Operating room disinfection efficiency bottleneck
Customer pain points:
XXX Hospital's neurosurgery operating room uses hydrogen peroxide (H₂O₂) fumigation disinfection. The traditional process has three major problems:
Long waiting time after disinfection: H₂O₂ concentration needs to be reduced from 115ppm to a safe value of 1ppm, which takes 12-48 hours, and the
operating
room
utilization rate is less than 40%.
Chemical residue risk: Manual detection errors cause medical staff to be exposed to residual gas, causing an average of 5 cases of respiratory irritation per
year.
High energy consumption cost: The energy consumption of continuous ventilation in confined spaces accounts for 28% of the total electricity consumption of
the
operating
room.

Economic benefits:
Annual revenue increase: 1,728 units x average price of 32,000 = 55.3 million yuan.
Energy saving benefits: 26.2 kWh/time x 365 times x 1.2 yuan/kWh = 115,000 yuan/year.
Industry application expansion scenarios:
This solution can be quickly adapted to:
ICU air purification: combined with H14 high-efficiency filter (99.995% interception rate), reduce ventilator-related infection rate by 37%.
Nucleic acid testing station: positive pressure fresh air + double filtration (G4+H14), cleanliness reaches ISO 6 level (such as Haier Biomedical Solution).
Dialysis fluid preparation: hydrophobic PTFE filter element (0.1μm) ensures pyrogen-free dialysis water, complication risk ↓29%.
