How Does Smartho-D2 Digital Stethoscope Help Improve the Auscultatory Precision in the CVD Diagnosis?

Cardiovascular Diseases

Cardiovascular diseases (CVDs) are a group of disorders of the heart and blood vessels. Cardiovascular disease (CVD) is the leading cause of mortality throughout the world, around a third of global mortality per year. More people die from CVD worldwide than from any other cause. Normally, there are no symptoms of the underlying disease of the blood vessels. A heart attack or stroke may be the first sign of underlying disease.

Auscultation of the Cardiovascular System

Auscultation of the cardiovascular system can assist in timely diagnosis of valvular heart disease (VHD), congestive heart failure, and arrhythmias etc., therefore, accurate cardiopulmonary auscultation is crucial to establishing accurate diagnosis. Stethoscope is one of the most powerful tools for CVD diagnosis available to physicians.

However, the diagnostic accuracy of the stethoscope is limited and highly dependent on clinical expertise. And results are limited by significant heterogeneity. Fortunately, with technology advancements changing the world, the stethoscope has moved forward by leaps and bounds.

How does Smartho-D2 Help Improve the Auscultatory Precision

The digital stethoscope Mintti-Smartho-D2 adopts acoustic sensor to convert the analog signal into a digital signal of auscultation, which can realize the storage, hearing and analysis of auscultation signal.

It has changed the condition that the diagnosis of most cardiovascular diseases mainly depends on the doctor’s artificial hearing and improved the diagnostic ability according to the use of weak signal detection technology, acoustic signal analysis technology, and deep learning technology. It can improve the quality of auscultation signal, reduce the environmental noise interference, increase signal amplification by 100 times.

Smartho-D2 digital stethoscope combined with the intelligent terminal at the back end can display the acoustic pathological signal curve on the display screen in real time and highlight the abnormal details so as to realize the visual diagnosis of cardiovascular diseases.

Smartho-D2 digital stethoscope has the ability of signal data storage and wireless transmission. Combined with cloud database, Smartho-D2 digital stethoscope can record and trace back the data information of the patient from the disease at any time, which solves the problem that the stethoscope cannot save the data at present.

At the same time, it is also conducive to the sharing among practitioners. Digital stethoscope Smartho-D2 with cloud database and community platform can realize remote diagnosis, expert online consultation and other services.

At present, Mintti Smartho-D2 has three databases improving diagnostic efficiency and precision, i.e. the pediatric respiratory sound database, the aortic stenosis auscultation database, and the pediatric cardiac sound database for congenital heart disease screening. All of the databases collection has passed the ethics committees, and carried out in the cooperative hospitals.

Furthermore, Mintti Smartho-D2, has not only obtained the NMPA, but also is the first and only one which got both CE&FDA cleared in China.
