Specify blood-component storage and transport with qualified temperature performance, monitoring, alarms and a documented power-failure response.
Medical equipment RFQ checklist (TXT)
Blood-component quality depends on controlled storage and transport with an effective response to excursions. Equipment selection should cover performance, monitoring, alarms, staff responsibility and continuity together.
Each component has its own storage condition, and they are not compatible with one another, which is why a blood bank needs several pieces of temperature controlled equipment rather than one large refrigerator.
Different blood components require different validated storage conditions. Conventional red-cell refrigeration, frozen-plasma storage and platelet storage are not interchangeable; specialised approaches such as cryopreservation or cold-stored platelets require an approved programme. The transfusion service must define the conditions and allowable excursions for each component.
Take the exact figures from the standard your service works to under the national safe blood transfusion programme rather than from a supplier brochure, and print them on the cabinet door. Staff should not have to remember which door holds which band.
Select refrigeration qualified for the intended blood component and storage conditions. A domestic food refrigerator’s temperature behaviour, monitoring and alarm design should not be assumed to meet those requirements.
Specify a refrigerator qualified for blood storage over its intended load and ambient range, with reliable temperature control and alarms. Automatic defrost is not inherently disqualifying: its operation must keep stored components within the validated limits. Verify mapping, recovery after door openings and sensor arrangements for the offered model.
Visible appearance cannot confirm that a component remained within its permitted conditions. The storage equipment and records need to support the transfusion service’s release and investigation procedures.
The monitoring plan should address measurement, records and an alarm response appropriate to the stored components.
Choose monitoring and alarm arrangements using the manufacturer’s qualified configuration and the transfusion service’s procedure. Sensor location and any thermal buffer should reflect temperature mapping and the monitoring objective. A display reading alone does not show the temperature history of every stored unit.
Use the required continuous recording and independent checks under the approved monitoring plan. Periodic spot readings alone cannot establish that no excursion occurred between them.
Alarms must reach staff authorised and able to respond. Test the notification route and backup arrangements under the approved procedure, including loss of mains power or communications.
During an interruption, follow the documented cold-chain contingency plan and minimise door openings. Use only a qualified loading pattern; any ballast must be approved for the refrigerator and must not obstruct airflow or reduce usable capacity unexpectedly. Transfer decisions require the component’s recorded conditions and the responsible transfusion team.
Confirm refrigerator restart behaviour and recovery after a power interruption from the manufacturer. Qualified electrical staff should select any protection or backup needed for the actual site; a stabiliser is not a universal answer to all interruptions.
Check the refrigerator’s specified ambient operating range against the room’s measured conditions, including loss of air conditioning. Evaluate refrigeration power, alarm power and any essential room cooling separately in the backup plan. Test the plan under controlled conditions before relying on it.
The cold chain does not end at the cabinet door. Units travel to theatre, to the ward and sometimes to another hospital, and each of those journeys either preserves the band or does not.
Qualify transport containers and packing arrangements for the component, route, duration and credible ambient conditions. Use an approved test protocol and suitable monitoring; a supplier’s generic holding-time figure may not represent the intended journey.
Return-to-stock and disposition decisions belong to the transfusion service’s approved component-specific procedure. Keep issue, transport, temperature and return records; do not infer acceptability simply because a returned bag feels cold.
Processing and thawing equipment must be qualified for the intended blood-component procedure. A general laboratory centrifuge or water bath is not automatically suitable: confirm the required rotor, controls, containment, temperature performance and validation with the transfusion service before including it in the equipment schedule.
For donation furniture, confirm the safe working load, access, cleaning and clinically required positioning with the donation team. Assess the complete chair or couch configuration and emergency access instead of selecting by appearance alone.
If the service uses irradiated blood components, irradiation and release require a validated programme and appropriate records. A radiation-sensitive indicator label helps identify exposure status; it does not measure the absorbed dose or replace dosimetry and release checks.
The transfusion service should use current applicable requirements and manufacturer instructions alongside established cold-chain guidance. Reference: WHO manual on blood cold-chain equipment.
