Abstract
Abstract A needle safety device, which is usable on long, short, straight or curved needles, is actuated to enclose the injecting end of a needle when an engagement surface of the device is slid beyond the injecting end. A unitary or multiple piece clip is provided which is slideable from a first position wherein a hypodermic needle is usable for injection purposes to a second position wherein the injecting end of the hypodermic needle is covered rendering the needle unusable and protected.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
175 words
A unitary safety device for use on a hypodermic needle having an injecting end, said device being slideable between a first position and a second position on said hypodermic needle, said device comprising: a first portion having first and second engagement surfaces, said first engagement surface being in slideable contact with the periphery of said hypodermic needle when said device is in said first position and said second engagement surface being in abutting relation with said injecting end of said hypodermic needle when said device is in said second position; a second portion having a third engagement surface being in slideable contact with said hypodermic needle; and an integral intermediate portion disposed intermediate to said first portion and said second portion, said intermediate portion having a hole, said hole being dimensioned to fit slideably about said hypodermic needle when said device is in said first position and said hole having an inner surface that frictionally engages the periphery of said hypodermic needle to grasp said hypodermic needle when said device is in said second position.
Claim 2
Dependent Claim
175 words
A unitary safety device for use on a hypodermic needle having an injecting end, said device being slideable between a first position and a second position on said hypodermic needle, said device comprising: a first portion having first and second engagement surfaces, said first engagement surface being in slideable contact with the periphery of said hypodermic needle when said device is in said first position and said second engagement surface being in abutting relation with said injecting end of said hypodermic needle when said device is in said second position; a second portion having a third engagement surface being in slideable contact with said hypodermic needle; and an integral intermediate portion disposed intermediate to said first portion and said second portion, said intermediate portion having a hole, said hole being dimensioned to fit slideably about said hypodermic needle when said device is in said first position and said hole having an inner surface that frictionally engages the periphery of said hypodermic needle to grasp said hypodermic needle when said device is in said second position.
Claim 3
Dependent Claim
33 words
The hypodermic needle safety device of claim 1 further comprising a fourth engagement surface being in frictional engagement with the periphery of said hypodermic needle when said device is in said second position.
Claim 4
Dependent Claim
26 words
The hypodermic needle safety device of claim 1 wherein said injecting end of said hypodermic needle is deformed when said device is in said second position.
Claim 5
Dependent Claim

The safety device of claim 1, wherein said device is of unitary plastic construction.
Claim 6
Dependent Claim
32 words
The device of claim 1, wherein at least one of said first and said second portions further comprises a guide means for aligning said device axially with respect to said hypodermic needle.
Claim 7
Dependent Claim
28 words
The device of claim 1, further including an antiseptic medium for wiping said needle upon slideable movement of said device from said first position to said second position.
Claim 8
Dependent Claim
47 words
The device of claim 4, wherein said first engagement surface is biased toward said needle when said device is disposed in said first position and wherein said second engagement surface is actuated into abutting relation upon slideable movement of said first engagement surface to said second position.
Claim 9
Dependent Claim
25 words
The device of claim 7, wherein said first engagement surface is biased toward said needle by spring biasing caused by said first and second portions.
Claim 10
Dependent Claim
21 words
The device of claim 1, further comprising biasing means for activating said device from said first position to said second position.
Claim 11
Dependent Claim
166 words
A hypodermic needle, having a safety device, said hypodermic needle having an injection end, said device being slideable on said needle from a first injecting end exposing position to a second injection end covering position, said device comprising; a first member portion having a first needle engagement surface and a second injecting end protection surface; said first needle engagement surface being biased toward said needle when said device is in said first position and wherein said second injection end protection surface is actuated into confronting relation with said injecting end of said needle upon slideable movement of said device from said first injecting end exposing position to said second injection end covering position; a second member portion which is disposed adjacent to said needle when said device is in said first position and having a hole with an inner surface which frictionally engages said needle to resist slideable movement of said device with respect to said needle when said device is disposed in said second position.
Claim 12
Dependent Claim
166 words
A hypodermic needle, having a safety device, said hypodermic needle having an injection end, said device being slideable on said needle from a first injecting end exposing position to a second injection end covering position, said device comprising; a first member portion having a first needle engagement surface and a second injecting end protection surface; said first needle engagement surface being biased toward said needle when said device is in said first position and wherein said second injection end protection surface is actuated into confronting relation with said injecting end of said needle upon slideable movement of said device from said first injecting end exposing position to said second injection end covering position; a second member portion which is disposed adjacent to said needle when said device is in said first position and having a hole with an inner surface which frictionally engages said needle to resist slideable movement of said device with respect to said needle when said device is disposed in said second position.
Claim 13
Dependent Claim
16 words

Claim 14
Dependent Claim
28 words
The device of claim 10, further comprising an antiseptic medium for wiping said needle upon slideable movement of said device from said first position to said second position.
Claim 15
Dependent Claim
18 words
The device of claim 10, wherein said needle is deformed when said device is in said second position.
Claim 16
Dependent Claim
13 words
The device of claim 10 wherein said device is of unitary plastic construction.
