Specific embodiment

With reference to the accompanying drawings and examples, the application is described in further detail.It is emphasized that following implement Example is merely to illustrate the application, but scope of the present application is not defined.Likewise, following embodiment is only the portion of the application Point embodiment and not all embodiments, the institute that those of ordinary skill in the art are obtained without creative efforts There are other embodiments, shall fall in the protection scope of this application.

Blood pressure detector embodiment one：

It please refers to Fig.1 to Fig.3, Fig. 1 is the structure diagram of the application blood pressure detector embodiment one, and Fig. 2 is Fig. 1 institutes Show the structure diagram of processor in embodiment, Fig. 3 is that embodiment illustrated in fig. 1 pressure sensor sensitivity during pressing arrives The waveform diagram of pressure.Blood pressure detector 100 includes pressure sensor 110, is arranged bullet with 110 periphery of pressure sensor Property air bag 111 and processor 120.

Embodiment as an optimization, the blood pressure detector 100 can also include the circuit board 130 of fixation, the pressure Force snesor 110, processor 120 are mounted on respectively on circuit board 130, and realize electrical connection.Certainly, in other embodiments, Pressure sensor and processor may not limit setting on circuit boards, other set-up modes can be used and by pressure sensor with locating Device connection is managed, is such as directly fixed on the shell of blood pressure detector, and pressure sensor and processing are realized by electric wire Connection between device etc..

Specifically, which touches the artery position of human body limb at least partly patch.Work as elastic balloon 111 are subject to elastic deformation occurs during the popliteal artery entrapment of human body limb, and the gas pressure in its confined space is caused to change, pressure Force snesor 110 is by the value of the sensitive gas pressure to measure the pressure of the artery position indirectly.Preferably, the elastic balloon 111 be in convex hemispherical, so as to contacted well with the artery position in human body wrist portion, certainly, the shape of elastic balloon 111 It is without being limited thereto, it can play and human body wrist portion artery contact action well.In addition, elastic balloon 111 is by rubber etc. Soft material is made.

Since elastic balloon 111 and the contact area of wrist are very big, for example, contact area is 5~10mm circumferential areas, it is excellent Select 8mm, and the stress of pressure sensor 110 is only related with the pressure in elastic balloon 111, and with 111 surface of elastic balloon The position of stress is unrelated, therefore for measurement artery position precision and insensitive, while to the small variation of measurement posture also not It is sensitive.In other words, in blood pressure measurement, it is not required that active force must act upon the geometric center lines of pressure sensor 110 On, as long as the elastic balloon 111 outside pressure sensor 110 can touch artery position, i.e., the position to stress and Angle is not strict with.This can reduce the operation requirement to user in the case where ensureing measurement accuracy.

Specifically when carrying out blood pressure measurement, artery position (the i.e. human body of artery position of elastic balloon 111 and human body limb Epidermis soft tissue, such as the human epidermal soft tissue of C Pneumoniae position) be affixed it is tactile.Pressure sensing is set with blood pressure detector 100 110 one side of device be used as downside, when gauger from the upside of blood pressure detector 100 apply pressing force, such as the hand pressing force of user When, which acts on pressure sensor 110, and passes through the elastic balloon 111 that periphery is arranged and squeeze the artery position.At this time The sensitive pressure transferred to artery position by elastic balloon 111 of pressure sensor 110, wherein pressure is specially the anti-of pressing force The pulse pressure of active force and artery position is made a concerted effort.

The artery position calculation of pressure that processor 120 is detected according to pressure sensor 110 by elastic balloon 111 obtains Human blood-pressure value is specific such as the systolic pressure and diastolic pressure of human body.Specifically, the processor 120 is obtained including pressure in the present embodiment Module 121 and blood pressure computing module 122.Wherein, pressure acquisition module 121 connects for synchronous obtain in blood pressure detector 100 Pressure sensor detects the pressure of artery position during by external pressing force, obtains continuous pressure signal, and blood pressure calculates Module 122 then obtains the systolic pressure and diastolic pressure of artery position according to the pressure signal.

