| 摘要 |
The present invention includes methods and apparatus for depositing materials in the reproductive tract of an animal, such as antibiotics or semen for artificial insemination, using an improved device that covers the end of a sheath inserted into the reproductive tract. A thin protective membrane is provided at the tip of the sheath having a tiny pre-ruptured prick opening therein that is designed to rupture under increased pressure from the fluid inside the sheath. The protective cover can be an integrated portion of the sheath itself, or a material applied to the tip of the sheath. The protective cover is minimal in size as to not increase the diameter of the sheath so that there is no loss in tactile sensitivity to a physician or breeder who must maneuver the invention through the reproductive tract of the animal.
