1, the use of stethoscope
1. 1. Put the binaural receiver in the ear and hold the listening head to the required position for diagnosis and listening;
1.2, choose your own listening head according to different needs; The multifunctional stethoscope is equipped with large and small flat listening blocks, which are mounted on a rotatable double-headed drum, and it includes a very accurate anti-stick valve.
1.3, put the binaural receiver in the ear.
1.4, tap the diaphragm gently, and you can hear the sound, so you can confirm that the stethoscope is in standby state.
1.5. If you can't hear the vibration of the diaphragm, turn the listening head to 180, and when you hear a click, it means that you are in place and facing the opposite side.
1.6. Then, pat the diaphragm with your hand. At this time, you should hear the vibration, which means that the stethoscope has been set up to work.
1.7. At this time, you can use this stethoscope to diagnose the patient.
How to wear stethoscope correctly when the ear canal leans forward;
The stethoscope is designed according to the patented ergonomic ear canal and sinus. It can comfortably fit the listener's ear canal without making you feel tired and uncomfortable. Before wearing the stethoscope, please pull the ear tube of the stethoscope outward; Tilt the metal ear canal forward, insert it into your external auditory canal, and let the ear sinus and your ear canal close tightly; Everyone's ear canal is different in size, so you can choose an appropriate ear sinus. If you wear it correctly, but the tightness between the ear sinus and the ear canal is not good and the auscultation effect is not good, please pull out the ear canal to adjust its elasticity. Improper wearing method will lead to poor auscultation effect if the sinuses and ear canal are not tightly closed. For example, if the ear tube is worn backwards, it will be completely inaudible.
Remove sundries: If the stethoscope is put in your pocket or not regularly maintained, cotton wool, fibers or clothes dust may block the ear canal of the stethoscope. Regular maintenance and cleaning can avoid the above situation.
Check the tightness: the high-quality sound transmission effect of stethoscope is related to the tightness between stethoscope and patient's body surface, stethoscope and listener's ear canal. Loose parts of the listening head, loose Y tube and damaged Y tube will all affect the sealing performance. The better the sealing, the more accurately the sound in the patient can reach the listener's ear. So always check the state of the stethoscope.
Double-sided stethoscope:
When using a double-headed stethoscope, the user needs to switch the clock face or membrane face mode of the head to use. When using the membrane face, the clock face will be closed to avoid interference. or vice versa, Dallas to the auditorium
2. Matters needing attention when using stethoscope
2. 1, wearing method of stethoscope, the working principle of stethoscope is mainly to connect the acquisition part of the instrument with the patient, and put the ear tube part in the doctor's ear. Although the design of the ear tube conforms to the basic principles of human mechanics and fits the doctor's ear structure well, it needs to be fine-tuned when used because everyone's ear structure is different. It should be noted that after wearing the stethoscope, you can gently pull down the ear canal so that the position of the ear canal is just in the external auditory canal. For convenience, the whole metal tube should be tilted forward to reduce external interference and ensure the best effect.
2.2, stethoscope before use, stethoscope as an important clinical medical machinery and equipment, before use, the stethoscope needs to have a strict inspection process, the first is to remove the sundries on the machine, because the stethoscope may be stained with hair clippings and other sundries in the ear canal because it is not used for a long time, which will directly affect the transmission of sound in the ear canal, so it is necessary to do a good job of regular cleaning and maintenance. Another point is to check the tightness of stethoscope, because the sound information collected from patients needs to be well sealed as a guarantee, so as to better help doctors make judgments. The inspection is mainly to check the Y interface of stethoscope and listening head, and repair and adjust it in time if it is loose.
2.3, excluding external sound interference, stethoscope and peacetime headphones have certain similarities, so it will also face the earphone effect. The so-called earphone effect refers to the noise generated when its unit parts rub against the body and other external objects, which makes the listener's hearing dry. In the stethoscope, there will be a lot of noise caused by friction with the doctor's clothes. At this time, you can try to clamp the ear canal with clothes, which can help doctors reduce the noise caused by friction and get the best hearing effect.
