1. Preparation stage:
Make sure the appearance of the stethoscope is intact, and the earplugs and chest piece are clean.
According to the model of the stethoscope, confirm whether the required batteries or power cords are complete.
2. Installation and pairing:
If it is an electronic stethoscope with Bluetooth function, you need to install the corresponding software and pair it with the Bluetooth headset first.
3. Wearing the stethoscope:
Gently put the earplugs of the stethoscope into the ears, making sure there is no gap between the earplugs and the ears to ensure good sound transmission.
4. Prepare the subject:
The subject needs to loosen the collar and expose the chest to avoid noise caused by friction between the clothes and the stethoscope.
5. Select the listening position:
According to the organs to be listened to, select the heart, lungs and other positions for examination.
6. Adjust the volume:
According to the needs, adjust the volume of the stethoscope appropriately to ensure that the sound of the organ to be tested can be clearly heard.
7. Use the stethoscope:
Hand the stethoscope head and extend it to the required part for listening. According to different needs, select the required stethoscope head.
The multifunctional stethoscope can switch different listening heads as needed, such as large and small flat listening heads installed on the rotatable double-headed drum.
8. Check the status of the stethoscope:
Gently tap the diaphragm with your hand. If you can hear a sound, it means that the stethoscope is in standby mode.
If you can't hear the vibration sound, you can turn the listening head 180 degrees. You can hear a "click" sound to indicate that it is in place. Then tap the diaphragm with your hand. You should hear a vibration sound at this time, indicating that the stethoscope has been set up for standby.
9. Recording and analysis:
Record any abnormal heart sounds or respiratory sounds, and make preliminary analysis and judgment based on the sounds heard.
10. Cleaning and maintenance:
After use, gently wipe the listening head of the stethoscope with a clean cloth to keep it clean and hygienic.
11. Precautions:
Before use, you must ensure that the stethoscope is clean and disinfected to avoid cross infection.
When using, you should choose a quiet environment and minimize external interference.
