WVM — the Five Rights, enforced in hardware.
Nurse biometric, ABHA wristband scan, locked bins. The right patient, drug, dose, route and time — verified at the bedside before a single cell unlocks.
Five Rights · Hardware lock
- Single bin unlocks per dose
- Right patient, drug, dose, route, time
- MAR auto-writes on close
The Five Rights, enforced in hardware. At the bedside. Every time.
The WVM (Ward Vending Machine) is BBB's ward-side hardware — a wall-mounted, biometric, ABHA-aware bin grid that sits between the pharmacy and the patient. No cell unlocks until the right nurse, the right patient wristband, the right drug, the right dose, the right route and the right time are all verified against the e-Rx. The Five Rights stop being a poster and become a hardware lock.
The five-step bedside flow
Nurse biometric
Fingerprint + HPR ID unlocks the WVM session for this nurse only.
Patient ABHA scan
Wristband QR pulls the active e-Rx and validates the patient identity.
Drug + dose verify
WVM checks the cell against the prescribed drug, dose and route — wrong drug, no unlock.
Time window
Cell unlocks only inside the prescribed administration window. Late or early = blocked + logged.
Bedside confirm
Second ABHA scan at the bedside writes the MAR entry and fires the NHA ₹5/Rx event.
Compliance & integration
- Five Rights enforced as a hardware interlock — not a checkbox
- Per-nurse, per-patient, per-dose audit trail
- ABHA wristband + MAR auto-write closes the loop
- Eliminates wrong-patient and wrong-time errors at the bin
