ABSTRACT
The motive of this paper is to digitalize the stethoscope to improve its utilization and provides accurate measurement of heart beat and frequency rate. This work also contributes to predict the abnormality of a patient heart beat with the aid of a Light Emitting diode (LED) which flashes the corresponding heart-beat, frequency rate and the status of the patient denoting normal/abnormal. The present condition of the patient can also be shared with the physician through a smartphone. The status of the patient is thereby recorded and can send to the physician to enhance the treatment of the patient who is in an abnormal condition. The sound energy sensed by the stethoscope is converted to its corresponding electrical energy, which in turn flashes in the LED alphanumeric display unit. The normal and abnormal of the heart beat discrimination is performed by using an Embedded C coding fired in the display unit. Hence, whenever the heart beat is within the preset value, it denotes normal and contrarily when it crosses the preset value the LED display flashes as an abnormality. This user-friendly modified stethoscope will find applications for patients residing in remote hill stations and for physically challenged patients.
