Cleaning, Sterilization, and Disinfection

6.8K
Cleaning, disinfection, and sterilization are the methods that help to break the infection chain and prevent disease.
Cleaning
The cleaning process usually involves using water with detergents or enzymatic cleaner and removing foreign material from objects and surfaces, including organic material such as body fluids or inorganic material like soil. Cleaning is performed before high-level disinfection and sterilization because foreign materials on the cover of the devices interfere with process...

Hand hygiene

3.2K
Asepsis is the practice of preventing or breaking the chain of infection. The nurse employs aseptic techniques to prevent the spread of microorganisms and reduce the risk of diseases. Hand hygiene is the cornerstone of aseptic techniques and is classified into medical and surgical asepsis. Medical asepsis includes hand hygiene and the use of gloves. Surgical asepsis, or the sterile technique, refers to practices that render and keep objects and areas free of microorganisms.

Area of Science:

  • Robotics
  • Environmental Science
  • Microbiology

Background:

  • Current disinfection robots face challenges like secondary pollution, incomplete coverage, and low efficiency.
  • Autonomous mobile disinfection systems are needed to overcome these limitations.

Purpose of the Study:

  • To propose and evaluate an autonomous mobile combination disinfection system using ultraviolet (UV) radiation and hydrogen peroxide aerosol.
  • To address secondary pollution, disinfection dead corners, and low efficiency associated with conventional disinfection methods.

Main Methods:

  • Development of an autonomous mobile combination disinfection system with a human-computer interface, mobile robot, and disinfection equipment.
  • Establishment of a disinfection process model featuring continuous and fixed-point modes.
  • Quantitative calculation of effective disinfection range, speed, and duration.

Main Results:

  • The combined system achieved a 92.95% disinfection rate of airborne bacteria in a 22m² room within 30 minutes.
  • Disinfection efficiency was at least 25% higher than standalone UV lamp disinfection.
  • Noticeable improvement in efficiency was observed compared to standalone hydrogen peroxide aerosol disinfection.

Conclusions:

  • The proposed system offers an environmentally friendly, rapid, efficient, and all-encompassing solution for airborne bacterial disinfection.
  • The autonomous mobile combination disinfection system effectively overcomes the drawbacks of current disinfection robots.
  • Recommendations for various disinfection solutions and applications are provided.
