Description
技术领域
本发明涉及医用引流管，具体地指一种带锁定线系统双腔猪尾巴引流管。
背景技术
猪尾巴引流管是在手术中或通过B超、X射线、CT等成像设备引导将导管置入胸、腹、心包腔等组织积液积脓腔，进行引流及腔内灌注或冲洗，在临床上应用广泛。由于猪尾巴导管表面光滑，X光线下显影清晰、生物相容性好、留置时间长、内腔大、流量大、不易变形变质，现已逐步取代了以往使用的单腔普通导管。
猪尾巴引流管尾端卷曲，形成猪尾，卷曲后可有效的防止导管从进入口脱出，从而脱离体腔，还能防止管体的位移，减少并发症的发生。带锁定线的猪尾巴引流管可将导管尾端卷曲锁定并调整卷曲弧度，使之更适合多部位手术的引流，适应性极佳，由于尾端有锁定线锁死，在病人活动下也不易脱出。
现在市面上的猪尾巴引流管的锁定系统基本为滑套式、圆柱式和Y型接头式，这几种结构的加工、组装工艺复杂，外形棱角过多，贴附在病人身体上带来不适。而最大的缺点是锁定后，锁定线收纳困难，造成锁定线及拉线环裸露在系统外，此外，锁定线与外界连通处易漏气漏液，导致细菌沿锁定通道进入导管，造成二次感染，且锁定线外露极易挂扯到拉线致使导管移动或滑脱引发并发症。另外，现有猪尾管为单腔设计，给冲洗注药带来难。
发明内容
本发明目的在于克服上述现有技术的不足而提供一种带锁定线系统双腔猪尾巴引流管，该引流管结构简单，性能可靠，冲洗方便，能够将锁定线及拉线环完全封闭，且连接冲洗腔道，使引流管有单独的冲洗通道来进行注药冲洗，此外，还能有效的防止漏气漏液现象而产生的二次感染，更加安全可靠。
实现本发明目的采用的技术方案是一种带锁定线系统双腔猪尾巴引流管，包括锁定线和猪尾巴引流管，所述猪尾巴引流管的一端为猪尾卷曲端，另一端为引流排泄端；所述锁定线的一端与猪尾巴引流管的猪尾卷曲端连接；该带锁定线系统双腔猪尾巴引流管还包括：
导管固定座；
锁定线连接座，其固定在所述导管固定座的上方，所述猪尾巴引流管的引流排泄端依次穿过导管固定座和锁定线连接座；所述锁定线连接座上设有向外伸出的锁定线固定轴，且所述锁定线连接座上还开有轴孔；
锁定压块，包括外壳及连接在外壳上的转轴，所述转轴安装在轴孔中，且转轴绕轴孔转动；
拉线环，所述锁定线的一端依次穿过导管固定座和锁定线连接座后与拉线环连接；以及，
冲洗腔，其包括进水口和出水口，所述出水口穿过所述导管固定座与猪尾巴引流管连通。
进一步地，所述冲洗腔的进液口设有护帽。
进一步地，所述锁定线的另一端穿过锁定线连接座的出线口处用密封圈固定，且用硅胶封闭。
更进一步地，所述卡线接头安装在所述锁定线连接座上，且所述锁定线与卡线接头之间设有接头密封圈。
本发明带锁定线系统双腔猪尾巴引流管还包括卡线接头，所述卡线接头安装在锁定线连接座上，所述锁定线的另一端穿过卡线接头后与猪尾巴引流管的猪尾卷曲端连接，且所述锁定线与卡线接头的连接处设有接头密封圈。
本发明带锁定线系统双腔猪尾巴引流管具有以下优点：
1、本发明中锁定压块能转动至外壳完全罩住锁定线固定轴上，形成一收纳腔，使锁定线及拉线环完全封闭，无突出及裸露线头，使病人活动更加方便、安全。
2、猪尾巴引流管采用双腔设计，且导管固定座带连接冲洗腔道，使引流管有单独的通道来进行注药冲洗，方便快捷，避免了废液回流到体内引发感染。
3、锁定线与外界连通处用硅胶封闭，外部用密封圈固定，由于硅胶的特性使出线口完全封闭，有效的防止漏气漏液现象而产生的二次感染，更加安全可靠。
附图说明
图1是本发明带锁定线系统双腔猪尾巴引流管的结构示意图。
图2是本发明带锁定线系统双腔猪尾巴引流管的剖面示意图。
图3是发明带锁定线系统双腔猪尾巴引流管完成锁定后关闭收纳腔示意图。.
具体实施方式
下面结合附图和具体实施例对本发明作进一步的详细说明。
如图1所示，本发明带锁定线系统双腔猪尾巴引流管包括猪尾巴引流管6、锁定线8、导管固定座5、锁定线连接座2和锁定压块10。
其中，猪尾巴引流管6的一端为猪尾卷曲端11，另一端为引流排泄端1；锁定线连接座2固定在导管固定座5的上方，猪尾巴引流管6的引流排泄端1依次穿过导管固定座5和锁定线连接座2；锁定线连接座2上设有向外伸出的锁定线固定轴9，锁定线固定轴9可以根据锁定线的长度设置一个或者多个，锁定线连接座2上还开有轴孔(图中未视出)。锁定压块10包括外壳及连接在外壳上的转轴，转轴安装在轴孔中，且转轴绕轴孔沿锁定线固定轴9伸出方向转动；锁定线8的一端依次穿过导管固定座5和锁定线连接座2后连接有一拉线环7。
本发明带锁定线系统双腔猪尾巴引流管还包括冲洗腔4，冲洗腔4包括进液口和出液口，出液口穿过导管固定座5与猪尾巴引流管6连通；进液口设有护帽3。
作为本发明的一种优选实施方式，如图2所示，锁定线8的一端穿过锁定线连接座2的出线口处用密封圈14固定，且用硅胶14封闭出线口；锁定线8的另一端穿过卡线接头7后与猪尾巴引流管6的猪尾卷曲端11连接。卡线接头12安装在锁定线连接座2上，且锁定线8与卡线接头12之间设有接头密封圈15。卡线接头12用于固定锁定线8。
使用本发明带锁定线系统双腔猪尾巴引流管时，调整好所需猪尾卷曲端11的锁定弧度后，将锁定线8的拉动端(图中上端)，缠绕在锁定线固定轴9上，然后转动锁定压块10直至外壳完全罩住锁定线固定轴9上，形成一收纳腔16，如图3所示，此时，锁定线8的拉动端(图中上端)被封闭在收纳腔16内，从而避免裸露在外，即锁定线连接座2和锁定压块10构成锁定性收纳系统。为了方便固定锁定压块10，还可以在锁定线连接座2上设有卡槽，在锁定压块10设置卡扣，锁定压块10的外壳完全罩住锁定线固定轴9上后，通过卡扣卡入卡槽内实现对锁定压块10的固定，或者使用其他固定结构均可。
