Intelligent bracelet for measuring blood pressure and heart rate

Abstract

The invention relates to an intelligent wearable terminal, in particular to an intelligent bracelet for measuring the blood pressure and the heart rate. The intelligent bracelet includes at least two bracelet bodies, a blood pressure acquisition device and a heart rate acquisition device; the blood pressure acquisition device includes that a closed ring is formed by connecting the bracelet bodies through a buckle, grooves are formed in the inner sides of the bracelet bodies, the grooves form a closed circumference in the extending directions of the bracelet bodies, air bags matched with the grooves in shape is arranged are the grooves, and the air bags are connected with an air pump and a pressure sensor; the heart rate acquisition device includes a photosensitive chip and a vibration sensor; both the blood pressure acquisition device and the heart rate acquisition device are connected with a control system installed in the ring, the heart rate acquisition device is used for acquiring heart rate information of a user and uploading the heart rate information to a central processor, and the blood pressure acquisition device is used for acquiring blood pressure information of the user and uploading the blood pressure information to the central processor.

Description

technical field [0001] The invention relates to an intelligent wearing terminal, in particular to an intelligent bracelet for measuring blood pressure and heart rate. Background technique [0002] A smart bracelet is a wearable smart device. Through smart bracelets, users can record real-time data such as exercise, sleep, and some diets in daily life, and synchronize these data with electronic devices such as mobile phones and tablets to play a role in guiding healthy life through data. [0003] Heart rate is the most direct indicator of our health. The healthy heart of a normal person will beat according to its established rules all the time, pumping blood to every place in the body. The heart is the driving force for blood pumping, and it is also the guarantee for the normal operation of various organ systems and the whole body. Professional continuous heart rate monitoring, the medically approved method is 24-hour dynamic heart rate monitoring in the hospital. This te...

Problems solved by technology

However, these wristbands have the following problems in measuring heart rate: Most of the wristbands monitor the heart rate once a minute, but in fact our heart beats about 60 to 100 times per minute, and within one minute, our heart rate is often already Experienced rapid changes, but the wristband can not detect these changes

However, if there is a violent movement of the measured part, it will affect the extraction of regular pulsation signals, and the measurement cannot be carried out. When the patient's peripheral circulation is severely impeded, the arterial blood flow of the measured part will decrease, which will make the measurement inaccurate. Or it cannot be measured; in patients with severe blood loss, when the body temperature of the measurement site is low, the external strong light may irradiate the probe, which may cause the work of the photoelectric receiver to deviate from the normal range, resulting in inaccurate measurement

Therefore, the use of photoelectric detectors to monitor blood pressure will have the following problems (1) the error in measuring the blood pressure of the human body through the photoelectric sensor chip of the wristband is large; (2) due to the sudden onset of hypertension and other diseases, it is necessary to Real-time monitoring, but existing products cannot realize systematic management of users; (3) Due to the many programs running inside the bracelet, the battery life is relatively short and charging is frequent
