Abstract
An improved method and apparatus is disclosed for adding fluids to, or removing fluids from, a body part or organ of an animal which minimizes animal trauma and permits rapid, easy, repeated fluid or low viscosity gels transfers. The apparatus includes a valve assembly having a tubular fluid-conveying element adapted for fixed connection to the animal, along with a fluid conduit connected between the valve element and a specific internal body part or organ, such as a cow's uterus. In use, a syringe is employed to introduce or remove fluids from the body part, through the valve assembly and connected conduit. The invention is especially adapted for introducing, recovering cell lines producing monoclonal antibodies or other biologically active products in large mammals, and facilitates monitoring of antibody production as well as administration of nutrients to enhance cell line growth.
