Technical Field

[0001] The present invention relates to the technical field of blood pressure monitoring, and in particular to a method and device for managing optical non-contact automatic dynamic blood pressure monitoring. Background Art

[0002] Currently, blood pressure measurement is done through the oscillometric method. Although its accuracy is recognized by medicine, it has inherent shortcomings because it requires the person being measured to be in a static state and the measuring part must be flush with the heart to ensure the measurement accuracy. However, for the vast majority of users, especially those with hypertension, they lack a product that can dynamically monitor blood pressure during their daily exercise life, so as to monitor blood pressure changes in real time and manage blood pressure in a timely manner.

[0003] In view of this, it is necessary to provide an optical non-contact automatic dynamic blood pressure monitoring management method and device to overcome the above-mentioned defects. Summary of the invention

[0004] The purpose of the present invention is to provide an optical non-contact automatic dynamic blood pressure monitoring management method and device, aiming to solve the current problem of being unable to monitor blood pressure changes in real time.

[0005] In order to achieve the above-mentioned object, the first aspect of the present invention provides an optical non-contact automatic dynamic blood pressure monitoring management method, comprising:

[0006] Obtaining the pre-stored resting blood pressure reference value and static heart rate reference value of the user using the medical device in a resting state; wherein the resting blood pressure reference value includes a resting diastolic pressure reference value and a resting systolic pressure reference value;

[0007] Get the user's exercise heart rate value monitored by the wearable device;

[0008] The user's current dynamic blood pressure is calculated and evaluated according to the exercise heart rate value and the preset dynamic blood pressure formula; wherein the dynamic blood pressure formula is as follows:

[0009] In the formula, dp is diastolic pressure, sp is systolic pressure, E BP is the dynamic blood pressure ratio, E dp is the dynamic diastolic pressure value, E sp is the dynamic systolic blood pressure value, V dp is the resting diastolic blood pressure baseline, V sp is the baseline value of resting systolic blood pressure, E HR is the exercise heart rate, V RHR This is the resting heart rate baseline.

[0010] In a preferred embodiment, when the number of static heart rate collections does not exceed the preset number, the static heart rate reference value adopts the heart rate value collected this time; when the number of static heart rate collections exceeds the preset number, the static heart rate reference value adopts the average heart rate value obtained by multiple static collections.

[0011] In a preferred embodiment, when a wearable device or App is connected to a medical-grade blood pressure monitor for blood pressure measurement, a window pops up and obtains the user's identity selection result for the current measuring person, and after the measurement is completed, the resting blood pressure baseline value of the current measuring person is updated accordingly in the wearable device or APP.

[0012] The second aspect of the present invention provides an optical non-contact automatic dynamic blood pressure monitoring and management device, comprising:

[0013] A reference value acquisition module, used to acquire a pre-stored resting blood pressure reference value and a static heart rate reference value of a user using a medical device in a resting state; wherein the resting blood pressure reference value includes a resting diastolic pressure reference value and a resting systolic pressure reference value;

[0014] The dynamic heart rate acquisition module is used to obtain the user's exercise heart rate value monitored by the wearable device;

[0015] The dynamic blood pressure acquisition module is used to calculate and evaluate the user's current dynamic blood pressure based on the exercise heart rate value and a preset dynamic blood pressure formula; wherein the dynamic blood pressure formula is as follows:

[0017] A third aspect of the present invention provides a terminal, which includes a memory, a processor, and a computer program stored in the memory. When the computer program is executed by the processor, it implements the various steps of the optical non-contact automatic dynamic blood pressure monitoring management method as described in any one of the above embodiments.

[0020] The optical non-contact automatic dynamic blood pressure monitoring management method and device provided by the present invention is based on the close relationship between heart rate and blood pressure: on the one hand, an increase in heart rate will lead to an increase in blood pressure, because a faster heartbeat will increase the blood flow rate in the blood vessels, thereby increasing blood pressure; on the other hand, an increase in blood pressure will also stimulate the heart to beat faster to ensure that enough blood flows to all parts of the body; therefore, based on the statically collected blood pressure value and static heart rate value, the real-time dynamic blood pressure value is calculated in combination with the dynamic blood pressure formula. Among them, the dynamic heart rate can be monitored in real time through a wearable device, and there is no need to align the measuring part with the heart. Therefore, when the user's static blood pressure value is accurately collected, the relative accuracy of the dynamic blood pressure value has a certain reference significance.

[0027] Embodiment 1

[0028] In an embodiment of the present invention, an optical non-contact automatic dynamic blood pressure monitoring and management method is provided, which utilizes the close relationship between heart rate indicators and blood pressure, and combines the dynamic blood pressure estimation algorithm to calculate the real-time dynamic blood pressure value based on the blood pressure value and static heart rate value collected by the user using medical equipment in a static state, so that the user can use it as a reference.

[0029] like Figure 1 As shown, the optical non-contact automatic dynamic blood pressure monitoring management method includes steps S10-S30.

[0030] Step S10: Obtaining the pre-stored resting blood pressure reference value and static heart rate reference value of the user using the medical device in a resting state; wherein the resting blood pressure reference value includes a resting diastolic pressure reference value and a resting systolic pressure reference value.

[0031] Furthermore, when a wearable device or App is connected to a medical-grade blood pressure monitor for blood pressure measurement, a pop-up window will be displayed to obtain the user's identity selection result for the current measuring person, and after the measurement is completed, the resting blood pressure baseline value of the current measuring person will be updated accordingly in the wearable device or App.

[0032] Among them, when the user registers on the APP and operates wearable devices such as smart watches for the first time, he will enter the standard blood pressure value measured in a standard posture by a medical-grade blood pressure monitor.

[0033] Further, when the number of static heart rate collections does not exceed the preset number, the static heart rate reference value adopts the heart rate value collected statically this time. When the number of static heart rate collections exceeds the preset number (for example, three times), the static heart rate reference value adopts the average heart rate value obtained by multiple static collections.

[0034] Step S20: Obtain the exercise heart rate value monitored by the user through the wearable device.

[0035] It should be noted that the principle of how wearable devices such as smart watches obtain the wearer's heart rate can refer to the existing technology, and the present invention will not be repeated here.

[0036] Step S30: Calculate and evaluate the user's current dynamic blood pressure according to the exercise heart rate value and a preset dynamic blood pressure formula; wherein the dynamic blood pressure formula is as follows:

[0037] In the formula, dp is diastolic pressure, sp is systolic pressure, E BPis the dynamic blood pressure ratio, E dp is the dynamic diastolic pressure value, E sp is the dynamic systolic blood pressure value, V dp is the resting diastolic blood pressure baseline, V sp is the baseline value of resting systolic blood pressure, E HR is the exercise heart rate, V RHR This is the resting heart rate baseline.

[0038] It should be noted that research has found that: based on the heart rate baseline, for every 1 BPM increase in real-time heart rate, the blood pressure value at the corresponding time increases as follows: systolic pressure increases by 0.4 mmHg, and diastolic pressure increases by 0.7 mmHg.
