Indian Institute of Technology of Bombay (IIT-B) has developed a digital stethoscope. This stethoscope can listen to heart beats from a distance and can record them. this will mainly use in the field of COVID-19 patients so that the minimising the risk of healthcare professionals contracting of coronavirus.
The data or the auscultated sound from a patient’s chest is wirelessly sent to the doctor using Bluetooth, and that data will be measured and record by the team. the record will be mention in the patient health record book. and be examined and can be shared with the other doctors too.
Operating a start-up called “AyuDevice” from the IIT’s technology business incubator, this IIT Bombay team has sent 1,000 stethoscopes to different hospitals and healthcare centres across the country.
Giving details about the digital stethoscope, Adarsha(one of the developers) said it “consists of a tube connected to two earpieces. The tube transmits sounds from the body while eliminating background noise that might interfere with diagnosis“.
Adarhsa K also said “Patients diagnosed with coronavirus often experience shortness of breath, leading to acute respiratory distress syndrome. Doctors use (traditional) stethoscope to listen to chest sounds such as wheezing and crackles that appear with the progress of the disease,”
“The second advantage is that the stethoscope is able to amplify and filter several sounds and translate them into an electronic signal, which can be further amplified for optimal listening,” he said
“The signal can then be displayed as a phonocardiogram on a smartphone or laptop. In contrast, a regular stethoscope is limited when it comes to amplifying sounds and there is no way of recording those sounds and sharing from one place to another. Even visualisation is not possible, which means one cannot see the graph and identify abnormalities,” said by Adarhsa
