Monitoring method and device for blood pressure

Abstract

The present invention relates to blood pressure measuring method and device. One blocking element is first set on skin surface corresponding to artery vessel and certain push force is applied onto the element to block the artery vessel, the push force is then reduced in certain rate for the artery vessel to dredge gradually while some sensor device is adopted to obtain the pulse signal and the pressure signal on the blocking element or the artery vessel during the period from blocking to complete conducting, and one signal treating device is adopted to determine the practical artery blood pressure. The present invention provides favorable condition for new type of electronic blood pressure measuring wrist watch, pen type electronic blood pressure meter, 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. Background technique [0002] 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 to the use of an air pump, a battery with sufficient power is required, and such a device is not conducive to reducing the size, weight and long-term wear. In order to solve the above problems, Chinese invention patent No. 95197644.3, title "device fo...

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
