中枢神经严重病变、昏迷或经口气管插管病人,常伴随有吞咽功能的缺失,当患者咽部分泌物积聚增多时,病人不能做出吞咽动作或吐痰动作有效清除分泌物,致使分泌物积聚越来越多,最终溢入声门吸入肺部,导致吸入性肺炎或呼吸机相关性肺炎的发生。 Patients with severe central nervous system disease, coma or orotracheal intubation are often accompanied by a loss of swallowing function. When the patient's pharyngeal secretions increase, the patient cannot make swallowing action or spitting action to effectively remove secretions, resulting in secretions. More and more accumulation, eventually overflowing into the glottis into the lungs, leading to the occurrence of aspiration pneumonia or ventilator-associated pneumonia.
咽部分泌物积聚是吸入性肺炎和呼吸机相关性肺炎最主要原因,如何及时有效地清除口咽分泌物,避免分泌物较多积聚,是预防吸入性肺炎和呼吸机相关性肺炎的关键所在。 The accumulation of pharyngeal secretions is the main cause of aspiration pneumonia and ventilator-associated pneumonia.

The suction tube mouth is easy to adsorb mucosa and cause pharyngeal mucosal injury and bleeding. Frequent insertion of the suction tube through the nasal cavity and pharynx often causes extreme discomfort to the patient. Injury bleeding, irritating the throat causing vomiting, and even nausea and vomiting reaction caused by sucking, directly lead to the occurrence of aspiration; some people in the pharynx indwelling suction tube for regular or on-demand suction, but due to the design of the suction tube Defects, the suction tube is very easy to block, and the throat mucosa is more likely to break the bleeding. In short, the current routine use of suction tube to attract the removal of pharyngeal secretions, more effects, poor cleaning effect, pharyngeal secretions inhaled into the lungs remain high. In addition, the existing measures are quite cumbersome and the workload is large.

If the pharyngeal bottom is left by the suction tube, the port 105 is easily embedded in the esophageal opening, which tends to cause reflux of the stomach contents when attracted.
针对吸痰管上述缺点,本发明提供图2所示的咽部分泌物吸引导管的优选方案:两个水囊202及203。导管体尖端口105封闭成201、侧壁于纵轴向对称性开设两个吸引口103及104,于导管体102的外壁,吸引口横轴向的两旁,各装设一个所述的水囊202及203,所述水囊由硅胶薄膜制成,呈内空环圆形,环内壁薄膜与导管体102的外壁相联固定,在其注满水状态下,水囊半径比导管体大约3.0mm,厚度约3.0mm,水囊平面与与导管体102壁垂直,所述咽部分泌物吸引导管的导管体102壁内,嵌设一水囊注水管204,注水管前端相通的两个开口205及206分别置于两个水囊内,另一端随导管体出鼻腔后与导管体102分离,延长管外接带活塞开关和压力显示胶囊的注射器套头。 In view of the above disadvantages of the suction tube, the present invention provides a preferred embodiment of the pharyngeal secretion aspiration catheter shown in Figure 2: two water bladders 202 and 203.
