International ClassA61B 017/42AbstractA digital amniotome with a directional indicator, having an elastomeric finger sheath configured to fit over a user's finger, and a membrane rupturing unit having a sharp-tipped element extending from a base. The sharp-tipped element is directionally oriented, such that it has a cutting edge for rupturing an amniotic membrane and a smooth edge. In one embodiment, the base is secured to the interior surface of the distal end of the finger sheath such that the sharp-tipped element passes through the opening in the distal end of said finger sheath. The base and/or the opening of the finger sheath are shaped to facilitate visual identification of the directional orientation of the sharp-tipped element. The finger sheath is color contrasted with the base to further facilitate visual identification of directional orientation of the sharp-tipped element. In another embodiment, the base is secured to the distal end of the finger sheath at its exterior surface, and the base is shaped to provide visual identification of the directional orientation of the sharp-tipped element. | |
