Description

Technical Field

[0001] This application relates to the technical field of cardiovascular monitoring, and particularly to a multifunctional cardiovascular monitoring system. Background Art

[0002] Cardiovascular diseases cause more than 17 million deaths every year, accounting for 31% of the global death toll. By 2030, this figure is expected to increase to 23.6 million. Cardiovascular diseases are the leading cause of death globally, but wearable monitoring technologies can change the way these diseases are diagnosed and managed. In particular, continuous monitoring of cardiovascular vital signs is highly desirable for early intervention. For this purpose, flexible wearable sensors that can be comfortably worn for long periods are attracting great attention.

[0003] Among them, a cardiovascular monitoring system prevents cardiovascular diseases through early monitoring. For example, a multifunctional cardiovascular monitoring system with the publication number CN109350026A includes an activity ring. Connecting rods are arranged on the left and right sides of the activity ring. The connecting rods are made of rubber band material. One side of the activity ring is connected with a connecting ring, and one side of the connecting ring is connected with a first fixing member, and one side of the first fixing member is connected with a second fixing member. On both sides of the blood pressure detection display screen on the portable hand ring for detecting blood vessel diseases of this multifunctional cardiovascular monitoring system, activity rings are connected through connecting members. The activity rings can perform telescopic movements. Two connecting rods are inserted inside the activity rings. The connecting rods are set to be made of rubber band material. In this way, the diameter of the detection cardiovascular hand ring can be adjusted through the connecting rods and the activity rings, so that the size of the detection hand ring can be adjusted according to the situation. In this way, it is also more convenient to wear, suitable for a person to carry around, and the activity ring and the blood pressure detection display screen can be disassembled, making use and storage more convenient.

[0004] However, the above-mentioned prior art still has some defects when performing cardiovascular monitoring: 1. The above-mentioned prior art adjusts the diameter of the monitoring cardiovascular hand ring through the connecting rods and the activity rings, so that the size of the monitoring hand ring can be adjusted according to the situation. However, the data obtained only through the hand ring monitoring is limited and inaccurate, and cannot well reflect the cardiovascular state of the patient at this time.

[0005] 2. The above-mentioned prior art is worn on the arm, which is more convenient to wear, suitable for a person to carry around, and the activity ring and the blood pressure detection display screen can be disassembled, making use and storage more convenient.
