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 carry a tapered foam pad with a pressure sensitive adhesive on the lower surface thereof when applied to the skin of a patient'"'"'s body. After the insertion of the needle in a vein, the needle is angled downwardly into the vein to position the beveled pointed end away from the walls of the vein.

Claims

1. An improvement in an intravenous needle assembly having an elongated flexible body member with a central section and oppositely extending sections wih 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 first 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, and secondary means for rotating said hollow needle on its longitudinal axis, said first 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 and said secondary means comprising a cylindrical member rotatably located in said central section and transversely of said elongated flexible body member, said hollow needle positioned in said cylindrical member on said transverse horizontal plane whereby positioning said hollow needle of said assembly through a patient'"'"'s skin and into a vein of said patient and engaging said tapered pad on said patient'"'"'s skin 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.

2. The improvement in an intravenous needle assembly set forth in claim 1 and wherein said oppositely extending sections are thin distortable members positioned on said transverse horizontal plane.

3. 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.

4. The improvement in an intravenous needle assembly set forth in claims 2, 1 or 3 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.
