ABSTRACT:
The invention concerns sleeves for protection against internal contaminations for a gynaecological gun for animals of the type comprising a tubular body, a chamber for storing the product to be injected or aspirated, and ejecting or aspirating means (7) operative through the front end of the body. The problem is to avoid contaminations through the medium of the gun between the vagina and the uterus of the animal.
According to the invention, such a sleeve comprises a cylindrical element (13) of flexible and thin material and having an end (13c) which is closed in a sealed manner but is tearable, the length of the sleeve approximately corresponding to the length of the whole of the gun, two substantially parallel slits (16) being provided in the vicinity of the end (13a) opposed to the closed end.
The invention is advantageous in the artificial insemination of bovines.
