Total digestive tract emptying non-invasive examination system and treatment method of examination results

Abstract

The invention provides a total digestive tract emptying non-invasive examination system which can be used for continuous non-invasive examination of the total digestive tract emptying process. The system comprises a gastrointestinal tract micro detection capsule, an in vitro control device, a magnetic field sensor array and a data treatment workstation. The invention also provides a corresponding treatment method of examination results of the system. Compared with the prior art, the system and the method have the following advantages: 1. without the help of any reagent, total digestive tract emptying can be detected in the natural physiological status, without causing pains or injuries to human bodies; 2. the detection results are intuitive and accurate, the detected information is abundant and comprehensive, and such information as the three-dimensional emptying paths of the contents in the total digestive tract and the emptying time and speed and peristalsis frequency of each intestine segment can be obtained; and 3. the system is convenient to use and is lower in cost.

Description

technical field [0001] The present invention relates to a system for non-invasive examination of total digestive tract emptying and a processing method for examination results, in particular to a painless and trauma-free detection of food excretion in the entire digestive tract under the natural physiological state of non-colon cleansing and fasting. An intelligent detection system for an empty process belongs to the technical field of medical equipment. Background technique [0002] Motor function is one of the most important physiological functions of the digestive system and is the basis for food digestion and absorption. Insufficient gastrointestinal motility will lead to delayed gastric emptying and slow intestinal transit; excessive gastrointestinal motility will lead to rapid gastric emptying and rapid intestinal transit. Therefore, gastrointestinal emptying time is an intuitive and important indicator to reflect the level of gastrointestinal motility. Therefore, gas...

Problems solved by technology

However, it is time-consuming and frequently exposed, and it is difficult to be accepted by the subjects, which greatly limits the inspection

Nuclide imaging can accurately detect esophageal transit time, gastric emptying, small intestinal transit time, gastroesophageal reflux, duodenogastric reflux, etc., with good quantification and repeatability, and is the current method for measuring gastrointestinal emptying" "gold standard", but because of the use of nuclides, it is harmful to patients and expensive, and it is not suitable for long-term use, and its application is also limited

The real-time ultrasound method for detecting gastric emptying is safe, reliable, and easy to repeat. Its disadvantage is that it can only be used to detect liquid gastric emptying, and at the same time requires the examiner to be proficient in B-ultrasound examination techniques

Compared with other methods, this method is simple and easy to operate, has no damage to the human body, and can continuously monitor the emptying of the entire digestive tract. It has a good application prospect, but there are still some problems: mainly due to the volume of swallowed magnetic marker Tiny, the magnetic field is weak, and the generated magnetic field strength decays at the ratio of r3 with the increase of distance r, and in order to obtain the attitude and position of the magnetic marker, it is necessary to solve the magnetic field strength and these parameters When there are large measurement errors and environmental interference in the magnetic field strength, it is difficult to accurately track in a large range, especially the attitude error is large

Another drawback is the difficulty in associating the position of the magnetic marker with the specific bowel segment of the subject
