Speculum, upper blade
This curved, hollow metal blade, part of a speculum, is termed the upper blade. See also Speculum, lower blade (Object 1202).
A speculum tube (from Latin speculum: “mirror”) is a medical instrument for gynaecological examinations. This tube is gently inserted into the vagina to provide a view into it and into the neck of the uterus.
With the aid of a speculum tube, other instruments can be inserted through the cervix and into the uterus in a sterile environment.
