ABSTRACT:
A girth measuring device for making simultaneous multiple measurements of the girth of an elongate portion of a body along its length has a generally rectangular base member adapted to be placed along the elongate portion of the body being measured and has index marks along one longitudinal side. A series of longitudinally spaced spring wound flexible measuring tapes on the base member extend and retract relative to the base member. A drawbar at the outer ends of the measuring tapes allow them to be simultaneously extended from their retracted position and placed in encircling relation about the body portion being measured. The drawbar is removably engaged on the base member to position the calibrations of the measuring tapes over the index marks. The girth measuring device allows measurements to be taken of each tape to determine the girth of the body portion being measured at longitudinally spaced locations along its length. One end of the base member may be configured to reside closely adjacent to a bone structure or joint adjacent to the body portion being measured whereby subsequent measurements are made at substantially the same longitudinally spaced locations. The spring tensioned measuring tapes firmly conform to the contour of the body portion being measured and subsequent measurements are consistently made with the same amount of tension.
