Objective:To study the finger-type pulse manifestation acquisition device adapted to the individual needs of the collectors with 3D printing technology as a tool,and carry out research on pulse analysis algorithm based on pulse factors to provide reference for objective research and clinical application of pulse diagnosis.Methods:Using 3D printing technology,a finger-pressing three-part pulse image acquisition device was designed and manufactured,and pulse image data were collected.On the basis of searching wave crest and trough data through data traversal,pulse analysis algorithm based on pulse elements was studied.Results:①Using 3D printing technology,we can design and fabricate a pulse collection device which is suitable for pulse collector’s finger.When wearing this device,collector can simulate doctors’ clinical pulse diagnosis and obtain more comprehensive pulse data information.②On the basis of identifying wave peaks and troughs,the ratio of the number of wave peaks (or troughs) to the time can be used to determine the slow or rapid of pulse rate.The ratio of the ratio of the peak value and the average of the peak-to-trough value can be used to determine the strength or weakness of pulse potential.As well,the floating or sinking of the pulse position can be determined by comparing the ratio of the pulse force at different times of floating in sinking.③By implementing the pulse analysis algorithm mentioned above,not only can ensure the pulse condition of floating or sinking,slow or rapid,vacuous or replete,but also the unique pulse condition of a certain part can be found,and the changes of pulse condition elements can be dynamically observed in the course of disease development,which can be used as a reference for clinical diagnosis and efficacy evaluation of diseases and syndromes.Conclusion:Introducing 3D printing technology into the development of pulse acquisition device can provide useful technical tools for the objectification of pulse diagnosis.The pulse condition element analysis algorithm based on self-contrast can provide important pulse condition information for clinical diagnosis and treatment,which is conducive to promote the objective study of pulse condition diagnosis to clinical application as soon as possible.
