The utility model discloses a closed thoracic drainage device, which comprises a puncture assembly, an expansion assembly and a thoracic drainage tube; the puncture assembly comprises a syringe, and the core coat of the syringe is provided with a sleeve. The tip of the core of the needle penetrates the sleeve. When puncturing, the core and the sleeve of the syringe enter the thoracic cavity together; the expansion assembly comprises a first guide rod, a guide tube, a skin expander and a fixing sheath, and the first guide rod. A guide rod is put into the thoracic cavity through a cannula, and the guide tube is a rigid tube. The guide rod is inserted into the thoracic cavity along the first guide rod. The diameter of the expander is larger than that of the thoracic drainage tube. The expander is inserted into the fixed sheath, and the expander and the fixed sheath are combined together and then sent into the thoracic cavity along the guide tube. The thoracic drainage tube is fed into the thoracic cavity through the fixed sheath, and the thoracic drainage tube is fed into the thoracic cavity. After entering the thoracic cavity, it is fixed to the skin by silk thread. The utility model can quickly puncture and implant a thoracic drainage tube, which is convenient and safe to operate, has little damage to patients and can significantly reduce the occurrence of complications.

胸腔闭式引流器
本技术涉及医疗器械
,特别是涉及一种胸腔闭式引流器。
技术介绍
胸腔闭式引流作为一种治疗手段广泛地应用于血胸、气胸和脓胸的引流,对于疾病的治疗起着十分重要的作用。临床上常规的胸腔闭式引流方法是局部麻醉后,常规消毒铺单,在穿刺引流点切开皮肤,作一切口,插入止血钳逐层分离肌肉组织,沿肋骨上缘分入胸腔,使用止血钳夹持带侧孔的胸腔引流管经切口插入,缝合切口,经皮肤缝线固定胸腔引流管,防止胸腔引流管从胸膜腔内滑出,胸腔引流管外接水封瓶或袋闭式引流装置,达到治疗目的后,剪去固定胸腔引流管的缝线,拔出胸腔引流管。目前临床上使用的胸腔闭式引流存在着以下的不足之处:1、若病人肥胖或胸壁较厚,止血钳不够深,不能有效撑开胸壁,置管困难且费时;2、止血钳分离肋间肌肉及胸膜时,损伤大,部分病人术后疼痛严重;3、容易损伤胸腔内器官(肺脏或膈肌),严重不良操作可能会损伤肝脏或脾脏等腹腔器官;4、操作费时,不能快速完成,若皮肤切口小,增加操作难度,若皮肤切口大,则损伤较大。
