Description

一种高负压无堵塞引流管  High negative pressure non-clogging drainage tube
技术领域Technical field
本发明涉及一种医疗器械,特别是一种高负压无堵塞引流管。The invention relates to a medical device, in particular to a high negative pressure non-clogging drainage tube.
背景技术Background technique
外引流是指在人体内腔、器官、关节、组织等与外界间建立开发通道的机械措施,其是外科的基本操作之一。现有的外科用引流管主要有单腔引流管和双套引流管2种。External drainage refers to the mechanical measures to establish a development channel between the human body cavity, organs, joints, tissues and the like, which is one of the basic operations of surgery. The existing surgical drainage tubes mainly include two types of single lumen drainage tubes and two sets of drainage tubes.
目前引流效果最好的是套管引流,即有一种利用低负压或重力引流原理的双套管引流管,包括置于病人体腔内起清洗作用的内置套管、引流作用的内置引流管、加药壶、加药导管和引流外界管,内置套管在内置引流管外,内置套管前端开口或不开口,内置引流管前端开口,两管的管壁上均开有多个引流侧孔;加药壶由以可拆装的接口套有接在一起的前部和后部构成,加药壶除了两端均设有外接头外,加药壶后部还有一内接头直接与加药壶后端接头连通,加药壶后部还附有冲洗和/或加药接口,内置套管后端套接固定于加药壶的前端外接头,内置引流管后端接在加药壶后部的内接头上并与套接在加药壶后端外接头的引流外界管相连通。At present, the best drainage effect is the cannula drainage, that is, a double-tube drainage tube utilizing the principle of low negative pressure or gravity drainage, including a built-in sleeve placed in the body cavity of the patient for cleaning, a built-in drainage tube for drainage, The medicine pot, the drug feeding catheter and the drainage external tube, the built-in sleeve is outside the built-in drain tube, the front end of the built-in sleeve is open or not open, the front end of the built-in drain tube is open, and the tube wall of the two tubes is provided with a plurality of drainage side holes The medicine pot is composed of a front part and a rear part which are connected together by a detachable interface sleeve, and the medicine pot has an outer joint at both ends, and an inner joint at the back of the medicine pot directly and the medicine is added. The back end of the pot is connected, and the back of the medicine pot is also provided with a flushing and/or dosing interface. The back end of the built-in sleeve is fixed to the front end of the medicine pot, and the rear end of the built-in drain tube is connected to the medicine pot. The inner joint of the portion is connected to the draining outer tube that is sleeved at the outer joint of the rear end of the dosing pot.
在手术后,将双套管引流端置于需引流的创面,从体表引出用缝线固定,引流外界管后端接负压引流装置、吸引器或引流袋等。如果需要接负压引流时,必须打开冲洗接口处开口,让空气或冲洗液进入官腔进行创面冲洗和引流。使用过程中,为了防止引流管阻塞,可以更换内置引流管。该双套管具有术后导入引流、创面冲洗、创面给药、防止内置引流管堵塞等功能,是目前功能最齐全,最先进的术后引流管,但是其仍然存在以下缺陷:1)不能完全解决影响引流效果的关键“瓶颈”问题——引流管堵塞(注:虽然内置引流管可以更换,但是套在内置引流管外的内置套管的套管引流孔仍然会堵塞);2)当利用负压主动引流时,套管引流需空气或药液不断进入被引流区,容易在局部形成腔隙,也增加了空气中得细菌进入被引流区的危险;3)只能应用重力或低负压进行引流,而重力及低负压引流的最大缺点是引流的不及时、不彻底,亦难在短时间里消除残留死腔;4)引流管插入人体并使用一段时间后,引流管与创面之间容易形成粘连,不容易拔出,并在拔出过程中具有引发创面出血的危险。引流术是外科的基本技术,应用极广,但由于以上原因引流失败的个案还时有发生。After the operation, the double-cannula drainage end is placed on the wound surface to be drained, and the suture is fixed from the body surface, and the negative pressure drainage device, the suction device or the drainage bag is connected to the rear end of the external tube. If negative pressure drainage is required, the opening at the irrigation interface must be opened to allow air or irrigation fluid to enter the official cavity for wound irrigation and drainage. In order to prevent the drainage tube from being blocked during use, the built-in drainage tube can be replaced. The double cannula has the functions of postoperative drainage, wound washing, wound administration, prevention of clogging of the built-in drainage tube, etc. It is the most complete and advanced postoperative drainage tube, but it still has the following defects: 1) can not be completely Solve the key "bottleneck" problem affecting the drainage effect - the drainage tube is blocked (Note: Although the built-in drainage tube can be replaced, the casing drainage hole of the built-in sleeve outside the built-in drainage tube will still be blocked); 2) When utilizing When negative pressure is actively drained, the casing drainage requires air or liquid to continuously enter the drainage area, which is easy to form a cavity locally, and also increases the risk of bacteria in the air entering the drainage area; 3) only gravity or low negative can be applied Pressure is used for drainage, and the biggest disadvantage of gravity and low negative pressure drainage is that the drainage is not timely and incomplete, and it is difficult to eliminate residual dead space in a short time; 4) After the drainage tube is inserted into the human body and used for a period of time, the drainage tube and the wound surface It is easy to form adhesions, is not easy to pull out, and has the risk of causing bleeding of the wound during the extraction process. Drainage is the basic technique of surgery, and it is widely used. However, cases of failure due to the above reasons have occurred from time to time.
