Description
技术领域technical field
本发明涉及一种引流装置，具体涉及一种对患部深部组织的引流和冲洗，有利于提高负压引流和冲洗的治疗效果的防堵负压冲洗引流装置。The invention relates to a drainage device, in particular to an anti-blocking negative pressure flushing and drainage device for drainage and flushing of deep tissue in an affected part, which is beneficial to improving the therapeutic effect of negative pressure drainage and flushing.
背景技术Background technique
外科引流为的是将人体组织间或体腔中积聚的脓、血、液体异常物质包括脓液、积血或坏死组织等导引至体外，预防及治疗感染与促进组织愈合。临床上应用的外科引流管种类很多，广泛用于伤口、胸腔、脑腔、胃肠道、胆道、脓肿等的引流，是临床治疗疾病的重要措施。引流不畅常导致体内脓、血、液体积聚，继发严重感染或已发生感染难以控制，是预防感染及治疗感染的最重要的措施，甚至比抗生素应用更为重要，是临床医学领域公认的最基本治疗原则之一。Surgical drainage is to guide pus, blood, and abnormal liquid substances, including pus, blood or necrotic tissue, accumulated between human tissues or body cavities to the outside of the body to prevent and treat infection and promote tissue healing. There are many types of surgical drainage tubes used clinically, which are widely used in the drainage of wounds, thoracic cavity, brain cavity, gastrointestinal tract, biliary tract, abscess, etc. It is an important measure for clinical treatment of diseases. Poor drainage often leads to the accumulation of pus, blood, and fluid in the body, secondary serious infection or difficult to control infection that has occurred. It is the most important measure to prevent and treat infection, even more important than the application of antibiotics. One of the most basic principles of treatment.
当冲洗、引流、支撑等同时进行时往往需要放置多根引流管，有时甚至需要开设多个引流口或反复多次手术清除坏死或感染灶，也给病人带来痛苦，增加了患者病死率，并造成严重的经济和社会负担。When flushing, drainage, and support are performed at the same time, it is often necessary to place multiple drainage tubes, and sometimes even need to open multiple drainage ports or perform repeated operations to remove necrotic or infected foci, which also brings pain to the patient and increases the mortality rate of the patient. And cause serious economic and social burden.
由于单腔式引流管结构简单，目前已经出现了多种可冲洗式多腔引流管，但是采用现有技术中的引流管对患者深部组织进行负压引流等时，在负压的作用下患者深部的坏死组织，凝血块，肠网膜，肠管及软组织等仍然十分容易堵塞引流管，仍然达不到持续通畅引流的效果，一直是困扰临床医生的难题。Due to the simple structure of the single-chamber drainage tube, a variety of flushable multi-chamber drainage tubes have appeared. Deep necrotic tissue, blood clots, intestinal omentum, intestinal tube and soft tissue are still very easy to block the drainage tube, and the effect of continuous smooth drainage is still not achieved, which has always been a difficult problem for clinicians.
