Example 1
Referring to fig. 1 in combination with fig. 3, fig. 1 is a schematic flow chart of a method for measuring blood pressure according to embodiment 1 of the present invention. The method for measuring blood pressure is applied to a blood pressure measuring device, and the blood pressure measuring device comprises a pressure adjusting device and a detecting device. Specifically, as shown in fig. 1, the method includes the following steps S101 to S103.
S101, controlling the pressure regulating device to increase the pressurizing pressure of the preset first human body part of the user from the preset first pressure at a constant speed.
Specifically, the blood pressure measuring device controls the pressure adjusting device to increase the pressurizing pressure of the preset first human body part of the user from the preset first pressure at a constant speed. The preset first human body part can be an arm, a wrist and other human body parts. The pressure regulating device is used for applying pressure to a preset first human body part.
S102, acquiring a change curve of biological sign data of a preset second human body part of a user through the detection device in the process of increasing the pressurizing pressure at a uniform speed.
Specifically, when the blood flowing out of the heart of the user sequentially flows through the first human body part and the second human body part, so that the pressure regulating device applies pressure to the preset first human body part, the blood flowing through the second human body part from the first human body part is blocked by the pressure, so that the biological sign data of the preset second human body part can be changed, and different pressures can change the biological sign data to different degrees, therefore, in the process of uniformly increasing the pressurizing pressure, the detecting device is used for collecting the change curve of the biological sign data of the preset second human body part of the user. For example, the first human body part is an arm and the second human body part is a wrist or a finger; when the second human body part is a wrist, collecting pulse wave signals of the wrist under the condition that the arm is subjected to pressure increased at a constant speed, and measuring blood pressure through pulse wave signal curves of the wrist; when the second human body part is a finger, under the condition that the arm is subjected to pressure increased at a constant speed, collecting pulse wave signals of the finger and measuring blood pressure through a pulse wave signal curve of the finger, or collecting volume wave signals of the finger and measuring blood pressure through a volume wave signal curve of the finger.
And S103, obtaining inflection point data and zero point data of the change curve, and determining the blood pressure of the user according to the inflection point data and the zero point data.
Specifically, after the blood pressure measuring device collects a change curve of biological sign data of a preset second human body part, inflection point data and zero point data of the change curve are obtained, and the blood pressure of a user is determined according to the inflection point data and the zero point data. Since the pressurizing pressure starts to change in the vital sign data of the second human body part when it increases from zero to a certain degree and disappears in the second human body part when it continues to increase to a higher pressure, the blood pressure of the user can be determined by the inflection point data and the zero point data.
In an embodiment, the vital sign data includes a volume wave signal, the change curve includes a volume wave signal curve, and the acquiring inflection point data and zero point data of the change curve includes:
Obtaining an inflection point value of the volume wave signal curve, and taking the inflection point value of the volume wave signal curve as the inflection point data;
and acquiring a zero value of the volume wave signal curve, and taking the zero value of the volume wave signal curve as the zero data.
In particular, the blood pressure of the user may be determined by the volume wave signal. The blood pressure measuring device acquires the inflection point value of the volume wave signal curve, so that how to acquire the inflection point value of the volume wave signal curve is realized, the slope of the volume wave signal curve is mainly identified through the blood pressure measuring device, then a volume wave signal point with the slope changing from zero to non-zero on the volume wave signal curve is identified, the volume wave signal point with the slope changing from zero to non-zero is the inflection point value of the volume wave signal curve, and then the inflection point value of the volume wave signal curve is used as the inflection point data; and obtaining the zero value of the volume wave signal curve, namely obtaining the zero value of the volume wave signal curve by mainly obtaining a volume wave signal point with the value of zero on the volume wave signal curve, and taking the zero value of the volume wave signal curve as the zero data. As shown in fig. 3, when the pressure applied to the first human body part gradually increases, the volume wave signal of the second human body part changes, and it can be seen that when the pressure increases from zero to a certain pressure, the volume wave signal of the second human body part starts to change, that is, starts to decrease, and when the pressure continues to increase, the volume wave signal of the second human body part continuously decreases, and when the pressure increases to another pressure, the volume wave signal of the second human body part decreases to zero.
