What is the difference between a stethoscope and a stethoscope?
Two types of equipment - a stethoscope and a stethoscope is very popular in medicine. They are designed to listen to noise in the internal organs and have many similar characteristics. But at the same time there is a difference. For the analysis of devices and the correct choice we will carry out the description and we will define what is a stethoscope and a phonendoscope.
Description of the stethoscope
Stethoscope called a special medical device that is used to fix the noise of internal organs. With the help of a stethoscope, various abnormalities and pathologies in the human body are determined.
Stethoscope design consists of several elements that are responsible for specific functions:
- The head, which is in contact with the body, to listen to sounds - auscultation. There are one-way (with a membrane or funnel) and two-way version (combines two elements). Membrane for noise of high purity, and the funnel catches low frequency;
- Wire is responsible for conducting sound from the head to the ears of Dr.;
- Bows. Help to conveniently lock the device and are connected to the sound line and olives;
- Olives. Nozzles that are hermetically fixed in the ears.
Today, several varieties of medical devices are used, depending on what the stethoscope listens to and the direction of its use:
- For Pediatrics. Use stethoscopes with excellent quality acoustics, through which it is possible to listen to the heart rate of the child. Modern pediatric devices do not give a feeling of cold and are the most comfortable for the little ones;
- In cardiology. The device is designed to listen to high and low frequencies of the heart;
- In obstetrics (Pinara stethoscope). Help to determine the heart rate of the baby in the womb;
- For therapy. Advanced options with a microphone and headphones, make it possible to listen to the heartbeat even in noisy places.
Overview and purpose of the phonendoscope
Medical device-a phonendoscope, in design it is very similar to a stethoscope, but with its feature - an additional membrane. With its help, the sounds are amplified, which allows for a more detailed diagnosis. The individual models have two tubes that improve listening. The material of the ring is plastic or metal.
Depending on the application, the phonendoscopes are divided into:
- Devices for cardiology. The frequency range from the lowest to the highest, it is easy to change the side, from the membrane to the funnel;
- Shelves with flat head. Applied for more thorough listening of internal organs-the respiratory tract, gastrointestinal tract, etc.
A high level of listening is the main difference between a stethoscope and a stethoscope. It is used most often for diseases of the respiratory system and to determine wheezing. The device measures the number and rhythm of heart contractions, digestive disorders and arteries.
What is the main difference between the devices?
Differences between medical devices and stethoscope phonendoscope is not always noticeable to people that do not have a direct relationship to them. Their appearance is almost identical. But qualified professionals can easily see the difference and choose a more suitable option depending on the problem. Therefore, there is no answer to the question what is better than a stethoscope or a stethoscope, it all depends on the application and diseases of patients.
The main difference is that the membrane of the phonendoscope can conduct pulses of a higher frequency. Stethoscope also specializes in low-frequency listening, which can drown out the high level.
A special membrane of the phonendoscope does not reduce the sounds of different frequencies and determines them well, so it is the best option for diagnosing the heartbeat and digestive organs.
It is the functionality of the devices that is the main difference between a stethoscope and a phonendoscope.
