[0013] Compared with the prior art, the present invention provides a stethoscope with high stereo sensitivity, which has the following beneficial effects:

[0014] This stethoscope with high stereo sensitivity pulls the two first sleeves apart in opposite directions, and the pull rope during pulling stretches the counterweight ring upward. After the movement, the downward gravity of the two counterweight rings can keep the clamping force between the second sleeves consistent. In addition, the resistance-increasing mechanism can increase the resistance of the pull rope during movement, and prevent the second sleeves from returning to their original position after stretching, thereby ensuring that the two hearing mask mechanisms can always maintain appropriate and identical clamping force, which can provide certain protection for the doctor's ears and reduce the discomfort caused by wearing the stethoscope for a long time. The spring column can be used to fine-tune the clamping force between the second sleeves, and then, the counterweight ring will push the first sealing ring to move during the upward movement. After the first sealing ring moves, it will squeeze the gas in the sealing ring inward. After the gas is squeezed, it pushes the second sealing ring to drive the fixing rod and the push rod to move sideways, so that the hearing mask mechanism can be better fixed close to the doctor's ear, ensuring the effect of auscultation.

[0015] This stethoscope with high stereo sensitivity can place the card block in the second-stage card slot of the card slot after rotating the adjustment disk, and place the connecting hole in the connecting cavity after moving, so as to prevent external air from entering the sound amplification cavity through the connecting hole, and can effectively reduce the noise in the external air during auscultation. Then, when the doctor moves the stethoscope, the noise generated by the stethoscope itself during movement can be effectively weakened by the noise reduction mechanism, which significantly improves the accuracy of the auscultation sound. Then, the earmuff plate can be well fitted and fixed to the doctor's ear, and the auscultation sound can be transmitted through the sound guide hole. Among them, the stereoscopic degree and clarity of the auscultation sound can be improved by the sound amplification cavity, thereby ensuring the effect of auscultation, and the sound guide hole allows the auscultation sound to be better transmitted.

[0016] The invention relates to a stethoscope with high stereo sensitivity. When auscultating a patient, the pressure piece is squeezed inward to drive the pressure plate to move inward. After the pressure plate moves, the button is pressed to start the micro heater to work. Heat can be conducted through the heat conduction ring to quickly heat up the entire stethoscope head mechanism. During auscultation, discomfort caused by the excessively cold surface of the stethoscope head is avoided. Then, the third spring can drive the pressure plate and the pressure piece to return to their original positions, and the micro heater stops heating.

The third spring 910 is fixedly connected, and one end of the third spring 910 is fixedly connected to a pressure plate 911, and one end of the pressure plate 911 is fixedly installed with a pressure piece 905, wherein a sliding hole is provided in the middle of one end of the fixing ring 902, and the middle of one end of the fixing ring 902 is slidably connected to the pressure piece 905 through the sliding hole. The length of the pressure piece 905 is greater than the thickness of the stethoscope head 904. In use, when auscultating the patient, the pressure piece 905 is squeezed inward and drives the pressure plate 911 to move inward. After the pressure plate 911 moves, the button 909 is pressed to start the micro heater 908 to work. Heat can be conducted through the heat conductive ring 907, so that the entire stethoscope head mechanism 9 is quickly heated up, avoiding discomfort to the patient caused by the excessively cold surface of the stethoscope head 904 during auscultation. Then, the third spring 910 can drive the pressure plate 911 and the pressure piece 905 to return to their original position, and the micro heater 908 stops heating. The micro heater 908 is a prior art and will not be described here.
