Description

Fixed gastric bleeding monitoring capsule endoscope and gastric bleeding real-time monitoring system

technical field

The utility model belongs to the technical field of gastroenterology medical instruments, in particular to a fixable gastric bleeding monitoring capsule endoscope and a gastric bleeding real-time monitoring system suitable for real-time monitoring of gastric bleeding.

Background technique

Acute upper gastrointestinal bleeding refers to bleeding caused by diseases of the gastrointestinal tract above the ligament of Trevor. It is a common emergency in clinical practice with high mortality. The most common site of upper gastrointestinal bleeding is the stomach, accounting for more than 60% of the entire upper gastrointestinal bleeding. The most common bleeding lesions are peptic ulcer, gastric cancer, stress ulcer, and portal hypertensive gastropathy. The common clinical manifestations of patients with acute upper gastrointestinal bleeding are hematemesis, melena symptoms, dizziness, pale complexion, increased heart rate, and decreased blood pressure and other signs of peripheral circulatory failure.

For the diagnosis of the cause of gastric bleeding, gastroscope is the most critical examination, which can detect the mucosa of the upper gastrointestinal tract in time, and at the same time, the lesions can be treated with drug spray injection, thermal coagulation therapy and hemostatic clips in a timely manner. However, a considerable number of patients are at risk of rebleeding after receiving endoscopic hemostasis. At the same time, gastroscopy is an invasive and invasive operation, and the patient feels very uncomfortable during the examination. Therefore, after the cause is identified and the endoscopic treatment is completed, the endoscopy is withdrawn, and the situation of gastric lesions cannot be monitored in real time. Clinicians often judge the amount of bleeding and the bleeding situation of patients through the clinical manifestations such as hematemesis and blood in the stool, as well as the hemoglobin concentration and red blood cell count in routine blood tests.

Capsule endoscopy, the full name of "smart capsule digestive tract endoscopy system", is a capsule-shaped endoscope with a built-in camera and signal transmission device. And take images, the doctor uses the in vitro image recorder and imaging workstation to understand the entire digestive tract of the subject, so as to make a diagnosis of his condition. Capsule endoscopy has the advantages of small size, non-invasive, single-use, and no cross-infection. Capsule endoscopy currently used in clinical applications is divided into esophageal capsule endoscopy, small bowel capsule endoscopy, magnetically controlled capsule gastroscope, colon capsule endoscopy, etc. According to the different settings of capsule endoscopy functions, capsules with different functions such as monitoring gastrointestinal pressure, pH value, and power capsules are derived. However, there is no capsule endoscope that can be fixed in a specific position in the stomach for real-time monitoring of gastric lesions.

In patients with acute gastric hemorrhage, the rebleeding rate within 3 days is still high under the condition of active endoscopic treatment. Once rebleeding occurs, the risk of death increases rapidly. However, only relying on the patient's clinical manifestations and hemoglobin indicators to judge the amount of bleeding often has a certain delay, and it is impossible to implement rescue in the first time, and it is impossible to find out the specific bleeding situation in the patient's stomach and the healing of the lesions. At present, there is still a lack of a device and technology that can monitor the situation in the stomach in real time, so that the clinician can be reminded and alarmed of the situation of gastric bleeding in time.
