Description
Technical field
This utility model relates to a kind of instant playback formula digital sphygmomanometer based on the audio monitoring technology.
Background technology
Data shows according to the relevent statistics, and the existing hyperpietic of China has reached 100,000,000, and annual newly-increased number is more than 3,000,000.From hypertensive harm, hypertension has become human No.1 stealthy killer.Hypertension is a kind of chronic disease of long-term hazards health still not, and it still is the chief culprit of diseases such as apoplexy, coronary heart disease, myocardial infarction, heart failure, renal failure, therefore is called by people " invisible killer ".
The treatment hypertension at first is to measure blood pressure exactly.The instrument of measuring blood pressure is called sphygomanometer.Sphygomanometer can be divided into two kinds of direct-type and indirect types.The operation principle of two kinds of sphygomanometers is inequality, and direct-type is to change with the direct gaging pressure of pressure transducer; The operation principle of indirect type then is that control is applied to the pressure on the tested position from the outside, and the generation of the relative Ke Shi sound of the result that will control and the information of disappearance are judged.No matter but the former is to tremulous pulse or vein follow-on test, and the latter can only measure the systolic pressure and the diastolic pressure of tremulous pulse.
Blood pressure at present commonly used on the market is in respect of three kinds of mercury column sphygmomanometer, air pressure meter type blood pressure meter and electric sphygmomanometers.
Mercury sphygmomanometer than electric sphygmomanometer and meter type blood pressure meter accurately and safety, the whole world is general, is considered to " goldstandard " of blood pressure determination.But mercury column sphygmomanometer is had relatively high expectations to operating technology, and mercurous, if mishandling, can become hospital, family's primary pollution source, generally is applicable to hospital and clinic.Contain pollution and the very big hydrargyrum of toxicity owing to contain mercury thermometer, in recent years, restriction and denial measure have been taked to the supply and the use of hydrargyrum one after another in countries in the world.2007, European Parliament forbade that through legislation EU countries's use contains mercury thermometer.To the end of the year in 2007, the U.S. had 13 states to ban use of through legislation to contain mercury thermometer, medical system then buy safer succedaneum.In the 25th management of united nations environment plan (UNEP) director meeting that in February, 2009, held in Kenya Nairobi; The various countries environment minister reaches common understanding: United Nations Environment Programme will hold 5 government-to-government talks committee series meetings in 2010 in the period of to 2013, and plan to reach in 2013 international mercury pollution control pact.That is to say that after traditional mercurial sphygmomanometer was discarded, the sphygomanometer of other form was with comprehensive occuping market.
The air pressure meter type blood pressure meter utilizes pulsometer operation pressure measurement, and its volume is little; Easy to carry, and do not have the shortcoming that hydrargyrum leaks, but along with the increase of number of applications; Can be because of form of springs changes the accuracy that influences the result, so need the mercury column sphygmomanometer of regular and standard to calibrate.
The electric sphygmomanometer outward appearance is light and handy, and is easy to carry, operates simple and easyly, shows clearly, relatively is fit to general family and uses.Electric sphygmomanometer mainly adopts oscillographic method to realize no-invasive measurement of blood pressure.Utilize electronic pressure transmitter to differentiate, put down in writing pressure and pulse signal in the blood pressure measurement process, handle, finally draw compression and press and diastolic pressure through the algorithm routine of clinical textual criticism.The deficiency of this sphygomanometer is exactly a complex algorithm, and the variation with condition produces bigger measurement error easily.Commercially available electric sphygmomanometer as distinguishing by the measuring point, can be divided into wrist formula and last arm-type; As dividing, can be divided into full rotation type and auto-manual system by metering system.Comparatively speaking, wrist formula electric sphygmomanometer is accurate not as good as last arm-type electric sphygmomanometer, and price is also more expensive.
This shows that it is extremely urgent to develop the convenient and practical sphygomanometer of a kind of novel environment friendly.
The utility model content
This utility model technical issues that need to address just are to overcome existing three kinds of sphygomanometers and pollute big, complex algorithm, measurement error and change with condition and wait defective greatly, and a kind of instant playback formula digital sphygmomanometer based on the audio monitoring technology is provided.It is transformed on traditional sphygomanometer basis, and retention balloon, cuff carry out instant numeral to blood pressure measurement and show, and then replace loaded down with trivial details traditional mechanical pointer header and hydrargyrum pillar indicator unit.Its adopts novel pressure pick off and single-chip microcomputer, and the pressure signal data are carried out transfer of data, sampling and processing, and dynamic accurate monitoring blood pressure is with low cost, simple to operate, function is novel, be easy to carry, and possesses good clinical practice and market popularization value.But the layman is self-help operation also, easily obtains blood pressure sign parameter.
For addressing the above problem, this utility model adopts following technical scheme:
This utility model provides a kind of instant playback formula digital sphygmomanometer based on the audio monitoring technology; Said sphygomanometer is made up of blood pressure pressure acquisition and processing unit and heart beating sound monitoring circuit; Said blood pressure pressure acquisition and processing unit are made up of sphygomanometer cuff, air bag, airway, pressure transducer and single-chip microcomputer, and said sphygomanometer cuff connects air bag and airway, connect pressure transducer through airway; Pressure transducer is connected with single-chip microcomputer; Single-chip microcomputer connects a display driver circuit, and said heart beating sound monitoring circuit comprises the microphony audiomonitor, and said microphony audiomonitor connects a solid state power amplifier; Said solid state power amplifier connects heart beating sound public address loudspeaker, and said microphony audiomonitor is installed in the sphygomanometer cuff.
Said pressure transducer is connected with single-chip microcomputer with the A/D change-over circuit through operational amplifier, and single-chip microcomputer connects the circuit that the A/D change-over circuit is calibrated.
Said display driver circuit comprises the light-emitting diode display drive circuit that is connected with single-chip microcomputer, and the light-emitting diode display drive circuit connects the light-emitting diode display of instant playback blood pressure readings.
Said single-chip microcomputer connects and resets and crystal oscillating circuit, said reset and crystal oscillating circuit comprises reset switch, reset circuit and crystal oscillating circuit, and said crystal oscillating circuit is connected with single-chip microcomputer, and said reset circuit is connected with reset switch respectively with single-chip microcomputer.
