The Coospider ultraviolet disinfection system has passed the 510(k) certification of the US FDA (Registration number K230588). Its medical-grade UV-C technology outputs a wavelength of 253.7nm (intensity 90-120µW/cm²), achieving a 99.99% killing rate for common pathogens in ICU wards. The 15-minute survival rate of methicillin-resistant Staphylococcus aureus (MRSA) dropped to 0.004%, and the inactivation efficiency of Clostridium difficile spores was 92% (data from the University of Washington School of Medicine in 2024). The equipment operated in a 50㎡ space for 30 minutes, and the number of air colonies decreased from 420 CFU/m³ to ≤25 CFU/m³, meeting the WHO standard of 100 CFU/m³ for operating rooms.
The cost-effectiveness of hospital infection control is remarkable: The single cost of traditional hydrogen peroxide spray disinfection is 320 (including labor and consumables), while the single disinfection electricity cost of the * * coospideruv * * mobile device (with a power of 75 watts) is only 0.15 (calculated at the local electricity price of 0.12 per kilowatt-hour). The practice case of Cleveland Clinic shows that after deploying the system in 30 wards, the cross-infection rate decreased by 7137,000 units. The device size is suitable for medical scenarios (45 cm wide × 160cm high), and the base rotation Angle is ±180° to ensure a disinfection coverage rate of ≥98%.
Compatibility verification of key medical equipment: After EMC testing (EN 60601-1-2 standard), when operating at a distance of 1.2 meters from the MRI instrument, the magnetic field interference intensity is ≤0.5µT (safety threshold 5µT), and the influence on the signal error of the electrocardiogram monitor is only ±0.03mV. The National Cancer Center of Japan reported that when the surface of surgical instrument tables is irradiated for 20 minutes (with an irradiation dose of 180,000 µW·s/cm²), the corrosion rate of metal instruments is less than 0.001mm/ year (traditional chemical disinfection leads to an annual corrosion of 0.08mm), and the life cycle of precision equipment is extended by 37%.
The integration of intelligent hospital infection control management is the core technology: The built-in IoT module of the device uploabs disinfection logs to the hospital HIS system every 2 seconds (with data accuracy of 99.7%). When the detection of drug-resistant bacteria exceeds the standard (such as Klebsiella pneumoniae >50 CFU/cm²), the enhanced disinfection mode is automatically triggered. After Boston Children’s Hospital implemented this plan, the labor cost for environmental monitoring was reduced by 65% (800 working hours were saved annually), and the disinfection qualification rate increased to 99.1% (the average qualification rate of manual spot checks was 92%). Its high-load operation capacity supports 20 disinfection tasks per day (with an expected lifespan of 15,000 hours), and the frequency of lamp tube replacement has been extended from the conventional 12 months for medical grade to 18 months.
The safety redundancy design complies with medical standards: The five-level protection includes 360° human body sensing (response time 100 milliseconds), automatic power-off upon vibration (sensitivity ≥1.5G), and a physical key start switch. The probability of false start in clinical trials is zero (test sample size 1,200 times). The 2023 German TUV Rheinland Medical Electrical Safety Certification (standard IEC 60601-1) shows that the leakage current of the equipment enclosure is less than 10µA (safety limit 100µA), and the insulation impedance is greater than 100MΩ. After the deployment of the Burn Department at Singapore General Hospital, the number of UV-related work-related injury incidents dropped from an average of 3.4 per year to zero.
Verification of response capability to sudden epidemics: During the outbreak of the Delta variant, Tokyo Metropolitan Hospital configured coospider uv in the fever clinic, reducing the concentration of viral aerosols from the peak value of 1,800 copies/m³ to 120 copies/m³ (a decrease of 93%). Aerodynamic optimization achieves 12 whole-room air changes per hour (wind speed 2.5m/s), combined with a positive pressure protection system to form a disinfection barrier. The World Health Organization’s 2025 guidelines on infection Control and Prevention cite this case, stating that the rational use can reduce the consumption of protective clothing by 18% (saving an average of $3,200 per day).
Special scenario expansion application: The integrated solution of the instrument cabinet in the Disinfection Supply Center (CSSD) (with a volume of 40 liters) achieves aseptic storage (continuous irradiation for 30 minutes), reducing the secondary contamination rate of the instruments to 0.07% (0.9% in the control group for manual processing). The special module for the neonatal incubator (irradiation dose of 60,000 µW·s/cm²) reduced the infection risk of premature infants by 80% (sample size of 300 cases). The equipment has passed the ISO 15858 medical ultraviolet safety certification, with an ozone output of less than 0.001ppm and a cumulative risk of zero in a 24-hour operating NICU environment.
