ABSTRACT:
A meter (10) for measuring cervical dilation during labor includes rings (20 and 22) that fit at the bases of the user's fingers (24 and 26). Pivot arms (14 and 16) mount the rings (20 and 22) at one end and a scale and indicator (30) at the other end. Scale indicia indicate the separation of the rings. Ring separation can be translated into the separation of the finger tips and thus into cervical dilation.
