Abstract

The invention relates to a medical treatment device and a pulse monitoring technology, in particular to a pulse diagnosis instrument on the basis of multipoint pressure sensors. The pulse diagnosis instrument is characterized in that three pressure sensors are arranged on a pulse diagnosis shell and comprise bases with suspending holes, a layer of graphene wall is laid below each base and is connected with polymer force-sensitive thin films, pressure-sensitive bumps are connected with the bottoms of the polymer force-sensitive thin films and correspond to the suspending holes, graphics strips are periodically arranged on the graphene walls, and wrinkle or crack structures are arranged on the graphene walls and the polymer force-sensitive thin walls; the three pressure sensors correspond to Cun, Guan and Chi locations and are electrically connected with circuit modules. The pulse diagnosis instrument has the advantages that the pressure sensors are high in sensitivity and can cling onto the wrists of users, accordingly, pulses of the users can be measured by the pressure sensors, pulse conditions can be judged, and the pulse diagnosis instrument is suitable for places such as family and hospitals.

Description

technical field [0001] The invention relates to a medical device and a pulse monitoring technology, in particular to a pulse diagnosis instrument based on a multi-point pressure sensor. Background technique [0002] Pulse condition is the image that pulsation should refer to. The generation of the pulse condition is directly related to the fluctuation of the heart, the ups and downs of the heart qi, the smoothness of the channels and the profit and loss of qi and blood. Therefore, the heart and the pulse are the main organs that form the pulse condition. Qi and blood are the material basis for forming the pulse condition. At the same time, the blood flows along the meridians, spreads throughout the whole body, and runs continuously. In addition to the leading role of the heart, there must also be the coordination and cooperation of various organs: the lungs are directed towards the various meridians, the lung qi is applied, and the blood releases energy to spread; the sple...
