As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

Referring to fig. 1, the monitoring device 100 includes a first electronic wristband 10 and a second electronic wristband 20, the first electronic wristband 10 may be used to be worn on a wrist of a target subject, and the second electronic wristband 20 may be used to be worn on another wrist of the target subject, for example, a cunkou pulse position as shown in fig. 2, so that the first electronic wristband 10 and the second electronic wristband 20 are both closer to a pulse, and thus, pulse beating conditions can be better collected to measure a first pulse intensity and a second pulse intensity, respectively.

The first electronic wristband 10 includes a first wristband body 110, a first pulse sensor 101, a first communication module 102, and a first controller 103. The first pulse sensor 101, the first communication module 102 and the first controller 103 are disposed on the first wrist band body 110. For example, the first wrist strap body 110 may be an integrally formed silicone strap, and the silicone strap is provided with a receiving slot capable of receiving the first pulse sensor 101, the first communication module 102 and the first controller 103, so that the first pulse sensor 101, the first communication module 102 and the first controller 103 are all disposed in the receiving slot of the silicone strap. The first controller 103 is connected to the first pulse sensor 101 and the first communication module 102, respectively, for example, as illustrated by a bus connection in fig. 3 (a).

The second controller 203 is connected to the second pulse sensor 201 and the second communication module 202, respectively, for example, a bus connection is exemplified in fig. 3 (b).

It is to be understood that the target object may be a user using the first and second electronic bracelets 10 and 20, such as an elderly person or a middle aged person. The first pulse sensor 101 in the first electronic wristband 10 is used for detecting the pulse beat condition of the wrist to determine a first pulse intensity, and the second pulse sensor 201 in the second electronic wristband 20 is used for detecting the pulse beat condition of the other wrist to determine a second pulse intensity.

It is understood that the pulse beat is caused by the sound that appears after each contraction of the heart pumping blood to the blood vessels. In addition, when the target object suffers from angiosclerosis, the blood pressure of the two upper limbs of the target object has large difference, so that the pulse intensity at the cun-oral pulse of the two wrists has large difference. Thus, the pulse beat condition can reflect the heartbeat condition on one hand and the hardening condition of the blood vessel on the other hand.

Therefore, the first electronic wrist strap 10 is worn at one wrist of a target object, so that the pulse beating condition at the cun-kou pulse of the target object can be detected, and the first pulse intensity of the target object can be acquired; when the second electronic wrist strap 20 is worn on the other wrist of the target subject, the pulse beating condition at the other cun-vena cava of the target subject can be detected, and the second pulse intensity of the target subject can be obtained.

Based on the communication connection between the first communication module 102 and the second communication module 202, the second controller 203 may control the second communication module 202 to transmit the second pulse intensity to the first electronic wristband 10, so that the first controller 103 may determine whether the target object has vascular sclerosis according to the difference between the first pulse intensity and the second pulse intensity. For example, when the difference value is greater than or equal to a preset difference threshold value, it is determined that the target object has vascular sclerosis, and when the difference value is less than the preset difference threshold value, it is determined that the target object has not vascular sclerosis. It is understood that the preset difference threshold may be an empirical value or may be determined by one skilled in the art according to experimental results.

In order to make the first wristband body 110 and the second wristband body 210 fit the pulse position of the wrist more closely, so as to facilitate the first pulse sensor 101 and the second pulse sensor 201 to collect pulse beating more accurately, in some embodiments, please refer to fig. 4, the first wristband body 110 includes a first elastic band 108 and a first housing 109, the first housing 109 is disposed on the first elastic band 108, the first housing 109 is provided with a first accommodating cavity, and the first pulse sensor 101, the first communication module 102 and the first controller 103 are all accommodated in the first accommodating cavity, so as to be protected by the first housing 109.
