Description

一种通气导管Ventilation catheter 技术领域Technical field
本发明涉及一种通气导管,属医疗器械制作技术领域。The invention relates to a ventilation catheter and belongs to the technical field of medical device manufacturing.

人工气道的建立是临床医学最为常用的救护手段之一,文献表明:使用人工气道进行呼吸的患者,院内下呼吸道感染发病率10%-65%,病死率大于20%,而各种通气导管无论是气管插管还是气管切开后使用的套管,其固定在气管内的囊体因充入较大气压不可避免的会引起继发粘膜损伤,间歇性的降低压力势必会导致囊体上积聚的分泌物也包含流入的唾液或胃液等的下坠,进入支气管内,而此种分泌物通常含有大量致病菌,通气导管囊体上的分泌物下坠导致的肺部感染是当前难以彻底解决的临床问题。当前的方案是囊体上分泌物的持续或间歇吸引,吸引管开口位于囊体区域之上,与充盈后囊体的上缘有一定距离,致使分泌物无法吸引彻底,虽然下坠的量有所减少但任何感染源对于抵抗力低下的患者都是致命的,囊体上分泌物不能吸引彻底是当前最为棘手的困难。The establishment of artificial airway is one of the most commonly used rescue methods in clinical medicine. The literature shows that the incidence of lower respiratory tract infection in hospitals is 10%-65%, and the mortality rate is more than 20%. Whether the catheter is used for tracheal intubation or tracheal incision, the capsule fixed in the trachea will inevitably cause secondary mucosal damage due to the filling of the large air pressure. Intermittent reduction of pressure will inevitably lead to the capsule. Accumulated secretions also contain falling saliva or gastric juice, etc., into the bronchi, and this secretion usually contains a large number of pathogenic bacteria, and the lung infection caused by the secretion of secretions on the balloon of the ventilation catheter is difficult to completely solve at present. Clinical problem. The current solution is continuous or intermittent suction of the secretion on the capsule. The suction tube opening is located above the capsule area, and there is a certain distance from the upper edge of the filling capsule, so that the secretion cannot be attracted completely, although the amount of the falling is somewhat Reduced but any source of infection is fatal to patients with low resistance, and the secretion of cysts on the body is not the most difficult.
