Freeze contact at the coolant face
Frozen gel packs or ice bricks can create a cold spot that does not appear in a center-only logger reading.
Red blood cell shipments need refrigerated control without freezing the component or pressing bags against hard coolant. The packout should protect the component, l'étiquette, the document set, and the temperature record at the same time.
Blood product shipments should be judged by temperature history and by receiving condition. The details below are packaging planning guidance; final handling must follow your facility procedure and local requirements.
Frozen gel packs or ice bricks can create a cold spot that does not appear in a center-only logger reading.
Door-open transfer, courier wait time, and receiving delay can lift the outer payload faster than expected.
Tight inserts, liquide de refroidissement lourd, or condensation can damage bags, étiquettes, and paperwork needed at receiving.
| État de l'itinéraire | Intention de température | Packaging setup | Coolant or dry ice planning | Réception du chèque |
|---|---|---|---|---|
| Controlled vehicle or short courier, 0-6 h | Maintain refrigerated handling and avoid freezing; align with the facility procedure for red cells. | Pre-conditioned insulated medical shipper, doublure absorbante, bag cradle, one logger near payload, coolant separated by divider. | Often no frozen coolant against payload. Pour un 3-8 L parcel, test 0.8-1.5 kg conditioned 2-8 C gel or PCM behind a barrier. | Courbe de température, no cold marks, dry label, bag support, and handoff time. |
| Standard parcel or summer route, 6-24 h | Refrigerated route with stronger warm-side protection and no direct ice contact. | EPP or insulated carton shipper, thicker divider, absorbent secondary containment, two loggers for warm and cold positions. | Start trials around 1.5-3.5 kg conditioned 2-8 C gel or PCM for small parcels; increase only after cold-spot review. | Warm edge, cold face, condensation, lisibilité de l'étiquette, et retard de réception. |
| Cold winter route or air transfer | Prevent freezing from ambient exposure while still holding refrigerated control. | Expéditeur à haute isolation, coolant reduced or buffered, non-direct contact layout, payload wrapped in support sleeve. | Use conditioned PCM rather than frozen gel where chill risk is high. Test the lowest expected ambient before live shipment. | Température minimale, cold-spot location, bag flexibility, outer carton dryness, and courier dwell time. |
Use these ranges as a starting point for sampling and quotation. Final coolant, PCM, glace carbonique, isolation, and monitoring choices should be validated with the real payload, taille de l'expéditeur, durée de l'itinéraire, processus de transport, saison, et procédure de réception.
The component should enter a stable refrigerated packout. Do not rely on the box to pull a warm payload back into range.
Utilisez un diviseur, espaceur en mousse, or payload sleeve so gel packs or PCM cannot touch bags directly.
Place documents outside wet zones and use absorbent or leak-resistant containment around the payload.
Place one sensor near the likely warm edge and another near the coolant-side risk point during validation.
These are the visible and operational issues the packout should reduce before the shipment reaches the receiver.
Use the test curve as a working comparison, then validate with the actual payload, expéditeur, coolant or dry ice mass, durée de la voie, profil ambiant, et processus de réception.

Use these pages to compare nearby blood product routes, choix de liquide de refroidissement, options d'isolation, and route-risk questions before sampling.
Red blood cells require controlled chilled transport with careful logger placement. The package should prevent both warming and accidental freezing during handoff.
Geler l'exposition, warm receiving delays, bag pressure points, and poor payload separation are the main failure modes.
Use a qualified blood shipper with a payload compartment, doublure absorbante, and separation from coolant. Keep bags flat enough to avoid pressure damage.
Use qualified 1 à 6 C packaging components. Do not substitute standard frozen gel packs without full validation.
Review minimum and maximum logger data, bag condition, contrôle des fuites, and time from delivery to controlled storage.
Red blood cells require a qualified chilled route, not a generic ice-pack box. The payload area should protect bags from direct coolant and include enough absorbent control for leakage risk.
Utilisation validée 1 à 6 C components and keep the temperature logger in the payload zone. A logger against the cold wall may overstate freeze risk, while a logger outside the payload may miss warming.
Tempk review should cover bag count, masse de charge utile, durée de l'itinéraire, heure de transfert, et flux de travail de réception. Check minimum and maximum temperature, bag condition, fuite, and transfer into controlled storage.
Share the component type, nombre de charges utiles, bag or container size, plage cible, durée de l'itinéraire, conditions ambiantes, courier steps, handoff limit, et recevoir des chèques. Tempk can help compare the shipper, disposition du liquide de refroidissement, support insert, monitoring position, et plan de validation.
