Watch strap human blood pressure non-invasive continuous detection device

Abstract

The invention belongs to general electronic blood pressure measuring apparatuses, aiming at providing a wristlet typed human body blood pressure trauma-free continuous checkout gear for realizing theconvenient and comfortable continuous blood pressure measurement. The technical scheme adopted by the invention is that the wristlet typed human body blood pressure trauma-free continuous checkout gear consists of two parts of a wristwatch and a human body pulse wave checkup gear, and the two parts are connected by a wristlet and an electric signal wire; the human body pulse wave checkup gear consists of a piezoresistive pulse wave sensor and a base of the pulse wave sensor; a pulse wave signal processor unit is attached to the inside of the wristwatch of the wristlet typed human body blood pressure continuous checkout gear; the wristlet consists of a pressing belt of the pulse wave sensor, a sensor location adjustment strip, a length size regulating mass used for regulating the length ofthe wristlet, a camber regulating mass used for regulating the measuring point locating relation between the wristlet and the pulse and a fastening belt. The checkout gear is mainly used for manufacturing blood pressure continuous monitoring and measuring apparatuses.

Description

technical field [0001] The invention belongs to a general electronic blood pressure measuring device, in particular to a wristband type human blood pressure non-invasive continuous detection device based on pulse wave characteristic parameters. technical background [0002] At present, blood pressure measurement is mainly divided into two categories: invasive measurement and non-invasive measurement. Invasive measurement is a direct method in which arterial blood pressure is measured by inserting a catheter into an artery. This method needs to be operated by professional medical personnel, the cost is high, and it is easy to cause bacterial infection. Non-invasive is an indirect measurement method. This method is safe and convenient to use, and is currently a commonly used blood pressure measurement method in clinical practice. [0003] Non-invasive measurement mainly includes auscultation (Krotkoff sound method) and oscillation method (oscillometric method). The princip...

Problems solved by technology

The device can not only overcome the shortcomings of the traditional blood pressure measurement method, which are usually bulky and inconvenient to carry because it includes cuffs, pumps and valves, but also avoid the inaccurate repeated positioning of existing pulse wave measurement devices
