QDAT.IO SPATIOTEMPORAL INTELLIGENCE AUTOMATION PLANE FOR BLOOD BAGS

Cooldat® and the Mass Transfer of Blood Products

Item-level cold-chain intelligence for safe, large-scale blood-product movement across regional health networks. Every unit carries its own temperature evidence — captured by an autonomous CoolTag and read with a handheld RFID reader running QDatDroid.

• •Item-level temperature logging on every unit
• •Handheld RFID scanning with QDatDroid
• •Predictive shelf-life ready data

THE CHALLENGE

Blood products are perishable, temperature-critical, and always in motion

A regional health network moves blood products constantly — between a central blood bank, hospital transfusion services, satellite clinics and operating rooms — through routine resupply, near-outdate redistribution, emergency surge transfers and returns to inventory. Every movement is a cold-chain risk, and each product class has a narrow, non-negotiable temperature window.

The CoolTag operates from −35 °C to +35 °C — one device covers frozen, refrigerated and room-temperature products. Thresholds shown are indicative; deployments are configured to the network's governing standards (e.g. Héma-Québec, Canadian Blood Services, AABB).

Blood-product outdating is the single largest contributor to blood wastage.¹ When the chain is broken — or simply cannot be proven intact — units are discarded. The "30-minute rule" tells staff when a red-cell unit can no longer be transfused, but it cannot tell a receiving facility whether a transferred unit's cold chain actually held. The result is conservative, wasteful decisions: one four-site Canadian redistribution program lost 23% of redistributed units to transport failures — chiefly temperature-storage failures² — a loss rate later cut to 2.8% once temperature-controlled transport containers were validated and standardized.¹ Mass transfer at regional scale is only as safe as the evidence that travels with each unit.

WHAT COOLDAT® DOES

It makes every unit self-documenting

Cooldat® turns each blood product into an object that records and reports its own cold-chain history. A peel-and-stick CoolTag — a battery-printed RAIN RFID logging label — rides with the unit and measures temperature continuously, from the moment it leaves controlled storage to the moment it is received. It runs autonomously for up to three months, holds up to 4,096 logs that stay retrievable even after the battery is depleted, and can report an alarm state without downloading the full log. At every checkpoint, a handheld RFID reader running QDatDroid scans the tag and streams its data to the cloud, where the platform builds a per-item temperature timeline.

FLAGSHIP EVIDENCE — TIME ABOVE SET-POINT

End-to-end excursion evidence attached to every unit

Per-item temperature history with min/max set-points, alarms, and out-of-range intervals captured across the full journey — from controlled storage to the receiving facility.

• •Per-item chart with min/max thresholds and highlighted excursions
• •Resolved-state alarms with trigger and resolution timestamps
• •Out-of-range intervals table: start, end, duration, and peak temperature

HOW THIS ENABLES MASS TRANSFER PROTOCOLS

Across the network, units move on evidence — not assumption

By making each unit's cold-chain status machine-readable, Cooldat® lets a network operate a shared, regional blood inventory — units re-accepted on evidence rather than assumption, and routed to where they are needed before they expire. The approach is proven at scale: one Canadian provincial program redistributed 15,499 near-outdate blood products across 130 hospitals over eight years, preventing roughly $17.6M CAD in discards.¹
