De Novo xGrid™

The Last Line of Defense When the Grid Goes Down

Imagine this:

Earthquake strikes. Cell towers collapse. Power and communications gone. How does the surgeon access emergency patient records? What's the emergency transfusion protocol? How long can oxygen and backup power last?

How does the shelter maintain volunteer operations? How to register and triage? How to coordinate emergency supplies? How to handoff patient transfers? How does the pharmacist dispense medications?

With power and network completely down, how does the command center know real-time status of personnel, supplies, and equipment to coordinate, request aid, and evacuate?

No need to go back to all-paper era. De Novo xGrid keeps everything running offline — medical data instantly accessible, ensuring every minute counts for saving lives.

When Disaster Strikes

Earthquake, typhoon, battlefield — when the network goes down, xGrid is the last line of defense.

Network Down

Earthquake collapses cell towers. Typhoon cuts fiber lines. Cloud services become unreachable — but patients still need care.

Equipment Damaged

Flooding, lightning, shelling — when equipment is damaged and data becomes inaccessible, you need a system that already lives on every device.

Field Operations

Remote disaster sites, mobile clinics, forward operating bases — no stable network, but nurses can run the full patient workflow from a phone.

De Novo xGrid: Built for the Worst

An offline-first medical platform on a credit-card-sized Raspberry Pi. Nurses operate the full patient workflow from their phones — registration, triage, surgery, transfusion, discharge billing. Sync when connected, operate independently when not.

Architecture Validation

Built for Real Disasters

Designed with input from emergency responders and medical professionals

Walkaway Test

If the dev team dissolves and servers shut down, can the system keep running? We validate with 5 tests.

Lifeboat Protocol

When the hub fails, edge devices can rebuild the system.

Disaster Strikes

Replace Hub

One-Click Restore

Like a starfish regenerating a limb, every De Novo xGrid edge device can rebuild the central brain.

When designing a system, assume you'll be hit by a bus tomorrow. Can your users continue without you? This is our standard for every line of code.

System Validationv7.9.1 · Feb 2026

149-Step Automated Test — 10 Patient Scenarios

The most demanding test: 3 of 8 medical stations forced to evacuate simultaneously — with active blood transfusions and an ongoing surgery. The system ensured every patient record, blood bag, and medication transfer was tracked and verified, without interrupting care.

What is a PWA?

A website that installs like an app. No app store needed — just visit and add to your home screen.

How Does It Work?

PWAs cache everything locally. Once installed, the app runs from your device, even without internet.

Why Does It Matter?

In disasters, networks fail first. PWAs keep working when you need them most — offline, reliable, instant.

Event Bus

Real-time cross-tab synchronization. When a nurse updates a patient status, doctors see it instantly.

Unified API

Standardized communication protocol with automatic retry, timeout handling, and error recovery.

Offline Queue

Operations continue seamlessly without internet. Data syncs automatically when connection returns.
