Automotive digital stethoscope

The stethoscope, also called phonendoscope, is a medical device used to perform auscultation, a clinical procedure that consists of listening to the internal sounds of the rib cage and abdomen in search of sounds that may indicate any pathology in the trunk organs.The stethoscope is one of the most widely used tools in general medicine and is traditionally considered an icon of the medical profession. Nowadays, the development of other technologies, especially the advance of ultrasonography, is displacing the use of the stethoscope, although it is not likely to be totally relegated in a long time.Table of Contents

What is the digital stethoscope?

The electronic stethoscope allows the auscultation sounds to be heard clearly. It is beneficial for the physician’s diagnosis both in the case of faint sounds and in the case of physicians with hearing loss.

What is the stethoscope and what is it used for?

The stethoscope is an acoustic device that amplifies body noises to achieve better perception and therefore the integration of various signs, which are mainly auscultated in the heart, lungs and abdomen and are part of the semiology of General Medicine to the various specialties.

What are the advantages of using a stethoscope?

#2 Amplifies cardiac and/or respiratory sound.

Facilitates diagnosis in case of sounds imperceptible to the health professional, making a clear and defined listening. Enhances weak sounds. Helps professionals with hearing loss in their diagnosis.

On top of that, you have the software with AI algorithms that analyze those sounds, translate and deliver in the form of digital data for both parties: doctor and patient. The StethoMe algorithms indicate and inform patients about possible abnormalities appearing in their respiratory system. Then, a physician receives the sound waves in real time in his or her system, with indicators of all those anomalies.

Our AI algorithms are based on 12,000 recordings, 40,000 medical descriptions and more than one million medical categories, which are generally used to classify the waves and their attributes. For the patient it works as follows: you follow a simple, step-by-step tutorial to do auscultation correctly at home. Then, StethoMe’s AI analyzes the sounds obtained and delivers immediate results. There are three possible answers: green, orange or red lungs. Green means that everything is fine, orange shows that some anomaly has been detected and red indicates that there may be a more serious problem. With this information, you can send the complete results to a doctor, who will receive precise information about possible anomalies or problems.

What is a stethoscope and its parts?

It consists of one or two rubber tubes that end in two ogives that adapt to the ear and also these tubes are linked to another tube containing a diaphragm (also called membrane) and a metal bell which amplify the auscultation sounds.

What is the name of the device used to listen to the heartbeat?

When you go to the doctor, he or she will probably use a device called a “stethoscope” to listen to the sounds your body makes. Usually, we can’t hear these sounds very well, but with the help of a stethoscope it is possible to magnify them a great deal.

What is the name of the device for listening to the lungs?

Auscultation is usually performed using an instrument called a stethoscope. Health care providers routinely listen to a person’s lungs, heart, and intestines to evaluate these characteristics of sounds: Frequency. Intensity.

Digital stethoscope

The research published in Joseph Skoda’s “Treatise on Percussion and Auscultation” (1839) gave this nosological sign a remarkable clinical and scientific pragmatism, which has survived to the present day.

It is constituted by one or two rubber tubes that end in two ogives that adapt to the ear and in addition these tubes link with another one that contains a diaphragm (also called membrane) and a metal bell which amplify the auscultation sounds.

To listen to low frequency sounds, rest the stethoscope on the patient’s skin without pressing. The membrane is held by a flexible contour suspended on the membrane, allowing the membrane to vibrate widely and transmit long wavelength sounds, i.e. low frequency sounds.

To pick up the higher frequency sounds, it is pressed firmly, in the same way as a traditional double bell stethoscope in diaphragm mode. When this pressure is exerted, the membrane moves inward until it touches an inner ring. This ring restricts the movement of the membrane by blocking or attenuating the longer wavelengths of the low-frequency sounds, allowing only the shorter wavelengths of the high-frequency sounds to be heard.[8]

What can be heard with the stethoscope?

Using a stethoscope, the physician can hear normal breath sounds, decreased or absent breath sounds, and abnormal breath sounds.

How is the stethoscope used?

You must place the phonendo in such a way that the olives are introduced into your ears, following the direction of the ear canal. That is to say, as if the olives were facing our nose, from posterior to anterior.

Who uses a stethoscope?

This stethoscope is used by the physician for auscultatory examination at the carious, pulmonary and abdominal levels, looking for murmurs, the patient’s blood pressure, crackles and snoring.
