Description
Technical field
This utility model relates to a kind of sphygomanometer, is specifically related to a kind of Korotkoff's Sound method environmental protection sphygomanometer towards health care professional.
Background technology
Tradition mercurial sphygmomanometer adopts Korotkoff's Sound method Measure blood pressure, and Korotkoff's Sound method is most popular indirect blood pressure measuring method clinically, is referred to as " goldstandard " of blood pressure measurement.Tradition mercurial sphygmomanometer utilizes mercurypressure difference measurements blood pressure, because it mostly is glass, easily broken, causes hydrargyrum to leak, the safety of harm people.
Oscillographic method electronic sphygmomanometer can not accurately detect individual pressure value in principle, why it can replace Korotkoff's Sound method mercurial sphygmomanometer to be because both are after large-scale experiment measuring, meansigma methods is comparatively close, but concerning individuality, difference is sizable.The test result of some experts and scholars to oscillographic method and Korotkoff's Sound method compares.American Medical Association's magazine (JAMA) statistics draws: just because of the error of 5mmHg in blood pressure measurement, 2,100 ten thousand Americans will be caused to accept unnecessary clinical intervention, and 2,700 ten thousand Americans miss necessary clinical intervention.Because the individual accuracy of oscillographic method is lower, be therefore used for the health care of community and family, be also difficult at present replace the manual blood pressure measurement of clinical traditional Ke Shiyin.
Summary of the invention
For the problems referred to above, the utility model proposes a kind of Korotkoff's Sound method environmental protection sphygomanometer towards health care professional, easy to use, cheap, use the pressure in the slow deflation course of pressure transducer measurement cuff, in conjunction with Korotkoff's Sound method, show in real time on a display screen, on the basis of abandoning mercury column display, realize the Measurement accuracy of blood pressure.
For solving the problem, design of the present utility model is: a kind of Korotkoff's Sound method environmental protection sphygomanometer towards health care professional, comprise the stethoscope for manual detection Korotkoff's Sound signal, the cuff of built-in air cavity, by trachea to the pressue device of cuff inflation and the decompressor giving cuff deflation, for measuring the pressure transducer of pressure in cuff, the LCDs of single-chip microcomputer and connection single-chip microcomputer, also comprise Signal-regulated kinase, the input of pressure transducer connects air cavity in cuff, the input of outfan connection signal conditioning module, the outfan of Signal-regulated kinase connects single-chip microcomputer, described Signal-regulated kinase is frequency divider, described pressure transducer is capacitance pressure transducer, pressure signal being converted into frequency signal.Carry out frequency division by pressure transducer connection frequency divider and export single-chip microcomputer to, this design when not using A/D to carry out digital-to-analogue conversion, can obtain 16bit resolution, simple to operation, cheap, can meet instructions for use preferably; By the real-time display of display, facilitate medical personnel's record.
Preferably, described decompressor is the constant speed vent valve connecting trachea, controls cuff and carries out constant speed venting decompression.
Preferably, the slow venting speed that described decompressor controls cuff is 5mmHg/s, can obtain the pressure waveform under steady air flow speed, avoids venting speed unstable, causes the problem that measured value is not easily determined.
Preferably, described pressure transducer is SEN301 capacitance type sensor, the pressure signal measured in cuff is converted into frequency signal, pressure increase, frequency decrease, and carries out 50 frequency divisions by frequency divider, reach the signal processing condition of 51 single-chip microcomputers.
Use capacitance type sensor to survey pressure in cuff, abandon oscillographic method and measure pulse wave, avoid because individual variation causes the pulse wave amplitude measured to convert the inaccurate problem of pressure value drawn.
Beneficial effect: this utility model, easy to use, simple to operate, cheap, abandoning mercury column display mode, by measuring pressure in cuff, in conjunction with Korotkoff's Sound method, the Measurement accuracy of blood pressure can be realized, safety, environmental protection, be applicable to health care professional and use.
