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 diamters 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.

La présente invention concerne un dispositif de traitement des plaies en céramique et un procédé permettant de traiter une plaie à l'aide de ce dispositif. Le dispositif de l'invention comprend une pluralité de particules de céramique poreuses inertes séparées qui sont contenues dans un conteneur perméable de type sachet de thé. Les particules de l'invention possèdent une porosité comprise entre 25 et 85 %, de préférence égale à 75 %, et les pores possèdent des diamètres compris entre 0,4 et 30 micromètres. Ces pores sont par nature cellulaires et ils sont reliés entre eux par des cavités. On fabrique les particules de l'invention en pulvérisant un corps céramique microporeux inerte et en enlevant une fine poudre des particules, de façon que les particules présentent un diamètre compris dans une plage qui va de 45 à 300 micromètres.
