Ceramic wound treatment device.
Abstract
This invention relates to a ceramic wound treatment device and to a method of treating a wound using such device. The treatment device comprises a plurality of separate inert porous ceramic particles which are contained in a permeable tea-bag type container. The particles have a porosity of between 25% and 85% preferably 75% and the pores have diameters in the range of between 0.4 to 30 micrometers. The pores are cellular in nature and are interconnected by blow-holes. The particles are manufactured by pulverising an inert microporous ceramic body and removing fine powder from the particles, such that the particles have a diameter range of between 45 and 300 micrometers.
