笔者用一次性使用输血器制作双腔引流管，效果良好，制作简单，便于推广应用。现简要介绍如下。1输血器的构造见图1。2制作过程将输血器下段的细管拔下，剪去针头，形成一细橡胶管（图2，a），将莫菲氏管下段的一部分剪下．形成1个较粗的橡胶管（图2，b图3双腔引流管在粗管侧壁 The author uses a one-time use of a blood transfusion device to produce a double-lumen drainage tube, which has a good effect, is simple to produce, and is convenient for popularization and application. The brief introduction is as follows. 1 The structure of the blood transfusion device is shown in Fig. 1. 2 During the production process, the lower tube of the blood transfusion device is pulled out, the needle is cut off, and a thin rubber tube is formed (Fig. 2, a), and the lower part of the Murphy tube is cut off. Form a thicker rubber tube (Figure 2, b Figure 3 Double-cavity drainage tube on the side of the thick tube
