Dimesize non-traumatic monitoring system of pressure and temperature for internal envirnoment or bronchia

Abstract

A miniature pressure and temp monitoring system for the internal environment of bronchus is composed of a trachea catheter, a miniature pressure and temp monitor consisting of miniature pressure probe and miniature temp probe, which are embedded in the wall of catheter and have surficial film on their front ends, a data acquisition device, a data processing device, and the electrically conductive lines in the wall of said catheter.

Description

Technical field: [0001] The invention relates to medical equipment, in particular to a medical monitoring device, in particular to a temperature and pressure sensing device in an airway, in particular to a miniature non-invasive pressure and temperature monitoring system for an environment in a bronchi. Background technique: [0002] In the prior art, monitoring the continuous changes of temperature and pressure in the airway is of great significance for the accurate grasp of pathophysiological processes and the adjustment of respiratory parameters. Among them, the body temperature monitoring device currently has electronic thermometers, infrared temperature sensors and liquid crystal thermometers in clinical applications. Electronic thermometers, infrared temperature sensors and liquid crystal thermometers are used to measure human nasopharynx, distal esophagus, bladder and rectum, The temperature of the heart, jugular vein, tympanic membrane, forehead and neck skin, usuall...

AI Technical Summary

Problems solved by technology

However, there is currently no temperature monitoring device that can directly measure the local airway temperature and its dynamic changes.

In addition, the monitoring of respiratory mechanics can reflect the elastic characteristics and flow resistance characteristics of the chest and lungs, and is of great help in observing the evolution of respiratory system resistance and the diagnosis and treatment of lung parenchymal diseases. Inside the machine, it is connected to the patient through a very long threaded tube and endotracheal tube, so the monitored pressure is not the original pressure change in the patient's airway, but the pressure measured after being buffered by a long pipeline. However, there is still a large error with the original pressure measured in the airway, which seriously affects the accurate judgment of respiratory mechanical parameters and the reasonable adjustment of respiratory parameters.
