อะไรคือ 3 Stages Of Autoclave Sterilization?
According to AAMI standards, steam sterilization is one of the most reliable methods for medical device reprocessing. Whether using a gravity or pre-vacuum cycle, all validated autoclave sterilization processes consist of three fundamental phases.
This is the most crucial step. Air is removed from the chamber and items are heated. Any trapped air acts as a barrier, preventing the ฆ่าเชื้อ (steam) from contacting the surfaces of the load.
The load is maintained at a specific set temperature (เช่น, 121°C or 134°C) for a predetermined duration. This ensures the total inactivation of microorganisms.
Steam is extracted from the autoclave chamber. The load undergoes a drying process to prevent moisture-related recontamination of the sterile instruments.
Gravity vs. Pre-vacuum Cycles
While both methods provide effective การทำหมัน, they differ significantly in their approach to the “เครื่องปรับอากาศ” phase:
| Feature | Gravity Cycle | Pre-vacuum Cycle |
|---|---|---|
| Air Removal | Passive (Steam displaces heavier air) | Active (Mechanical vacuum pump) |
| ประสิทธิภาพ | Lower; requires longer exposure | Higher; rapid air removal |
| ดีที่สุดสำหรับ | Simple, non-porous items | Complex instruments with lumens |
| AAMI Class | Gravity Displacement | Dynamic Air Removal |
Why Choose BOCON Sterilization Solutions?
While Autoclaves are excellent for heat-stable items, many modern medical devices are heat-sensitive. BOCON specializes in เอทิลีนออกไซด์ (อีโอ) Sterilizers, which provide a low-temperature alternative to autoclave sterilization. ของเรา บีซีเอส ซีรีส์ ensures that your most complex, moisture-sensitive devices achieve the same high sterility assurance levels without the risks associated with high-pressure steam.
