It has gradually become the representative of doctors. In clinical practice, the stethoscope can help doctors to timely judge the condition of the patient's heart, lungs, chest cavity and other parts, and assist in the judgment of the condition. The wearing and operation of the stethoscope have very strict influences, otherwise it may be affected by external sounds. After being disturbed by the outside world, it will cause errors in the doctor's judgment, which will directly affect the patient's condition. Therefore, the use of the stethoscope needs to be standardized and valued. It mainly includes the following points: 1. The wearing method of the stethoscope. The working principle of the stethoscope is mainly to connect the collection part of the instrument with the patient, and the ear tube part is placed 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 very well, because everyone's ear structure is different, it needs to be fine-tuned when using it. One thing to note is that after wearing the stethoscope, you can gently pull the ear tube down so that the position of the ear tube is just in the external auditory canal. The entire metal tube should be tilted forward for ease of use to reduce external interference and ensure the best effect. 2. Inspection before using the stethoscope. As an important mechanical device in clinical practice, the stethoscope needs to have a strict inspection process before use. The first thing is to remove the debris on the machine, because the stethoscope may be stained with hair, paper scraps and other debris in the ear tube due to long-term non-use, which will directly affect the propagation of sound in the ear tube, so it is necessary to do regular cleaning and maintenance. Another point is to check the sealing of the stethoscope, because the sound information collected from the patient needs to have good sealing as a guarantee, so as to help the doctor make judgments. During the inspection, the Y interface and the head of the stethoscope are mainly checked. If there is any looseness, it should be repaired and adjusted in time. 3. Eliminate external sound interference. The stethoscope has certain similarities with the headphones used in daily life, so it will also face the headphone effect. The so-called headphone effect refers to the noise generated when its unit parts rub against the body and other objects in the outside world, which dries the listener's hearing. The stethoscope will also produce a lot of noise due to friction with the doctor's clothes. At this time, you can try to clamp the ear tube line with the clothes, which can help the doctor reduce the noise caused by friction and get the best hearing effect. The stethoscope is a very important auxiliary diagnostic tool for doctors in clinical practice. When using it, the operation should try to control the error as much as possible to ensure accurate judgment, reduce problems with the machine itself, do a good job of inspection and maintenance, reduce external interference, and ensure the accuracy of the results.
