According to Patently Apple, Cupertinos have issued a request. Patent related to Apple Watch and measurement blood pressure. The interesting thing is that now the use of a device uses a “liquid-filled sensing chamber”. The measurement is acknowledged to be “difficult to determine precisely” but With this new patent you will be closer to a more reliable measurement. We have previously told you about the delay in adding new sensors to Apple Watch.

Apple sets out with a new patent to measure blood pressure with Apple Watch

If you think Apple would want to take some of your blood to measure your blood pressure, you’re wrong. liquid detection chamber To be filled and sealed with a fixed amount In order to make an accurate measurement, it will not change. Will be part of the compression system This will also be separated from the camera in question, but which will put pressure on him.

It also raises placing the vibration sensor inside the chamber This will serve to measure vibrations “from the user and towards the liquid in the chamber.” vibrating sensor Will work as a blood flow detectorSomething similar to what happens with Korotkov measurements (the sound of atrial contraction, known as atrial systole in blood pressure measurement).

The compression system can be inflated by: the system will determine compliance with a criterionIn case of reaching “maximum sound intensity in blood flow” or any sound that can determine the user’s high and low blood pressure.

Patent for Apple Watch with fluid tension sensor and vibration

Why is it important to have liquid on Apple Watch?

Liquid sensing chamber according to Patently AppleMay be more sensitive to pressure changes in the blood vessel compared to conventional airborne sensing chambers due to the inherent “incompressible” outflow of fluid.

Even traditional measurement using rubber with air can be improved Where a person’s arm is pinned. On the Apple Watch, the band will secure the detection camera to the user’s skin, and the measurement device will be self-contained, meaning it can be “mounted or integrated” into the band.

Conventional blood pressure measurement

It could initially be integrated into the Apple Watch, but When necessary, it can be integrated with other devices or places other than the wrist. To measure blood pressure. Apple’s patent was made by an experienced Apple engineer named Caleb Han, who has been working at the company for 11 years.

In the figures presented in the patent, it can be seen that the chamber is not very large, so Apple is ambitious about integrating everything into its smart watch. We hope to receive reports in the future showing that the Cupertinos have managed to have a functional prototype. Did you know that the first Apple Watch will have advanced health features?
