Description
Technical Field
The utility model belongs to the field of medical equipment, concretely relates to intestinal power detection device and an intestinal power real-time monitoring system based on thing networking.
Background
Monitoring of gastrointestinal motility is an important item for clinical examination, and particularly, monitoring of intestinal motility of a patient after surgery is an important examination means for guiding clinical treatment of the patient. At present, the gastrointestinal tract motility is clinically carried out by gastrointestinal transmission tests such as an X-ray-opaque marker method, a radionuclide imaging method, a hydrogen breath test and the like. Although the gastrointestinal transmission test is widely used, the gastrointestinal transmission test has a plurality of defects and limitations, and is difficult to be used for patients suffering from gastrointestinal tract function impairment such as postoperative enteroparalysis, which are mainly reflected in that: 1. the examination result only represents the intestinal motility within a period of time and cannot reflect the real-time gastrointestinal motility state. And 2, the inspection equipment is fixed, the requirement on the inspection environment is high, and the bedside operation is difficult to perform. 3. Before examination, contrast medium or imaging material is swallowed, which is not suitable for patients with intestinal obstruction. 4. The inspection cost is high, and the inspection is not suitable for multiple times of inspection. 5. The preparation steps before examination are complicated, and the patient compliance is low.
There are two types of electrical activity of the smooth muscles of the gastrointestinal tract: basic electrical rhythm (slow wave) and action potential (fast wave), and frequency of slow wave is 3-12 times/min. Electrogastrogram (EGG) is an electric signal for recording the electromyographic activity of the stomach and the muscle through an abdominal body surface electrode, can be used as an objective bioelectricity index of the functional activity of the stomach and the intestine, and is mostly used for researching the stomach power and providing objective basis for the curative effect of various treatment methods.
The periodic slow wave of the intestinal tract originates from the interstitial cells of cajal between the longitudinal muscles and the circular muscles of the digestive tract, does not depend on external nerve innervation, is considered as a pacing cell of the movement of the intestinal tract, is also the origin of the contraction starting potential of the smooth muscles of the gastrointestinal tract, and determines the direction, rhythm and speed of the movement of the digestive tract. When the smooth muscle of the digestive tract generates action potential (fast wave), the smooth muscle contracts to generate peristaltic wave to push the intestinal contents, so the fast wave of the intestinal tract is also called intestinal peristaltic wave. At present, an animal test method can monitor the electrical activity of the smooth muscle of the gastrointestinal tract of an animal, see patent document CN102727195A, but the operation is complex, the intestinal tract needs to be migrated to the outside of the body, and the test method causes great trauma to a detected object, so the test method is not suitable for clinical practice.
