Description
Technical field
This utility model relates to the stethoscope field in medical apparatus and instruments, is specifically related to a kind of Multifunctional smart stethoscope showing, store and transmit electrocardiosignal.
Background technology
In the Clinics and Practices of current clinical medicine, stethoscope has just played important function from its invention.As in the physical examination of current clinical medicine depending on, touch, kowtow, in most important auscultation in auscultation, stethoscopic effect can not replace, and uses it, and doctor can auscultation H&L and borborygmus etc.But along with the development of intelligent medical treatment, the arriving of large data age, traditional stethoscope cannot meet clinical demand.
Traditional stethoscopic limitation main manifestations is in the following areas:
1. traditional stethoscope cannot obtain the content beyond auscultation, such as obtains Heart Rate and electrocardiosignal, can the delay time at stop for the timely diagnosis of doctor to critical patient.
2. conventional stethoscope is only used by clinician, and along with the development of tele-medicine, sufferers themselves, family members and basic unit doctor grow with each passing day to the requirement that auscultation content remote is held a consultation, and conventional stethoscope cannot meet this requirement.
3., for the rescue of clinical anxious danger disease patient, the acquisition of electrocardiosignal is most important.Stethoscope is that each doctor sees and treat patients the medical apparatus and instruments of patient's indispensability, and its popularity is the highest.Traditional stethoscope only can hear sounds, the rhythm of the heart of auscultation patient, but for ARR patient, this stethoscopic function is awkward and unable to do what one wishes, threatens that the arrhythmia of human life mainly comprises sick sinus syndrome, atrial fibrillation, room are flutterred, paroxysmal supraventricular tachycardia, ventricular flutter and ventricular fibrillation.Generally, traditional processing mode for doctor first auscultation pinpoint the problems, then row Electrocardioscopy is made a definite diagnosis, and then gives medical response.Even if electrocardiograph is in the obtainable at any time scope of doctor, at least need 10 minutes from auscultation to completing Electrocardioscopy, and these short 10 minutes, the state of an illness of patient may be delayed.
The typical electrocardiosignal of some patients may only exist in several minutes, and during row Electrocardioscopy, the arrhythmia of patient may turn multiple, cannot capture typical electrocardiosignal.
Traditional diagnostic mode if there is ventricular flutter, ventricular fibrillation, clarifies a diagnosis and need cardio-pulmonary resuscitation immediately, and only there is valuable 4-6 minute the prime time of cerebral resuscitation, so may delay valuable rescue time.
Based on above requirement, the applicant, on the basis of clinical practice for many years, in conjunction with the development of intelligent medical treatment and large data medical, sends out bright Multifunctional smart stethoscope.
The wisdom stethoscope that this utility model provides can combine complete to cardiac auscultation and electrocardiosignal, facilitates doctor to be beneficial to patient and rescues, and can by hear sounds and electrocardiosignal record, transmission and playback.
