Description
Technical Field
The invention relates to the technical field of pulse feeling, in particular to a human pulse remote bionic reduction system and method.
Background
In recent years, remote medical diagnosis and treatment work on patients are realized through an Internet platform, the common pressure of medical institutions and patients is reduced, the civil problem of 'difficulty in seeing diseases and high price' of patients is solved, the method is the direction of efforts of people government at all levels, and the method is also the direction of cumin tiredness of medical institutions at all levels and the Internet+medical platform, and is in effort to chase and develop. Through the efforts of the last 20 years, the 'Internet+medical' industry in China is from nothing to nothing, and from the existence to the large-area spreading, the whole network medical industry is greatly improved and developed. The development of the services such as online registration, online consultation, online inquiry and the like provides convenience for the medical treatment of patients. Meanwhile, the completion of the corresponding various network medical computer software development works lays a foundation for further development of the Internet and medical work in China, and contributes to pushing the Internet and medical work in China.
However, in the advancing process of the whole internet+medical industry, besides the hysteresis problem of the related policies, some technical problems and the like which are still to be solved in the technical links of the related internet+medical industry are difficult to implement and land in the internet+medical industry. Such as: the 'network + medical' problem of traditional Chinese medicine.
As a major component of network medical treatment, the national traditional Chinese medicine "network+medical treatment" is always the key breakthrough direction of IT network medical platform and medical institutions. The main reason is that: 1. compared with Western medicine, the traditional Chinese medicine is easier to realize diagnosis and treatment in remote medical treatment. The method is mainly established in the traditional Chinese medicine, and the disease diagnosis work of a patient can be finished only by a unique four-diagnosis method (namely inspection, smelling, inquiry and diagnosis) without any medical examination and examination equipment. 2. Practice proves that: the traditional Chinese medicine has curative effect advantages on chronic diseases, senile diseases, bone diseases, difficult and complicated diseases and the like, and has uniqueness on the treatment of the ill diseases and the health care and health preservation, so that the diagnosis and treatment of the Internet and the traditional Chinese medicine on the Internet are urgently needed for the patient group with the requirements of traditional Chinese medicine. 3. Compared with Western medicine, the diagnosis and treatment cost of traditional Chinese medicine is relatively low, and the traditional Chinese medicine is easier to be accepted by patients. However, through efforts in these years, although the platform of "internet+traditional Chinese medicine" in China is hundreds, so far, no platform of traditional Chinese medicine network medical treatment in China can really and thoroughly develop the remote diagnosis function in the four diagnosis method of traditional Chinese medicine technically, thereby causing the embarrassment that traditional Chinese medicine network medical treatment cannot fall to the ground.
The reason is mainly because the pulse-feeling technique is the most unique diagnosis method in ancient traditional medicine in China, and is also the most classical, complex and most informative diagnosis method in the four diagnostic methods of seeing, asking, smelling and cutting in traditional Chinese medicine, and meanwhile, the pulse-feeling technique is the most important basis of the differential medical treatment of the traditional Chinese medicine. The three kinds of diagnosis of the traditional Chinese medicine 'four diagnosis methods' can be intuitively implemented, and the 'pulse feeling' is needed to sense the pulse condition of the human body by hand, so that doctors can know the conditions of all viscera in the patient.
Currently, the products developed and applied by various large medical platforms are mainly two types. The method is characterized in that the acquired pulse information is converted into an electric signal through conversion of a vibration signal of the pulse, and the electric signal is remotely transmitted to a terminal display screen to be reflected in a pulse wave form; the other is to use the same pulse acquisition and transmission method, but to display the signals on the display screen in a pulse chart mode. Although both the pulse condition acquisition and remote transmission modes are objective for collecting pulse condition information, the problems of the two pulse condition acquisition and remote transmission modes make the two pulse condition remote diagnosis methods difficult to popularize and apply. The problem is mainly reflected in the following aspects: 1. the two pulse condition acquisition modes are mostly based on the experience of one or a group of old traditional Chinese medicines, and the model is built by taking the cognition of the traditional Chinese medicines on the pulse condition as a standard, so that the objectivity, the sample size and the acceptance degree of other teachers and students are influenced. 2. The existing two remote pulse condition terminal display methods are not easy to be accepted by clinical science because the defects of single pulse condition, weak repeatability and the like can not be perfected all the time though development.
