On September 5, 2008 Baxter Healthcare Corporation communicated an Urgent Product Recall,
2008-043 MD, concerning the AS50 Infusion Pump product codes 1M8550 and 1M8550R serviced or
repaired with part numbers AAS5001530RP, AAS5001531RP, or A069160000RP from November 1,
2007 to July 29, 2008.
The Rear Case assemblies were manufactured with ESD grounding squares that may have been
manufactured with the adhesive applied to the incorrect side resulting in exposure of the conductive
surface of the I/O board. Pumps that have been serviced or repaired with these components could short
circuit resulting in a loss of audio and/or interruption of therapy.
