Abstract
A visual wave-shaped electronic stethoscope mainly comprises a cardiopulmonary sound sensor, a sound acquisition device, a sound amplification device, a digital signal processor (DSP), an earphone and a display unit. The cardiopulmonary sound sensor obtains human cardiopulmonary sound signals and sends the signals to the sound acquisition device which performs analog to digital (A/D) conversion on signals, and the output is connected with the DSP; the DSP performs filtering, environment de-noising, storing and emission on the received signals and sends the signals to the display unit and the sound amplification device; and the output of the sound amplification device is connected with the earphone. The visual wave-shaped electronic stethoscope has the advantages that an environment de-noising function is provided, oscillograms can be switched according to needs of doctors, doctors can observe cardiac sound and lung sound oscillograms directly during an auscultation process, the structure is attractive and simple, and the stethoscope is convenient to carry.
Description
Technical field
This utility model relates to medical apparatus and instruments, particularly a kind of electronic stethoscope of checking hear sounds and respiratory murmur waveform.
Background technology
Stethoscope is the most frequently used diagnosis apparatus of inside and outside woman doctor, is doctor's sign, and modern medicine namely starts from stethoscopic invention.Stethoscope since be applied to clinical since, profile and acoustic mode have continuous improvement, but its basic structure changes little, the stethoscope that occurs in the market mainly partly is comprised of pickup part, conduction portion and audition, function singleness, can only carry out simple auscultation usefulness, the doctor can not show this patient's hear sounds and the waveform of respiratory murmur in real time when giving patient's auscultation.
Summary of the invention
In order to solve the problem of above-mentioned proposition, this utility model provides a kind of VWF electronic stethoscope, and the doctor can carry out auscultation limit, limit and check this oscillogram, can understand fast patient's the state of an illness.
The technical scheme that this utility model adopts is that it mainly comprises heart and lung sounds sensor, voice collection device, sound amplifying device, digital signal processor, earphone and display unit a kind of VWF electronic stethoscope; The heart and lung sounds sensor is sent to voice collection device after obtaining human body heart and lung sounds signal, and voice collection device is changed signal A/D, and output linking number word signal processor; Digital signal processor carries out filtering to the received signal, ambient noise-reduction is processed, stored and emission, sends display unit and sound amplifying device to; Sound amplifying device output frames connecting with headphone, battery adopts general rechargeable battery.
Described signal radiation pattern can pass through bluetooth or usb data line, and the mode of described signal storage can be portable storage tank.Described display unit can be LCDs, PC, panel computer; Described hear sounds and lungs sound can switch by filter function.
The beneficial effects of the utility model are, and have the ambient noise-reduction function, can be according to doctor's demand switching waveform figure, and the doctor can observe directly hear sounds and lungs sound oscillogram in the process of carrying out auscultation, and structure is attractive in appearance simple, easy to carry.
Description of drawings
Accompanying drawing is structural representation of the present utility model.
Wherein, 1, heart and lung sounds sensor; 2, voice collection device; 3, digital signal processor; 3-1, storage; 3-2, emission; 3-3, ambient noise-reduction; 3-4, filtering; 4, display unit; 5, sound amplifying device; 6, earphone.
The specific embodiment

As shown in the figure, a kind of VWF electronic stethoscope it mainly comprise heart and lung sounds sensor 1, voice collection device 2, sound amplifying device 5, digital signal processor 3, earphone 6 and display unit 4; Heart and lung sounds sensor 1 is sent to voice collection device 2 after obtaining human body heart and lung sounds signal, and voice collection device 2 is with the signal A/D conversion, and output linking number word signal processor 3; Digital signal processor 3 carries out to the received signal filtering 3-4 and ambient noise-reduction 3-3 processes, and sends display unit 4 and sound amplifying device 5 to; Sound amplifying device 5 output frames connecting with headphones 6, battery adopts general rechargeable battery.
Described digital signal processor 3 can advance the signal that receives the storage 3-1 of place and emission 3-2.
Described storage 3-1 mode can be removable memory, and emission 3-2 mode can be bluetooth or usb data line.
Described sound amplifying device 5 can be enlarged into sound 10 times ~ ~ 18 times.
The doctor can observe directly hear sounds and lungs sound oscillogram in the process of carrying out auscultation, and has the ambient noise-reduction function, regulates voluntarily the size of volume, can be according to doctor's demand switching waveform figure, and structure is attractive in appearance simple, easy to carry.
The above, only being this utility model preferred embodiment, is not that this utility model is done any pro forma restriction, any simple modification that all foundations technical spirit of the present utility model is done above embodiment, equivalent variations and modification still belong in the scope of technical solutions of the utility model.