It is touched for example, gauger pastes elastic balloon 111 near artery position, and presses blood pressure detector 100, In, during pressing, pressing force value changes from small to large, then from big to small.During pressing, pressure acquisition module 121 The pressure that multiple repairing weld pressure sensor 110 detects forms continuous pressure signal (as schemed by all pressure values sampled Shown in 3).Since in whole process is pressed, artery position blood flow experienced from unimpeded to blocking, then from blocking unimpeded, the phase Between pressing force increase and reduce during experienced pressing force equal to systolic pressure, diastolic pressure at the time of (in pressure process T1, t2, t3, t4 in pressure reduction), thus can the single pressure signal according to pressurization or pressure reduction pressure value is calculated, Or two groups of pressure values are respectively obtained according to pressurizeing and being depressured two processes, it is worth to more accurately human blood-pressure by two groups of blood pressures Value.Blood pressure computing module 122 obtains the pressure signal during pressing force increases and ors reduce, using wave character method or Person's amplitude characteristic ratios method differentiates from the pressure signal obtains the systolic pressure and diastolic pressure of gauger's human body.It should be noted that ripple Shape characteristic method differentiates blood pressure by identifying wave character of the pressure wave at systolic pressure and diastolic pressure, and amplitude characteristic ratios method is i.e. logical It crosses and determines and recognize the relation between systolic pressure amplitude, diastolic pressure amplitude and amplitude peak to differentiate blood pressure.Due to specifically obtaining Artery position pressure signal during pressing obtains systolic pressure and diastolic pressure belongs to the prior art, does not illustrate herein.

For example, in the present embodiment, the specific method that human blood-pressure value is calculated in processor is：The pressure acquisition module It is additionally operable to obtain the pressure that the pressure sensor detects when the blood pressure detector does not receive external pressing force, obtain Obtain the pulse pressure signal for continuously including at least a pulse cycle；

The blood pressure computing module is specifically used for the cycle for obtaining pulse pressure signal, using the cycle to being pressed described Pressure is increased and ord reduce after the pressure signal obtained in the process is filtered, by the ripple of the filtered pressure signal Occur systolic pressure of the higher value in two moment corresponding pressure values of the whole story shaken as artery position in shape, smaller value is made For the diastolic pressure of artery position.

Wherein, pressure acquisition module 121, can be by sample circuit or by micro- when obtaining pressure signal by sampling Type computer MCU performs the digital pressure that computer program is realized or 121 obstructed over-sampling mode of pressure acquisition module obtains Signal, the output terminal for being directly connected to pressure sensor obtains simulated pressure signal, herein not to how to obtain continuous pressure signal It defines.

Preferably, pressure sensor uses pressure sensor in higher sensitivity, such as silicon piezoresistance type pressure in the present embodiment Force snesor, silicon piezoresistance type pressure sensor inside include silicon chip electric bridge, MIniature machinery structure, adc circuit, temperature sensing structure And serial line interface etc., specific principle are well known to those skilled in the art with the course of work, details are not described herein again.The pressure Sensor installation dimension is small, for example can be less than 9 × 9mm.Alternatively, requiring the embodiment of compact another, pressure passes The smaller pressure sensor of installation dimension may be employed in sensor, to make the overall structure of blood pressure detector more compact, just It takes, for example with film piezoresistive pressure sensor, installation dimension can be less than 6 × 6mm.In addition, implement according to the present invention The needs of example can also customize smaller pressure sensor.

