Positioning casing tube of PH monitoring tube and bile acid monitoring tube imbedded into oesophagus

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 [0001] The invention relates to the technical field of medical devices, and relates to a positioning sleeve used for placing esophageal pH monitoring catheters and bile acid monitoring catheters. Background technique [0002] Clinically, for patients with acid-related diseases such as reflux esophagitis, it is necessary to monitor the pH and bile acids in the esophagus for 24 hours to determine the total time of reflux, the frequency of reflux, and the duration of reflux when the pH in the esophagus is less than 4 , and the relationship between reflux and body position, meals, and pain. Currently, perfusion catheters are used in clinical pH monitoring and bile acid monitoring, and the head of the catheter is a monitoring electrode. For insertion, the catheter is inserted nasally until the catheter tip is placed 5 cm above the esophagus-gastric junction. This positioning is crucial, and it is directly related to the value of the test, which is also related t...

Problems solved by technology

On the one hand, this operation is cumbersome and time-consuming, which is not conducive to rapid diagnosis. On the other hand, this positioning is also estimated and not exact, which makes the measured values ​​​​comparable between batches poor.

Moreover, when two catheters are inserted simultaneously or successively, mutual entanglement often occurs, which also brings great trouble to the operator.
