Maquet HL 20 heart-lung machine

Name: Maquet HL 20 heart-lung machine
Brand: HL 20

The HL 20 is Getinge's modular roller pump heart-lung machine, sold under the Jostra and then Maquet names, which drives, controls and monitors extracorporeal circulation. During bypass the HL 20 does the heart's pumping while a disposable oxygenator handles gas exchange. It sits on a console holding four or five roller pumps, with mast mounted accessories. Public technical data are sparse, so this note leans on FDA recall and device identifier records.

Sources

Where this note comes from.

Not covered: Sources are thin. The HL 20 510(k) summary (K943803, 1996) is not online, Getinge's product page no longer shows HL 20 detail, and the user manuals found online sit on a third party site that refused access, so flow ranges, battery backup time, sensors, electrical ratings and alarm messages are not included. No error codes were found in an opened public document. Recalls are mostly from 2006 to 2011; newer field actions may exist under other names such as HL 40. Recall text was read through openFDA because FDA recall pages returned errors at drafting time.
