Description
Technical field
What the present invention relates to is a kind of detection system of technical field of medical instruments, particularly be a kind of electromagnetism tracking mode all-digestive tract physiologic information noinvasive detection system.
Background technology
The quickening of people's rhythm of life and the change of dietary structure; Cause the sickness rate of digestive tract disease to raise day by day; According to statistics; The digestive system disease total incidence accounts for 30% of population, has 1/2 to be the disease of digestive system among the various big hospital outpatient, wherein must the emergency treatment person of being hospitalized for treatment account for emergency treatment inpatient's 25%; Worldwide, because of the dead number of digestive system disease, account for 14% of total death toll.Because medical circle is not understood for the unknown of healthy subjects all-digestive tract intracavity physiological parameter numerical value and to what each physiological parameter of all-digestive tract intracavity under the physiological status changed at present, therefore lacks the objective indicator to the digestive tract disease diagnosis.
Fiber or video image dendoscope can be made diagnosis basically for upper digestive tract and large intestine pathological changes, but the small intestinal pathological changes is Endoscopic " ultimate obstacle ".Although the application of push-type small-bowel endoscope; Can spy on jejunum and have or not pathological changes; But operation is difficulty very; The small intestinal pathological changes at farther position can't be diagnosed, and patient is extremely uncomfortable, causes many complication: pharyngeal scratch, esophagus and cardia mucosa lacerated wound, mandibular joint dislocation, submaxillary gland swelling, anesthetics allergy, facial area subcutaneous hemorrhage, acute gastric dilatation, gastrointestinal perforation and hemorrhage, aspiration pneumonitis even sudden death etc.Therefore, this technology is difficult to accepted.Sonde-type enteroscope can be checked jejunum and ileum top, but the operating time is long, there is the blind area in observation.Intestinal band induced small intestinal mirror can be observed whole small intestinals, but prepare complicacy before the art, length consuming time, less patient suffering is big.Small intestinal is low when opening double contrast radiograph intubate patient suffering, review time be long, will contact more X ray.
Through being retrieved, prior art finds following correlation technique document:
1, patent publication No.: CN1342440, patent name: human body all-digestive tract insertion-type intelligent miniaturized dignosis system, this technology can be under the condition of people's orthobiosis and work, and noinvasive is got involved human body intestinal canal and is checked.Its data of surveying are stored in the inside chip of " the oral part of capsule shape "; Need after " the oral part of capsule shape " excretes, reclaim and dissection " the oral part of capsule shape ", and sense data is carried out date processing from " inside chip "; Therefore; This scheme lacks real-time, in case " the oral part of capsule shape " owing to collecting improper losing, then can make the whole test failure because of free of data.
2, patent publication No.: CN1401393; Patent name: all-digestive tract microcapsule non-invasive introduced diagnostic and examination system; The data that this technology detects " the oral part of capsule shape " through wireless mode are sent to external through wireless mode, solved the real-time problem of testing process, and when " the oral part of capsule shape " during owing to improper the losing of collection; Detect data and also can not lose, but this system can only detect the gastrointestinal tract pressure and temperature.Clinical practice shows; GERD, functional dyspepsia, intestinal pseudo obstruction, irritable bowel syndrome, ruminate syndrome; Functional dysphagia, the formation mechanism of digestive tract disease such as NCCP, aerophagia, functional vomiting, functional distension gas and diagnosis index are mainly according to PH in the gastrointestinal tract and Changing Pattern thereof.Though digestive tract disease such as syndrome and digestive tract internal pressure at the bottom of functional constipation, diarrhoea, functional abdominal pain syndrome, functional encopresis, functional anal orifice and rectal intestine pain, the basin, temperature are relevant, have some relations with PH and variation thereof in the digestive tract.Therefore, there is open defect in this patent.
Though above-mentioned two patents have solved the noinvasive no pain of all-digestive tract part physiological parameter and have detected problem; But can not obtain to detect the corresponding relation of data and digestive tract to be detected position; That is to say, both be to have found the unusual and disease in the all-digestive tract, owing to there is not the position relation of focus; So still can not solve the accurate diagnosis and the specific aim treatment problem of all-digestive tract disease, limit its clinical practice using value.
3, applicant's patent in one's early years; Patent publication No.: CN 1620985; Patent name: the external electromagnetism excitation-type of all-digestive tract swallowing type radio pill navigation system; This technology comprises three-axle magnetic field pick off, signal processing module and the wireless communication module that is sealed in the capsule, the vitro data monitor that external three magnetostatic fields excite loop coil and are made up of single chip machine controlling circuit, constant-current source circuit, variable connector, wireless communication module, memorizer, power module.During system works; Three loop coils are fixed on body surface and provide exciting curent to produce magnetic field successively by data logger; Three-axle magnetic field pick off in the body in the capsule detects the magnetic induction value of three coils successively; Convert digital signal to and, receive and be saved in memorizer by signal processing circuit by the vitro data monitor through the wireless communication module emission.After capsule quits work, obtain capsular position constantly according to each three corresponding constantly field intensity value, and it is intravital through process and through the time the people to obtain capsule thus, and then obtains capsule three-dimensional track in vivo by computer.But this system only provides the position relation of " capsule ", can not detect the information such as physiological parameter that characterize digestive tract physiological function and pathological characters, can not realize the non-invasive diagnosis to the human consumption tract disease.
4, applicant's patent in one's early years; Patent publication No.: CN1401393, patent name: all-digestive tract microcapsule non-invasive introduced diagnostic and examination system, this technology profile is a capsule shape; The latex thin film compatible with inside of human body is covered in the outer surface of whole system frame; The micro pressure sensor of arranging on the frame, micro temperature sensor link to each other with A/D converter through signal amplifier respectively, and A/D converter is connected with the dedicated microprocessor chip, and the dedicated microprocessor chip links to each other with the signal wireless transport function; By transmitting antenna with detectable signal to external emission, system is supplied power by minicell.External receiving system receives above-mentioned signal and stores, and carries out in real time or postmortem analysis the output result as required.Because the restriction on system structure and the function; This patent only can human body digestive tract intracavity the pressure and temperature value; Can not obtain to detect the corresponding relation of data and intestinal segment to be detected, that is to say it both is abnormal data to have occurred, can't confirm that also this is unusually at gastral particular location; Owing to be not sure of lesions position, thereby seriously restricted the application of this system in clinical diagnosis and disease treatment.
Therefore, through to existing patent and public technology retrieval, there is not to find to detect simultaneously the Medical Instruments of all-digestive tract physiological parameter and parameter position to be detected information; There is complicated operating process in the testing process of existing simultaneously digestive tract disease checkout gear, shortcoming such as wound is arranged, and existing diagnostic method can't satisfy the clinical practice application demand.
