Abstract
Abstract A hypodermic needle guard designed to avoid needle sticks comprising a hand shield in the form of a flat plate with a flexible, tubular needle cap holder connected about a hole in the plate's center. Needle cap-enclosed hypodermic needles attached to medical appliances such as syringes, are inserted through the hole into the holder, where the user grasps the cap through the holder tube by compressing the tube with finger pressure. The needle attached to the appliance is then withdrawn. The process is reversed to safely recap the hyperdermic needle.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
106 words
A medical protection device comprising a hand shield with a hypodermic needle cap holder tube connected thereto, said hand shield comprising a flat plate with a hole suitable for the insertion of a needle cap substantially in the center thereof, and said needle cap holder tube comprising a transparent flexible, cylindrical tube having a wall thickness of between 0.04 to 0.06 inches and an open end therein connected about said hole at right angles to said plate, and having a closed end therein opposite to said open end, said tube being compressible about its transverse axis through the application of pinching finger pressure by a user.
Claim 2
Dependent Claim
106 words
A medical protection device comprising a hand shield with a hypodermic needle cap holder tube connected thereto, said hand shield comprising a flat plate with a hole suitable for the insertion of a needle cap substantially in the center thereof, and said needle cap holder tube comprising a transparent flexible, cylindrical tube having a wall thickness of between 0.04 to 0.06 inches and an open end therein connected about said hole at right angles to said plate, and having a closed end therein opposite to said open end, said tube being compressible about its transverse axis through the application of pinching finger pressure by a user.
Claim 3
Dependent Claim
58 words
A device according to claim 1 wherein said plate is formed with a cylindrical collar as an integral part thereof, said collar being concentric to, and extending at right angles from said hole, and wherein the open end of said tube makes a force fit over said collar, thereby effecting a connection between said tube and said plate.
Claim 4
Dependent Claim
20 words
A device according to claim 1 in which said plate and said tube are formed from substantially transparent plastic materials.
Claim 5
Dependent Claim
23 words
A device according to claim 3 in which said plate is square, having sides of from about two inches to three-and-one-half inches long.
Claim 6
Dependent Claim
49 words
The process of capping a hypodermic needle comprising inserting said needle into a needle cap contained in the needle cap holder tube of the device of claim 1, said needle cap being firmly held within said holder by compressing said holder tube against said needle cap with finger pressure.
Claim 7
Independent Claim
125 words
A device for protecting the hands of a user of a needle for injecting or extracting body fluids having a needle sheath from accidental needle sticks while unsheathing or resheathing said needle, said device comprising: a hand shield, said hand shield comprising a flat plate with an unobstructed hole therethrough positioned substantially in the center of said plate; a transparent flexible cylindrical tube having a wall thickness of between 0.04 to 0.06 inches and one open end therein, said tube being sufficiently flexible about its transverse axis to be compressed by pinching finger pressure of the user to grasp a needle sheath placed therein; and a means for connecting said open end of said tube about said hole at a right angle to said plate.
Claim 8
Independent Claim
125 words
A device for protecting the hands of a user of a needle for injecting or extracting body fluids having a needle sheath from accidental needle sticks while unsheathing or resheathing said needle, said device comprising: a hand shield, said hand shield comprising a flat plate with an unobstructed hole therethrough positioned substantially in the center of said plate; a transparent flexible cylindrical tube having a wall thickness of between 0.04 to 0.06 inches and one open end therein, said tube being sufficiently flexible about its transverse axis to be compressed by pinching finger pressure of the user to grasp a needle sheath placed therein; and a means for connecting said open end of said tube about said hole at a right angle to said plate.
Claim 9
Dependent Claim
59 words
The device of claim 6 wherein the means for connecting comprises a cylindrical collar formed integral to said plate, said collar being concentric to, and extending at right angles from, said hole, and said collar being sized to frictionally engage the inner surface of the open end of said tube, thereby effecting connection between said plate and said tube.
Claim 10
Dependent Claim
18 words
The device of claim 6 wherein said plate and said tube are formed from substantially transparent plastic materials.
Claim 11
Dependent Claim
21 words
The device of claim 6 wherein the plate is square, having sides of from about two inches to about three-and-one-half inches.
