Medical Application Scenario
Providing Sterile Assurance for Daily Water Use in Low-Immunity Patients
Key Challenges
Water Safety Challenges for Immunocompromised Patients
Zero Tolerance for Microbial Infection Risks
Bone marrow transplant patients are in an "immune blank period" for 100 days post-surgery, where opportunistic pathogens like Pseudomonas aeruginosa and Stenotrophomonas maltophilia in water can invade the body through drinking, mouth rinsing, skin cleaning (e.g., wipe baths), causing infections with mortality rates up to 40%-60%, one of the main causes of non-relapse deaths in bone marrow transplant patients.
Difficult Biofilm Removal in Water Supply Systems
Inner walls of water supply pipelines easily form biofilms (protective structures formed by bacterial aggregation); traditional chemical disinfection only kills surface bacteria, cannot penetrate biofilms, and drug-resistant bacteria persist.
Solution
Full-Process UVC Sterilization, Blocking Pollution at the Source
Physical sterilization leaves no residue, providing comprehensive sterile water assurance for immunocompromised patients across all scenarios.
Terminal Daily Drinking Water
Integrate small UV-C disinfection modules at ward water dispenser outlets and public area direct drinking machine faucets, forming a "disinfect upon output" closed loop. Built-in water flow sensors enable "automatic start when water is taken, shut off when stopped" to avoid unnecessary energy consumption.
Terminal Medical Care
Integrate disinfection modules at shower heads and washbasin faucets; provide sterile daily water for patients.
