Description
[technical field]
The present invention relates to a kind of electric sphygmomanometer and display packing thereof, refer in particular to a kind ofly, be used electric sphygmomanometer and the display packing thereof that stethoscope accurately reads blood pressure values for the gauger by liquid crystal indicator simulation mercury column display of blood pressure change in value state.
[background technology]
Carry out traditionally human blood-pressure when measuring the most normal use be desk-top mercurial sphygmomanometer, its using method is, cuff is twined the upper arm place of tying up at the measured, stethoscopic chest piece is placed on the ancon brachial artery, inflate to cuff by ball, mercury column is risen, when mercury pressure surpasses systolic pressure (when for example the superb supercontraction of post presses 20～30mmHg), cuff pressure blocking-up upper arm artery blood flow, pulse sound disappears.Stop inflation this moment, opens drain tap venting, and mercury column descends, and when gas pressure in the cuff drops to when equating with systolic pressure, blood can pass through oppressed upper arm blood vessel under the cardiac contractile force effect.Therefore hear from stethoscope that mercury column indication scale is systolic pressure when beating for first.The sound of beating subsequently exists and increases, and reduces to gradually when equating with systolic pressure when the cuff internal pressure, and the sound of beating dies down suddenly or disappears, and mercury column indication scale is a diastolic pressure at this moment.This mercurial sphygmomanometer have tolerance accurately, stablize durable advantage, be a kind of blood pressure measuring device that is most widely used for a long time.Yet, because hydrargyrum is a kind of heavy metal with severe contamination and toxic, human body and environment are all had sizable harm, disabled in many countries and regions at present.
Another kind of blood pressure measuring device commonly used is an electronic digital sphygmomanometer, comprise semiautomatic electronic digital measuring apparatus and full-automatic digital survey meter of blood pressure, wherein semiautomatic electronic numeral survey meter of blood pressure needs the operator to push ball so that cuff is inflated with hands, fully automatic electric sub-figure survey meter of blood pressure is then inflated to cuff by circuit control air pump, exits by circuit controling electromagnetic valve.This electric sphygmomanometer is that the gas pressure vibration that utilizes pressure transducer to detect in the cuff involves pressure, change the different wave of oscillation of corresponding generation according to the cuff internal pressure, indirectly ask for systolic pressure and diastolic pressure by central processing unit through computing by certain method, and by liquid crystal display screen display of blood pressure value and pulse value.As Chinese utility model patent the 99236693.3rd and No. 00240652.7 disclosed electronic digit blood pressure measuring device, detect measured's blood pressure signal and, the mode of measurement result with numerical value directly is presented on the LCDs by pressure transducer through the central processing unit calculation process.And at No. the 00218510.5th, Chinese utility model patent and United States Patent (USP) the 6th, 168,567 and 6,699, wait in the patent documentation for No. 196, disclosed several mercury columns that utilize liquid crystal (or light emitting diode) display screen to simulate traditional mercurial sphygmomanometer and indicated blood pressure values and be aided with the electronic digit blood pressure measuring device that numerical value shows.
For the electric sphygmomanometer that need not adopt direct numerical value to show by stethoscope; its numerical value generally is to obtain indirectly through after certain mathematical method computing; for example use fitting process, rule of three or additive method; Different Individual is had diversity, therefore can not guarantee to obtain accurate blood pressure values.And on price, electric sphygmomanometer is about ten times of common desk-top mercurial sphygmomanometer.And adopt the electric sphygmomanometer of LCDs simulation mercury column indication blood pressure values, can cooperate stethoscopic use simultaneously and obtain accurate blood pressure values, and be accepted by medical personnel and ordinary consumer also easier traditionally.But in the design of the electric sphygmomanometer of aforementioned simulation mercury column indication blood pressure values, the scale of virtual mercury column is to copy the mercury column scale of existing mercurial sphygmomanometer to design, generally be designed to 0～300mmHg, if represent 1mmHg as a scale unit with 1mm, then the entire length of virtual mercury column reaches 30cm, need to adopt the LCDs of size more than 30cm to show, this must cause the LCDs of this type of electric sphygmomanometer oversize, because overlength or super wide liquid crystal display screen are compared its price with the liquid crystal display screen of stock size and are differed greatly, thereby the expensive and high price that causes sphygomanometer, outward appearance is also too heavy, is difficult to realize industrialization.Even if represent 2mmHg as a scale unit with 1mm, the size of LCDs is also at least more than 15cm, and this moment, graduated resolution was relatively poor, and user is difficult for seeing clearly scale.And as No. the 00218510.5th, Chinese utility model patent and United States Patent (USP) the 6th, 168, the mode of the more high range unit (1mm represents 5mmHg) that is adopted in No. 567, though the effect that can reach miniaturization and reduce cost, but be cost with the measuring accuracy that brings high blood pressure down, obviously, this mode is not a best mode.

