Multi-part pulse wave acquisition device

Abstract

The invention discloses a multi-part pulse wave acquisition device which comprises an acquisition fixing module, acquisition modules, a pressurization module, a main control module, a communication module and a power supply module, and is characterized in that the acquisition fixing module comprises adhesive wrist straps, a magnetic suction support, a supporting frame and an anti-skid layer, and the strip-shaped magnetic suction support is embedded in the upper part of the supporting frame; the lower part is provided with the anti-skid layer, and the two sides are sewed with adhesive wrist straps; each acquisition module comprises an air bag, an ejector rod, a reset spring, a permanent magnet and a pulse wave sensor, and the three acquisition modules are cuboid-shaped and are adsorbed on the magnetic suction support of the acquisition fixing module in a magnetic manner; the pressurizing module comprises an air pump, a micro air storage tank, a first electromagnetic valve, a second electromagnetic valve, a pressure stabilizing valve and an air pipe; the master control module comprises an STM32 single-chip microcomputer, an upper computer and an LCD screen; and the communication module comprises a USB driving chip and a USB driving circuit. According to the present invention, multi-part selection can be achieved, operation is easy and convenient, and pulse wave signals can be stably obtained.

Description

technical field [0001] The invention relates to the technical field of pulse wave detection, in particular to a multi-part pulse wave acquisition device. Background technique [0002] Pulse diagnosis is one of the important methods of TCM clinical diagnosis of diseases. Under the guidance of TCM theory, the doctor senses the pulsation status of the patient's bilateral wrist radial arteries with fingers, and comprehensively judges the health status of the human body together with other diagnostic methods. With the deepening of the modernization of traditional Chinese medicine, the study of pulse diagnosis in traditional Chinese medicine has been widely carried out with the help of modern technology. The important technical condition required for this research is to be able to obtain pulse wave information stably. [0003] The digitization of pulse wave is the premise of realizing the objectification of pulse diagnosis in traditional Chinese medicine. The current pulse wave ac...
