Stethoscope is a simple device that is used to transmit low frequency sounds to the ears of the listener. The low volume sounds like heart rate sounds, lungs sounds, intestinal, fetal and venous sounds.
Parts of a stethoscope
Stethoscope is composed of different parts. Following are important parts of stethoscopes.
All these are the soft components that reach both ears. As mentioned earlier, they discover how comfortable you are in general.
The earplugs are made of silicone or rubber and are firmly connected to the ear tubes. For inferior products, headphones usually fall easily or break or break. However, the fantastic news is that most of them contain supplements, in case they fall or fall apart. Excessive tips are generally available in different sizes.
In general, when buying a stethoscope, it is very important to ensure that the selected version contains additional earplugs. This is because your devices will become unusable if the installed devices are removed until you have replaced them.
Hearing tubes are the metal components that connect the main tube to all earplugs.
They are usually made of steel or aluminum and are ribbed at the ends to ensure a perfect fit with all earplugs. In addition, the auditory tubes are bent to match the anatomical orientation of the ears, so that they lean forward and downward to obtain simple auscultation.
The headset consists only of these ear tubes, tip and compression springs. If you have wondered what the springs are, here is a brief explanation.
If you look at a stethoscope image, the two auditory tubes usually intersect in X. This is the job of compression springs, which ensure that the tips remain firmly in the eye during auscultation, putting some strain on the auditory tubes. Remove the two atria, you will find that they provide some immunity and find that your “X-shape” is normal. This happens due to compression springs.
The tube is the elastic part. This can help transmit the sound from the headphones to the headphones.
Some devices have a tube, two others. The double tubes are supposed to have greater acoustic power, but this is not always the case. The presence of two tubes causes another unwanted noise caused by the friction of these two tubes.
The further development of this configuration would be to have two different sound paths (two lumens) in a tube, as the Littmann Cardiology Collection shows.
Due to the robustness of the tube problems, some manufacturers offer tubes that have some immunity to alcohol and body oils. This is crucial because they are a common tool for many health professionals and are often placed on surfaces and unique parts of the human body. The best stethoscope should have some immunity against many fluids and their environment.
The Chest piece is the component that picks up ambient noise (the patient’s epidermis) and transmits it to the tube.
This metal component connects the tube directly to the different parts of the fuselage. Two-headed items are reversible valves that allow you to choose which of these heads to look at for a moment.
The diaphragm is the curved surface of the fuselage, which immediately absorbs vibrations and surrounding sounds. They are available in different materials. For example, Littmann versions have an adjustable ring. This means that the higher the pressure in the upper body during auscultation, the greater the frequency of noise that can be heard, and vice versa.
Some have two diaphragms with the bell-shaped part closed. This generally means that you can enjoy superior sound quality when trying to record lower frequencies with ping pong. For example, if you have to obey the upper body of a young child, you should not look for another device. All you have to do is place the valve on the shaft to start the ringing sound path.

The bell is the largest acoustics in the two-headed units. It is usually lined with a non-cooling case, which can be replaced by a small diaphragm.
It is much better to use the hood when attending thin pediatric patients.
