Description
Technical Field
The invention relates to the technical field of traditional Chinese medicine diagnosis and treatment instruments, in particular to a remote pulse feeling sensor.
Background
The traditional Chinese medicine field covers over 2000 years of extensive medical practice in China, and comprises various practical methods of acupuncture, herbal medicine, massage and other methods for helping patients to recover. To date, traditional Chinese medicine has become an indispensable part of medical diagnosis. According to the treatment concept of the traditional Chinese medicine, the patient can be caused by the abnormal internal and external environments of the body, and the internal environment of the patient can be adjusted to achieve the balance of yin and yang, so that the patient can be eliminated. The main diagnostic methods in TCM are inspection, auscultation, inquiry and resection, and the first is pulse diagnosis (resection) and tongue diagnosis (inspection). Accurate diagnosis of pulse conditions can be achieved only by years of study, time and diligence of traditional Chinese medical practitioners.
Because the diagnosis of the client in traditional Chinese medicine usually requires four diagnostic methods of inspection, sniffing, inquiry and palpation, the pulse diagnosis refers to the method of palpation by touching the pulse condition of different parts of the human body to observe the change of pulse condition, which is also called pulse feeling, pulse pressing and pulse holding. The formation of the pulse condition is closely related to the qi and blood of the zang-fu organs, and if the qi and blood of the zang-fu organs are affected, the blood circulation will be affected and the pulse condition will change. The pulse diagnosis is clinically used to infer the prognosis of disease. Clinically, the pulse-taking time and the body position of the patient are mainly grasped, the finger movements and finger strength of the doctor are light and heavy, the pulse-taking time is limited to that each pulse condition beats not less than 50 times, and the pulse-taking can be correctly carried out only by knowing the change of the pulse condition of a healthy person. The pulse-taking adopted by ancient Chinese medicine in the aspect of diagnosing diseases is a unique pulse-taking method (pulse method), is a part of the 'diagnosis-based' in the 'four diagnosis-based' of traditional Chinese medicine (inspection, auscultation, inquiry and cutting), and is also an indispensable objective basis for diagnosis and treatment based on syndrome differentiation.
When feeling pulse, TCM physicians can determine the cause of disease according to the pulse condition of the patient, such as rhythm and strength, and prescribe a prescription based on the cause of disease. After the doctor of traditional Chinese medicine has a pulse-cutting diagnosis, the commonly used treatment prescription is traditional Chinese medicine decoction.
Telemedicine diagnosis, i.e. providing telemedicine services by technical means, has become a widely accepted medical practice at home and abroad. With the electronic medical information exchange and the use and development of remote medical treatment for helping patients to realize physical health, the combination of traditional Chinese medicine and remote medical treatment can bring further health guarantee to people with various demands.
The wrist of the human body has 9 parts to provide the most valuable pulse condition information for pulse diagnosis, 28 kinds of 'features' in the pulse condition need attention and analysis of traditional Chinese medical doctors, the combination of different pulse conditions can also influence the diagnosis result, and the possibility of different patients can be obtained by carefully reading and distinguishing the collected information.
With the development of modern advanced communication technologies, hospitals, health institutions, and private doctors are constantly expanding the use of telemedicine in medical practice today through e-mail, smart phones, and other wireless tools. Telemedicine can help patients in remote areas, nearby, without hospitals and medical personnel to obtain medical services. In addition, the patient can conveniently communicate with the doctor through videos and emails to obtain medical services without visiting a clinic or a hospital in person.
Other advantages of using telemedicine include: the real-time image and voice communication shows the vital signs to the doctor, and transmits the disease video of the patient. In addition, telemedicine can also monitor and acquire the health condition and data of a patient at a remote place in real time for analysis by a medical institution. The data may include specific vital signs such as blood glucose, electrocardiogram, and the remote medical service may eliminate the inconvenience of the patient going to the hospital or asking the doctor in person. Telemedicine may also be used to provide continuous professional education for healthcare providers or medical tutorials for students in remote areas, which may help improve the health of people in the area and reduce the incidence of common illnesses.
Traditional Chinese medicine has become a common medical method in China and some western countries, remote medical treatment is introduced into the field of traditional Chinese medicine treatment, and recent practices show that the remote medical treatment can effectively treat patients in the field of traditional Chinese medicine. Traditional Chinese medicine can coexist with western medicine, is complementary to the western medicine, and is favored by some patients. In the 21 st century, with the technological innovation in the medical field, the willingness of the medical industry to perfect remote medical treatment is more urgent, and the intelligent pulse diagnosis product of the traditional Chinese medicine is also called.
