【Embodiment】

With reference to the accompanying drawings and examples, the application is described in further detail.It is emphasized that Following examples are merely to illustrate the application, but scope of the present application are not defined.Likewise, following Embodiment is only the section Example of the application and not all embodiments, and those of ordinary skill in the art are not having The all other embodiment obtained under the premise of creative work is made, the scope of the application protection is belonged to.

Blood pressure detector embodiment one：

Fig. 1 to Fig. 3 is referred to, Fig. 1 is the structural representation of the application blood pressure detector embodiment one, schemed 2 be the structural representation of processor in embodiment illustrated in fig. 1, and Fig. 3 is embodiment illustrated in fig. 1 in pressing process The waveform diagram for the pressure that middle pressure sensor sensitivity is arrived.Blood pressure detector 100 includes pressure sensor 110th, the elastic bag 111 and processor 120 with the periphery of pressure sensor 110 are arranged.

As optimal enforcement example, the blood pressure detector 100 can also include the circuit board 130 of fixation, The pressure sensor 110, processor 120 are mounted on circuit board 130 respectively, and realize electrical connection.Certainly, In other embodiments, pressure sensor and processor may not limit setting on circuit boards, can use other Pressure sensor is simultaneously connected by set-up mode with processor, is such as directly fixedly installed on the outer of blood pressure detector On shell, and realize by electric wire connection between pressure sensor and processor etc..

Specifically, the elastic bag 111 is used at least partly paste the artery position for touching human body limb.Work as bullet Property air bag 111 by human body limb popliteal artery entrapment when occur elastic deformation, cause the gas in its confined space Body pressure changes, and pressure sensor 110 is by the value of the sensitive gas pressure to measure the artery indirectly The pressure of position.Preferably, the elastic bag 111 be in convex hemispherical, so as to human body wrist portion Artery position is contacted well, certainly, the shape not limited to this of elastic bag 111, can be played and human body Wrist portion artery contact action well.In addition, elastic bag 111 is made up of soft materials such as rubber.

Because elastic bag 111 and the contact area of wrist are very big, for example, contact area is justified for 5~10mm All areas, preferably 8mm, and the stress of pressure sensor 110 only has with the pressure in elastic bag 111 Close, and it is unrelated with the position of the surface stress of elastic bag 111, therefore for measurement artery position precision not Sensitivity, while the change small to measurement posture is also insensitive.In other words, in blood pressure measurement, not It is required that active force must act upon in the geometric center lines of pressure sensor 110, as long as pressure sensor 110 It is not tight that outside elastic bag 111 can touch artery position, the i.e. position to stress and angle Lattice requirement.This just can reduce the operation requirement to user in the case where ensureing measurement accuracy.

It is specific when carrying out blood pressure measurement, the artery position of elastic bag 111 and human body limb (i.e. artery The human epidermal soft tissue of the human epidermal soft tissue put, such as C Pneumoniae position) be affixed it is tactile.With blood pressure detecting Device 100 sets the side of pressure sensor 110 as downside, when gauger is from blood pressure detector 100 Upside applies pressing force, and during the hand pressing force of such as user, the pressing force acts on pressure sensor 110, and The elastic bag 111 being arranged by periphery extrudes the artery position.Now pressure sensor 110 is sensitive arrives artery The pressure that position is transmitted by elastic bag 111, wherein pressure are specially the reaction force of pressing force and moved The pulse pressure of arteries and veins position make a concerted effort.

The artery position pressure that processor 120 is detected according to pressure sensor 110 by elastic bag 111 Calculating obtains human blood-pressure value, specific such as the systolic pressure and diastolic pressure of human body.Specifically, at this in the present embodiment Managing device 120 includes pressure acquisition module 121 and blood pressure computing module 122.Wherein, pressure acquisition module 121 Detected for synchronous acquisition pressure sensor during blood pressure detector 100 receives outside pressing force dynamic The pressure of arteries and veins position, obtains continuous pressure signal, blood pressure computing module 122 is then according to the pressure signal Obtain the systolic pressure and diastolic pressure of artery position.

Touched for example, gauger pastes elastic bag 111 near artery position, and press blood pressure detector 100, wherein, during pressing, pressing force value changes from small to large, then from big to small.In pressing process In, the pressure that the multiple repairing weld pressure sensor 110 of pressure acquisition module 121 is detected, by the institute sampled Continuous pressure signal (as shown in Figure 3) is constituted by pressure value.Due to pressing whole process in, artery Position blood flow experienced from unimpeded to blocking, then from blocking to unimpeded, during which increase and reduced in pressing force (t1, t2 in pressure process, decompression at the time of pressing force is experienced in journey equal to systolic pressure, diastolic pressure During t3, t4), therefore can it is single according to pressurization or pressure reduction pressure signal calculate obtain pressure value, Or two groups of pressure values are respectively obtained according to pressurizeing and being depressured two processes, it is worth to more accurately by two groups of blood pressures Human blood-pressure value.Blood pressure computing module 122 obtains the pressure letter during pressing force increases and/or reduces Number, the receipts for obtaining gauger's human body are differentiated from the pressure signal using wave character method or amplitude characteristic ratios method Contractive pressure and diastolic pressure.It should be noted that wave character method is i.e. by recognizing pressure wave in systolic pressure and diastole Wave character at pressure differentiates blood pressure, and amplitude characteristic ratios method is i.e. by determining and recognizing systolic pressure amplitude, diastole Relation between pressure amplitude degree and amplitude peak differentiates blood pressure.Due to the artery position during specific pressed Put that pressure signal obtains systolic pressure and diastolic pressure belongs to prior art, do not illustrate herein.

