Description

Gastrointestinal Bleeding Intelligent Detection System

Technical field:

The invention relates to an intelligent detection system for intestinal bleeding, which is used for non-invasive detection of gastrointestinal bleeding.

Background technique:

Intestinal bleeding is a common gastrointestinal disease in clinical practice. Severe intestinal bleeding can lead to acute anemia and hemorrhagic shock, and even endanger the lives of patients. Before treating intestinal bleeding, accurate positioning of the bleeding site is the key. Only by accurately locating the bleeding site can effective follow-up treatment be carried out. The physiological structure of the human intestinal tract is complex, especially the small intestine, which is long and has many bends. As a result, patients often fail to receive timely and accurate treatment during the diagnosis process, resulting in serious consequences. Therefore, the development of a detection device that can effectively detect intestinal bleeding and accurately locate the bleeding point is of great significance for improving the medical level and protecting the lives of patients.

Currently, the clinical methods for detecting and locating intestinal bleeding mainly include colonoscopy, radionuclide scanning, angiography, and capsule endoscopy. Colonoscopy is the most widely used method in the examination of gastrointestinal bleeding. Generally, colonoscopy can go deep into the proximal jejunum and the terminal ileum 50 to 80 cm, so as to locate and explore the bleeding focus of the intervening intestinal segment. However, colonoscopy is a highly invasive examination method, and its operation is difficult, and the intervention of colonoscopy during the examination is easy to traumatize the patient and bear the pain caused by the examination. Colonoscopy also increases the complications caused by the examination and increases the mortality rate. Nuclide scans are often used to detect small bowel bleeding. The disadvantage of this method is that it cannot be used for qualitative diagnosis, and it is also difficult to be used for accurate location of bleeding points. Angiography is mostly used for patients with active bleeding and a large amount of bleeding, but it is not effective for patients with slow bleeding and a small amount of bleeding.

Capsule endoscopy is an emerging method for the detection of small intestinal bleeding. Since Israel's Given Imaging Ltd launched the digestive tract visualization capsule endoscope Pillcam, capsule endoscopy has attracted people's attention because it is completely non-invasive. After Pillcam, Japan's RF System Lab and OLYMPUS launched the Norika series and Endocapsule series of capsule endoscope products respectively. The OMOM capsule endoscope of China Jinshan Company has also been widely used in clinical practice. Scholars from South Korea, Germany, Italy and Belgium have also proposed technical assumptions about capsule endoscopy. Capsule endoscopy is also insufficient for the examination of gastrointestinal bleeding, and its effect on the inspection of gastrointestinal folds and bends is not good. In addition, capsule endoscopy is to transmit images outside the body, requiring doctors to read a large number of images and judge intestinal bleeding based on experience, resulting in a very heavy workload for doctors. Even if symptoms of intestinal bleeding are found, doctors cannot get the specific location of the bleeding area based on the image alone, so they can carry out targeted treatment.

In Chinese patent CN200710045625.X, a device for detecting gastrointestinal bleeding using a hemoglobin sensor is disclosed. The device includes a micro-hemoglobin detection device with a built-in hemoglobin sensor, a bleeding point location device, a record storage device, and a gastrointestinal diagnosis and analysis system. The hemoglobin detection device enters the gastrointestinal tract from the oral cavity, and moves in the gastrointestinal tract by means of the physiological peristalsis of the gastrointestinal tract. The hemoglobin sensor can detect the concentration of hemoglobin in the gastrointestinal tract and send the data to the outside of the body. The bleeding point positioning device calculates the position of the micro-hemoglobin detection device in the body by detecting the magnetic field generated by the permanent magnet in the micro-hemoglobin detection device in the bleeding point positioning device, and the corresponding relationship between the experimental detection data and the intestinal segment. The record storage device is used for wirelessly receiving and storing the detection data emitted by the micro-hemoglobin detection device. The gastrointestinal diagnosis and analysis system is used to read and process the data in the record storage device to obtain the gastrointestinal bleeding status.

The above invention has the following disadvantages: the hemoglobin sensor used in the miniature hemoglobin detection device described in this invention needs to contact the sensor electrodes with the contents of the gastrointestinal tract, and the contents of the gastrointestinal tract will contaminate the sensor electrodes, making the sensor detection results unstable.
