Antique nickel plated Dieulafoy's Aspirator complete set. Fitted in the original wooden case covered with leather outside and with red velvet linen. Invented by Dr. Paul Georges Dieulafoy (1839-1911), this instrument is used primarily for drainage of pleural effusions or ascites, but occasionally applied for many other different uses. It differs from Potain for the piston controlled by a screw system and the large glass cylinder. Dated end of 19th century. Case size 24x11x5 cm.
