For addressing the above problem, this utility model by the following technical solutions:

A kind of stethoscope, two earplugs, transaudient bar, Y type sebific duct and auscultation heads about comprising, it is characterized in that: vertically be provided with a barrier film in the described Y type sebific duct, described barrier film is divided into two separate airtight passages with the inner chamber of Y type sebific duct, one end of described two airtight passages respectively with about two earplugs be connected, the other end is connected with the auscultation head.

Below be further improvement to technical scheme:

In the described auscultation head microtelephone is installed, described microtelephone is connected by the lead recorder outer with being arranged on the auscultation head.

Beneficial effect

This utility model is divided into two separate airtight passages by barrier film with the inner chamber of Y type sebific duct, it is communicated with two earplugs of effect respectively, acoustic definition and sensitivity have been improved, the auscultation head is connected with recorder, make the sound energy record in patient abdominal cavity, especially in outdoor or environment that other noise is bigger, because extraneous interference, can't carry out immediately the sound of hearing by stethoscope the doctor under the situation of pathology judgement, reset by recorder, make the doctor judge patient's the state of an illness more accurately, avoided mistaken diagnosis occurring or mistake is examined, make patient can access promptly and accurately treatment.
