Transnasal high-flow-capacity oxygen therapy pressure monitoring system and method

Abstract

The invention provides a transnasal high-flow-capacity oxygen therapy pressure monitoring system and method. A pressure detection device detects the airway pressure in a breathing pipe of transnasal high-flow-capacity oxygen therapy equipment, obtains detection signals and sends the detection signals to a control device. The control device receives the detection signals sent by the pressure detection device after receiving first acquisition commands to obtain first detection signals and receives the detection signals sent by the pressure detection device after receiving second acquisition commands to obtain second detection signals. The control device conducts analog-digital conversion on the first detection signals and the second detection signals to obtain first detection data and second detection data respectively, conducts calculation according to the first detection data and the second detection data to obtain the airway pressure value of a patient and outputs the pressure value. The airway pressure of the patient is obtained accordingly through detection of the airway pressure in the breathing pipe, pressure monitoring reference is provided for medical staff, and the clinical use risks are lowered.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to a pressure monitoring system for nasal high-flow oxygen therapy and a monitoring method thereof. Background technique [0002] At present, the respiratory treatment trend of NICU (Neonatal intensive care center, Neonatal Intensive Care Center) is increasingly developing in the direction of non-invasive nasal ventilation, and nasal high-flow oxygen therapy is a nasal ventilation mode developed in recent years. High-humidity air-oxygen mixer gas to achieve respiratory therapy for patients. The ventilation mode of nasal high-flow oxygen therapy equipment adopts π-shaped nasal oxygen tube, which is connected to the patient's nostril in a non-sealed manner. After the gas enters the nostril, it leaks from the nasal congestion of the nasal oxygen tube and the gap in the nasal cavity, so as to achieve air flow in the patient's nose. Create positive airway pressure. [0003] The nasal ...

AI Technical Summary

Problems solved by technology

[0003] The nasal oxygen tube accessories used in traditional nasal high-flow oxygen therapy equipment are small and soft, and pressure sampling ports cannot be added to the nasal congestion of the nasal itching tube. Therefore, nasal high-flow oxygen therapy equipment generally does not monitor the patient's airway pressure. High risk in clinical use
