Example 1
Referring to fig. 1, and referring to 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 the blood pressure is applied to a blood pressure measuring device which comprises a pressure adjusting device and a detecting device. Specifically, as shown in FIG. 1, the method includes the following steps S101-S103.
S101, controlling 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.
Specifically, the blood pressure measuring device controls the pressure adjusting device to increase the pressurizing pressure of the 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.
And S102, acquiring a change curve of the biological sign data of a second preset human body part of the user through the detection device in the process of increasing the pressurizing pressure at a constant speed.
Specifically, the blood flow that user's heart flowed out flows through in proper order first human body position and second human body position, thereby makes when pressure regulating device applys pressure for the first human body position of predetermineeing, owing to follow first human body position flows through the blood flow of second human body position is obstructed by pressure, makes the biological sign data of the second human body position of predetermineeing can change, and different pressures can make biological sign data take place the change of different degrees, consequently the in-process that the pressurization pressure at the uniform velocity rose, through detection device gathers the change curve of the biological sign data of the second human body position of user's predetermineeing. 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, under the pressurizing pressure of the arm which rises at a constant speed, collecting a pulse wave signal of the wrist and measuring the blood pressure through a pulse wave signal curve of the wrist; when the second human body part is a finger, under the pressurizing pressure of the arm which is raised at a constant speed, the pulse wave signal of the finger is collected, and the blood pressure is measured through the pulse wave signal curve of the finger, or the volume wave signal of the finger is collected, and the blood pressure is measured through the volume wave signal curve of the finger.
S103, inflection point data and zero point data of the change curve are obtained, and the blood pressure of the user is determined according to the inflection point data and the zero point data.
Specifically, after acquiring a preset change curve of biological sign data of a second human body part, the blood pressure measuring device acquires inflection point data and zero point data of the change curve, and determines the blood pressure of the user according to the inflection point data and the zero point data. Since an increase in the compression pressure from zero to a certain extent will cause the biological data of the second body part to start to change and will cause the biological data of the second body part to disappear as the compression pressure continues to increase to higher pressures, the blood pressure of the user can be determined from the inflection point data as well as the zero point data.
In one embodiment, the biological sign data includes a volume wave signal, the variation curve includes a volume wave signal curve, and the acquiring inflection point data and zero point data of the variation curve includes:
acquiring an inflection point value of the volume wave signal curve, and taking the inflection point value of the volume wave signal curve as 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 an inflection point value of the volume wave signal curve, so how to acquire the inflection point value of the volume wave signal curve, the slope of the volume wave signal curve is mainly identified through the blood pressure measuring device, a volume wave signal point on the volume wave signal curve, the slope of which is changed from zero to non-zero, is identified, the volume wave signal point, the slope of which is changed from zero to non-zero, is the inflection point value of the volume wave signal curve, and the inflection point value of the volume wave signal curve is taken as the inflection point data; and acquiring a zero value of the volume wave signal curve, wherein how to acquire the zero value of the volume wave signal curve is mainly to acquire a volume wave signal point with a zero value on the volume wave signal curve, wherein the volume wave signal point with the zero value is the zero value of the volume wave signal curve, and then the zero value of the volume wave signal curve is used as the zero data. As shown in fig. 3, the volume wave signal of the second human body part changes when the pressurizing pressure applied to the first human body part gradually increases, and it can be seen that the volume wave signal of the second human body part starts to change, i.e., starts to decrease, when the pressurizing pressure increases from zero to a certain pressure, and the volume wave signal of the second human body part continuously decreases when the pressurizing pressure continues to increase, and the volume wave signal of the second human body part decreases to zero when the pressurizing pressure increases to another pressure.
In one embodiment, determining the blood pressure of the user from the inflection point data and the zero point data comprises:
acquiring the pressurization pressure corresponding to the inflection point value of the volume wave signal curve to obtain the diastolic pressure of the blood pressure;
acquiring the pressurizing pressure corresponding to the zero 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 pressure of the blood pressure and the systolic pressure of the blood pressure.
