Abstract
Abstract A handle for use in an intravenous needle assembly in which the handle comprises a body portion being connected via hinge portions to oppositely extending wing sections. The body portion of the handle has at its distal end an insertion aid in the form of laterally extending horns against which pressure may be applied when introducing the point of the needle of the intravenous needle assembly which comprises a needle, a hub which rigidly holds the needle and a handle as described above which is mounted on the needle hub in a manner which allows free rotation of the needle hub within the handle.

Claim 1
Independent Claim
149 words
A handle for use in an intravenous needle assembly for placing and maintaining an intravascular needle within a vein which comprises a body portion being connected via hinge portions to oppositely extending wing sections, in which said body portion has at its distal end an insertion aid in the form of a pair of laterally extending horns aginst which pressure may be applied when introducing the point of the needle beneath the skin and in which each of said wing portions of the handle has adjacent to the hinge a thinner portion having dimensions such that when the wings are folded the thinner portion conforms to and folds around the body portion in close fit therewith, each of said thinner portions carries a raised area on the surface which in use contacts the body portion when the wings are folded so as to apply pressure to the body portion.
Claim 2
Dependent Claim

A handle for use in an intravenous needle assembly for placing and maintaining an intravascular needle within a vein which comprises a body portion being connected via hinge portions to oppositely extending wing sections, in which said body portion has at its distal end an insertion aid in the form of a pair of laterally extending horns aginst which pressure may be applied when introducing the point of the needle beneath the skin and in which each of said wing portions of the handle has adjacent to the hinge a thinner portion having dimensions such that when the wings are folded the thinner portion conforms to and folds around the body portion in close fit therewith, each of said thinner portions carries a raised area on the surface which in use contacts the body portion when the wings are folded so as to apply pressure to the body portion.
Claim 3
Dependent Claim
143 words
An intravenous needle assembly for placing and maintaining an intravascular needle within a vein which assembly comprises (a) a needle (b) a hub which rigidly holds the needle and (c) a handle which is mounted on the hub in a manner which allows free rotation of the hub within the handle, in which said handle comprises a body portion connected via hinge portions to oppositely extending wing sections in which said body portion has at its distal end an insertion aid in the form of a pair of laterally extending horns against which pressure may be applied when introducing the point of the needle beneath the skin and in which the wing sections have thinner portions in which thinner portion carries a raised area which applies pressure to the body portion when the wings are folded thereby preventing rotation of the needle hub.
Claim 4
Dependent Claim
143 words
An intravenous needle assembly for placing and maintaining an intravascular needle within a vein which assembly comprises (a) a needle (b) a hub which rigidly holds the needle and (c) a handle which is mounted on the hub in a manner which allows free rotation of the hub within the handle, in which said handle comprises a body portion connected via hinge portions to oppositely extending wing sections in which said body portion has at its distal end an insertion aid in the form of a pair of laterally extending horns against which pressure may be applied when introducing the point of the needle beneath the skin and in which the wing sections have thinner portions in which thinner portion carries a raised area which applies pressure to the body portion when the wings are folded thereby preventing rotation of the needle hub.
