Abstract
The invention discloses a closed mercury-free sphygmomanometer for measuring the blood pressure of a human body. A pressurization inflating ball is used for inflating and pressurizing a cuff bound on the arm of a user through a pressurization inflating tube. Air pressure in the cuff inflates and pressurizes a corrugated tube sealed in a liquid storage barrel filled with liquid through a communicating air tube, so that the corrugated tube stretches or retracts to squeeze the liquid in the liquid storage barrel to pass through a liquid communicating tube three-way elbow and a glass tube with blood pressure graduated scales on the surface to flow up and down in the glass tube along with the changes of blood pressure, and meanwhile a light spot formed after light emitted by a laser phototube below the three-way elbow is irradiated to a liquid column in the glass tube through a glass blocking piece flows as well. The gas portion at the upper end of the glass tube is in sealed connection with a gas storage barrel with negative pressure through a venting tube, and therefore the liquid and gas can flow up and down in the glass tube in a completely-closed state. A heart rate sensor is arranged in the cuff to measure the heart rate, and heart rate data are displayed on a heart rate digital displayer.
