ABSTRACT:
An elongated speculum blade for insertion horizontally into the vagina of a standing animal. From an end of the blade a balancing weight extends adjustably vertically downward and adjustably horizontally under the blade, enabling the speculum to be self-supporting. With this blade in place, a second blade may be inserted and freely moved to observe particular regions in the vagina.
