Home Physics Plasma Sterilizer for Cold Sterilization of the Medical Items and Materials.

Plasma Sterilizer for Cold Sterilization of the Medical Items and Materials.

Description

The sterilizer generates dense and highly uniform plasma which is particularly suitable for fast and efficient sterilization of medical instruments, especially those with canals and deep holes.

Sterilization process includes the two repetitive treatment stages. During the "steam' stage chemical steam (H2 02 ) is injected into the vacuum-processed camera with medical instruments. Highly efficient penetration of steam into packets and hard-to-reach places is performed by a dedicated injection/evaporation system. After the "steam" stage the camera is vacuumized again, which is followed by glow-discharge plasma treatment stage.

Features:

  • Overall dimensions:........................810 x 620 x 1510mm
  • Camera size: .............................. Depth: 650 mm; Diameter: 450 mm
  • Camera material:...........................Stainless steel
  • Net weight:....................................275 kg
  • Operating conditions:.....................T=10-43 °C; relative humidity ≥ 80%; Atmospheric pressure 600-800 mmHG
  • Energy consumption:.....................Average - 500 W; Peak - 1100 W
  • Automatic control system:.............Based on 80c31 microcontroller, audible indication

Sterilization capacity:

  • Maximum temperature of instruments under sterilization:.... > 60°C
  • Processing time (from loading to unloading):......................15-45min
  • Sterilization time:
    • open surface of packed instruments:.......................... > 5 min
    • instruments with closed holes:.................................. 30 min

Innovative Aspect and Main Advantages

The sterilizer uses innovative highly efficient electric discharge for generation of active species, which perform sterilizing action during the discharge operation, and immediately after the discharge turning oft" are converted to safe substances without toxic residuals.

The sterilizer is proved to be more efficient (up to 100%) comparing with the conventional sterilizers (12/88 on ethylene oxyde) and other types of plasma sterilizers (Sterrad 100, Advanced Sterilization Products; Plazlyte Sterilization System, model ABT 1.0, Abtox Inc.).

Plasma sterilization technology is approved by the Ministry of Health of Ukraine.

Areas of Application

  1. Sterilization of heat-sensitive medical instruments (processing temperature does not exceed 60o C).
  2. Rapid sterilization of medical instruments (the instruments can be used immediately after the treatment).
  3. Sterilization of different medical instruments, including those with long narrow channels, placed inside special package for safe storage of the instruments before their use.

Stage of Development

The prototype of the sterilizer is designed, elaborated and successfully passed medical-biological tests with the use of variety of actual medical instruments.

Developer: Department of Gas electronics of the Institute of Physics (Tsiolko V.V.)

Hey there this is kinda of off topic but I
was wondering if blogs use WYSIWYG editors or if you have
to manually code with HTML. I'm starting a blog
soon but have no coding skills so I wanted to get guidance
from someone with experience. Any help would be greatly appreciated!
