Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and more specifically, to a fixation device for a high-flow nasal tube. Background Technology

[0002] High-flow nasal cannula oxygen therapy (HFNC) is a treatment method that continuously provides patients with high-flow (8–80 L / min) inhaled gas through a high-flow nasal cannula, offering adjustable and relatively constant oxygen concentration (21%–100%), temperature (31–37°C), and humidity. It offers good comfort. As a novel respiratory support technology, it has been widely used clinically in recent years. The treatment equipment mainly includes an air-oxygen mixing device, a humidifier, a high-flow nasal cannula, and a high-flow nasal cannula. HFNC improves patients' gas exchange and partial ventilation by generating a certain level of positive end-expiratory pressure through the inhalation of high-flow gas, flushing out the physiological dead space of the upper respiratory tract, maintaining the function of the mucociliary clearance system with a constant temperature and humidity gas, and reducing upper airway resistance and work of breathing. 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 hypoxia combined with hypercapnia (type II respiratory failure). It should be noted that the limitations of HFNC should also be correctly understood. HFNC has specific clinical indications, relative contraindications, and absolute contraindications. Currently, the main recommended clinical applications of HFNC include: severe pneumonia, acute respiratory distress syndrome, other type I respiratory failure, weaning of critically ill ICU patients, weaning of post-surgical patients, and type II respiratory failure. Compared with conventional oxygen therapy, HFNC can reduce the intubation rate and mortality rate in patients with hypoxic respiratory failure.

[0003] When patients use high-flow nasal cannula oxygen therapy, the nasal cannula tubing is relatively long after it is connected to the ventilator tubing. The diameter of the nasal cannula tubing connected to the ventilator tubing is relatively large, and the front end of the tubing is soft and threaded. It is not secure when fixed with elastic bands and is easy to fall off. At the same time, frequent falls off can increase the workload of nurses, thereby affecting the patient's oxygen therapy effect and the progress of medical treatment.

[0004] Therefore, how to provide a fixation device for a high-flow nasal tube has become a technical problem that urgently needs to be solved in this field. Utility Model Content
