Title
(EN) CALCIUM SULFATE HEMIHYDRATE COMPOSITION HAVING UTILITY IN THE PRESENCE OF BLOOD
(FR) COMPOSITION A BASE D'HEMIHYDRATE DE SULFATE DE CALCIUM UTILISABLE EN CONTACT AVEC LE SANG
Abstract
(EN)
Calcium sulfate hemihydrate can be combined with calcium sulfate dihydrate to provide a composition capable of hardening in the presence of blood. The dihydrate can be added to the hemihydrate as a separate ingredient or by forming it on the hemihydrate in situ during the manufacture of the hemihydrate. An organic or inorganic material such as calcium phosphate material, which may be either resorbable or nonresorbable by body fluids, can be mixed with the hemihydrate material prior to contacting it with a wetting agent. In a preferred method, the calcium sulfate hemihydrate composition containing the calcium sulfate dihydrate is contacted with a wetting agent to initiate the hardening reaction which proceeds for a brief period of time prior to any contact with blood or similar proteinaceous material.
(FR)
L'hémihydrate de sulfate de calcium peut être combiné avec un dihydrate de sulfate de calcium pour obtenir une composition capable de durcir après mise en contact avec le sang. Le dihydrate peut être ajouté à l'hémihydrate comme un ingrédient séparé ou en le formant sur l'hémihydraté in situ pendant la fabrication de l'hémihydrate. Une matière organique ou inorganique telle que le phosphate de calcium, qui peut être résorbé ou non par des liquides organiques peut être mélangé avec la matière hémihydratée avant sa mise en contact avec un agent mouillant. Dans une méthode préférée, la composition à base d'hémihydrate de sulfate de calcium contenant l'hémihydrate de sulfate de calcium est mise en contact avec un agent mouillant pour entamer la réaction de durcissement qui se poursuit pendant une courte période de temps avant tout contact avec le sang ou toute matière protéinique.
