A teat cautery bullet or device for insertion through the teat orifice and into the papillary duct of an injured teat of a dairy cow or similar animal to control hemorrhaging and prevent formation of a blood clot in the teat orifice or papillary duct is formed by molding of solid material which is soluble by liquid in said teat to control such hemorrhaging and clotting. The device comprises a nose portion tapered to facilitate insertion, an integral neck portion tapered to facilitate retention, and an integral base portion to facilitate insertion and removal and of such width as to prevent passage or loss of the device upward into the teat sinus. The soluble material of which the device is molded may consist entirely of one or more soluble active ingredients, such as ferric ammonium sulfate, aluminum ammonium sulfate or aluminum potassium sulfate or may consist of a soluble mixture of one or more of the aforementioned soluble active ingredients and one or more soluble inert binder ingredients, such as amylon, amylum or amylopectin or other starches, which affect the consistency and the solubility of the device. In use, the internally disposed nose and neck portions dissolve before the externally disposed base portion and loss of the device into the teat sinus is prevented.
A teat cautery bullet shaped device for insertion through a teat orifice and into the papillary duct of an injured teat of a dairy cow or similar animal to control hemorrhaging and prevent formation of blood clots in the papillary duct, said device being formed of solid material having astringent and styptic qualities which is soluble by liquid in said teat to control such hemorrhaging and clotting, said device comprising a nose portion shaped to facilitate insertion, an integral neck portion shaped to facilitate retention by the teat sphincter muscles surrounding said papillary duct, and an integral base portion shaped to facilitate manual insertion and removal and to prevent passage or loss of the device upward into the teat sinus.
A teat cautery bullet or device of generally circular transverse cross section for insertion through a teat orifice and into the papillary duct of an injured teat of a dairy cow or similar animal to control hemorrhaging and prevent formation of blood clots in said papillary duct, said device being formed of solid material having astringent and styptic qualities which is soluble by liquid in said teat to control such hemorrhaging and clotting, said device comprising a nose portion tapered to facilitate insertion, an integral neck portion at least as long as said papillary duct and tapered to facilitate retention by the teat sphincter muscles surrounding said papillary duct, and an integral base portion shaped to facilitate manual insertion and removal and wider than said nose portion and said neck portions to prevent passage or loss of the device upward into the teat sinus.
