Abstract

L'invention se rapporte à un appareil pour la détermination des paramètres d'élasticité du sang. L'appareil comporte un cylindre 7 destiné à être immergé dans un conteneur 6 de sang, soumis à des oscillations régulières; le cylindre 7 est rigidement fixé à un châssis 8 oscillant selon un axe vertical et mécaniquement relié à un dispositif électro-magnétique 14, 15, 16, qui engendre une force de réaction; le châssis 8 est en outre relié à un transducteur électro-magnétique linéaire 19 destiné à fournir des signaux à un appareil d'enregistrement. Application de appareil à la thrombo-élastographie.
