Abstract
The invention relates to the technical field of medical apparatus, which is positioning casing internally configured with an oesophaus PH monitoring and a bile acids monitoring canal. The positioning casing is composed of a canal (1) and an air cell (2); wherein, the canal (1) is composed of an air transmitting tube (11) and an electrode canal (12); the air transmitting tube (11) is connected with the air cell with top end; the air cell (2) has a sub-cell body (21) and a cell neck (22); the cell neck (22) is communicated with the air transmitting tube (11). Aftewr charged with air, the cell body (21) is in hollow sphere shape with the diameter larger than the inner diameter of the oesophagus and the cell neck (22) is in hollow column shape with the outer diameter smaller than the inner diameter of the oesophagus with the column is in 5 cm length; the electrode canal (12) is thick and is positioned at one side of the air transmitting pipe (11); an open is opened at top end. When in use, inserting the two canals into the electrode canal and then into stomach normally by passing nasal cavity; after charging air into the cell cavity, pulling back slightly the canals and enabling the cell neck enter into the oesophagus until being clamped by the cell body, thus can position the canal. The invention has the advantages of simple structure, convenient utilization, precious positioning and time-saving, which is favorable for quick diagnose and improving the precision for inspection.
Description
Technical field
The present invention relates to technical field of medical instruments, is a kind of locating sleeve that is used to insert esophageal pH monitoring conduit and bile acid monitoring conduit.
Background technology
Clinically, to acid-related disease patients such as reflux esophagitiss, need carry out monitoring in 24 hours Endo-esophageal pH and bile acid, with anti-stream total time of measuring pH＜4 in the esophagus, anti-number of times, the anti-relations such as persistent period and anti-stream and position, dining, pain that flow of flowing.PH monitoring and bile acid monitoring all adopt the filling type conduit clinically at present, and the head of conduit is the monitoring electrode.When inserting, conduit is inserted from nasal cavity, until catheter head being placed 5cm place, esophagus and stomach intersection top.This location is vital, is directly connected to the numerical value of detection, also just is related to the diagnosis of disease and the judgement of curative effect.Though scale is arranged on the catheter wall, because individual variation also must could be located by means of X line perspective or to the detection repeatedly of harmonization of the stomach esophagogastric junction place pH value when inserting.If by means of X line perspective, person under inspection and medical personnel can be subjected to x-ray radiation; If adopt the testing result of pH value to judge, the head with conduit inserts gastric so earlier, and stomach inner pH value is lower, and pH is 2-4, and then with catheter pullback to esophagus, pH value is 7-8 in the esophagus, detects so repeatedly, locatees behind the contrast pH value.On the one hand this complex operation is time-consuming, is unfavorable for quick diagnosis, and this on the other hand location also estimates, and imprecise, between making batch to survey the numerical value comparability poor.Moreover two conduits tend to occur mutual wrapping phenomena simultaneously or when successively inserting, and also bring very big trouble to the operator.
Summary of the invention
Easy to operate when the purpose of this invention is to provide a kind of inserting, the esophageal pH monitoring conduit of accurate positioning and the locating sleeve of bile acid monitoring conduit.
The present invention is made up of conduit and air bag, conduit is made up of appendix and electrode catheter, the appendix top links to each other with air bag, air bag divides utricule and capsule neck two parts, the capsule neck communicates with appendix, when inflating by appendix, the utricule of air bag is hollow ball-shape, and diameter is greater than the internal diameter of esophagus, the capsule neck is hollow cylindrical, external diameter is little than the esophagus internal diameter, column length 5cm, and electrode catheter is thicker, can hold esophageal pH monitoring conduit and/or bile acid monitoring conduit, it is positioned at a side of appendix, a middle shared tube wall, the top end opening of electrode catheter.Opening part and capsule neck end face keep certain distance, so that catheter head is exposed.During use, drain the gas in the air bag, esophageal pH monitoring conduit and bile acid monitoring conduit are inserted the opening part of the tail end of electrode catheter, push ahead until stretching out the top and capsule neck end face is collided, airbag wall is placed in the head of two conduits, routinely the head of conduit is inserted gastric by nasal cavity again, this moment by appendix to airbag aeration, it is full gradually that air bag promptly breaks away from catheter head, then conduit is pulled back gently, the capsule neck enters esophagus until being blocked by utricule, can locate, and the head of two monitoring tubes just is positioned stomach and top, esophagogastric junction place 5cm.Gas in the air bag is discharged the back just can monitor routinely.
The present invention is simple in structure, and is easy to use, and accurate positioning saves time, disposable use is safe and reliable, and solved two conduits simultaneously or the mutual winding problem that may occur when successively inserting, and helps quick diagnosis and improves the accuracy rate that detects.The present invention also can be used for the assist location of pH monitoring tube and bile acid monitoring conduit separately.
