Background
Non-invasive blood pressure measurement, one of the most frequently used monitoring means in the medical industry, has been plagued by the problem that accurate detection or continuous detection is impossible. The most common non-invasive blood pressure measurement is the cuff method, but the method needs to inflate and deflate the cuff to measure the blood pressure, continuous measurement cannot be achieved, and short-term blood pressure changes are very important in many scenes. Therefore, a method for continuously and accurately detecting blood pressure is required.
In the human anatomy, the radial artery originates from the brachial artery bifurcation of the antecubital fossa, which extends distally at the anterior end of the forearm and is the major artery outside the forearm. The clinician takes a radial pulse at the radial artery, typically to assess heart rate and blood pressure. In the last two decades, the radial pulse wave measurement has been developed rapidly, and the various information presented by the radial pulse wave reflects the blood flow characteristics of the human vascular system to a great extent.
The existing radial artery pulse wave detection system needs to accurately locate the position of the radial artery by a nursing staff in advance. Once the position is not accurate enough or the system is out of position due to the movement of the body, the measurement results become very inaccurate. For this reason, it is necessary to design a device capable of automatically locating the radial artery position.
