1. Take out the indwelling needle from the package.

2. Hold the indwelling needle catheter seat and needle tube seat with your thumb and index finger, rotate to loosen and remove the protective cover. Note: When removing the protective cover, avoid holding only the needle tube socket to prevent pulling out the catheter with excessive force.

3. The indwelling needle in the right hand is slowly pierced into the skin and blood vessels at an angle of 15-30 degrees.

4. Insert the needle 2mm parallel to the skin. After the transparent needle seat of the indwelling needle sees blood return, reduce the angle of the indwelling needle to be basically parallel to the skin and then insert the needle 2mm.

5. Withdraw the needle tube 0.5-1cm from the catheter. If there is a large amount of returned blood in the catheter, send the remaining catheter into the blood vessel. Note: The needle should not be drawn back from the catheter too much. When the catheter enters the blood vessel, the needle should be used for traction to prevent the catheter from being broken.

6. Loosen the latex tube clamped by the hemostatic forceps, pull out the needle tube seat, and tighten the heparin cap.

7. Bundle the paper tape to fix the indwelling needle.
