STAT Dispatch Target
Built on four clinical principles.
Traditional blood coordination in Bangladesh is fractured across social media noise and predatory brokers. BloodOS replaces chaos with clinical reliability.
Automated 56-Day Rest
Our algorithm locks donor eligibility after whole blood donation, preventing premature draws and guarding volunteers against chronic anemia.
Privacy Phone Masking
Contact numbers are masked (01XXX***XXX) on public views to stop broker databases and nuisance calls.
64-District Local Grid
Transfusion alerts target donors within the patient's specific district, slashing transit delays during code-red operating room emergencies.
Zero Commercial Fees
BloodOS is 100% voluntary. We strictly ban any commercial exchange, middlemen commissions, or payment gateways for blood units.
How emergency blood coordination works.
From hospital requisition to bedside transfusion in 4 systematic stages.
Post Urgent Request
Patient relative or coordinator inputs blood group, hospital, required units, and urgency level.
Targeted Donor Alert
BloodOS matches ABO/Rh compatibility and filters for verified donors in the district who are past their 56-day rest.
1-Tap Response
Eligible donor taps “I Can Help”. Contact is unlocked directly between donor and coordinator with zero brokers.
Fulfilled & Safe Rest
Request status marks fulfilled. Donor's 56-day cooldown timer starts immediately to protect biological recovery.
