前臂靜脈操作方法
Operation method of forearm vein
1、一根綁在肘關節處，另一根綁在腕關節下，在前臂的背側可以看到靛藍色的靜脈，見下圖箭頭所示。用右手食指橫向來回觸摸皮下若隱若現的靜脈，能感覺到靜脈的彈性。
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、選擇走向相對來說比較直的一段靜脈進行穿刺，穿刺時要考慮到進針后導管固定的方向和對患者活動的影響。見回血后松開止血帶，用透明敷貼固定留置針
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
