The collection system design of pulse information based on the USB technology

摘要

Pulse diagnosis has been widely applied to clinical practice. The key of palpation diagnosis is the human perception and the comprehensive analysis of various pusle symptoms, but the subjective judgement errors sometimes exists. In the paper, the collection system of pulse information with the kernel of high-speed microcomputer C8051F040 is realized by pulse sensor of HK-2000G. The communication of pusle information is completed between C8051F040 and PC through CH375 of USB interface, and the pusle information can be showed on PC screen. Thus benefites to that doctors objectively gain the healthy information of body and analyse pathogeny according to the pulse information change.
