Definitions

  • hemorrhage in traumatized casualties remains the major cause of death in combats.
  • a rugged device to assess overall hemostasis function in forward combat areas is thus strongly desired.
  • perioperative diagnosis and monitoring of blood coagulation is critical to better understand the causes of hemorrhage, to guide hemostatic therapies, and to predict the risk of bleeding during the consecutive anesthetic or surgical procedures.
  • a timely informed blood coagulation assessment is critically needed in determining patient susceptibility to postoperative thrombotic complications or as indicator of early sepsis, particularly regarding the use of blood products and guiding treatment with haemostatic components .

Abstract

L'invention concerne un dispositif d'élastométrie à détecteur magnétique (MSED) et un procédé de réalisation d'un dosage par thromboélastographie de sang complet. Il contient des éléments clefs, comprenant une cuvette à échantillons, une tête de détection, un disque rotatif, un détecteur de mouvement optique, etc. ; et mesure la viscoélasticité des échantillons de sang complet. Le dispositif surveille optiquement le mouvement physique du disque rotatif entraîné magnétiquement, immergé dans l'échantillon de sang. Le thromboélastographe est enregistré par le détecteur de mouvement optique lisant des coups de hautes impulsions, passant à travers le disque rotatif, via une fenêtre temporelle à porte. Le dispositif comporte également un microcontrôleur et son microprogramme intégré pour réaliser les fonctions d'entraînement du disque magnétique rotatif, de génération d'impulsions à hautes fréquences, de commande de la fenêtre temporelle d'impulsions de données, ainsi que de maniement de l'interface utilisateur, d'analyse des données et de maintien de la communication avec un ordinateur externe.
