Sklar Collin Pelvimeter, 13-3/4in
A 13-3/4 inch pelvimeter used to measure external pelvic dimensions, helping obstetric clinicians assess pelvic adequacy for vaginal delivery.
The Sklar Collin Pelvimeter is a 13-3/4 inch measuring instrument used in obstetrics to take external measurements of the maternal pelvis, providing clinicians with data that can help inform the assessment of pelvic adequacy ahead of labor and delivery. The instrument works on a caliper-like principle, with two adjustable arms that are positioned against specific external bony landmarks so the distance between them can be read off a calibrated scale.
While modern obstetric practice increasingly relies on imaging and clinical judgment for delivery planning, external pelvimetry with an instrument like this remains part of the physical examination toolkit in some obstetric and midwifery settings, particularly where imaging access is limited. Obstetricians, gynecologists and midwives use a pelvimeter as one input among several when assessing a patient's anatomy in relation to expected fetal size and delivery route.
As a metal measuring instrument rather than a cutting or grasping tool, it requires periodic calibration checks in addition to standard cleaning and sterilization between patient uses, ensuring the scale continues to give an accurate reading over its service life.
