Description

A Tracheostomy Device Based on Nasal High Flow Heating and Humidification

technical field

The utility model relates to the technical field of gas cutting tubes, in particular to a heating and humidifying gas cutting device based on nasal high flow rate.

Background technique

Tracheotomy to establish an artificial airway is an important measure to solve airway obstruction and improve ventilation function in critically ill patients. However, after tracheostomy, the warming, humidification, and purification effects of the upper airway on the inhaled gas are lost, resulting in easy drying of the respiratory mucosa, thickening of the sputum, and formation of sputum plugs, resulting in a decrease in the defense function of the respiratory system and opening the door for pathogens to invade. conditions are created. Therefore, reducing the loss of airway water and strengthening airway humidification in patients after tracheotomy are important measures to keep the airway moist, sputum diluted, and airway unobstructed, and are also the key to reducing the incidence of pulmonary infection.

Nasal high-flow humidified oxygen therapy (HFNc), as a new respiratory support technology, has been widely used clinically in recent years. . It mainly focuses on providing patients with relatively constant oxygen concentration (21-100%), temperature (31-37°C) and high-flow (8-80L/min) gas with humidity, and oxygen therapy through nasal congestion, which has a good comfort. HFNc can generate a certain level of positive end-expiratory pressure by inhaling high-flow gas, flush out the physiological dead space of the upper respiratory tract, maintain the function of the mucociliary clearance system with constant temperature and humidity gas, and reduce the patient's upper airway resistance and breathing work, etc. Ventilation and partial ventilation functions.

For patients with tracheostomy who do not require mechanical ventilation and need to use nasal high-flow humidified oxygen therapy due to disease factors, a tracheotomy interface will be used to connect the tracheotomy catheter and nasal high-flow humidified oxygen therapy circuit. Although nasal high-flow humidified oxygen therapy can provide gas with a relatively constant temperature and humidity, for patients with high airway humidification requirements, there will still be cases of viscous sputum and formation of sputum scabs. Moreover, the gas exhaled by the patient is easily affected by the temperature difference to form water droplets, and the water droplets flow into the patient's trachea, causing secondary damage to the patient.

Therefore, how to provide a new type of tracheotomy device to increase the temperature and humidity of oxygen so as to prevent the water droplets produced by respiration from flowing back into the patient's trachea is a technical problem to be solved urgently by those skilled in the art.
