High-precision intelligent pulse diagnostic instrument

Abstract

The invention discloses a high-precision intelligent pulse diagnostic instrument, comprising a frame component, a probe component and an information acquisition system. The frame component mainly comprises a pulse rest part at the bottom and a frame part arranged above the pulse rest part; the probe component at least comprises four intelligent fingers arranged in parallel; each intelligent fingerhas three driving units and a composite sensing unit. The frame part is connected with the probe component and is used for allowing the probe component to rotate around the arm or linearly move parallelly to the arm, and the arm is placed on the pulse rest part and is driven to rotate or lift; an image acquisition module and an image analysis and positioning module allow positioning and acquiringto be carried out. The high-precision intelligent pulse diagnostic instrument allows automatic alignment, pressure application and pulse signal acquisition to be carried out according to the method of 'five belts, six zones and seven layers', can provide pulse diagnosis for 'five sections and twelve syndromes', and has the advantages of high precision, repeatability and reproducibility; the high-precision intelligent pulse diagnostic instrument is applicable to early warning and diagnosis for clinical diseases, and the problems are effectively solved that, for instance, existing like instruments have low acquisition precision and incomplete acquired signals.

Description

technical field [0001] The invention belongs to the field of medical equipment, and in particular relates to a high-precision intelligent pulse diagnosis instrument. Background technique [0002] Traditional Chinese Pulse Diagnosis (TCPD), as a diagnostic method of Traditional Chinese Medicine (TCM), has gradually formed a diagnostic system of 28 pulse conditions after thousands of years of research and practice in traditional Chinese medicine. At present, the main way of TCM pulse diagnosis is still that TCM physicians perceive the patient's pulse condition through their fingers, and then diagnose diseases based on the physician's experience and tactile sense of hands. The judgment standard of this diagnostic method is vague, and it is easy to be misjudged by the personal experience and subjective factors of the physician, and it is impossible to quantify and effectively record the pulse condition. [0003] Therefore, in recent years, many scholars at home and abroad have ...

AI Technical Summary

Problems solved by technology

However, the above-mentioned instruments are limited to the acquisition of the three pulse signals of inch, guan, and ruler, ignoring the pulse signal under the ruler, resulting in the loss of collected information

At the same time, the above-mentioned patents do not clarify the difference between the instrument itself and the human finger, and both adopt the vertical downward pressure mode, ignoring the influence of the finger bending force on the collection process by the TCM doctor when collecting the pulse signal, and cannot completely Simulate pulse signal acquisition process

Patent CN103263256 simulates the multi-degree-of-freedom pulse diagnosis process of TCM physicians by designing multiple humanoid fingers, which better solves the problem of interference of the actuation force on the pulse sensor during collection, but due to the lack of positioning references and wrist positioning devices, during detection, It is easy to cause changes in the detection area and cause a large deviation in the collected pulse signal

Moreover, the instrument uses a pneumatic transmission device to apply pressure. Due to the high compressibility of air, the accuracy of position control is not high, and it is difficult to ensure the repeatability and reproducibility of the acquisition process.