Specifically, after acquiring the inflection point value of the volume wave signal curve and the zero point value of the volume wave signal curve, the blood pressure measurement device acquires the pressurization pressure corresponding to the inflection point value of the volume wave signal curve, where the pressurization pressure corresponding to the inflection point value of the volume wave signal curve is the diastolic pressure of the blood pressure, and acquires the pressurization pressure corresponding to the zero point value of the volume wave signal curve, where the pressurization pressure corresponding to the zero point value of the volume wave signal curve is the systolic pressure of the blood pressure, and the diastolic pressure of the blood pressure and the systolic pressure of the blood pressure are the blood pressure of the user.

acquiring an inflection point value of the pulse wave signal curve, and taking the inflection point value of the pulse wave signal curve as inflection point data;
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.
In particular, instead of determining the blood pressure of the user by means of the volume wave signal, the blood pressure of the user may also be determined by means of the pulse wave signal. The blood pressure measuring device acquires the inflection point value of the pulse wave signal curve, so how to acquire the inflection point value of the pulse wave signal curve, the slope of the pulse wave signal curve is mainly identified through the blood pressure measuring device, then a pulse wave signal point on the pulse wave signal curve, the slope of which changes from zero to non-zero, is identified, the pulse wave signal point, the slope of which changes from zero to non-zero, is 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 acquiring a zero value of the pulse wave signal curve, wherein how to acquire the zero value of the pulse wave signal curve is mainly to acquire a pulse wave signal point with a zero value on the pulse wave signal curve, wherein the pulse wave signal point with the zero value is the zero value of the pulse wave signal curve, and then the zero value of the pulse wave signal curve is used as the zero data. As shown in fig. 3, the pulse wave signal of the second human body part changes when the pressurizing pressure applied to the first human body part gradually increases, and it can be seen that the pulse wave signal of the second human body part starts to change, i.e. starts to decrease, when the pressurizing pressure increases from zero to a certain pressure, and the pulse wave signal of the second human body part continuously decreases when the pressurizing pressure continues to increase, and the pulse wave signal of the second human body part decreases to zero when the pressurizing pressure increases to another pressure.
In one embodiment, determining the blood pressure of the user from the inflection point data and the zero point data comprises:
acquiring the pressurizing pressure corresponding to the inflection point value of the pulse wave signal curve to obtain the diastolic pressure of the blood pressure;
acquiring the pressurizing pressure corresponding to the zero value of the pulse wave signal curve to obtain the systolic pressure of the blood pressure;
and determining the blood pressure of the user according to the diastolic pressure of the blood pressure and the systolic pressure of the blood pressure.
Specifically, after acquiring 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 acquires the pressurization pressure corresponding to the inflection point value of the pulse wave signal curve, where the pressurization pressure corresponding to the inflection point value of the pulse wave signal curve is the diastolic pressure of the blood pressure, and acquires the pressurization pressure corresponding to the zero point value of the pulse wave signal curve, where the pressurization pressure corresponding to the zero point value of the pulse wave signal curve is the systolic pressure of the blood pressure, and the diastolic pressure of the blood pressure and the systolic pressure of the blood pressure are the blood pressure of the user.
In an embodiment, the acquiring inflection point data and zero point data of the change curve includes:
acquiring an inflection point value of the volume wave signal curve and an 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 inflection point data;
and acquiring a zero value of the volume wave signal curve and a 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.

and determining the blood pressure of the user according to the diastolic pressure of the blood pressure and the systolic 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 is to obtain the pressurizing pressure corresponding to the inflection point value of the volume wave signal curve and the pressurizing pressure corresponding to the inflection point value of the pulse wave signal curve mainly through a blood pressure measuring device, and then to perform weighted summation on the pressurizing pressure corresponding to the inflection point value of the volume wave signal curve and the pressurizing pressure corresponding to the inflection point value of the pulse wave signal curve to obtain the diastolic pressure of the blood pressure; meanwhile, the pressurization pressure corresponding to the zero value of the volume wave signal curve and the pressurization pressure corresponding to the zero value of the pulse wave signal curve are obtained, then the pressurization pressure corresponding to the zero value of the volume wave signal curve and the pressurization pressure corresponding to the zero value of the pulse wave signal curve are subjected to weighted summation to obtain the systolic pressure of the blood pressure, and the diastolic pressure of the blood pressure and the systolic pressure of the blood pressure are the blood pressure of the user. Therefore, the blood pressure is measured by matching the index of the volume wave signal and 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.
