Oxygen flow and oxygen concentration conversion device of high-flow humidification oxygen therapy instrument

Abstract

The invention discloses an oxygen flow and oxygen concentration conversion device of a high-flow humidification oxygen therapy instrument, relates to the technical field of medical instruments, and aims to accurately adjust the oxygen concentration, the oxygen flow and oxygen concentration conversion device comprises a conversion device body, dustproof cover plates are fixedly mounted on the outer walls of the front side and the rear side of the conversion device body, and an oxygen pipe is fixedly mounted on the left side of the conversion device body; a side groove is formed in the right side of the conversion device body, a heating plate is fixedly installed in the side groove, a water tank is arranged at the top of the heating plate, a touch screen and an air outlet pipe are arranged on the upper surface of the conversion device body, an air filtering plate is fixedly installed in an air cavity, and the air cavity communicates with the mixing cavity. Air and oxygen mixed gas enters the water tank through the air and oxygen inlet to be humidified, the humidified air and oxygen mixed gas is discharged into the air outlet pipe through the air and oxygen outlet, the water content in the water tank is detected through the water level detector, when the water amount is insufficient, the third electromagnetic valve is opened, water enters the water tank through the third electromagnetic valve, and automatic water feeding is achieved.

Description

technical field [0001] The invention relates to the technical field of behavioral medical devices, in particular to an oxygen flow and oxygen concentration conversion device for a high-flow humidified oxygen therapy instrument. Background technique [0002] High-flow respiratory humidification therapy device refers to a treatment method that continuously provides patients with high-flow inhaled gas that can be adjusted and relatively constant oxygen concentration, temperature and humidity through high-flow dedicated nasal plugs or other patient interfaces. High-flow respiratory humidification therapy device , clinically commonly used in mild to moderate hypoxemia, such as hypoxic respiratory failure, such as ARDS, pneumonia, pulmonary fibrosis, cardiogenic pulmonary edema and other patients. It has a positive therapeutic effect on patients with simple hypoxic respiratory failure (type I respiratory failure), and may also have a certain therapeutic effect on some patients wit...

AI Technical Summary

Problems solved by technology

It has a positive therapeutic effect on patients with simple hypoxic respiratory failure (type I respiratory failure), and may also have a certain therapeutic effect on some patients with mild hypoxemia combined with hypercapnia (type II respiratory failure). Clinical studies of samples confirmed

[0003] The humidification oxygen therapy instrument in the prior art generally changes the oxygen concentration by adjusting the oxygen flow rate, the adjustment speed of the oxygen concentration is slow, and the oxygen concentration cannot be accurately set
