DEVICES AND METHODS FOR MEASURING CERVIX OF UTERUS Russian patent published in 2015 - IPC A61B5/107 A61B1/303 

FIELD: medicine.

SUBSTANCE: invention relates to medical equipment, namely to instruments for measuring length of cervix of uterus in vaginal vault and cervix of uterus dilation. Device for measuring cervix of uterus length contains elongated measuring unit, hollow unit, flange, handle and lock mechanism. Elongated measuring unit extends along longitudinal axis and includes measuring scale located on it. Hollow unit is coaxial with elongated measuring unit and is located above it. Flange is displaced from longitudinal axis and is fixed to distal end of hollow unit. Handle is fixed to proximal end of measuring unit. Lock mechanism is made on handle. Lock mechanism is made with possibility to fix hollow unit relative to measuring unit in case of blocking, and in case of de-blocking to provide possibility for hollow unit to slide along measuring unit and to rotate around longitudinal axis in such a way as to place flange in required position of rotation without moving measuring scale. Proximal end of hollow unit is made with possibility of sliding in handle.

EFFECT: invention provides simplicity, ease and accuracy of performing measurements.
