Description
技术领域technical field
本实用新型涉及医疗设备的技术领域，具体是涉及一种人工气道高流量湿化氧疗密闭吸引的结构。The utility model relates to the technical field of medical equipment, in particular to a structure for airtight suction of artificial airway high-flow humidified oxygen therapy.
背景技术Background technique
医疗领域中，为保证气道通畅，将气管导管直接放入气道内而建立的气体通道为人工气道，通过人工气道能纠正患者的缺氧状态，改善通气功能和有效地清除气道内分泌物。但是在此情况下，如对人工气道湿化不够，则容易在人工气道内形成痰痂而堵塞气道，影响肺功能，增加患者的危险。In the medical field, in order to ensure the unobstructed airway, the gas channel established by placing the endotracheal tube directly into the airway is an artificial airway, which can correct the hypoxic state of the patient, improve the ventilation function and effectively clear the airway endocrine. things. But in this case, if the humidification of the artificial airway is not enough, it is easy to form phlegm scab in the artificial airway and block the airway, affecting lung function and increasing the risk of patients.
目前，临床上常采用气泡式湿化给氧联合雾化吸入湿化、气道内持续滴入湿化液湿化、人工鼻湿化以及温湿化器恒温湿化等方法温湿化气道。2017年英国胸科协会医疗机构及急诊室成人用氧指南建议：对于气管切开需长期氧疗的病人，可考虑使用大容量氧气湿化装置，特别是对于分泌物排出不畅的病人。另外因为有证据表明气泡式湿化给氧有感染的风险，故指南不推荐使用。且采用雾化吸入的方式存在如操作不当或固定不妥时易出现药液倒流的问题，影响疗效且增加感染的风险；采用气道内持续滴入湿化液的方式存在容易使患者产生刺激性咳嗽、心率增快、憋闷、血氧分压下降、血压升高等不良并发症，对患者影响较大；采用人工鼻湿化的方式存在价格较贵，且在污染后需立即更换，使用成本高，且不适用于痰液黏稠者或二氧化碳潴留者，使用范围受限大；采用温湿化器恒温湿化的方式水虽能克服以上缺陷，但是由于其现有结构的不合理，不能满足患者吸入气体流速的需要，且不能解决主动湿化氧疗装置给患者通气带来的额外无效腔和气道阻力增加的问题。并且以上几种方式的使用吸引方法由于均为开放式，无法避免在建立人工气道时可能引起交叉感染的问题，安全保障性不够。At present, methods such as air bubble humidification oxygen supply combined with atomized inhalation humidification, continuous dripping of humidification solution into the airway, artificial nose humidification, and constant temperature humidification with a thermohumidifier are often used in clinic to warm and humidify the airway. The 2017 British Thoracic Society Medical Institutions and Emergency Room Oxygen Guidelines for Adults suggested that for patients requiring long-term oxygen therapy after tracheotomy, a large-capacity oxygen humidification device may be considered, especially for patients with poor discharge of secretions. In addition, the guidelines do not recommend the use of bubble-type humidified oxygen because of the evidence that there is a risk of infection. Moreover, the method of nebulization inhalation has the problem of backflow of the liquid medicine if it is improperly operated or fixed, which affects the curative effect and increases the risk of infection; the method of continuously dripping humidification liquid into the airway is likely to cause irritation to the patient. Undesirable complications such as coughing, increased heart rate, depression, decreased blood oxygen partial pressure, and increased blood pressure have a greater impact on patients; artificial nasal humidification is more expensive, and it needs to be replaced immediately after contamination, and the cost of use is high , and not suitable for those with viscous sputum or carbon dioxide retention, the scope of use is greatly limited; although the method of constant temperature humidification with a thermohumidifier can overcome the above defects, due to its unreasonable existing structure, it cannot meet the needs of patients. Inspiratory gas flow rate needs, and cannot solve the problem of additional dead space and increased airway resistance brought by active humidified oxygen therapy device to patient ventilation. And the use suction method of above several modes is owing to being open, can't avoid the problem that may cause cross-infection when setting up artificial airway, and security is not enough.
