Claims Analysis

Total Claims: 12
Claim 1
Independent Claim 85 words
A device comprising: a needle capable of being cocked and then injected into the skin by a spring-loaded mechanism, said needle removably inserted into said spring-loaded mechanism; and needle ejecting means placed on said spring-loaded mechanism and engageable with said needle such that said needle ejecting means are capable of moving relative to said spring loaded mechanism to exert a force against said needle to eject said needle from said mechanism, said needle ejecting means further comprising a pair of prongs which abut said needle.
Claim 2
Independent Claim 85 words
A device comprising: a needle capable of being cocked and then injected into the skin by a spring-loaded mechanism, said needle removably inserted into said spring-loaded mechanism; and needle ejecting means placed on said spring-loaded mechanism and engageable with said needle such that said needle ejecting means are capable of moving relative to said spring loaded mechanism to exert a force against said needle to eject said needle from said mechanism, said needle ejecting means further comprising a pair of prongs which abut said needle.
Claim 3
Independent Claim 57 words
A device comprising: lancet holding means; a lancet inserted into said holding means; and lancet ejector means attached to said holding means and movable relative to said holding means to exert a force on said lancet to eject said lancet from said holding means, said lancet ejector means comprising a pair of prongs which abut said lancet.
Claim 4
Independent Claim 57 words
A device comprising: lancet holding means; a lancet inserted into said holding means; and lancet ejector means attached to said holding means and movable relative to said holding means to exert a force on said lancet to eject said lancet from said holding means, said lancet ejector means comprising a pair of prongs which abut said lancet.
Claim 5
Dependent Claim 35 words
The device of claim 2 wherein said lancet holding means contains an elongated tab and said lancet ejector means contains a notch into which said tab is placed, said tab movable relative to said notch.
Claim 6
Dependent Claim 74 words
The device of claim 2 further including cocking means attached to said holding means and ear means on said lancet ejector means, onto which pressure is placed to cause said lancet ejector notch to have the capability to remain stationary during cocking of said device, said lancet ejector prongs movable relative to said lancet holder during said cocking in order to exert force on said lancet to eject said lancet from said holding means.
Claim 7
Independent Claim 74 words
A device comprising: a generally cylindrical shell; spring loaded cocking means for cocking and firing said device and retractable within said shell; lancet holding means attached to said cocking means; a lancet attached to said holding means; and lancet ejector means attached to said holding means and capable of ejecting said lancet from said holding means and out of said shell; wherein said ejector means contains a pair of prongs which abut said lancet.
Claim 8
Independent Claim 74 words
A device comprising: a generally cylindrical shell; spring loaded cocking means for cocking and firing said device and retractable within said shell; lancet holding means attached to said cocking means; a lancet attached to said holding means; and lancet ejector means attached to said holding means and capable of ejecting said lancet from said holding means and out of said shell; wherein said ejector means contains a pair of prongs which abut said lancet.
Claim 9
Dependent Claim 37 words
The device of claim 5 wherein said lancet ejector means moves relative to said lancet holding means to exert a force on said lancet at said prongs such that said lancet is released from said holding means.
Claim 10
Dependent Claim 41 words
The device of claim 6 wherein said holding means comprises a collar with two ends, one said end which fits about said lancet such that said lancet is held within said end, and the other said end holding said ejector means.
Claim 11
Dependent Claim 35 words
A device of claim 6 wherein said lancet holding means contains an elongated tab and said lancet ejector means contains a notch into which said tab is placed, said tab movable relative to said notch.
Claim 12
Dependent Claim 65 words
The device of claim 6 wherein said lancet ejector means contains ear means onto which pressure is placed to cause said lancet ejector notch to have the capability to remain stationary during cocking of said device, said lancet ejector prongs moveable relative to said lancet holder during said cocking in order to exert force on said lancet to eject said lancet from said holding means.
