1. Unpack: Make sure the packaging is intact before use. Gently tear open the packaging to avoid damaging the needle or contaminating it.
2. Disinfection: Disinfect the patient’s blood collection site before use to ensure the sterility of the collected blood samples.
3. Select the appropriate needle specification: Select the appropriate needle specification based on the patient’s age, body shape, and characteristics of the blood collection site. In general, children and thin patients may choose smaller needles, while muscular adults may require larger needles.
4. Blood collection: Insert the needle into the patient’s skin and blood vessels at an appropriate angle and depth. Once the needle is in the blood vessel, a blood sample can begin to be collected. Pay attention to maintaining a steady hand grip and appropriate blood collection speed to avoid pain or blood clotting.
5. Collection completed: After collecting enough blood samples, gently pull out the needle. Use a cotton ball or bandage to apply gentle pressure to the blood collection site to stop bleeding and reduce the possibility of bruising.
6. Disposal of waste: Place used disposable blood collection needles and steel needles into special waste containers and dispose of them in accordance with medical waste disposal regulations.
