Abstract
The utility model discloses a wireless system for monitoring esophagus pH values. The wireless system comprises a pH capsule and a data recorder, wherein, the pH capsule transmits the data to the data recorder on the basis of the radio-frequency technology; the wireless system is characterized in that the pH capsule has a flat streamlined capsule-shaped structure, and at least a hanging end consisting of a stay guy passing through a perforation and a ring is arranged at one end in the long axis direction of an outer casing of the pH capsule; the sensor part of a pH sensor arranged in the pH capsule is exposed outside the capsule outer casing and arranged at the other end of the pH capsule; and the pH capsule can naturally fall off, enter the digestive tract and be discharged out of the body after the test is finished. The utility model has the following advantages: the wireless system can be operated in a visual state, thereby ensuring the precise positioning; the fixing effect of the pH capsule can be controlled on a real-time basis, thereby avoiding the risk that the pH capsule enters the trachea by mistake, improving the tolerance of a patient and realizing the long-time monitoring of the esophagus PH value. The wireless system has a wide application prospect in the aspect of the diagnosis of esophagus reflux diseases and relevant esophagus diseases.
Description
Technical field
This utility model relates to medical apparatus and instruments, and the monitoring device of pH value in particularly a kind of esophagus specifically is an acid-base value wireless monitor system in a kind of esophagus.
Background technology
Gastroesophageal reflux disease (GERD) is meant stomach or the anti-esophagus that flows to of duodenum content, causes multiple complications, has damaged patient's quality of life.Modal clinical symptoms is heartburn, retrosternal pain and acid regurgitation.The outer symptom of esophagus also can appear in serious gastroesophageal reflux patient, shows as chronic pharyngitis, hoarseness, tracheitis, asthma etc., and constant error is examined and is bronchitis, pneumonia or asthma clinically.24 Hours PH Monitoring are " goldstandards " of diagnosis GERD acid reflux disease in the esophagus, and it can clearly reveal the relation of anti-stream outbreak and symptom, also can distinguish the gastroesophageal reflux that different positions take place and distinguish the factor that influences gastroesophageal reflux.
Traditional catheter type pH monitoring system comprises a conduit, and the doctor need pass patient's nasal cavity with this root conduit and enter esophagus, and directly is connected with recording system.During use, need elder generation that conduit is inserted to gastric, monitor shows acid ph value, and expression pH probe has entered gastric, and slowly outside then tractive pH conduit makes pH electrode place sphincter LES upper end 5cm place under the esophagus, has certain site error.Another localization method is: the LES position is determined in should go ahead of the rest before detection esophageal manometry or gastroscopy, and then the length of definite conduit, and like this, the patient just need carry out extra misery, and doctor's operation is also complicated more.In 24 hours checking processes, because the existence of conduit, very painful and embarrassed, Most patients need be stayed at home, and fasting also keeps sitting posture for a long time, can not normally have a bath and sleep.Because the target of test is the anti-stream situation of monitoring patient in the normal activity process, like this, certainly will influence the accuracy of test.In view of traditional catheter type pH monitoring system complicated operation, patient tolerability poor, reusable catheter type probe can cause measuring inaccurate, cross infection equivalent risk, this type of inspection is reluctant to carry out by considerable hospital, and the patient suffers sing misdiagnosis and mistreatment for a long time, has a strong impact on physical and mental health.
At present, a kind of pH value of esophagus wireless monitor system that is used for is arranged on the market, this system comprises pH capsule, data logger, analysis software and fixture, overcome above-mentioned shortcoming to a certain extent, it is by being fixed in the pH capsule on the esophageal wall by " safety pin " fixed form, the pH data that record are transferred on the receptor between patient's waist with wireless mode, thereby the duct free electrode is kept somewhere.
But this system still has a lot of deficiencies, such as: the capsular positioning accuracy of pH is not high, and fixed mass can not be understood in real time, data recorder function redundancy, cost height, and complicated operation, patient's toleration is not high or the like; At first, the location technology more complicated of this scheme, the LES position is determined in should go ahead of the rest before detection esophageal manometry or gastroscopy, and then the length of definite conduit, like this, the capsular positioning accuracy of pH is limited by other measurement results, needs of patients bears extra misery, doctor's complicated operation.Secondly, the doctor will be equipped with the capsular fixture per os of pH and be probeed in the process of esophagus, because can't careful observation esophagus details, the danger that trachea takes place to insert easily requires very high to doctor's operation skill.Once more, fixed effect can't be understood in real time, the pH capsule adopts the method for vacuum suction, puncture immobile mucosa to fix, operating procedure is many, fixed effect also can't be understood in real time, and having comes off causes the risk of test crash, still needs carry out extra operation with gastroscope, so that the inspection fixed effect, ease of use is poor.
Summary of the invention
At the deficiencies in the prior art, the purpose of this utility model be to provide a kind of easy to operate, the location accurately and not need special positioner, can reduce the novel pH value of esophagus wireless monitor system of patient's misery.
The technical scheme that adopts is so for achieving the above object: promptly a kind of pH value of esophagus wireless monitor system, comprise pH capsule and data logger two partly, and the pH capsule is by radio-frequency technique and the transmission of data logger data; It is characterized in that:
Described pH capsule is fairshaped flat capsule shape structure, and the axial end of its shell major axis has at least one perforation, is installed with backguy and annulus in the perforation and constitutes the capsular end that hangs from above of pH; The transducing part of the pH pick off of configuration is exposed to the outside of capsule shell in the described pH capsule, is positioned at the pH capsule other end and constitutes the test side.
Described capsule shell is by nontoxic, harmless to human body and have acid-alkali-corrosive-resisting, and the medical macromolecular materials with hydrophobic property are made.Described annulus is made by the medical metal material of and acid-alkali-corrosive-resisting nontoxic, harmless to human body.Described backguy is by the biomaterial for medical purpose of nontoxic, the harmless automatic degraded of human body being made, being had hydrophobic property.
The use work process of system described in the utility model is such: promptly under the involving of backguy, patient's pH capsule of swallowing naturally, utilize gastroscope and related accessories, the pH capsule is fixed on the mucosa at 5cm place, esophagus LES top, fixedly finish, withdraw from backguy, because the sensing head of the pH pick off on the pH capsule is downward, pH value in can the long term monitoring esophagus utilizes radio-frequency technique that data are sent to external data logger.After test was finished, the pH capsule came off naturally from esophagus, entered digestive tract and excreted.The present invention is owing to can directly adopt existing visualized operation device in the installation course, the location is accurate, and the capsular fixed effect of pH can be grasped in real time, avoids the pH capsule to be strayed into the risk of trachea, patient's toleration improves, and can realize the long-time monitoring to pH value of esophagus.
Obviously, this utility model compared with prior art has safety and the localized accuracy controlled, and designs simplification, can reduce the expense that the patient bears.
