and said hollow needle relative to said patient's skin and vein and spaces the beveled end of said hollow needle in unencumbered relation to the walls of said vein.
Claim 3
Dependent Claim
28 words
The improvement in an intravenous needle assembly set forth in claim 1 and wherein said angular transverse plane is located at about 10° from said transverse horizontal plane.
Claim 4
Dependent Claim
61 words
The improvement in an intravenous needle assembly set forth in claim 2 wherein pressure sensitive adhesive is located on said longitudinally extending, transversely tapered pad for holding said assembly in engagement with a patient's skin whereby said central section and said elongated flexible body member and said hollow needle are secured in angular relation to said patient's skin and said vein.
