The number of COVID-19 cases is rising in India and there are many reports that the health workers are also getting infected with the Novel Coronavirus due to the lack of Protection gear in the country.
A team of researchers at the Indian Institute of Technology, Bombay (IIT-B) has developed a ‘Smart Stethoscope’ that can record the heartbeat of patients from a distance making it safe for the patient and doctors to minimize the risk of getting infected. The device has been developed with clinical inputs from doctors at Reliance Hospital and PD Hinduja Hospital.
When in use the data or the auscultated sound from a patient’s chest is wirelessly sent to the doctor using Bluetooth, doing away with the need to go near to take readings, as told by the members of the team.
The research team has sent 1,000 such stethoscopes to different hospitals and healthcare centers across the country operating as a startup “AyuDevice” under the IIT’s Technology business incubator.
“Patients diagnosed with Novel Coronavirus often experience shortness of breath, leading to acute respiratory distress syndrome. Doctors use the (traditional) stethoscope to listen to chest sounds such as wheezing and crackles that appear with the progress of the disease,” one of the developers Adarhsa K said.
This, however, poses a risk to doctors, as evident from the rising infections reported among healthcare professionals handling COVID-19 patients, he said.
Providing some details about the Smart Stethoscope, Adarsha 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”.
“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 visualization is not possible, which means one cannot see the graph and identify abnormalities,” he added.
As of writing this, the country has 7,367 active cases, 715 cured, 273 deaths. More details here
