Nasal high-flow humidification oxygen therapy noninvasive ventilation equipment, control method and control system

Abstract

The invention discloses non-invasive ventilation equipment for nasal high-flow humidification oxygen therapy, a control method and a control system, and relates to the technical field of oxygen therapy. An oximeter in the equipment is used for obtaining the oxyhemoglobin saturation of a tester; the target gas output device is used for acquiring the respiratory rate of a tester and outputting gas meeting set conditions; the set conditions comprise a first condition, a second condition and a third condition; the first condition comprises a condition that the oxygen concentration is within a first numerical value range; the second condition is that the temperature and the humidity are in a second numerical value range; the third condition is a condition that the flow is in a third numerical value range; the central control device is used for calculating an ROX index according to the oxyhemoglobin saturation and the respiratory rate and calculating an oxygenation index according to the oxyhemoglobin saturation in the intelligent ventilation mode; and adjusting the first value range, the second value range and the third value range according to the ROX index and the oxygenation index. According to the invention, gas meeting real-time requirements can be provided.

Description

technical field [0001] The invention relates to the technical field of oxygen therapy, in particular to a non-invasive ventilation device, a control method and a control system for nasal high-flow humidified oxygen therapy. Background technique [0002] Transnasal high-flow humidified oxygen therapy (HFNC) is a new type of oxygen therapy. The nasal high-flow humidified oxygen therapy instrument mainly includes a flow generating device, an air-oxygen mixing device, a heating and humidifying device, and a nasal oxygen tube oxygen delivery circuit. . The HFNC instrument can provide gas with 21%~100% oxygen concentration, 31℃~37℃ temperature, and 2L / min~80L / min flow rate, which is used to treat mild to moderate type I respiratory failure, mild respiratory distress, and mild ventilation function. Obstacles, intolerance or contraindications to traditional oxygen therapy or non-invasive positive pressure ventilation. [0003] The non-invasive ventilation in the nasal high-flow hu...

AI Technical Summary

Problems solved by technology

[0004] The problems existing in the existing nasal high-flow humidified oxygen therapy instrument technology are: the existing nasal high-flow humidified oxygen therapy instrument on the market does not provide treatment plan suggestions, and the treatment parameters of the testers are completely set by the staff based on experience.

As a new respiratory support method, HFNC instrument can save the life of the tester in time and alleviate the condition of the tester if it is clinically applied properly.
