Definitions
- the present invention relates to a blood pressure measuring device, and more particularly, to a blood pressure measuring device capable of measuring blood pressure by being worn on a user's wrist.
- Blood pressure information is one of the important information in determining health conditions. Blood pressure is the pressure that blood exerts on the walls of blood vessels. When the heart contracts and pushes blood, the pressure in the blood vessels is called systolic or systolic pressure, and when the heart relaxes to receive blood, the pressure in the blood vessels is called diastolic or diastolic pressure.
- the blood pressure of a healthy person is less than 120 mmHg for systolic blood pressure and less than 80 mmHg for diastolic blood pressure.
- a person with a systolic blood pressure of 140 mmHg or more and a diastolic blood pressure of 90 mmHg or more has high blood pressure, and a person with a systolic blood pressure of 90 mmHg or less and a diastolic blood pressure of 60 mmHg or less has hypotension.
- Methods for measuring blood pressure generally include an auscultation method, an oscillometric method, a tonometric method, and the like.
- the oscillometric method detects the pulse wave generated in the process of sufficiently pressurizing the body part through which arterial blood flows so that the blood flow in the artery is blocked and then depressurizing it at a constant speed, or in the process of pressurizing the body part through which arterial blood flows by intensifying the pressure at a constant speed. It is a method of measuring systolic and diastolic blood pressure by detecting the pulse wave that occurs.
- the tonometric method is a method of applying a certain amount of pressure to a body part so as not to completely block arterial blood flow, and measuring blood pressure using the size and shape of a pulse wave generated at this time.
