Description
Technical Field
The invention relates to the technical field of medical instruments, in particular to a pulse condition detection system based on a flexible array sensor and a manufacturing method of the flexible array sensor used for the pulse condition detection system.
Background
TCM is a treasure of Chinese nationality and is a medical discipline for studying human physiology, pathology, and disease diagnosis and prevention. The pulse condition is an important basis for the diagnosis of traditional Chinese medicine, which refers to the condition of rapid, slow, strong, weak and deep pulse, and is the image and dynamic display of pulse. In the process of traditional Chinese medicine diagnosis, doctors determine pulse conditions by feeling pulses. The pulse feeling process is as follows: the doctor of traditional Chinese medicine applies different pressures to the cun, guan and chi parts of the patient's radial artery by three fingers to feel the process of different pulsation of the patient's artery. Because the traditional Chinese medicine diagnosis of pulse conditions depends on the subjective feeling of doctors on pulse fluctuation, the feeling of fingers cannot be expressed accurately and quantitatively, and thus the traditional Chinese medicine diagnosis cannot be accepted by broad scholars. Further, since the pulse condition is limited by the level of the doctor and the accuracy of the physical perception, the accuracy of pulse condition diagnosis and the practical application in modern medicine are greatly restricted.
At present, there are two main types of mechanized pulse diagnosis devices. The first is a large pulse diagnosis device used in professional places such as hospitals, and the device has a complex structure and a high use threshold, and can acquire a good pulse signal only by the accompanying guidance of professional medical care personnel, so that the device is difficult to adapt to the convenient development trend of modern medical treatment and is not beneficial to wide popularization. The second is a portable household pulse diagnosis instrument, which is convenient to use and relatively random in use scenes, but has high purchase cost, does not visually present the collected human body pulse distribution signals, and cannot give specific analysis principles and corresponding relations of the pulse of a user.
The main component of the mechanized pulse diagnosis equipment is a pulse condition sensor. Currently, pulse condition sensors include single point pulse condition sensors and array pulse condition sensors. The single-point pulse condition sensor only collects pulse signals at the radial artery in a single point mode, and judges the pulse condition of a human body by analyzing two-dimensional pulse signals through a time domain analysis method. The arrangement of each unit sensor in the existing array pulse condition sensor is scattered, and the positioning is not reasonably carried out according to the position of the cun, the chi and the guan of the radial artery of a human body, so that three-dimensional pulse condition signals can be collected, but the disordered signal distribution is not beneficial to the pulse condition signal analysis. Furthermore, most of the existing pulse condition sensor arrays are based on a silicon-based hard circuit board, and each sensor unit device is also made of a rigid material, so that the curved surface fitting degree of the wrist of a patient is poor, the acquisition accuracy can be influenced, and the wearing comfort is low
