Introductions for use
1. Remove the protective coil with the guidewire from the package together. Do not use if the package is found to be opened or broken.    
2. Attach a syringe containing heparinized saline to the luer seat of the guidewire protection coil and inject it into the protective coil of the guidewire so that it fills the protective coil to moisten the guidewire.      
3. Remove the guidewire from the coil by pushing the exposed distal end of the guidewire until the proximal end of the guidewire is removed from the protective coil. When removing the guide wire from the coil, avoid gripping the head end of the guide wire to prevent damage to the wire. If the guidewire cannot be easily removed from the protective coil, re-inject an appropriate amount of heparinized saline into the protective coil and retry.    
4. Once the guidewire has been removed, do not reinsert it into the coil or reuse it.
5. Before use, inject heparinized saline into the catheter used to ensure that the guidewire can move smoothly through the catheter.
6. Carefully insert the distal cephalic end of the guidewire.
7. Advance the guidewire to the target site while keeping the catheter position fixed under x-ray fluoroscopy.
Note: Observe the movement of the guidewire within the vessel under X-ray fluoroscopy. Advance the guidewire only if the tip of the guidewire is visible under X-ray. During the operation, if resistance is felt or obstruction is detected by X-ray fluoroscopy, determine the cause and take appropriate measures to eliminate the resistance and avoid the risk of vascular perforation by carefully and slowly advancing or retracting the guidewire.
8. After positioning the guidewire safely, the treatment instrument is advanced to the target site.
9. The guidewire is withdrawn under the protection of the catheter.

Storage and transportation conditions
Store the product at room temperature, in a clean, well-ventilated environment without corrosive gases, avoid direct sunlight, and avoid storage in abnormal temperature and high humidity.
