Abstract (en)
[origin: CA2297752A1] An instrument for measuring a dilatation of cervix uteri during a first stage of labor. The instrument includes two arms (1, 2) pivotally connected together, with two finger loops (9, 10) on one end and a scale (8) on another end of one of the arms. The scale has transversely spaced graduation marks. An indicating tip (7) is provided at the other end of the other arm which moves relative to the marks when the loops are moved relative to each other to palpate an edge of an orifice or cervix uteri. The tip and/or the scale have cooperating fixing structures (14) for temporarily fixing the position of the tip relative to the scale so that even if the fingers are moved when the instrument is removed the measurement is not lost.
