Description

Technical Field

[0001] The utility model relates to the technical field of artificial airway ventilation, in particular to a monitoring type nasal cavity ventilation device. Background Art

[0002] As one of the natural cavities for artificial ventilation, the nasal cavity is often used in clinic to establish artificial airway assisted ventilation with products such as masks, nasal oxygen tubes, and endotracheal tubes. However, due to differences in the patient's pathological state and anatomical structure, there are large differences in the applicable scenarios, ventilation effects, and degree of damage of related ventilation tools, which often lead to limited clinical diagnosis and treatment operations, difficulties in mechanical ventilation, and problems related to artificial airway intubation injuries. Endotracheal tube ventilation includes two types: nasal intubation subglottic positive pressure ventilation and supraglottic airway ventilation. The ventilation process of both can effectively prevent the tongue from falling back, and the ventilation effect is better, but it is more embarrassing for patients with difficult airway intubation, and it seriously limits the use of tools such as digestive tract diagnosis and treatment and cardiac ultrasound examination through the digestive tract, and even causes displacement and dislocation of the endotracheal tube body, ultimately leading to ventilation failure; in addition, airway intubation ventilation causes great damage to the inner wall mucosa of the nasal cavity, and patients are prone to pain, coughing, hoarseness, and other problems after surgery, which seriously affects the patient's postoperative recovery and quality of life. Traditional mask ventilation and high-flow oxygen ventilation can effectively reduce airway damage, but the former will interfere with clinical gastrointestinal endoscopy diagnosis and treatment activities, and the latter cannot meet the requirements of positive pressure ventilation. In severe cases, ventilation failure may occur, and even the patient's death may occur. At the same time, high-flow oxygen or positive pressure ventilation cannot accurately collect end-tidal carbon dioxide, and cannot effectively monitor the patient's respiratory status, making it difficult to assess the patient's respiratory, metabolic, circulatory and airway status, which may cause unexpected anesthesia medical accidents in severe cases. Therefore, there is an urgent need for an artificial airway ventilation tool that can meet the requirements of positive pressure ventilation oxygen, high-flow oxygen, and carbon dioxide monitoring.
