Description
Technical Field
The utility model relates to an electronic sphygmomanometer, in particular to an electronic sphygmomanometer with an adjustable wrist strap.
Background
The wrist electronic sphygmomanometer is significant for monitoring blood pressure, paying attention to blood pressure fluctuation, assisting doctors in diagnosing prescriptions and monitoring and treating hypertension. The working wrist electronic sphygmomanometer firstly bundles the cuff on the arm, then automatically inflates the cuff, stops pressurizing after a certain pressure is reached, and then starts deflation. When gradually deflating you will see the screen display oscillating wave number getting larger and larger. The cuff is deflated again after the number reaches a maximum point, and the deflation is caused by the fact that the contact between the cuff and the arm is gradually loosened, and the value on the pressure sensor is smaller and smaller. The principle of the method is to adopt an oscillometric method, which is also called a concussion method, namely, the cuff is pressurized until the blood flow of the brachial artery is blocked, then the pressure is slowly reduced, and sound and small pressure pulses are transmitted from the arm in the meantime. Finally, the apparatus can self-identify the small pulse transmitted from the arm to the cuff, and also identify the systolic pressure and the diastolic pressure, so as to obtain the blood pressure value, and thus, the user can easily, simply and clearly know the own blood pressure value.
However, in the using process, the wrist thicknesses of various people are different, the tightness of the binding cuff is too loose, the air filling amount in the air bag is more than that in the normal state, and the measured blood pressure is higher than the actual blood pressure; if the pressure is too tight, the arterial blood flow can be blocked by a small amount of inflation (pressure in the cuff) in the air bag, so that the measured blood pressure is lower; the position of the cuff is too low, the air bag which actually presses the brachial artery is narrowed, at the moment, more inflation quantity is needed to block the blood flow of the artery, and the measured blood pressure is higher than the actual blood pressure. Or the body position and the posture are incorrect, or the measuring environment has larger noise influence, so that the measured value of the machine has deviation or error.
