Instructions
1. Inject heparinized normal saline into the guide wire protection coil with a syringe to fill the guide wire protection coil so as to wet the guide wire coating.
2. Push the exposed part of the guide wire, take out the guide wire from the coil until the head end of the guide wire is exposed from one end of the protective coil, and gently take the head end of the guide wire out of the protective coil. Avoid damage to the tip of the guide wire. When taking the guide wire out of the coil, do not grasp the tip of the guide wire. If the guide wire cannot be easily removed from the guide wire protection coil, inject some heparinized normal saline into the guide wire protection coil and try again.
3. Once the guide wire has been taken out, do not put it back into the coil or reuse it.
4. Carefully shape the guide wire head end with standard shaping as required. Do not use shaping needles with sharp edges.
5. Before use, heparinized normal saline is injected into the used catheter to ensure that the guide wire can move smoothly in the catheter.
6. Carefully insert the guide wire into the interventional instrument through the guide wire cavity, and carefully push the guide wire to make the distal end of the guide wire reach near the distal end of the interventional instrument.