For example, in the present embodiment, the specific method that processor calculating obtains human blood-pressure value is：The pressure Acquisition module is additionally operable to obtain the pressure sensing when the blood pressure detector does not receive outside pressing force The pressure that device is detected, obtaining continuously at least includes the pulse pressure signal of a pulse cycle；

The blood pressure computing module specifically for obtain pulse pressure signal cycle, using the cycle to After the pressure signal obtained during the pressing force increase and/or reduction is filtered, after this is filtered Pressure signal waveform in there is higher value in two moment of the whole story corresponding pressure value for shaking as dynamic The systolic pressure of arteries and veins position, smaller value as artery position diastolic pressure.

Wherein, pressure acquisition module 121 can pass through sample circuit when obtaining pressure signal by sampling Computer program realization or pressure acquisition module 121 are either performed not by adopting by microcomputer MCU The digital pressure signal that sample loading mode is obtained, the output end for being directly connected to pressure sensor obtains simulated pressure signal, Do not defined herein to how to obtain continuous pressure signal.

Preferably, pressure sensor uses pressure sensor in higher sensitivity, such as silicon pressure in the present embodiment Include silicon chip electric bridge, MIniature machinery structure, ADC inside resistance pressure transducer, silicon piezoresistance type pressure sensor Circuit, temperature sensing structure and serial line interface etc., its specific principle are people in the art with the course of work Member is known, and here is omitted.The pressure sensor installation dimension is small, such as can be less than 9 × 9mm. Or, require the embodiment of compact another, pressure sensor can be smaller using installation dimension Pressure sensor, to make the overall structure of blood pressure detector more compact, portable, for example with film Piezoresistive pressure sensor, its installation dimension can be less than 6 × 6mm.In addition, according to embodiments of the present invention Need that smaller pressure sensor can also be customized.

The embodiment one of blood pressure measuring method：

Referring to Fig. 9, Fig. 9 is the flow chart of the application blood pressure measuring method embodiment one.In the present embodiment Blood pressure detector of the blood pressure detector as described in above example, therefore not to repeat here.This blood pressure measurement Method comprises the following steps：

Step S901：The pressing force outside the receiving of the blood pressure detector of user's limbs is sheathed on, wherein, institute The pressure sensor that blood pressure detector sets periphery to be arranged with elastic bag is stated, the pressure sensor passes through The elastic bag that periphery is arranged extrudes the artery position of human body limb.

For example, gauger by the elastic bag of blood pressure detector at least partly and wrist portion arteries and veins position be affixed it is tactile, To ensure that pressure sensor can sense the pressure that artery position is produced by the elastic bag, and it is another Hand pressing blood pressure detector several seconds, such as 4~10 seconds, preferably 6 seconds.Press what is produced by another hand The change of pressing force, from pine to tight, the blood flow of wrist artery is from unimpeded to blocking, and then upper pressure is again from being tightened to Unclamp, the blood flow of wrist artery is again from blocking to unimpeded, it is ensured that can measure the high and low pressure value of gauger. The elastic bag that the pressure sensor is arranged by periphery extrudes the artery position of human body limb so that the artery Position produces pressure in pressing to elastic bag.

Step S902：Pressure sensor persistently carries out pressure detecting.

Pressure sensor is sensitive during pressing to arrive the lower pressure from artery position, wherein, the lower pressure Reaction force and pulse pressure for pressing force are made a concerted effort.

Step S903：The calculation of pressure that blood pressure detector is exported according to the pressure sensor obtains human body blood Pressure value.

For example, gauger touches elastic bag patch near artery position, and blood pressure detector is pressed, its In, during pressing, pressing force value changes from small to large, then from big to small.During pressing, blood The pressure that the processor of pressure detection means is exported by multiple repairing weld pressure sensor, by all pressures sampled Force value constitutes continuous pressure signal (as shown in Figure 3).Due to pressing whole process in, artery position blood Stream experienced from unimpeded to blocking, then from blocking to unimpeded, it is during which equal during pressing force increases and reduces At the time of pressing force be experienced equal to systolic pressure, diastolic pressure (in t1, t2 in pressure process, pressure reduction T3, t4), therefore can it is single according to pressurization or pressure reduction pressure signal calculate obtain pressure value, Huo Zhegen Two groups of pressure values are respectively obtained according to pressurizeing and being depressured two processes, more accurately human body blood is worth to by two groups of blood pressures Pressure value.

