FIELD OF THE INVENTION
Our Invention is related to a PROVIVE DIGITAL STETHOSCOPE

BACKGROUND OF THE INVENTION

An electronic stethoscope having a vibration transducer, a speaker, an earphone plan, and something like one computerized channel for laying out no less than one motivation move capability relating to no less than one acoustic stethoscope type.

In this manner, the signs heard will relate to those learned, and subsequently the upsides of more prominent enhancement and disposal of clamor sources might be completely used. The capacity to make up for a singular specialist's hearing misfortune is empowered.

Moreover, with stereoscopy exemplifications, sound recurrence conveyances can be changed to spatial or worldly sound appropriations discernible by the client working with, for instance, the location of heart mumbles and the taking of circulatory strain.

PRIOR ART SEARCH
CN104287772A: The invention discloses a digital stethoscope. The digital stethoscope is composed of earpieces, a sound pick-up, an intelligent mobile terminal (a smart phone or a PAD), an audio signal line, a left sound production unit and a right sound production unit, wherein the earpieces are used for converting vibration into sound, the pickup is used for converting sound into an electrical signal, and the intelligent terminal is used for digitizing the electrical signal, displaying a digital signal on a screen of the smart phone and outputting an audio signal.

The left sound production unit and the right sound production unit. The front-end hardware (the earpieces and the sound pick-up) are used as sensors for collecting a sound signal (heart sound, lung sound and the like) of a body, the sound signal is converted into the electrical signal through an audio port of the mobile phone, the signal is subjected to Fourier transform to obtain a frequency-domain signal, and an obtained time signal and an obtained frequency signal are displayed on the screen for quantitative analysis by a doctor. At the same time, the intelligent terminal outputs the audio signal through the earpieces in real time.

EP2110080A1: The preamplifier performs impedance conversion. A pre-emphasis takes place in the first amplifier. The pre-emphasized signal is fed to the digital filtering unit. The digital filtering unit comprises an analog-to-digital converter (A/D converter), a digital filter, and a digital-to-analog converter (D/A converter).

A switch selects either the filtered signal from the filtering unit, or a direct signal from the preamplifier, in order that a comparison may be made between the filtered signal and the unfiltered signal, by switching these two signals. Before such a comparison is performed, there may be loudness equalization between the two channels so that the ear will not have too great adjustment problems by the comparison. From the output amplifier, the amplified signal is brought to one or several headphones.

OBJECTIVES OF THE INVENTION

1. The objective of the invention is to provide a Stethoscope for listening (auscultation) and interpretation of the sounds of heart and lungs as claimed in claim 2 wherein the filter section is built with a band pass filter circuit having the frequency range of most HS signals.
2. The other objective of the invention is to provide a Stethoscope for listening (auscultation) and interpretation of the sounds of heart and lungs as claimed in claim 3wherein a digital filter is used to extract the signal within the frequency band of interest from the noisy data.
3. The other objective of the invention is to provide a Stethoscope for listening (auscultation) and interpretation of the sounds of heart and lungs as claimed in claim 4 wherein advanced artifacts removal is used for output signal-to-noise ratio (SNR) improvement.
4. The other objective of the invention is to provide a Stethoscope for listening (auscultation) and interpretation of the sounds of heart and lungs as claimed in claim 5 wherein processor carries out the Signal processing to convert the raw data into presentable data for further analysis.
SUMMARY OF THE INVENTION

Stethoscopes are utilized by doctors to pay attention to sounds from the life form, specifically heart and lungs. The peculiarities tuned in for produce sounds with frequencies from under 16 Hz to around 8 kHz, yet a serious low pass sifting happens during the entry of tissue and skin. The skin behaves like a transmitter of those signs which are hence open.

The development of the stethoscope discovers that main a little region of the skin is paid attention to at a time, and that sounds in the room outside are hosed, and in this way, the sign to-clamor proportion is to some degree gotten to the next level. Doctors train effectively in the utilization of stethoscopes, and subsequently their capacity to recognize signals in the encompassing commotion might ascend by around 15 dB.

This happens the world over, and it could be said that a stethoscope is a widespread device. In any case, it’s worth or potentially execution to the clients have fallen, because of the specialized advancement of society. The expanded machine clamor, specifically in emergency clinics, by and by, makes the signs lie underneath, or at the most at, the lower furthest reaches of human hearing.

To this might be added that increasingly more youngster's experience the ill effects of hearing misfortune at the time they might leave on a clinical training, and subsequently the acoustic stethoscope has by and by arrived at its constraint of execution.

DESCRIPTION OF THE INVENTION
the patient wherein said stethoscope comprises of chest piece with diaphragm to collect the vibrations with the help of microphone or piezoelectric sensors; the sound signals from the heart are converted to analog electrical signals by the analog-to-digital converter; a pre-amplifier with a small gain is used to suppress the interference from power lines; further pre amplifier transmits these signals to power amplifier; an anti-aliasing filter is then employed to prevent aliasing effect.

A Stethoscope for listening (auscultation) and interpretation of the sounds of heart and lungs as claimed in any of the claims wherein the device can be connected to any application and with the help of the same the practitioner can listen, monitor and even record heart and lungs sound remotely.

The concept behind multiple headphones connected with our stethoscope is that It helps the students to listen to live heart and lungs sound when their professor places the stethoscope on patient’s chest and students and their professor both listen to the sound simultaneously and the professor will explain the sound so students can understand better.

A Stethoscope for listening (auscultation) and interpretation of the sounds of heart and lungs as claimed in any of the claims wherein output signals through wireless personal area network can be shown over any display unit.
