Real-time pressure monitoring system and method for air bag of artificial airway

Abstract

The invention belongs to the technical field of pressure monitoring of medical equipment and particularly relates to a real-time pressure monitoring system for an air bag of an artificial airway. Thesystem comprises a controller, a pressure induction module, a pressure control module, a data storage module, a data transmission module, a display module and a warning module. The invention further provides a real-time pressure monitoring method for the air bag of the artificial airway. After pressure of the air bag of the artificial airway is induced through the pressure induction module, the pressure control module is controlled to regulate and control the pressure of the air bag of the artificial airway by the controller, data are displayed by the display module, are stored by the data storage module and can be transmitted to an upper computer by the data transmission module, and the warning module performs warning timely in case of abnormal conditions, so that changing of the pressureof the air bag can be monitored in real time, and circumstances possibly causing harm are warned timely; and data of a patient are conveniently stored in real time and are purposely transmitted to acomputer of a doctor, so that later-stage analysis and research by the doctor are facilitated.

Description

technical field [0001] The invention belongs to the technical field of pressure monitoring of medical equipment, and in particular relates to a real-time pressure monitoring system and method for an air bag of an artificial airway. Background technique [0002] In clinical practice, patients need to establish an artificial airway to maintain their normal breathing movement due to their serious illness. One type of catheter with an inflatable balloon is often used to create an artificial airway. This type of catheter with an inflatable balloon needs to inflate and deflate the balloon, and the pressure in the balloon needs to be controlled, and in most cases it is maintained at 25-30cmH 2 O. Currently clinically, the medical personnel monitor and adjust the air bag pressure every 2-4 hours by using the air bag pressure gauge. However, the air bag pressure is out of range most of the time within 2-4 hours because of air leakage of the air bag itself, patient cough or body po...

Problems solved by technology

[0003] Aiming at the deficiencies of the above-mentioned prior art, the present invention provides a real-time pressure monitoring system and method for the air bag of the artificial airway, the purpose of which is to solve the problem of air bag pressure leakage caused by the air bag itself of the existing artificial airway, the cough of the patient or the change of the body position. The airbag pressure is out of range for most of the time within 2-4 hours; when the airbag pressure is insufficient, it will cause aspiration of the patient and increase the infection rate of pneumonia; Technical aspects of the phenomenon of capillary injury
