Abstract
The utility model relates to an electronic stethoscope. The stethoscope is a necessary tool for enabling a doctor to diagnose the state of an illness of a patient, and the traditional stethoscope utilizes an acoustic principle and enables the doctor to judge the physiological state in the patient through sound which is amplified and then provided for the doctor. The electronic stethoscope comprises a main frame (2) with a loudspeaker (1), wherein one end of the main frame is connected with a receiver (3), the other end of the main frame is connected with a group of earphones (4), and a circuit control board (5) is arranged in the main frame. The electronic stethoscope is used in the medical field.
Description
Technical field:
this utility model relates to a kind of medical instruments field, is specifically related to a kind of electronic stethoscope.
Background technology:
stethoscope is the essential tool of diagnosis conditions of patients, and traditional stethoscope utilizes Principles of Acoustics, with the intravital sound of patient, offers the doctor through amplifying, and lets the doctor pass through sound and judges the intravital physiological situation of patient.Because its is practical simple, again can the direct reaction practical situation, be still the first-selected instrument of the state of an illness in the diagnosis patient body so far.Along with the continuous development of society's science and technology, the continuous progress of medical procedure, under some special occasions, traditional stethoscope has satisfied not, the needs of aspects such as the medical treatment consultation of doctors, the state of an illness are put on record, research and teaching.
Summary of the invention:
The purpose of
this utility model provides a kind of under the situation that does not influence other patients, the electronic stethoscope of can the several people answering simultaneously.
Above-mentioned purpose realizes through following technical scheme:
a kind of electronic stethoscope, its composition comprises: have the main frame of speaker, described main frame one end connects receiver, and the described main frame other end connects one group of earphone, in the described main frame circuit control panel is housed.
described electronic stethoscope; Described circuit control panel comprises the sound store circuit; Described sound store circuit connects sound collection circuit, audio amplifier circuit and digital counting circuit; Described audio amplifier circuit connects output conversion circuit, and described output conversion circuit connects speaker and earphone, and described sound collection circuit connects described audio amplifier circuit.
Beneficial effect:
1. this utility model can be according to actual needs, carries out the segmentation signal of recording and play sound; By the later stage consultation of doctors and disease progression analysis.
Loudspeaker plays can pass through after 2. the acoustical signal of this utility model amplifies through audio frequency in
, is convenient to many people and listens to simultaneously, does the consultation of doctors or research and teaching and discusses; Can also utilize oscillograph or computer to carry out the demonstration and the analysis of waveform acoustical signal.
3. this utility model set up 3 above earphone jacks, being convenient to does not influence under patient's the situation in the ward, many people listen to same signal simultaneously, for the doctor is with the student great convenience are provided.
but 4. this utility model with sound in traditional patient body directly answer signal dress change into record/processing the signal of telecommunication; The diagnostic mode that has only a doctor to listen to the intravital sound of patient traditional synchronization converts to, the consultation of doctors pattern of can many people monitoring simultaneously.
5. the sound of this utility model record can not have to carry out the medical research and the consultation of doctors and remote diagnosis under patient's situation on the scene; Can the body physiological SoundRec of same patient's different phase be got off, analyze the physiological change in patient treatment stage.
Description of drawings:
accompanying drawing 1 is the structural representation of this product.
accompanying drawing 2 is circuit block diagrams of accompanying drawing 1.
accompanying drawing 3 is circuit diagrams of accompanying drawing 2.
The specific embodiment:
Embodiment 1:
a kind of electronic stethoscope, its composition comprises: have the main frame 2 of speaker 1, described main frame one end connects receiver 3, and the described main frame other end connects one group of earphone 4, and circuit control panel 5 is housed in the described main frame.
Embodiment 2:
Embodiment 3:
this device is provided with two display lamps, and LED1 recording indication, LED2 sound intensity change indication and the digital phonogram hop count that shows.
on receiver, practical at any time record button K1, the sheet of auscultation doctor selects button K2, gathers volume knob RP1.
Main frame is provided with voice storage chip player button K3, live sound or recorded voice permutator K4, and phonogram selects button K5, broadcast sound volume knob K6, broadcast sound volume knob RP3 and speaker and earphone conversion jack K7.
Embodiment 4:
are when 1 termination of permutator K4 is put 3 ends: pick up BM directly imports 3 inputs of IC3 audio frequency power amplifier chip with the signal of gathering,, the output of 5 feet is arranged after power amplification, export by speaker BL or earphone again through the K6 conversion.，
are when 1 termination of permutator K4 is put 2 ends: audio power amplifier circuit will amplify the acoustical signal by speech chip IC1 output.
when K1 is closed, behind the segments by K2 button selection recording, IC1 will carry out segmentation and record to the acoustical signal that collects through BM again.
when the K1 disconnection, when K3 is in closure state, IC1 is in tone playing state, after sheet selects button to select plays clip, by the output of 14 feet, plays through speaker BL or earphone.
sheet selections digital display shows circuit: because we have utilized the sheet of IC1 to select function; After starting the IC1 speech chip; We need know that we are recording is or selects to play which fragment for which fragment, and we are through the dynamic indication of counting/number driving CD40110 realization to the sheet position.K5 figure place sign indicating number reset button.