Processor obtains the pressure signal during pressing force increases and/or reduces, using wave character method or Person's amplitude characteristic ratios method differentiates the systolic pressure and diastolic pressure for obtaining gauger's human body from the pressure signal.This implementation In example, processor differentiates that the specific method for obtaining pressure value is according to pressure signal：Processor is pressed described in obtaining The pressure signal obtained in pressure increase or reduction process, is obtained according to this in pressurization or pressure reduction To the waveform of pressure signal set up coenvelope line, baseline and lower envelope line respectively, wherein, process will be pressed The peak value connection of the periodic pressure signal of middle acquisition obtains coenvelope line, and valley connection obtains lower envelope line； Processor finds out the first flex point and Second Inflexion Point of the lower envelope line and baseline, by first flex point pair The maximum of pressure signal is answered as the systolic pressure of artery position, by the Second Inflexion Point corresponding pressure signal Maximum as artery position diastolic pressure.Processor further according to blood pressure ratio between heart and artery position, The pressure value of above-mentioned measurement is scaled the height pressure value that heart goes out.Due to the blood pressure between wrist and heart General knowledge known in this field is scaled, therefore is not illustrated, also, in embodiment below, is being obtained After the height blood values that artery position is measured, the step of acquiescence 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, processor Sampling period be set to millisecond (ms), preferably for example, 1~10ms, 2ms, the time of grip pressure For more than 4 seconds, for example, 6s, then every pressure value data of change curve during pressing have 6000/2=3000 points, during which at least experienced 3~6 complete heart beat cycles, and each heart beat cycle is extremely Rare 500 sampled datas, greatly improve the degree of accuracy of each heartbeat signal so that merely with this 3~6 Actual heart beat cycle or blood pressure that individual heartbeat signal can be accurately calculated relatively.It can be seen that the application 6s measurement consumption When than conventional method hundreds of seconds, shorten tens times.

The present embodiment obtains accurate pressure by peripheral hardware elastic bag and using pressure sensor sensitive enough Signal, the pressure signal accuracy obtained due to measuring is higher, therefore directly can obtain blood pressure by simple algorithm Value, greatly reduces operand and operation time.It is different from traditional air-pump type blood pressure detector, this Shen Please due to using elastic bag to improve the accuracy of pressure signal, without expending the excessive time, it is only necessary to several seconds Accurate pressure value is can obtain, it is the measurement that pressure value can be achieved that the several seconds is for example pressed with hand.Moreover, can Directly measured using hand held, air bag and air pump without setting aeration greatly reduce volume And weight so that detection means lighting.Further, can because the application blood pressure detector is light Wrist wearable type is set to, detection human pulse, blood pressure situation in real time can be achieved.

In addition, further need to slowly be deflated in pressure reduction better than existing air-pump type sphygmomanometer measures blood pressure Method, because pressing force is equal to contraction during outside pressing force increase (pressurization) and reduction (decompression) When pressure or diastolic pressure, and the application pressurizes without air pump aerating, therefore will not produce influence of noise blood pressure measurement, Therefore the application can choose pressurization or decompression in a process measurement blood pressure, or can choose simultaneously pressurization and Decompression process measures both sides pressure value respectively, by being averagely worth to more accurate pressure value.

Because in the outside pressing force of no receiving, the pressure value that pressure sensor is detected is normal arteries and veins Fight pressure value, therefore the pressure signal is pulse pressure signal.

Step S1002：Pressure highest pulse high-voltage value is searched from the pulse pressure signal and pressure is minimum Pulse low voltage value, and calculate the proportionate relationship of the pulse high-voltage value and pulse low voltage value, received as human body The proportionate relationship of contractive pressure and diastolic pressure.

Processor obtains the peak value and valley of pulse pressure signal, calculates the ratio conduct between the peak value and valley Proportionate relationship between pulse high and low pressure value, and then it is used as the proportionate relationship between human body systolic pressure and diastolic pressure.

Step S1003：Pressing force outside blood pressure detector receiving, wherein, the pressure sensor passes through The elastic bag that periphery is arranged extrudes the artery position of human body limb.

Step S1004：The pressure sensor persistently carries out pressure detecting.

Step S1005：Blood pressure detector receives to obtain during outside pressing force in the blood pressure detector The pressure sensor detects the pressure of artery position, obtains continuous pressure signal.

Step S1006：Blood pressure detector the pressing force increase and/or reduction process obtained in institute State pressure signal and calculate the systolic pressure or diastolic pressure for obtaining artery position.Specifically, the processing of blood pressure detector The mode that device obtains pressure value according to the pressure signal is not illustrated herein as described in above example.

Step S1007：Blood pressure detector is according to the human body systolic pressure and the calculating pair of the proportionate relationship of diastolic pressure The diastolic pressure or systolic pressure answered.

For example, the processor of blood pressure detector obtains systolic pressure according to pressure signal, according to systolic pressure and relax The proportionate relationship for opening pressure obtains diastolic pressure.Or processor obtains diastolic pressure, according to systolic pressure and diastolic pressure Proportionate relationship obtains systolic pressure.

The present embodiment uses innovation mode, is obtained by being calculated when not pressing between systolic pressure and diastolic pressure Proportionate relationship, can obtain another pressure value by one of pressure value and proportionate relationship, reduce acquisition The computational complexity of two pressure values.
