Description

A humidified oxygen therapy nasal cannula that is easy to wear

Technical Field

The utility model belongs to the technical field of medical equipment and provides a humidified oxygen therapy nasal catheter which is easy to wear.

Background technique

High-flow nasal cannula (HFNC) is an oxygen therapy method that directly delivers a certain oxygen concentration of air-oxygen mixed with high-flow gas to the patient through a nasal cannula that does not require sealing. This gas has the characteristics of high flow, precise oxygen concentration and heated humidification. In recent years, it has been used in adult patients, especially in intensive care units (ICUs), mainly for patients with acute respiratory failure (RF), acute pulmonary edema, chronic obstructive pulmonary disease (COPD), and perioperative patients, making high-flow nasal cannula oxygen therapy gradually become an option for adult patients with hypoxemia in addition to non-invasive positive pressure ventilation (NIPPV).

By adopting the above method, the existing high-flow nasal oxygen therapy can generate a certain level of positive end-expiratory pressure (PEEP) by inhaling high-flow gas while the patient keeps his lips closed. For patients whose lips cannot be closed, although we sometimes use high-flow devices to connect masks to supply oxygen in clinical practice, such a connection method mainly guarantees that the patient is provided with "constant oxygen concentration" and "fully warmed and humidified" gas. Such gas is not delivered to the patient through nasal congestion, and it is impossible to fully achieve the corresponding physiological effect of high-flow nasal oxygen therapy. Studies have shown that only high-flow gas delivered to patients through nasal congestion can significantly reduce the gas repeatedly breathed in the dead cavity of the upper airway, thereby playing a "physiological dead cavity flushing effect", and at the same time produce a certain "positive end-expiratory pressure effect", increasing the lung volume at the end of exhalation. For patients who breathe with their mouths open (habitually open-mouth breathing, open-mouth breathing in sleep, and open-mouth breathing due to disease), the effect of HFNC on PEEP disappears, affecting the treatment effect. It is a prerequisite for patients receiving HFNC treatment to keep their lips closed to achieve good treatment results.
