Description
Technical field
The present invention relates to a kind of system of technical field of medical instruments, specifically is a kind of gastrointestinal tract hemorrhage non-invasive monitoring system.
Background technology
Gastrointestinal hemorrhage is the caused export-oriented symptoms of various gastroenteropathys, and the lighter shows as daily having blood in stool, dizziness, cold sweat; Weight person can make the people suffer a shock, even dead.Gastrointestinal tract physiological blood loss is approximately 0.6ml in the normal person 24h, and losing blood that pathological changes causes will be measured much larger than this.Gastrointestinal tract is in case obviously hemorrhage, its diagnosis and treat very urgent.The diverse location gastrointestinal hemorrhage is also different on the symptomatic reaction of human body.Gastrointestinal tract position more than the stomach pylorus is hemorrhage may to cause hematemesis; And small intestinal and colon, hemorrhage of rectum will cause having blood in stool, and be just red etc.But enteric hemorrhage has significantly different again with the knot rectum, the blood that the knot rectum goes out generally can directly be observed in feces, and enteric hemorrhage is owing to fully merge with food, in feces, with the naked eye can't see, but detect the existence that to find wherein to have blood constituent by technological means and test, the proof patient suffers from the disease of gastrointestinal hemorrhage, but because the length of small intestinal is big, bending is many, the structure relative complex, therefore be difficult to understand fully cause of bleeding, can not accurately locate hemorrhagic focus, bring very big difficulty for diagnosis and treatment.If the patient can not get effective treatment because of diagnosing for a long time, anemia appears in the lighter, and weight person is because the deterioration of diseased region such as tumor etc. causes serious consequence.Therefore study the diagnostor of gastrointestinal hemorrhage, particularly can effectively detect enteric hemorrhage, crucial meaning is arranged for improving the health care level.
The medical means and the instrument of procuratorial work gastrointestinal hemorrhage are also a lot of at present, mainly contain: laboratory examination, and the agent of x line barium is checked, endoscopy, selective arteriography, radionuclide scanning, still all there is deficiency separately in capsule endoscopes etc.
Find through literature search prior art, people such as Israel G.Iddan and G.Meron have reported their research work about " Wirelesscapsule endoscopy " (wireless capsule scope) in 2000 on the 417th page at the 405th volume of " Nature " (nature) academic journals, after this also further discuss research work progress and clinical practice situation.Data shows that they are developed into M2A type capsule endoscopic system, and has formed related medical apparatus product.This capsule endoscopic product is made up of cmos image chip and microprocessor, white light-emitting diode, short focal length lens, miniature information transmitter and antenna, overall dimensions is Φ 11mm * 26mm, weigh 3.45 grams, by silver oxide cell as the energy, can be in gastrointestinal tract continuous operation 6～8 hours.Capsule endoscopic can each seconds 2 speed of the width of cloth to external emission image, receive above-mentioned image information and be stored in the portable receiver attached to the aerial array of body surface to treat subsequent treatment.
In the indagation process, capsule endoscopic is obeyed from the oral cavity into entering gastrointestinal tract, and the dynamic orbit smoothing ground of wriggling by myenteron self passes through gastrointestinal tract, and takes gastrointestinal tract inwall image, and the medical worker is by the identification to photographic images, thus the judgement gastroenteropathy.Whole checking process need not inflation, and can have no to obtain under the painful situation photography data of small intestinal the patient, and the diagnosis positive rate of capsule endoscopic is 60%.But this method costs an arm and a leg, and carry out under the condition of bowel relieving, fasting.Tradition endoscopic diagnosis process usually injecting gas struts coat of the stomach, and observing the slight pathological changes of gastric mucosa better, and capsule endoscopic can not reach this requirement.For behind the gastrointestinal tract invaginate wall and knee, be difficult to obtain distinct image, easily hemorrhagic focus is produced omission, and also bad for the observation effect of large-area hemorrhage, exist and detect the blind area, this system can not quantitatively obtain gastrointestinal hemorrhage amount information simultaneously.But because their invasive in testing process even non-invasive have obtained the attention of medical circle, also there are the report of similar research in Japan, China and Korea S.
