技术领域technical field
本实用新型属于医疗器械技术领域，尤其涉及一种适用于气管切开/气管插管患者的防药液倾倒雾化器。The utility model belongs to the technical field of medical devices, in particular to an anti-medicine liquid dumping atomizer suitable for patients with tracheotomy/trachea intubation.
背景技术Background technique
建立人工气道是临床上抢救危重患者保持其呼吸道通畅以保证氧供给的主要方法之一。但人工气道的建立，使呼吸道失去生理屏障及恒温、湿化作用，致黏膜干燥，呼吸道大量水分丧失，分泌物干结，易形成痰痂阻塞呼吸道。Establishing an artificial airway is one of the main methods for clinically rescuing critically ill patients to keep their airways open to ensure oxygen supply. However, the establishment of an artificial airway makes the respiratory tract lose its physiological barrier, constant temperature, and humidification, resulting in dry mucous membranes, a large amount of water loss in the respiratory tract, dry secretions, and easy formation of sputum scabs to block the respiratory tract.
氧气雾化吸入疗法是临床上较好的物理与化学治疗相结合的治疗急慢性呼吸系统疾病的方法，它通过将药液变成细微的气雾，随着病人吸气进入呼吸道，可以充分湿化呼吸道，使药液直接到达肺部,达到消除炎症、稀释痰液、镇咳、解除支气管痉挛、改变通气功能的目的。氧气雾化吸入疗法以起效快、操作简便、药物用量小、不良反应轻、患者易于接受等优点而被广泛应用于临床。Oxygen atomization inhalation therapy is a clinically better combination of physical and chemical therapy for the treatment of acute and chronic respiratory diseases. Dilute the respiratory tract, so that the medicinal liquid can directly reach the lungs, and achieve the purpose of eliminating inflammation, diluting sputum, antitussive, relieving bronchospasm, and changing ventilation function. Oxygen nebulization inhalation therapy is widely used in clinical practice due to its advantages of fast onset, simple operation, small drug dosage, mild adverse reactions, and easy acceptance by patients.
若将现有的氧气雾化面罩用于已经建立人工气道的患者，若面罩在使用过程中操作护理不当，会使药液容易倒流，而且产生的药雾流失多，影响疗效。目前临床上一般采用间歇湿化法进行人工气道湿化，但此种方法若掌握不好湿化液的剂量，会使滴入气道内湿化液量过大，导致患者出现刺激性咳嗽、心率增快、血氧饱和度下降等不良反应。If the existing oxygen atomization mask is used for patients who have established an artificial airway, if the mask is not properly operated and cared for during use, the medicinal liquid will easily flow back, and the generated medicinal mist will be lost, which will affect the curative effect. At present, the intermittent humidification method is generally used for artificial airway humidification in clinical practice. However, if the dosage of the humidification solution is not properly controlled in this method, the amount of humidification solution dripped into the airway will be too large, resulting in irritating cough, Increased heart rate, decreased blood oxygen saturation and other adverse reactions.
