Description

Watch wristband

The present application claims priority to Chinese Patent Application No. 200910931259.1, filed on Jan. in.

Technical field

The present application relates to the field of measurement technology, and in particular, to a wristband for measuring blood pressure.

Background technique

With the emergence of population aging, sub-health, environmental pollution and other issues, people's health requirements and attention are getting higher and higher. The emergence and rapid development of the Internet, smart terminals, wearable devices, and medical informatization have made mobile health an important process and a starting point for comprehensive assessment of user health. Among them, the data collection method of the user's physiological signal is an important step.

Taking blood pressure data as an example, the current methods of measuring blood pressure are mainly classified into two categories: the first type is the direct measurement method, which requires invading the body of the measurer, and will leave a certain wound to the user's body after the measurement. This method is mainly used in medical applications and requires very high accuracy. The second type is indirect measurement, which uses blood pressure measuring instruments to collect blood pressure data in two ways. One of them is a cuff method, which includes: auscultation, oscillometry, and volumetric clamping; one is a cuffless manner, which includes: tension measurement, pulse wave velocity, and photoplethysmography. (photoplethysmograhy, PPG) or imaging photoplethysmograhy (IPPG). If the user collects blood pressure data using the first type of measurement method, although the accuracy of the collected blood pressure data is high, the method can generally only be operated by a professional in a specific place such as a hospital, and cannot be measured at any time in daily life. If the user uses the second type of measurement method to collect blood pressure data, the method of collecting the method is too simple (such as a cuffless manner) and the collected signal is generally weak and the accuracy is not high.

In addition, some wearable devices also use pulse wave velocity method (such as cuff), tension measurement method, and oscillometric method to collect blood pressure data. However, when the blood pressure data is collected by the pulse wave velocity method, the user needs to calibrate the wearable device frequently, and the accuracy is not high; when the blood pressure data is collected by the tension measurement method, the user needs to press the radial artery, which is difficult to control, so the measurement is performed. The accuracy is not high.

Summary of the invention

The embodiment of the present application provides a wristwatch wristband for accurately and reasonably collecting blood pressure data in a daily life. The wristband of the wristwatch can ensure the accuracy of collecting blood pressure data and continuously measure blood pressure data. In addition, when the blood pressure is measured by the oscillometric method using the wristband of the wristwatch of the present application, the volume of the airbag is designed to be equivalent to the size of the wristband of the wristwatch while accurately and reasonably measuring, and the appearance is improved while improving the user experience. sense.

The wristband of the watch transmits the first blood pressure value to the terminal to facilitate display by the terminal;

The terminal stores the first blood pressure value, and records the first blood pressure value as a calibration parameter; when the calibration parameter is within a preset effective period, the terminal further measures a physiological parameter by using a non-oscillometric method, The second blood pressure value is determined according to the physiological parameter measured by the non-oscillometric method, and the terminal corrects the second blood pressure value according to the calibration parameter.
