Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of sphygmomanometer, in particular to a sphygmomanometer capable of automatically adjusting the contraction strength. BACKGROUND

[0002] With the improvement of people's living standards and the increasing of people's health care concept, the demand for medical health electronic products is also increasing year by year. Among them, sphygmomanometer is one of the most widely used markets in medical equipment. People generally pay more attention to daily monitoring of their own blood pressure. Wrist sphygmomanometer, as a kind of medical equipment worn on the wrist, not only measures and monitors human parameters, but also realizes people's dependence on wearable devices, and monitors the health of the human body at all times. Wrist sphygmomanometer usually uses oscillometric method to measure blood pressure by establishing the relationship between systolic pressure, diastolic pressure, mean pressure and cuff pressure oscillation wave. When using, the cuff is first buckled on the wrist, and after starting, the cuff is automatically inflated and pressurized, and then deflated and released. During the inflation and deflation process, the systolic pressure and diastolic pressure are automatically detected and recorded, and the display value is fed back to the measurer to reflect the physical health status.

[0003] However, most of the wrist sphygmomanometers now are two-segment structures, which are buckled on the wrist and then fixed by magic tape. After long-term use, the adhesive surface is easy to wear and tear, resulting in poor adhesion. When measuring blood pressure, it needs to be fixed by hand to perform normal measurement. Even in the process of blood pressure measurement, the wrist band self-adhesive surface may be disconnected due to poor adhesion, thereby affecting the stability and accuracy of blood pressure detection. In the process of blood pressure detection, the wrist band is manually bound by the doctor, and sometimes the force cannot be controlled, which may cause injury due to tight binding of the arm.
