Stethoscope industry definition refers to the most commonly used diagnostic tools for internal and external women and children physicians. It is the symbol of physicians. Modern medicine begins with the invention of stethoscopes. Since the stethoscope was applied to the clinic on March 8, 1817, the shape and sound transmission have been continuously improved, but its basic structure has not changed much. It mainly consists of the pickup part (chest piece), the conductive part (hose) and the listening part. (earpieces) composition. More content, the following is a small series of stethoscope industry definition and classification.
Variety of stethoscopes:
Stethoscope types currently include single-use stethoscopes, dual-use stethoscopes, three-purpose stethoscopes, vertical stethoscopes, multi-purpose stethoscopes, and the latest electronic stethoscopes; colors are available in a variety of colors. It is generally divided into multiple types by different combinations of the heads. The flat auscultation head is often used for auscultation of high-pitched murmurs. The dual-function flat-shaped head is used to detect low-frequency heart sounds, expansion sounds and third sounds, and first and second heart sounds. The heart sounds of children can be heard. The bell-shaped auscultation head is often used to auscultate the bass treble and can hear the baby's heartbeat in the abdomen. The auscultation head is often used to auscultate the pulse sound of the wrist.
Type of stethoscope:
Acoustic stethoscope
Acoustic stethoscope is the earliest stethoscope and a diagnostic tool for most people. This stethoscope is a symbol of the doctor, who wears it around his neck every day. Acoustic stethoscopes are the most commonly used.
Electronic stethoscope
The electronic stethoscope uses electronic technology to amplify the body's sound, overcoming the high noise of the acoustic stethoscope. The electronic stethoscope needs to convert the electrical signal of the sound of the sound and then be amplified and processed for optimal listening. They are based on the same physical principles as acoustic stethoscopes.
The electronic stethoscope can also be recorded with a computer-assisted auscultation plan to record the heart's sound pathology or innocent heart murmur.
Taking a stethoscope
Some electronic stethoscopes have direct audio output that can be used to connect to external recording devices, such as laptops or MP3 recorders. Save these sounds, listen to previously recorded sounds through a stethoscope headset, and the doctor can do more in-depth research, even remote diagnosis.
Fetal stethoscope
In fact, the fetal stethoscope or fetal mirror is also a kind of acoustic stethoscope, but it is detached from the ordinary acoustic stethoscope. The fetal stethoscope can hear the sound of the fetus in the belly of the pregnant woman. It is very beneficial for the care during pregnancy.
Doppler stethoscope
A Doppler stethoscope is an electronic device that measures the Doppler effect of reflected waves from ultrasound waves in body organs. The motion is detected as a change in frequency due to the Doppler effect, reflected waves. Therefore, Doppler stethoscopes are particularly well suited for handling moving objects such as beating hearts.
