Oppo is given a patent that can change the way to apply a blood pressure measurement system in smartwatch. The patent filed in the World Intellectual Property Organization (WIPO) explains how the company is planning to create existing airbag technology, which is also used by Huawei in Huawei Watch D2, which is used to measure blood pressure more efficiently. .
How do existing blood pressure monitoring systems work in smartwatch?
- So far, smartwatch uses an airbag in strap, which is inflated to measure blood pressure through an air pump that is located in the watch head. This air pump is attached to an air bag that is often set on a watch head and is inflated through air nozzle.
- It is somewhat similar to how Blood pressure monitoring mechanism In Huawei clock d2 Works Here’s video:
However, this system has a major defect. Additional space is required in the watch head to adjust the air nozzle. This, in turn, limits the location that can be potentially used by other components, including sensors, to provide new functionality.
How does Oppo patent change it?
- Oppo, in PatentProposes a separate mechanism that integrates the air tract by integrating it in the watch strap.
- When the head of the clock is attached to the clock strap, it creates an air tract, which in turn eliminates the need to have a separate air nozzle to inflate the airbag while taking blood pressure.
- The patent proposes that the watch head has a shell assembly, which has an air pump and air road. This air pump blooms and implicates the airbag through Air Path, which connects the air pump outside the watch head using an opening.
- Saying this simply, the strap helps to complete the air path, which has an air pump and opening at one end (towards the watch head) and strap and airbags at the other end. The watch head connects to the strap, which calls the patent ‘connecting assembly’.
- In addition, the patent states that the mentioned mechanism not only simplifies the manufacturing process, but it also makes it for better placement of internal components. Additionally, it leaves space for more creative designs.
This is worth noting, while Oppo is given a patent, when it decides to bring this technique into its smartwatch, it remains to be seen. Some reports suggest that the company will bring blood pressure monitor with its upcoming Oppo Watch X2. However, there is no word on whether it facilitates the same technique mentioned in the smartwatch patent.
