The technical solution includes a sound insulation component 1, a compression and telescopic member 2 vertically arranged in the middle of the upper end of the sound insulation component 1, and a collection component 3 threadedly connected to the lower end of the compression and telescopic member 2. A handle member 4 is horizontally arranged on the right side of the sound insulation component 1, and the other end of the collection component 3 is electrically connected to an analyzer 5. The collection component 3 is located at the lower end of the cavity of the sound insulation component 1. The collection component 3 includes an auscultation shell 31, a pickup seat 32 arranged at the upper end of the cavity of the auscultation shell 31, and a pickup 33 is arranged at the lower end of the pickup seat 32. The sound insulation component 1 includes a pressing plate 11 and a sound insulation cover 12 arranged on the bottom surface of the pressing plate 11. A first wire arrangement seat opening 13 is opened in the middle of the pressing plate 11, and a second wire arrangement seat opening 14 is opened in the middle of the top surface of the sound insulation cover 12. The lower end of the cavity of the sound insulation cover 12 An arc chamfer 121 is provided on the end periphery, the sound insulation cover 12 is horn-shaped, and the sound insulation cover 12 is made of silicone. The compression and telescopic member 2 includes a sliding seat 21, a sliding rod 22 movably mounted on the sliding seat 21, a spring 23 mounted on the lower end of the sliding rod 22, and an external threaded column 24 arranged at the bottom end of the sliding rod 22.

[0021] Working principle:
[0022] When in use, hold the handle 4, move it to the heart and lung area of the patient's body, and press down the handle 4 with a little force, the sound insulation cover 12 will stick to the patient's body. Because the sound insulation cover 12 is made of silicone and is horn-shaped, the lower end of the sound insulation cover will expand and deform, so that the collection component 3 is in a sealed cavity, isolating from external noise interference. At the same time, under the downward pressure of the user, the collection component 3 slides up on the slide seat 21 through the slide bar 22. At this time, the spring 23 will be in a taut state, providing downward pressure on the collection component 3, so that the bottom surface of the collection component 3 is close to the patient's body, allowing the microphone 33 to pass through each stethoscope hole 313 and collect the patient's heart and lung sounds in the sealed cavity of the sound insulation cover 12, and finally the signal of the microphone 33 is transmitted to the analyzer 5 for analysis.