In an embodiment, determining the blood pressure of the user according to the inflection point data and the zero point data includes:
obtaining the pressurization pressure corresponding to the inflection point value of the volume wave signal curve to obtain the diastolic pressure of the blood pressure;
Obtaining the pressurizing pressure corresponding to the zero point value of the volume wave signal curve to obtain the systolic pressure of the blood pressure;
and determining the blood pressure of the user according to the diastolic blood pressure of the blood pressure and the systolic blood pressure of the blood pressure.
Specifically, after the blood pressure measuring device obtains the inflection point value of the volume wave signal curve and the zero point value of the volume wave signal curve, the blood pressure measuring device obtains the pressurizing pressure corresponding to the inflection point value of the volume wave signal curve, wherein the pressurizing pressure corresponding to the inflection point value of the volume wave signal curve is the diastolic blood pressure of the blood pressure, and obtains the pressurizing pressure corresponding to the zero point value of the volume wave signal curve, the pressurizing pressure corresponding to the zero point value of the volume wave signal curve is the systolic blood pressure of the blood pressure, and the diastolic blood pressure of the blood pressure and the systolic blood pressure of the blood pressure are the blood pressures of a user.
In an embodiment, the biometric data includes a pulse wave signal, the change curve includes a pulse wave signal curve, and the acquiring inflection point data and zero point data of the change curve includes:

and acquiring a zero value of the pulse wave signal curve, and taking the zero value of the pulse wave signal curve as the zero data.
Specifically, in addition to determining the blood pressure of the user from the volume wave signal, the blood pressure of the user may also be determined from the pulse wave signal. The blood pressure measuring device acquires the inflection point value of the pulse wave signal curve, so that how to acquire the inflection point value of the pulse wave signal curve is realized, the slope of the pulse wave signal curve is mainly identified through the blood pressure measuring device, then pulse wave signal points with the slope being zero to be non-zero are identified on the pulse wave signal curve, the pulse wave signal points with the slope being changed from zero to non-zero are the inflection point value of the pulse wave signal curve, and then the inflection point value of the pulse wave signal curve is used as the inflection point data; and obtaining the zero value of the pulse wave signal curve, namely obtaining a zero value of the pulse wave signal curve by mainly obtaining a zero pulse wave signal point on the pulse wave signal curve, wherein the zero pulse wave signal point is the zero value of the pulse wave signal curve, and taking the zero value of the pulse wave signal curve as the zero data. As shown in fig. 3, when the pressurizing pressure applied to the first human body part gradually increases, the pulse signal of the second human body part changes, and it can be seen that when the pressurizing pressure increases from zero to a certain pressure, the pulse signal of the second human body part starts to change, that is, starts to decrease, and when the pressurizing pressure continues to increase, the pulse signal of the second human body part continuously decreases, and when the pressurizing pressure increases to another pressure, the pulse signal of the second human body part decreases to zero.
In an embodiment, determining the blood pressure of the user according to the inflection point data and the zero point data includes:
obtaining the pressurization pressure corresponding to the inflection point value of the pulse wave signal curve to obtain the diastolic pressure of the blood pressure;
obtaining the pressurizing pressure corresponding to the zero point value of the pulse wave signal curve, and obtaining the systolic pressure of the blood pressure;
and determining the blood pressure of the user according to the diastolic blood pressure of the blood pressure and the systolic blood pressure of the blood pressure.
Specifically, after the blood pressure measuring device obtains the inflection point value of the pulse wave signal curve and the zero point value of the pulse wave signal curve, the blood pressure measuring device obtains the pressurization pressure corresponding to the inflection point value of the pulse wave signal curve, wherein the pressurization pressure corresponding to the inflection point value of the pulse wave signal curve is the diastolic blood pressure of the blood pressure, and obtains the pressurization pressure corresponding to the zero point value of the pulse wave signal curve, the pressurization pressure corresponding to the zero point value of the pulse wave signal curve is the systolic blood pressure of the blood pressure, and the diastolic blood pressure of the blood pressure and the systolic blood pressure of the blood pressure are the blood pressures of a user.
