Abstract

The invention discloses a blood pressure measuring device which comprises an arm sleeve and a main unit. The main unit is connected with the arm sleeve, an upstream air bag and a downstream air bag are respectively positioned on a blood flowing upstream location and a blood flowing downstream location of the artery of the tested limb of a user, the downstream air bag is used for instantaneously detecting change information of pulse signals and senses change of blood flowing pulses due to change of the pressure of the upstream air bag in real time, a microprocessor controls air pumps and air release valves and processes pulse values, the pulse signals or combinations of the pressure values and the pulse signals of one of the upstream air bag and the downstream air bag or both of the upstream air bag and the downstream air bag, and the pressure values, the pulse signals or the combinations of the pressure values and the pulse signals of the upstream air bag and the downstream air bag are respectively detected by one of a first pressure sensor and a second pressure sensor or are simultaneously detected by the first pressure sensor and the second pressure sensor. The blood pressure measuring device has the advantages that the two inflation air bags are bound on the limb of the user to pressurize the limb of the user, accordingly, the blood flowing pulses which can be used for testing the blood pressure of the tested limb of the user can be effectively detected from binding bands of the upstream air bag and the downstream air bag, the pulse signals in the blood flowing pulses can be effectively detected, the blood pressure can be accurately and reliably measured, and measurement results are stable.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a method for detecting arterial blood pulse signals and a blood pressure measuring device using the method, especially a method for simultaneously controlling the upstream and downstream blood flow of a limb through two inflatable airbags. A method for detecting pressure and pulse signals and a blood pressure measuring device based on the method. Background technique [0002] One of the most commonly used methods of blood pressure measurement is to use a cuff with an inflatable air bag, which first blocks the arterial blood flow of the limbs of the human body through pressurization, and then slowly decompresses. The Korotkoff sound generated when blocking the area, or the change value of the pulse wave signal strength generated by the arterial pressure in the cuff, determines the systolic and diastolic blood pressure of the arterial blood.
