Problems solved by technology

[0004] However, since the size of wearable devices is generally relatively compact, the distance between the ports of each airflow channel is small. During the measurement process, the fluid pump may generate airflow impact when supplying air to the airbag, which will interfere with the measurement of the sensor and affect measurement accuracy

Embodiment Construction

[0055] Before describing the embodiment of the present application, in order to facilitate the understanding of the technical solution of the present application, the basic concepts and terms involved in the embodiment of the present application are firstly explained:

[0056] Blood pressure (BP) refers to the lateral pressure acting on the side wall of the blood vessel per unit area when the blood pressure flows inside the blood vessel. Blood pressure is the main driver of blood flow. The blood pressure of the human body needs to be kept within the normal fluctuation range, too high or too low will have adverse effects on human health. Because of the difference in blood vessels, blood pressure is called arterial blood pressure, venous blood pressure, and capillary blood pressure. The blood pressure measured in general anthropometrics is arterial blood pressure.

[0057] Oscillometric blood pressure measurement: through the vibration caused by the collision of the blood vess...

Abstract

The invention provides electronic equipment for measuring blood pressure. The electronic equipment for measuring the blood pressure comprises a measuring assembly, an air bag and a fluid pipeline. A fluid pump and a pressure sensor in the measuring assembly correspondingly communicate with the air bag through a first fluid pipeline and a second fluid pipeline, a first pipe opening of the first fluid pipeline and a second pipe opening of the second fluid pipeline are formed in the same side of the air bag, and the opening direction of one of the first pipe opening and the second pipe opening deviates from the other one, so that the first pipe opening and the second pipe opening are far away from each other. Therefore, interference of air flow of the air bag on the pressure sensor is reduced, and blood pressure measuring precision is improved.

Description

technical field [0001] The present application relates to the field of electronic equipment, in particular to an electronic equipment for measuring blood pressure. Background technique [0002] With the improvement of modern people's attention to health, more and more wearable devices or other electronic devices have integrated blood pressure measurement function to monitor the human body's blood pressure and other physiological indicators anytime and anywhere. [0003] At present, devices with a blood pressure measurement function generally perform measurement by an oscillometric method. Specifically, the oscillometric method uses the balloon to compress the subject's artery, and the blood pressure in the subject's artery will impact the balloon, causing pressure fluctuations in the air pressure inside the balloon. After obtaining the fluctuation of the air pressure inside the balloon, you can calculate Obtain the subject's blood pressure and other indicators. For example...
