The Chestpiece of A Stethoscope
Apparently, the chestpiece of a stethoscope is one of the most crucial parts of a stethoscope. Although all aspects and parts of the instrument are very essential and important as they have their own roles to play, the chestpiece is actually the first line of defense in every stethoscope.
As it happens, the chestpiece is the main part that is responsible for capturing the sounds. So, it is considered to be the first part that works when a stethoscope is being used by either a doctor or a nurse.
As you may know, stethoscopes are devices that are mainly for auscultation. And whether it may be for the lungs or the heart (or even other parts of the human body), stethoscopes will help the medical professionals to listen to the sounds of your body.
Certainly, you already know how stethoscopes work in general. And as everyone would recall it, the first thing that any doctor or nurse would do when using them is to apply the head of the stethoscope over the skin of the patient. Well, obviously, this is aside from wearing the stethoscope and plugging the earpiece onto the ears of the user.
Now, the head that is being applied on the skin is basically the chestpiece. Accordingly and as mentioned, this aspect is the one responsible for capturing the sounds. In short, this is where everything starts when a stethoscope functions. So, it is very essential to have a very effective and efficient chestpiece.
Types of A Chestpiece
Normally, there are two types of a chestpiece. As mentioned in the previous portion, users can choose between the single type and dual type. Although it is considered that there are technically three types, the third one largely falls under the digital types or the electronic stethoscope. Hence, most people would already exclude this type when tackling about the conventional chestpiece.
Single Head Stethoscopes
A singe head stethoscope is basically a chestpiece that has only a diaphragm. Hence, the users can only use one side of the chestpiece. Typically, this kind of stethoscope is used for medium frequency of sounds. And since it only offers one side of the chestpiece, the functionality is very limited.
Nevertheless, there are still great single head stethoscopes that can compete with the other type. However, these instruments are not very recommendable for critical applications and uses. And as it appears, they are much more ideal for assessments and other physical test purposes only.
Also, they are seen to be ideal for sphygmomanometer uses.
Dual Head Stethoscopes
As for the dual head stethoscope, this instrument is very versatile. This is because the chestpiece offers both sides of the head. The side that has the larger diameter and area is called the diaphragm while the other side or the smaller one is also known as the bell.
The diaphragm is largely for high frequency of sounds. Conversely, the bell is for lower and more focused frequencies of sound. So, the users can typically change sides while using the stethoscope.
More often than not, stethoscopes that are designed for critical uses and purposes are the duel head types.