Fig. 3 is a scale segment length and to represent 1mmHg with 1mm be example as a scale unit with 100mmHg, and with simulation mercury column scale as the simulated pressure scale, shown the gas replenishment process segmentation displaying principle of electric sphygmomanometer of the present invention.Behind the starting switch key 51, inflate by 1 pair of air bag 2 of ball, as shown in Figure 4, this moment, LCDs 4 demonstrated the first scale section 421 (0-100mmHg) of simulation mercury column scale, pressure transducer 31 carries out calculation process with the pressure signal input central processing unit 30 after amplification and A/D conversion that senses, draw pressure value P, and pressure value P compared judgement, if pressure value P is between 0-100mmHg, for example P is 92mmHg, then continue to show the first scale section 421, and be indicated to as explicit identification with simulation mercury column 41 on the corresponding scale of this scale section 421 to show force value.If pressure value P is greater than 100mmHg, judge relatively that then this pressure value P is whether between 100-200mmHg, if judged result is, for example the P value is 188mmHg, then show the second scale section 422 (100mmHg-200mmHg), and be indicated on the corresponding scale of this scale section 422 to show force value, as shown in Figure 5 with simulation mercury column 41.If pressure value P is greater than 200mmHg, judge relatively that then this pressure value P is whether between 200-300mmHg, if judged result is, for example the P value is 233mmHg, then show the 3rd scale section 423 (200mmHg-300mmHg), and be indicated on the corresponding scale of this scale section 423 to show force value, as shown in Figure 6 with simulation mercury column 41.Because the scale of existing mercurial sphygmomanometer is typically designed to 0-300mmHg, therefore it is standard compliant in general implementation process the simulation mercury column scale maximum of analog electronic blood pressure being set at 300mmHg, if pressure value P exceeds the maximum 300mmHg of simulation mercury column scale, then sphygomanometer will send the superpressure alarm signal, for example simulate mercury column 41 and warn, perhaps set up voice device to send voice alarm at measure and control device 3 with the certain frequency flicker.
In the above-described embodiments, be with the form of simulation mercury column as explicit identification, understand easily, in concrete enforcement, also can adopt the explicit identification of other forms, for example sign such as box-shaped vernier, arrow-shaped pointer form.
Fig. 7 is a scale segment length with 100mmHg still and represents that with 1mm 1mmHg is an example as a scale unit, has shown the segmentation displaying principle of electric sphygmomanometer deflation course of the present invention.Along with gas is at the uniform velocity discharged from drain tap 11, pressure value P descends gradually, with similar process shown in Figure 3 be, pressure value P is compared judgement, determine pressure value P drops in which numerical range among 200-300mmHg, 100-200mmHg, the 0-100mmHg, thereby correspondingly show corresponding the 3rd scale section 423, the second scale section 422 or the first scale section 421 by liquid crystal display drive circuit 34 control LCDs 4, respectively as Fig. 6, Fig. 5 and shown in Figure 4, and make simulation mercury column 41 drop to corresponding scale with force value.In this process, the same with the occupation mode of traditional mercurial sphygmomanometer, the operator can use the pulse signal of stethoscope test the measured and read systolic pressure and diastolic pressure according to the Ke Shi sound of hearing from LCDs from stethoscope.
