Unattended self‑service blood distribution refrigerator designed for hospitals, operating‑theatre blood‑holding areas, emergency departments, and transfusion wards that need 24/7, unsupervised storage and withdrawal of blood units. The cabinet acts as a local, autoriser‑free blood‑distribution node, accepting only electronically verified cross‑matched products, with a 4 °C ±1 °C internal temperature and 0.1 °C control accuracy, so units stay within international blood‑storage limits while enabling rapid, protocol‑aligned release to wards.
The HXC‑629ZZ model features a triple‑glass‑foam door with low‑emissivity (LOW‑E) coating, which cuts heat transfer and condensation in typical hospital environments (25 °C, 85 % humidity) while preserving clear visibility of bags inside. A microprocessor‑based controller with a high‑resolution touchscreen displays stock lists, access‑logs, removal‑reports, and alarms for high/low temperature, power‑failure, door‑ajar, sensor error, and low‑battery conditions, plus a remote‑alarm output that can trigger both audible buzzers and flashing lights. The inverter‑type compressor and optimised insulation structure deliver quick cooldown, low‑noise operation, and stable 4 °C performance, even in high‑traffic corridors, ICUs, and operating‑suite landings.
The unit integrates with a hospital‑wide blood‑management system so that, after electronic cross‑matching, authorised clinical areas are granted withdrawal privileges; nurses and doctors can then open the refrigerator unattended during the night or low‑staffing periods using an NFC access card or fingerprint‑reader, retrieving only pre‑assigned, ABO‑compatible units. A standard‑USB port exports detailed logs of temperature, door‑open events, removals, and inventory snapshots for up to ten years, and internal drawer or basket configurations simplify the physical organisation of 72 blood‑bags of 400 ml (HXC‑629ZZ), often combined with RFID‑tag reading for item‑level tracking of every unit.
Diferenciais
-
Unattended self‑service blood distribution refrigerator operating 24/7 with full traceability and user‑authenticating access.
-
Storage temperature 4 °C ±1 °C, with 0.1 °C temperature‑control accuracy.
-
HXC‑629ZZ model capacity: 72 blood‑bags of 400 ml, configurable as a mobile or wall‑mounted blood‑holding point.
-
Triple‑glass door with low‑emissivity (LOW‑E) film, reducing thermal‑bridge losses and condensation.
-
NFC‑card and optional fingerprint‑based authentication, leaving a digital audit trail of who removed which unit.

-
Inverter compressor for high energy‑efficiency, low noise, and reliable long‑term operation.
-
Standard USB interface for exporting temperature logs, door‑open records, removals, and inventory reports.
-
Internal drawer or basket options for neat organisation of 72 × 400 ml bags.
-
IoT‑linked inventory management that records date, time, user ID, and unit number for every withdrawal.
Aplicaciones
This unattended self‑service blood distribution refrigerator is ideal for general‑hospital settings, operating‑theatre satellite blood‑holds, emergency‑department blood‑bays, and ICU areas where “near‑zero” waiting time for transfusion products is required, especially outside daytime banking hours. By combining 4 °C storage, gate‑controlled access, pre‑validated compatibility checks, and detailed digital logging, the unit minimises transcription errors, incompatible‑transfusion risks, and product wastage, while supporting modern transfusion‑safety, quality‑management, and regulatory‑audit schemes.
The cabinet is also well‑suited to hospitals planning distributed‑blood‑node networks, placing these self‑service units on far‑from‑bank wards but still connected to the central inventory system, so nurses and doctors can withdraw only pre‑allocated, patient‑matched blood units, and all consumptions are recorded in a central monitor, improving blood‑utilisation governance, accountability, and clinical‑operational responsiveness
