Using a syringe piston correctly ensures the safety and accuracy of the injection. The specific steps are as follows:
1. Insert the syringe piston into the syringe barrel and rotate it appropriately to ensure a tight connection.
2. To inject the medication, pull the syringe piston outward to draw in the medication, then push the piston inward to inject the medication into the desired site.
3. Syringe pistons have a limited lifespan. To ensure accuracy and safety, it is recommended to use disposable syringes.
