We have heard various rumors about the possibility that a future Apple Watch to be able to measure blood pressure. To perform this measurement, very specific sensors are necessary, those which could be located on the strap of the same watch, according to a recent patent.
Another approach to measuring pressure
While we have already seen the likelihood of taking a blood pressure measurement using only light sensors there are other approaches that also make sense. One of them is to add a sensor to the upper arm. A device connected to Apple Watch with which to measure.
Another alternative is to offer a sensor that is worn permanently. This is exactly what the Stretchable Blood Pressure Cuff patent does, which explores the possibility of something similar to a bracelet for the Apple Watch which the interior is able to perform a pressure measurement
“A user can monitor one or more of their physiological parameters by connecting a monitoring device, such as a blood pressure monitor, to one of their limbs. The blood pressure monitor can include an inextensible section that secures an inflatable section against the patient’s limb. . Username”.
“This would compress one or more blood vessels in the limb, restricting and / or stopping blood flow through the vessels.”
Several approaches for the same reading.
This information could “be used to determine one or more physiological parameters, such as the user’s blood pressure.” It is clear that it is not intended to wear a device that regularly inflates on the wrist or arm. On the other hand, anyone who really needs to take these measurements continuously, can greatly benefit from something similar to a special bracelet for the Apple Watch with which the need for additional devices is eliminated
“A physiological monitor such as the blood pressure cuff is usually worn during measurement and is removed promptly afterwards. In some cases, it may be desirable to wear the monitor for longer periods of time, so that patients are physiological measurements can be performed periodically or continuously. “
The cuff assembly may include a fluid conduit which is in communication with the first cell and the second cell and in conjunction with a reservoir. The cuff assembly may exchange liquid with the reservoir and be configured to increase in length as time goes. that the volume of liquid in the internal chamber decreases, and decreases in length as the volume of the fluid in the internal chamber increases ”.
A description that may seem trivial, but which, given the image accompanying the text, quickly may remind us of the leather strap that Apple already sells currently for the Apple Watch.
Obviously, there are different methods to get an effective blood pressure reading. While Apple is expected to focus its efforts on a non-invasive device, surely using light sensors, it is also possible that a more classic approach could be taken. We will be attentive to rumors related to this interesting patent.
