A French physician René-Théophile-Hyacinthe Laënnec in 1819 explained the perforated wooden cylinder that transmits the sound from the human’s chest to the physician’s ears, later evolved into the convenient form of a modern stethoscope. Best Stethoscope For Doctors & Nurses in 2023? A stethoscope is a medical instrument used to hear the sound produced inside the human body. This is mainly used to hear the sound created in the chest and the sound from the heart which is a heartbeat.
Initially, a monaural stethoscope was made, later supplanted by a binaural type with two flexible rubber tubes attached to the chest part and spring-attached metal tubes to the ears. In recent days the stethoscope with two chest pieces is widely used. One chest piece is bell-shaped and open-ended to transmit low-pitch sound while the other is flat and covered with a semirigid disc to hear high-frequency sound. By turning the valve both chest pieces can be used alternatively.
As everyone knows that nurses shouldn’t wear any ornaments or decorative accessories when they are on duty for safety concerns. This stethoscope charm might satisfy the desire of the nurse to wear jewelry. Typically stethoscope charm is a small decorative ornament wrapped around the tubes of the stethoscope like a bracelet. Depending on their preference, the nurse can add one charm or a string of a few charms that coordinate with the entire design.
The word electronic and digital is used interchangeably to refer to the same stethoscope. So electronic stethoscopes and digital stethoscopes mean the same.
An acoustic signal will be converted by a digital stethoscope to an electrical signal that may then be amplified for ideal listening. To convey this electronic signal to laptops, it must first undergo additional processing and digitalization. This digital stethoscope is generally used in patient care. The three processing stages of this digital stethoscope are data collecting, preprocessing, and signal processing.
- Data Acquisition: Data acquisition uses a piezoelectric sensor and microphone to buffer, filter, and enhance the auscultated sound. After that, a digital signal is created from the auscultated sound.
- Preprocessing: The digital signal created in the previous stage is filtered in this stage, and any artifacts are eliminated to turn them into digital data.
- Signal Processing: The digital data produced in the previous stage is packed to a higher order classification and these data are clustered for medical diagnosis.
Doctors can flip the stethoscope over pediatric patients. It is recommended by many organizations to flip the stethoscope as it allows the doctor to use the bell of the stethoscope designed for pediatrics. The bell pediatrics Stethoscope has a small and sensitive bell for the best possible listening.
3M’s Littmann classic ll pediatrics Stethoscope is specially designed for children of age 4 to 5 years. Good acoustic sensitivity for both low and high frequencies is made possible by the dual-sided chest piece.
Part of pediatrics Stethoscope:
- Chest piece: A portion that moves over the chest to listen to a child’s internal sound is referred to as a chest piece. This chest piece should be smaller to fit the child’s body and it has a bell with a shape that is different from an adult stethoscope to amplify the sound of the heartbeat and breaths.
- Earpieces: The earpiece in the adult stethoscope will be at the side of the head whereas, in the pediatrics Stethoscope, it will be close together to hear the children’s heartbeat.
- Tubing: This is typically a tube that is connected to the flat diaphragm. This is used to carry sound through it.
- Ear tips: The ear tips in adult stethoscopes are usually round with a hole in them whereas pediatric Stethoscopes have more cones with no holes.
- Diaphragm: The bell-shaped or flat disc known as a “Diaphragm” vibrates when sound travels through it, creating a noise that is amplified by the tubing and audible to the human ear. Because of how small their chests must be, pediatric stethoscopes come in smaller sizes.
To flip a stethoscope:
A stethoscope consists of two sides, one side is the chest piece, and a bell is on the other side. To open a side doctor should rotate the chest piece. When a bell is open, the other one is closed and when it is closed, the sound is kept out of the bell.
Designed specifically for enhanced performance and durability. It provides high acoustic sensitivity, better lifetime usage, and longevity.
Features of Elko Stethoscope:
- Aluminium Dual Head Chest piece: The enhanced performance and durability of the Elko Stethoscope are achieved by this light weighted dual head chest piece. It has an adult tunable Diaphragm with a non-chill PVC ring.
- Frame: The frame is made of a 5mm stainless steel pipe positioned automatically at a correct angle to fit into the ear canal. The tension of the frame is adjusted according to the individual’s comfort.
- PVC tubing: This PVC tube is U-shaped and made of latex-free PVC material. This design is specifically made for high-quality sound transmission.
- Ear knobs: Synthetic material is used to make ear knobs, which gives ears a cushion comfort. They offer a superb acoustic seal once in the ear canal, blocking any outside disturbances.
Criteria to select the best stethoscope:
- Quality: stethoscope made of stainless steel is preferred as it ensures good acoustic performance and sound clarity and it is bacterial resistant. And the earpiece should have silicon material.
- Performance: Consistency is the primary factor in stethoscope choosing. In every test, the instrument should yield a consistent result.
- Durability: The stethoscope needs to long last over time and be reliable with continuous usage.
- Insurance: Typically, stethoscopes that are HSA and FSA-qualifying are favored above other insurance protection.
- Cost: Generally speaking, while considering criteria to buy any goods, the cost is a consideration. The outcome provided by the stethoscope is the most important factor to consider, so choosing a stethoscope that is consistent with the budget is prominent.
- Reputation: The product that is inspected by professionals are preferred.
