Abstract

The utility model relates to an wireless electronic stethoscope for medical practitioner, which comprises a sound collecting and transmitting part and a sound receiving and processing part. The sound collecting and transmitting part consists of a sound sensor, a front amplifier, a high pass filter, an audio frequency sampler, a MCU and a radio transmitting module. When the sound sensor collects a sound, the sound is not only processed by the front amplifier, but also is processed by the high pass filter; the sound receiving and processing part consists of a radio transmitting module, a MCU, a monitor, a sound output part and a computer connection part.. The monitor translates the received sound into oscillogram and conclusion and displays them. The utility model adopts wireless transmitting method realizing long distance transmission and is connected with the computer, paving the way for the information collected to be post processed, and the sound signals collected can be amplified processed to be translated into diagram signals, providing diagnosis intelligently, making the diagnosis direct-viewing and convenient; the utility model can also realize sound signals multi-receiving by a plurality of people, beneficial for consultation and teaching.

Description

The wireless electron stethoscope

Technical field

This utility model relates to a kind of detecting instrument of medical domain, the stethoscope that specifically a kind of medical worker uses.

Background technology

Relevant by retrieval patent documentation does not retrieve the radio stethoscope identical with this utility model structure at present as yet.The stethoscope that domestic tradition is used generally is made of its principle can, earplug, metal pipe frame and sebific duct: with diaphragm-operated vibration, the vibration by air is delivered to sound on the earplug.Because its structural reason can only be used for a people, and be subjected to the restriction of voice conducting pipe length, can only do close contact, then should dress corresponding isolation clothes for patient medical worker and check with infection symptom, brought very big inconvenience to detecting diagnosis.Add to sound and do not carry out processing and amplifying, then brought certain degree of difficulty to audible inspection.And because its clamping force, life-time service brings for medical worker ear and feels under the weather.Though existing electronic stethoscope has had very big progress on traditional stethoscope, but sound obtained through processing and amplifying by the auscultation head, and reach detection diagnosis to human body.ZL200420088361.8, name is called " wireless electron stethoscope ", discloses a kind ofly just can realize wireless auscultation and record, the wireless electron stethoscope that cost is very cheap by common radio cassette player, but also owing to its structural reason, so can only reach the effect of audition diagnosis.

Summary of the invention

The purpose of this utility model is will provide a kind of acoustical signal is changed into figure, carries out intelligent diagnostics, remote transmission signal, and the wireless electron stethoscope that can be connected with computer.

Technical characterictic of the present utility model is: considering that auscultation is effective, be designed to comprise sound collection and send the wireless electron stethoscope of part harmony sound reception with the processing section on the basis intuitively, sound collection is made up of sound transducer, preamplifier, high pass filter, audio sample device, Single-chip Controlling part, wireless transmitter module with the transmission part, the sound that described sound transducer collects, after preamplifier is handled, also passed through the processing of high pass filter; Sound receives with the processing section and comprises that wireless receiving module, Single-chip Controlling part, display, audio frequency broadcast part, computer interface part, and the sound that receives is converted into waveform to described display and diagnosis shows.Described high pass filter is that 50HZ is every the ripple device.Wherein a kind of among described wireless transmitter module can be a bluetooth, 802.11b/g, 2.4GHz the are wireless monolithic transceiving chip nRF2401.Described sound reception is analyzed the sound of gained with the display in the processing section, provides preliminary conclusion, and shows on display screen.Described sound reception is transposed to computer with the processing section with the sound of collecting and carries out post-processed.

During use, sound collection contacts with human body with the transmission part, sound transducer with the sound that collects after preamplifier, high pass filter, processes, again through audio sample device, Single-chip Controlling section processes after wireless transmitter module is transmitted into sound receives and the processing section.After the wireless receiving module of sound reception and processing section receives signal, change signal over to the Single-chip Controlling section processes, after treatment, the signal input display is converted into pictorial display, the broadcast of audio frequency broadcast part with beats, frequency of respiration, provide preliminary conclusion simultaneously, and on display screen, show.The computer interface part is transferred to computer with signal and handles.

This utility model compared with prior art has the following advantages:

1, adopts wireless transmission, and combine, realized remote transmission and can do post-processed gained information with computer.

2, the acoustical signal that collects is transformed into figure signal after processing and amplifying, and is diagnosed, make and check that diagnosis is more directly perceived, analyze more convenient.

3, intelligent diagnostics.Analyze by sound, provide preliminary conclusion, and on display screen, show gained, as bradycardia, tachycardia, arrhythmia, breathed short, respiratory gas dyspnea etc.

4, adopt the Bluetooth transmission technology, and be furnished with high pass filter, make transmission more stable, better effects if.

5, adopt wireless transmission, can realize that many people receive simultaneously, help the consultation of doctors and teaching.While has eliminated and has used earphone to make the uncomfortable influence that reaches ear of people owing to adopt wireless transmission to combine with pictorial display.

6, because delicate structure is easy to use, be easy to diagnosis, help the use of family, so very big practical and popularizing value is arranged.

Description of drawings
