Dieulafoy-type aspirator, England, 1870-1910

Aspirators were used to draw out and remove substances from the body such as mucus, serum and infections. A trocar is inserted into the body, allowing a cannula, a tube used for drainage, to be inserted. The cannula is attached to the screw-operated piston by rubber tubes. The handle of the pump is then pulled up, sucking out the substances. This kit comes with three trocars, three cannulae and four aspirating needles, all different sizes for various parts of the body. However, aspirators declined in use with the rise of aseptic surgical techniques. Georges Dieulafoy (1839-1911), a French physician and pathologist, invented this type of aspirator in 1869.
