Description
Technical field
This utility model relates to a kind of stethoscopic improvement, specifically a kind of volume amplifying stethoscope.
Background technology
At present, the stethoscope that uses clinically is made of stainless steel tube, rubber tube, flexible connection piece, stethoscope head, this traditional diagnostor, though existing extensive use also has weak point: the one, stethoscopic volume can not be regulated, the auscultation weak effect; The 2nd, in the auscultation process, cry if run into the patient, accompany and see the sound such as speaking of patient, all can affect quality of diagnosis.
Summary of the invention
It is a kind of simple in structure, easy for operation that the purpose of this utility model is to provide, and can avoid the interference of external volume, improves the volume amplifying stethoscope of auscultation volume and quality of diagnosis.
For reaching above purpose, technical solution adopted in the utility model is: this volume amplifying stethoscope, by stainless steel tube, rubber tube, flexible connection piece consists of, it is characterized in that establishing earphone in the upper end of stainless steel tube, the lower end is connected with the rubber tube upper end, the lower end of rubber tube and the metallic framework of detection head join, the electronics public addressor amplifier is located on the rubber tube and establishes switch, wire is located in the rubber tube and is connected with the electronics public addressor amplifier, and two ends join with earphone and microphone respectively, and microphone is located in the detection head, electronics public addressor amplifier layout, adopting TDA2822 sonifer amplifying circuit figure, is known technology, therefore do not set forth.This utility model is also implemented by following measure: described detection head, consisted of by metallic framework, vibrating diaphragm, through hole, rubber sleeve, and vibrating diaphragm is established in the lower end of metallic framework, and through hole is located in the vibrating diaphragm, and rubber sleeve is located at the outside of metallic framework.When using this utility model, the medical worker hands detection head with earphone plug and two in ear, is placed on patient's position, ambition, then opens the switch on the electronics public addressor amplifier, can go to a doctor.
The beneficial effects of the utility model are: compare with present stethoscope, have easy for operationly, can avoid the interference of external volume, improve the advantage of stethoscope volume and quality of diagnosis.
