Описание: Excerpt from The Pneumatic Forceps: Operates in Child-Birth Delivery by Vaginal Dilation, Suction and Grasp; Warranted to Hold More Than Fifty Lbs. To the Vertex With Every Instrument

The change in the neck, the combination in the cup of soft and moderately hardened India rubber, and the circle of notches and depressions, are Still mans improvements in the cup. The cavity of the cup measures in breadth, at the edges, 3 1-10 inches, by 1 inches deep.

When introduced, the dilators should be drawn backwardly and collapsed, the cup ﬂexed so as to bring the edges on a line with the pump; the two edges ﬂattened together by grasp of the thumb and fore finger. The cup being well lubricated upon its exterior surface, with its edges turned upwardly, is easily introduced so that the outer extremity passes readily on the posterior wall of the vagina to the vertex. The thumb and forefinger is then drawn to wards the inner extremity of the cup, allowing the outer to ﬂatten upon the posterior wall of the vagina, until the inner extremity passes behind the pubic arch, and the cup becomes engaged with the vertex.

This is very easily accomplished. A stroke or two of the pump will be necessary to hold it in position, until the dilators are introduced.