For example, gauger touches elastic balloon patch near artery position, and press blood pressure detector, wherein, by During pressure, pressing force value changes from small to large, then from big to small.During pressing, the processor of blood pressure detector leads to The pressure of multiple sampled pressure sensor output is crossed, continuous pressure signal is formed (such as Fig. 3 institutes by all pressure values sampled Show).Since in whole process is pressed, artery position blood flow experienced from unimpeded to blocking, then from blocking to unimpeded, during which exist At the time of pressing force increases and experienced pressing force during reducing equal to systolic pressure, diastolic pressure (t1 in pressure process, T2, t3, t4 in pressure reduction), thus can the single pressure signal according to pressurization either pressure reduction be calculated pressure value or Two groups of pressure values are respectively obtained according to pressurizeing and being depressured two processes, more accurately human blood-pressure value is worth to by two groups of blood pressures.

Processor obtains the pressure signal during pressing force increases and ors reduce, using wave character method or width Degree Y-factor method Y differentiates from the pressure signal obtains the systolic pressure and diastolic pressure of gauger's human body.In the present embodiment, processor root The specific method for differentiating to obtain pressure value according to pressure signal is：Institute during processor obtains the pressing force increase or reduces The pressure signal obtained, the waveform of the pressure signal obtained according to this in pressurization or pressure reduction establish coenvelope respectively Line, baseline and lower envelope line, wherein, the peak value for pressing the periodic pressure signal obtained in the process is connected to obtain coenvelope Line, valley connect to obtain lower envelope line；Processor finds out the first inflection point and Second Inflexion Point of the lower envelope line and baseline, will Systolic pressure of the maximum of the first inflection point corresponding pressure signal as artery position believes the Second Inflexion Point corresponding pressure Number diastolic pressure of the maximum as artery position.Processor, will be above-mentioned further according to blood pressure ratio between heart and artery position The pressure value of measurement is scaled the height pressure value that heart goes out.Since the blood pressure conversion between wrist and heart is known in the art Common sense, therefore do not illustrate, also, in embodiment below, after the height blood values that artery position measures are obtained, write from memory Recognize the step of execution is scaled height pressure value at heart.

It should be noted that when for measuring blood pressure, to make the pressure signal of measurement more accurate, the sampling week of processor Phase is arranged to millisecond (ms), is, for example, 1~10ms, is preferably 2ms, and the time of grip pressure is more than 4 seconds, is, for example, 6s, that Every pressure value data of change curve during pressing have 6000/2=3000 points, during which at least experienced 3~6 it is complete Whole heart beat cycle, and each heart beat cycle at least 500 sampled datas, greatly improve the accurate of each heartbeat signal Degree so that the actual heart beat cycle or blood pressure that can be relatively accurately calculated merely with 3~6 heartbeat signals.It can be seen that the application The measurement of 6s is taken than conventional method hundreds of seconds, shortens tens times.

The present embodiment obtains accurate pressure signal by peripheral hardware elastic balloon and using pressure sensor sensitive enough, It is higher due to measuring obtained pressure signal accuracy, therefore can pressure value directly be obtained by simple algorithm, greatly reduce fortune Calculation amount and operation time.Traditional air-pump type blood pressure detector is different from, the application using elastic balloon due to improving pressure The accuracy of force signal, without expending the excessive time, it is only necessary to can obtain accurate pressure value for several seconds, such as the several seconds is pressed with hand The measurement of pressure value can be realized.Moreover, can directly be measured using hand held, the air bag without setting aeration is gentle Pump, greatly reduces volume and weight so that detection device lighting.Further, since the application blood pressure detector is light Just, Wrist wearable type is may be configured as, it can be achieved that detecting human pulse, blood pressure situation in real time.

In addition, further need to slowly deflate in pressure reduction better than existing air-pump type sphygmomanometer measures blood pressure method, Due in external pressing force increase (pressurization) and when reducing (decompression) pressing force is equal to systolic pressure or diastolic pressure in the process, and this Shen It please pressurizes without air pump aerating, therefore influence of noise blood pressure measurement will not be generated, therefore the application can be chosen in pressurization or decompression One process measurement blood pressure can choose pressurization and decompression process and measures both sides pressure value respectively simultaneously, pass through average value Obtain more accurate pressure value.
