Abstract
Abstract The addition of one or more lateral ejecting holes in the end of the insemination device that is introduced into the entrance of the neck of the uterus of the cow, for depositing semen, will permit a better application of the semen and also will allow the device to be used not only for the insemination of bovines, but also for other animals of different species whose sexual anatomical characteristics are similar to those of cows, by adapting the size of the device to the particular characteristics of the other animals.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
140 words
Apparatus to facilitate the artificial insemination of bovines and similar species, comprising: a conventional semen injecting insemination pipette for bovines through which semen will be introduced with a syringe; a rigid tube having a diameter greater than the diameter of the pipette fitted over and attached to the distal end of the pipette; seal forming means attached to the rigid tube; an insemination tip formed at the distal end of the rigid tube and having a diameter less than the diameter of the pipette so that the distal end of the pipette extending into the tube abuts the tip, the insemination tip having an open ejection port at its end; at least one lateral ejection port formed on a lateral side of the insemination tip; wherein the rigid tube is about 4 cm long and about 5 mm in diameter.
Claim 2
Dependent Claim
140 words
Apparatus to facilitate the artificial insemination of bovines and similar species, comprising: a conventional semen injecting insemination pipette for bovines through which semen will be introduced with a syringe; a rigid tube having a diameter greater than the diameter of the pipette fitted over and attached to the distal end of the pipette; seal forming means attached to the rigid tube; an insemination tip formed at the distal end of the rigid tube and having a diameter less than the diameter of the pipette so that the distal end of the pipette extending into the tube abuts the tip, the insemination tip having an open ejection port at its end; at least one lateral ejection port formed on a lateral side of the insemination tip; wherein the rigid tube is about 4 cm long and about 5 mm in diameter.
Claim 3
Dependent Claim
26 words
The apparatus of claim 1 wherein the seal forming means is an inflatable balloon, and further comprising means to inflate the balloon attached to the balloon.
Claim 4
Dependent Claim
14 words
The apparatus of claim 1 wherein the seal forming means is a rigid balloon.
Claim 5
Dependent Claim
17 words
The apparatus of claim 1 further comprising a syringe attached to the opposite end of the pipette.
Claim 6
Independent Claim
188 words
A method of artificially inseminating bovines and similar species, comprising: providing a conventional bovine insemination pipette; providing a rigid tube having a diameter greater than the diameter of the pipette, and an insemination tip formed at the distal end of the tube, the insemination tip having a diameter less than the diameter of the pipette, the insemination tip having an open ejection port at its distal end and at least one lateral ejection port formed on a lateral side thereof, the tube having seal forming means attached thereto behind the insemination tip; inserting the distal end of the pipette into the tube so that the tube fits over and attaches to the pipette with the insemination tip abutting the distal end of the pipette; guiding the pipette with attached tube and tip into the animal's vagina until the insemination tip is adjacent to the neck of the uterus; forming a seal between the tube and vaginal wall behind the insemination tip with the tip between the seal and the neck of the uterus; ejecting semen from the pipette through the insemination tip in the uterus of the animal.
Claim 7
Independent Claim
188 words
A method of artificially inseminating bovines and similar species, comprising: providing a conventional bovine insemination pipette; providing a rigid tube having a diameter greater than the diameter of the pipette, and an insemination tip formed at the distal end of the tube, the insemination tip having a diameter less than the diameter of the pipette, the insemination tip having an open ejection port at its distal end and at least one lateral ejection port formed on a lateral side thereof, the tube having seal forming means attached thereto behind the insemination tip; inserting the distal end of the pipette into the tube so that the tube fits over and attaches to the pipette with the insemination tip abutting the distal end of the pipette; guiding the pipette with attached tube and tip into the animal's vagina until the insemination tip is adjacent to the neck of the uterus; forming a seal between the tube and vaginal wall behind the insemination tip with the tip between the seal and the neck of the uterus; ejecting semen from the pipette through the insemination tip in the uterus of the animal.
Claim 8
Dependent Claim
27 words
The method of claim 5 wherein the seal forming means is an inflatable balloon, and the step of forming a seal is performed by inflating the balloon.
Claim 9
Dependent Claim
29 words
The method of claim 5 further comprising inserting a speculum into the animal's vagina to locate the neck of the uterus prior to guiding the pipette into the vagina.
