The earplugs are used to plug into the doctor's ears and are connected to the Y-tubes through the earrings so that the sound can be transmitted. The stethoscope head is usually made of metal or plastic and is placed on the patient's body to collect the sound, while the pleura is a thin film that fits tightly on the stethoscope head and can enhance the transmission of sound. Modern stethoscopes have a variety of different designs, which can be single-headed or double-headed, providing sound detection at different frequencies. Some high-end stethoscopes may also be equipped with electronic amplification devices to improve the sensitivity and accuracy of sound detection. The stethoscope is an indispensable tool for doctors to check patients on a daily basis. It can not only help diagnose heart disease, respiratory diseases, and certain digestive system diseases, but can also be used to listen to the sound of blood flow in blood vessels during blood pressure measurement. Because of its intuitiveness, ease of use, and portability, the stethoscope has become one of the most trusted partners of doctors.
[0003] In order to ensure the accuracy of the auscultation results of the stethoscope, in the prior art, many people will combine earmuffs with the stethoscope, so as to ensure that the medical staff can minimize the interference of the external environment on the auscultation content during the auscultation process. However, the combination method in the prior art is relatively rough. After the earmuffs and the stethoscope are combined, they cannot adapt to the head shape of the medical staff, and then after long-term and multiple uses, it will cause discomfort to the medical staff's head.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0021] A physical noise reduction stethoscope, such as Figure 1 As shown, it includes a noise reduction earmuff, an earring 4, an earplug 7 fixedly connected to the earring 4, a Y-shaped tube connected to the earring 4, a hose 5 connected to the Y-shaped tube, and a pleural head 6 connected to the hose 5.
[0022] like Figure 2 and 3 As shown, the noise reduction earmuffs include a headband 1, a strap piece 2 fixedly connected at both ends thereof, a cover 3 movably connected to the strap piece 2, a sound insulation layer 301 fixedly connected to the cover 3, and an ear pad 302 fixedly connected to the outer circle of the sound insulation layer 301, a sponge cushion 101 is fixedly connected to the inner circle of the headband 1, the sound insulation layer 301 is made of sound-absorbing sponge material, the ear pad 302 is made of memory sponge material, a guide groove 3011 is provided on the cover 3 and the sound insulation layer 301, a channel groove 2011 connected to the guide groove 3011 is provided on the strap piece 2 and the cover 3, and the earring 4 with the earplug 7 passes through the channel groove 2011 and the guide groove 3011.
[0023] A connecting tube 201 is fixedly connected to the belt piece 2, and a hollow ball 202 connected to the connecting tube 201 is fixedly connected to one end of the connecting tube 201 away from the belt piece 2. A through hole 2021 is provided on the hollow ball 202. The belt piece 2 is provided with a hole connected to the connecting tube 201. The hole, the connecting tube 201, the hollow ball 202 and the through hole 2021 form a channel groove 2011. A ball groove for accommodating the hollow ball 202 is provided on the side of the cover shell 3 facing the belt piece 2. The ball groove is connected to the guide groove 3011, and the volume of the ball groove is smaller than the volume of the hollow ball 202.
[0024] When the medical staff wears the utility model and performs auscultation, they only need to hold the cover shells 3 on both sides and pull outwards to make the headband 1 and the belt piece 2 elastically deformed. At the same time, the cover shell 3 can also drive the earrings 4 to expand outwards together, so that the Y-shaped tube can be elastically deformed, so that a space for the medical staff to put their heads into can be formed between the noise reduction earmuffs and the earrings 4 on both sides. Then, when wearing the medical staff, they can hold the cover shell 3 to deflect relative to the belt piece 2. When the cover shell 3 moves, the cover shell 3 can move at a larger angle relative to the belt piece 2 through the cooperation of the ball groove and the hollow ball 202, so that the cover shell 3 on both sides can cater to the head shape of the medical staff. In this process, the earrings 4 always pass through the channel groove 2011, deflect in the guide groove 3011 with a fan-shaped cross section, and adjust the position. The groove width of 3011 is larger than the tube diameter of the earring 4, so that the cover 3 will not hinder the deflection of the earring 4. At this time, even if the angle of the cover 3 is deflected relative to the belt piece 2, the earring 4 and the earplug 7 can still find a suitable position and be inserted into the ear of the medical staff, and the soft pad 101 on the headband 1 can be padded between the headband 1 and the top of the medical staff's head, so as to avoid the headband 1 with a certain hardness from causing headaches to the medical staff after long-term contact with the head of the medical staff. After the coordination is good, the ear pad 302 and the sound insulation layer 301 are set, so that when the noise reduction earmuff is put on the head of the medical staff, the cover 3 can block the sound waves generated by the external sound through the sound insulation layer 301 and the ear pad 302, ensuring that the medical staff is not easily disturbed when using the stethoscope. At the same time, after using the stethoscope for a long time and many times, the medical staff will still not feel uncomfortable.
[0025] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
