技术领域technical field
本发明涉及一种双管牙垫防护式高频喷射氧气吸痰导流器，特别是用于呼吸困难患者时双管牙垫防护式高频喷射氧气吸痰导流器装置设备。The invention relates to a double-tube dental pad protective high-frequency jet oxygen sputum suction deflector, in particular to a double-tube tooth pad protective high-frequency jet oxygen suction deflector device for patients with dyspnea.
背景技术Background technique
纤支气管镜( Fibreoptic bronchoscopy,FOB )是目前呼吸系统疾病检查和治疗的常用工具，是一种一次或多次的强刺激侵入性操作，检查中患者通常非常痛苦，术后心存余悸，导致检查和需多次操作的后续治疗难以进行，针对该问题，近年来临床上广泛采用静脉全身麻醉下的无痛FOB检查，以提高患者的依从性。然而由于全身麻醉药物对呼吸普遍存在抑制作用，且肺病患者多为老年人，术前常存在肺功能低下，加之FOB操作过程中占据通气路径，致气道空间狭窄，故在无痛FOB检查、无痛FOB活检或通过FOB进行灌洗治疗时，病人易产生通气障碍和术中缺氧性心律失常等并发症，需必备急救措施。但现有的通气工具多与FOB争夺气道空间、术中也常常需要麻醉医生站在头部进行面罩加压辅助通气，会造成FOB操作和抢救时许多不便，因此如何避免争夺气道现象，能方便通气管理并获得很好的通气效果，就成为无痛FOB检查中的无法解决问题；高频喷射通气（high frequency jetventilation, HFJV）能够提供高频率、低潮气量低于或接近解剖死腔量的快速喷射气流，易使气流通过狭小空间，在FOB占道的状态下，可维持足够的远端肺泡气体交换，在无痛FOB检查发生呼吸抑制时，不会发生低氧血症，且不会导致内源性气道压力过高，也不抑制血流动力学功能。随着FOB使用日趋增多，HFJV应用再次兴起，现有HFJV多采取以下介导工具：鼻导管、内镜面罩、气管导管及喉罩等来提高通气效率、改善血氧浓度。然而在无痛FOB检查中发现鼻导管介导HFJV存在喷射性压力易致鼻导管脱出、通气欠佳依赖于鼻腔的通透性，且鼻腔通透性较好的一侧常规为FOB置入路径的弊端，同时还存在鼻甲干燥和上呼吸道分泌物被吹进肺部造成或加重肺部感染的可能性；内镜面罩、气管导管及喉罩等介导HFJV虽然较鼻导管能显著提高通气效果，但并没有有效解决通气工具与FOB争夺气道空间的问题，也不能有效处理倒灌性误吸致缺氧的问题，且三者费用相对较高，操作也不够简便。Fiberoptic bronchoscopy (Fibreoptic bronchoscopy, FOB) is a common tool for the examination and treatment of respiratory diseases at present. It is difficult to carry out follow-up treatment that requires multiple operations. In response to this problem, painless FOB examination under intravenous general anesthesia has been widely used clinically in recent years to improve patient compliance. However, because general anesthetics generally have an inhibitory effect on breathing, and most patients with lung disease are elderly, preoperative lung function is often low, and the ventilation path is occupied during the FOB operation, resulting in narrow airway space. Therefore, painless FOB examination, During painless FOB biopsy or FOB lavage treatment, patients are prone to complications such as ventilation disturbance and intraoperative hypoxic arrhythmia, and emergency measures are necessary. However, most of the existing ventilation tools compete with the FOB for airway space, and the anesthesiologist often needs to stand on the head to perform mask pressurization to assist ventilation during the operation, which will cause a lot of inconvenience during FOB operation and rescue. Therefore, how to avoid the phenomenon of competing for the airway, To facilitate ventilation management and obtain a good ventilation effect has become an unsolvable problem in painless FOB examination; high frequency jet ventilation (HFJV) can provide high frequency, low tidal volume lower than or close to the anatomical dead space volume The rapid jet airflow makes it easy for the airflow to pass through the narrow space. When the FOB occupies the road, it can maintain sufficient distal alveolar gas exchange. When respiratory depression occurs in the painless FOB examination, hypoxemia will not occur, and it will not occur. Can lead to excessive intrinsic airway pressure and does not inhibit hemodynamic function. With the increasing use of FOB, the application of HFJV is on the rise again. The following mediation tools are mostly used in the existing HFJV: nasal catheter, endoscopic mask, endotracheal tube and laryngeal mask to improve ventilation efficiency and blood oxygen concentration. However, in the painless FOB examination, it was found that the nasal cannula-mediated HFJV has jet pressure, which can easily cause the nasal cannula to prolapse, and poor ventilation depends on the permeability of the nasal cavity, and the side with better nasal cavity permeability is usually the FOB insertion route At the same time, there is also the possibility of dry turbinates and upper respiratory secretions being blown into the lungs to cause or aggravate lung infection; although HFJV mediated by endoscopic masks, endotracheal tubes, and laryngeal masks can significantly improve the ventilation effect compared with nasal catheters , but it does not effectively solve the problem of the competition between the ventilation tool and the FOB for airway space, nor can it effectively deal with the problem of hypoxia caused by backflow aspiration, and the cost of the three is relatively high, and the operation is not easy enough.
