Abstract
Abstract The invention discloses a multi-shot artificial insemination device and interchangeable and disposable reservoir tubes connectable thereto such that plural doses of liquid semen are sequentially discharged from one end of a tube by step-wise displacement of a plunger into another end of the tube. The apparatus is configured for easy, secure connection and support of a rear end of a reservoir tube to the device while a freely protruding front end of the reservoir is of sufficient length and shape for insertion into an animals cloaca for insemination thereof upon actuation of the device.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
137 words
A multi-shot artificial insemination apparatus comprising: a body presenting a snout and a passage through said snout; a disposable reservoir means for containing plural doses of liquid semen and comprising a tube having a rear end; said snout and said tube rear end being cooperatively configured to fit said rear end to said snout in alignment with said passage; said tube further comprising a blunt convergent front end and a length from said rear end to said front end and freely protruding sufficiently far from said snout for insertion of said tube into an animals cloaca to facilitate said insemination; a plunger extensible through said passage and into said tube rear end; and means for displacing said plunger stepwise to discharge successive doses of said liquid semen from said tube through said front end to said cloaca.
Claim 2
Dependent Claim
137 words
A multi-shot artificial insemination apparatus comprising: a body presenting a snout and a passage through said snout; a disposable reservoir means for containing plural doses of liquid semen and comprising a tube having a rear end; said snout and said tube rear end being cooperatively configured to fit said rear end to said snout in alignment with said passage; said tube further comprising a blunt convergent front end and a length from said rear end to said front end and freely protruding sufficiently far from said snout for insertion of said tube into an animals cloaca to facilitate said insemination; a plunger extensible through said passage and into said tube rear end; and means for displacing said plunger stepwise to discharge successive doses of said liquid semen from said tube through said front end to said cloaca.
Claim 3
Dependent Claim
21 words
Apparatus as in claim 1 wherein an internal diameter of said tube is substantially greater than a diameter of said passage.
Claim 4
Dependent Claim
44 words
Apparatus as in claim 2 wherein said snout comprises, externally in succession along said passage, an engagement surface means for fitting in said rear end of said tube and a free cylindrical surface of outer diameter less than the internal diameter of said tube.
Claim 5
Dependent Claim
25 words
Apparatus as in claim 1 and including a ring comprising an inner surface means for clamping said rear end of said tube onto said snout.
Claim 6
Dependent Claim
40 words
Apparatus as in claim 4 wherein said snout further comprises an externally threaded portion and said ring further comprises an internally threaded portion so that said ring may be secured to said body member by screwing said threaded portions together.
Claim 7
Dependent Claim
41 words
Apparatus as in claim 4 wherein said ring further comprises an elongate free end portion surrounding and supporting said rear end of said tube, said free end portion having an inner diameter slightly larger than an outer diameter of said tube.
Claim 8
Dependent Claim
30 words
Apparatus as in claim 4 wherein said inner surface means of said ring comprises a rounded read edge such that cutting of said rear end by said clamping is avoided.
Claim 9
Dependent Claim
33 words
Apparatus as in claim 4 wherein the rear end of said tube comprises a longitudinal slit such that fitting of said rear end onto said engagement surface means of said snout is facilitated.
Claim 10
Dependent Claim
23 words
Apparatus as in claim 1 wherein said front end of said tube has a convergent truncated cone shape with an inwardly turned lip.
Claim 11
Dependent Claim
27 words
Apparatus as in claim 1 wherein said passage and said snout are formed in a block member which is secured in a front portion of said body.
