| مستخلص: | A disposable uterine sound device is described for measuring the depth and course of an uterine cavity. The device is formed by coating a copper rod and a portion of an attached nylon handle with polyvinyl chloride. The coating is then printed with a generally nonleachable biocompatable ink to form graduations indicating units of measure of length. The resulting device is a flexible, smooth service device which minimizes trauma to a patient during use. |
