Working principle: when a doctor uses the stethoscope of the invention, firstly, the bag body 4 is extruded, air in the bag body 4 is discharged from the through hole 8, then the original expansion state is restored due to self elasticity, under the limit of the one-way valve, medical disinfectant contained in the bag body 2 is pumped into the bag body 4 through the pipe body 3, then the bag body 4 is extruded, the disinfectant in the bag body 4 is discharged from the through hole 8 and flows on a copper film on the lower surface of the stethoscope head 7, then the stethoscope head 7 is close to the skin of a patient, meanwhile, the bag body 4 is extruded, the disinfectant in the bag body 4 is discharged from the through hole 8, the stethoscope head 7 is attached to the body, and then the discharged disinfectant is smeared on an auscultation area on the body;

when a doctor squeezes the bag body 4, the fingers press on the bag body 4, and the pressing process is a process requiring continuous squeezing, and when the fingers continuously squeeze the bag body 4, the hands are difficult to grasp the stethoscope head 7, and under the obstruction of clothes on the body of a patient, the stethoscope head 7 is difficult to flexibly control; when the bag body 4 is extruded, the bag body 4 is obliquely extruded, the bag body 4 is extruded from the window 10 into the inner placing shell 9, under the constraint extrusion of the placing shell 9, the disinfection solution in the bag body 4 can continuously flow out, and meanwhile, the finger is liberated, so that a doctor can flexibly and stably control the stethoscope head 7, and the copper sheet on the stethoscope head 7 is effectively attached to the body of a patient;

after the stethoscope is used, disinfection preparation is needed, the bag body 4 is taken out from the placing shell 9, then the bag body 4 is required to be quickly restored to an initial expansion state, so that the bag body 4 is filled with disinfectant so as to be convenient for the next use of the stethoscope, for this purpose, the elastic sheet 11 is arranged in the bag body 4, and the elasticity of the elastic sheet 11 is used for supporting the bag body 4 after the bag body 4 is taken out from the placing shell 9, so that the bag body 4 is helped to be quickly expanded and pumped into the disinfectant, meanwhile, after the bag body 4 is extruded into the shell, the elastic sheet 11 and the bag body 4 are embedded into the placing shell 9 together, and the elastic sheet 11 is supported, so that the bag body 4 can be effectively extruded into the placing shell 9, and the extrusion and the discharge of the disinfectant in the bag body 4 are helped;

when the capsule body 4 is taken out of the placement shell 9, the surface of the capsule body 4 is smooth, the hands of doctors are smeared with disinfectant, the disinfectant can improve the lubrication between fingers and the surface of the capsule body 4, the fingers are difficult to scratch the capsule body 4 out of the placement shell 9 or rub the capsule body 4 out, therefore, the limiting angle 12 is arranged, firstly, the capsule body 4 can be extruded into the placement shell 9 to limit the position of the placement shell 9, the capsule body 4 is prevented from being excessively extruded into the placement shell 9, the fixedly connected point of the capsule body 4 and the placement shell 9 is extruded and broken, secondly, the limiting angle 12 is clamped at the edge of the window 10, and when the capsule body 4 is taken out of the placement shell 9, the capsule body 4 can be scratched out of the placement shell 9 by directly pushing the limiting angle 12, so that the control of the capsule body 4 by the fingers is convenient;

when the stethoscope is used by doctors, the earplug 15 is stuffed in ears, the metal bent pipe 16 is outwards expanded, the metal bent pipe 16 drives the chin rest 5 to outwards expand, and the extrusion plate 13 is simultaneously driven to extrude the bag body 2, firstly, the bag body 2 is extruded, so that disinfectant in the bag body 2 can quickly flow into the bag body 4 to be ready for next disinfection, secondly, when the extrusion plate 13 extrudes the bag body 2, the bag body 2 and the extrusion plate 13 generate opposite acting force, the extrusion plate 13 is pulled in the inner side direction of the chin rest 5, the angle of outwards expanding the chin rest 5 is restrained, the protection of the chin rest 5 is realized, and the chin rest 5 is prevented from being outwards expanded and damaged;

the external auditory meatus of each doctor is different in shape and size, the earplug 15 with a single size cannot be adapted, and the earplug 15 with adjustable size is arranged for the same; pulling the pull rod 19, the pull rod 19 pulls the first rod 22, the angle between the first rod 22 and the second rod 23 is gradually reduced, and meanwhile, the hinged position ends of the first rod 22 and the second rod 23 are outwards extruded to the cavity 21, so that the profile of the earplug 15 is gradually increased and is suitable for different external auditory meatus, and meanwhile, according to the external auditory meatus shape, the pull rod 19 at different positions is pulled, so that different positions on the surface of the earplug 15 are raised, the earplug 15 is more effectively attached in the external auditory meatus, and the sound propagation efficiency is improved; and the rubber ring 20 is arranged, so that the pulled rear pull rod 19 can be tightly pressed on the sleeve 17, and the stability of the shape and the size of the earplug 15 is ensured;

because the rotary connection point of the first rod 22 and the second rod 23 is in a conical shape, when the inner side wall of the cavity 21 is extruded and jacked, the smoothness of the outer contour of the earplug 15 is smaller, and the cooperation of the earplug 15 and the external auditory meatus is not benefited, therefore, the arc plate 24 is arranged, the cavity 21 is supported and jacked through the arc plate 24, the smoothness and the roundness of the outer contour of the earplug 15 are benefited, and the earplug 15 is more tightly attached in the external auditory meatus;

the plurality of elastic feelers 25 are arranged, so that after the pull rod 19 is pulled, the tip ends of the feelers 25 are embedded in the clamping points, so that the pull rod 19 is limited and fixed, the stability of the pull rod 19 is improved, and the stable top of the earplug 15 after the contour adjustment is ensured; the pull rod 19 is supported by elastic plastic materials and has elasticity, when the upper pull rod 19 is needed, the lower end of the pull rod 19 is outwards bent, and the pull rod 19 is arranged on the upper pull rod 19, so that flexible contour adjustment of the earplug 15 is realized; the pinch plate 26 is arranged at the other end of the pull rod 19, so that the pinch plate 26 is propped against the end face of the sleeve 17 far away from the earplug 15, and the other end of the pull rod 19 is prevented from shrinking into the rubber ring 20, so that the profile of the earplug 15 is difficult to adjust in the later stage; secondly, the buckle plate 26 is arranged, so that the pull-down control of the pull rod 19 is facilitated.

The front, rear, left, right, up and down are all based on fig. 1 in the drawings of the specification, the face of the device facing the observer is defined as front, the left side of the observer is defined as left, and so on, according to the viewing angle of the person.
