Definitions

  • Heart sounds is heard by stethoscope applied to the chest wall of the patient .
  • Sound waves is transported through the air from the diaphragm to the ear pieces .
  • Time delay milliseconds between occurrence of sound and its hearing .
  • Sounds heard by the manual medical stethoscope may be weak , unclear especially in the presence of additional sounds inside the chest of the patient or in the room surround .
  • Sounds picked by the manual medical stethoscope can not be treated or recorded .
  • Personal computer receive sound waves through advanced sound card .
  • Software is installed to the computer to analyze the heart sound according to its frequency .
  • Heart sounds are plotted as a waves where the vertical line represent the frequency of sound and the horizontal line represent the time .
  • Cardiac lesions can be diagnosed by waves on the screen not only by the sounds heard .
  • Heart sounds can be differentiated from other additional sounds according to the frequency of each sound .
  • Heart sounds can be heard clearly by external speakers with Less time delay .
  • Another sensor is fixed to the cuff of sphygmomanometer to pick the sounds over the brachial artery to have accurate measurement of blood pressure

Abstract

L'invention porte sur un dispositif audio sensible appliqué à la poitrine d'un patient pour recueillir des sons cardiaques. Un ordinateur personnel (6) reçoit les ondes sonores. Un logiciel est installé pour analyser le son cardiaque en fonction de sa fréquence. Des lésions cardiaques peuvent être diagnostiquées par des ondes présentées sur l'écran (7) et pas seulement par les sons entendus. Des sons cardiaques peuvent être enregistrés ou écoutés clairement par des haut-parleurs externes (8) avec moins de temps de retard. Dans cas d'une tachycardie, les sons peuvent être entendus à des fréquences plus lentes. L'enseignement des sons cardiaques sera plus facile. Un autre capteur est fixé au manchon d'un sphygmomanomètre pour capter des sons sur l'artère brachiale.
