Design And Development Of High-Precision Intelligent Pulse Diagnosis Instrument

Pulse diagnosis,as an important part of China’s TCM diagnosis system,has the advantages of non-invasive and efficient.However,on the one hand,the traditional Chinese medicine pulse diagnosis relies on the doctor’s experience and the feeling under the finger,and the diagnosis result is greatly affected by subjective factors;The problem has long limited the inheritance and development of pulse diagnosis of traditional Chinese medicine.Based on this,from the perspective of realizing the objective of pulse diagnosis of traditional Chinese medicine,this article develops a high-precision intelligent pulse diagnostic instrument that meets the needs of clinical research and application,provides an effective way to objectively reproduce the pulse signal,and combines clinical application Adult pulse waveform development analysis.First of all,based on the analysis of the perception process of pulse diagnosis of traditional Chinese medicine,a sub-pulse tactile pressure sensing model of pulse diagnosis of traditional Chinese medicine is researched and established,which mainly includes the model of human radial artery,probe sensing model and subcutaneous tissue model,etc.The conversion of the pulse process to objective parameters and models,and the use of the finite element method to reproduce the sub-pulse pulse pressure perception and reconstruct the three-dimensional three-dimensional pulse signal.The results show that the built acquisition probe can effectively obtain the signal waveform and the area array multi-point acquisition Obtaining three-dimensional pulse signal shape can extract more detailed pulse information.Secondly,a high-precision intelligent pulse diagnosis instrument is designed around clinical research and application requirements to maximize the restoration or simulation of the pulse diagnosis process of traditional Chinese medicine.A 4R-P series articulated arm pulse-pick and pulse-pick mechanism with 5 degrees of freedom is adopted,and the forward and backward solutions and motion space simulation analysis are performed based on the DH method,which verifies the correctness of the solution and the rationality of the parameters.Rotating joints and manual button control realize automatic rotation of two-handed measurement,cooperate with laser rapid positioning and terminal position and attitude adjustment,flexibly encapsulate the array pulse sensor and pressure sensor and combine with an integrated miniature screw motor to design an intelligent probe,and the pulse taking mechanism is arranged through The four intelligent probes are arranged to achieve full coverage of the inch,close,ruler and underfoot parts,meet the layering accuracy,and meet the precise collection of pulse diagnosis theory single or total fingering,and effectively reproduce the pulse diagnosis process of traditional Chinese medicine.Finally,combined with the clinical acquisition of pulse signals of healthy adults and diabetic patients,and the analysis of pulse data from the time domain and time-frequency domain,the results show that the amplitude and time parameters of the two in the time domain（H₂,H₄,etc.,T₂ etc.）,angle and ratio parameter（α₅）,characteristic index（r AI,AIx,AIx@75,REI）,the energy ratio of the C₄ and C₆intrinsic modal functions in the frequency domain,between 0～2Hz and 0～4Hz There are significant differences in frequency band energy ratio,time domain waveform and marginal spectrum waveform,etc.,which provide a reference basis for objective identification and diagnosis of pulse diagnosis of traditional Chinese medicine for characteristic diseases.
