Additional Manufacturer Narrative
The event occurred in the usa during visual inspection with no patient involvement.It was reported that there was a visible crack on the body of the flow bubble sensor.No harm to any person has been reported.As a flow bubble sensor issue, can lead to a pump stop, if the intervention is set by the user, a report is required.A getinge technician was sent for investigation on 2026-09-18.The flow/bubble was replaced.The technician performed safety, calibration, and functionality checks to factory specifications.All function tests are passed.The most probable root cause is an external force applied to the sensor over the years of use, which caused the mechanical damage.Due to the age of the device and this component flow/bubble sensor, age related aspects can be considered, as well.The flow/bubble sensor in question was manufactured in 2020.A complaint historical search of the affected cardiohelp was performed and no previous complaint where the flow/bubble sensor was replaced was reported.Additionally, according to the risk file v24 of the cardiohelp device the following root causes can lead to the reported failure: fail of device by mechanical force e.G.- caused by loose connections caused by - fall of device - wear / loosening of components.According to the instruction for use (ifu) chapter "connecting the combined flow/bubble sensor" the bubble monitoring function test and flow off-set calibration has to be performed before every use.Thus a defective flow/bubble sensor should be detected prior to use, during priming.In addition as the cardiohelp includes pressure sensors and a venous probe it is able to measure and control the blood flow and parameters.If the measured values are above high limit or below low limit of the set limits the system generates a visual and acoustical alarm.In the ifu chapter "using the emergency drive with the disposable hls retainer" is stated that the emergency drive can be used to manually control the blood flow in case of a failed cardiohelp.The review of the non-conformities has been performed on 2026-09-21 for the period of 2018-04-13 to 2026-09-15.It does not show any non-conformity in regard to the reported product and failure.There is no indication that manufacturing issues occurred during this time, thus production related influences are unlikely.The device was manufactured on 2018-04-13.In addition, a review for potential field actions and capas related to the failure and product in this complaint was performed.This complaint is not in scope of any ongoing field actions and/or capas.Based on the results the reported failure "cracked flow/bubble sensor " could be confirmed.The occurrence rate was calculated for the reported issue and it was determined that this is not a systemic issue.Therefore, no remedial action is required.The occurrence rate related to the reported issue is currently being monitored as part of maquet cardiopulmonary's trending program and additional investigations or corrections will be implemented in case of adverse trending.
