Summer hot high temperature, I believe everyone has already opened the "air-conditioned + cold drink" mode. However, if you blow the air conditioner for a long time, drink cold drinks, the stomach can not stand it. Plus the summer high temperature, food is particularly prone to deterioration, if you eat these metamorphic food, gastrointestinal disease will definitely follow.
I have got gastrointestinal disease, only to go to the hospital, and some inspections related to gastrointestinal diseases often "smell the wind", such as gastroscopy, colonoscopy ... I feel very painful, let many people are looking for.
Therefore, a gastrointestinal inspection technology with non-invasive painless and convenient and convenient, "capsule endoscopy" came into being.
What is a capsule endoscope? As the name, it is an endoscope like a capsule.
It is like a miniature "submarine" installed with a miniature camera. When the patient swallowed this "small submarine", it will drive in the stomach, and then transmit the gastrophe to the in vitro receiving box through the wireless manner. Such doctors can pass these images to diagnose the diagnosis of diseases.
You see, is this method really "non-invasive painless and convenient"? However, this "small submarine" is only installed with a camera. In the clinic, only a single image information, doctors often cannot accurately diagnose gastrointestinal diseases.
If the physiological parameters of the gastrointestinal environment can be collected, such as acid alkalinity, susceptible blood content, etc., will help doctors will make more accurate diagnosis.
Recently, under the support of the National "Twelfth Five-Year" Science and Technology Support Program, Liu Hao, Institute of Automation, Chinese Academy of Sciences, studied, studied, Yang Yun, Professor, Yang Yuncheng, the General Hospital of the People's Liberation Army, China, etc., Chongqing University, etc., the gastrointestinal test and imaging The micro system has conducted in-depth studies, developed three more "small submarines", named "composite diagnosis capsule endoscope", "upper digestive tract pH capsule endoscope", and "gastric hidden blood test Capsule endoscope.
Then let's introduce this three "small submarine".
Composite diagnosis capsule endoscope: There is a picture with parameters, at a glance
If a single image information is somewhat thinner for diagnosis, then let the capsule endoscope bear more test tasks!
Left one is a composite diagnostic capsule endoscope, compared to the one-dollar coin on the right, it is clear.
In gastrointestinal disease, slight polyps or inflammation gradually aggravate or even deteriorate the disease such as tumors, there is a process, and the morphology of the lesion in the conversion process, the human secretion material or local micro-alive environment is different, then choose the right physiology Parameter sensors (such as pH, temperature or oxygen-containing amounts such as sensors) combined with image sensors to achieve multiple information fusion diagnostics will be a big span.
Composite diagnosis of capsule endoscopes, this "small submarine" outstanding characteristics, of course, "composite". It integrates Physiological parameters and image sensing acquisition modules such as pH, and transmits these fusements into vitro using wireless communication.
Don't look at the composite diagnostic capsule endoscope small one (diameter 12mm, length 36mm), but at work, it can not only provide a doctor's intuitive video information, such as suggesting that there is bleeding point here, but also provide testing Some physiological parameters such as pH in the intestine.
In this way, the composite diagnostic capsule endoscope can maintain morphological observation and environmental parameter monitoring consistency in time and space, providing a more sufficient and stereo diagnosis for the diagnosis of gastrointestinal diseases, such as helping hemorrhagic diseases. (Tumor, ulcer, etc.).
Upper gastrointestinal pH capsule endoscope: "Submarine" on the esophageal wall
The left figure is the upper deactivation pH capsule endoscope, and the right figure is a schematic diagram of its fixing in the esophagus arm, and the continuous acquisition pH is transmitted to the body in a manner of wireless communication.
The endoscopic pH capsule endoscope is mainly used in the diagnosis of the condition of "gastroesophageal reflux". The gastroesophageal reflux refers to the refractive flow of the stomach, which can cause Barrett eater and esophageal cancer. When treating the gastrointestinal reflux, the pH of the digestive tract is needed.
That is, we need to develop a "small submarine" that can "hang" on the esophageal wall, allowing it to monitor and report the digestive tract for several days.
The endoscopic pH capsule endoscope is such a "small submarine". It is capable of attaching an esophageal mucosal tissue at a particular location above the esophagus, and is reliably secured to the mucosa by the internal micro mechanism. This solves the continuous discomfort and pain caused by traditional catheter detection.
At work, it stably climbed on the esophagus wall, and can monitor the acid-alkalinity in the esophagus for four days and four nights. The software can be displayed and printed and the pH curve is printed, and the data statistical analysis report is automatically generated. A little helper.
Gastric hidden blood test capsule endoscope: Baiwai with "swallowed"
The above figure is that the gastric hidden blood detection capsule endoscope is mainly composed of vase blood sensor and its detection module, the detection result acquisition module and the radio frequency communication module, and can be directly viewed as the coin of the following figure. The size of the capsule endoscope.
The gastric hidden blood test capsule endoscope is the "submarine" that can detect gastric hiking.
The early tumor injury mucosa will produce very small amounts, so that the blood that cannot be observed with the naked eye, this blood is also called "hidden blood", which can expose a big problem. Therefore, the testing of gastric hidden blood has important diagnostic significance.
How to detect? Conventional methods are hidden blood prevention. When checking a size close to the capsule and put the hidden blood of the thin line in the mouth, the wire is left in the mouth, and the hidden blood is sent into the stomach by drinking water. Finally, the hidden blood will be pulled out, you can think I want the picture ...
It is not necessary to use the stomach blood to detect the capsule endoscope. The specific valence-free sensor mounted in this "small submarine" is targeting human hemoglobin. It is possible to detect whether it is positive without the need for external intervention, and the detection result is collected by the acquisition module.
Swallowing this "small submarine", which can detect micro blood as low as 0.19 μg / ml concentration through external signal receiving devices! This test has important guiding significance for the diagnosis of early gastric cancer.
During the gastric hichaletsis detection, the patient has a signal receiving apparatus in the waist, transmitting the vapory blood of the stomach to the body by wireless communication by the swallow capsule endoscope.
Seeing that someone may have a question here, how do you go to the stomach? In fact, the answer is simple, the capsule is one-time, so don't take it after the check, through natural excretion, let the small submarine flow into the sewer, is it very convenient?
These three digestive diseases diagnose capsule endoscopes, that is, "small submarine" products enrich medical staff's diagnostic means for relevant diseases, providing safe, comfortable and more effective disease diagnosis tools for patients, reaching International leadership. How to make medical tests more comfortable, let the test results are more reliable, researchers have been working hard!
