摘要

1. A medicinal absorbent wad formed from a nonwoven from mainly cellulosic fibres consolidated by fibre entanglement or fusion together with at least one attached X-ray contrast medium formed from a polymeric plastics matrix which is filled with a material which does not transmit X-rays, in which adjacent fibres of the nonwoven are embedded and which contains the absorbent material in amounts of at least 40% by weight, characterized in that the plastics matrix is free from external plasticizers and is composed of linear or crosslinked, non-thermoplastic polyurea, polyurethanepolyurea or mixtures thereof or of crosslinked acrylate polymers and in that the X-ray contrast medium is present on the surface of the absorbent wad in intimate attachment to the fibres thereof.
