The traditional diagnostic method of Chinese medicine in China is nothing more than four words: look, smell, ask, cut. In fact, everything is inseparable, and modern medical treatment is just an evolution on this basis, using scientific and technological means to exceed the limits of the human body's own audio-visual, and then more accurately diagnose the pathology.
In recent years, it has become popular on the Internet to use scanners to scan parts of your body. This may be just a performance art. However, if you can read the body image presented by the instrument like a doctor, it is not impossible to further diagnose small acne problems on your face. Moreover, with the modernization and digitization of science and technology, some diagnostic technologies can even allow doctors to compare and diagnose patient images on mobile phones, Pads, or computers with professional analysis software, or patients can travel thousands of miles through the Internet. Experts outside the hospital conduct consultations.
This way, "seeing a doctor" is true
Generally sick, we often say to go to "see a doctor". In fact, the word "see" here is a passive word, which means "to be seen by a doctor", but the question is, can a doctor really see it? In fact, in the past, doctors could not see anything because human eyes are similar.
And if the doctor really wants to understand the internal pathology of the patient's body, in addition to direct dissection (generally less than a last resort, doctors and patients are unwilling to do so), they can only rely on "palpation", as is common in medical examination Abdominal compression is the most basic palpation. However, these two methods are different from the performance art of using a scanner to sweep your face. Then the latter seems to be more precise. Don't worry, doctors can use modern medical imaging technology to achieve.
In 1895, German physicist William Conrad Roentgen discovered X-rays. For the first time, humans saw the internal bones of living bodies through instruments. Nowadays, the equipment that can "scan" the body inside the hospital is more and more diverse and more advanced, such as X-ray fluoroscopy equipment, computed tomography (CT), nuclear magnetic resonance imaging (NMRI), etc., most of them are placed like baby In the well-protected radiology department of the hospital.
How to use nuclear magnetic resonance to allow doctors to see stereoscopic images in the body? Not to mention, this device is a bit like the microwave oven commonly used in the home, but the patient is not lying in the microwave oven for examination. Microwave ovens can only oscillate molecules in food, and nuclear magnetic resonance is to oscillate hydrogen nuclei, which is an important part of water, and about 70% of the human body is composed of water. When the human body enters the magnetic field of the device, the appropriate electromagnetic waves will change the direction of the hydrogen atoms in the body. After the radio frequency, the hydrogen nuclear energy returns to the initial energy state. At this time, the electromagnetic waves generated by resonance are emitted, and the atomic vibration The difference can be accurately detected, and finally processed by the computer to obtain a three-dimensional image of the reaction histochemical structure. The doctor uses this map to analyze and diagnose the corresponding pathology.
It can be said that with modern medical imaging technology, doctors have really realized "seeing a doctor".
Absolutely hear physical abnormalities
The so-called "smell" in Chinese medicine does not mean to sniff with the nose, but to identify and diagnose by listening to the patient's talk, breath, cough, etc. Although there were no tools similar to modern "stethoscopes" at that time, it was indeed an effective method to use "sound" to judge the lesions in patients. For example, some common respiratory diseases, under the stethoscope, will emit a frequency similar to irregular "shock" under the ground, and experienced doctors will use this to accurately diagnose the condition.
Now, the basic principle of auscultation has been inherited by modern detection equipment and communication methods. Not long ago, several scientists at the University of Melbourne, Australia, jointly developed a set of software called "Stetho Cloud" that can turn a smartphone into a remote stethoscope. With such a device, a preliminary diagnosis of the condition can be made, but the exact treatment Still need a doctor to meet in person.
Stetho Cloud software is used by inserting a dedicated auscultation head into the earphone interface. The software will guide the user to perform the corresponding operation through the wizard mode, and the doctor can listen to and record the patient's breathing sound. When the software has obtained enough data, it will automatically upload the data to the server located in the cloud, and eliminate the noise for analysis. This set of intelligent software is suitable for the initial diagnosis of pneumonia.
In addition, the ultrasonic diagnostic equipment commonly used in modern hospitals breaks through the traditional method of diagnosis by sound, and can "hear" the images inside the body. The so-called ultrasonic wave refers to the sound exceeding 20000 Hz, because the human hearing range is 20-20000 Hz.
During the ultrasonic examination, the device will emit a set of ultrasonic waves to the human body. Due to the different reflection strength of different tissues, the distance and nature of the organ can be judged according to the delay time and strength of the monitoring echo. Then, after processing by the computer, an ultrasound image of the cross section is formed, and the doctor can analyze the human body according to the image and judge the pathology. Generally speaking, ultrasonic testing is divided into A-type, B-type, M-type, D-type, etc. according to the different sound wave frequencies used. B-mode ultrasound is the most commonly used in hospitals, because its cross-sectional view usually shows the specific situation of the tissue being probed, which is more practical.
After the development in recent years, the ultrasonic diagnostic equipment has been continuously improved, and now the world is only the size of a mobile phone, it is the Vscan launched in 2009. Users can use the Scam probe to touch the skin to make black and white or color B-mode ultrasound. At this time, the internal state of the body can be displayed on the screen in real time, and it can also use the SD card to store the imaged images for further storage and copying. Such a small ultrasonic device can be carried around with you, and it is even more "listening" than the stethoscope on the neck of the doctor. However, it should be reminded that the device is still a medical device after all, and it should never be self-diagnosed based on experience. The consequences are self-evident.
