1, choose blood vessels: choose the blood vessels of the upper limbs, such as the back of the hand, wrist, forearm and so on, in order to facilitate the lancing.
2, disinfecting the skin: use a disinfectant swab or alcohol to disinfect the lancing site.
3, hold the needle: hold the handle of the syringe with the thumb and index finger to ensure that the needle is fixed.
4. Sticking the needle: Insert the needle into the blood vessel at a certain angle, an angle of 15-30 degrees is generally recommended. If the blood vessels are harder to find, you can make them more visible by gently tapping or massaging them.
5. Fixing the needle: After successful lancing, use tape or other fixation to hold the needle in place to prevent it from moving.
6. Adjusting the infusion rate: Adjust the infusion rate as needed and ensure the safety of the infusion process.