For making things convenient for user to select simulation mercury column scale segment length according to concrete condition in use, for example, be a scale segment length with 200mmHg, the present invention is provided with scale options button 52 for the user operation, as shown in Figure 1.Seeing also shown in Figure 8 is the flow chart of electric sphygmomanometer scale section selection function of the present invention, after entering beginning, program judges whether this scale options button 52 is pressed, if judged result is for denying, show that then user does not change the intention of scale segment length, EP (end of program); If judged result is to show that user is intended to change scale segment length, determines further then whether the scale segment length of setting is 100mmHg at present, if, then the scale segment length is set at another numerical value, for example 200mmHg or 300mmHg, and termination routine; If not, then at present the scale segment length of other numerical value changes and is made as 100mmHg, and termination routine.Understand easily, more than only be to illustrate its function selecting principle, in concrete enforcement, more kinds of scale hop count values can also be set and select, and be not limited to above-mentioned two kinds for user.In fact, if with 200mmHg is a scale segment length, represent 2mmHg as a scale unit with 1mm, measurement result also meets general international standard, and most of people's systolic pressure is in 200mmHg, when measuring so in most cases the simulation mercury column scale on the LCDs remain on 0-200mmHg scale section, also meet user and particularly get used to using the medical personnel of traditional mercurial sphygmomanometer to read the custom of pressure value for a long time.
Grasp outgassing rate to guarantee accurately to read blood pressure values in order to further facilitate user, the present invention can also be provided with the outgassing rate Presentation Function, as shown in Figure 9, the venting beginning enters the outgassing rate calculation procedure, read initial pressure value P0 and initial time T0, along with the gas discharging, pressure descends, and system judges that whether pressure is less than 30mmHg, if not, then bringing in constant renewal in force value and continue, judged result relatively judges; If judged result is, then stop timing, read timing and stop Tn constantly, calculate the time difference T between Tn and the T0, and the difference P between initial pressure value P0 and the 30mmHg, and calculate outgassing rate, termination routine according to " outgassing rate=P/T ".System directly is presented at result of calculation on the LCDs 4 with digital form, for user reference and grasp, as shown in figure 10.In fact further segmentation of outgassing rate, promptly different time sections can have different outgassing rates.
The present invention's other displaying contents except that the simulation mercury column have further been shown among Figure 10, for example beat pulse cue, pulse frequency and outgassing rate.Because in measuring process, when cuff pressure surpassed the systolic pressure of the measured, cuff pressure can be blocked the upper arm artery blood flow, pulse sound disappears; After stopping inflation and opening drain tap venting, cuff pressure descends, and when cuff pressure drops to when equating with systolic pressure, blood can reappear pulse signal at this moment again by oppressed upper arm blood vessel under the cardiac contractile force effect.By the changing condition of the continuous sensing cuff pressure of pressure transducer and obtain to comprise the pressure history of pulse wave, when pulse wave begins to occur, system shows a beat pulse cue on display screen 4, flicker pulsatile heart shape symbol for example, perhaps also can make it directly send the voice suggestion signal by setting up voice device, the prompting user notes reading blood pressure values.Frequency and the amplitude that can also represent beat pulse with the column bar.Wherein amplitude is relevant with the post height of bar, if represent 100% pulse intensity with 〉=4mmHg, and the bar that is provided with 10 lattice shows, then the demonstration of 5 lattice bars is arranged when pulse intensity during for 2mmHg.By the pulse wave frequency is carried out the pulse frequency that statistical calculation can obtain the measured, and directly be presented on the LCDs 4 with digital form.In addition, abnormal conditions are arranged, can also directly send cues such as " arrhythmia " and be presented on the liquid crystal display screen if in monitoring pulse frequency and intensity process, find the pulse frequency or the intensity of the measured.
Figure 11 and Figure 12 have shown third and fourth kind of embodiment of the present invention respectively, mainly be based on some user and wish to observe more intuitively and to read the requirement of blood pressure values, 0-300mmHg is simulated the mercury column scale be divided into 100mmHg and be a scale segment length, represent three the scale sections of 1mmHg, and be simultaneously displayed on the LCDs 4 as a scale unit with 1mm.During measurement, show force value with the simulation mercury column, for example when force value was 192mmHg, the simulation mercury column appeared in 0-100mmHg and two scale sections of 100-200mmHg simultaneously, and arrives corresponding scale position.In Figure 11, along with the rising of force value, the enhancement direction of simulation mercury column in three scale sections is consistent; And in Figure 12, along with the rising of force value, the simulation enhancement direction of mercury column in the first scale section (0-100mmHg) and the 3rd scale section (200-300mmHg) is opposite with enhancement direction in the second scale section (100-200mmHg).In fact, no matter be which direction, when force value changes, the enhancement of simulation mercury column or contract to move back and all have continuity, can allow user more intuitively observed pressure change procedure and accurately read force value.
