Abstract
Abstract A sheath for a hypodermic needle or other sharp instrument which is adapted with an apparatus to protect the hand of a person attempting to insert the hypodermic needle or sharp instrument into the sheath and the protection apparatus, wherein the protection apparatus generally comprises a radial shield or a shroud extending out from the sheath a distance which is adequate to block, deflect, or separate a stray hypodermic needle which inadvertantly misses the entry port of the sheath from a person's sheath-holding hand.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
145 words
An apparatus for the sheathing of a hypodermic needle which is adapted to protect a person's sheath-holding hand during sheathing, said apparatus comprising; a sheath for a hypodermic needle; said sheath being fastened at some point to at least one joining member, said joining member being further fastened to a shrouding member such that such fastened joining member is of adequate strength and rigidity to remain fastened under the pressure caused by the impact of a stray needle during a sheathing operation to either said joining member, said sheath, or said shrouding member; said shrouding member further comprising an external surface which is generally parallel with the external surface of said sheath and surrounds said sheath along some part of the length of said sheath; said shrouding member external surface being, at all points, some distance from the nearest point on said sheath external surface.
Claim 2
Independent Claim
145 words
An apparatus for the sheathing of a hypodermic needle which is adapted to protect a person's sheath-holding hand during sheathing, said apparatus comprising; a sheath for a hypodermic needle; said sheath being fastened at some point to at least one joining member, said joining member being further fastened to a shrouding member such that such fastened joining member is of adequate strength and rigidity to remain fastened under the pressure caused by the impact of a stray needle during a sheathing operation to either said joining member, said sheath, or said shrouding member; said shrouding member further comprising an external surface which is generally parallel with the external surface of said sheath and surrounds said sheath along some part of the length of said sheath; said shrouding member external surface being, at all points, some distance from the nearest point on said sheath external surface.
Claim 3
Dependent Claim
207 words
The invention described in claim 1 in which said shrouding member is adapted to be capped, said apparatus further comprising; a closing member, said closing member making a full radial connection between said sheath and said shrouding member so as to close off atmospheric communication between the shrouding member-enclosed space at the end of said shrouding member which is nearest the open end of said sheath and the ambient air of the surrounding space; a capping apparatus, said capping apparatus further comprising; a hollow cap member having a diameter equal to the diameter of said said shrouding member end; a said hollow cap member being of length which is at least equal to the distance from the outer perimeter of said shrouding member end and the open end of said hollow sheath member as extended by a needle housed within; said hollow cap member having one closed cap end and one open cap end; said open cap end having a perimeter which is congruent with the edge of said said shrouding member end and further adapted with a means for fastening said cap to said shrouding member end such that said capping apparatus encloses the open end of said hollow sheath member and any needle housed within.
