口腔颌面部感染是临床常见病,经常规的局部治疗和全身治疗;绝大多数病例能够很快治愈,但有少数病例效果不佳,针对少数常规治疗效果不佳的病例,我们参考外科闭合冲洗吸引法制作一闭合冲洗吸引装置,经临床在8例常规治疗效果不佳的病例上应用,取得了满意效果,达到治愈的目的,现介绍如下: 1 材料与方法 1.1 闭合冲洗吸引装置包括三部分:①冲洗管,②吸引管,③负压吸引球。用一次性输液器和一次性负压吸引球制作,取一次性输液器一个摘下连接针头的细管,去除针头留作冲洗管用,余下部分粗管作吸引管用。在粗管末端5.0cm处烫一直径略小于细管的孔用结扎丝将作冲洗用细管从小孔引入吸引管中并从吸引管末端引出约1.0cm,使冲洗管位于吸引管中。根据引流范围在吸引管末端管壁剪数个侧孔。 1.2 使用方法:局部麻醉下沿原引流口或重作切口将脓腔分隔分离开,通过切口将引流管及冲洗管置 Oral and maxillofacial infection is a common clinical disease, conventional local treatment and systemic treatment; the vast majority of cases can be quickly cured, but a small number of cases ineffective, for a small number of conventional treatment ineffective cases, we refer to the surgical closure Flushing suction method to make a closed flush suction device, the clinical application of 8 cases of conventional treatment ineffective, and achieved satisfactory results, to achieve the purpose of cure, are as follows: 1 Materials and methods 1.1 closed flush suction device, including three Part: ① flushing tube, ② suction tube, ③ negative pressure to attract the ball. Disposable infusion set and one-time vacuum suction ball making, take a disposable infusion tube connected to a small needle, remove the needle for flushing tube, the remaining part of the thick tube for suction tube use. At 5.0 cm at the end of the coarse tube, a hole slightly smaller in diameter than the thin tube was punctured with a ligature wire for introduction into the aspiration tube through the orifice and about 1.0 cm from the distal end of the aspiration tube, placing the irrigation tube in the aspiration tube. Depending on the drainage area, several side holes are cut at the tube end of the suction tube. 1.2 Usage: Under the local anesthesia along the original drainage port or re-made incision to separate the abscess cavity, the drainage tube and the irrigation tube through the incision
