Patent ID: 10182896

Abstract:
The present invention provides an artificial insemination apparatus and methods for use with livestock that maintains the sterility of the semen until it is deposited at an optimum location in the reproductive tract of the animal without the maneuvering or tissue injury problems associated with prior art devices. Embodiments of the present invention comprise a uniquely shaped opening that is provided at the tip of a sheath that is used with an artificial insemination gun, and a movable or deformable plug or diaphragm that fits into and covers this opening. The plug or diaphragm has a rounded (convex) exterior surface, and may be made of a rigid or rubberized material that completely covers the opening at the tip of the sheath, and seals it closed in a smooth, flush engagement to prevent contaminants from collecting upon the tip, or entering into the sheath during the trip through the reproductive tract of the animal. Once the sheath is properly placed in the reproductive tract, application of fluid pressure to the semen inside the sheath causes the plug to move or deform without becoming detached from the sheath, thereby allowing semen inside the sheath to exit. In alternative embodiments, the unique tip with its opening and corresponding plug may be provided in a separate cap that is installed at the end of an insemination sheath.
