A record-literacy guide for perfusion leadership and biomedical teams buying refurbished heart-lung and perfusion equipment, current as of September 2026. It is not clinical guidance, and it does not claim that every seller provides every record described here.

With most equipment, a missing document is an inconvenience. With perfusion equipment, missing records change what you can safely place into service, because the device performs a circulation function and the accessory set it runs with is itself regulated and traceable. That is why the records question comes first in this category, before price and before condition.

Why perfusion equipment demands stronger records

Four characteristics raise the bar. The devices are high-consequence: an unexpected failure is not a scheduling problem. They are frequently maintained by specialist providers rather than in-house teams, which obscures the maintenance history. Their consumables ¡ª circuits, oxygenators, cannulae ¡ª are sterile single-use items with lot and expiry records of their own. And their configurations can change over a device’s life through software updates and component replacement.

Together those characteristics mean that the record set, rather than the physical device, is often what determines whether a purchase is a sound decision.

Service and preventive maintenance history

Ask for the history against the serial number, not against the model. What you are looking for is continuity: dates, the work performed, the organization that performed it, and the parts used. Gaps are not automatically disqualifying, but they are pricing information ¡ª an unbroken history supports a higher value, and a gap shifts the risk of a latent fault towards the buyer.

• Serial-matched service events in date order, with the provider named.
• Preventive maintenance performed to the manufacturer’s schedule.
• Corrective repairs, including what failed and what was replaced.
• Parts provenance where components have been replaced.

Safety test and calibration reports

Safety testing and calibration are different from maintenance, and the records should be separate. What you need to see is the test performed, the values recorded, the acceptance basis used, and the identity of the test equipment ¡ª because a result without the instrument’s calibration status is not evidence.

Where a device includes measurement functions, ask specifically for the calibration record for those functions and for the date of the most recent verification. Where a device depends on disposables whose performance affects the system, ask whether the seller holds documentation for the accessories supplied with it.

Software and configuration records

Software state determines what a perfusion device can do and which accessories it supports. Ask for the current version, the update history, and whether any update requires manufacturer involvement. Then confirm that the accessories included with the unit are supported by that version ¡ª a mismatch here is one of the more expensive discoveries a buyer can make after delivery.

Single-use and sterile disposables paperwork

Where consumables travel with the sale, they need their own records: lot numbers, expiry dates, and evidence that the sterile packaging is intact. For sterile single-use items the practical check is straightforward ¡ª in date, lot recorded, barrier intact ¡ª and any item that cannot answer all three should be quarantined rather than counted as part of the purchase.

Accessory and consumable completeness

Perfusion equipment is rarely usable as a bare console, and the accessory position deserves its own line in the record review. Establish what the device requires to run, what of that is included, and what will have to be purchased separately. Where the answer involves single-use items, the volume supplied with the sale, their expiry dates and their storage history all bear on value. A unit sold with a short-dated consumable set is not the same offer as one sold with a fresh set, even when the equipment is identical.

Building the acceptance test plan

Missing records: risk and remedy

Where a record is missing, three remedies are available, and they can be combined. The first is to commission the verification yourself after delivery, using a qualified provider, and to make acceptance conditional on the result. The second is to price the gap: a device without a service history is worth less than one with a documented history, and the discount should reflect the work you will do to close the gap. The third is contractual ¡ª an inspection window with a remedy if the device fails verification.

What is not a remedy is reassurance. “It was serviced regularly” without a record is a statement about the seller’s belief, not about the device; the record is what converts it into evidence you can rely on later.

Questions buyers ask

Is a refurbished device without service records worth considering?

Sometimes, at the right price and with a verification plan that you commission yourself. The purchase then becomes a device plus a testing project, and the budget should reflect both.

What single record matters most?

The serial-matched service and test history. It is the record that ties everything else to the physical device you are buying, and it is the one most often incomplete.

How do consumables affect acceptance?

Sterile single-use items are accepted on their own terms: in date, lot recorded, packaging intact. They should be counted and recorded separately from the durable equipment.

Ask for the record pack before you negotiate, and build the acceptance plan around whatever is missing. If you are evaluating perfusion equipment and want to know what documentation travels with a unit, ask HHG for the records on a specific item, or browse the current cardiac and perfusion listings.
