FDA (Devices) recall action 92956
The FDA (Devices) publishes a recall like this one as 6 separate product records. They share a firm, a date and a cause; this page is all of them in one place, so the scale of the action is visible rather than spread across 6 pages.
A force sensor in the occlusion detector may drift out of calibration leading to increased occlusion detection times, false occlusion alarms, or a System Failure Alarm. If the force sensor calibration shift is large enough, the pump will display a System Failure Alarm (including Force Sensor BGND Test, Force Sensor Bridge Test, or Force Sensor Test). However, if the calibration shift is not large enough to trigger a System Failure Alarm, the threshold to detect an occlusion may increase, increasing the time to occlusion detection, or the threshold may decrease, leading to false occlusion alarm…
The agency’s own wording, quoted from the enforcement report.
The unit total adds up the quantities the agency stated for each product. Where a product record gave no figure, or gave a weight rather than a count, it contributes nothing — so the real total is at least this, never less.
Smiths Medical is recalling Medfusion Model 3500VX-500 Syringe Pumps due to force sensor calibration drift that can cause false alarms, system failures, or delayed occlusion detection.
Smiths Medical is recalling Medfusion infusion pump components due to a force sensor calibration issue that may cause delayed occlusion detection, false alarms, or system failures. No injuries have been reported.
Smiths Medical is recalling Medfusion Syringe Pumps due to force sensor calibration drift that may delay occlusion detection or trigger false alarms. About 67,507 pumps are affected, distributed in the US and Canada.
Smiths Medical is recalling 118 units of Medfusion infusion pump plunger case components due to potential force sensor calibration drift. The sensor may malfunction, leading to delayed occlusion detection, false alarms, or system failure.
The Medfusion Syringe Pump Model 3500-500 may experience force sensor calibration drift, causing false alarms or delayed occlusion detection. Approximately 20,815 units are being recalled worldwide, with increased risk in devices manufactured before April 2022.
Smiths Medical Medfusion syringe pumps may have force sensors that drift out of calibration, causing delays in detecting line occlusions or triggering false alarms. Devices produced before April 2022 are at higher risk.
