Huawei has so many patents on its portfolio and joining with this current month, the company has now published a new patent for “ECG detection equipment and detection circuit” with the publication number is CN113796872A.
According to the patent details, this application provides electrocardiogram detection equipment and detection circuit, which belong to the field of electronic technology.
The casing of the electrocardiogram detection device may be made of conductive material, and the electrocardiogram detection device may include a voltage holding circuit for providing the casing with a target potential. The description also shows that the potential difference between the target potential provided by the voltage holding circuit and the reference potential provided by the electrocardiogram detection circuit for the third electrode is small, even during the ECG detection process, the user accidentally touches the case, causing the case to interact with the third electrode. If the electrode is turned on, there is no leakage current between the casing and the third electrode, or the leakage current generated is small.
This Huawei patent can effectively reduce the interference to ECG signals and ensure the accuracy of ECG detection, As we know that the company is set to launch its new products on December 23, 2021, and in the same event Huawei will launch a new ECG blood pressure recorder HUAWEI WATCH D smartwatch. The device has been registered as a Class II medical device by the China Food Administration.
