前臂静脉操作方法
Operation method of forearm vein
1、一根绑在肘关节处，另一根绑在腕关节下，在前臂的背侧可以看到靛蓝色的静脉，见下图箭头所示。用右手食指横向来回触摸皮下若隐若现的静脉，能感觉到静脉的弹性。
1. One is tied at the elbow joint and the other is tied under the wrist joint. Indigo veins can be seen on the dorsal side of the forearm, as shown by the arrows in the figure below. Touch the hidden vein under the skin back and forth with the index finger of your right hand, and you can feel the elasticity of the vein.
2、选择走向相对来说比较直的一段静脉进行穿刺，穿刺时要考虑到进针后导管固定的方向和对患者活动的影响。见回血后松开止血带，用透明敷贴固定留置针
2. Select a relatively straight section of vein for puncture. The direction of catheter fixation after needle insertion and the impact on the patient's activities should be considered during puncture. Loosen the tourniquet after seeing the blood return, and fix the indwelling needle with transparent dressing
