Description
Technical field
The invention belongs to medical device technical fields, and in particular to a kind of electronic auscultation device based on NRF.
Background technique
Currently, common stethoscope is passed in ear through metal vibration diaphragm in stethoscope probe, then by the pipeline operatic tunes, doctor
It takes root and is judged according to its sound, this stethoscope occupies main positions in medical diagnosis, played an important role.But
It is this stethoscope is often hung on the neck of doctor, fatigue or uncomfortable is easy to produce, in use, cochlea is often subject to come from
The spring pressure of earphone, is affected to medical staff, has discomfort using more.
Summary of the invention
In view of the above-mentioned deficiencies in the prior art, the technical problem to be solved by the present invention is that providing a kind of structure letter
Electronic auscultation device single, low in cost, easy to use based on nRF2401.
The invention adopts the following technical scheme:
A kind of electronic auscultation device based on NRF, including sound transducer and supra-aural earphone, sound transducer and supra-aural
It is provided with nRF2401 in earphone, is connected for wireless mode, is provided on sound transducer and acquires data for real-time display
Display, in the single-chip microcontroller that is internally provided with of sound transducer, sound transducer and the list being arranged in inside sound transducer
The connection of piece machine.
Further, it is provided with wireless transmitter module in sound transducer, wireless receiving module is provided in earphone, wirelessly
The tranmitting frequency of transmitting module and wireless receiving module to receive frequency identical.
Further, the outside of sound transducer is provided with switch, and switch is connect with wireless transmitter module.
Further, sound transducer successively passes through preamplifier, high-pass filter and audio sample device and single-chip microcontroller
Connection, single-chip microcontroller are connected separately with display and wireless transmitter module, and the sound that display is used to acquire sound transducer passes through
It crosses after single-chip microcontroller is converted into waveform and diagnosis and shows.
Further, high-pass filter is 50Hz filter.
Compared with prior art, the present invention at least has the advantages that
The present invention is based on the electronic auscultation devices of nRF2401, and low energy consumption, are easy to carry everyday use, real using wireless transmission
Show remote transmission, it can be achieved that more people are shared, has been conducive to hold a consultation and impart knowledge to students, it is succinct intuitive using graphical display.
Further, high-pass filter is configured, transmission is more stable, and effect is more preferable.
Below by drawings and examples, technical scheme of the present invention will be described in further detail.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the embodiment of the present invention；
Fig. 2 is stethoscope earphone schematic diagram of the present invention.
Wherein: 1. sound transducers；2. wireless transmitter module；3. switch；4. display；5. earphone；6. wireless receiving mould
Block.
Specific embodiment
Fig. 1 and Fig. 2 are please referred to, the invention discloses a kind of electronic auscultation devices based on NRF, including 1 He of sound transducer
Supra-aural earphone 5 is provided with wireless transmitter module 2 in sound transducer 1, wireless receiving module 6, sound is provided in earphone 5
Sensor 1 and earphone 5 wirelessly connect, and the display for real-time display acquisition data is provided on sound transducer 1
Device 4, wireless transmitter module 2 are connect with the switch 3 being arranged in outside sound transducer 1, control its work by switch 3, wireless to send out
Penetrate the tranmitting frequency of module 2 and wireless receiving module 6 to receive frequency identical.
Sound transducer 1 is successively by preamplifier, high-pass filter, audio sample device and single-chip microcontroller and wireless hair
Penetrate module 2 connection, the sound for that will acquire after treatment, using high pass filter, processes.
Preferably, high-pass filter is 50Hz filter；
Wireless transmitter module 2 and wireless receiving module 6 use nRF2401 chip, for being wirelessly connected computer.
Display 4 is used to show the sound that sound transducer 1 acquires after single-chip microcontroller is converted into waveform and diagnosis
Show.
The above content is merely illustrative of the invention's technical idea, and this does not limit the scope of protection of the present invention, all to press
According to technical idea proposed by the present invention, any changes made on the basis of the technical scheme each falls within claims of the present invention
Protection scope within.
