Problems solved by technology
The electrogastrogram method is to place electrodes on the abdominal body surface, record the fasting and postprandial gastrointestinal electrical rhythm, and analyze whether there is abnormal gastric electrical rhythm to judge whether the gastrointestinal contraction function is disordered. Although this method is easy to accept, it is clinically difficult. Diagnostic value is controversial
The marker method requires multiple abdominal X-rays taken 24, 48, and 72 hours after the patient swallows the X-ray-opaque marker, which has radiation, expensive equipment, and time-consuming examination

The invention discloses a gastrointestinal motility examination system, comprising: a gastrointestinal motility capsule, a positioning device and a terminal device, the gastrointestinal motility capsule includes a shell and a magnet, and the positioning device includes at least two magnetic sensors i, i∈ (1, N), N is a positive integer greater than or equal to 2; the gastrointestinal power capsule is used to generate a changing magnetic field when the subject moves with the peristalsis of the gastrointestinal tract; the positioning device Magnetic sensor i is used to collect the jth time point T j When the strength data of the magnetic field D ij , and the intensity data D ij Send to the terminal device, j∈(1, N), N is a positive integer greater than or equal to 1; the terminal device is used to ij Determine the position and posture information RPA of the gastrointestinal dynamic capsule in the gastrointestinal tract j And exercise frequency, providing reference information for doctors to make accurate diagnosis and precise treatment. The gastrointestinal motility examination system has the advantages of convenient examination, precise positioning, high efficiency and low cost.
Description
technical field [0001] The invention relates to the technical field of medical devices, in particular to a device and system for examining gastrointestinal motility. Background technique [0002] Digestive system diseases are the second largest medical problem after cardiovascular diseases, and gastrointestinal motility disorders account for nearly half of the digestive tract diseases. Gastrointestinal motility refers to the strength and frequency of gastrointestinal muscle contraction and peristalsis. Gastrointestinal motility disorders can cause indigestion, and mild cases can lead to symptoms such as abdominal distension, constipation, nausea, and vomiting. Over time, it is easy to cause gastritis, gastroparesis, and esophageal reflux Even diseases such as canceration seriously affect the daily work and life of human beings. [0003] At present, the examination methods for evaluating gastrointestinal motility disorders mainly include intracavitary pressure measurement, p...
