Description

Medical stethoscope

Technical field

This utility model relates to a kind of medical apparatus and instruments, is specifically related to a kind of Medical stethoscope.

Background technology

Stethoscope, is the most frequently used diagnosis apparatus of inside and outside woman doctor, is doctor's mark, and modern medicine starts from stethoscopic invention.Stethoscope since be applied to clinical since, profile and acoustic mode have continuous improvement, but that its basic structure changes is little.First stethoscopic invention is apart from the modern history that has more than 100 year in the world.The some day in 19th century, the carriage coming at a full speed stops in front of the door at luxurious mansion of Paris, FRA, has gone down famous doctor's raney gram on car, and he is please diagnosed a disease to Miss noble here.With a haggard face Miss, is sitting on settee, is knitting tightly two eyebrows, and hands is sealed chest, seems seriously ill.Sealing chest Deng Miss and telling after the state of an illness, she has caught heart disease raney gram doctors suspect.If make diagnosis correct, preferably hear the rhythm of the heart, in " the Hippcrates collected works " of ancient Greek, just record doctor and pressed close to ear the diagnostic method of patient's thorax examination cardiopulmonary sound.Thunder Neck is also therefrom known this auscultation method, is usually used for examining at ordinary times patient.But doctor is at that time that the suitable position that is directly attached to patient body across a towel ear diagnoses the illness, and this patient is young Miss noble, and this method is obviously improper.Raney gram doctor paces on one side in parlor, and keeping in mind on one side can be by new method.See the appearance that doctor thinks long and hard, people within doors also dare not at will walk about and speak.Stethoscopic inventor's raney gram doctor, while walking, appears suddenly something that a few days ago he runs in one's mind in raney gram doctor's brain---and by a street in Paris, stacking a pile and repairing the timber that house is used.Several children play on rollway, the one end that wherein has individual child to knock a timber with a spike, the child that he is other be attached to timber with ear another bring in listening, he strikes, ask " having heard what sound? " " having heard interesting sound? " children are laughing at and are answering.Just, in the time that they play cheerfully, raney a gram doctor pass by here, and he has been attracted by playing of children, just stops, and he is carefully seeing that children play.He stands over there and has seen for a long time, has suddenly walked in the past and has asked gamely: " children allow me also hear this sound all right? " children have promised giocoso.He is pasting ear one end of timber, listens in earnest children to knock the sound of timber with iron nail." hear? sir." " heard, heard! " a raney gram doctor has a brainwave, and makes people call in a ground paper at once, and paper is rolled into a cylinder tightly, presses at the position of Miss's heart for one, other end is attached on the ear of oneself.Really, the sound of Miss's heartbeat wherein slight noise all listened clearly by a raney gram doctor.He is extremely happy, and tells Miss's the state of an illness to make a definite diagnosis, and can hold prescription successfully a little while.After a raney gram doctor goes home, look for a hollow wooden pipe of the special making of people at once, long 30cm, bore 0.5cm, for the ease of carrying, therefrom subdivision is two sections, has screw thread to be rotatably connected, Here it is first stethoscope, it is used for listening the monaural formula couoxylon of fetal heart sound very similar to obstetrics now.Because this stethoscope appearance is as flute, so be called as " doctor's flute ".Thunder Neck has been invented wooden auscultation apparatus thus, is a kind of straight tube of hollow.Thunder Neck is by it called after stethoscope.Afterwards, raney gram doctor had done again many experiments, finally determined, connects rubber tube make uniaural stethoscope, better effects if with flaring Dens Elephatis pipe.The age that uniaural stethoscope is born is 1814.Due to stethoscopic invention, make raney gram can diagnose out many different chest diseases, he is also " father of thoracic cavity medical science " by descendant's honor.A raney gram doctor dies from 1826, is only 45 years old.1840, Britain's doctor George Fei Lipu toll bar was improved the uniaural stethoscope of raney gram design.Toll bar thinks, ears can more correctly be diagnosed.He invention stethoscope be by two flexible rubber tubes of two earplugs be connected to can with the receiver of Body contact on, stethoscope is a cone that hollow is specular.The stethoscope of toll bar, contributes to the sound of physicians during auscultation vein, tremulous pulse, the heart, lung, enteral portion, even can hear the hear sounds of fetus in parent.Nineteen thirty-seven, Kai Er improves the stethoscope of toll bar again, increased by second can with the receiver of Body contact, can produce stereophonic effect, be called compound stethoscope, it can find out patient's focus place more accurately.Unfortunately the improved goods of Kai Er is not widely adopted.Recently there is again electronic stethoscope to come out, its energy voice emplifying, and can make one group of doctor hear by the sound in diagnosis person's body simultaneously, and can also record cardiac murmur, more approaching with normal hear sounds.Although stethoscope constantly comes out, what doctors generally preferred to use remains by raney gram design, through the old type stethoscope of toll bar improvement.The existing stethoscopic openings of sizes that generally all can not regulate, adaptation that can only be passive, if little very pain, large and can compare pine, and the ice of receiver comparison, when use, may have ice-cold sense, especially child can relatively react large, and child's comparison is active, not to be easy to operate etc.
