Problems solved by technology

This method is cumbersome, each test tube system must be sealed and then blasted
In particular, the general balloon is highly elastic. Even if it is inflated a lot, the pressure of the balloon and the balloon tube system can only rise to more than ten centimeters of water column, which cannot reach the required range of pressure responsiveness detection of the balloon tube system.

Embodiment Construction

[0007] Uncover the container cover 6, put a diaphragm function testing tube with double airbags (one airbag is used to detect esophageal pressure, and the other airbag is used to detect gastric pressure) into the container 7, and connect the joint 9 communicating with the esophageal bag to a small hole 1, connect the joint 10 communicating with the gastric bag to the inner end of the small hole 2, connect the bladder tube connector 8 to the inner end of the small hole 3, and then cover the container cap 6. The outer ends of the small holes 1, 2 and 3 are respectively connected with pressure sensors. Through the large hole 4 connected to the air pump on the wall of the airtight container, inject gas and pressurize until 100cmH2O, the disc on the deflation valve 5 suddenly opens, and at this time, a curve of pressure rising and then suddenly falling can be recorded. If the three pressure signal lines can coincide, it is qualified, otherwise, it is unqualified. On the basis of t...

Abstract

The invention relates to a pressure reactivity detection device of double-balloon catheters. The pressure reactivity detection device comprises a sealed container which can be opened, wherein the wall of the container is provided with three or more small holes communicated with the inside and outside of the container. The pressure reactivity detection device further comprises an air inlet pressing port and a deflation valve which are used for detecting pressure reactivity of the double-balloon catheters. The pressure reactivity detection device is used for detecting pressure reactivity of one or more double-balloon catheters, and the pressure reactivity detection device can be used for detecting quality of the double-balloon catheters like diaphragm function detection tubes by replacing a traditional balloon blasting method.

Description

(1) Technical field [0001] The invention relates to a pressure responsive detection device with a double balloon catheter, especially a diaphragm function detection tube. (2) Background technology [0002] There are two lumens in the diaphragm function testing tube, which are respectively connected to two air bags placed in the stomach and esophagus to sense the pressure. The indicator reflecting diaphragm function is transdiaphragmatic pressure, which is the difference between gastric pressure and esophageal pressure. To accurately reflect the function of the diaphragm, it is first necessary to ensure that the two airbags used have good and consistent pressure responsiveness and the patency of the lumen. Because the gastric pouch of the diaphragm function test catheter is located under the esophageal electrode, the esophageal electrode may compress the lumen connected to the gastric pouch, resulting in poor pressure response. For a long time, the pressure responsiveness o...