In an embodiment, the vital sign data includes a volume wave signal and a pulse wave signal, the change curve includes a volume wave signal curve and a pulse wave signal curve, and the acquiring inflection point data and zero point data of the change curve includes:
Obtaining the inflection point value of the volume wave signal curve and the inflection point value of the pulse wave signal curve, and taking the inflection point value of the volume wave signal curve and the inflection point value of the pulse wave signal curve as the inflection point data;
And acquiring the zero value of the volume wave signal curve and the zero value of the pulse wave signal curve, and taking the zero value of the volume wave signal curve and the zero value of the pulse wave signal curve as the zero data.
In particular, the blood pressure of the user may also be determined by a combination of the volume wave signal and the pulse wave signal. The blood pressure measuring device obtains the inflection point value of the pulse wave signal curve and the inflection point value of the pulse wave signal curve, and then how to obtain the inflection point value of the pulse wave signal curve and the inflection point value of the pulse wave signal curve, the slope of the pulse wave signal curve is identified mainly through the blood pressure measuring device, the pulse wave signal point with the slope being zero and being non-zero on the pulse wave signal curve is identified, meanwhile, the slope of the volume wave signal curve is identified, the volume wave signal point with the slope being zero and being non-zero on the volume wave signal curve is identified, the inflection point value of the pulse wave signal curve is obtained when the pulse wave signal point with the slope being zero and being non-zero is obtained when the slope being zero, and then the inflection point value of the volume wave signal curve and the inflection point value of the pulse wave signal curve are used as the inflection point data; when the inflection point value of the volume wave signal curve and the inflection point value of the pulse wave signal curve are obtained, the zero point value of the volume wave signal curve and the zero point value of the pulse wave signal curve are obtained, and therefore, how to obtain the zero point value of the volume wave signal curve and the zero point value of the pulse wave signal curve is mainly achieved by obtaining the zero pulse wave signal point on the pulse wave signal curve, wherein the zero pulse signal point is the zero point value of the pulse wave signal curve, meanwhile, the zero volume wave signal point is the zero point value of the volume wave signal curve, and then the zero point value of the volume wave signal curve and the zero point value of the pulse wave signal curve are used as the zero point data.
In an embodiment, the determining the blood pressure of the user according to the inflection point data and the zero point data includes:
acquiring the pressurizing pressure corresponding to the inflection point value of the volume wave signal curve;
The pressurization pressure corresponding to the inflection point value of the volume wave signal curve and the pressurization pressure corresponding to the inflection point value of the pulse wave signal curve are weighted and summed to obtain the diastolic pressure of the blood pressure;

and determining the blood pressure of the user according to the diastolic blood pressure of the blood pressure and the systolic blood pressure of the blood pressure.
Specifically, how to determine the blood pressure of the user according to the combination of the volume wave signal and the pulse wave signal, mainly obtaining the pressurization pressure corresponding to the inflection point value of the volume wave signal curve and the pressurization pressure corresponding to the inflection point value of the pulse wave signal curve through a blood pressure measuring device, and then carrying out weighted summation on the pressurization pressure corresponding to the inflection point value of the volume wave signal curve and the pressurization pressure corresponding to the inflection point value of the pulse wave signal curve to obtain the diastolic blood pressure of the blood pressure; and meanwhile, obtaining the pressurizing pressure corresponding to the zero value of the volume wave signal curve and the pressurizing pressure corresponding to the zero value of the pulse wave signal curve, and then carrying out weighted summation on the pressurizing pressure corresponding to the zero value of the volume wave signal curve and the pressurizing pressure corresponding to the zero value of the pulse wave signal curve to obtain the systolic pressure of the blood pressure, wherein the diastolic pressure of the blood pressure and the systolic pressure of the blood pressure are the blood pressure of a user. Therefore, the blood pressure is measured by matching the index of the volume wave signal with the index of the pulse wave signal, and the effect of further reducing the error of blood pressure measurement by measuring multiple indexes can be achieved.
