Abstract
Abstract A hard-nosed bullet for mounting on a charged cartridge for use in a firearm is provided having a housing into which an injection plunger is slidably mounted. A plurality of injection pistons are mounted on the plunger, each of which is adapted to slide into one of a plurality of passages within the bullet head. Into each of the passages a sterile capsule containing a flexible injection needle and a fluid is inserted. Upon impact with a target the plunger moves forward, pushing the pistons through the passages, thereby rupturing the capsule and forcing the needles to penetrate the outer surface of the bullet, thus injecting the fluid into the target.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
148 words
A hard-nosed bullet for mounting on a cartridge of the type used in a firearm comprising a housing, an injection plunger slidably mounted for movement in said housing in response to an abrupt change in the forward momentum of the bullet after the bullet has been fired, a plurality of injection pistons, each of said pistons being mounted on said plunger, said bullet having a plurality of passages extending therethrough, each of said pistons extending at least partially into one of said passages, a plurality of capsules each containing a fluid and an injection needle, each of said capsules mounted in one of said passages in front of one of said pistons, said injection plunger causing the movement of said pistons through said passages upon the occurrence of said abrupt change in forward momentum to rupture the capsule and force the injection needles and fluid through said passages.
Claim 2
Dependent Claim
148 words
A hard-nosed bullet for mounting on a cartridge of the type used in a firearm comprising a housing, an injection plunger slidably mounted for movement in said housing in response to an abrupt change in the forward momentum of the bullet after the bullet has been fired, a plurality of injection pistons, each of said pistons being mounted on said plunger, said bullet having a plurality of passages extending therethrough, each of said pistons extending at least partially into one of said passages, a plurality of capsules each containing a fluid and an injection needle, each of said capsules mounted in one of said passages in front of one of said pistons, said injection plunger causing the movement of said pistons through said passages upon the occurrence of said abrupt change in forward momentum to rupture the capsule and force the injection needles and fluid through said passages.
Claim 3
Dependent Claim
25 words
The bullet according to claim 1 wherein said bullet is weighted such that the front portion of the bullet is heavier than the rear portion.
Claim 4
Dependent Claim
53 words
The bullet according to claim 1 wherein each of said passages comprises an elongated opening having a front portion and a rear portion, said rear portion being adapted to accept one of said capsules and one of said pistons and said front portion having a substantially smaller cross section than said rear portion.
Claim 5
Dependent Claim
27 words
The bullet according to claim 3 further comprising a plurality of non-toxic seals, one of which is disposed within the front portion of each of said passages.
Claim 6
Dependent Claim
35 words
The bullet according to claim 1 wherein said needle contained within said capsule further comprises a base, said base having a larger cross section than the cross section of the front portion of said passage.
Claim 7
Dependent Claim
28 words
The bullet according to claim 1 further comprising an outer shell, said shell being penetrable by each of said needles when said needles are forced through said passages.
Claim 8
Dependent Claim
35 words
The bullet according to claim 6 further comprising a cap to seal the rear portion of said shell, said cap being spaced from said plunger such that accidental displacement of plunger upon firing is minimized.
Claim 9
Dependent Claim
28 words
The bullet according to claim 1 further comprising a removable lock screw to maintain said plunger in a position such that accidental rupture of said bullet is prevented.
Claim 10
Dependent Claim
27 words
The bullet according to claim 1 wherein said fluid and said needle are sterile and maintained in this condition by said capsule until said capsule is ruptured.
Claim 11
Dependent Claim
26 words
The bullet according to claim 1 further comprising means for limiting the extension of said needle to a desired length beyond the surface of said bullet.
