Abstract
The sound simulation method of the Korotkoff sounds comprises a single chip microcomputer control unit and an audio decoding control unit, wherein the single chip microcomputer control unit transmits collected data to the audio decoding control unit through processing, and the audio decoding control unit simulates the playing frequency and volume of five time phases according to the received data by utilizing low-frequency enhancement and volume control functions. A sound simulation method of Korotkoff sounds controls the volume and frequency of each heart sound before the heart sound is played, so that the characteristics of the Korotkoff sounds in the current time phase are the same. Thereby more realistically simulating the Korotkoff sounds of blood pressure measurement.
Description
Technical field
The present invention relates to a kind of medical teaching field, relate in particular to the speech simulation method in the Ke Shi sound in a kind of blood pressure simulator.
Background technology
Blood pressure measurement is the most general detection method of clinical practice, the doctors and nurses is carried out the blood pressure measurement training have bigger meaning.The blood pressure measuring method of clinical practice at present is Ke Shi sound stethoscopy, adopts mercury mercury gauge sphygmomanometer and stethoscope, through suppressing about the above 40mmHg of high pressure, and venting at a slow speed then.In deflation course, listen to patient's Ke Shi sound with stethoscope and measure blood pressure, but phase when existing blood pressure simulator can not simulate five of Ke Shi sound realistically aspect auscultation tonequality can not be measured systolic pressure and diastolic pressure exactly.
Summary of the invention
In order to address the above problem, the present invention provides Ke Shi sound sound method in a kind of Ke Shi sound simulation blood pressure simulator that adopts real human body, and phase in the time of can simulating five of Ke Shi sound is realistically measured systolic pressure and diastolic pressure exactly.
The technical scheme that the present invention adopts is: a kind of speech simulation method of Ke Shi sound; Comprise Single-chip Controlling unit and audio decoder control module; Described Single-chip Controlling unit sends the data of gathering to the audio decoder control module through processing, mutually broadcast frequency and volume when the audio decoder control module utilizes the data that receive low frequency strengthen to simulate five with volume control function.
Described Single-chip Controlling unit comprises judge module, data processing module; Judge module compares preset force value and the detected force value of pressure transducer; Confirm the cycle that heart is play according to preset heart rate, judge and play the pressure limit that sound is arranged.
The value that described data processing module obtains after will be is relatively handled the back and is passed to audio decoder through spi bus; The cutoff frequency of phase time when judge module is set five respectively, data processing module is handled through spi bus and is passed to audio decoder.
Described audio decoder control module utilizes low frequency to strengthen the data that receive and volume control function is confirmed broadcast frequency and volume before each hear sounds is play.
Beneficial effect of the present invention is that a kind of speech simulation method Ke Shi sound of Ke Shi sound is controlled its volume and frequency before each hear sounds is play, make it identical with Ke Shi sound characteristic of phase when current, thereby simulate the Ke Shi sound of blood pressure measurement more realistically.
