After Treatment Maintenance
Clean the Sapphire Treatment Window
The sapphire tip is one of the most important parts of a diode laser handpiece.
After each session:
- Remove gel residue
- Clean the surface with an approved method
- Use soft, lint-free materials
- Avoid abrasive cleaning products
A clean sapphire window helps maintain efficient energy delivery.
Clean the Handpiece and Exterior
Use:
- Soft cloth
- Approved cleaning solution
Avoid:
- Excessive moisture
- Strong chemicals
- Immersing components in liquid
Record Equipment Performance
Professional users should keep basic records:
- Treatment parameters
- Error messages
- Unusual sounds or behavior
- Service history
This helps identify changes in performance over time.
Weekly Maintenance Checklist
Weekly inspections help prevent small issues from becoming larger problems.
Inspect Cables and Connections
Check:
- Loose connections
- Cable damage
- Signs of wear
Damaged cables should be inspected by qualified technicians.
Clean Optical Areas
Depending on the device design:
- Clean accessible optical surfaces
- Remove dust or residue
- Check for contamination
Always follow manufacturer recommendations.
Check Cooling System
For water-cooled diode laser systems:
Check:
- Coolant level
- Water circulation
- Temperature warnings
Use only recommended coolant types.
Do not use tap water unless specifically approved by the manufacturer.
