How to use tabletop dental autoclave?

Here's a clear, step-by-step guide for using a tabletop dental autoclave:

1. Preparation of Instruments
Clean Thoroughly: Scrub all tools with detergent and water to remove debris before sterilization.
Rinse and Dry: Ensure no residue remains; pat instruments dry with lint-free cloths.
Package Correctly: Place instruments in sterilization pouches or wraps, leaving space between items.

2. Autoclave Setup
Fill Water Reservoir: Use distilled or demineralized water to prevent mineral buildup.
Load Chamber:
Arrange pouches/trays upright, not touching chamber walls or overlapping.
Avoid overloading; steam must circulate freely.
Secure Door: Close and latch tightly to maintain pressure.

3. Cycle Selection
Choose Appropriate Cycle:
Unwrapped Solids (e.g., forceps): Use "Gravity" or "N-Class" cycle.
Pouches/Hollow Tools (e.g., handpieces): Select "Pre-Vacuum" or "B-Class" cycle.
Porous Loads: Opt for "Steam-Flush Pressure Pulse" if available.
Start Cycle: Press the button; the autoclave will automate timing, temperature, and pressure.

4. Sterilization Process
Steam Penetration: High-pressure steam fills the chamber, killing microorganisms.
Timed Exposure: Instruments remain at high heat for the duration required.
Drying Phase: Hot air dries pouches/tools (if cycle includes drying).

5. Unloading & Storage
Wait for Completion: Do not open mid-cycle; allow automatic pressure release.
Cool Down: Let instruments sit inside for 5–10 minutes post-cycle to avoid burns.
Check Indicators:
Verify chemical strips on pouches changed color (e.g., stripes turn dark).
Inspect for moisture; wet packs are not sterile.
Store Properly: Keep sealed pouches in dry, covered drawers until use.

6. Weekly/Monthly Maintenance
Daily: Empty water reservoir; wipe chamber with a damp cloth.
Weekly: Run an empty cleaning cycle with autoclave detergent.
Monthly: Perform validation tests (e.g., spore tests) to confirm sterilization.
