Pressure wWireless dynamic pressure monitoring device for artificial trachea cuff

Abstract

The invention discloses a pressure wireless dynamic monitoring device for an artificial trachea cuff. A pressure sensor transmits pressure information to an analog-to-digital converter, the analog-to-digital converter is connected with a microprocessor, the microprocessor is connected with a bedside node wireless communication module, the bedside node wireless communication module is communicated with a network coordinator via a wireless network router, the network coordinator is connected with a nurse station computer, the bedside node wireless communication module takes charge of coordinating wireless communication of the network router and transmits the trachea pressure information and bedside number information data to the nurse station monitoring computer, and the network coordinator further has functions of a gateway. On the one hand, the pressure wireless dynamic monitoring device is communicated with bedside nodes via the network router, and on the other hand, the pressure wireless dynamic monitoring device is connected with the nurse station computer, carries out commands of the computer and responds correspondingly. The pressure wireless dynamic monitoring device is reasonable in structure and fine in work performance.

Description

technical field [0001] The invention relates to a wireless dynamic monitoring device for artificial airway cuff pressure. Background technique [0002] Artificial airway is a connection established between the physiological airway and other air sources. It is one of the common rescue measures for critically ill patients in the ICU. The purpose is to keep the patient's airway unobstructed, remove respiratory secretions and perform mechanical ventilation. Patients with an artificial airway are usually intubated through the mouth or a cannula is placed through a tracheostomy. There is an air bag on the outer wall of the front end of the endotracheal tube or endotracheal tube, which can be inflated after inflation to seal the airway, prevent air leakage and avoid aspiration of oropharyngeal secretions. [0003] With the continuous improvement of the histocompatibility of the endotracheal tube used to establish the artificial airway, the low-pressure and high-volume endotracheal...

AI Technical Summary

Problems solved by technology

Monitor the cuff pressure 3 times a day as recommended by the guidelines, and the static cuff pressure can be basically maintained within the expected range, but clinically it is not possible to maintain the pressure at the 25-30cmH recommended by the guidelines 2 o

In addition to the amount of gas injected and the type of catheter, the internal pressure of the cuff is also related to the patient's body position,
