Abstract

Abstract A method and instrument for placing an implant in the teat duct and udder of an animal, as a milk cow. The instrument has an elongated tubular member having a passge accommodating the implant. The tubular member is adapted to be inserted into the milk duct through the discharge end thereof. A head having finger gripping ears is attached to the tubular member. The implant is moved from the passage with a piston connected to a rod extended through the head. A head engaging member secured to the rod is used in cooperation with the ears to apply force to the rod to move the piston in the passage to move the implant into the teat duct and udder. The implant has a core of an elongated flexible plastic string. A plurality of bands are clamped about the core. Alternate bands are coated with a first metal, as silver. The remaining bands are coated with a second metal, as gold. All of the bands may be coated with the same metal, such as silver. The implant includes a capsule implant containing material that reacts with the silver to produce silver ions which have advantageous antibacterial effects.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 69 words
A method of inhibiting mastitis in the udder and teat canal of a bovine animal comprising: locating metallic silver in the udder of a bovine animal, leaving said metallic silver in said udder whereby silver ions originating from said metallic silver provide micro-organism control with the udder, and introducing a sulphur compound into said udder, said sulphur compound reacting with said metallic silver to produce anti-bacterial and anti-virus substances.
Claim 2
Independent Claim 69 words
A method of inhibiting mastitis in the udder and teat canal of a bovine animal comprising: locating metallic silver in the udder of a bovine animal, leaving said metallic silver in said udder whereby silver ions originating from said metallic silver provide micro-organism control with the udder, and introducing a sulphur compound into said udder, said sulphur compound reacting with said metallic silver to produce anti-bacterial and anti-virus substances.
Claim 3
Dependent Claim 23 words
The method of claim 1 wherein: said core and metallic silver associated therewith are located in the udder cavity adjacent the teat canal.
Claim 4
Independent Claim 86 words
A method of inhibiting mastitis in the udder and teat canal of a bovine animal comprising: locating a metal in the udder of a bovine animal, said metal characterized as being the type that will liberate metal ions that have effective micro-organism control within the udder, leaving said metal in said udder whereby the metal ions originating from said metal control mastitis in the udder, and introducing a sulphur compound in said udder, said sulphur compound reacting with said metal to produce substances that treat mastitis.
Claim 5
Independent Claim 86 words
A method of inhibiting mastitis in the udder and teat canal of a bovine animal comprising: locating a metal in the udder of a bovine animal, said metal characterized as being the type that will liberate metal ions that have effective micro-organism control within the udder, leaving said metal in said udder whereby the metal ions originating from said metal control mastitis in the udder, and introducing a sulphur compound in said udder, said sulphur compound reacting with said metal to produce substances that treat mastitis.
Claim 6
Dependent Claim 22 words
The method of claim 3 wherein: said core and metal associated therewith are located in the udder cavity adjacent the teat canal.
