摘要
目前临床用于负压封闭引流(VSD)的普通负压引流瓶无定量引流及自动切断引流功能.在持续引流时,医护人员不仅要观察引流瓶是否过满,以免引流液进入负压源造成引流中断,还要观察是否有大量新鲜血液被吸出,以防造成患者失血过多.出现上述两个问题对患者均造成一定风险.为此,我们设计制作了一种具有自动切断持续引流功能的'一次性定容负压引流装置',既能防止引流液回流进入负压源造成引流中断,又能防止出血后仍持续引流造成大出血.该装置结构简单、安全可靠,值得临床推广使用.
The common negative pressure drainage bottle used in the vacuum sealing drainage (VSD) cannot quantitative and automatically cut off. Excessive drainage damages the negative pressure source, causes drainage interruption, so once drainage was continuously performed, medical staff need to closely observe drainage bottle calibration. It was also important to known whether there was a large amount of fresh blood sucked out during continuous drainage because it could lose too much blood. To solve these two problems, we designed a kind of negative pressure drainage device, which volume was constant, with the function of automatic cutting off continuous drainage. It can not only prevent drainage fluid flowing back to the negative pressure source and cause drainage interruption, but also prevent massive blood loss from continued drainage after the hemorrhage. We could benefit from this device, which possess many advantages, such as simple structure, security and reliability. It is worthy promoting in the clinical work.
