| An assistant pulls the arm on the venipuncture side towards the caudal, making sure that the patient does not become tense. |
| When venipuncture has been successfully carried out, the flow of blood can be seen through the translucent Luer adapter of the holder. |
| The arm should be placed on the cushion so that the area for venipuncture is hyperextended. |
| With the transparent view window in the needle hub, blood flow is visible immediately on correct venipuncture. |
