Apple has been actively improving health and fitness-related features for its devices, especially the wearable ones. In line with that, the tech giant has been granted a new patent related to a major blood pressure monitoring system.
Now, a new patent application from Apple, published by the US Patent & Trademark Office reveals a major shift in the company’s blood pressure system. It includes an all-new wearable device, which is separate from Apple Watch.
It seems that instead of a watch interface, the cuff comes with a control unit and the company confirms that the control unit can offer a user interface, including Watch-related functionalities. The product is aimed at estimating the blood pressure value of a patient.
The method covered in this patent includes receiving feature vector data corresponding to a pressure variation of the blood pressure cuff. The data is derived from one or more physiological signals of the patient measured over the pressure variation of the blood pressure cuff.

A first blood pressure value is estimated using the first algorithm with feature vector data as input data. It is then configured to be an estimate of one of the systolic blood pressure of the patient, the diastolic blood pressure of the patient, and the mean arterial blood pressure of the patient.
It is noted that the algorithm is configured to estimate the first blood pressure value of the patient to account for differences between changes in the shape, and/or timing of the one or more physiological signals of the patient measured over the pressure variation of the blood pressure cuff.
