Multifunctional respiration signal detecting catheter

Abstract

The invention discloses a multi-functional respiratory signal checking duct that can check respiratory power and diaphragm electric signal and feed nasal simultaneously. It is characterized in that: there are three non interconnected lumens in the duct, which are used for accommodating wire, conducting pressure and feed nasal respectively. The outside of duct is equipped with one saccule, which is connected with one lumen for gullet pressure measurement. The far end of duct is equipped with a plurality of large pores, which are connected with stomach tube joint through large lumen for nasal feeding. The far end of saccule is provided with one earth electrode and nine recording electrode with the length being 1 cm. There is space between electrode and saccule, electrode and far-end large pore, and there is small space between near electrodes. The nine recording electrodes form into five leads. The invention is characterized in that it integrates all functions of traditional stomach tube, oesophgeal pouches, multi-conducting gullet electrode, it can put electrode of duct in the gullet in the gullet correctly and quickly, put the oesophgeal pouches in gullet and far-end of duct in the stomach.

Description

technical field [0001] The invention relates to a multifunctional respiratory signal detection catheter which simultaneously detects respiratory power and diaphragm myoelectric signal and has the function of gastric tube. This catheter can simultaneously measure esophageal pressure and diaphragm muscle electricity and has nasal feeding function. Background technique [0002] Traditionally, tracheal intubation and nasogastric feeding tubes have almost always been placed in patients receiving artificial ventilation in critical care units. If respiratory muscle function is to be tested, it is often necessary to place two more catheters: one is a catheter with a balloon placed in the middle and lower part of the esophagus to measure esophageal pressure; the other is a multiconductor esophageal electrode to detect diaphragm muscle electricity. Since the patient already has a tracheal intubation and a nasal feeding tube, it is difficult or even impossible to insert two catheters ...

AI Technical Summary

Problems solved by technology

Due to the difficulty of placing the detection catheter, it is difficult to monitor the respiratory muscle function in the critically ill unit, resulting in the failure to detect changes in the condition in time, which seriously affects the success rate of resuscitating patients
