Hemovigilance Traceability Ledger

Trace every unit.
From donor to patient.

Track each blood unit from donor collection through storage to the patient it was transfused into, on one traceable record. When a transfusion issue surfaces, the donor and every co-donation recipient are identified in minutes instead of a slow search across separate systems.

The Foundation

The Execution Mechanics

Unite donor records, storage conditions, and transfusion outcomes into one traceable chain.

01.

Unit-Level Traceability

The Traceability Ledger anchors each blood unit from collection to transfusion, so a single unit's full journey is one query rather than a search across donor and patient systems.

02.

Cold-Chain Monitoring

The Cold-Chain Monitoring module logs storage temperature for every unit, flagging any excursion that could compromise a component before it is issued.

03.

Recall Isolation

The Quality and Recall Ledger links a flagged donation to every unit and recipient from the same batch, so a safety issue is contained precisely and fast.

04.

Donor-Batch Linking

Each unit carries an immutable link to its donation and donor, so tracing a suspect unit back to its source and co-donations is instant.

05.

Component Split Tracking

When a donation is split into components, each derivative inherits the traceable link, keeping plasma, platelets, and red cells all bound to the origin.

06.

Hemovigilance Query

A blood safety officer traces any unit or donor in one view, replacing a manual reconciliation of collection and transfusion logs with a live query.

The Blood Unit Lifecycle

Follow one donation from collection through cold storage to transfusion and a rapid safety trace.

Smart Contract Anatomy

Cerulea decomposes blood traceability into modular contracts. Each layer collects, monitors, transfuses, and traces without donor and patient records living in separate silos.

Applicability Across the Spectrum

Donor-to-patient traceability is a horizontal capability. Here is how different actors in transfusion care put it to work.

Blood Banks

Track every unit from collection through split components to issue, so inventory and traceability live in one record instead of separate donor and stock systems.

Key Asset Types

  1. 1Blood Units
  2. 2Component Splits
  3. 3Storage Logs

Transfusion Services

Bind each transfused unit to its recipient and confirm cold-chain integrity before issue, so any adverse reaction can be traced to a specific donation immediately.

Key Asset Types

  1. 1Transfusion Records
  2. 2Recipient Links
  3. 3Excursion Flags

Blood Safety Authorities

Run a hemovigilance lookback across the whole network in one query, identifying every recipient of a suspect donation without contacting each facility separately.

Key Asset Types

  1. 1Lookback Trails
  2. 2Recall Records
  3. 3Safety Registries

Network & Execution Architecture

Whether you are bridging blood bank inventory systems or capturing storage telemetry from cold-chain sensors, Cerulea routes both into one traceable record.

Track A: Blood Bank System Bridging

For blood banks on legacy inventory platforms. Collection, issue, and transfusion events are translated into signed on-chain unit transitions through the API gateway.

Track B: Cold-Chain Sensor Capture

For storage units with connected sensors. Temperature readings are signed by the device and routed directly to the ledger, flagging excursions in real time.

Technical Methodology

The legacy timeline reflects blood service integration benchmarks. Wiring inventory and transfusion systems, building cold-chain monitoring, and shipping a lookback trace for an average network takes a baseline of 8 months. Building the same architecture on Cerulea takes a baseline of 2 weeks, because Cerulea Studio visually translates your traceability and recall rules into pre-audited WebAssembly binaries and provisions the hemovigilance ledger instantly.
