Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a portable sphygmomanometer. Background Art

[0002] Blood pressure is the pressure exerted on the blood vessel walls when blood flows in the human body. This pressure is generally within a certain range. If it is higher or lower than a certain value, it will affect human health. A sphygmomanometer can measure human blood pressure and detect human health. With the development of society, sphygmomanometers are becoming more and more intelligent and convenient, and are gradually entering ordinary households.

[0003] When using the blood pressure monitor, the main body needs to be placed on the user's wrist, and then the straps on both sides of the main body need to be controlled to move closer to each other and buckle together.
