Abstract
Abstract A surgical sponge comprises a bulbous jacket of at least two superimposed inside and outside lying separate cuts of about the same length, of which the outside cut consists of a gauze material, the superimposed cuts having their edge portions gathered together to form a constricted inturned tubular neck, a rubber ring disposed interiorly of the jacket and contracted onto the inturned neck. The inside lying cut includes of a soft flat fleece of high absorbency, whereby the sponge can be mechanically produced, and is completely homogeneous, soft and nestling and especially the rubber ring is upholstered at its outer side by the soft fleece material. The sponge is free of loose threads and lint and resistant even in moist condition.
