Colpometer—device for measuring the diameter of the fundus vaginalis is an instrument for medical use that does not exist on the market and is produced from AISI 420 stainless steel for reuse after autoclave sterilization or produced from polyethylene polymer for disposable use. The device allows measurement of the diameter of the vaginal fornix to enable the medical professional to ascertain said measurement and thus to selected the size of intravaginal component to be used. It has a curved rod with a graduated scale in centimeters that is capable of measuring the distance between the distal ends of the instrument when open. The distance between the open distal ends inside the fundus vaginalis allows verification, using the centimeter scale, of the diameter of the fundus vaginalis. The ovoid distal end thereof allows insertion into the vagina without the risk of unexpected lesions occurring. It provides the appropriate dimensions of the vaginal fornix (FIG. 3-a) up to a maximum of 13 centimeters.
