Kino VHP Disinfection Robot

Developed by Shanghai Dongfulong Medical Equipment Co., Ltd., a subsidiary of Tofflon, the Kino VHP Disinfection Robot represents China’s first intelligent vaporized hydrogen peroxide (VHP) disinfection system. The platform uses proprietary flash evaporation technology to achieve rapid, full-area space sterilization with 6-log microbial reduction capability.

Product Overview

The Kino series addresses the critical need for effective, residue-free space disinfection in healthcare and pharmaceutical environments. Unlike traditional disinfection methods that may leave chemical residues or require extended downtime, VHP technology decomposes into water and oxygen after the sterilization cycle, enabling rapid room turnover without surface wiping or ventilation requirements.

The system gained prominence during the COVID-19 pandemic when multiple units were deployed to frontline hospitals in Wuhan, demonstrating its effectiveness in high-risk infectious disease control scenarios.

Key Features

Designed for terminal hospital and pharmaceutical cleanroom disinfection, the Kino VHP robot uses 35% hydrogen peroxide flash evaporation to achieve 6-log microbial reduction with no toxic residues remaining after decomposition.

• Flash Evaporation Technology: Proprietary evaporation system rapidly generates high-temperature hydrogen peroxide vapor for efficient space saturation
• 6-Log Reduction: Achieves sterilization assurance level (SAL) of 10⁻⁶ against bacteria, spores, fungi, mold, and viruses
• Broad-Spectrum Efficacy: Effective against a wide range of microorganisms including resistant bacterial spores
• No Residue: Hydrogen peroxide decomposes to water vapor and oxygen, leaving no toxic residues
• Intelligent Control: Automated cycle management with real-time concentration monitoring
• Mobile Platform: Self-contained unit designed for movement between treatment areas

Technical Specifications

Designed for operating rooms, ICUs, and pharmaceutical cleanrooms, the Kino mobile platform vaporizes 35% hydrogen peroxide through intelligent automated cycling to achieve 6-log reduction against bacteria, spores, fungi, mold, and viruses.

Mechanism of Action

The Kino system operates through a multi-phase sterilization cycle:

1. Vaporization Phase: High-temperature flash evaporation converts liquid hydrogen peroxide into saturated vapor
2. Distribution Phase: Vapor is continuously released until the enclosed space reaches saturation
3. Contact Phase: Saturated vapor contacts cooler surfaces, forming micrometer-scale condensation layers around microorganisms
4. Oxidation Phase: Hydrogen peroxide molecules react with light or metal ions to release highly oxidative hydroxyl free radicals
5. Inactivation Phase: Free radicals attack cell membranes and DNA, causing rapid microorganism inactivation
6. Decomposition Phase: Residual hydrogen peroxide degrades into water and oxygen

The company also provided units for the Hong Kong MTR disinfection program, demonstrating the system’s adaptability to public transit applications.

Frequently Asked Questions

What spaces can the Kino disinfection robot sterilize?

The Kino VHP disinfection robot is designed for enclosed spaces including hospital rooms, operating theaters, ICUs, pharmaceutical cleanrooms, laboratories, and isolation facilities. The system requires the target space to be sealed during the sterilization cycle to maintain hydrogen peroxide vapor concentration.

How long does a disinfection cycle take?

Cycle duration varies based on room volume, target sterilization level, and environmental conditions. A typical hospital room disinfection cycle, including vaporization, exposure, and aeration phases, generally requires 2-4 hours for complete 6-log reduction.

Is VHP disinfection safe for sensitive equipment?

VHP is generally compatible with most hospital and laboratory equipment, including electronics and sensitive instruments. The low-temperature process and absence of liquid residue make it suitable for environments containing sensitive medical devices. However, specific material compatibility should be verified for critical applications.
