Compared with the prior art, with the adoption of the utility model, a person to be detected has no pain or no uncomfortable reaction, can carry with portable external receptor conveniently and can move freely when being detected so as to ensure that the wave of gastrointestinal motility under completely physiological status is recorded.
Description
Technical field
This utility model relates to medical instruments field, specifically is the wireless record device that a kind of human intestines and stomach's of being used for power detects.
Background technology
Gastrointestinal motility is one of most important physiological function of digestive system, and its process is opened and closed by the contraction clocklike of digestive tract tube wall smooth muscle and diastole and sphincteral harmony and finishes, and a lot of disease associations of gastrointestinal motility and human body are necessary its further investigation.Measure pharynx and esophageal contractions motion from usefulness air bag methods such as Kronecker in 1883, the development in year surplus the process nearly 100, people are unclear fully yet for the gastrointestinal motility rule of animal, especially human body at present, studying carefully its main cause is a lot of shortcomings of research method existence of record gastrointestinal motility, demands urgently improving.
In the prior art, gastrointestinal motility detection method commonly used mainly comprises:
(1) radiological examination: perspective is observed X-ray opaque label or radiosiotope down at the gastrointestinal situation of movement, reflects the gastrointestinal wriggling with this.Shortcoming is character and the variation that only can with the naked eye write down gastrointestinal peristalsis, can not quantize; And detected human or animal will be subjected to the X-ray radiation;
(2) manometry: observe pressure curve at gastrointestinal tract setting pressure foil gauge (extroluminal strain gange) and change.Present existing pertinent instruments domestic market has " HU-809 type transducer for stomach-intestine moving " to reach " KH-100 type gastrointestinal peristalsis dynamic sensor " two kinds, the two all is that phosphor bronze thin slice transducer is sewn on stomach or the duodenal wall with the operation silk thread, the size of transducer has 15X6mm, 10X5mm, 8X4mm, four kinds of models of 3X4mm, can select wherein a kind of as required, draw two leads from semiconductor gauge and be connected to external two road physiology monitors, balance recorder and multimedia bio signal acquisition system etc., input voltage is 0-6VDC, writes down the gastrointestinal peristalsis situation with this.
But the fatal shortcoming of this instrument is: 1, need abdominal that transducer is sewn on the intestinal wall, wound is big, therefore can not be used for the wriggle record of situation of human intestines and stomach; Even 2 in toy, because gastrointestinal wall as thin as a wafer, heeling-in elastic strain sheet almost is difficult to realize; 3, suture has damage to intestinal wall, so the gastrointestinal peristalsis situation of record is not the pattern under the complete physiological status, to a certain degree influences testing result; 4, need the external record of lead connector, in zoopery, the result who is write down need carry out to a certain degree constraint to animal, otherwise animal stings easily or pulls apart the connection lead bad, so can not reflect the gastrointestinal motility pattern under the animal normal physiological state fully.
(3) inner voltage detecting method: some researcheres adopt leads perfusion cannula more and observes the motion of gastrointestinal each several part simultaneously, and shortcoming but small pressure is changed insensitive is difficult to accurately reflect the gastrointestinal peristalsis situation.
(4) electromyogram synchronous detecting: be to be the mode of index research gastrointestinal motility rule with the electrical activity.Because the contraction of gastrointestinal smooth muscle has the spike dependency, so gastrointestinal myoelectrical activity and mechanical movement should have corresponding relation.The instrument that carries out the gastrointestinal motility record by this technological means has the EGEG-8D type eight of Hefei Huake Electron Technique Research Academy's development to lead intelligent gastrointestinal electrographic instrument, and this machine is gain the national patent also, the patent No.: ZL00219931.9.But its maximum shortcoming is the myoelectric waveform that is write down to be easy to be disturbed, and breathing, cough and extraneous slight interference all can influence data analysis.
In addition, Chinese patent 200710044901.0 discloses a kind of " electromagnetic gastroenteritic power function woundless diagnosis system ".Though this patented technology has solved measured's no pain, does not have wound, need not testing conditions restrictions such as bowel relieving and fasting, can reflect the pass through process of normal physiological state monitoring in following 24 hours gastrointestinal content in gastrointestinal tract in the human body intestinal canal substantially.But because it is external uncontrollable, so can not selectively carry out the detection of keypoint part or target site to the measured.
