One step closer to the Apple Watch with a blood pressure sensor shows a patent that would include a sensing chamber with liquid inside
According to Patently Apple, those from Cupertino have published a request for patent related to Apple Watch and the measurement of blood pressure. What is curious is that now the use of a device which uses “a liquid-filled detection chamber”. It is recognized that the measurement is “difficult to determine precisely” but With this new patent, you would be closer to having a more reliable measurement. We have already told you about the delay in the inclusion of new sensors in the Apple Watch.
Apple pulls out all the stops with a new patent to measure blood pressure with the Apple Watch
If you think Apple will want to take some of your blood to measure your blood pressure, you're wrong. Liquid detection chamber will be filled with a fixed amount and will be sealed in such a way that it does not vary to make a correct measurement. It will be part of a compression system which will in turn be separated from said camera but which I'm going to put pressure on him.
This also raises the placement of a vibrating sensor inside the chamber which will be used to measure these vibrations “from the user and towards the liquid present in the chamber”. The vibrating sensor It will work as a blood flow detectorsomething familiar with what happens with Korotkov measurements (the sound of atrial contraction, known as atrial systole in blood pressure measurement).
The compression system could be inflated in such a way that the system will determine compliance with a criterionin the event that a “maximum sound intensity in the blood flow” or any sound that can determine the user's hypertension and hypotension is reached.
Patent for an Apple Watch with liquid blood pressure sensor and vibration
Why is it essential to have cash in the Apple Watch?
According to Patently Apple, the liquid detection chamber “may be more sensitive to pressure changes in the blood vessel compared to conventional air detection chambers” due to a natural “incompressible” problem of the liquid.
Even the traditional extent to which rubber is used with air could be improved. where a person's arm is compressed. On the Apple Watch, the wristband would attach the sensing camera against the wearer's skin and the measuring device would be independent, meaning it could be “mounted or integrated” into the wristband.
Traditional blood pressure measurement
Initially, it could be integrated into the Apple Watch, but If necessary, it could be integrated with other devices or in places other than the wrist. to measure blood pressure. Apple's patent was filed by an Apple engineer named Caleb Han, an experienced man who has been with the company for 11 years.
In the figures presented in the patent it can be seen that the chamber is not too large, therefore Apple would bet on integrating everything into its smart watch. We hope to have future reports indicating that those in Cupertino have already managed to have a working prototype. Did you know that the first Apple Watch would have advanced health features?
