Storage, cold-chain monitoring, end-to-end traceability, and stock alerts that protect blood quality and supply
The smart blood-bank solution is for blood centers, blood stations, and hospital transfusion departments. Using IoT, it monitors temperature and humidity and traces blood from collection and testing through storage and issue. Storage limits are strict: whole blood at 2–6°C, platelets at 20–24°C with agitation, and plasma at −20°C. Handwritten logs and paper ledgers slip. Four modules raise quality control: temperature monitoring, blood-bag management, end-to-end traceability, and stock alerts.
Temperature monitoring watches fridge temperature and humidity around the clock and alarms on exceptions. Blood-bag management uses RFID for the life of each bag. End-to-end traceability follows a unit from collection to clinical use. Stock alerts fire when inventory runs low. Together they meet the safety and traceability duties of blood centers, stations, and hospital transfusion departments, and they can connect to systems already in place, including HIS and the blood-bank system, for quality control from end to end.
The Blood Donation Law of the People's Republic of China and the Measures for the Administration of Blood Stations set clear duties for storage, transport, and traceability. Whole blood is held at 2–6°C, platelets at 20–24°C with agitation, and plasma frozen at −20°C. A temperature failure can mean the unit is discarded. Blood centers need live monitoring around the clock, with alerts at more than one level, and a trail from collection to clinical use that satisfies quality management. Refrigerated vehicles and transport boxes need temperature monitoring. 4G/NB-IoT carries the data, and RFID readers manage the bags.
SimtoLink supplies 4G/NB-IoT IoT SIMs, data pools, and private APNs, with APIs into systems such as HIS and the blood-bank system, so monitoring stays reliable around the clock.
Blood stations and centers should start with wired plus 4G dual-link backup, temperature-monitored transport boxes, and 4G/NB-IoT temperature devices on refrigerated vehicles. Temperature and humidity go to the cloud as they change, which supports management rules such as GSP. When you connect the information system, confirm the data format, the alarms, and the trace chain. Keep a round-the-clock duty roster, and send multi-level temperature alarms to the people on duty.
Management across the life of a blood unit
Fridge temperature and humidity are watched around the clock, including the 2–6°C zone for whole blood and −20°C for plasma, with a log of exceptions. That supports rules such as GSP.
RFID follows each bag through receipt, storage, issue, and clinical use, with blood type, expiry, and temperature on the record.
A scan shows where a unit came from, its temperature record, and its transport path, from collection to clinical use, which is what quality traceability asks for.
Low stock raises an alert on its own, graded by blood type and expiry, so purchasing and clinical issue can be planned.

A smart blood bank uses temperature sensors, RFID readers, fridges, and transport boxes, over 4G and NB-IoT. SimtoLink supplies 4G/NB-IoT IoT SIMs, a data pool, and APIs into systems such as HIS and the blood-bank system, so monitoring stays steady around the clock and quality control runs from collection to issue.
