Abstract

La présente invention décrit un appareil destiné à mesurer grâce à une technique non invasive la masse osseuse, ledit appareil étant doté d'une plate-forme destinée à soutenir l'os à mesurer, d'un ressort d'une rigidité donnée, qui relie la plate-forme à un capteur capable de mesurer la vitesse et la force de vibration, et d'un vibreur relié au capteur. Ledit vibreur fait subir des vibrations au capteur, au ressort et à la plate-forme. Le capteur peut ainsi mesurer la vitesse et la force de ces vibrations, ce qui permet de déterminer la masse osseuse. La présente invention décrit également un deuxième appareil permettant de déterminer par technique non invasive la masse osseuse. Cet appareil est doté d'une pince, d'un ressort d'une rigidité donnée, qui relie la pince à une plate-forme destinée à positionner l'os à mesurer, d'un capteur capable de mesurer la vitesse et la force des vibrations, qui relie la plate-forme à un vibreur et d'un vibreur qui fait vibrer le capteur, la plate-forme, le ressort et la pince de façon à permettre au capteur de mesurer la vitesse et la force de vibration. La présente invention décrit en outre un procédé visant à déterminer de façon non invasive la masse d'un os à l'aide des appareils ci-dessus.
