留置导尿管后尿路感染发生率很高,我们制作了一种尿液引流装置,能有效地减少尿路感染。在引流管的上部插入一根方向朝下的Y形塑料管(如图)。Y形管外口由一带柄的塞子封闭,管口大小与注射器乳头相配。拔去塞子,将消毒注射器接上Y形管,轻轻抽吸即有尿液流入注射器内。这样收集的尿液直接取自于膀胱,尿液新鲜,最适于作尿培养。以往遇尿液引流不畅时,常拆开导尿管与引流管连接部,用注射器反复抽吸或冲洗,操作很不方便;多次拆卸还会增加感染机会。使用改进的引流装置后再不用拆开导尿 The incidence of urinary tract infection after indwelling catheterization is very high. We have created a drainage device for urinary tract that can effectively reduce the urinary tract infection. Insert a Y-shaped plastic pipe facing downward in the upper part of the draft tube (see picture). Y-shaped tube outside the mouth by a plug with a closed handle, nozzle size and syringe nipple match. Unplug the stopper, the sterile syringe connected to the Y-shaped tube, gently aspirate the urine into the syringe. Urine collected in this way is taken directly from the bladder and fresh urine is best suited for urinary culture. In the past case of poor drainage of urine, often open the catheter and drainage tube connection, with the syringe repeatedly suction or flushing, the operation is very inconvenient; multiple disassembly will increase the chance of infection. After using the improved drainage device without having to open catheterization
