Abstract
Abstract A telescoping speculum has a penetrating tube, a guide tube slidable therein, and a flexible sheath attached to said guide tube adjacent one end thereof and having an attaching member at the opposite end that extends around said penetrating tube. Said sheath is so attached to said two tubes that movement of said guide tube farther into said penetrating tube, causes said sheath along with the latter to penetrate and enlarge a passage in a person''s body to thus prepare it for inspection and medication.
