Problems solved by technology
At present, most of the known portable electronic sphygmomanometers that are relatively simple and accurate use a cuff to wrap the arm and wrist, and use an electric pump to inflate the cuff to apply pressure to occlude the arteries, and then slowly loosen the cuff to obtain arterial pressure. Blood pressure; due to the use of an air pump, a battery with sufficient power is required, such a device is not conducive to reducing size, weight and long-term wear
In order to solve the above problems, Chinese invention patent No. 95197644.3, title "device for measuring blood pressure", and Chinese invention patent application number 200480012661.0, title "blood pressure monitor" propose to use other pressure applying and releasing devices to solve the described problems The solution to the problem has achieved certain results, but because the power pressurization device is still used, it is still not conducive to reducing the size, weight, cost and long-term wearing problems

The invention relates to a method and a device for blood pressure monitoring; wherein, an interception component is used to be positioned on the surface of the living body artery blood vessel skin; firstly, an adjusting device is pushed through a hand or an object held by hand or a screw, the changed push force is executed to the interception component, to ensure that the conducting quantity of an artery vessel is changed, and to ensure that a pulse signal or a blood flow signal and a pressure signal imposed on the interception component or on the artery vessel are obtained by a sensor device during the process of the change of the artery vessel conducting quantity simultaneously, and then a signal processing device is used to explain the pulse signal or the blood flow signal and the pressure signal imposed on the interception component and or on the artery vessel during the process of the change of the artery vessel conducting quantity, thereby determining the practical arterial blood pressure. The invention provides a more advantageous condition for realizing an electronic blood pressure watch and a pen type electronic sphygmomanometer, etc.
Description
Technical field [0001] The present invention relates to a living body vital sign diagnostic device, especially a monitoring method and device for arterial blood pressure, but not limited thereto. [0002] References to related applications [0003] The present invention is a partial continuation of the following Chinese invention patent application: application date: June 25, 2007, application number: 200710127683.7, titled "blood pressure monitoring method and device". Background technique [0004] For most hypertensive patients, it is very necessary to wear or carry a simple and accurate sphygmomanometer for monitoring blood pressure at any time for a long time. At present, most of the known portable electronic sphygmomanometers that are relatively simple and accurate use a cuff to wrap the arm and wrist, and use an electric pump to inflate the cuff to apply pressure to occlude the arteries, and then slowly loosen the cuff to obtain arterial pressure. Blood pressure; due...
