Stethoscope (st é thoscope) is the most common diagnosis apparatus of inside and outside woman doctor, is the mark of doctor, modern times doctor
Learn and start from stethoscopic invention.Since on March 8th, 1817 is applied to clinic, shape and acoustic mode have not stethoscope
Disconnected improvement, but the change of its basic structure is little, mainly by pickup part (chest piece), conduction portion (sebific duct) and audition part
(ear piece) forms.Stethoscope type has alone stethoscope, double-purpose stethoscope, triple change stethoscope, vertical stethoscope, multi-purpose listens at present
Examine device and most emerging electronic auscultation device；Color also has the multiple color optional.Generally it is divided into by the various combination of can more
Type.Flat auscultation head is usually used in the difunctional flat can of auscultation high-pitched tone noise size and is used to detect low frequency heart sound, expands
Sound and the 3rd sound and first, second heart sound, can hear the heart sound of children.Bell auscultation head is usually used in auscultation bass bar height
Noise, can hear baby's heartbeat in abdomen.Tabular form auscultation head, is usually used in the pulse sound of auscultation wrist.For general, auscultation
Device is more big heavier, and pickup effect is better；Opposite, it is smaller lighter, carry more convenient, the design of giddy stethoscope
Exactly in order to solve this contradiction.The contact surface of auscultation head and body is bigger, and the audio of pickup is better.But human body surface has
Radian, if chest piece is excessive, can cannot not only cannot pick up well with human contact, sound equipment completely, and leakage can be also rushed down from gap
Go out, therefore, the size of auscultation head should be based on clinical need.At present, the diameter of piece for stethoscope,chest is nearly all unified in 45-50
