Huawei has recently announced that it can now produce medical equipment and the company has already got approval for a single-lead electrocardiogram (ECG) device to become its journey in this new field. Adding to this, He Gang, President of Huawei consumer business mobile product line previously confirmed to us that Huawei is also working on a new smartwatch with a blood pressure measurement feature.
Related to this, now we have some more information regarding this matter and how the blood pressure monitor of this watch would work.
According to a patent filed by Huawei, while measuring the blood pressure on the wrist, the wrist-type electronic sphygmomanometer measures the air pressure signal in the airbag through the air pressure sensor connected to the airbag.
In the case of the same wrist circumference, if the subject’s wrist fat is thicker and the radial artery is hidden deeper, the adipose tissue has a certain elasticity and acts as a buffer, which will cause the air pressure in the balloon to be greater than the real compression on the radial artery.
The pulse wave signal will shift to the right due to the pressure at the position, causing the measured blood pressure to be higher than the true systolic blood pressure.
According to the information, the Chinese tech maker has applied this patent with the name “Blood Pressure Detection Device” and has patent application number of 202020567693 on April 16, 2020, in China.
Below you can check all of the information regarding this patent (translated text from Chinese)
Patent description of Huawei Blood Pressure Smartwatch Feature:
Figure 1 is a block diagram of a module of the blood pressure detection device proposed by the present invention. The device includes a wrist circumference detection component 03, a wrist fat thickness detection component 01, a blood pressure detection component 02, and a processor 04. The processor and the other three Component connections.
The wrist circumference detection component obtains the user’s wrist circumference data, the wrist fat thickness detection component obtains the user’s wrist fat thickness data, and the blood pressure detection component obtains the user’s blood pressure data. Finally, the processor, based on the wrist circumference data and the wrist fat thickness data, The blood pressure data is corrected.
The processor specifically determines whether the blood pressure data needs to be corrected according to the wrist circumference data and the wrist fat thickness data, and when the blood pressure data needs to be corrected, obtains the corresponding wrist circumference data and wrist fat thickness data from the preset database.
The mapping relationship is used to correct the blood pressure data. The blood pressure detection device includes a main body and a watchband connected to the main body. The watchband wears the main body on the user’s wrist, and the main body also includes a processor.
The wrist circumference detection component includes adjustable components and an electrical parameter detection circuit. The two components are connected. The electrical parameter detection circuit is located inside the main body. Correspondence of the data to obtain the wrist circumference data corresponding to the detected electrical parameters.
The wrist fat thickness detection component includes an excitation electrode, a detection electrode and an impedance detection circuit. The excitation electrode is located on the side of the main body and can transmit the excitation voltage.
The detection electrode is arranged at the bottom of the main body to receive the detection voltage, which is generated by the excitation voltage according to the pressure drop of the user’s wrist fat.
The impedance detection circuit is arranged inside the main body and can generate an excitation voltage, and calculate and obtain wrist fat thickness data based on the excitation voltage and the detection voltage.
In short, Huawei’s blood pressure monitoring device patent improves the accuracy of blood pressure measurement by obtaining the user’s wrist circumference data and wrist fat thickness data, as well as the compatibility of the blood pressure measurement device, which enhances the user’s wearing experience.
